“…Posteriormente realiza-se odontosecção removendo-se a coroa do dente incluso e mantendo-se a raiz no alvéolo dentário, 3-4mm abaixo da crista óssea. Nesta etapa é importante que haja o fechamento primário da ferida cirúrgica, evitando possíveis infecções (10,13,14).…”

“…Destes, 53,33% foram devido à migração radicular que resultaram em exposição das mesmas na cavidade bucal, 10,47% foram oriundas de infecção, 9,52% devido a dor e 9,52% devido a presença de esmalte residual. O autor concluiu que a necessidade uma segunda cirurgia apesar de ser uma desvantagem da técnica, não é uma falha e a coronectomia é uma alternativa cirúrgica segura para a extração de terceiros molares inferiores intimamente relacionados com o canal mandibular (BARCELLOS et al, 2019). No presente caso relatado a paciente apresentou dor compatível com procedimento cirúrgico e após seis meses não foi observada exposição da raiz na cavidade oral, bem como nenhum histórico de infecção (13).…”

A coronectomia ou odontectomia parcial intencional é uma alternativa cirúrgica para a exodontia de terceiros molares inferiores que apresentam algum grau de proximidade com o canal mandibular (CM). Esta técnica consiste na remoção da porção coronária do dente incluso e parte de suas raízes permanecem intactas dentro do alvéolo dentário. Deste modo pode-se reduzir as chances de lesão ao feixe vásculo-nervoso alveolar inferior. O objetivo deste trabalho é relatar o caso de uma paciente que se submeteu a coronectomia de um terceiro molar inferior impactado, que apresentava suas raízes em íntima relação de contato com o CM.

“…2,[21][22][23] This compares with 0-10.47% as reported by other studies. 4,9,29,30 Long et al 30 reported a risk ratio (RR) of 1.03 (95% CI = 0.54-1.98) in their meta-analysis. O'Riordan 3 found only 1 case of infection in a retrospective study of 52 patients while other papers reported no cases of infection.…”

“…28,33 It has been suggested that this is the result of different follow-up periods in the literature ranging from 6 months to 10 years. 29,33 Three of the four included studies reported root migration was very common. 2,13,23 Renton et al 21 was the only study reporting relatively low numbers of root migrations.…”

“…This may be one possible factor leading to low rates of root migration in the study by Renton et al 21 . Indeed reports in the literature indicate factors such as age, 31 gender, 34 root morphology 29 and depth of impaction 34 may be correlated with the incidence of root migration up to 24 month postop. Such factors were inadequately reported in the included studies to allow any strong conclusions to be drawn.…”

Background: Extraction of mandibular third molars (M3M) close to the inferior alveolar nerve (IAN) has a higher risk of neurological disturbance. This review aims to evaluate the evidence supporting the use of the coronectomy technique compared to complete extraction for such M3Ms. Case studies by a specialist oral and maxillofacial surgeon are included to illustrate clinical practice. Methods: Three databases (Cochrane Library, Embase, PubMed) were searched (November 2020). Additional articles were sought by hand searching the reference list of included articles. All studies published in English comparing outcomes of coronectomy with complete extraction with at least 50 subjects and 6 months follow-up were included. Results: Of the six included studies, five reported a lower rate of IAN disturbance after coronectomy compared with complete extraction. There were no reported cases of lingual nerve disturbance. Other outcomes of coronectomy such as pain, infection, alveolar osteitis were either similar or lower compared to complete extraction. There were high rates of root migration but low rates of exposure and reoperation. Follow-up protocols varied considerably. Conclusions: There is medium quality evidence to support the option of coronectomy for high risk M3M cases. Further studies to develop follow-up protocols to assist general dental practice is warranted.
