This case report aimed to describe the effects of leukocyte and platelet-rich fibrin (L-PRF) associated with deproteinized bovine bone mineral (DBBM) and absorbable collagen membrane (CM) on bone regeneration in maxillary sinus augmentation. A 59-year-old male patient was referred to the Department of Periodontology for implant rehabilitation of his edentulous upper jaw. The treatment plan involved maxillary sinus augmentation followed by implants installation. A split-mouth design was employed, in which the right maxillary sinus was filled using L-PRF, DBBM, and CM; the left side was filled with DBBM and CM...

Soft tissue overgrowths inside oral cavity can present with wide range of clinical manifestations and some of them can asymptomatic. Oral squamous papilloma is one of that asymptomatic lesion described in the literature with extremely low virulence and infectivity rate. Soft tissue overgrowths can sometimes interfere with denture retention. Here we report a case of squamous papilloma in a 60 years old edentulous female who presented with loss of denture retention.

Full-arch fixed implant-supported prostheses have shown high biologic success rates after long-term follow-up, along with technical and prosthetic complications. Adequate planning is necessary for immediate implant occlusal loading in a completely edentulous maxilla or mandible. For totally edentulous patients, the main prosthetic problem is the transfer of diagnostic information to the master cast when an immediate loading approach is used. The aim of this clinical case report is to illustrate a new prosthetic protocol for immediate implant loading in edentulous or potentially edentulous patients...

Insufficient crown height space, particularly in the interforaminal region of edentulous ridges with knife-edge morphology, may prevent successful prosthetic rehabilitation. Such conditions require osteoplasty, which might complicate computer-guided implant placement. This clinical report illustrates the treatment of a patient with complete edentulism rehabilitated with a mandibular implant-supported fixed dental prosthesis by using a virtually guided approach. Both alveolar ridge reduction and prosthetically driven implant insertions were computer-guided by surgical stents to increase accuracy and predictability...
