Dissertations / Theses on the topic 'Dental arch; Occlusion (Dentistry)'

Occlusal asymmetries are common in orthodontic patients. A treatment option for correcting moderate asymmetries is asymmetric extractions. This study evaluated post-treatment dental arch symmetry in patients treated with unilateral premolar extractions. Post-treatment casts of 60 patients were divided into four treatment groups based on the history of occlusal asymmetry and the treatment plan. DesignCAD3000 software (Upperspace Corporation, Pryor, OK) was used to evaluate asymmetrically treated arches for symmetry. The four treatment groups were compared to identify differences in arch asymmetry based on treatment. The lateral incisor and canine were found to be more palatal on the extraction side in patients treated with unilateral extractions (P < .001). Arch length increased (P < 0.001) and area under the arch decreased (P < 0.01) on the extraction side. On average, patients with asymmetric extractions did not finish with more arch asymmetry than those without asymmetric extractions.

Objectives: Orthodontic arch development expands and broadens the dentition beyond the confines of the original arch perimeter. This is often accomplished by means of self-ligating fixed appliances. When movements take the teeth outside those confines, without adoption, the muscular forces are unbalanced and may lead to dental relapse. Muscle spindles and associated reflex loops within the tongue provide feedback to arch perimeter changes that may produce postural changes to the new archform. Resting posture has long been accepted as aiding in tooth position. The objective of this study was to assess the oral and pharyngeal postural changes that result from arch development with the Damon system and report the amount of expansion accomplished. Methods: Pre- and post-treatment models and lateral cephalograms were collected on 69 previously treated orthodontic patients from four different private practices. Expansion was measured from the buccal cusp tips of the first and second premolars and first molars. A new cephalometric analysis was implemented to diagnose both variations in malocclusion and variations in posture of the head, neck, pharynx, hyoid bone and tongue. Results: Both tongue height and length increased, 2.9mm (P-value 0.001, SEM=1.06) and 3.76mm (P-value 0.00002, SEM=0.62) respectively, following posterior dental arch expansion using Damon archwires. Hyoid position was not significantly different. Conclusion: As dental arches are expanded the tongue increases in both length and height to fill the space and therefore may aid in stability during the retention phase of treatment. The lack of change in hyoid bone position, as one would expect with a rise in tongue position, might be explained by either slight changes in head position or the need to maintain the airway.

