Accidental Displacement of Third Molar into the Sublingual Space: a Case Report

Abstract

BackgroundSuccessful extraction of third molars depends on preoperative diagnosis and planning. Gold standard preoperative examinations are performed through computed tomography, decreasing risks and avoiding potential accidents. The present report highlights the value of preoperative examinations in face of accidentally displaced third molars.MethodsAn 18-years-old female patient underwent a third mandibular molar extraction with a general dentist. Accidentally, the mandibular left third molar was displaced into the sublingual space, making necessary a second surgical step. The surgery was interrupted and the patient was referred to an expert in maxillofacial surgery.ResultsAfter 21 days awaiting an asymptomatic health status, the second surgical step was successfully performed using multislice computed tomography as preoperative imaging guide.ConclusionsThe present case report highlights the clinical usefulness of imaging planning and informed consents in face of legal and ethic potential complaints.

Tomografia computadorizada de feixe cônico como exame complementar norteador em exodontia de terceiro molar semi-incluso e impactado próximo ao canal mandibular: relato de caso

“…A exodontia dos terceiros molares é um procedimento odontológico que requer indicação cirúrgica, planejamento e acompanhamento do paciente 12 . Uma de suas indicações é quando há espaço inadequado para sua erupção na região retromolar, entre o segundo molar e o ramo mandibular.…”

“…Apesar das indicações, as cirurgias de terceiros molares têm numerosas complicações, nas quais o deslocamento da raiz do dente ou do próprio dente são uma das mais perigosas 6 , e há alguns casos na literatura sobre essas ocorrências 12,13 . Outra complicação que pode ocorrer é a perfuração do seio maxilar, no caso dos terceiros molares superiores.…”

Successful Management of Ludwig’s Angina due to Dental Implant Displacement: A Rare Case Report

“…Implant-rehabilitation protocols are considered a treatment with good surgical and prosthetic predictability with high success rates [1]. Although dental implant surgery is a simple, predictable, and safe procedure, accidents and complications may occur [2]. The most frequent complications of titanium dental implant treatment are infection, implant rejection, and implant displacement.…”

Major Predictors of Late Mandibular Fracture in Third Molar Exodontia: A Review.

“…Regarding gender, men tend to have greater strength during chewing in relation to women, presenting a greater risk of mandible fracture. In patients with total dentin, the risk is even higher [6]. The degree of impaction, angulation, and volume of the third molar are also important factors.…”

“…In addition, in cases requiring extensive vestibular osteotomy, low bone mass in the mandibular basal portion, lingual teeth, and presence of associated osteolytic lesions, it is recommended to maintain a pasty diet for an extended period of time ranging from three to four weeks, according to the literature [6][7][8].…”
