Abstract Aim and Objective The main aim of this study was to evaluate the effect of three different types of pattern materials on the vertical marginal accuracy of complete cast crown. Material and Methods Three groups of 20 specimens each were made based on three pattern materials, that is, blue inlay wax, autopolymerizing acrylic resin, and light cure pattern resin. Castings were made and examined using stereo microscope for vertical marginal discrepancy. Results The result showed that the highest mean gap was noticed in the castings fabricated using inlay type B pattern wax followed by the castings fabricated using autopolymerizing resin and the least mean gap was observed in the castings fabricated using light cure modeling material. Conclusion It was concluded from this study that the use of light cure modeling material to make patterns for casting with lost wax technique is best recommended than inlay type B pattern and autopolymerizing resin.

ABSTRACT Aim The aim of this study was to comparatively evaluate the microroughness created on titanium alloy for use in dental implants subjected to two different acid etching techniques. Materials and Methods Commercially available grade 5 pure titanium plates were machine prepared into 26 plates measuring 3 × 1 cm × 5 mm for acid etching with hydrofluoric acid (HF) and dual acid etching technique using sulfuric acid (H2SO4) followed by hydrochloric acid (HCl). Twenty-five plates were divided into four groups based on the duration and sequence of acid etching. Upon completion of the acid etching procedure, the titanium plates were assessed for their surface characteristics by a surface profilometer. The average roughness parameters values Ra, Rq, Rz obtained for each titanium plate were compared against each other and with unetched titanium plate. Results The average roughness value Ra obtained was 0.480 μm for untreated surface and 3.65 μm maximum for the titanium plate etched for 72 hours in H2SO4 and 48 hours in HCl, which is about seven times the value of surface roughness on the unetched plates. The roughness values obtained after acid etching with HF for any duration were nonsignificant compared with the unetched plates. Conclusion The dual acid etching technique seems to be a simple method to develop a titanium implant surface, though evaluation of the biological response to this surface is necessary. Clinical significance The present study showed that by optimizing the parameters of acid etching, a rough titanium surface can be obtained similar to the various implant surfaces available commercially.
