INTRODUCTION: The term oro-antral fistula is understood to mean of fistular canal covered with epithelia which may or may not be filled with granulation tissue or polyposis of the sinus mucous membrane. With the presence of a fistula the sinus is permanently open, which enables the passage of microbial flora of the oral cavity into the maxillary sinus and the occurrence of inflammation with all possible consequences. Every now and then various researchers have proposed innumerable techniques to treat this defect...

Rehabilitation of edentulous posterior maxilla with implant-supported prostheses frequently presents a challenge to dentists. This is due to insufficient bone within the region, in addition to other limiting factors such as anatomical pneumatization of the maxillary sinus. Thus, grafting of the maxillary sinus is a common procedure used to counteract these problems. Regardless of the type of biomaterial used, the success of the procedure is dependent on the formation of high-quality bone. Therefore, vascularization is a key factor for successful grafting and for the long-term maintenance of the treatment...

INTRODUCTION: Perforation of the Schneiderian membrane is the most common complication in sinus floor augmentation (SFA). When volume of grafting is qualified to prevent enlargement of the membrane perforation, lack of bone volume may occur in optimal site. CASE PRESENTATION: SFA was performed in sites #24 to 26 in a 63-year-old male. However, a 10-mm size perforation of the Schneiderian membrane occurred in site #26. Although the sinus cavity was grafted with deproteinized bovine bone mineral (DBBM) after repair of membrane perforation, insufficient bone formation was observed on palatal and distal aspects of site #26 at 5 months after SFA...

Implants have a predictable outcome and are the foremost treatment modality for prosthetic rehabilitation of edentulous patients. Due to loss of bone after extraction and pneumatization of maxillary sinus, there is insufficient bone volume for implant placement. The direct maxillary sinus lift procedure has been performed with different grafting materials (autogenous bone grafts, alloplasts, allografts, and xenografts) and without grafting material, having new bone formation around the implant. There is no evidence to prove the need for grafting material in all direct sinus lift procedures, hence the need for this review...

The aim of this study was to compare the bone resorption rate and histometry of ChronOS, a beta-tricalcium phosphate (β-TCP), mixed with autogenous bone grafts (1:1) with that of autogenous bone grafts alone in maxillary sinus elevation surgery. A total of 12 maxillary sinuses were grafted with an autogenous bone graft (control group) and 9 with ChronOS mixed with an autogenous bone graft (test group). Postoperative cone beam computed tomography (CBCT) was used to measure the initial graft volume after 15 days (T₁), and 6 months later another CBCT scan was performed to evaluate the final graft volume (T₂) and determine the graft resorption rate...

BACKGROUND: Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst. METHODS: This study was performed retrospectively on 23 patients who had sinus bone graft...

The aim of this study was to compare implant stability after maxillary sinus floor augmentation using small- or large-sized particles of Bio-Oss. Ten partially edentulous patients requiring bilateral maxillary sinus floor augmentation were enrolled. The subjects were assigned randomly to one of two experimental groups: maxillary sinus was filled with 0.25-1mm particle size (small particles) and the contralateral side was filled with 1-2mm particle size (large particles). After 8 months, a total of 25 implants were placed in the two maxillary sinuses...

INTRODUCTION: Sinonasal anatomical anomalies and inflammatory conditions may reduce success rates of maxillary sinus elevation (MSE) procedures used to allow implant placement in the atrophic posterior maxilla. Approaches combining endoscopic sinus surgery (ESS) and MSE were firstly proposed by our group and have already been described in the literature. This article aims to re-evaluate the procedure in a larger sample of patients comparing results and indications with the pertaining literature...

BACKGROUND: Skin cancers requiring nasal resection may be surgically reconstructed and/or prosthetically reconstructed. Singular surgical reconstruction may be ideal for smaller defects in which the nasal bone and cartilaginous portions of the nose are maintained, but surgical reconstruction falls short of providing acceptable aesthetic results for more extensive nasal defects. Prosthetic rehabilitation, or a combination of surgical and prosthetic rehabilitation, is more appropriate for larger defects, but prosthesis retention can be challenging when adhesives are required on adjacent mobile and secreting skin...

Introduction. The bone volume of the posterior maxilla may not be appropriate for implant placement, due to factors such as pneumatized maxillary sinus. The purpose of this study was to evaluate the percentage of graft volume reduction following sinus floor elevation (SFE), with either slow resorbable bone substitute only or a composite of slow and fast resorbable bone substitutes, using cone beam computed tomography (CBCT). Materials and Methods. In this retrospective study, CBCT scans of SFE procedures were evaluated to determine the volume of grafted sinus with either deproteinized bovine bone (DBB) or a 2 : 1 mixture of biphasic calcium sulfate (CS) and DBB, as a composite...
