口内修复通常涉及将复合材料粘合到断裂的瓷上，较新的粘合剂系统，目前称为多用途系统，包括推荐的瓷修复程序的材料。本实验室研究评价了ProBond粘合剂系统的各种治疗方案。使用了三种不同的瓷表面程序：（1）用氧化铝（50 μ m）空气研磨，（2）8%氢氟酸，和（3）空气研磨和氢氟酸。然后使用8种不同的处理程序将10个复合圆柱体粘结到每组的瓷表面。在37摄氏度的水中储存24小时后，以及储存和热循环3个月后，用Instron试验机测定剪切粘结强度（以兆帕计）。在粘结复合材料之前，在瓷表面上的空气磨损和氢氟酸的组合记录了最一致的有效粘结强度。空气磨损组中的四种治疗方案在3个月时产生低粘结强度，该研究还表明，硅烷处理的瓷是关键的发展合适的复合材料的粘结强度。
Intraoral repairs often involve bonding composite to fractured porcelain, Newer adhesive systems, currently referred to as multipurpose systems, include materials with recommended procedures for repair of porcelain. This laboratory study evaluated various treatment regimens with the ProBond adhesive system. Three different porcelain surface procedures were used: (1) air abrasion with aluminum oxide (50 mu m), (2) 8% hydrofluoric acid, and (3) air abrasion and hydrofluoric acid. Eight different treatment procedures were then used to bond 10 composite cylinders to porcelain surfaces in each group. Shear bond strengths (in megapascals) were determined with an Instron testing machine after storage in water for 24 hours at 37 degrees C and after 3 months of storage and thermocycling, The combination of air abrasion and hydrofluoric acid on porcelain surfaces before bonding composite recorded the most consistently effective bond strengths. Four of the treatment regimens in the air abrasion groups yielded low bond strengths at 3 months, This study also indicated that silane treatment of porcelain is critical for development of suitable bond strengths for composite.
