Traumatic Dental Injury (TDI) is often caused by a bruise from a sports-related incident or fall. In individuals with maxillary protrusion, the risk for TDI may be higher. We treated a patient with Hereditary Gingival Fibromatosis (HGF), a rare genetic disorder characterized by proliferative fibrous overgrowth of gingival tissue, who subsequently received a TDI after periodontal surgery. A 13-y...
This report describes the treatment of a 15-year-old female patient with Angle Class I malocclusion, severe maxillary anterior crowding, maxillary midline shift to the left, and maxillary atresia associated with posterior crossbite. The treatment consisted of palatal expansion using a modified Haas expander and placement of a standard Edgewise fixed appliance. Interproximal reduction was perfor...
BACKGROUND One of the major hurdles in clinical prosthodontics has been the selection and replacement of maxillary anterior teeth in the absence of pre-extraction records. The aim of this study was to determine if a relationship exists between intraoral and extraoral facial measurements that could assist dental practitioners in selecting esthetically appropriate maxillary anterior teeth in the ...
The prevalence of hypodontia is reported to be between 1.5% to 10% in the permanent dentition. In the anterior teeth, maxillary lateral incisors and mandibular central incisors are the most frequently involved teeth. This causes esthetic problems for the patient. Several reports have focused on restoration of retained maxillary primary anterior teeth, but none have described restoration of reta...
Introduction: Apical root Resorption is a common occurrence during fixed orthodontic treatment. This study used panoramic radiographs to compare the rate of root resorption in endodontically-treated and non-endodontically-treated roots. Methods: In this descriptive-analytic study, panoramic radiographs of 20 patients aged 11-18 years with Class I Crowding and Class II Mild Skeletal malocclusio...
Introduction: Patients with dental Class II bialveolar protrusion are generally treated by extracting the four first premolars or two first and two second premolars, and retracting the anterior teeth. This case report describes the treatment of an adult patient with bialveolar protrusion, a Class II canine and molar relationship, and lip protrusion. Methods: In this patient, the maxillary right...
Midline diastema is a space between the central incisors. Although physiologic transitory maxillary midline diastema is observed in children during eruption of maxillary anterior teeth in most cases, it is self-corrected after eruption of maxillary canines. However, midline diastema unrelated to the eruption of teeth has been observed owing to various etiologic factors. Treatment to align the c...
The aims of the present study were to assess the effectiveness of skeletal anchorage for intrusion of maxillary posterior teeth, to correct open bite malocclusion, and to evaluate the usage of titanium miniplates for orthodontic anchorage. Anterior open bite is one of the most difficult malocclusions to treat orthodontically. Currently, surgical impaction of the maxillary posterior segment is c...
Bilateral en-masse distalization of maxillary posterior teeth with skeletal anchorage: a case report
OBJECTIVE The aim of this study was to introduce a new method for bilateral distal movement of the entire maxillary posterior segment. CASE REPORT A 17-year-old girl with Class I skeletal malocclusion (end-to-end molar relationships, deviated midline and space deficiency for left maxillary canine) was referred for orthodontic treatment. She did not accept maxillary first premolars extraction....
This paper describes an appliance to replace prematurely lost maxillary anterior teeth. A review of the literature is given. The prosthesis is different from previous appliances in its use of intraorally placed composite-filled celluloid crown forms. This allows for superior control of both esthetics and functional occlusal relationships. A case presentation is given describing laboratory and o...
