Double-layered closure of chronic oroantral fistulas using a palatal rotational flap and suturing of the sinus membrane perforation: is it a successful technique?

Purpose: Chronic oroantral fistulas (OAFs) are a challenging problem in oral and maxillofacial surgery, and the treatment success rate of OAFs is as low as 67%. Thus, the double-layered closure has been described. The purpose of this study was to evaluate the simplicity and effectiveness of using a palatal rotational flap and suturing of the sinus membrane perforation as a new technique for double-layered closure.

Clinical and radiographic evaluation of implant-retained mandibular overdentures with immediate loading.

Purpose: The aim of this study was to evaluate and compare immediate-loaded implant-retained mandibular overdentures and delayed-loaded implant-retained mandibular overdentures.

Materials: Ten completely edentulous male patients received 40 dental implants. Patients were randomly divided into 2 equal groups, 5 patients each.
