1/12. Occlusal reconstruction of a collapsed bite by orthodontic treatment, pre-prosthetic surgery and implant supported prostheses. A case report.The loss of mandibular molars can result in a 'collapsed bite' owing to tilting of teeth adjacent to the gap and overeruption of maxillary molar segments. The lost interarch and interdental space must be regained before prosthetic reconstruction. This case report documents the treatment of a patient by orthodontic, surgical and prosthetic means. The teeth were orthodontically aligned to meet predetermined surgical and prosthetic requirements. The surgical phase comprised a posterior segmental maxillary osteotomy and one-stage placement of three large-diameter implants in the mandible. Finally, the occlusion was restored with mandibular implant-supported prostheses.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/12. Complications with intermaxillary fixation screws in the management of fractured mandibles.A dedicated bicortical bone screw for temporary intraoperative intermaxillary fixation (IMF) during open reduction and fixation of mandibular fractures offers many benefits to surgeons and patients. We have used this system for 2 years and confirm the benefits over traditional methods of intermaxillary fixation. However, complications can arise. One hundred and twenty-two patients with mandibular fractures had IMF screws of which five (4%) developed complications intraoperatively and postoperatively. Complications included fracture of the screws on insertion, iatrogenic damage to teeth causing loss and bony sequestra around the area of screw placement.- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
3/12. transplantation of a lower bicuspid after traumatic loss of three upper incisors.BACKGROUND: Prosthodontic and orthodontic procedures have been described for the treatment of patients with traumatic loss of teeth. PATIENT AND methods: Both upper central incisors and the upper right lateral incisor had to be extracted in an 8-year-old patient after failure of conservative procedures following a sports accident. The patient was treated on a temporary basis with a space retainer as a substitute for the teeth. Definitive therapy was carried out by transplanting a lower bicuspid germ into the upper arch with subsequent orthodontic gap closure. RESULTS: 8 years after the intervention, the transplanted tooth is still in place. The patient is fully rehabilitated both functionally and esthetically with no discomfort. CONCLUSIONS: The transplantation of bicuspid germs in conjunction with orthodontic gap closure is a valuable alternative to prosthodontic treatment, particularly in the case of loss or aplasia of several teeth.- - - - - - - - - - ranking = 0.01141031474041keywords = lower (Clic here for more details about this article) |
4/12. dental implants in a young patient with Papillon-Lefevre syndrome: a case report.A case is reported of dental implant placement in a 13-year-old patient diagnosed with Papillon-Lefevre syndrome. Two titanium dental implants were placed in the mandible for an implant-retained denture after the patient complained of having an unstable prosthesis. Follow-up radiographs showed successful osseointegration and preservation of alveolar bone 1 year after implant placement and the continual wearing of a functional dental prosthesis.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
5/12. Removable prostheses for preschool children: report of two cases.Dental prostheses are frequently used to avoid psychologic, speech, or swallowing problems in preschool children with considerable tooth loss. Two cases of preschool children are presented, involving multiple loss of primary teeth. The purpose of this study was to promote the correct development of the maxilla and mandible by using removable dental prostheses and to guide the eruption of the permanent molars. Removable acrylic prostheses were provided for two children, with a special metallic s-shaped handle (ansa), which guided the eruption of the first permanent molars. These prostheses were modified as the children grew. By replacing missing teeth, several oral functions were re-established, development of the maxilla and mandible was promoted, and each child could develop socially from a psychologic point of view. The use of removable dental prostheses in preschool-aged children presenting with considerable tooth loss can be a viable and successful treatment option.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
6/12. Localized edentulous ridge augmentation with upside down osteotomy prior to implant placement.Localized bone defects may be seen following the extraction of teeth with periapical lesion or advanced periodontal disease, or as a result of trauma. When these regions are considered for treatment with implants, localized ridge augmentation will be necessary. Autogenous bone grafts are used exclusively for ridge augmentation. This case report represents the treatment of a localized edentulous ridge with an upside down osteotomy technique at the symphysis region prior to implant placement. Systemically healthy 21-year-old female patient, who was missing a lower right incisor tooth, was scheduled for an implant treatment. However, the crestal width was only 1 mm. The augmentation was planned and the region was treated with an upside down osteotomy technique. Nine months after the augmentation procedure, the computed tomography (CT) examination of the area revealed that the width of the crest was 7 mm, and the height of the crest was in good relation with the cementoenamel junction of the adjacent teeth. Flipping a bone block graft, which was harvested from the edentulous area, upside down may provide a successful result in partially edentulous ridges, in both maxilla and mandible.- - - - - - - - - - ranking = 1.0022820629481keywords = mandible, lower (Clic here for more details about this article) |
