D05.750.716.822.308

In this split-mouth study, each patient will receive two direct restorations made with two different composite resins, which will be divided into two groups: Control group - 30 patients will receive direct restorations in a posterior (molar or pre-molar) class I or II with composite resin Admira Fusion (Voco - Germany) by conventional tchnique; Experimental group: the same 30 patients will receive in another posterior tooth (molar or premolar) another direct restoration class I or II with the composite resin by bulk fill technique with Admira Fusion Xtra (Voco - Germany). The restorations will be allocated randomly for each tooth. Evaluations will be performed in the periods after 6, 12 and 24 months from the restorative procedure.

Procedure/surgery

Primary Outcome(s)

Clinical success rate after 24 months, evaluated by tactile and visual examination by clinical exam, given in percentage.

The success rate after 24 months for restorations with Admira Fusion composite resin was 100% and Admira Fusion Xtra was 96.15%. This difference was not significant.

Secondary Outcome(s)

Time necessary to perform the restoration with a timer, given in seconds.

The time necessary to apply the restorative material, make the sculpture, light-cure the increments and complete the restoration was higher for Admira Fusion than Admira Fusion Xtra. The results of t-test for independent samples showed significant differences between the groups.
