1/48. Spacemaking metal structures for nonresorbable membranes in guided bone regeneration around implants. Two case reports.This article presents a surgical technique to promote bone regeneration and enlargement of localized alveolar ridge defects in the mandible. The purpose of this study was to investigate the use of spacemaking gold frames used in combination with expanded polytetrafluoroethylene Gore-Tex augmentation membranes (WL Gore) on two patients to create and maintain adequate space for the regeneration of bone. The membrane was sutured under the frame and the assembly was bent and adapted over the residual bony defect to create a dome and prevent the expanded polytetrafluoroethylene barrier membranes from collapsing into the defects. The framed membranes have also been positioned over dehisced implants. After a healing period of 12 months, a second-stage surgery procedure was performed to remove the gold frames and expanded polytetrafluoroethylene membranes and to connect the healing abutments. The gain of bone dimension was assessed by standardized measurements. On both patients the spaces created by the framed membranes were completely filled with newly regenerated bone. Biopsies from the treated sites revealed new bone formation.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/48. Use of crestal bone for augmentation of extremely knife-edged alveolar ridges prior to implant placement: report of 3 cases.A technique is presented for interforaminal lateral augmentation of mandibles with adequate bone height, but extremely knife-edged mandibular alveolar ridges (Class IV of Cawood and Howell's classification of residual ridges), in which the crestal portion of the knife-edged ridge is used as grafting material. Following an osteotomy and rotation of the grafts by 180 degrees, the grafts were fixed to the residual ridge below the osteotomy line by means of miniscrews. All grafts showed only mild resorption after a healing period of 3 months, and it was possible to place 4 implants in the now sufficiently wide host region.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
3/48. The less than 7-mm edentulous mandible: the implant/overdenture reconstructive option.The edentulous patient with a severely atrophic mandible (less than 7 mm in height) can be successfully restored with two endosseous implants and a clip-bar overdenture, with minimal morbidity. Two of the three cases reported illustrate the long-term potential of this treatment modality.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
4/48. Etiology and management of mandibular fractures associated with endosteal implants in the atrophic mandible.mandibular fractures can occur with the insertion of endosseous implants. Four patients whose mandibles were fractured with the removal or insertion of mandibular endosseous implants are described. Three of the patients required an autogenous bone graft to repair the fracture, and 1 patient was managed with a reconstruction plate. Strategies for prevention and treatment of this uncommon complication are discussed.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
5/48. Computerized tomography in the management and follow-up of extensive periapical lesion.Radiographs are good diagnostic aids in endodontics, although they have limitations. The purpose of this article is to discuss the use of computerized tomography in differential diagnosis, treatment planning, follow-up and overall clinical management of complex periapical lesions. A clinical case of an extensive symptomatic periapical lesion of the upper jaw is presented, in which the use of computerized tomography allowed evaluation of the true extent of the lesion and its spatial relationship to important anatomical landmarks. Computerized tomography also provided specific information about the type of lesion and the degree of bone repair which had taken place 18 months after non-surgical treatment had been completed.- - - - - - - - - - ranking = 0.019649052523034keywords = jaw (Clic here for more details about this article) |
6/48. Advanced alveolar crest atrophy: an alternative treatment technique for maxilla and mandible.A concept of oral implantology for the treatment of advanced crest atrophy is presented: The lateral insertion technique with disk-design implants is less invasive than bone grafting. An implant case demonstrates the simultaneous surgery of an edentulous maxilla and a mandible. Implant loading zones in the anterior and posterior areas of the arch are created with disk-design implants. Their support is tricortical or multicortical. Seven to eight days after surgery, the implants are immediately loaded with fixed esthetic temporaries. After another 40 days, the definitive restorations on the implants can be fabricated. The procedure is safe and shortens chairtime.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
