1/837. Assessment, documentation, and treatment of a developing facial asymmetry following early childhood injury. Prepubertal trauma is often implicated as the cause of asymmetric growth of the mandible. A series of photographs taken before and after early childhood injury to the orofacial complex illustrates the development of a three-dimensional dentofacial deformity in a patient. The diagnosis and combined surgical orthodontic treatment plan to correct the facial asymmetry and malocclusion are discussed. ( info) |
2/837. A three dimensional clinical approach for anterior crossbite treatment in early mixed dentition using an Ultrablock appliance: case report. An 8-year-old girl patient presented to pediatric dentistry Department at Tufts University School of Dental medicine for orthodontic consultation. The patient was in early mixed dentition with anterior crossbite and underdeveloped posterior occlusal vertical. Anterior crossbite correction and proper posterior occlusal vertical were established in 6 months of treatment by using an Ultrablock appliance (a removable Ultrablock appliance followed by fixed Ultrablock appliance) which was designed in three dimensions (horizontal, vertical and transverse) on Denar Witzig articulator. An increase of 5 mm in the posterior occlusal vertical is reported. ( info) |
3/837. Intraoral craniofacial manipulation. This case report demonstrates how to use intraoral mechanics to correct facial planes that are not parallel, namely the eye plane, ear plane and occlusal plane. Currently, our protocol states that the cranial and occlusal planes are treated first, followed by expanding (transversely or sagittally), if necessary, the maxillary arch to accommodate the dentition. This creates the template from which the remaining treatment will be rendered, which would include, proper TMJ position, correction of mandibular facial asymmetries that result from ramus growth deficiencies, (both frontal and profile), and determining the correct posterior vertical. At this point the case is in a Class I osseous relationship with all expansion completed. The teeth are then erupted into the correct positions for the orthodontic finishing of the case. ( info) |
4/837. Treatment of a Brodie bite by lower lateral expansion: a case report and fourth year follow-up. The patient was a 4 year 4 month old boy at the first visit. The chief complaint was chewing dysfunction. The intra-oral and facial films, study casts, cephalometrics, muscle-balance monitor, temporomandibular joint radiographs were analyzed. The patient presented with a Brodie bite or unilateral posterior cross bite. The upper dental arch was wider than other children of his age. The lower dental arch was significantly smaller than the upper dental arch. The lower dental arch was expanded using a Schwarz appliance. The period of treatment was one year and two months. The period of observation was four years and ten months. First the patient underwent chewing training and secondarily then was treated by lateral expansion. After this treatment the patient achieved good occlusion and muscle function, while the morphology and function of the temporomandibular joints were improved, as well. ( info) |
5/837. The eleventh hour or where are our orthodontic limits? Case report. It is illustrated in a patient with periodontal attachment loss up to the apical root third that a combined periodontal/orthodontic approach may be beneficial even in seemingly hopeless cases. The problems of orthodontic limits and the positive effects of guided tissue regeneration are discussed. ( info) |
6/837. Florid cemento-osseous dysplasia. Report of a case. A case of florid cemento-osseous dysplasia in a 16-year-old Japanese boy is presented. The lesion was unusually large and affected all four quadrants. Progressive increase in the bulk of the lesion was seen. ( info) |
7/837. The problem of the class iii malocclusion. The etiology and treatment of Class III malocclusion has been discussed. The value of electromyographic assessment in the assessment and prediction of Class III malocclusion has been shown. ( info) |
8/837. Surgical manipulation of the occlusal plane: new concepts in geometry. rotation of the maxillomandibular complex and the consequent alteration of the occlusal plane angulation to improve functional and esthetic results have been well documented. The decision to change the occlusal plane angulation cannot be arbitrary and is made only when desired results cannot be obtained by conventional treatment planning. The geometry of rotation should be accurately planned by establishing a specific point around which the maxillomandibular complex should be rotated to achieve specific esthetic results. Treatment planning using anterior nasal spine and maxillary incisor tip as rotation points has been described and results demonstrated. This article will introduce additional points of rotation that may be considered based on a triangle constructed during treatment planning. Two clinical examples are presented in which these types of rotation were implemented. ( info) |
9/837. Occlusal rehabilitation using implants for orthodontic anchorage. osseointegration is defined as a direct interaction of bone to an implant surface. As a result, the implant fixture is immobilized in the bone and lends itself to function as an anchor for orthodontic tooth movements. When properly treatment-planned, these implants can also be used as prosthodontic abutments for single crowns, or removable or fixed partial dentures. This article describes how implant fixtures were surgically placed within the maxillary and mandibular arches of a partially edentulous patient, and used for orthodontic anchorage to reposition the remaining teeth into a more favorable arch position, creating increased posterior interocclusal space. The fixtures were then restored with fixed partial dentures to rehabilitate the patient into a mutually protected occlusion. ( info) |
10/837. Dental and craniofacial features of Aarskog syndrome: report of a case and review of literature. Aarskog syndrome is a rare syndrome with a typical triad of facial, digital and genital characteristics. The characteristic cephalometric finding in this patient was the unusually large upward slant of SN plane and a steep Ba-N plane. Though the patient presented with a class I skeletal pattern, both the maxilla and mandible were hypoplastic and retruded with respect to the cranial base. Other characteristic features regarding the mandibular morphology were a large FMA (37 degrees) and Sn-GoGn (44 degrees) angles, a large gonial angle (138 degrees), an increase in total anterior facial and lower anterior facial height.
