Diagnosis and management of occlusal wear: a case report.

The rationale for doing full mouth rehabilitation are, when occlusal forces become traumatic hampering the health of periodontal tissues, extensive occlusal diseases, trauma, temporomandibular joint disease and congenital disorders with malformed dentition. Literature exposes that full mouth fixed rehabilitation is one of the taxing procedures in the field of Prosthodontics. A critical aspect for successful occlusal rehabilitation is to determine the aetiology, correct sequence of treatment and most importantly the occlusal vertical dimension and centric relation in which to plan the treatment. A systematic approach in managing these patients can lead to a predictable and favourable prognosis. This article presents the stages of prosthodontic rehabilitation, from diagnosis to final treatment and follow-up, of a bruxer patient with severely worn dentition.

Prosthetic rehabilitation of postsurgical nasomaxillary hypoplasia for a patient following reconstructive surgery: a clinical report.

Repairs of the cleft nose, lip, and palatal deformity remain challenging endeavors for reconstructive surgeons. Postsurgical nasomaxillary hypoplasia is a common finding in patients with extensive clefts. This complex deformity has a pronounced impact on the social behavior and self image of the subject. Esthetic and functional rehabilitation of this postsurgical defect is scarcely reported in the literature. Support in the form of prostheses or stents to prevent tissue collapse is usually required in these patients following surgery. This clinical case presentation discusses the fabrication of an internal nasal stent for a cleft nose, lip, and palate patient following surgical reconstruction. Two prostheses using two prosthetic materials (Polymethyl methacrylate, flexible resin) were prepared to compare their efficacy. The final prostheses improved the patient's appearance, making the postsurgical defect less conspicuous.

Analysis of rugae in burn victims and cadavers to simulate rugae identification in cases of incineration and decomposition.

The most challenging situations in Forensic Odonto-Stomatology are mass disasters, where the forensic dentist is usually confronted with charred human remains or heavily decomposed or fragmented bodies. This article determines the extent of preservation of palatal rugae for use as an alternative identification tool in such situations, using a study group comprising burn victims and cadavers simulating forensic cases of incineration and decomposition. The thermal effects and the decomposition changes on the palatal rugae of burn victims with panfacial third degree burns and human cadavers in storage were respectively assessed and graded on a new scale. Ninety three percent of burn victims and 77% of human cadavers had Grade 0 changes (normal). When changes were noted, they were less pronounced than the generalized body involvement of burns in burn victims and the generalized body decomposition of human cadavers.

Computerized recording of the palatal rugae pattern and an evaluation of its application in forensic identification.

In circumstances where identification of an individual by fingerprint or dental record comparison is difficult, palatal rugae may be considered as an alternative source of comparative material. This article evaluates the use of palatal rugae patterns for forensic identification with an indigenously developed computer software program. Comprehensive computerized antemortem records were constructed for 250 subjects and a comparison matching process performed using both recorded and unrecorded samples. The efficiency of this computer-based identification method was then assessed. The program proved to have an average sensitivity of 0.93 and specificity of 1 and had a success rate of 92-97% in matches with digitized rugae pattern samples.
