Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
Introduction: The preparation in prosthodontics and especially in dental laminate veneers is very technically demanding.. Magnification improves the ability of the eye to resolve details and allows the clinician to see greater than it is possible with the eye alone. Aim:The study is to evaluate the impact of optical magnification on the precision of tooth preparation under simulated clinical conditions in digital manner. Material and methods: 40 plastic upper left incisors are divided into 2 groups- prepared with naked eye and with compound loups. Laboratory scanning device is used to scan the teeth both before and after the preparation and digital measurements are done to evaluate the accurateness of tooth preparation depending on the magnification. Results: The results show statistical difference in precision between naked eye and optical magnification. Conclusion: The preparation under magnification of loups is much more precise. Even though, in both groups the quantity of cut tissues it more than the supposed quantity which may affects the quality of the adhesive bond
