This study evaluates retrospectively the survival rate of all-ceramic restorations, cemented using AWB technique (test) compared to those cemented with conventional technique (control)

A retrospective study on ceramic restorations, placed in the period 2003-2014, will be performed to assess the survival rate of all-ceramic restorations cemented adhesively. The effectiveness of cementation largely depend on the method used. The Air-Water-blasting performed prior to conventional acid-etch of dental tissues offers an increase in bond strength compared to the conventional etching technique.

Inclusion Criteria:

• patients who received at least one ceramic restoration

Exclusion Criteria:

• patients who received feldspathic ceramic restorations

all patients treated for bonded all-ceramic restorations between years 2003-2014
