RESUMO
Surgical resection of mandible causes deviation of mandible toward affected side, resulting in loss of occlusal contact. This article presents twin rows of nonanatomic teeth on the untreated side of maxillary complete denture. The palatal row helps in mastication, whereas the buccal row supports the cheeks and improves the aesthetics.
RESUMO
AIM: The aim of this study was to compare effect of different metal coping designs on fracture resistance of porcelain in metal ceramic restorations. MATERIALS AND METHODS: Fracture resistance of porcelain was assessed in porcelain fused to metal crowns with three different coping designs i.e. metal coping extension on labial surface upto gingivoaxial line angle, metal coping extension 1mm short of the gingivoaxial line angle and metal coping with 0.4mm wide labial metal collar. For crowns without labial metal collar margin; shoulder porcelain was used to build the labial cervical margin of the crowns. RESULTS: RESULTS were assessed with statistical analysis using the student unpaired't' test. Visual examination of the fractured specimens of group A, B and C showed remarkably similar failure modes with nearly all specimens failing through a shear fracture of porcelain from load point to facial margin of the crown. CONCLUSION: Within the scope of this study, it was observed that the mean facture strength of the samples with shoulder porcelain labial margins having metal coping design extending upto gingivoaxial line angle of the finish line was highest as compared to samples with shoulder porcelain labial margins having metal coping design 1mm short of gingivoaxial line angle & samples having porcelain fused to metal coping design with 0.4mm wide metal collar.

A study of the masticatory performance of 30 patients with balancing contacts in centric relation was compared with an equal number of patients with balancing contacts in both centric and eccentric relations. The study failed to show any significant difference between masticatory performance of the two groups.

Leuprolide acetate, a gonadotropin-releasing hormone analogue, produced a variety of beneficial therapeutic responses in five patients with ovarian carcinoma. Four patients had failed intensive chemotherapy with alkylating agents, cisplatin, and Adriamycin. All had one or more clinical conditions that precluded treatment with cytotoxic agents and characteristics associated with resistance to hormone therapy. Our findings support evaluation of expanded eligibility criteria for new hormonal therapy in cases of refractory ovarian carcinoma.
