Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Prosthodontics Summary: Aim: The purpose of this study was to evaluate the degree of time dependent wear of antagonist natural enamel and patient satisfaction for zirconia reinforced lithium silicate when compared to monolithic zirconia crowns at 0,3,6,1 year follow up periods.Methodology: A total of 26 posterior teeth (7 females and 4 males) were selected for this study with an age range of 20-60. Then they were divided into two groups (1&2) according to the masking method (N=13). First group received monolithic zirconia crowns over posterior teeth up to two crowns per patient. Second group received zirconia reinforced lithium silicate crowns over posterior teeth up to two crowns per patient. Immediately after cementation of the restoration addition silicone impression were taken and epoxy model were poured.Then assessment of the restoration for patient satisfaction and shade matching was done postoperatively. Wear of enamel antagonist of the two groups were assessed using 3D Profilometer measured in micrometer through the epoxy model made after the follow up visits 3-6-12 month followed by evaluation of the Patient satisfaction of the two groups which were assessed using VAS (visual analogue scale questionnaire that collect history of reactions) which is represented by a scale from 1-10 Results: Repeated measures Analysis of Variance (ANOVA) was used to study the effect of ceramic type, time and their interactions on mean Ra. Bonferroni{u2019}s post-hoc test was used for pair-wise comparisons when ANOVA test is significant. For non-parametric data; Mann-Whitney U test was used to compare between the two ceramic types
