PURPOSE This review critically compares the available clinical and laboratory methods for assessing the fit of an implant prosthesis. MATERIALS AND METHODS MEDLINE and PubMed databases were searched for studies related to the fit of implant prostheses or the effect of misfit. Different combinations of key words were used. The screening procedure was(More)

This article describes a procedure for fabricating an optimal provisional restoration before tooth preparation. The procedure involves the fabrication of an indirect-direct provisional fixed partial denture. There are several advantages to this procedure, such as reduced chair time, less heat generated in the mouth, reduced contact between resin monomer and(More)
BACKGROUND The authors reviewed and compared gingival retraction techniques used for implants and teeth. TYPES OF STUDIES REVIEWED The authors searched the literature using article databases Ovid MEDLINE up to May 2008, PubMED and Google Scholar (advanced search) and the following search terms: gingival retraction, implant abutment, impressions,(More)
Titanium implants are widely used in the orthopedic and dentistry fields for many decades, for joint arthroplasties, spinal and maxillofacial reconstructions, and dental prostheses. However, despite the quite satisfactory survival rates failures still exist. New Ti-alloys and surface treatments have been developed, in an attempt to overcome those failures.(More)
PURPOSE The aim of this study was to review the published literature investigating the accuracy of fit of fixed implant frameworks fabricated using different materials and methods. MATERIALS AND METHODS A comprehensive electronic search was performed through PubMed (MEDLINE) using Boolean operators to combine key words. The search was limited to articles(More)
OBJECTIVE To identify the techniques most commonly used in New Zealand for gingival retraction for impressions of natural teeth and implants in fixed prosthodontics. DESIGN Postal survey of a random sample of dentists METHODS A questionnaire was mailed to all members of the New Zealand Dental Association (NZDA). Data were analysed using SPSS. RESULTS(More)
STATEMENT OF PROBLEM The human mandible flexes during different jaw movements. Mandibular flexure is known to be restricted when natural dentition is restored with long-span fixed prostheses, but its effect on implant-supported fixed prostheses is unknown. Restriction of mandibular movement by implant-supported fixed prostheses may lead to excess strain(More)
BACKGROUND Computer numeric controlled (CNC) milling was proven to be predictable method to fabricate accurately fitting implant titanium frameworks. However, no data are available regarding the fit of CNC-milled implant zirconia frameworks. PURPOSE To compare the precision of fit of implant frameworks milled from titanium and zirconia and relate it to(More)
PURPOSE The aims of this review are to determine the effect of mandibular flexure on the "implant-framework system," and analyze the existing literature on the topic. MATERIALS AND METHODS A MEDLINE and PubMed search was conducted to identify any articles in English related to the topic published up to May 2010 using the search words "mandible,""dental(More)
OBJECTIVE To determine the range and elemental composition of alloys used for PFM and crown-and-bridge restorations by New Zealand dental laboratories, and to understand the reasons for their selection. MATERIALS AND METHODS Two waves of data collection were carried out via post and telephone interview. The source population was dental laboratories(More)