As fissuras labiopalatinas alteram o crescimento e o desenvolvimento do complexo maxilo-mandibular, assim como todas as funções orofaciais. As cirurgias reparadoras primárias representam o maior agente modificador do crescimento maxilo-facial, de forma a restringi-lo. O sucesso do tratamento reabilitador do paciente fissurado depende da correta atuação de uma equipe multidisciplinar. Este trabalho teve como objetivo avaliar as condições oclusais em modelos de gesso de pacientes portadores de fissura labiopalatina completa, não sindrômicos, correlacionando o prognóstico ao tipo de fissura, fase de desenvolvimento da dentição, gênero e hospital de reabilitação cirúrgica. Utilizou-se 87 pares de modelos das arcadas dentárias de pacientes fissurados do Ambulatório da Disciplina de Prótese Buco Maxilo Facial da Faculdade de Odontologia da Universidade de São Paulo, que haviam sido submetidos às cirurgias reparadoras primárias em cronologia clássica (queiloplastia 3 a 6 meses e palatoplastia 18 meses), sem enxerto ósseo alveolar e/ou tratamento ortodôntico prévio. O grupo estudado foi composto de 57 pacientes com Fissura Labiopalatina unilateral, com idade média de 6 anos e 5 meses e 30 pacientes com Fissura Labiopalatina bilateral com idade média de 6 anos e 2 meses. Para a classificação dos modelos em gesso de fissurados unilaterais, foram utilizados o Índice de 5 anos e o Índice de Goslon, na dentição decídua e mista respectivamente, enquanto que para as fissuras bilaterais empregou-se o Índice de Bilateral. Os três índices referidos compreendem uma escala de 1 a 5, com grau crescente de severidade de má oclusão. Os modelos foram avaliados pelo pesquisador e mais 2 examinadores, em dois momentos distintos, quando se alcançou um alto grau de confiabilidade e reprodutibilidade (Teste de Cronbach e Análise de Correlação de Spearman). Posteriormente, para as análises complementares, utilizaram-se apenas os dados fornecidos pelo pesquisador, os quais foram agrupados em prognóstico dos resultados a longo prazo em: bom (graus 1 e 2); regular ( grau 3 ) e pobre ( graus 4 e 5 ). Aplicou-se o Teste da Razão de Verossimilhança para verificar as possíveis diferenças entre as variáveis de interesse, quando não se encontrou, para a amostra total, correlação entre prognóstico e tipo de fenda, gênero e hospitais de reabilitação. Apenas nos pacientes com fissuras unilaterais houve associação do prognóstico à fase de dentição (p=0,019) e aos hospitais de reabilitação (p=0,025). Este trabalho permitiu concluir que as fissuras unilaterais na fase de dentição decídua mostraram menor severidade de má-oclusão, e que o Hospital de referência da Faculdade de Odontologia da Universidade de São Paulo apresentou resultados mais favoráveis em relação aos demais.
The cleft lip and palate alter the growth and development of the maxillo-mandibular complex as well as all orofacial functions. Primary repair surgery represents the largest modifier agent of maxillofacial growth in order to limit it. The success of the rehabilitation treatment of the cleft patient depends on the correct performance of a multidisciplinary team. This study aimed to assess the occlusal conditions, in plaster models, of patients with complete cleft lip and palate, non syndromic, correlating to the type of cleft, stage of dental development, gender and surgical rehabilitation hospital. For this study, 87 pairs of casts from cleft patients of the Ambulatory of Oral Maxillo Facial Prosthesis of the Faculty of Dentistry of the University of São Paulo (USP), that had been undertaken to primary classical repair surgeries (cheiloplasty 3 to 6 months and palatoplasty 18 months), without prior alveolar bone graft and/or orthodontic treatment. The group studied was composed of 57 patients with unilateral cleft lip and palate, with mean age of 6 years, 5 months and 30 patients with bilateral cleft lip and palate with mean age of 6 years, 2 months. For the classification of plaster casts for unilateral cleft, the index of 5 years and the index of Goslon, in the deciduous and mixed dentition, respectively, whereas the Bilateral index was used for bilateral cleft. The three mentioned indexes comprise a scale of 1 to 5, with increasing levels of severity of malocclusion. The models were evaluated by the researcher and two other examiners in two distinct occasions, when a high degree of reliability and reproducibility was reached. Subsequently, for the additional analysis, it was used only the data provided by the researcher, which were grouped into long-term prognosis results in: good (grades 1 and 2); regular (grade 3) and poor (grades 4 and 5). The likelihood ratio test was used to verify the possible differences between the variables of interest, and the results did not show, for the total sample, any correlation between prognostic and cleft type, gender, and rehabilitation hospitals. Only patients with unilateral clefts there was an association of the prognostic to the dental stag of dental development (p=0.019) and rehabilitation hospitals (p=0.025). This study revealed that the unilateral clefts in the deciduous dentition stage showed a lesser severity for poor occlusion, and that the Referral Hospital of the Faculty of Dentistry of the University of São Paulo has the most favorable results compared to others.

