1/23. Presenile mandibular atrophy: its aetiology, clinical evaluation and treatment by jaw augmentation.Presenile mandibular atrophy has been regarded as a bony condition in isolation. Direct vision of the mandible at the lower border and ascending rami at augmentation procedures in two cases clearly showed that the condition had affected the whole bone in all dimensions. A suggestion is made that mandibular atrophy arises as a result of many contributory factors, some local, but usually based on generalised undisclosed malabsorption states or osteoporosis.- - - - - - - - - - ranking = 1keywords = mandible, jaw (Clic here for more details about this article) |
2/23. Atrophoderma of moulin with preceding inflammation.A 16-year-old Vietnamese man presented to the dermatology Clinic with a 10-year history of bizarre brown patches, which initially started as red asymptomatic "bumps" on the trunk, upper and lower extremities, and face. His past medical history was significant for hypothyroidism and idiopathic urticaria. He was on Eltroxin for hypothyroidism. The family history was noncontributory. physical examination revealed two types of lesion: erythematous, well-circumscribed papules in a linear configuration along with linear hyperpigmented atrophic patches following Blaschko's lines were noted on the lower extremities (Fig. 1), right upper extremity, right flank (Fig. 2), and right jawline. Initial biopsies taken from the papular lesions on the right thigh and right elbow revealed the following changes. The first biopsy showed a slightly thinned epidermis with prominent dilated blood vessels in the superficial dermis. There also appeared to be a slight increase in the amount of collagen in the deep dermis. The findings were reported as in keeping with "epithelial atrophy." The second biopsy from the lesion on the right elbow revealed an acanthotic epidermis. The granular layer was absent in several areas and there was marked overlying parakeratosis. In the dermis, there was a heavy perivascular lymphocytic infiltrate. The appearances were consistent with a psoriasiform dermatitis (Fig. 3). A biopsy taken from the left thigh approximately 18 months later showed slight irregular acanthosis with dermal edema, dilated blood vessels, and a patchy lymphocytic infiltrate. The appearances were compatible with mild inflammation.- - - - - - - - - - ranking = 0.005276432994427keywords = jaw (Clic here for more details about this article) |
3/23. Surgical simulation of Class III edentulous patient using a 3D craniofacial model: report of a case.A case of edentulous prognathism in a 46-year-old Japanese male is presented. We described the outcome of the patient who underwent simultaneous sagittal splitting ramus osteotomy of the edentulous mandible, interpositional bone graft of severely atrophic edentulous jaws, and delayed placement of titanium implants for reconstruction. We highly recommend performing a surgical simulation using a craniofacial model of the patient's anatomy created using CT image data. The procedure provides almost ideal maxillary and mandibular contours.- - - - - - - - - - ranking = 0.98417070101672keywords = mandible, jaw (Clic here for more details about this article) |
4/23. dermabrasion: a curative treatment for melasma.Melasma is fairly common in Asian patients with a dark skin tone. It has long been known for its recalcitrance to any form of treatment. The objective of this article is to propose mechanical dermabrasion as a curative treatment for this entity. Five hundred and thirty-three patients with melasma were treated by mechanical dermabrasion using a rotatory diamond fraise. Four hundred and ten patients were available for long-term follow-up (mean follow-up time 5 years, range 1-9 years). Out of 410 patients, 398 (97%) achieved persistent clearance of melasma; in the remaining cases, there was partial recurrence after initial clearance. The common temporary sequelae were postoperative erythema or hyperpigmentation, pruritus, and milia formation. Two patients developed hypertrophic scars, one on the upper lip and one on the jawline, and one patient had permanent hypopigmentation on the forehead. In conclusion, mechanical dermabrasion is a relatively safe and highly effective means for curing melasma.- - - - - - - - - - ranking = 0.005276432994427keywords = jaw (Clic here for more details about this article) |
5/23. Fracture of the genial tubercles associated with a mandibular denture: a clinical report.Fracture of the genial tubercles without an associated mandibular fracture is uncommon. It occurs mainly in patients wearing a complete mandibular denture when the mandible is atrophied and the genial tubercles are hypertrophied. Only 7 reports have been found in the English-language literature. An additional situation of a 70-year-old woman is presented along with a review of the literature. A conservative approach to treatment is advised with this type of fracture. The use of dental implants should be considered in patients with hypertrophied tubercles to prevent such fracture.- - - - - - - - - - ranking = 0.97889426802229keywords = mandible (Clic here for more details about this article) |

