Full textIntrinsically, every surgical procedure presents a certain rate of associated intercurrences and/or complications. Hemorrhages, infections, paresthesias or dysesthesias and primary loss of implants are some of the most common intercurrences and complications related to surgical procedures in implant dentistry. This study conducted a retrospective evaluation of the rate of intercurrences and complications related to patients submitted to osseointegratable dental implant placement. A retrospective evaluation was made of 660 clinical record charts of patients submitted to osseointegratable dental implants in the period of 8 years, attended in the Oral and Maxillofacial Surgery Department of Piracicaba Dental School - Unicamp. The results showed that there was a higher rate of intercurrences and complications when patients were attended by residents (p= 0.015) and when the panoramic radiograph was the only preoperative image exam requested (p= 0.011). The results also showed a higher rate of intercurrences and complications in patients when they were submitted to surgical procedures of alveolar bone reconstruction (p< 0.0001). The presence of post-operative infection had a significant influence on the increase in the primary loss of implants (p< 0.0001).

Resumo: Existem várias pesquisas na literatura que relatam fatores considerados de risco para o insucesso dos implantes dentais. Porém, alguns estudos têm gerado controvérsia nos resultados. Alguns autores inclusive contra-indicam o tratamento de implantes dentais na presença destes fatores tais como doenças sistêmicas, abuso de substâncias nocivas à saúde, procedimentos reconstrutivos prévios à implantodontía, complicações pós-operatórias, entre outros fatores, quando alguns estudos demonstram que estes isoladamente representam apenas uma pequena parcela dos insucessos na implantodontia, sendo não significativos. Assim, o objetivo desse trabalho foi avaliar os fatores que podem influenciar na perda tardia dos implantes dentais, por meio de prontuários clínicos dos pacientes que foram tratados com implantes osseointegráveis para reabilitação implantossuportada no período de junho de 2001 a julho de 2006 pela Área de Cirurgia Buco-Maxilo- Facial da Faculdade de Odontologia de Piracicaba . Unicamp. Foram estudados diversos fatores dos pacientes em todos os grupos, tais como gênero, idade, queixa principal, história médica, procedimentos reconstrutivos, procedimentos implantodônticos, desenho do implante, complicações, procedimentos protéticos, acompanhamento mínimo de um ano após carga protética e perda dos implantes. Além disso, cada um destes fatores foi avaliado nos pacientes que apresentaram alguma perda tardia nos tratamentos implantodônticos, com a finalidade de obter a relação destes e sua influência na perda tardia dos tratamentos com implantes dentais. Forem incluídos 432 pacientes na avaliação deste estudo com um índice de 89,3% de sucesso no tratamento com implantes dentais. Perda primaria foi apresentada em 28 pacientes (6,4%) e Perda Tardia em 21 pacientes (4,8%). Dos pacientes que apresentarem perda tardia, nenhum deles relatou consumir substâncias nocivas à saúde, sete apresentavam alguma doença sistêmica e seis forem submetidos a procedimentos reconstrutivos prévios à colocação dos implantes dentais. Os fatores tabagismo, doenças sistêmicas, procedimentos reconstrutivos e complicações nos tratamentos cirúrgicos não resultaram ser significativos nos índices de perda tardia. Estudos prospectivos são necessários para um maior entendimento desses insucessos no tratamento de implantes dentais.
Abstract: Researches in literature considered some factors to be related to failure of dental implants treatments. However, some other studies have generated controversy in those results. Some authors also contraindicated dental implants treatment in presence of these factors like systemic diseases, substance abuse, bone grafting before implant installation, postoperative complications and others factors; when some studies demonstrate that these factors, separately, represent only one small parcel of failures in the dental implantology, being not significant. Thus, the objective of this work was to evaluate the factors that can influence in the delayed failure of dental implantations, by means of formularies of patients who had been treated with dental implants in the period of June of 2001 through July of 2006 at the Oral and Maxillofacial Surgery Department of the Piracicaba Dental School - Unicamp. The groups, such as gender, age, main complaint, medical history, reconstructive procedures, dental implant procedures, complications, prosthetic procedures, a minimum follow-up of one year after prosthetic load and implants failure, had been studied in this research. Moreover, each of these factors had been evaluated in the patients who had presented some delayed failure on dental implants treatments, with the purpose to establish any relation of these factors and their influence in the delayed failure of dental implant treatments. 432patients were included on the evaluation of this study with a success rate of 89.3% on dental implants treatment. Primary failure on dental implants presented on 28 patients (6.4%) and 21 patients (4.8%) presented delayed failure. Patients who presented delayed failure did not abuse substances, seven patients had a systemic disease and six treated previously with bone graft. Smoke, systemic disease, reconstructive procedures and complications during surgical treatments had not resulted to be significant on delayed failure indices. Prospective studies are necessary for a best comprehension of these failures in the treatment of dental implants.

