Introduction: In 2001, Cavex presented the first test results, which showed 5 days dimensional stability for Cavex ColorChange. More than 10 years we used this information to show our customers the high quality and stability of our products. In the meantime, our Research & Development department worked on improvements of the alginate impression materials. We formed close cooperation’s with supp...

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...

T ests for accuracy and other characteristics of elastic impression materials generally fall into one or more categories. These are: (1) Linear tests which measure the material itself (usually unidimensional) .le5 (2) Tests which depend upon the formation and measurement of gypsum dies made from the impression materials. In these tests, the dies are measured, not the impression material itself....

BACKGROUND The initial placement of orthodontic elastomeric separators can be uncomfortable and painful. Therefore, it is important to relieve this disturbing sensation to create a discomfort or pain-free orthodontic visit. The purpose of this study was to investigate the effect of a lidocaine/prilocaine topical anesthetic on pain and discomfort associated with the placement of orthodontic elas...

Among other factors, the precision of dental impressions is an important and determining factor for the fit of dental restorations. The aim of this study was to examine the three-dimensional (3D) precision of gypsum dies made using a range of impression techniques and materials. Ten impressions of a steel canine were fabricated for each of the 24 material-method-combinations and poured with typ...

Impression materials used in the analysis of bite marks are required to maintain their stability and integrity for extended periods. It has been observed that certain impressions taken of skin lose their properties with time, becoming sticky and unusable as evidence. The objective of this study was to investigate the onset of "stickiness" in two commonly used dental impression materials when br...

Purpose. For a precise fit of multiple implant framework, having an accurate definitive cast is imperative. The present study evaluated dimensional accuracy of master casts obtained using different impression trays and materials with open tray impression technique. Materials and Methods. A machined aluminum reference model with four parallel implant analogues was fabricated. Forty implant level...

BACKGROUND One of the frequent applications of elastomeric infusion pumps is postoperative pain management. In daily practice, the disposable pumps get refilled with modified medication combinations in the successive days; although, the accuracy of infusion rates is unknown to clinicians. OBJECTIVES Our aim was to evaluate the effect of repeated filling on the delivery rate accuracy of an ela...
