| Abstract | ||||
| “Effect of different Tooth Surface Finish on Marginal Adaptation of Laminate Veneers”-an In Vitro Study Aim: Assessment of marginal adaptation of laminate veneers after using three different diamond grit abrasives on natural teeth in sequence blue, blue and yellow, blue yellow and polishing tips in three groups. Methodology: Natural sound incisors were collected from Ain shams oral and maxillofacial surgery undergraduate clinic. Specimens were cleaned using ultrasonic scaler and low speed polishing tips. Teeth were then prepared using silicone index for standardization purposes to receive a butt joint veneer preparation; then secondary impression was taken for all the specimen then designed on EXOCADGMBH and milled using a ROLAND 5 axis milling machine. Afterwards lithium disilicate e.max processed in a Programat IVOCLARVIVADENT (P710) porcelain furnace. Veneers were then seated on the die using glycerin and placed on the measuring grid of digital microscope for measurement and statistically tabulated. Results: statistically significant difference between three tested groups showing improved marginal adaptability. Blue showed the highest marginal gap, yellow was second lowest and white polish group was lowest. Conclusion: Fine Polishing showed improved vertical marginal gap distance and marginal adaptation of laminate veneers. | ||||
