1/15. Molarization of the lower second premolars.This paper presents a case of extreme tooth variation. The patient was first observed during the mixed dentition period, when she presented a mild Class II malocclusion with increased overjet and acceptable overbite. In a panoramic radiograph, the presence of lower second premolars of disproportionate dimensions was discovered. When these oversized premolars erupted, the Class I malocclusion tended toward Class III, with an edge-to-edge bite. This created an unstable occlusion and the possible need for extractions.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
2/15. Sliding plates on complete dentures as a treatment of temporomandibular disorder: a case report.This work presents a case report of a woman, aged 62, who presented with signs and symptoms of temporomandibular disorder (TMD). The patient reported pain in the masticatory system and examination showed a reduction in the occlusal vertical dimension (OVD). She was treated with complete dentures incorporating a modification to the posterior regions developed by the authors and which were termed "sliding plates." Through analysis of photographs taken of the patient prior to the extraction of the patient's natural dentition, sliding plates were utilized to reestablish the OVD. The sliding plates also allowed for unrestricted eccentric mandibular movements, thereby accelerating the neuromuscular deprogramming and making it possible for the mandible to adopt a more physiologic position. The dentures reduced the pain and were well-accepted by the patient. Therefore, sliding plates may be of great benefit to completely edentulous patients with painful symptoms that result from alterations in the OVD and inappropriate condylar positioning.- - - - - - - - - - ranking = 52.921931629068keywords = mandible (Clic here for more details about this article) |
3/15. 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 = 158.7657948872keywords = mandible (Clic here for more details about this article) |
4/15. Locating the centric relation prematurity with a computerized occlusal analysis system.Locating the first tooth contact that interferes with freedom of movement in and out of centric relation has been the diagnostic and treatment objective of most occlusal therapies. The centric relation prematurity can be located by various methods, which involve operator-guided mandibular positioning combined with the patient's subjective assessment of his or her perceived first tooth contact. The method known as bimanual manipulation has been widely recognized and accepted as a predictable method of determining and verifying the centric relation position. The first occlusal contact that results when the mandible is closed on a correct centric relation axis is known as the centric relation prematurity. An alternative procedure combines bimanual manipulation with the simultaneous recording of the sequence of resultant tooth contacts using a computerized occlusal analysis system. This alternative offers a significant improvement in the precision of locating the first tooth contact. This article describes a method of identifying the first tooth contact while not relying on the patient's subjective assessment of his or her perceived occlusal feel.- - - - - - - - - - ranking = 52.921931629068keywords = mandible (Clic here for more details about this article) |
5/15. Maxillary bone growth and implant positioning in a young patient: a case report.The literature supports the efficacy of osseointegrated implants for partially edentulous patients, but care must be exercised in adolescents with incomplete bone formation. Implants do not follow the normal growth of the jaws, and they behave like ankylosed teeth. They may also interfere with the normal growth of the alveolar process and jeopardize the germs of the adjacent permanent teeth or alter eruption. This case report analyzes the unfavorable clinical and radiographic findings of a single-tooth replacement in a young male over a 15-year period.- - - - - - - - - - ranking = 4.1020894970414keywords = jaw (Clic here for more details about this article) |
6/15. TMJ fractures in children and adolescents: treatment guidelines.TMJ fractures must be focused not only as a cause of direct damage to osseous structures, but also of future disturbances of dentofacial development. Treatment is aimed at restoring normal joint function, occlusion and symmetry. Any disturbance of condylar cartilage will result in alteration of mandibular development. The subsequent deformity of jaw and face will depend not only on the type, intensity extent and chronology of the noxious agent, but also on the particular time of occurrence and growth activity. Thus the effect will be more decided if the disturbance occurs early in life, during childhood, when growth activity is greater and mandibular shape and size have not been assumed yet. This report will include basic information on both prevention and first aid in these types of injuries. The correct application of these precautions immediately following the trauma should improve the short and long-term outcome. Information on diagnosis and treatment of lesions of the bone and soft tissues, which may coexist with dental trauma, a critical first step in the overall management of traumatized patients, will be given. Follow-up procedures of these patients will be illustrated. The guidelines described in this paper for the treatment of traumatic TMJ fractures in children and youths are based on our clinical experience. They are intended as an aid to practioners in the management and treatment of these traumas, by professional must always use professional judgement. There are no guarantees of any positive results associated with the use of these guidelines, although it is felt that time and proper treatment will maximize the chances of success.- - - - - - - - - - ranking = 4.1020894970414keywords = jaw (Clic here for more details about this article) |
7/15. Orofacial complications associated with forward repositioning of the mandible in snore guard users.snoring and obstructive sleep apnea (OSA) result from a collapse of the tongue, soft palate, and pharynx, causing temporary airway blockage. Acrylic mandibular advancement splints and Herbst appliances are used to relieve snoring and mild OSA. Repositioning the mandible forward may have an adverse effect on the orofacial and dentoalveolar structures of susceptible individuals. This article reports two cases in which orofacial complications developed following the utilization of snore guard appliances.- - - - - - - - - - ranking = 264.60965814534keywords = mandible (Clic here for more details about this article) |
8/15. Talon cusp: report of a case.Talon cusp is a developmental dental anomaly, normally located on the palatal surface of the anterior teeth, that can occur in both primary and permanent dentition. The aim of this article is to relate a clinical case of talon cusp that interfered with both the occlusion and appearance of the patient. During anamnesis, the patient told of difficulty masticating. Clinical examination revealed labial inclination of the maxillary central incisors, featuring an overjet of about 5 mm, with interposition of the lower lip and an Angle Class I occlusal relationship. A treatment plan was devised in which gradual grinding of both talon cusps, the fitting of a removable orthodontic device, and clinical and radiographic follow-up were carried out.- - - - - - - - - - ranking = 0.2keywords = lower (Clic here for more details about this article) |
9/15. orthognathic surgery for occlusal reconstruction of old malunited jaw fracture.Old malunited jaw fractures of nine patients who underwent orthognathic surgery for occlusal reconstruction were clinically evaluated. Early surgery on fractures of the jaw is the optimal treatment when due attention must be paid to occlusion. Since occlusal revision surgery subsequent to inaccurate diagnosis and inappropriate surgery is certainly very difficult and often unsuccessful, surgeons need to pay special attention to this situation.- - - - - - - - - - ranking = 24.612536982249keywords = jaw (Clic here for more details about this article) |
10/15. Resin-bonded palatal stops for the management of a deep traumatic overbite--a case report.This case presents a novel application of adhesive technology to treat a deep traumatic overbite in a patient unable to tolerate a removable appliance. Cast metal shelves were bonded into palatal surfaces of the upper anterior teeth. Three lower incisors required post crowns which were proclined slightly to engage the palatal stops of the upper teeth. After 24 months the palatal stops were firm and the occlusion seemed stable.- - - - - - - - - - ranking = 0.2keywords = lower (Clic here for more details about this article) |
