Popis:	Statement of problem. The precise transfer of intraoral relationships of implants to laboratory working models is central to the success of implant prostheses. Purpose. In this study a stone master model incorporating five implants (Bone-Lock) was used to compare the dimensional accuracy of a splinted impression technique with an unsplinted impression technique. Methods. A three-factor analysis of variance was used to examine the effect of technique, relative position of the implant on the cast, and plane of measurement. Results. All three factors had a significant effect on dimensional accuracy. Conclusions. The splinted technique exhibited more deviation from the master model than the unsplinted technique did. This was primarily associated with rotational discrepancies around the long axes of the implants for the splinted technique. (J Prosthet Dent 1997;77:68-75.)
