Sažetak
Endodontic procedure requires removal of the pulp tissue and necrotic dentine, as well as a significant amount of healthy hard dental tissue, which results in reducing the resistance of the tooth to the occlusal loading forces. Restoration of such a tooth needs to satisfy requirements for retention of the restorative material, its resistance, as well as the resistance of the remaining dental tissue to occlusal forces, good coronal and intraradicular obturation and also aesthetic requirements.
Postendodontic treatment includes the following procedures: replacement of lost tissues using alloplastic materials directly or indirectly (amalgam, composite resin and glass-ionomer cement fillings or inlay, onlay or overlay restorations); the alloplastic material crown restorations using intracanal posts and parapulpal pins; the alloplastic material core buildup with or without intracanal posts and parapulpal pins covered with prosthetic crown; restoration of lost tooth structure using laboratory made post and core covered with prosthetic crown. Sealing of endodontic cavity using one of the alloplastic materials would be the treatment of choice in uncomplicated cases, whereas in severely damaged teeth ensuring remaining tooth structure by vertical stabilization and the prosthetic crown would be necessary. The choice of procedure depends on the severity of crown damage, the tooth position in the arch, occlusal contacts, morphology of root canal spaces, functional and aesthetic aspects, financial ability and available time for performing the procedure.
The correct indication evaluation respecting all steps of the chosen procedure will provide long term survival of the postendodontically treated tooth in the stomatognathic system.
