Sinus floor augmentation (SFA) is one of the techniques that has been proposed for improving the long-term retention of dental implants. The procedure involves the creation of a submucoperiosteal pocket in the floor of the maxillary sinus for placement of a graft consisting of autogenous, allogenic, or alloplastic material. Complications of the SFA predominantly consist of disturbed wound heali...

Introduction. This paper describes a case of bone augmentation with combination of Platelet-Rich Fibrin (PRF) and β-TCP for treatment of chronic periapical cyst. The case was followed for 12 months. Methods. Patient presented with chronic periapical lesion in maxillary anterior teeth with history of trauma 8 years back. Radiographically, a periapical cyst was seen in relation to maxillary left ...

OBJECTIVE Cleft lip and palate is a congenital facial malformation with an established treatment protocol. Mixed dentition period is the best moment for correct maxillary bone defect with an alveoloplasty. The aim of this surgical procedure is to facilitate dental eruption, re-establish maxillary arch, close any oro-nasal communication, give support to nasal ala, and in some cases allow dental ...

STATEMENT OF PROBLEM Load transfer mechanisms and possible failure of osseointegrated implants are affected by implant shape, geometrical and mechanical properties of the site of placement, as well as crestal bone resorption. Suitable estimation of such effects allows for correct design of implant features. PURPOSE The purpose of this study was to analyze the influence of implant diameter and...

PURPOSE The aim of this study was to evaluate the bone repair process in the maxillary sinus in monkeys treated with high-density porous polyethylene (Medpor) METHODS Four capuchin monkeys (Cebus apella) were submitted to bilateral horizontal osteotomies in the anterior wall of the maxillary sinus and divided into 2 groups: control group, left side with no implants, and porous polyethylene gr...

Introduction: The aim of this study was to perform a systematic review and meta-analysis to compare the effect of bone-borne expansion (BBE) and tooth-borne expansion (TBE) in patients with maxillary constriction. Methods: Electronic databases, including MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials, were searched up to February 2019. Elig...

Bone loss in the oral and maxillofacial region caused by trauma, tumors, congenital disorders, or degenerative diseases is a health care problem worldwide. To restore (reconstruct) these bone defects, human or animal bone grafts or alloplastic (synthetic) materials have been used. However, several disadvantages are associated with bone graft transplantation, such as limited bone volume, donor-s...

BACKGROUND We present a case report of a professional diver who sustained a fracture of the left orbital medial wall as well as floor exceeding 50% with orbital fat herniation blocking the maxillary sinus ostium. This may result in a closed cavity within the maxillary sinus that could potentially result in barotraumas during future diving. The aim of his surgery consists of repairing the orbita...

PURPOSE To investigate the healing pattern of the mucous membrane after tooth extraction necessitated by periodontal disease in the maxillary sinus. METHODS One hundred and three patients with 119 maxillary sinuses were investigated. Before implant placement, cone-beam computed tomography (CT) scanning was performed. The causes of extraction, the time elapsed since extraction, smoking, period...
