[ABSTRAK
Penelitian ini bertujuan untuk membandingkan kuat rekat geser dan AdhesiveRemnant Index (ARI) dua produk breket metal yang direkatkan dengan satu adesif.Dua puluh gigi premolar atas manusia ditanam pada silinder PVC dengan resinakrilik. Spesimen dibagi menjadi dua kelompok, kelompok A: breket metal 3B, Cina+ Transbond XT; kelompok B: breket metal Protect, Cina + Transbond XT (3M,Unitek, Amerika). Dihasilkan rerata kuat rekat geser 6,09 dan 7,91 MPa padakelompok A dan B (p<0,05) dan nilai ARI: 1 dan 2 pada kedua kelompok (p>0,05).Disimpulkan bahwa dua kelompok memiliki nilai kuat rekat geser yang berbedabermakna dengan kegagalan ikatan bersifat kohesifABSTRACT
The aims of this study were to compare in vitro shear bond strength (SBS)and Adhesive Remnant Index (ARI) of two metal bracket products bonded with anadhesive material. Twenty human upper first premolar embedded in acrylic resin.Specimens were divided into two groups, Group A: 3B, China metal bracket +Transbond XT; Group B: Protect, China metal bracket + Transbond XT (3M,Amerika). The mean SBS for Group A and B were 6,09 dan 7,91 MPa and ARI: 1and 2 (p>0,05). It was concluded that the SBS of two groups was significantlydifferent with cohesive bond failure.;The aims of this study were to compare in vitro shear bond strength (SBS)and Adhesive Remnant Index (ARI) of two metal bracket products bonded with anadhesive material.
