Abstract

Study design: prospective and descriptive case – series.

Objective: to analyze outcomes, and complications of sagittal split osteotomy (SSO) for removal of deeply impacted third mandibular molars.

Methods: 8 subjects with deeply impacted third mandibular molars with an intimate relationship between the inferior alveolar nerve (IAN) and the dental roots were included. All subjects were treated with SSO to remove the deeply impacted third molar. The outcomes were evaluated at 3, 6 and 12 months after surgery, clinically and radiographically. 

Outcomes: 6 subjects (75 %) had transient neurosensory disturbance (ND), with full recovery between 6 and 12 months. 2 patients (25%) had a non-disabling hypoesthesia at 12 months of follow up. It was necessary to remove the osteosynthesis material due to infection in one patient (12.5%). No other complication was observed. Radiographic signs of bone healing were evident at 6 months after surgery, without bone grafting materials.

Conclusions: SSO is a safe method for removing deeply impacted third mandibular molars and associated lesions. Nevertheless, additional studies with a larger sample are necessary to confirm these results
