Evaluation of bonding efficiency between facial silicone and acrylic resin using different bonding agents and surface alterations.

Purpose: The aim of the study was to evaluate the effect of 3 silicone primers and 3 surface characterization of acrylic resin surface on bond strength between silicone elastomer and acrylic resin.

Materials And Methods: 96 Cosmesil silicones bonded to heat-curing acrylic resin were fabricated with the dimension of 75 × 10 × 3 mm. The 3 primers used in this study were G611 platinum primer, A-330 Gold platinum primer, and cyanoacrylates resin.

A conservative treatment option for a single missing premolar using a partial veneered restoration with the SR Adoro system.

This report describes a step-by-step sequence for preparation for a posterior partial veneered restoration for a space closure using a Maryland bridge-design veneered with a heat-cured composite resin. The modality provides sound posterior occlusal function, combined with a psychological satisfaction to the patient of regaining a missing tooth. The preparation takes into account the design for resin-bonded prostheses.

Use of a matrix for apexification procedure with mineral trioxide aggregate.

This articles describes a technique for placement of a matrix barrier prior to use of mineral trioxide aggregate (MTA) as an artificial root-end barrier. The technique also demonstrates the use of a delivery system utilizing large-bore needles for the predictable and precise placement of the barrier materials at the apex of the tooth.

A new dimension to conservative dentistry: Air abrasion.

Air abrasion dentistry has evolved over a period of time from a new concept of an alternative means of cavity preparation to an essential means of providing a truly conservative preparation for preservation of a maximal sound tooth structure. The development of bonded restorations in combination with air abrasion dentistry provides a truly minimal intervention dentistry. This article reviews the development of air abrasion, its clinical uses, and the essential accessories required for its use.