Resumo: Reabilitações na região posterior da maxila são geralmente confrontadas com atrofia óssea, associada à pneumatização do seio maxilar, impedindo a instalação de implantes de comprimento adequado. A cirurgia de elevação do seio maxilar foi introduzida na literatura em 1980, por Boyne & James, para permitir a instalação de implantes osseointegráveis nesta região, apresentando desde então algumas modificações que resultam em diferentes índices de sucesso e de complicações. Este estudo retrospectivo envolveu uma análise de 72 pacientes tratados em um período de 06 anos pela Área de Cirurgia Buco-Maxilo-Facial da Faculdade de Odontologia de Piracicaba - Unicamp. A amostra foi representada por um total de 91 seios maxilares, que receberam elevação associada a diferentes materiais de preenchimento para instalação de 101 implantes. Um total de 70 implantes (69,3%) foi instalado em um segundo procedimento cirúrgico, com um tempo médio decorrido desde a elevação de 9,88± 4,27 meses. Em 13 pacientes (18,5%) a reabilitação implanto-suportada foi abortada. Um total de 35 pacientes (48,61%) encontra-se em fase de reabilitação; 24 pacientes (33,33%) encontram-se reabilitados com próteses implanto-suportadas coroas unitárias, próteses fixas ou overdentures - com um tempo médio de acompanhamento de 25,54 ± 23,75 meses. O índice de sucesso neste período foi de 88,24%
Abstract: Rehabilitation of the posterior maxilla is often impaired by bone atrophy, associated with maxillary sinus pneumatization, preventing the installation of implants of ideal length. Maxillary sinus elevation was first introduced in the literature in 1980, by Boyne & James, as an attempt to allow the placement of osseointegrated implants in this region, and several modifications have been presented resulting in different success and complication rates. This retrospective study involved an analysis of 72 patients treated during a period of 6 years in the Oral and Maxillofacial Surgery Area, Piracicaba Dental School - Unicamp. The sample was represented by 91 maxillary sinuses that had been subjected to elevation associated with different grafting materiais, for the installation of 101 implants. In 13 patients (18.50%), implantsupported rehabilitation had been aborted; in 35 patients (48.61%), it had not been finished; 24 patients (33.33%) had already received rehabilitation with implant-supported prostheses unitary crowns, fixed prostheses or overdentures - with a mean follow-up period of 25.54 ± 23.75% months. The success rate in this period was 88.24%

Introduktion: Tandlöshet är ett problem som drabbar många människor. Kraven på funktionella och snygga tänder i livets alla skeden har blivit tydligare på senare år. Dentala implantat är en möjlighet att ersätta förlorade tänder och har hjälpt många individer att få sin livskvalité tillbaka.
Syfte: Att kartlägga mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat och vilka orsaker det finns till dessa.
Frågeställningar: Vad finns det för mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat?
Vad finns det för orsaker till komplikationer efter behandling med dentalt implantat?
Metod: Studien är en systematisk litteraturstudie.
Resultat: Efter behandling med dentalt implantat kan olika mjukvävnads- och hårdvävnadskomplikationer uppstå. De två vanligaste mjukvävnadskomplikationer var peri-implantär mukosit och mukosal hyperplasi. Typiska hårdvävnadskomplikationer som upptäcktes var benförlust och apikal peri-implantit. Tidigare parodontiterfarenhet visade sig vara den viktigaste orsaken till komplikationer vid dentala implantat.
Konklusion: Dental implantatbehandling är inte riskfri. Studien visade att komplikationer är vanliga efter dental implantatbehandling samt att det fanns riskfaktorer som påverkar dental implantatbehandling på ett negativt sätt.

