Restoration of endodontically treated tooth using BioHPP indirect restorative material: case series

Abstract

Endodontic therapy weakens the remaining tooth structure which demands their rehabilitation. Various treatment modalities exist for rehabilitation of severely debilitated endodontically treated tooth including Endocrown, Post and core and Richmond crown depending on the clinical situation. Post and core with Davies crown is a routine practice of rehabilitation of severely debilitated tooth. In endodontically treated tooth with inadequate inter-arch space, endocrown can be safely given, although, presence of atleast 2mm of circumferential enamel is necessary. In cases with inadequate inter-arch space and absence of adequate circumferential enamel, Richmond crown is indicated. Conventional materials for rehabilitation using these modalities have major disadvantage of their high modulous of elasticity which increases the chances of rehabilitation failure. BioHPP, a modified polyetheretherketone (PEEK) can safely replace the conventional materials because of striking advantage of its modulus of elasticity which is similar to that of tooth structure. This case series presents the clinical situation-based rehabilitation of endodontically treated tooth using BioHPP as restorative material. 1.5 years follow-up showed satisfactory results paving the way for higher success rates of endodontically treated tooth with BioHPP as material of choice.
