Retrospective study of bone grafting procedures before implant placement.

Aim:The aim of this retrospective study was to evaluate morbidity and possible complications in augmentation procedures before implant placement. Methods:Records from 93 consecutive patients with indication for autogenous bone grafting before implant placement, treated at Department of Oral and Maxillofacial Surgery and Implantology of Uberlândia Federal University, in a 7-year period (July 2000 until July 2007), were reviewed. The need for bone grafting was defined by the impossibility of installing implants of adequate length or diameter to fulfill prosthetic requirements or for aesthetic reasons. Results:A total of 136 bone grafting procedures were performed. The mandibular external oblique line and ascending ramus were the most frequently used donor areas (59.64%) and block grafts (67.64%) were the most frequently used type of graft, frequently from the mandibular external oblique line/ascending ramus (52.18%). Platelet-rich plasma was used in 20.1% of all procedures, usually associated with particulate bone grafts. Maxillary procedures represented the majority of surgeries (75%), but with fewer complications compared with the mandible. Sinus mucosa perforation was the most frequent complication in maxillary procedures, whereas graft exposure was the most common complication in mandible. Conclusions:Alveolar reconstruction using autogenous bone followed by implant placement is a reliable treatment for patients with insufficient bone. Complications and morbidity were frequently observed. However, in only 6.6% of all procedures, the final rehabilitation with dental implants was not possible.

Congenital oral synechia and ankyloblepharon filiforme adnatum: Case report and literature review

INTRODUCTION Congenital intraoral synechias are adhesions of intraoral structures involving soft tissue. These conditions and another anomaly called ankyloblepharon filiforme adnatum, which is partial fusion of the eyelid margins by bands of tissue, are rarely reported in the literature. The association of both anomalies of the craniomaxillofacial region is an even more unusual finding. PURPOSE This article adds more information to the literature by reporting a case of a neonate with a rare association of bilateral synechia between the jaws, fusion of buccal mucosa to the ridges and between the tongue and palate, and ankyloblepharon filiforme adnatum in both eyes, without any other facial or systemic malformation. METHODS A literature review of similar cases published in PUBMED/MEDLINE was conducted followed by a discussion and comparison to the new case. CONCLUSION The rare association of these congenital defects, without the presence of syndromic symptoms, could be diagnosed and treated easily with good prognostic evolution.

Non-syndromic keratocystic odontogenic tumor involving the maxillary sinus: case report

INTRODUCTION: The odontogenic keratocyst tumor is rarely found in maxilla. CASE REPORT: This article describes a report of a case of a 60-year-old Caucasian female with an asymptomatic growth in the region of the posterior maxilla tumor diagnosed as odontogenic keratocyst. We discuss the diagnosis and workup for this type of injury.

A abordagem e o tratamento de um ameloblastoma unicístico na mandíbula - doi:10.5020/18061230.2006.p247

Among the complex group of odontogenic tumors, the ameloblastoma points out as the most important and common odontogenic tumor of epithelial origin. It consists mainly of a benign tumor, slow in progress and locally invasive, although it can present high rates of reincidence. The unicystic ameloblastoma is one of the tumor variants and deserves singular consideration for its peculiar characteristics. This study aimed at showing the peculiarities of this ameloblastoma variant through a case report on the care assistance of a young man committed by a jaw tumor, approaching the diagnostic methods used and the applied treatment. Based on present, we conclud that the prognostic for patients with unicystic ameloblastoma is very favorable, since the propaedeutic proceedings are well conducted by the professionals involved.
