This case report describes a simple method for identifying the citizenship of a denture wearer by marking the telephone country code number inside the denture base. A wax pattern for the denture framework was prepared on the refractory cast. A piece of embossing tape, containing the country code (81, Japan), Japanese prefectural code, and abbreviation of the dental clinic where the denture was ...

Since luting cement is used for fixing cast restorations to their abutments, the cement surface at the junction between cast and tooth is exposed to oral environment. The conventional cement so far used does not adhere to the tooth and is slightly soluble into saliva and gingival fluid1,2). Consequently, the microleakage and subsequent recurrent caries seem to develop at this junction. Recently...

Chemical cleansing by denture cleansers is the first choice for denture plaque control of tissue conditioners. This study evaluated the influences of denture cleansers on the surface quality of tissue conditioners by determining surface roughness and porosity. Three tissue conditioners (Hydro-Cast, SR-Ivoseal, Visco-Gel) and 3 types of denture cleansers (Pika [enzyme type], Polident [neutral pe...

Dental impressions disinfection is important to reduce the risk of cross contamination but this process may produce dimensional distortions. Peracetic acid is a disinfectant agent with several favorable characteristics yet underutilized in Dentistry. The aim of this paper is to compare the dimensional stability of casts obtained from addition silicone and polyether impressions that were immerse...

This was a retrospective, longitudinal cephalometric and cast study of 29 white patients at pretreatment, posttreatment, and an average of 6 years 3 months postretention. The goal was to assess changes with treatment and retention with the expanding mandibular lingual arch appliance in conjunction with fixed edgewise treatment. Seven mandibular cast measurements were assessed, including arch cr...

OBJECTIVE To determine retraction and alignment of protruded and rotated premaxillary segment and to measure increase in columellar length by using modified orthopaedic plate with anterior acrylic ring in newborn babies with non syndromic bilateral cleft lip and palate. METHODS Pre surgical infant orthopaedic treatment of ten non syndromic bilateral cleft lip and palate new born babies was do...

CaptekTM (capillary technology) is an advanced metallurgic system that was developed to combine optimal natural esthetics of dental porcelain with the strength of ceramometal , to produce accurate restorations on all types of tooth preparation and provide a biocompatible environment for the oral tissues in simple and affordable procedures. CaptekTM restorations include inlays, onlays, crowns, a...

This article deals mainly with the development of dental casting techniques and formulation of the different groups of alloys used in the fabrication of ceramo-metal restorations. It is recognized that in order for the quality of dental cast restorations to be improved, having alloys with the proper composition is not enough. Biocompatibility, good mechanical and physical properties, longevity ...

PURPOSE The purpose of this study was to evaluate the effects of the surface treatment and shape of the dental alloy on the composition of the prosthetic work and its metallic ion release in a corrosive medium after casting. MATERIALS AND METHODS Orion Argos (Pd-Ag) and Orion Vesta (Pd-Cu) were used to cast two crowns and two disks. One of each was polished while the other was not. Two as-rec...

This study was designed to clarify the three dimensional features of naso-maxillary complex in cleft lip and palate (CLP) by using computed tomography (CT) and to examine its change following an upper dental arch expansion. Sequential CT images with 2mm-thickness were obtained for 11 unilateral CLP boys (UCLP), 6 bilateral CLP boys (BCLP) and 4 boys without cleft (non-cleft). Additionally, two ...
