BACKGROUND This study was conducted to compare the linear dimensional accuracy of die materials before and after disinfection of the impression. Type IV and V conventional dental stone, type IV-resin impregnated and copper-plated die materials were studied. MATERIALS AND METHODS A stainless-steel master die analogs to a complete veneer crown preparation with three scribed lines (I: vertical, ...

BACKGROUND AND OBJECTIVES Biometric authentication is an important process for the identification and verification of individuals for security purposes. There are many biometric systems that are currently in use and also being researched. Tongue print is a new biometric authentication tool that is unique and cannot be easily forged because no two tongue prints are similar. The present study aim...

Computer-based digital orthodontic models have been developed that have the potential to replace dental casts. The aim of this study was to examine the accuracy and reproducibility of measurements made on digital models. Ten sets of orthodontic study models were scanned using the Arius3D Foundation System and three-dimensional (3D) images were produced by computer software. Two examiners indivi...

Intercanine width, intermolar width and arch length are essential for diagnosis and treatment planning and are closely related factors in orthodontics.The purpose of this study was to determine the correlation between these measurements and how these measurements are related to each other. Dental casts of 100 orthodontic patients (72 females and 28 males) with a mean age of 18.7 years (12-38 ye...

OBJECTIVE: To determine the frequency of patients with various anatomical forms hard palate for complete denture fabrication and to compare mean distortion in heat cure base polymer millimetres different forms. METHODOLOGY: Informed consent was taken from total seventy six divided into low medium Dental casts were prepared alginate impression poured type III stone reference point R marked on de...

Replacement of missing ears is a challenging task in which extensive array of materials and techniques have been employed. This article describes a different and simplified procedure for fabricating auricular prostheses very similar to the intact left ear of the patient. A 65-year-old male patient was referred to the Department of Prosthodontics with the loss of the right ear. In this case, the...

background: different factors such as impression techniques and materials can affect the passive fi t 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 defi nitive casts. materials and methods: four internal hex implants (biohorizons ø4 mm) were placed on a metal maxil...
