Abstract

Teeth displacement during extractions even tough rare are extremely unwanted, especially for infra temporal space. This accident generally necessitate additional treatment for their resolution, being either immediate or late. Several authors discribed surgical techniques for removal displaced teeth into the infratemporal space, varying according to the degree of displacement, being that in some of this cases, is necessary the utilization of complementary tools. This case describes the technique utilized for late removal of tooth 18 (upper right third molar) dislocated into the lower portion of the infratemporal space (confirmed by the Cone Bean Computer tomography Scan), exam was performed after the patient reported pain in the operated region and during mandibular movement too, with an interincisal opening maximum of 20 millimeters. The procedure was realized under local anesthesia by a conservative intraoral approach and aid of intermaxillary fixation screw to facilitate extraction. The patient recovered well, without complications, with remission of pain and restoration of mouth opening.

Highlights

Despite advances in surgical techniques and professional qualification, complications in dentoalveolar surgeries are possible in several stages of the procedure, especially in extraction of third molars

Summary

Introduction

Despite advances in surgical techniques and professional qualification, complications in dentoalveolar surgeries are possible in several stages of the procedure, especially in extraction of third molars. Accidents during third molar extraction and complications postoperative are unwanted events that may demand additional treatment for their resolution (Agarwal P et al, 2019) Among this events are, for example, bone fractures, alveolar osteitis, hemorrhage, infecctions, nerve injuries and not so common the dental dislocations (Nardo DD et al, 2019). The tooth may migrate into a lower position after an expectant treatment has been instituted and may be removed by an extended third molar approach or by direct incision on the dislocated dental element (Sverzut CE et al, 2009). (Orr DL II, 2019; Battisti A et al, 2019; Sencimen M et al, 2017) The purpose of this case report is to demonstrate the technique used for the late removal of a right upper third molar that was displaced into the lower portion of the infratemporal region
