Figure 2. Hot melt adhesive-made flexible cast. The use of flexible casts and dies for the chairside fabrication of interim restorations has been reported to overcome the drawbacks of the direct technique and provide a safe and biocompatible fabrication process. Because of the elasticity of these casts, removing the interim restoration after complete setting is easy, and the integrity of the ca...

BACKGROUND Prosthodontic procedures involving dental impressions, stone casts, record bases and prostheses may cause transmission of microorganisms between the patient, the dentist, auxiliary staff and laboratory personnel. In recent times, microwave radiation has gained wider acceptance in the field of applied science and has been used to reduce concentrations of bacteria and fungi, to dry den...

Three implant impression techniques, using 3 different splinting materials, were assessed for accuracy in a laboratory model that simulated clinical practice. For group A, an autopolymerizing acrylic resin was used to splint transfer copings. In group B, a dual-cure acrylic resin was used, and for group C, plaster, which was also the impression material, was used. A metal implant master cast wi...

BACKGROUND Alveolar ridge augmentation procedures are often needed prior to implant placement or prosthetic rehabilitation. The purpose of this study was to develop a quantitative method to assess the clinical outcome of such procedures. METHODS Two volumetric methods, based on the volume difference between the pre- and postoperative ridge, were developed. Either a transparent vacuum stent ma...

occlusal rest (Fig. 5, B), and guiding planes (Fig. 5, C). If there are voids or irregularities, they are filled with monomer and powder with a paint brush. 9. Try-in the removable partial denture (Fig. 6) to ensure a proper adaptation of the resin coping (Fig. 7). The die spacer can be removed from the tooth with a cotton pellet soaked in die spacer thinner. Rinse the tooth several times befor...

introduction & objective: after urinary tract infection and prostatic disorders , the urine stones are the third common genitourinary diseases. demographic, environmental and genetic factors affect urine stone formation. the aim of our study is to survey epidemiologic factors in patients with urinary stones referring to educational hospitals of hamadan during 2010-2013.      materials & methods...

in this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. the results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. the...

objectives: this study aimed to assess the effect of storage time and temperature on dimensional stability of impressions made with cavex outline zinc oxide impression paste. materials and methods: a round stainless steel mold with five grooves (three horizontal and two vertical) was used in this in-vitro experimental study. cavex outline impression paste was prepared according to the manufactu...

Abstract Guided by cultural labor economics, the paper analyzes career paths of former actors from popular television soap operas, and addresses in particular, if under which conditions such serial engagements may function as a stepping stone for subsequent professional acting career. A novel database 396 German artists with detailed long-term biographical information is used quantitative empir...