Ziel der vorliegenden klinischen retrospektiven Studie war die Bestimmung der Häufigkeit des Auftretens und Ausmaßes von Verblendkeramikfrakturen und möglicher Risikoindikatoren. Methode: Die Studie wurde in der Abteilung für Zahnärztliche Prothetik der UniversitätsZahnMedizin Carl Gustav Carus Dresden, Technische Universität Dresden (TUD) geplant und durchgeführt. Erwachsene Patienten (Alter ≥ 18 Jahre), die im Zeitraum von Januar 1995 bis August 2011 mit festsitzenden implantatgetragenen metall- oder vollkeramischen Restaurationen versorgt worden waren, wurden nachuntersucht. Dabei wurden demografische und klinische Parameter erhoben. Unter relativer Trockenlegung wurden alle Restaurationen systematisch auf Verblendkeramikfrakturen untersucht. Die Frakturen wurden in vier Gruppen je nach Ausmaß und Reparierbarkeit klassifiziert. Die Analyse der Daten erfolgte deskriptiv. Weiterhin erfolgte eine Kontingenztafelanalyse der Beziehungen zwischen den demografischen und klinischen Parametern und vorliegenden Verblendkeramikfrakturen auf Patienten-, Restaurations- und Einheitenebene. Ergebnisse: Eine Gesamtzahl von 144 Patienten wurde untersucht; 66 davon männlich und 78 weiblich. Es lagen 507 Einheiten (483 metallkeramisch/MK, 24 vollkeramisch/VK) vor, entsprechend 291 implantatgetragenen Einzelkronen/ verblockten Kronen (278 MK, 13 VK), 28 implantatgetragenen Brücken (28 MK, 0 VK), 16 Verbundbrücken (14 MK, 2 VK) und 14 implantatgetragenen Extensionsbrücken (13 MK, 1 VK). 23,6% der Patienten wiesen mindestens eine Verblendkeramikfraktur auf, wobei 16,4% der MK Brücken, 12,2% der MK Kronen und 9,5% der MK Einzeleinheiten betroffen waren. Die Ergebnisse für die VK Restorationen waren 33,3%, 0,0% und 4,2%. Es konnten Korrelationen zwischen den vorhandenen Veblendkeramikfrakturen und den Parametern Bruxismus, Alter des Patienten, Geschlecht, Anzahl der vorhandenen natürlichen Zähnen, Implantaten und implantatgetragenen Brücken pro Patient, frühere technische Komplikationen, Implantatsystem, Gegenkieferversrorgung und Verblockung der Einzelkronen ermittelt werden. Schlussfolgerung: Verblendkeramikfrakturen bei festsitzenden implantatgetragenen Restaurationen werden als multikausales Geschehen angesehen. Auf der Basis des vorliegenden retrospektiven Studiendesigns wurde ein männlicher Patient mit Bruxismus, über 60 Jahre alt, mit ≤20 vorhandenen natürlichen Zähnen, nicht verblockten Kronen und früheren technischen Komplikationen als Risikopatient für Verblendkeramikfrakturen identifiziert. Die Ergebnisse geben Anlass zu weiteren prospektiven klinischen Studien

