BACKGROUND Different factors such as impression techniques and materials can affect the passive fit between the superstructure and implant. The aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant definitive casts. MATERIALS AND METHODS Four internal hex implants (Biohorizons Ø4 mm) were placed on a metal maxilla...

in this article, three techniques for maxillo-mandibular relationship for replace-select implants are described. the use of healing abutments, planning abutments, and impression copings are presented, and the advantages and disadvantages are discussed.

Making an impression of the anophthalmic socket to facilitate the design of a custom made ocular prosthesis is a common practice. Different impression techniques can be used for its fabrication. The modified impression technique described here requires minimum laboratory procedures as the preliminary impression, secondary impression and wax trial can be done as a single stage procedure.

The history of complete denture impression procedures has been influenced largely by the development of impression materials from which new techniques and ideas arose. The purpose of this study was to compare the retention of complete dentures made by using different impression techniques like conventional, admixed, all green, and functional techniques. The results showed that there was signifi...

Introduction. One of the main steps of impression is the selection and preparation of an appropriate tray. Hence, the present study aimed to analyze and compare the accuracy of one- and two-stage impression techniques. Materials and Methods. A resin laboratory-made model, as the first molar, was prepared by standard method for full crowns with processed preparation finish line of 1 mm depth and...
