Survival of tooth-implant connections: A systematic review and meta-analysis.

Implant-supported prostheses have considerable biomechanical advantages in partially edentulous patients when compared to other prosthetic options. Given the steady drop in the frequency of patients reporting with complete edentulism, it is not unusual to see situations where teeth and implants can be splinted to provide support for fixed prostheses. A tooth implant prosthesis differs majorly from an implant-supported prosthesis in terms of force dissipation and design.

Comparing the functional efficiency of tooth-supported overdentures and implant-supported overdentures in patients requiring oral rehabilitation: A systematic review.

The aim of this article is to compare the functional efficiency of tooth-supported overdentures and implant-supported overdentures in patients requiring oral rehabilitation. The comparative quantification of the improvement in functional efficiency is very difficult to assess because of the variations in the study designs like the age of the population studied, the male-to-female ratio, the outcome measures used, the clinical setting in which the implant therapy was provided, oral status of the subjects included and the type of implant therapy provided. In this systematic review, the articles included compared the functional efficiency by assessing the bite force, chewing efficiency, electromyographic (EMG) changes measured by EMG analysis, and patient satisfaction for subjects who have been rehabilitated with either a tooth-supported overdenture or an implant-supported overdenture.

Accuracy of an intraoral digital impression: A review.

Intraoral scanners (IOSs) are used for capturing the direct optical impressions in dentistry. The development of three-dimensional technology and the trend of increasing the use of IOSs in dental office routine lead to the need to assess the accuracy of intraoral digital impressions. The aim of this review was to assess the accuracy of the different IOS and the effect of different variables on the accuracy outcome.

A Simple Technique to Fabricate Custom Made Occlusal Plane Template.

The plane of occlusion represents the average curvature of the occlusal surfaces of anterior and posterior teeth rather than a flat surface. An anteroposterior curve, the curve of Spee and the mediolateral curve, the curve of Wilson determine the position of posterior teeth. Management of patients with uneven occlusal plane is an essential step for the long term success of the treatment.

Effect of Dietary Simulating Solvents on the Mechanical Properties of Provisional Restorative Materials-An In Vitro Study.

The purpose of this investigation was to evaluate the mechanical properties of provisional restorative materials after storage in dietary simulating solvents. A total of 120 specimens, 40 specimens each of Luxatemp Star, Revotek LC and DPI Self Cure were prepared. The specimens were divided into four groups with 10 specimens each and stored in dietary simulating solvents for 7 days at 37 °C as follows: Group I-Control, Group II-Artificial saliva, Group III-0.

Effect of Varying Layers of Two Die Spacers on Precementation Space of Full Coverage Restorations.

The purpose of this study was to evaluate and compare the effect of varying layers of two commercially available die spacers on pre-cementation space of full coverage restorations in vitro and in vivo. Seven dies were prepared for each of 15 subjects. On three dies 1, 2, 3 layers of Pico-fit and on other three dies 1, 2, 3 layers of Yeti die spacers applied, wax pattern fabricated, invested and cast.

Functional and esthetic rehabilitation of mutilated dentition associated with amelogenesis imperfecta.

This clinical case report describes the oral rehabilitation of an adult female patient diagnosed with hypoplastic amelogenesis imperfecta with inadequate, deteriorated restorations of anterior teeth, inadequate clinical crown heights of posterior teeth due to severe attrition of hypoplastic enamel. Treatment included extraction of teeth with poor prognosis, root canal treatment and crown lengthening of severely worn out teeth & full coverage porcelain-fused-to metal fixed restoration of entire dentition. The main objectives of the selected treatment were to enhance the esthetics, restore masticatory function and eliminate the teeth sensitivity.

Comparative study of shade matching performance of dental students under natural daylight and daylight lamp conditions.

Background: As visual shade matching is subject to light source variables, this study was conducted to compare shade matching performance of dental students under two lighting conditions, ie, natural daylight and a commercially available daylight lamp.

Materials And Methods: Two sets of porcelain discs were prepared. The first set consisted of eight porcelain discs of shades A2, A3, A3.

A simplified chair-side remount technique using customized mounting platforms.

Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. Fabrication of complete dentures comprises of clinical and laboratory procedures that should be executed accurately for achieving success with fabricated dentures. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the final prosthesis.

Comparison of effect of desensitizing agents on the retention of crowns cemented with luting agents: an in vitro study.

Purpose: Many dentists use desensitizing agents to prevent hypersensitivity. This study compared and evaluated the effect of two desensitizing agents on the retention of cast crowns when cemented with various luting agents.

Materials And Methods: Ninety freshly extracted human molars were prepared with flat occlusal surface, 6 degree taper and approximately 4 mm axial length.

Determination of the occlusal plane using a custom-made occlusal plane analyzer: a clinical report.

In fixed prosthodontic procedures, when it has been determined that restoration of all or most of the posterior teeth is necessary, the use of the Broderick occlusal plane analyzer provides an easy and practical method to determine an occlusal plane that will fulfill esthetic and functional occlusion requirements. However, several manufacturers of semiadjustable articulators offer no such occlusal plane analyzers for use with these instruments. This article demonstrates the use of a custom-made Broderick occlusal plane analyzer with a semiadjustable articulator to determine the correct curve of Spee for the occlusal plane.
