ABSTRACT

Objective In recent years, digital processes like computer-aided design/computer-aided manufacture (CAD/CAM) have been implemented in dentistry. On the use and reporting of this technology by dentists, there is no published information. The goal of this study was to determine whether CAD/CAM technology had infiltrated Indian dentistry practices and to look into the relationship between various demographic parameters and respondents' answers about using or not using this technology. Materials and methods A sample of Indian dentists, both users and non-users of CAD/CAM, were sent about 500 online surveys. It sought to shed light on the usage style, materials, advantages, and limitations of CAD/CAM dentistry, as well as their perceived advantages and access hurdles. Statistical analysis was conducted to determine the impact of numerous demographic factors, including country of employment, dentist experience, educational attainment, and the nature of the job. Results There were 132 total replies that were finished. The majority of respondents didn't use any aspect of a digital workflow, and the biggest obstacles to using CAD/CAM were the upfront expenses and a lack of perceived advantages over traditional techniques. The likelihood of using CAD/CAM technology was highest among dentists who primarily performed private practice (P<0.0001). A third of users thought that their training was insufficient, even though the majority of users were either self-taught or schooled by firms. The majority of respondents (60.6%) believed that CAD/CAM would have a significant future role. Conclusion Most respondents said they had never used any aspect of a digital process. Although most dentists who responded to the study thought CAD/CAM would play a significant role in the future, the majority were still interested in integrating it into their workflow. Dentists continue to have certain concerns regarding the chairside CAD/CAM restorations' quality.

ABSTRACT

Introduction: It is important to construct the sprue in a way that ensures that the mold gets an appropriate supply of metal at the right speed. Many manufacturers now offer sprue designs that have not been advocated in textbooks or publications for their normal use. Aim: The goal of this research was to compare the sprue design's marginal fit to that of the other designs. Methods: During this investigation, we attempted to see whether the fabrication of metal copings could be improved. Three sprue designs were used in this research for the assessment of casting accuracy: normal cylindrical, funnel-shaped, and cuboidal or flattened sprue forms. Results: The mean marginal disparity of nickel-chromium (Ni-Cr) alloy copings made by three distinct brands was determined to be statistically insignificant. Conclusion: Within the limitation of the study, it was concluded that the marginal accuracy of metal copings fabricated with three different brands of Ni-Cr alloy did not reveal a statistically significant result. However, out of the three different sprue designs, that is, cylindrical, cuboidal, and funnel shape, the marginal accuracy of cylindrical and cuboidal sprue designs was found to be better than that of the funnel shape sprue design because the funnel shape sprue design is narrow at the point of attachment, thereby increasing the flow pressure and decreasing the turbulence of the molten metal.
