项目摘要

(1) Carboxylate temporary cement showed high ability to prevent microleakage and was effective temporary cement to prevent contamination of abutment teeth during the term from tooth preparation through luting of final restoration.(2) Carboxylate temporary cement adhered to abutment tooth surface decreased the bond strength of adhesive resin.(3) 2.5% ammonia solution showed excellent removing ability of carboxylate cement and had little influence on bond strength of adhesive resin. Therefore, ammonia solution is a practical solvent for carboxylate cement.(4) In case of surface treatment of abutment tooth with metal core, the overflowed metal primer/dentin primer onto undesirable area of abutment tooth affected the bond strength of adhesive resins. Appropriate procedure was necessary to achieve best performances of bonding systems.(5) The portable sandblaster using a compressed air cartridge can be used equivalently as conventional systems to improve the bond strength of adhesive resin to metal and enamel of abutment teeth. However, the bond strength to dentin was adversely affected by sandblasting for 4-META/TBBO resin.(6) The application of NaOCl solution to dentin surface in metal post cavity decreased the bond strength of 4-META/MMA-TBBO resin to dentin. The neutralization with 5% sodiumthiosulfate or 5% ascorbic acid and ultrasonic cleaning was most effective method to recover the bond strength of adhesive resin.(7) The reinforcement using metal post or polyethylene fiber was most effective method to improve the bonding durability of resin-bonded fixed partial denture using composite denture tooth as pontic. However, clinical evaluation implicates that those reinforcements are not necessary for all cases and the cavity preparation with alumina blasting was effective and sufficient in clinical cases.

(1)羧酸盐临时水泥具有较高的防止微渗漏的能力，是防止基牙从预备牙到最终修复期间污染的有效临时水泥。(2)羧酸盐临时水泥与基牙表面的粘结降低了粘结树脂的粘结强度。(3) 2.5%氨溶液对羧酸盐水泥的去除能力较好，对粘接树脂的粘结强度影响不大。因此，氨溶液是一种实用的羧酸盐水泥溶剂。(4)对金属牙芯基牙进行表面处理时，金属底物/牙本质底物溢出到基牙不需要的区域，影响粘接树脂的结合强度。适当的程序是必要的，以达到最佳性能的键合体系。(5)采用压缩空气筒的便携式喷砂机可与传统系统等效使用，提高基牙黏合剂树脂与金属和牙釉质的结合强度。喷砂对4-META/TBBO树脂与牙本质的结合强度有不利影响。(6) NaOCl溶液在金属桩腔牙本质表面的应用降低了4-META/MMA-TBBO树脂与牙本质的结合强度。5%硫代硫酸钠或5%抗坏血酸中和和超声波清洗是恢复粘接树脂结合强度最有效的方法。(7)复合义齿为桥体的树脂粘接固定局部义齿，金属桩或聚乙烯纤维加固是提高粘接耐久性的最有效方法。然而，临床评价表明，并非所有病例都需要这些强化，氧化铝爆破空腔制备在临床病例中是有效和充分的。
