A cephalometric study to establish the relationship of the occlusal plane to the three different ala-tragal lines and the Frankfort horizontal plane in different head forms.

BACKGROUND: The aim of the study is to compare the relationship of the occlusal plane to 3 different ala-tragal lines, namely the superior, middle and inferior lines, in individuals having different head forms and its relation to the Frankfort horizontal plane. METHODOLOGY: A total of 75 lateral cephalometric radiographs of subjects with natural dentition, having full complement of teeth, between the age group of 18-25 were screened and selected. Lateral cephalogram were made for each subjects in an open mouth position. Prior to making the lateral cephalogram, radiopaque markers were placed on the superior, middle and inferior tragus points and on the inferior border of the ala of the nose. Cephalometric tracing was done over each cephalogram. RESULTS: In mesiocephalic head form the middle ala-tragal line was most parallel to the occlusal plane having a mean angle of (1.96°). In dolichocephalic headform, the superior ala-tragal line was most parallel to the occlusal plane having a mean angle of (0.48°). In brachycephalic head form, the middle ala-tragal line was most parallel to the occlusal plane having a mean angle of (2.08°). The mean angulations of occlusal plane to FH plane is 11.04°, 10.16° and 10.60° in mesiocephalic, dolichocephalic and brachycephalic head forms, respectively. RESULTS AND CONCLUSION: The study concludes that the middle ala-tragal line can be used as a reference for the mesiocephalic head form and the superior ala-tragal line for the dolichocephalic and brachycephalic head form as a reference to establish the occlusal plane.

Prosthetic rehabilitation of a marginally resected mandibular arch with a metal reinforced telescopic overdenture.

Success of the prosthesis after mandibular resection is related directly to the amount of the remaining bone and soft tissue present. The prognosis for mandibulectomy patients becomes less favorable as the size of the resection increases. Prosthetic rehabilitation for such patients is a challenge for clinicians. Without preprosthetic reconstructive surgery, denture fabrication for mandibulectomy patients becomes extremely difficult. Telescopic dentures is a modality of treatment consisting of an inner or primary telescopic coping which is permanently cemented to an abutment and an outer or secondary telescopic coping which is attached to the prosthesis. These copings protect the abutment from dental caries and thermal irritations and also provide retention and stabilization of the secondary coping. The secondary coping engages the primary copings to form a telescopic unit and it provides retention and stability to the prosthesis. This clinical report aims at utilizing the remaining natural teeth for a mandibular overdenture with telescopic coping.

Personal identification using QR Code incorporated in dentures / Identificação pessoal usando código QR incorporado em próteses totais

Forensic dentistry is finding increased application in identifying deceased individuals. Incorporating patient identification system in dentures is one of the measures taken in this regard. There are several denture identification measures, each having their own merits and demerits. This article describes a new denture identification system using Quick Response Code incorporated in dentures. This identification system can be very cost-effective, store lot of patient-related information and be easily accessible to the dentist...

A identificação de indivíduos falecidos é uma demanda crescente em Odontologia. A incorporação de sistemas de identificação na prótese total de pacientes é um procedimento de possível. Existem vários sistemas de identificação em próteses totais, cada um com seus próprios méritos e deméritos. Este artigo descreve um novo sistema de identificação de dentadura utilizando o código QR incorporado em próteses totais. Este sistema de identificação é de baixo custo, armazena grande quantidade de informações relacionadas ao paciente e é de fácil acesso ao dentista...
