The objective of this case report is to introduce a simple technique for simultaneously taking a closed-mouth impression and functionally generated path (FGP) for a full coverage crown restoration. A monolithic zirconia crown was the restoration of choice. An alginate impression of the abutment tooth was taken to fabricate a custom-made closed-mouth impression tray covering the abutment tooth a...

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...

background and aims. several products have been marketed for disinfecting impression materials. the present study evaluated the effect of deconex, micro 10, alprocid and unisepta plus sprays on staphylococcus aureus and candida albicans transferred to alginate and polyvinylsiloxane impression materials. materials and methods. a total of 180 impressions of a maxillary model (90 alginate and 90 p...

abstract       background and aim: dimensional changes of the impression materials after disinfection is a serious problem in dentistry which could fail the treatment. the aim of this study is to determine the effect of three disinfectants:2% deconex,5.25% sodium hypochlorite and nanosil d2 ,on dimensional changes of bayer alginate.       materials and methods: this experimental study was condu...

AIM Relating the marginal fit of the castings, to the accuracy of the impression produced using laminated hydrocolloid impression technique, alginate and double-mixed polyvinyl siloxane. Basic objective of the study is to check the feasibility of the use of laminated hydrocolloid impression technique in the fixed partial denture. MATERIALS AND METHODS The precisely machined metal die was desi...

PURPOSE To investigate face and content validity of a draft measure to be used across Canada to assess physiotherapy students' performance in clinical education, through broad consultation with physiotherapy clinical instructors (CIs) across Canada. METHODS An online survey was used to collect input on the draft measure. In addition to demographics, the questionnaire included questions on the...

After decades of research highlighting the fallibility of first impressions, recent years have featured reports of valid impressions based on surprisingly limited information, such as photos and short videos.Yet beneath mean levels of accuracy lies tremendous variance-some snap judgments are well-founded, others wrongheaded. An essential question for perceivers, therefore, is whether and when t...
