Therapy of odontogenic cysts often requires a multidisciplinary approach in order to achieve successful therapy. The aim is maximum protection of the surrounding anatomical structures and protection of as many teeth which are affected by cystic as possible. The choice of bioactive materials in endodontic treatman enables regeneration, reparation of tissue. It also have bactericidal and bacteriostatic effect. As an integral part of bioactive materials, hydraulic calcium silicates also have the property of bioactivity, which means that they release ions that lead to tissue mineralization. The success rate of endodontic surgical procedures is higher with the use of bioactive materials in the therapy of odontogenic cysts. During a specialist examination, the patient was diagnosed with extensive periapical lightening in the area of the first quadrant by orthopantomogram analysis. The patient was referred for additional diagnostics, and the CBCT analysis of the maxilla revealed the presence of an extensive cyst in the region 11-17. Due to the extensiveness of the procedure, the indication was procedure under general anesthesia. Vital teeth 13 and 12 are preoperatively endodontically treated and filled with bioactive material (Ceraseal, Meta Biomed, Cheongju-si, Republic of Korea). An apicotomy was performed on tooth 13 due to external root resorption. The bone defect is filled with artificial bone (Straumann, Xeno Graft, Basel, Switzerland) and with PRGF resorptive membrane (Straumann, Jason membrane, Basel, Switzerland). One week after the procedure, on control examination the vitality of tooth 11 was lost , and endodontic therapy was performed. Three months after, a followup examination was carried out and a proper clinical finding was obtained. On the radiograph is visible restitution of the bone defect |
