15 صفحه اولMarginal Accuracy of Castings Fabricated with Ringless Casting Investment System and Metal Ring Casting Investment System: A Comparative Study.
BACKGROUND The thermal expansion of the investment can be restricted by the metal casting ring because the thermal expansion of the ring is less than that of the investment. The ringless casting procedure is in use in clinical dentistry, though there is little scientific data to support its use in fixed partial dentures. In this study, marginal discrepancy of castings produced with the ringless...
متن کاملMarginal accuracy of nickel chromium copings fabricated by conventional and accelerated casting procedures, produced with ringless and metal ring investment procedures: A comparative in vitro study.
BACKGROUND Conventional investing and casting techniques are time-consuming and usually requires 2-4 h for completion. Accelerated nonstandard, casting techniques have been reported to achieve similar quality results in significantly less time, namely, in 30-40 min. During casting, it is essential to achieve compensation for the shrinkage of solidifying alloy by investment expansion. The metal ...
متن کاملAn accelerated clinical chairside technique for casting overdenture attachment copings.
An accelerated technique for casting a direct-pattern post and core restoration for use in fixed prosthodontics has been previously described. Similar techniques for use in removable prosthodontics show potential for clinical use, specifically for the fabrication of radicular stud overdenture attachments and their corresponding copings. The procedure uses a chairside technique and readily avail...
متن کاملComparison of Patient’s Satisfaction Level with Complete Dentures Fabricated by Neutral Zone Technique and Conventional Technique
The objective of the study was to compare the satisfaction level of edentulous patients provided with complete dentures that were fabricated by either the neutral zone technique or the conventional technique. For this a quasi experimental comparative study (Phase 2 trial) was carried out at Department of Prosthodontics, Armed Forces Institute of Dentistry, Rawalpindi, Pakistan from September 20...
