[Comparative characteristics of long-term results of using bioplant and colapol-KP3 and methods of managing bone wounds under a blood clot in surgical treatment of chronic periodontitis and periradicular cysts].

Use of colapol-KPZ manufactured by Polistom Firm (Moscow) in operations on the jaw bones (resection of the root apex, cystectomy) promoted a 1.75 times sooner repair of the bone than bioplant. In addition, colapol-KPZ prevented postoperative complications and relapses. Filling of bone defect with blood clot in resections of large cysts (a zone of 2 and more teeth) is ineffective, as it decelerates bone regeneration and leads to relapses in remote periods after surgery.
