Retained Third Molars Removal in a Severely Resorbed Edentulous Mandible. A Case Report

Management of an Imminent Pathological Fracture of a Fibular Neomandible Via a Minimally Invasive Approach-A Case Report

Fibular free flap reconstruction remains the workhorse of postmandibulectomy reconstruction. Dental implantation to support a dental prosthesis is a sought-after outcome when the area of resection involves tooth-bearing zones. Chronic perisoft tissue pedicle hyperplasia with secondary infection leading to gradual bone loss is a simple complication to manage in the general population, but it becomes a serious issue in the fibula mandibular reconstruction patient in that it can lead to pathological fracture of the fibula. A case of a patient with a near fracture of his fibula mandibular reconstruction, and its management via a minimally invasive approach is presented.

The ability of orthodontists and oral/maxillofacial surgeons to predict eruption of lower third molar

Background

The aim of this study was to evaluate the ability of oral/maxillofacial surgeons (OMFSs) and orthodontists to predict third molar eruption by examining a simple panoramic radiograph in cases where full spontaneous eruption occurred.

Methods

Panoramic radiographs of 17 patients, 13–16 years of age, were obtained just after orthodontic treatment (T1), when the third molars were intraosseous. The radiographs at T1 were presented to 28 OMFSs and 28 orthodontists—who were asked to give a prognosis for the lower third molars on both sides (n = 34). The full spontaneous eruption of all third molars was clinically observed when patients were older than 18 years (T2). These teeth were clinically asymptomatic at T1 and T2.

Results

OMFSs decided by extractions in 49.6 % of cases while orthodontists in 37.8 % (p < 0.001), when the radiographs were examined at T1. Agreement between OMFSs and orthodontists was excellent (Kappa = 0.76, p < 0.0001), as well as intragroup agreement for both OMFSs (Kappa = 0.83) and orthodontists (Kappa = 0.96).

Conclusions

Despite a remarkable agreement for third molar prognosis, orthodontists and OMFSs were unable to predict lower third molar eruption by examining a simple panoramic radiograph. Both indicated extractions of a considerable number of spontaneously erupted asymptomatic teeth.
