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...

This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...

The aim of this study was to evaluate predoctoral complete denture curricula in the dental schools of Turkey in terms of materials, techniques, and approaches. A questionnaire with twenty-two multiple-choice questions was prepared and sent by e-mail to the directors of the prosthodontic departments of the seventeen long-established dental schools in Turkey. All schools responded for a response ...

OBJECTIVES Head and neck cancer patients who have lost facial parts following surgical intervention frequently require craniofacial implant retained facial prostheses for restoration. Many craniofacial implant patients require computed tomography and magnetic resonance imaging scans as part of their long-term follow-up care. Consequently removal of implant superstructures and peri-abutment tiss...

STATEMENT OF PROBLEM Little peer-reviewed information is available regarding the accuracy and reproducibility of digitally fabricated casts compared to conventional nondigital methods. PURPOSE The purpose of this in vitro study was to compare the accuracy and reproducibility of a digital impression and cast fabrication with a conventional impression and cast fabrication. MATERIAL AND METHOD...

Background:
 Dental impressions become contaminated with micro-organism from patient’s saliva and blood which can cross-infect stone cast poured against them. The aim of the present study was to compare efficacy commercially available disinfection products, one containing glutaraldehyde, sodium hypo chloride ethanol for material.
 Methods: For this investigations, dental impression 60...

PURPOSE The aim of this study was to compare the accuracy of casts produced by 2 impression techniques and elastomeric impression materials commonly used for the fabrication of implant-supported fixed prostheses. MATERIALS AND METHODS A master model with 4 synOcta ITI implants placed unilaterally in place of the mandibular right central incisor, canine, first premolar, and first molar was con...

Introduction: Flabby or fibrous ridge is one of the consequences of long term wearing of complete dentures. It can develop where hyperplasic soft tissue replaces the alveolar bone and is a common finding, particularly in the upper anterior region of long term denture wearers. Forces exerted during impression making can result in distortion of the mobile tissue unless managed appropriately; such...
