Influence of disclusion time reduction on changes in posterior implant prosthesis occlusion and its association with crestal bone loss: A clinical study.

Statement Of Problem: A prolonged period of high magnitude occlusal contact can be associated with rapid changes of the occlusal surfaces and, in turn, may lead to overloading of an implant-supported prosthesis. Crestal bone loss may be one of the repercussions of overloading, but the influence of disclusion time (DT) reduction (DTR) is unclear.

Purpose: The purpose of this clinical study was to evaluate the role of DTR in preventing the occlusal changes and crestal bone loss at progressive time intervals of 1 week, 3 months, and 6 months in posterior implant-supported prostheses.

Comparison of quality of bone and insertion torque values of early implants placed at 6 and 8 weeks in sockets preserved with advanced platelet-rich fibrin: A randomized controlled trial.

Aim: Successful functional and esthetic rehabilitation of edentulous jaws with implants depends on the optimal timing of placement, surgical protocol, materials used, cost-effectiveness, and satisfying patient needs. Increasing demand for shorter treatment times necessitates the immediate placement protocol. However, researchers have demonstrateda higher failure rate.

An evaluation of antimicrobial potential of irreversible hydrocolloid impression material incorporated with chitosan.

Aim: To evaluate the antimicrobial potential of irreversible hydrocolloid impression material manipulated using chitosan impregnated solution at various time intervals.

Setting And Design: Evaluative invivo study design.

Materials And Methods: Maxillary impressions made for 20 dentulous volunteers using irreversible hydrocolloid impression material manipulated using distilled water as control and using 1% chitosan impregnated solution as test group using stock metal trays with one-week interval.

An in-vitro study to compare the temperature rise in the pulp chamber by direct method using three different provisional restorative materials.

Statement Of Problem: The provisional restorative materials in fixed prosthodontics are basically bis-GMA resins which releases exothermic temperature while polymerization which can damage the pulp. Intrapulpal temperature exceeding 42.5°C found to result in irreversible damage to the pulp.

The effect of temperature on compressive and tensile strengths of commonly used luting cements: an in vitro study.

Background: The luting cements must withstand masticatory and parafunctional stresses in the warm and wet oral environment. Mouth temperature and the temperature of the ingested foods may induce thermal variation and plastic deformation within the cements and might affect the strength properties. The objectives of this study were to evaluate the effect of temperature on the compressive and diametral tensile strengths of two polycarboxylate, a conventional glass ionomer and a resin modified glass ionomer luting cements and, to compare the compressive strength and the diametral tensile strength of the selected luting cements at varying temperatures.

Single step approach to make diagnostic impressions of both the arches and face bow transfer: a novel technique.

Context: Mounting the maxillary and mandibular dentulous casts for Diagnostic purpose requires many steps (including making maxillary and mandibular impressions, face-bow transfer, and bite registration) or many appointments. A simple new technique of doing all of this together without compromising on the accuracy can save time over the conventional mounting procedure.

Aim: To compare the accuracy of a new technique of a single-step diagnostic mounting procedure with that of the conventional diagnostic mounting procedure.

A comparative study of inter-abutment distance of dies made from full arch dual-arch impression trays with those made from full arch stock trays: an in vitro study.

Objectives: The dual-arch impression technique is convenient in that it makes the required maxillary and mandibular impressions, as well as the inter-occlusal record in one procedure. The accuracy of inter-abutment distance in dies fabricated from dual-arch impression technique remains in question because there is little information available in the literature.

Materials And Methods: This study was conducted to evaluate the accuracy of inter-abutment distance in dies obtained from full arch dual-arch trays with those obtained from full arch stock metal trays.