7/48. Myospherulosis complicating cortical block grafting: a case report.BACKGROUND: Myospherulosis of the oral cavity is an inflammatory, granulomatous lesion historically associated with the use of petrolatum-based antibiotic ointment placed in third molar extraction sites to prevent postoperative infection. methods: A case of bilateral myospherulosis is presented, in which large lesions complicated the procurement of a cortical block graft used to prepare a mandibular molar edentulous space for implant placement. By obtaining the block graft from a more lateral location on the mandible, an adequate graft was procured and was successfully grafted into an atrophic edentulous ridge. RESULTS: The cortical block graft was successfully incorporated by the recipient site, which received a wide-body, threaded dental implant 6 months later. Healing was uncomplicated, and a functional implant-supported restoration was successfully achieved. CONCLUSIONS: Myospherulosis, though rare today, may present a significant obstacle to the procurement of cortical block grafts. In this case, thorough debridement of the material resulted in subsequent healing of the myospherulosis defect, but prevented procurement of the cortical graft from the planned site. The dimension and volume of the neighboring cortical bone were adequate, and the augmented edentulous space was subsequently restored with a functional endosseous implant. The success seen in these 2 sites would seem to confirm the assumption that size and location of myospherulosis defects are critical factors in obtaining a successful clinical result in implant patients.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
8/48. Placement of implants into ridges grafted with bioplant HTR synthetic bone: histological long-term case history reports.Following alveolar ridge grafting procedures for ridge preservation, for example, the immediate filling of extraction sockets, and ridge augmentation, for example, the building up of the atrophic jawbone, punch biopsies were obtained at various times postextraction prior to the placement of endosseous root-form implants. These histological sections provided an opportunity to study the bony regenerative response to an osteoconductive synthetic graft material and longer term interactions over a period from 8 months to 12 years. The formation and remodeling of healthy dense lamina of bone in areas where bone voids previously existed either from healed or immediate extraction sockets or where there was jawbone atrophy resulting from multiple tooth loss was observed. The grafting procedures enabled dentists to place implants into sites that would have been impossible if not for these preimplant grafting procedures. The jawbone areas studied involved grafted single sites and quadrants as well as full arch augmentation with a calcified microporous copolymer (Bioplant HTR Synthetic Bone, Bioplant Inc, South Norwalk, Conn) graft material. Retrospective case reports of 24 patients were followed radiographically and clinically to 12 years post-alveolar-ridge grafting and subsequently to 5 years after implants were placed into these augmented ridges. Implant and grafting histories from 4.7 months to 17 years are reported for three of these patients. General applications of synthetic bone grafting before implant placement are recommended.- - - - - - - - - - ranking = 0.058947157569103keywords = jaw (Clic here for more details about this article) |
9/48. Langerhans cell histiocytosis: recurrent lesions affecting mandible in a 10-year-old patient.hand-Schuller-Christian disease is a multifocal variant of eosinophilic granuloma, characterised by the classical triad of bony lesions, exophthalmos and diabetes insipidus. This case relates recurrent Langerhans' cell histiocytosis lesions presented as destruction of periodontal support associated with diabetes in a 10-year-old patient. Medical history suggests that the case represents a case of hand-Schuller Christian disease.- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
10/48. Simultaneous bimaxillary alveolar ridge augmentation by a single free fibular transfer: a case report.Class VI atrophy according to Cawood still represents a major challenge in pre-prosthetic surgery. Reconstruction of mandibular and maxillary bony defects using microvascular techniques is safe and reliable. The fibula, due to its morphological properties, is ideal for alveolar ridge augmentation and its donor site morbidity is the lowest among vascularized bone flaps. In this paper, we report the first case, to our knowledge, of extreme atrophy of both jaws, successfully treated by simultaneous bony augmentation of the maxillary and mandibular alveolar ridges with just one free fibula flap. Pre-operative planning, surgical technique and prosthetic restoration are discussed in detail.- - - - - - - - - - ranking = 0.019649052523034keywords = jaw (Clic here for more details about this article) |
