1/29. 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 = bite (Clic here for more details about this article) |
2/29. Form follows function: occlusion based rationale for esthetic dentistry.Esthetic dentistry is one of the prime essential areas in dentistry today. The purpose of this article is to address the dependent relationship between excellent esthetics and optimum occlusion. Occlusal objectives must be addressed and achieved. If one is to expect to recreate ideal esthetics, one must first thoroughly investigate, diagnose, and establish an ideal occlusal scheme. The case study within this article revisits the most imperative principle with regards to esthetics and that is: form always follows function.- - - - - - - - - - ranking = 0.07982883602298keywords = relation (Clic here for more details about this article) |
3/29. 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 = 2.5keywords = bite (Clic here for more details about this article) |
4/29. Restoring esthetics and anterior guidance in worn anterior teeth. A conservative multidisciplinary approach.BACKGROUND: Developments in adhesive dentistry have given the dental profession new restorative materials and technology to restore esthetics and function to the worn anterior dentition. This article illustrates, through a clinical case study, the clinical requirements for restoring esthetic harmony and functional stability to the worn anterior dentition. CASE DESCRIPTION: The author presents the case of a 24-year-old man who sought esthetic dental treatment because he was unhappy with the appearance of his maxillary anterior teeth. The review of his dental history revealed that he ground his teeth at night. The author performed a complete evaluation of the causes of the patient's bruxism and created a diagnostic preview to, among other things, develop the relationship between the condylar and anterior guidance and to establish the esthetic requirements for the final restorations. Treatment included periodontal recontouring, tooth preparation and placement of temporary and then permanent restorations; the patient also was given an occlusal guard to protect the restorations against future bruxing. CLINICAL IMPLICATIONS: Whatever the cause of occlusal instability, it is important that the restorative dentist be able to recognize its signs--such as tooth hypermobility, tooth wear, periodontal breakdown, occlusal dimpling, stress fractures, exostosis, muscle enlargement and loss of posterior disclusion. When restoring the worn dentition, the clinician should bear in mind the five P's: proper planning prevents poor performance.- - - - - - - - - - ranking = 0.07982883602298keywords = relation (Clic here for more details about this article) |
5/29. An unusual case of furcation external resorption.AIM: To describe the presentation and management of an unusual external root resorption. SUMMARY: An unusual external inflammatory root resorption presented in the furcation of a mandibular first molar. review of earlier radiographs suggested that the lesion was non-progressive. Occlusal trauma associated with anterior open bite was the most likely aetiological factor. No active treatment was prescribed. KEY learning POINTS: External resorption may occur following loss of the external root surface. Occlusal trauma may be a propagating stimulus for progressive resorption. Lesions may sometimes be non-progressive, and treatment may therefore be more damaging than observation.- - - - - - - - - - ranking = 0.5keywords = bite (Clic here for more details about this article) |
6/29. Peri-implant bone loss: management of a patient.This clinical report presents the prosthodontic management of early peri-implant bone loss in a partially edentulous patient. Two narrow Branemark implants (3.3 mm in diameter) were placed to retain a mandibular implant prosthesis in the area of the mandibular left second premolar and first molar. Two weeks after the prosthesis was put into function, the distal implant exhibited soft tissue reactions. Radiographically, bone corresponding to 4 threads and 7 threads was lost at the mesial and distal sites, respectively. After occlusal load reduction was made to the existing prosthesis, bone was observed to have regenerated sufficiently to restore the defect radiographically, though not to the original level. The bone remained at a similar level at 36 months after treatment.- - - - - - - - - - ranking = 0.5keywords = bite (Clic here for more details about this article) |
7/29. 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 = 0.71845952420682keywords = relation (Clic here for more details about this article) |
8/29. Occlusal rehabilitation of a patient with hereditary multicentric osteolysis.This article describes the fixed prosthodontic rehabilitation of a 53-year-old male patient with multicentric osteolysis. Before treatment, the patient exhibited signs and symptoms of temporomandibular disorder and had recurrent tension-type headaches and pain in the neck and shoulder area. One of his chief complaints was frequent fracture of restorations. After extensive occlusal rehabilitation, occurrence of headache and pain ceased, and other signs and symptoms of TMD diminished. The long-term prognosis depends on the stage of the genetic disorder, which cannot be determined.- - - - - - - - - - ranking = 0.5keywords = bite (Clic here for more details about this article) |
9/29. 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 = 0.035682962942992keywords = jaw (Clic here for more details about this article) |
10/29. 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 = 0.035682962942992keywords = jaw (Clic here for more details about this article) |
