M.O.D Ceramic Onlay, a Case Study
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 buccal and lingual cusps, caries lesions not to deep into the dentin; and patients wishing to restore the tooth to its original appearance. An onlay allows the damaged occlusal surface to be restored in the most conservative manner and enables the remaining enamel to be preserved.4 Due to the improvements of the materials, fabrication techniques and bonding systems, ceramic onlays have become popular to the public demands for esthetics, and as a durable restorative material. Among ceramic materials used today are feldspahtic porcelain, castable ceramics (DicorR) and new machine glass ceramic ( Dicor R DIGG) for use with CERECR system.
Clinical Report
Oral Diagnosis
Mrs. Prisclila M. Nirvaha, a 50 year old female patient, was referred to C.E.U dental infirmary for dental treatment. She had complained of having tooth sensitivity when drinking cold beverages but the sensitivity would immediately subside when stopped, of which was first observed approximately three months ago.
