Mandibular deviation is multifactorial defect and its severity is based on the extent of osseous and soft tissue involvement, degree of tongue impaired, the loss of sensory and motor innervations, the type of wound closure, the presence of remaining natural teeth and finally the first initiation of prosthetic treatment. We describe a case of prosthetic management of a maxillary partially edentulous patient with hemimandibulectomy who reported after 4 years of postsurgical cancer therapy. A simple maxillary guided hollow inclined plane with twin occlusion acrylic prosthesis was fabricated as a functional training device to correct mandibular deviation, restore maxillomandibular relation and occlusal approximation. The patient was able to functionally achieve good maxillomandibular occlusal approximation with guidance therapy combined with physiotherapy in 2 weeks. A 6 months follow-up revealed patient satisfactory appreciation by understanding the limitations of overall prosthetic rehabilitation.

Introduction: Our aim was to determine if students who perform well on an initial preclinical examination are more accurate on self-assessments with successive examination. Materials and Methods: This was an observational, descriptive, cross-sectional survey. Ninety-one 2nd year dental students completed two consecutive preclinical examinations on ideal teeth arrangement and two self-assessments. Self-assessment was done using a validated, structured, self-designed questionnaire named “prosthetic denture setup–self assessment questionnaire.” The examinations involved artificial teeth arrangement in Class I jaw relation on maxillary and mandibular ideal edentulous casts mounted on a mean value articulator simulating the clinical procedure of a complete denture patient. Students' and their instructor's assessments were evaluated separately, and statistical results were obtained using t-test and Pearson's product moment correlation coefficient test. Regression analysis was done to predict the student self-assessment and validated self-assessment scores on examination outcomes for both indexed and nonindexed values. Results: The results indicated a significant increase in the examination and student self-assessment mean scores. Regression analysis indicated changes in student self-assessment scores, explained 11.9% of the variation in examination scores. Conclusion: Improvement in student self-assessment also showed improvement in successive examination assessments among dental students completing a preclinical denture setup procedure. The following core competencies are addressed in this article: Medical knowledge, Practice-based learning and improvement, Systems-based practice.

Background The most common complaint following cementation is the occurrence of post cementation sensitivity. The sensitivity to cold stimulus after cementation can be indicative of a gap present below the crown or a marginal gap connecting to opened tubules which emerge into the pulp. A pulp fluid outflow occurs as a result of the contraction of dentinal fluid in this gap which causes postoperative sensitivity. Thus luting agents should form complete seal between fabricated restoration and prepared tooth.Objectives The current study was conducted to clinically evaluate post-cementation hypersensitivity of bioactive luting cement in a randomized clinical control trial using resin modified glass ionomer cement RMGIC as the control.Methods According to standard tooth preparation protocol the teeth were prepared to receive Porcelain fused to metal PFM bridges on both sides of the mouth. PFM final restorations were cemented using Bioactive and RMGIC luting cement. Sensitivity was tested by using compressed airbiting pressure tests and cold water and was evaluated by using Schiff scale with 0-3 scores before cementation soon after cementation one week and three months post cementation.Results Almost all the patients responded to hypersensitivity at pre-cementation and baseline with compressed airbiting pressure tests and cold water. The sensitivity scores reduced over time one week and three months for both the luting agents.Conclusion Based on the results it can be concluded that the bioactive luting cement exhibited lesser sensitivity scores when compared to resin modified GIC luting cement.

In the search for alternative and esthetic restorative materials, many all-ceramic systems have been introduced for the general practitioner. They are used as veneers, inlays/onlays, crowns, and as enamel/dentin bonded partial or total coverage without macroretention. This article describes a classification of the different commercial all-ceramic systems and gives a review of their clinical durability. The primary changes in the field were the proliferation of zirconia-based frameworks and computer-aided fabrication of prostheses, as well as, a trend toward more clinically relevant in vitro test methods. Newer reinforced ceramics showed better durability then the earlier fired ceramic reconstructions. This report includes an overview of ceramic fabrication methods, suggestions for critical assessment of material property data.
