M.O.D Ceramic Onlay: A Case Study
The procedures done for the restoration of tooth number 45 were those of an all ceramic M.O.D onlay piece, and as described in the case study, the proposed treatment techniques conserves the remaining tooth structure, reestablishes function, offers satisfactory esthetics, and be considered as an alternative restoration.
For patients demanding aesthetic restoration, ceramic onlays provide a durable alternative to posterior composite resins. Dental ceramics are considered to be esthetic restorative materials with durable characteristics, such as translucence, fluorescence, and chemical stability.1,2 They are also biocompatible, have high compressive strength, and their thermal expansion coefficient is similar to that of tooth structure.3 Marginal leakage of the resin is reduced, because the luting layer is relatively very thin. A ceramic onlay is indicated for patients with a low caries rate, who have worn or carious teeth with intact......
