ABSTRACT
The presence of asymptomatic third molars can represent a potential problem in the mandible when these teeth are retained and the patient has lost all normally erupted teeth. Once the mandibular first and second molars are removed, the mandibular body becomes weaker with time, increasing the complexity, morbidity and incidence of complication in the surgical procedure to remove the retained third molar. This paper reports a case where the mandibular third molars retained in a severely resorbed mandible were removed in a 54-year-old female patient. The treatment plan was based on the safe surgical removal of the teeth and prosthetic rehabilitation with an implant-supported milled bar overdenture and a bone-mucous-supported complete denture in the mandibular and maxillary arch, respectively. If the removal of a retained third molar is indicated in a severely resorbed edentulous mandible, the treatment plan must involve not only preventive measures in order to avoid mandible fracture during or after tooth removal, but also alternatives that allow an adequate mandibular rehabilitation.
RESUMO
A presença de terceiros molares inclusos assintomáticos pode representar um grande problema quando estes dentes encontram-se inclusos em um paciente desdentado total. Uma vez que os primeiros e segundos molares foram extraídos, o corpo mandibular torna-se mais frágil com o passar do tempo, o que aumenta a complexidade, a morbidade e a incidência de complicações nas cirurgias de remoção de terceiros molares inclusos. Neste artigo é apresentado um caso de uma paciente de 54 anos de idade com severa reabsorção do osso mandibular onde os terceiros molares mandibulares encontravam-se inclusos e com necessidade de extração. O plano de tratamento objetivou a extração segura dos dentes e a reabilitação mandibular com o uso de uma prótese implanto-suportada. Se a extração dos terceiros molares inclusos é indicada em pacientes que apresentam mandíbula atrófica, o plano de tratamento deve incluir não apenas as medidas preventivas com o intuito de prevenir a fratura da mandíbula durante ou após a remoção dos dentes, mas também alternativas de tratamento que possibilitem uma adequada reabilitação.
