- Abstract
- Background: Maxillary tuberosity fractures during molar teeth extraction commonly occur in dental practice; however, very few cases have been reported and discussed in the literature. A correct preoperative radiographic interpretation, coupled with the anatomical knowledge of the structures involved, is essential to prevent such complications. Aim: The purpose of this paper is to enumerate the predisposing and etiological factors of maxillary tuberosity fractures during the extraction of upper molars, discuss the procedures that need to be taken when small or large fractured fragments of the tuberosity are evident during surgery, and suggest appropriate recommendations. This study is based on a thorough literature review. Conclusions: Upon discovering that a maxillary tuberosity has fractured, the dentist must first halt the procedure before inadvertent laceration of the adjoining soft tissue occurs and then determine the extent of the fracture by palpating the mobile fragment. After performing the dissection of the soft tissues, immediate removal of the small fractures, including the tooth with small bony fragments, may be the best option, because of the difficulty incurred when attempting to retain the bone. When a large bony fragment is present, it is recommended (i) that the extraction be abandoned and surgical removal of the tooth be performed using root sectioning, (ii) that the dentist tries to detach the fractured tuberosity from the roots, or (iii) that the dentist stabilizes the mobile part(s) of the bone by means of a rigid fixation technique for 4-6 weeks and, at a future moment, attempts a surgical removal without the use of a forceps.
