Within the scope of this study, it was observed that the mean facture strength of the samples with shoulder porcelain labial margins having metal coping design extending upto gingivoaxial line angle of the finish line was highest as compared to samples with shoulder porcelain labial margins having metal coping design 1mm short of gingivoaxial line angle & samples having porcelain fused to metal coping design with 0.4mm wide metal collar.
Aim: This article presents an overview about various simple techniques for fabrication of radiographic and surgical stents for implant placement. Background: Dental implantology is now a feasible option to conventional prosthodontics. A need for predictable prosthesis has resulted in the emergence of prosthetically guided implantology. A radiographic stent is used for evaluation and determination of the accurate position for implant placement during the planning and for identification of the accurate site for the placement of implants during the surgical procedure. Radiographic and surgical stents help in placement of the implants in a precise and predetermined position and angulation, along with minimizing unnecessary osteotomy, results in an accurate design of prosthesis, reducing the time for implant placement and trauma caused to the patients thus increasing their comfort. Conclusion: Using stents for implant placement helps achieve accurate position and angulation of implant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
