Background and Aim: Disinfection of dental impression materials can alter their dimensional stability, which in turn can affect the accuracy of dental casts. This study aimed to determine the effect of three disinfectants on the dimensional changes of ir-reversible hydrocolloid impression materials and addition silicones. Materials and Methods: Forty alginate and 40 addition silicone impressio...

STATEMENT OF PROBLEM Accurate recording of implant locations is required so that definitive restorations are properly supported and do not place additional stress on the implants. Angulated implants may result in inaccurate impressions, and the impression technique may affect the accuracy of the definitive cast. PURPOSE The purpose of this study was to determine the effect the combined intera...

OBJECTIVES The aim of this in vitro study is to evaluate the marginal and internal fit of zirconia core crowns manufactured following different digital and traditional workflows. METHODS A 6° taper shoulder prepared abutment tooth was used to produce 20 zirconia core crowns using four different scanning techniques: scanned directly with the extraoral lab scanner, scanned with intraoral scanne...

background the purpose of this study was to examine the relationship between the type of inhaled medication, length of use, dosing, the inhaler use technique and the severity and duration of disease on the dental caries of asthmatic patients. objectives in the present study, the frequency of dental caries in the asthmatic patients and control group was examined. in addition the possible associa...

The aim of this investigation was to describe the quality of prescription and fabrication of single-unit crowns by general dental practitioners in Wales. One hundred pre-piloted questionnaires were distributed to commercial laboratories in Wales with large catchment areas, and 20 pre-piloted questionnaires were distributed to the production laboratory at the Cardiff Dental Hospital. Information...

PURPOSE The aim of this study was to evaluate and compare the inter-operator reproducibility of three-dimensional (3D) images of teeth captured by a digital impression technique to a conventional impression technique in vivo. MATERIALS AND METHODS Twelve participants with complete natural dentition were included in this study. A digital impression of the mandibular molars of these participant...
