Primary teeth are the valuable assets of a child. Apart from the obvious function of delivering esthetics, their most important function is space maintenance for the succeeding permanent teeth. At times, due to unavoidable pathological conditions, there is premature loss of primary teeth. Space maintainers can either be banded to the enamel surfaces of healthy adjacent teeth or to the surfaces of full coronal restorations, the most common ones being stainless steel crowns (SSCs) and zirconia crowns (ZCs). Due to esthetic demands, ZCs have started replacing SSCs and therefore, there needs to be data on the banding of space maintainers on ZCs and the bond strengths obtained on cementations. Thus, the present study planned to evaluate and compare the bond strengths obtained by the banding of stainless steel bands (SSBs) over SSCs and ZCs using type I glass ionomer cement (GIC) and self-adhesive resins.
Sixty primary right mandibular molars were divided into four groups, group I, with cementation of SSB on SSC with type I GIC; group II, with cementation of SSB on SSC with self-adhesive resin cement; group III, with cementation of SSB on ZC with type I GIC; and group IV, with cementation of SSB on ZC with self-adhesive resin cement.
The mean bond strength value of GIC as luting cements in group I is 1.13 ± 0.075 MPa. The mean bond strength value of self-adhesive resin as luting cements in group II is 1.70 ± 0.104 MPa. The mean bond strength value of GIC as luting cements in group III is 1.38 ± 0.100 MPa. The mean bond strength value of self-adhesive resin as luting cements in group IV is 2.06 ± 0.119 MPa.
The bond strength of self-adhesive resin was higher when SSB was cemented over SSC when compared with the bond strength of GIC when SSB was cemented over ZC.

乳牙是儿童的宝贵资产。除了具有明显的美观功能外,其最重要的功能是为后续恒牙保持间隙。有时,由于不可避免的病理状况,乳牙会过早缺失。间隙保持器可绑扎在健康邻牙的牙釉质表面或全冠修复体表面,最常见的是不锈钢冠(SSC)和氧化锆冠(ZC)。由于美观需求,氧化锆冠已开始取代不锈钢冠,因此,需要有关间隙保持器在氧化锆冠上绑扎以及粘结时获得的粘结强度的数据。因此,本研究计划评估并比较使用I型玻璃离子水门汀(GIC)和自粘结树脂将不锈钢带(SSB)绑扎在不锈钢冠和氧化锆冠上所获得的粘结强度。
60颗右侧下颌第一乳磨牙分为四组,第一组,用I型GIC将SSB粘结在SSC上;第二组,用自粘结树脂水门汀将SSB粘结在SSC上;第三组,用I型GIC将SSB粘结在ZC上;第四组,用自粘结树脂水门汀将SSB粘结在ZC上。
第一组中作为粘结水门汀的GIC的平均粘结强度值为1.13±0.075MPa。第二组中作为粘结水门汀的自粘结树脂的平均粘结强度值为1.70±0.104MPa。第三组中作为粘结水门汀的GIC的平均粘结强度值为1.38±0.100MPa。第四组中作为粘结水门汀的自粘结树脂的平均粘结强度值为2.06±0.119MPa。
当将SSB粘结在SSC上时,自粘结树脂的粘结强度高于将SSB粘结在ZC上时GIC的粘结强度。
