1/3. Nonsurgical and nonextraction treatment of skeletal Class III open bite: its long-term stability.Two female patients, aged 14 years 5 months and 17 years 3 months with skeletal Class III open bite and temporomandibular dysfunction are presented. They had previously been classified as orthognathic surgical cases, involving first premolar removal. The primary treatment objective was to eliminate those skeletal and neuromuscular factors that were dominant in establishing their malocclusions. These included abnormal behavior of the tongue with short labial and lingual frenula, bilateral imbalance of chewing muscles, a partially blocked nasopharyngeal airway causing extrusion of the molars, with rotation of the mandible and narrowing of the maxillary arch. Resultant occlusal interference caused the mandible to shift to one side, which in turn produced the abnormal occlusal plane and curve of Spee. As a result, the form and function of the joints were adversely affected by the structural and functional asymmetry. These cases were treated by expanding the maxillary arch, which brought the maxilla downward and forward. The mandible moved downward and backward, with a slight increase in anterior facial height. Intruding and uprighting the posterior teeth, combined with a maxillary protraction, reconstructed the occlusal plane. A favorable perioral environment was created with widened tongue space in order to produce an adequate airway. myofunctional therapy after lingual and labial frenectomy was assisted by vigorous gum chewing during and after treatment, together with a tooth positioner. Normal nasal breathing was achieved.- - - - - - - - - - ranking = 1keywords = environment (Clic here for more details about this article) |
2/3. Inadequate implant angulation resulting from oroantral fistula: case report.Successful implant surgery is largely dependent on good treatment planning and careful surgery. A complete treatment plan must encompass both surgical and prosthetic considerations for the implant restoration. Some compromised implants are restorable, and the result can be acceptable if they can be adjusted into a more ideal position. The goals of the segmental osteotomy are the preservation of a healthy dental unit, the creation of a more ideal environment for dental restoration and occlusal reconstruction, the optimization of cost effectiveness, and the minimization of edentulous space. The purpose of this study is to present the segmental maxillary osteotomy to reposition the alveolar segment with its implant that was in a highly compromised situation.- - - - - - - - - - ranking = 1keywords = environment (Clic here for more details about this article) |
3/3. The role of orthodontics as an adjunct to periodontal therapy.In the formulation of a treatment plan for patients with advanced periodontal disease, the benefits that orhtodontics can supply must be considered. By improving the position of malposed teeth, a better environment is created for the health of the gingivae and attachment apparatus, as well as the possibility to improve osseous defects as the result of orthodontically stimulated osteogenic activity. The ultimate goal of treatment must be, in addition to control of inflammation, plaque and trauma, the creation of optimal morphologic and functional conditions which will allow these objectives to be attained. This will provide the prosthodontist and periodontist with a better chance to prolong the life of the dention.- - - - - - - - - - ranking = 1keywords = environment (Clic here for more details about this article) |
