PURPOSE The use of temporary or permanent cements in fixed implant-supported prostheses is under discussion. The objective was to compare the retentiveness of one temporary and two permanent cements after cyclic compressive loading. MATERIALS AND METHODS The working model was five solid abutments screwed to five implant analogs. Thirty Cr-Ni alloy copings were randomized and cemented to the a...

Purpose: This study investigated whether the bonding of a resin inlay to enamel and dentin could be improved by applying both an adhesive system and a low-viscosity microfilled resin to the underlying tooth substrate. Materials and Methods: A self-etching primer system (Clearfil SE Bond) and a low-viscosity microfilled resin composite (Protect Liner F) was applied to one half of enamel or denti...

This article describes a 16-year-old male who was referred to the Prosthodontics Department due avulsion of right upper central incisor and fracture left incisor; avulsed tooth lost at accident site. The patient refused have his teeth prepared except for broken so single cantilever retainer denture bridge made with fiber post design ovate pontic. Radiographic examination performed evaluate apic...

AIMS The purpose of this study was to investigate the reinforcement effect of short E-glass fiber fillers on some mechanical properties of temporary crown and bridge (TCB) composite resin with a semi-interpenetrating polymer network (semi-IPN). METHODS AND MATERIALS Experimental temporary fiber reinforced (TFC) composite resin was prepared by mixing 15 wt% of short E-glass fibers (3 mm in len...

PURPOSE The aim of this study was to determine the static load-bearing capacity of endodontically treated maxillary incisors restored with post-core complex made of experimental fiber composite resin (FC) and complete crown made of particulate filler composite (PFC). Further aim was to evaluate the effect of FC resin on the failure mode of the restoration. MATERIAL AND METHODS The experimenta...

PURPOSE The aim of this study was to evaluate the effects of abutment diameter, cement type, and re-cementation on the retention of implant-supported CAD/CAM metal copings over short abutments. MATERIALS AND METHODS Sixty abutments with two different diameters, the height of which was reduced to 3 mm, were vertically mounted in acrylic resin blocks with matching implant analogues. The specime...

This study evaluated the effect of chairside and laboratory types of surface conditioning methods on the adhesion of dual-cure resin cement with MDP functional monomer to zirconia ceramic after thermocycling. Disk-shaped (diameter: 10 mm, thickness: 2 mm) Y-TZP ceramics (Lava, 3M ESPE) were used (N=40) and finished with wet 1200-grit silicon carbide abrasive paper. Specimens were randomly divid...
