Application Study of Enucleation Combined with Guided Bone Regeneration in Small and Medium-Sized Odontogenic Keratocyst

Yiting Cao, Yubo Wu, Qinghua Gu, Qian Jiang

To observe the clinical effect of guided bone regeneration (GBR) in repairing bone defect after enucleation of small and medium-sized odontogenic keratocyst. 13 patients with odontogenic keratocysts were treated in the Department of Oral Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. 11 cases were diagnosed as apical cysts, 1 case was diagnosed as primordial cyst, 1 case was diagnosed as dentigerous cyst. All cases were treated with the same method of enucleation combined with GBR. Three to four months after operation, the boundary between the implant site and the surrounding normal stroma was not obvious in patients with smallsized odontogenic keratocyst . The patients with tooth defect were treated with implant after 6 months. For the patients with medium-sized odontogenic keratocyst, the density of the center of the implant area was close to the normal mass at 6 months after operation, and there was a clear boundary between the periphery of the implant area and the normal mass. The boundary between the periphery of the implant area and the normal mass was blurred at 8 ~ 9 months after operation. Patients with tooth defect were treated with implant s at more than 6 months after operation. The application of odontogenic keratocyst enucleation combined with GBR can shorten the time of osteogenesis, increase the amount of new bone formation, reduce complications, and improve the quality of life. It has a good application prospect in the treatment of odontogenic jaw cyst. It is worthy of clinical application.
