PDF: Bonding values of two contemporary ceramic inlay materials to dentin following simulated aging

Current popularity of tooth-colored restorations is a normal response to increased esthetic demands of dental patients.


Ceramic inlays were introduced to dentistry many decades back, however problems were encountered with the early types that have limited their application.

Several laboratory studies assessed factors responsible for early ceramic inlay failures. Brittle fracture, loss of retention, marginal inaccuracy and unsatisfactory esthetics of the air fired porcelain were reported to be common. However, the evolution of many strengthened ceramic systems with sensible levels of success refreshed the attention to using ceramic restorations.

Both glass-infiltrated and pressable glass ceramics were generally able to produce inlays with acceptable strength and fit. Lithium disilicate-based ceramics also showed similar ability to provide successful restorations.

In order to save operators’ and patients’ time, machinable techniques became popular and many types of ceramic blocks/disks are currently available for either chair-side or laboratory inlay fabrication.
