High accuracy dental impression is usually a first step during fabrication of indirect restorations that have to be seated in or on prepared teeth. The dimensional stability of the impression material could have an influence on the accuracy of the final restoration. Elastomeric materials (additioncured silicones and condensationcured silicones) are most frequently used as the impression materia...

INTRODUCTION Alginate is a versatile, irreversible hydrocolloid impression material, which is cost-effective and forms an essential component in dental practice. For elevating the hardness of the cast models, hardeners are combined with stone. Hence, we planned the present study to evaluate the impact of altering the time of contact between alginate and stone after various interim periods. MA...

AIM The aim of this study was to determine the wettability of different hydrophilic and hydrophobic elastomeric impression materials and the gypsum castability. MATERIALS AND METHODS The wettability was evaluated by determining the contact angles of different elastomeric impression materials. The contact angle was determined by placing a drop of aqueous solution of calcium sulfate dihydrate o...

The Effect of Equilibrating Master Casts On The Occlusal Harmony Of Cast Restorations (October 2008) Joe Meng, University of Montana; D.D.S., University of Iowa Chair of Advisory Committee: William W. Nagy PURPOSE: To determine the occlusal accuracy of mounted stone casts and the viability of a cast adjustment technique. MATERIALS AND METHODS: A dentoform mounted on an articulator served as the...

PURPOSE The objective was to evaluate canine positions, intercanine tip width (ICTW) and width of distal surface of canine (WDC), related to facial landmarks including interalar width (IAW), intercommissural width (ICoW), and distance between left and right projection lines drawn from inner canthus of eyes to alae of the nose (DPICa) in a group of Thai. MATERIALS AND METHODS One hundred Thai ...

Introduction: A study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. Many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. The aim of this study is to evaluate reliability and validity of dental measurement made on dig...

Developing human-centered agent architectures requires the integral consideration of architectural flexibility, teamwork adaptability, and context reasoning capability. With the integration of various forms of team intelligence including shared teamwork process and progress, dynamic context management and information dependency reasoning, and recognition-primed collaborative decision mechanism,...
