Influence of heat treatment on the microstructure and the physical and mechanical properties of dental highly translucent zirconia.

Purpose: Microstructural and physico-mechanical characterization of highly translucent zirconia, prepared by milling technology (CAD-CAM) and repeated firing cycles, was the main aim of this study.

Materials And Methods: Two groups of samples of two commercial highly-translucent yttria-stabilized dental zirconia, VITA YZ-HT (Group A) and Zolid HT + White (Group B), with dimensions according to the ISO 6872 "Dentistry - Ceramic materials", were prepared. The specimens of each group were divided into two subgroups.

Dental Procedures in Patients with Atrial Fibrillation and New Oral Anticoagulants.

This review discusses the basic pharmacology of new oral anticoagulants that are used for prevention of thromboembolism in patients with atrial fibrillation. It presents available evidence, and provides recommendations for the management of patients requiring invasive procedures in dental practice.

Cement- and screw-retained implant-supported prostheses: up to 10 years of follow-up of a new design.

Purpose: This retrospective study investigated treatment outcomes over 10 years of a new prosthesis design in implant prosthodontics that uses a combined cement- and screw-retained principle.

Materials And Methods: The clinical data of 78 implant-supported prostheses were examined. Each prosthesis incorporated at least 1 screw-retained element and 1 or more cement-retained telescopic units.

Telescopic prostheses for implants.

This retrospective study investigated the outcome of 73 telescopic implant-supported fixed prostheses. Fifty-four prostheses were entirely cement-retained, and 19 incorporated a screw-clamping unit. The rate of complications was low and in most cases minor in nature.
