INTRODUCTION Patients with dentofacial deformities may undergo orthodontic or orthodontic-surgical treatment. Both modalities can affect esthetics. OBJECTIVE This study aims to evaluate clinical and radiographic changes in exposure of maxillary central incisors occurring after orthognathic surgery for maxillary advancement. METHODS A total of 17 patients who underwent orthognathic surgery f...

Introduction: The replacement of congenitally missing maxillary lateral incisors can be a challenge from both a restorative and surgical perspective. The restorative dentist is limited in achieving esthetics by the surgical result not only by the implant position but by the surrounding periodontium of the site itself, as well as the adjacent teeth. The present case, replacing congenitally missi...

Hypondontia is identified as a phylogenetic reduction of teeth number more often affecting the permanent than deciduous dentition. The studies of several authors have reported that the upper lateral incisors are most frequently affected by hypodontia, followed by the upper and lower second premolars (1, 2, 3, 5, 6). From genetic point of view, hypodontia is determined as an autosomal-dominant e...

BACKGROUND Rehabilitation using an implant supported overdenture with two implants inserted in the interforaminal region is the easiest and currently accepted treatment modality to increase prosthetic stabilization and patient satisfaction in edentulous patients. The insertion of implants to the weakend mandibular bone decreases the strength of the bone and may lead to fractures either during o...

The purpose of this study was to determine the severity of gingival margin discrepancy affecting the mandibular incisors in children with a single-tooth anterior crossbite. The response of the position of the gingival margin to correction of the crossbite also was investigated. Twenty-two subjects with a single central crossbite and 16 subjects with a single lateral crossbite were identified fr...

OBJECTIVE The aim of this study was to determine the optimal loading conditions for pure intrusion of the six maxillary anterior teeth with miniscrews according to alveolar bone loss. METHODS A three-dimensional finite element model was created for a segment of the six anterior teeth, and the positions of the miniscrews and hooks were varied after setting the alveolar bone loss to 0, 2, or 4 ...

OBJECTIVE To verify, via CBCT, the existence of a definable distance for bodily intrusion of maxillary incisors, and its correlation to age, sex and/or facial biotype. MATERIALS AND METHODS The sample consisted of sagittal sections obtained from 79 CBCTs of 220 maxillary incisors correctly aligned on their osseous base (maxillary plane/long axis between 105° and 115°). The same sagittal secti...

Palato gingival grooves, also called palatoradicular grooves or radicular lingual grooves are developmental anomalies in which an infolding of the inner enamel epithelium and Hertwig’s epithelial root sheath create a groove that passes from the cingulam and extend varying distances apically on to the root. The purpose of this study was to determine the prevalence of palato gingival groove in ma...

OBJECTIVE To test the null hypothesis that there are no correlations between the morphology of the upper jaw, the position of the upper incisors, and facial type. MATERIALS AND METHODS From a sample of 191 patients, the FMA angle was used to select 20 short face type, 20 norm face type, and 20 long face type patients, aged 12 to 40 years. Using cone-beam computed tomography (CBCT), tomography...

Purpose: The aim of the study was to determine whether fixed orthodontic appliances cause root and alveolar bone resorption and to compare the precision of orthopantomography and computerized tomography in detection of resorption process. Methods: Eighty-five patients scheduled for orthodontic therapy with fixed appliances were included in prospective self-controlled study. Before and after ort...
