Prevalence and Anatomical Characteristics of Bifid and Trifid Mandibular Canals: A Computer Tomography Analysis.

Purpose: To assess the prevalence and configuration of bifid (BMC) and trifid (TMC) mandibular canals using computed tomography (CT), describing the anatomical characteristics of the accessory canals, especially of the retromolar type.

Materials And Methods: CT scans of 123 patients were analysed. BMCs were identified and the patterns of bifurcation were classified, including trifid canals.

Clinical and radiographic outcomes of implants placed in extraction sites treated with alveolar ridge preservation: a 10-year retrospective analysis of a case series.

Objectives: The aim of the present study was to evaluate clinical and radiographic outcomes of implants placed in alveolar sockets treated by means of alveolar ridge preservation after 10 years of follow-up.

Method And Materials: Eleven patients treated with 11 implants placed after alveolar ridge preservation using bovine-derived xenograft particles and collagen membrane were selected. Full-mouth plaque score, full-mouth bleeding score, probing depth at four sites per implant, and radiographic marginal bone level at mesial and distal aspects for each implant were recorded at baseline and after 10 years of follow-up.
