Objectives: The aim of the present study was to evaluate the effect of different framework designs according to the amounts of marginal facial cut back on the color and the fracture resistance of CAD/CAM titanium based metal ceramic restorations. Material and methods: Three naturalteeth were prepared one for each group to receive titanium based metalceramic crowns. A total of 15 titanium based metal ceramic crowns weremachine milled and divided into three main groups (each of 5 crowns)according to the amount of facial cut back as follows: Group I: with zerofacial cut back. Group II: with 1 mm facial cut back. Group III: with 2mm facial cut back. The crowns of each group were seated on theircorresponding natural tooth for the color measurements test. The preparednatural teeth were duplicated to 15 epoxy resin die, one die for eachcrown sample for assessment of fracture resistance. Results: whencomparing between mean (ΔE) values ANOVA test showed a statisticallysignificant difference between the groups ,Group I showed thestatistically significant highest mean (ΔE) value (3.54 ± 0.26), whileGroup III showed the statistically significant lowest mean (ΔE) value(1.11 ± 0.43).However, there was no statistically significant differencebetween Group I and Group II; both showed the statistically significanthighest mean fracture resistance values (730.4 ± 108 N) and (666.1 ±108.5 N) respectively, while Group III showed the statistically significantlowest mean fracture resistance value (377.2 ± 85.9 N).Conclusions: In ametal ceramic system, a framework reductions of 1 mm improveesthetic without affecting fracture resistance. Metal ceramic crownswith 2 mm framework reduction improve esthetic more than 1 mmframework reduction. Fracture resistance decreased dramatically with a 2 mm framework reduction.
