Lateral static overload on immediately restored implants decreases the osteocyte index in peri-implant bone: a secondary analysis of a pre-clinical study in dogs.

OBJECTIVES: This animal study was conducted to evaluate the osteocyte index in the peri-implant bone around immediately restored implants under static lateral overload. MATERIAL AND METHODS: Seven mongrel dogs received three implants on each side of the mandible. Forty-two implants were distributed into three groups (14 implants per group); each animal received two implants connected to a 4.5-mm opened expansion device (experimental group); in the other mandible side, two implants were connected into an expansion device without activation (control group); one implant each side of the mandible was left submerged (unload group). After 4 months under daily mechanical and chemical plaque control, the animals were euthanized; dental implants and surrounding bone were removed and processed to obtain thin ground sections. Histomorphometry was used to evaluate the osteocyte index in the peri-implant bone contact to implant. RESULTS: A higher, statistically significant mean number of osteocytes × 10-5 µm2 (54.74 ± 23.91) was found in the control group compared with the test group (22.57 ± 22.55) (p = 0.0221). The correlation between percentage of bone-implant contact and osteocyte index for submerged implants was not statistically significant (p = 0.2667), whereas the value for immediately loaded implants was statistically significant (p = 0.0480). CONCLUSION: The lower number of osteocytes in the peri-implant bone around overloaded implants could be related to the need for functional adaptation of the bone tissue to overloading and to the hypothesized involvement of the osteocytes in the maintenance of the bone matrix in the control group. CLINICAL RELEVANCE: Osteocytes play a pivotal role in bone adaptation to mechanical loading, and the osteocyte network has been regarded as being the main mechanosensory mechanism.

Indenizações e processos jurídicos em Implantodontia: uma revisão no Brasil entre 2006 e 2016 / Compensation and legal processes in Implant Dentistry: a Brazilian review from 2006 to 2016

Objetivo: o presente estudo teve como objetivo averiguar as características dos processos cíveis de reparação de danos contra cirurgiões-dentistas, bem como o montante dessas reparações. Material e métodos: uma busca eletrônica foi realizada com o termo "implante dentário" em sites oficiais do Tribunal de Justiça de Santa Catarina, Superior Tribunal Federal e Supremo Tribunal Federal, entre 2006 e 2016. Os principais desfechos investigados foram: 1) pertinência dos processos contra cirurgiões-dentistas; 2) evolução dos processos; 3) sexo do reclamante; 4) personalidade jurídica do réu; 5) condenação ou absolvição; 6) tipo de decisão; e 7) valor das indenizações. Resultados: dos processos analisados neste estudo, 63% eram reclamações contra cirurgiões-dentistas. Dos autores das ações, 80% eram do sexo feminino. A maioria dos réus era pessoas jurídicas. Os profi ssionais de Odontologia foram condenados na maior parte dos processos. A decisão monocrática foi maioria ampla no tipo de decisão. O valor médio das indenizações foi R$ 20.123,07 para danos morais e R$ 15.020,55 para danos materiais, totalizando R$ 35.143,62. Conclusão: o crescimento do número de reclamações contra cirurgiões-dentistas nos últimos anos nos leva a tomar atitudes para evitar que esses processos resultem na condenação do profissional, entre elas: a melhora das relações paciente/profissional e a importância de um constante aperfeiçoamento profissional. Além disso, demonstra a necessidade do termo de consentimento livre e esclarecido, detalhado e bem explicado, com planejamento, riscos, possíveis mudanças, preços e alternativas de tratamento.

Objective: the present study aims to investigate the characteristics of civil damage repair against dental surgeons, as well as the amount of these reparations. Material and methods: an electronic search using the "dental implant" as key word was performed at official sites of the Court of Santa Catarina, Superior Court and Federal Supreme Court between 2006 and 2016, resulting in data about whether the processes are against dental surgeons, progress of process, gender, defendant's legal personality, conviction or acquittal, type and value of the claims. Results: about the processes ana lyzed in this study, 63% were complaints against surgeons and these processes have grown in recent years. The authors of the actions were represented by a percentage of 80% women. Most of the defendants were legal entities. Dental professionals were condemned in most cases. The monocratic decision was most extensive in the kind of decision. The average value of claims was in R$ 20,123.07 for moral damage and R$ 15,020.55 to property damage, totaling R$ 35,143.62. Conclusion: the increase in the number of complaints against surgeons in recent years leads us to take action to prevent these processes resulting into professional conviction, including the improvement of patient-professional relationship and the importance of constant professional improvement. In addition, it demonstrates the need for using of an informed consent form, detail