Resumo: O índice de Carrea constitui uma importante ferramenta na estimativa da estatura humana, necessitando para sua aplicação apenas que alguns elementos dentais anteriores inferiores estejam preservados. No entanto, nos casos em que a mandíbula é acometida por um trauma, uma patologia ou por situações diversas, o uso da técnica torna-se inviável. Com isso, ampliar a utilização do índice de Carrea, estendendo-o aos elementos superiores, aumentaria as chances de se realizar o método, principalmente nos casos em que apenas o crânio é encontrado. Diante disso, o presente estudo teve como proposição testar um novo denominador no índice de Carrea, para que o mesmo possa ser utilizado no arco superior, visando um novo recurso para se estimar a estatura humana. Além disso, objetiva-se comparar os percentuais de acerto obtidos entre o arco inferior e superior. Para tanto, foi realizado um estudo com 378 modelos em gesso, sendo 189 superiores e 189 inferiores de arcos dentais correspondentes, pertencentes a alunos do curso de Odontologia da Universidade Federal da Paraíba, de ambos os sexos e com idades entre 18 e 30 anos. A estatura dos participantes foi estimada mensurando, com um paquímetro digital, os incisivos central e lateral e o canino, dos arcos superiores e inferiores, bem como dos hemiarcos direito e esquerdo. A partir dessas medidas, foram estimadas, por meio do índice de Carrea, as alturas máxima e mínima com base nos arcos inferiores. Para os arcos superiores foi utilizada uma modificação no denominador da fórmula original de Carrea, de valor 2 para o valor 2,55, de forma que a mesma se adequasse às medidas da maxila. Os valores obtidos foram comparados à estatura real dos participantes, previamente mesurada com um antropômetro. No arco superior, verificou-se diferença estatisticamente significante entre os posicionamentos dentais no sexo masculino e nos hemiarcos direitos, sendo os apinhados o maior percentual de acerto (65% e 65,2%, respectivamente). A avaliação interarcos proposta entre os sexos, para os três tipos de posicionamento dental, demonstrou percentual de acerto estatisticamente significante no sexo feminino entre os hemiarcos normais, com os inferiores apresentando percentual maior (70,0%) em relação aos superiores (42,3%). Já entre os hemiarcos, a diferença estatística pôde ser observada nos lados direito e esquerdo, apenas no posicionamento normal, com os inferiores demonstrando percentuais de acerto maiores (61,5% e 67,6%, respectivamente). Dessa forma, conclui-se que, embora o percentual de acertos no arco superior não tenha sido significante, o método poderá ser utilizado como subsídio para a estimativa da estatura
Abstract: Carrea's index is an important tool in human stature estimation, and requires for its use only some lower anterior teeth preserved. However, in cases of mandibular damage - by trauma, pathology or any other condition - the use of the method becomes impossible. Therefore, expand the use of Carrea's index, extending it to upper dental elements, increases the applicability of the method, especially in cases where only the skull is recovered. Thus, the present study aimed to test a new denominator for Carrea's index, so that it can be used in the upper jaw, which provides a new resource for human stature estimation. The study was conducted with 378 cast models - 189 higher and 189 lower arches - of dentistry students from the Federal University of Paraíba, of both sexes and aged between 18 and 30 years. The stature of the participants was estimated by measuring, with a digital caliper, the central and lateral incisors and canine from upper and lower arches, both sides. From these measurements, the maximum and minimum stature was estimated, according to Carrea's index. Moreover, it was aimed to compare the sucess rates between the upper and lower arches. For the upper arches a new denominator of Carrea's original formula, from 2 to 2.55, so it would fit the the maxilla's measures. The values obtained were compared to the real stature of the participants, previously measured with an anthropometer. In the maxillary arch, there was a statistically significant difference between the teeth alignment in males and in the right hemiarch, with the crowded hemiarches showing the greatest accuracy (65% and 65.2% respectively). The interarch evaluation proposed between the sexes, for the three types of dental alignment proved percentage of success statistically significant in females between the normal hemiarches, with the lower arch showing a higher percentage (70.0%) compared with the upper one (42.3%). Among the hemiarches, statistical difference was observed in right and left sides only in normal position, with the lower arch showing greater success rate (61.5% and 67.6% respectively). It can be stated that although the percentage of success in the upper arch was not significant, the method proposed can be used as additional criteria for the estimation of stature

Background: Maximal voluntary occlusal bite force (MVOBF) is the maximal force applied by the jaw muscles in dental occlusion. MVOBF is one parameter for functional capacity of the jaw system.  Aim: To evaluate MVOBF in different positions in the bite and to evaluate possible intra-individual differences between sessions.  Methods: MVOBF was measured with an electronic bite force device, with transducers sensitive to force, in 20 healthy men (mean 24.5 years). Eligibility of participants was full dental occlusion, Angle Class I relation, no diagnosis according to Diagnostic criteria for temporomandibular disorders. The test included three repeated measurements on each site: first molar right, first molar left and central incisor, in random order, with test-retest study design. Unpaired T-test was used to test the MVOBF in different positions in the bite and paired T-test for possible intra-individual differences between sessions. A post hoc test for repeated measure one-way ANOVA was added.  Results: MVOBF in different positions in the bite was lower in the incisor area compared with the molar region (P<0.0001), but similar between right and left molar side (P=0.48 and P= 0.96, respectively). No intra-individual differences between sessions (molar right P= 0.40; molar left P= 0.81; incisor area P= 0.66). The intra-individual variability for repeated measurements showed variability for incisor area (P= 0.007), but not for molar right and left region (P=0.95 and P=0.49, respectively).  Conclusion: The results may provide reference values for MVOBF in young adult men, to be compared with men with pain or dysfunction in the jaw system.

