1/57. A previously unreported surgical technique utilizing five different grafting materials to successfully achieve simultaneous alveolar regeneration and closure of a large oronasal defect.This case report describes the successful surgical and restorative management of an unusual cyst-granuloma combination that had expanded to perforate the labial and nasal parts of the maxillary bone. Enucleation and curettage of the lesions resulted in a large oronasal communication that presented a reconstructive challenge. Five different graft and/or barrier materials were used to close the oral and nasal openings and to regenerate the alveolus for implant placement and for aesthetic prosthetic restoration.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/57. Focal cemento-osseous dysplasia in the maxilla mimicking periapical granuloma.A case of focal cemento-osseous dysplasia of the maxilla in a 19-year-old man is reported. Clinically, the lesion resembled periapical pathosis of odontogenic origin. The clinical and histopathologic features of cemento-osseous dysplasia are reviewed.- - - - - - - - - - ranking = 769.98432321522keywords = periapical (Clic here for more details about this article) |
3/57. Maxillofacial osteonecrosis in a patient with multiple "idiopathic" facial pains.Previous investigations have identified focal areas of alveolar bone tenderness, increased mucosal temperature, abnormal anesthetic response, radiographic abnormality, increased radioisotope uptake on bone scans, and abnormal marrow within the quadrant of pain in patients with chronic, idiopathic facial pain. The present case reports a 53-year-old man with multiple debilitating, "idiopathic" chronic facial pains, including trigeminal neuralgia and atypical facial neuralgia. At necropsy he was found to have numerous separate and distinct areas of ischemic osteonecrosis on the side affected by the pains, one immediately beneath the major trigger point for the lancinating pain of the trigeminal neuralgia. This disease, called NICO (neuralgia-inducing cavitational osteonecrosis) when the jaws are involved, is a variation of the osteonecrosis that occurs in other bones, especially the femur. The underlying problem is vascular insufficiency, with intramedullary hypertension and multiple intraosseous infarctions occurring over time. The present case report illustrates the extreme difficulties involved in the diagnosis and treatment of this disease.- - - - - - - - - - ranking = 0.25keywords = alveolar (Clic here for more details about this article) |
4/57. 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 = 923.98118785826keywords = periapical (Clic here for more details about this article) |
5/57. Follicular or dentigerous (tooth-containing) cyst in the premaxilla of an otherwise edentulous 65-year-old man.A unilocular follicular or dentigerous cyst (FDC) with a diameter of 12 mm was observed incidentally in the premaxilla of a midsagittal section of the head of a 65-year-old cadaver. The mucosal lining of the cyst was grey in color and granular in texture: the osseous walls had a thickness of less than 1 mm. In the floor of the cyst, a slender, fully developed incisor tooth was fixed in a horizontal position. The alveolar processes of the maxilla and mandible were completely edentulous. Postmortem computer tomography showed the cyst in an osteolytic lesion of the premaxilla, and histology revealed a lining of non-keratinized stratified squamous epithelium supported by a lamina propria of dense connective tissue. copyright Wiley-Liss, Inc.- - - - - - - - - - ranking = 0.25keywords = alveolar (Clic here for more details about this article) |
6/57. eosinophilic granuloma as a form of inflammatory reaction. A case report.eosinophilic granuloma consists of the proliferation and/or accumulation of langerhans cells in the bones, generally of the cranium and face, as a uni- or multifocal cystic lesion. It is considered to be a localized chronic form of Langerhans cell disease. The most frequent oral location is the posterior part of the mandible, where the bone lesion often gives rise to lesions of the overlying soft tissues. We report a case showing bilateral involvement of the upper jaw and unilateral involvement of the mandible. The eosinophilic granulomas arose in association with odontogenic periapical infectious processes, suggesting that this disorder may be a form of inflammatory response.- - - - - - - - - - ranking = 153.99686464304keywords = periapical (Clic here for more details about this article) |
7/57. Odontogenic keratocyst of the maxilla presenting as periodontal abscess.This is a case report of an odontogenic keratocyst of the maxilla initially diagnosed and treated as a periodontal abscess. The occurrence of odontogenic keratocyst in the maxilla with involvement of the antrum is relatively rare. The radiological appearance of this lesion on both conventional and panoramic radiography can be misinterpreted and emphasizes the usefulness of the computed tomography in this region.- - - - - - - - - - ranking = 0.29695687179011keywords = abscess (Clic here for more details about this article) |
8/57. Maintaining and attenuating periodontal tissues for aesthetic implant placement.Alveolar ridge resorption and soft tissue recession after tooth extraction inevitably disrupted the harmonious pre-existing periodontal complex, compromising clinicians' ability to recreate successful aesthetic restorations. Although numerous surgical procedures had been advocated for the augmentation of both the alveolar ridge and its soft tissue to ideal contours, questions remain regarding viability and predictability of these procedures. This is especially critical in the maxillary anterior region, where a the condition of the soft tissue complex and its relationship to the implant restoration and its adjacent dentition often determines the implant's success. The described technique of retaining the root remnant and inducing the proliferation of the surrounding tissue in conjunction with immediate implant placement results in the preservation of existing soft and hard tissue, thus minimizing the necessity of grafting procedures and facilitating primary flap closure during implant placement.- - - - - - - - - - ranking = 0.25keywords = alveolar (Clic here for more details about this article) |
9/57. Segmental odontomaxillary dysplasia: clinical, radiological and histological aspects of four cases.Segmental odontomaxillary dysplasia (SOD) is a rare developmental disorder of the maxilla, primarily involving the posterior part of the maxilla. Clinically, the disorder is often diagnosed in early childhood due to a unilateral buccolingual expansion of the posterior alveolar process, gingival enlargement, absence of one or both premolars in the affected region, delayed eruption of the adjacent teeth and malformations of the primary molars. In this report, four patients with SOD are described. The findings were similar to earlier reports, but for the first time an ipsilateral rough erythema on the skin in two of the subjects is reported.- - - - - - - - - - ranking = 0.25keywords = alveolar (Clic here for more details about this article) |
10/57. Simultaneous cortex bone plate graft with particulate marrow and cancellous bone for reliable closure of palatal fistulae associated with cleft deformities.OBJECTIVE: The purpose of this study was to evaluate the effectiveness of simultaneous cortex bone plate (CBP) graft with particulate marrow and cancellous bone (PMCB) graft for reliable closure of palatal fistulae associated with alveolar clefts. DESIGN: Following standard secondary bone graft preparation of the cleft site, CBP harvested from the medial iliac crest was inserted into the palatal deficiency. This was followed by suturing the palatal mucosa. PMCB was then packed between the cortical bone and the reconstructed nasal floor. SETTING: Ten consecutive patients with palatal fistula were operated on at tokyo Medical and Dental University Hospital from 1998 to 2000. Primary palatal repair was performed in 7 out of 10 patients at our center and in 3 out of 10 patients at other hospitals. patients: Ten patients (6 boys and men, 4 girls and women) with a palatal fistula associated with an alveolar cleft were studied. Ages ranged from 12 to 26 years. INTERVENTIONS: All patients underwent simultaneous CBP graft with PMCB graft for closure of palatal fistula under general anesthesia. RESULTS: Complete closure of palatal fistulae were obtained in 8 out of 10 cases. A very small asymptomatic fistula remained in one patient. Total necrosis of the labial flap with a residual palatal fistula occurred in one patient. CONCLUSIONS: Simultaneous CBP graft with PMCB graft could be more reliable than PMCB alone for closure of a cleft associated palatal fistula.- - - - - - - - - - ranking = 0.5keywords = alveolar (Clic here for more details about this article) |
