Rehabilitation of partially and completely edentulous patients with implant-supported prosthesis has become a widely accepted treatment option. The conventional Branemark system involves loading of the implants after 4-6 months of placement. This obvious disadvantage of the procedure leaves the patient with no teeth or with a removable temporary prosthesis, and hence, many patients, at times, do not choose this option at all. Dental implants, when placed in the basal bone, can be immediately loaded with teeth, as this bone is very strong, never gets resorbed throughout the life, and forms the...

Irreversible hydro colloid impression material is routinely used for the purpose of reproducing hard and soft intra oral tissues. The gypsum compatibility and the dimensional accuracy of the cast used to fabricate the cast are crucial for diagnostic and treatment planning purposes. In addition, the fabricated casts are valuable for the purposes of evaluating prosthetic space, diagnostic wax patterns for treatment planning and fabrication of resin based prostheses. Recently, several dental manufacturers have introduced electronic rotary devices to facilitate mixing of irreversible hydro...

This book gives an enhanced views about concept of platform switching. The concepts are explained under separate headings to make reader to grasp the knowledge without confusion.

It provides detailed evidences on crustal bone loss pattern around platform matching and switching implants and abutments. Hence,it is a textual treat to gain knowledge...

Bonding between the tooth and the prosthesis is very much important for the longevity of the prosthesis. Ever since composite came into play in dentistry, bonding agents have gained a greater level of popularity, since adhesion to the enamel and dentin is of prime importance in the restorative dentistry. With the introduction of the acid etching into clinical practice, various dentin bonding agents were developed to improve the quality of the restoration. In the aim of simplifying the bonding procedure, various authors attempted to develop new bonding agents thereby improving the quality of...

Venting, axial grooves and provision of axial cement space are methods that have been used to create space between the intaglio surface of crowns and the tooth preparation. The application of paint-on die spacer prior to waxing is the most popular method for providing this space.The use of die spacer can reduce the hydraulic pressure between the cement and restoration; hence it allows better seating of a cast restoration, decreases seating time and allows excess cement to escape.In addition, die spacer has been shown to improve the marginal fit between the restoration and tooth preparation,...