OBJECTIVES: The objective of this research is to evaluate variation of mandibular arch forms at different heights and to determine if there is any correlation between occlusal arch and sub-gingival arch forms. METHODS: 44 subjects were selected based on the inclusion criteria and their CBCTs then were imported to Mimics software (Materialise NV, Belgium) and traced. Each tooth was sliced midsection at 4 different heights: Occlusal, CEJ, Apex and 5mm apical to the apex. At occlusal level the midpoint of the crown was calculated mesiodistally as well as buccolingually. Subsequently, midpoints between the buccal and lingual plates were located for every tooth between and including the first molars. The points were connected forming 4 splines, which then were exported to Geomorph software (cran.r-project.org, Geomorph package, Dean Adams author, Iowa State 2015) for shape statistical analysis. RESULTS: The variation in the arch form among subjects is significantly smaller in the Occlusal and CEJ level. The variation at apical and basal bone levels are higher than the variation at CEJ and occlusal levels. However, variation between apical and basal bone levels are minimal. CONCLUSIONS: Mandibular dental arch form demonstrate more variation apically. It may be concluded that dental arch form variation should be considered when using standardized arch forms for different patients. The subgingival arch forms cannot be predicted from occlusal arch form. Occlusal arch shape and form may not be an indication of basal bone arch form. More information needed for detection of correlation between occlusal arch and sub-gingival arch forms.

PURPOSE: To determine the prevalence of Sleep Disturbances (SD) in children and to evaluate the correlation between dental classification and airway dimensions. METHODS: Children between 3 – 18 years at the Boston University Pediatric Oral Healthcare Center in Boston, Massachusetts were recruited for this study. Based on parents’ responses in a brief sleep-screening questionnaire, cases were identified as children with SD and controls were those without. Another detailed questionnaire was used to collect information on demographics and sleep patterns. Clinical and upper airway examinations were conducted using Eccovision Acoustic Rhinometer (AR) and Acoustic Pharyngometer (AP). Statistical differences in upper airway measurements by type of dental occlusion were evaluated. RESULTS: Among 281 children, the prevalence of SD was 38%. Upper airway measurements among 176 participants using AP showed significantly higher pharyngeal Minimum Cross-Sectional Area (MCA) for class III dental occlusion compared to class I (P=.036) in children with SD. Statistically significant differences in MCA, Airway Volume (AV), and minimum distance to MCA by type of dental occlusion were mainly observed among children with SD (P<.05). CONCLUSIONS: The results highlight a possible correlation between nasal and pharyngeal airway dimensions and dental classification among children with SD. Further analysis that include radiological examinations may help in confirming these findings.

A respiração oral é um problema muito presente nas crianças, podendo ocorrer por hábitos deletérios como por obstrução das vias aéreas. A respiração oral pode provocar alterações no crescimento orofacial causando uma desarmonia no sistema estomatognático, o diagnóstico precoce é de vital importância na interceção deste hábito pernicioso. A disfunção deverá ser estudada como um todo, na sua componente dentária, muscular e postural. Um justo conhecimento dos sinais e sintomas é de primeira importância para a interceção do problema e a prevenção das consequências nefastas a longo prazo. O tratamento deverá ser uma abordagem multidisciplinar, no qual poderão colaborar o Medico Dentista, Otorrino, Terapeuta da fala e Pediatra na reposição da função respiratória normal.
Oral breathing is a very present problem in children, and may occur due to deleterious habits such as obstruction of the airways. Oral breathing can cause changes in orofacial growth causing a disharmony in the stomatognathic system, early diagnosis is of vital importance in the interception of this pernicious habit. The dysfunction should be studied as a whole, in its dental, muscular and postural components. Oral breathing is a deviation from the normal growth and development of the child that can have harmful consequences in the long term. The treatment should be a multidisciplinary approach, in which the Dentist, Otorhinolaryngologist, Speech Therapist and Pediatrician can collaborate in the replacement of normal respiratory function.

O presente relatório de atividade clínica trata-se de um estudo refletivo por parte da autora do trabalho efetuado durante o seu tempo de atividade clínica (Abril 2016 e Junho 2018) na Clínica Dentária Universitária da UCP (Instituto de Ciências da Saúde, Viseu). Permite assim a introspeção acerca dos conhecimentos adquiridos, de forma a criar uma base sólida de referências para trabalho futuro. Foi assim efetuado uma análise estatística descritiva da amostra de pacientes cujo tratamento foi efetuado pelo binómio da autora. Esta análise foi realizada inicialmente de forma geral, caraterizando em relação ao tipo de trabalho (distribuição por área disciplinar e segundo a ação da autora como operador/assistente) ou segundo as caraterísticas individuais (género, antecedentes clínicos, hábitos de risco). De seguida foi executada a análise especifica para cada área disciplinar. Nomeadamente para as áreas de: Medicina Oral, Dentisteria Operatória, Periodontologia, Odontopediatria, Endodontia, Cirurgia Oral, Prótese Removível, Prótese Fixa, Oclusão e Ortodontia. Foram estudadas as especificações da amostra de cada uma, em relação aos diagnósticos determinados, tipo de tratamento efetuado e nível de colaboração. O trabalho efetuado ao longo dos cinco anos de formação e consequentes conhecimentos adquiridos tornam-se determinantes para desenvolver as capacidades autónomas do futuro Médico Dentista, tornando-o um profissional competente e responsável.

