BACKGROUND: Dental implant-supported restorations have long been used as a successful modality for replacing missing teeth. There are two well-established methods of implant placement. The traditional approach to implant surgery involves raising a mucoperiosteal flap and the alternative approach does not involve reflecting a flap, each having its own advantages and disadvantages. The purpose of the present study was to compare and evaluate the soft and hard tissue changes around endosseous implants placed using flap and flapless surgery in mandibular posterior edentulous sites over a period of time...

Bisphosphonate-induced osteonecrosis of the jaw [BIONJ] is a relatively new pathological condition which was first described in the year 2003. The prevalence of BIONJ in patients on oral formulations is around 0.05% within the first 3 years and increases up to 0.2% after 4 years of consumption. Proven systemic risk factors like anemia, uncontrolled diabetes, corticosteroid therapy, and chemotherapy in neoplastic diseases [e.g., high doses of methotrexate up to 30 mg daily] significantly increase the chances of acquiring BIONJ...

CONTEXT: Cranioplasty is a frequently performed procedure that uses a variety of reconstruction materials and techniques. In this technical note, we present refinements of computer-aided design-computer-aided manufacturing inlay cranioplasty. OBJECTIVE, DESIGN, AND SETTING: In an attempt to decrease complications related to polyether-ether-ketone (PEEK) cranioplasty, we gradually made changes to implant design and cranioplasty techniques. These changes include under-contouring of the implant and the use of segmented plates for large defects, microplate fixation for small temporal defects, temporal shell implants to reconstruct the temporalis muscle, and perforations to facilitate the drainage of blood and cerebrospinal fluid and serve as fixation points...