Background The application of dental implants in replacing missing teeth is highly predictable and successful. There were some risk factors are recognized to affect the dental implant survival rate or postoperative complications. However, the risk factors in Taiwan patients with implants are not clear. The differences in these risk factors are not available between private dental clinics and dental clinics under teaching hospital. Objective To investigate the risk factors to affect the overall survival rate of dental implants and complication-free survival rate of dental implants. Materials and methods A retrospective study is designed for present study. The inform consent is signed by the patients before data collection .The implants are completed in two cooperated hospitals and one private dental clinic between 2002 to 2014. The data are collected from patients’ medical files. A self-administered questionnaire is used to collect the histories of cigarette smoking, alcoholic drinking, betel quid chewing , and the knowledge, attitude and health behaviors of oral hygiene in patients. Finally, statistical analysis is applied to determine the association. Results The average age of 117 patients ,54 males and 63 females, is 44.58 years old. Total number of implants are 429 including 4 failed implants. The cumulative survival rate was 98.85%. The dental clinics, gender , implant position, brand of implant, postoperative complication and the habit of betel quid chewing were associated with an increased risk of implants failure (P < 0.05).The dental clinics, gender, diabetes, periodontal history, implant position, brand of implant, smoking habit and oral health total score were associated with an increased risk of complications (P < 0.05). Multivariate Cox propositional hazard model also revealed that histories of periodontitis could be a significant risk factor for implant with early complications (adjusted hazard ratio (AHR) = 2.63, 95% CI = 1.22-5.66). Located at maxillary implant has a higher probability of early postoperative complications than mandible (AHR = 1.68, 95% CI = 1.19-2.38). The smokers who implanted in dental clinics were associated with an increased risk of early complications (AHR = 3.42, 95% CI = 1.95-6.01). Conclusion Present study shows that the success rate of dental implants is high while the failure rate is low. Diabetes, histories of periodontitis, implant position, and brand of implant can affect the survival rate of the implant and the chance of occurring postoperative complications. We also found that there are different risk factors between private dental clinics and dental clinics under teaching hospital. Currently, the number of our data collection location were too few, may not represent the actual situation, relevant findings still need further confirmation.

Full textDental implant teraphy has become very popular because of it’s predictable results in the reabilitation of edentulous sites, allowing the reduction of phonetic, aesthetic and functional consequences that come with tooth loss, and it does so by using a fixed and well-accepted solution. However, implant therapy must be carefully weighted as each pacient is unique. This is a literature review about risk factors, failures and complications inherent to implant therapy. The risk factors were organized according to it’s relationship with the surgeon’s experience, thecnique and surgical procedure; the patient; local factors such as bone and soft tissue quantity and quality; factors regarding the implant itself (dimentions, surface treatment and design); factors related to the prosthetic phase, such as type of prothesis and loading; and peri-implant deseases such as mucositis and peri-implantitis. A research was done using the online database MEDLINE/PubMed on the key-words “implantology risk factors”, “complications in implantology”, “implantology failures”, then the articles and publications found were used according to it’s relevance to the present work. Whilst the success rates of implant therapy are high, there are still failures. There are no absolute contraindications to implant therapy, nevertheless some conditions are considered a major risk. The challenge in implantsuported- rehabilitations relies on the physician's ability to evaluate and classify the constraints of each patient, and deliver a treatment plan according to these multifactorial limitations.

Full textIntroduction: Implant-supported prostheses are one of the options available to rehabilitate an edentulous space. This type of dental prosthesis involves several components and steps in their production that may affect the success of the rehabilitation. The characterization of this prosthesis and the record of its possible complications may be helpful in the optimization of this type of rehabilitations. The aim of this study is to characterize implant-supported prostheses produced by Portuguese Dental Technicians. Material and Methods: The data was collected using a questionnaire applied to Dental Technicians. The survey was developed in the online platform Qualtrics® and shared by 3 ways: e-mail to Dental Prostheses Laboratories; e-mail to Portuguese Association of Dental Technicians (APTPD), and request with the survey link in Portuguese online forums of Dental Technicians. Reminders were sent every week, during a month. Results: A total of 155 surveys were answered. However, only 60 were considered for the valid sample. 95 were excluded because they were incomplete. The majority of the Dental Technicians, 68,3%, performed both fixed and removable implant-supported prostheses. Only 6,7% performed exclusively removable implant-supported prostheses. The majority of the fixed implant-supported prostheses is cement-screw (53,6%) or only screw-retained (44,6%). In the anterior sector, the material most used is zirconia with vestibular veneering. In the posterior section, stained monolithic zirconia. The most frequent repair demand is due to restauration chipping. Concerning removable implant-supported prostheses, the most used attachment is “locator®” type and the most frequent repair is the fracture of tooth or denture base, and tooth loss. Conclusion: Within the limitations of this research, we can conclude that restauration chipping is still one important complication in prosthetic rehabilitations with dental implants. This should alert Dental Technicians and Dentists to improve material selection, framework design and occlusion. The fractures that may occur on removable implant-supported prostheses should also alert the professionals for a better prosthetic design and the correct fit of the prostheses in their support area.