O presente relatório destina-se a realizar uma análise e discussão fundamentadas da atividade clínica realizada pelo seu autor durante o último ano de formação no Mestrado Integrado de Medicina Dentária (MIMD) da Universidade Católica Portuguesa de Viseu, no período compreendido entre setembro de 2019 e maio de 2020. Trata-se de um método que, permitindo a valorização do futuro profissional no mercado de trabalho, leva a uma profunda reflexão de toda a prática realizada em contexto clínico, com os seus êxitos e as suas falhas, constituindo-se como uma base de aprendizagem muito forte. A ação clínica foi obtida através de dois contextos clínicos com marcadas diferenças, no primeiro semestre no Hospital Odontològic da Universidade De Barcelona, Campus de Bellvitge- Fundació Josep Finestres, em Espanha no âmbito do programa de mobilidade Erasmus + , e o segundo semestre na Clínica Dentária Universitária da Faculdade de Medicina Dentária da Universidade Católica Portuguesa de Viseu. Esta exposição pretende, também, descrever um pouco desta experiência única de contacto com diferentes culturas, formas de trabalhar, procedimentos, ao aumento da capacidade de adaptação a meios adversos através da recolha de dados elaborada, realizando uma contextualização do paradigma da Medicina Dentária em Portugal e Espanha. Os dados recolhidos foram inseridos e avaliados numa base de dados realizada na plataforma Microsoft Office Excel® (2019) (Microsoft®, EUA) tendo-se a partir daí realizado uma análise estatística descritiva fazendo-se referência a aspetos mais gerais como a área disciplinar inserida (sendo que o primeiro semestre foi em contexto de clínica integrada) e a intervenção como operador/assistente e seguidamente a características que dizem respeito ao paciente como a idade, o sexo, o número de consultas, a história clínica, a medicação e os fatores de risco. A frequência nas mais variadas áreas disciplinares conduz o estudante a uma melhor preparação para enfrentar a diversidade de casos que poderão chegar-lhe ao consultório dentário, sendo que as disciplinas com prática clínica foram: Clínica Integrada, Dentisteria Operatória, Ortodontia, Oclusão, Cirurgia Oral, Endodontia, Periodontologia, Prótese Removível, Prótese Fixa, Odontopediatria e Medicina Oral. Por fim, são apresentados casos clínicos concretos com uma ponderação crítica com recurso a referências bibliográficas de literatura científica existente e atualizada.
The purpose of this report is to conduct a reasoned analysis and discussion of the clinical activity carried out by the author of the work during his last year of training in the Integrated Master of Dental Medicine (MIMD) of the Universidade Católica Portuguesa de Viseu, in the period between September 2019 and May 2020. It is a method that, allowing the valorization of the professional future in the job market, leads to a deep reflection of the whole practice carried out in a clinical context, with its successes and failures, constituting itself as a very strong learning base. The clinical action was obtained through two clinical contexts with marked differences, in the first semester at the Hospital Odontològic of the University of Barcelona at Campus of Bellvitge-Fundació Josep Finestres, in Spain under the Erasmus + mobility program and the second semester at the Universitary Dental Clinic of the Faculty of Dental Medicine of the Universidade Católica Portuguesa de Viseu. This exhibition also intends to describe a little of this unique experience of contact with different cultures, ways of working, procedures, increasing the capacity to adapt to adverse environment through the elaboration of clinical data, creating a contextualization of the Dental Medicine paradigm in Portugal and Spain. The collected data were inserted and evaluated in a database carried out on the Microsoft Office Excel® platform (2019) (Microsoft®, USA having since then carried out a descriptive statistical analysis referring to more general aspects such as the subject area inserted (the first semester was in the context of an integrated clinic) and the intervention as an operator / assistant and then the characteristics that concern the patient, such as age, sex, number of consultations, clinical history, medication and risk factors. The frequency in the most varied disciplinary areas leads the student to a better preparation to face the diversity of cases that may reach him / her in the dental office, and the disciplines with clinical practice were: Integrated Clinic, Operative Dentistry, Orthodontics, Occlusion, Oral Surgery , Endodontics, Periodontology, Removable Prosthesis, Fixed Prosthesis, Pediatric Dentistry and Oral Medicine. Finally, concrete clinical cases are presented with a critical weighting using bibliographic references of existing and updated scientific literature.
