PERBEDAAN KEKUATAN GESER ANTARA SELF ADHESIF SEMEN DAN SEMEN IONOMER KACA TIPE 1 TERHADAP RESTORASI INDIRECT VENEER RESIN KOMPOSIT NANOHYBRID
Abstract
Indirect venneer is a laminate restoration that make in dental laboratory for correct tooth discoloration by improve the shape, size, and color of the tooth. Veneer divided into two type which made from percelain and composite resin. The composite resin veneer is common material for veneer because of the price is cheaper than porcelain while strong enough for usable. Nowadays, the materials type of composite resin that well know for fabricated the veneer is nanohybrid composite resin because it has good mechanical strength and good estheti for anterior teeth. Indirect veneer is one in two technique of veneering which can’t bond with tooth surfeace directly, so the veneer need to use cementation material adhere to the tooth. Self adhesive and glass ionomer cement type 1 is cementation materials which the most widely used for indirect veneer..
Aims : To study the differences of shear bond strength between self adhesive cement and glass ionomer cement type 1 to nanohybrid composite resin indirect veneer restoration.
Research Design: This study is experimental laboratory. In this experiment, using 12 samples of maxillary premolar teeth of post-extraction. The samples was divided into 2 groups, for the first group used cself adhesive cement and the second group used glass ionomer cement type 1 as cementation materials. The data is processed with independent samples T-test with 95% significance level (P <0.05).
Result: there are any differences of shear bond strength between self adhesive cement and glass ionomer cement type 1 to nanohybrid composite resin indirect veneer restoration. Analysis with independent T-test show the result that there is a significant differences of shear bond strength of the adhesion of the veneer indirect nanohybrid composite between using self adhesive cement and glass ionomer cement type 1 as a cementation material which significance 0.000 (p <0.05).
Conclusion: there are any significant differences of shear bond strength between self adhesive cement and glass ionomer cement type 1 to nanohybrid composite resin indirect veneer restoration
