The control of postoperative bleeding represents one of the main intercurrent events associated with soft tissue surgical procedures in the oral cavity. In this context, platelet-rich fibrin (PRF) membranes are materials with great potential for optimizing soft tissue healing and induction of hemostasis. This interventional case series describes the treatment of 10 patients with excisional biopsy of benign oral cavity lesions, following a screening sequence at the surgery clinic of a Brazilian dental school between the years of 2015 and 2017...

INTRODUCTION: The aim of surgical management of benign facial skin lumps is to remove the lesion in its entirety, with minimal damage to adjacent tissue structures, while maintaining facial aesthetics. A method to achieve these goals is to remove peri-oral lesions in the labial and buccal zones via an intra-oral approach. We report an extended cases series of facial skin lumps that were excised using an intra-oral approach. METHODS: A retrospective analysis was performed on all patients who underwent excisions of benign cutaneous lesions on the face via an intra-oral approach...

Suhani Ghai, Yogesh Sharma, Neha Jain, Mrinal Satpathy, Ajay Kumar Pillai
Three-dimensional (3-D) printing is a method of manufacturing in which materials like plastic or metal are deposited onto one another in layers to produce a 3-D object. Because of the complex anatomy of craniomaxillofacial structures, full recovery of craniomaxillofacial tissues from trauma, surgeries, or congenital malformations is extremely challenging. 3-D printing of scaffolds, tissue analogs, and organs has been proposed as an exciting alternative to address some of these key challenges in craniomaxillofacial surgery...

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...
