Etiological factors for mandibular fractures in transoperative period of tooth extraction: systematic review

Abstract

Objectives: to analyze the possible etiological factors associated with mandibular fractures occurring during tooth extractions. Methods the following data were collected: sex, age, the extracted tooth, tooth classification, angulation, level of bone impaction, pathological association, recognized technical errors, instruments used at the time of the fracture, and the surgeon’s experience and specialization, if applicable. An electronic search of the following databases was performed: PubMed/Medline, Lilacs, Embase, and Scopus. The data were tabulated and analyzed using the Chi-square test, a P-value less than 0.05 was considered significant. Results: a total of 80 cases were selected. Sex and age were not statistically significant (P>0.05). The teeth most associated with fractures were the mandibular third molars; however, the location was not significant. Pell & Gregory classes II, B, C, mesio-angular teeth, partial bone impaction, teeth related to pathological process, application of excessive strength, extractions with elevators, and non-specialists showed greater association with mandibular fractures during transoperative time (P<0.05).

Iatrogenic Fracture of the Lower Jaw: A Rare Complication of Lower Molar Extraction

“…As the average length of the handle is 90 mm and the average length of the working end is 8-9 mm, the force applied at the working side is approximately 10 times higher. As evidenced by examples from clinical practice and also by a number of studies published on this topic, the mechanically weakened area of the mandible angle may not always withstand the action of such a force (30,31). Mandible fracture risk factors include age over 37 years, the presence of bone pathological lesions, tooth impaction, and the high ratio of tooth height in relation to the remaining bone height (9).…”

Complicações associadas à extração dos terceiros molares inclusos: revisão de literatura / Complications associated with the removal of unerupted third molars: literature review

“…Na literatura consultada, ainda que de forma escassa também é citada a técnica de coronectomia como alternativa para exodontia do 3M inferior ((MASCARENHAS et al, 2020;RODRIGUES et al, 2020;SILVA et al, 2018). Segundo Silva et al (2020) A fratura mandibular é uma complicação rara, contudo, pode evoluir para um quadro sério, caso não seja tratada de forma adequada (BONARDI et al, 2020;LIMA et al, 2017). Segundo Lima et al (2020)…”

“…Os terceiros molares apresentam maior incidência de inclusão pois não irromperam no período fisiológico adequado, em alguns casos, pode ainda estar impacto devido a algum tipo de obstrução (ARABION et al, 2017;MATOS et al, 2017;OLIVEIRA et al, 2016) vida do paciente pois impossibilita o processo de mastigação (BONARDI et al, 2020).…”

“…Comumente progride para um quadro infecioso que se não for tratado em tempo hábil, pode causar dor, inchaço e trismo. Para seu tratamento há a necessidade de internação hospitalar sob anestesia geral para o acesso cirúrgico (BONARDI et al, 2020;LIMA et al, 2017).…”
