RESEARCH ARTICLE The Influence of Impression Material on the Accuracy of the Master Cast in Implant Restorations Spyridon Stefos, Stefanos Kourtis, Aspasia Sarafianou and Panagiotis Zoidis Department of Prosthodontics, Dental School, University of Athens, Thivon Str 2, Athens, Greece Department of Restorative Sciences, Division of Prosthodontics, College of Dentistry, University of Florida, Gainesville, FL, USA 
The influence of impression coping splinting on the accuracy of the open-tray technique.
TLDR
The results suggest that there is no clinical advantage in splinting the impression copings for parallel implants and, on the other hand, when the implants are not parallel,splinting of the impressionCopings can result in greater accuracy of the fabricated cast. Expand
Effect of previous irrigation with chlorhexidine on the push-out bond strength of a calcium silicate-based material.
TLDR
Irrigation with CHX prior to furcation repair did not result in a statistically significant difference, compared to the use of DW, in the push-out bond strength of Biodentine. Expand

A laboratory investigation of the accuracy of the repositioning impression coping technique at the implant level for single-tooth implants.
TLDR
This study investigated the accuracy of the repositioning impression technique at the implant level using vinyl polysiloxane impression material using senior dentists, postgraduate students and technicians to record the position of an implant in a master model. Expand
Accuracy of implant impression techniques.
TLDR
The technique using acrylic resin to splint transfer copings in the impression material was significantly more accurate than the two other techniques and was discussed with suggestions to improve clinical and laboratory techniques. Expand
Accuracy of impression techniques for implants. Part 1--Influence of transfer copings surface abrasion.
TLDR
This study evaluated the influence of surface abrasion of transfer copings to obtain a precise master cast for a partially edentulous restoration with different inclinations and found technique TA presented more accurate master casts than TRS and TAA techniques. Expand
Evaluation of the accuracy of three techniques used for multiple implant abutment impressions.
TLDR
Improved accuracy of the master cast was achieved when the impression technique involved square impression copings joined together with autopolymerizing acrylic resin or square impressionCopings that had been airborne particle-abraded and adhesive-coated. Expand
The Significance Of Passive Framework Fit In Implant Prosthodontics: Current Status
TLDR
The clinical significance of passive fit and the factors that affect the final fit of implant-supported frameworks are reviewed. Expand
Impression techniques for implant dentistry
The object of making an impression in implant dentistry is to accurately relate an analogue of the implant or implant abutment to the other structures in the dental arch. This is affected by use ofExpand
A comparison of the dimensional accuracy of the splinted and unsplinted impression techniques for the Bone-Lock implant system.
TLDR
The splinted technique exhibited more deviation from the master model than the unsplinted techniques did, primarily associated with rotational discrepancies around the long axes of the implants for the splinting technique. Expand
Effect of implant angulation, connection length, and impression material on the dimensional accuracy of implant impressions: an in vitro comparative study.
TLDR
The angulation of the implants may cause strains of impressions, probably because of the higher forces required for the impression removal, and undercuts negatively affected the impression accuracy. Expand
Accuracy of replacing three tapered transfer impression copings in two elastomeric impression materials.
TLDR
It was found that no one coping could be replaced into the impressions accurately and consistently by all five operators, however, there were significant differences in replacement accuracy between the three copings. Expand
A comparison of dimensional accuracy between three different addition cured silicone impression materials.
TLDR
Comparison of measurements indicated that any change in measured dimensions occurring during impression making, was compensated for in some way by the casting process. Expand
