A lateral approach to the maxillary sinus for simultaneous extraction of an ankylosed maxillary molar and sinus graft: a case report

Ankylosed tooth is defined as 'the discontinuance of normal passive tooth eruption without any mechanical barrier'.Ankylosed tooth treatment is a challenge to dental clinicians.In treatment of maxillary molar ankylosis cases there are risks of oro-antral fistula, displacement of root fragments into the maxillary sinus, as well as the necessity for providing additional sinus bone augmentation for future implant placement.In this study, we suggested a new technique using a piezoelectric device and a lateral side approach to the maxillary sinus leading to the simultaneous removal of the ankylosed maxillary molar and sinus grafting for the purpose of implant site development.
