射孔修复的内部基质概念与传统技术相比具有明显的优势。生物相容性基质允许修复材料的控制。降低了修复材料放置的技术敏感性，并防止了修复材料受到出血的污染。在可到达的位置，可以预测地修复穿孔，相比之下，预后大大改善。更少的手术或手术改变牙齿将是必要的，从而降低治疗费用。如果防止手术改变牙齿，现有牙冠可以保留的比例更高。目前正在开发和研究的显微外科技术可能允许非手术修复无法触及的穿孔。因此，牙髓治疗的范围将会扩大。
The internal matrix concept of perforation repair offers distinct advantages over classic techniques. The biocompatible matrix allows control of the repair material. The technique sensitivity involved with placement of the repair material is reduced and contamination of the restorative material with hemorrhage is prevented. In accessible locations perforations can be repaired predictably and, by comparison, the prognosis is improved greatly. Fewer surgeries or surgical alterations of teeth will be necessary, thus reducing the cost of treatment. A higher percentage of existing crowns can be salvaged if surgical alteration of the tooth is prevented. Microsurgical techniques currently are being developed and researched that may allow nonsurgical repair of inaccessible perforations. The scope of endodontic therapy, therefore, will be expanded.