7/12. Utilization of third molars in the orthodontic treatment of skeletal class III subjects with severe lateral deviation: case report.AIM: This clinical report discusses the importance and use of third molars in the adult patient by presenting a case in which their use during orthodontic treatment allowed occlusal improvement. SUBJECT AND TREATMENT PLAN: The patient was a Japanese adolescent boy who had a skeletal Class III malocclusion with severe lateral deviation of the mandible, significant loss of posterior occlusal vertical dimension, due to premature loss of the maxillary and mandibular left first molars, and furthermore, both first molars had advanced carious lesions that had resulted in reduced crown heights and bilateral chewing surfaces. The mandible had shifted to the left, with a bilateral chewing pattern and a lack of posterior vertical alveolar height, which in turn had produced an abnormal occlusal plane and curve of Spee. The maxillary arch was expanded, the maxilla was moved downward and forward, and the mandible was moved slightly backward and rotated open to increase posterior vertical alveolar and crown height. The reconstruction of a functional occlusal plane was achieved by uprighting the posterior teeth to correct asymmetric posterior vertical alveolar and crown height, using a full multibracket system incorporating four third molars and closing the space from the missing first molars and extraction of the questionable first molars. RESULTS: A normal overbite and overjet and adequate posterior support and anterior guidance were established, achieving a better intercuspation of the posterior teeth. A favorable perioral environment was created, with widened tongue space to produce an adequate airway. A well-balanced lip profile and almost symmetric face were achieved using the four wisdom teeth without extraction of the four premolars. Subsequent mandibular growth, with development of posterior vertical alveolar height and temporomandibular joint adaptation, has resulted in an almost symmetric posterior vertical height and joint structure between right and left sides. These factors have contributed to the occlusal stability maintained for more than 5 years. CONCLUSION: In the growing patient, with missing and/or early advanced caries of the first molars, it may be more beneficial to plan occlusal improvement through extraction of the questionable first molar rather than premolar extraction. This method of treatment can equalize posterior vertical dimension and does not restrict tongue space. In addition, this treatment method addresses the clinician's concern about postorthopedic relapse due to tongue habits and eruption of the third molars.- - - - - - - - - - ranking = 3keywords = mandible (Clic here for more details about this article) |
8/12. Mandibular osteomyelitis and tooth exfoliation following zoster-CMV co-infection.herpes zoster is a common viral infection, the oral soft tissue manifestations of which are widely known and recognized. Reports of spontaneous tooth exfoliation and jaw osteonecrosis following herpes zoster infection in the distribution of the trigeminal nerve are extremely infrequent and sporadic, with only 39 cases being reported in the literature. We report an additional case of mandibular osteomyelitis and spontaneous tooth exfoliation following herpes zoster infection, which occurred in the left mandible of a 70-year-old diabetic man; however, our case also showed CMV co-infection. The role of CMV in the pathogenesis of the osteonecrosis remains uncertain. awareness of the possibility of CMV co-infection in various oral diseases including oral ulcers, Kaposi's sarcoma, and herpes zoster infections especially in immunocompromised patients is important, since spread of the CMV can easily occur to other sites with potentially fatal consequences. early diagnosis can lead to effective treatment and prevention of complications.- - - - - - - - - - ranking = 1.0388419525377keywords = mandible, jaw (Clic here for more details about this article) |
9/12. herpes zoster in hiv infection with osteonecrosis of the jaw and tooth exfoliation.BACKGROUND: herpes zoster (HZ) infection of the trigeminal nerve is associated with complications such as postherpetic neuralgia, facial scarring, loss of hearing ability and conjunctivitis. Until 2005, postherpetic alveolar necrosis and spontaneous tooth exfoliation have been described in 20 cases unrelated to hiv infection. OBJECTIVE: The aim of this study was to describe hiv infection in patients (two women, two men, average age 30 years) who suffered from HZ attacks to their trigeminal nerves. MAIN OUTCOME MEASURES: None of the patients had received antiherpetic medications or antiretroviral therapy. hiv infection was only diagnosed after the development of HZ. Facial scarring with depigmentation and hyperesthesia (postherpetic neuralgia) was diagnosed in all four patients. Oral findings consisted of spontaneous loss of both maxillary or mandibular teeth. osteonecrosis of varying extent was also found. Treatment consisted of extractions of teeth and administration of antibiotics and analgesics. Healing of alveolar wounds was unremarkable. CONCLUSION: Complications affecting the alveolar bone and teeth seem to be rare in hiv-infected patients.- - - - - - - - - - ranking = 0.1553678101507keywords = jaw (Clic here for more details about this article) |
10/12. Tooth avulsions resulting from basketball net entanglement.The authors conducted a survey of dentists reporting tooth avulsions from basketball net accidents. Although the number of people injured was small, the dental injuries were serious. In many cases, multiple teeth were avulsed as a result of the maxillary anterior teeth becoming entangled in the basketball net while the patients were attempting to slamdunk a basketball either on a lowered backboard or from a raised take-off area. The authors present recommendations for preventing tooth avulsions resulting from basketball net entanglement.- - - - - - - - - - ranking = 0.0022820629480821keywords = lower (Clic here for more details about this article) |
