Assessment of immediate clotting after flapless extraction using piezosurgery or turbine handpiece in patients receiving dual antiplatelet therapy.

Purpose: This study aimed to investigate the efficacy of piezosurgery (PI) in promoting immediate clotting after flapless extraction in patients undergoing dual antiplatelet therapy (DAPT).

Methods: In this randomized controlled trial, 80 DAPT patients were equally divided into the PI and turbine handpiece (TH) groups. Accordingly, flapless extraction of a single tooth using PI or TH was performed on each patient, and the immediate clotting status was evaluated.

[Axial split osteotomy of free fibular flap for mandibular angle reconstruction: a clinical study].

Purpose: To introduce an axial split osteotomy of free fibular flap for mandible angle reconstruction and discuss its indications and surgical technique.

Methods: 16 patients underwent axial split osteotomy of free fibular flap(12 males and 4 females, aged from 23 to 62). 11 patients with benign tumors (8 ameloblastomas and 3 odontogenic keratocyst), 3 patients with osteoradionecrosis, and 2 patients with secondary mandibular deformity were included.