7/23. Mandibular fracture caused by peri-implant bone loss: report of a case.BACKGROUND: A major complication related to excessive bone loss around implants is fracture of the mandible. This complication is most likely to occur in a very atrophic mandible. A 57-year-old woman presented with progressive pain and swelling that had been present for 5 days in the right frontal region of the mandible. An intraoral radiograph revealed a radiolucency around one of the implants in the interforaminal region. methods: Ten years earlier, 4 hollow-screw implants of 10 mm length had been inserted in the interforaminal region of the edentulous mandible. Throughout the 10-year postoperative period, no adverse clinical events were seen; however, during the last 7 years, no radiographic follow-up was performed. Mobility was tested after removal of the bar, on which one of the implants appeared to be mobile. The mobile implant was removed together with the fibrous tissue. RESULTS: At a recall visit 2 weeks later, a radiograph revealed a fracture of the mandible at the explantation site. Characteristic features of the hollow-screw implant are the hollow body and the transverse openings in the side walls of the implant. It has been reported that these characteristic features can enhance infection and rapid bone loss, but a case of mandibular fracture has never been described. CONCLUSION: Radiographs should be taken on a regular and perhaps more frequent basis to diagnose excessive bone loss, so that measures can be taken to prevent the risk of mandibular fracture.- - - - - - - - - - ranking = 4.8944713401115keywords = mandible (Clic here for more details about this article) |
8/23. fibula microvascular free tissue reconstruction of the severely comminuted atrophic mandible fracture--case report.Severely atrophic comminuted fractures of the mandible often have inadequate bone stock available to allow for adequate rigid fixation and subsequent progression to union. Grafting with rib, iliac crest or a variety of allograft materials is required in order to increase the success rate of the repair in this patient population. In this article, we report our favourable experience in using a fibula microvascular free tissue transfer for the treatment of a particularly challenging patient with a fractured atrophic mandible. Secondary implant rehabilitation completed the reconstruction. This method may represent an alternative in the treatment of fractures of the severely atrophic mandible in select individuals.- - - - - - - - - - ranking = 6.852259876156keywords = mandible (Clic here for more details about this article) |
9/23. Horizontal alveolar distraction of the narrow maxillary ridge for implant placement.PURPOSE: The purpose of this report was to describe a surgical technique for performing horizontal alveolar distraction of the knife-edge maxillary ridge. PATIENT AND methods: The patient was a 17-year-old woman with atrophy of the alveolar rim in the anterior upper jaw, which had inadequate width for implant placement. The transport segment was constructed by the osteotomy of the labial cortex of the alveolus. A transport plate of a distractor (lead system; Stryker Leibinger, Kalamazoo, MI) was placed on the transport segment. The distraction rod was inserted horizontally, and put in contact with the palatal cortex at the top. A base plate was not placed. RESULTS: The alveolar distraction was successfully performed to gain 6.0 mm in width and 0.5 mm in height, allowing placement of three 14-mm implants. All the implants were integrated so as to support the prosthesis. CONCLUSIONS: Alveolar distraction can be useful for augmenting the narrow ridge horizontally and placement of implants.- - - - - - - - - - ranking = 0.005276432994427keywords = jaw (Clic here for more details about this article) |
10/23. Implant-supported bar-latch overdenture for the severely atrophied, edentulous jaw: a case report.The removable implant-supported prosthesis is the treatment of choice in some clinical situations. Despite its technically demanding fabrication and the resultant high cost, the bar-latch overdenture provides stability and is easy for patients to manage. A case report illustrating the surgical and prosthetic procedures of this treatment option, including laboratory fabrication, is presented.- - - - - - - - - - ranking = 0.021105731977708keywords = jaw (Clic here for more details about this article) |
