Abstract
BACKGROUND

The odontogenic jaw cyst is a cavity containing liquid, semifluid or gaseous components, with the development of the disease. In recent years, with the rapid development of oral materials and the transformation of treatment of jaw cysts, more options are available for treatment of postoperative bone defect of jaw cysts. Guided bone regeneration (GBR) places biomaterials in the bone defect, and then uses biofilm to separate the proliferative soft tissue and the slow-growing bone tissue to maintain the space for bone regeneration, which is widely used in the field of implantology.

AIM

To observe the clinical effect of GBR in repairing bone defect after enucleation of small and medium-sized odontogenic jaw cysts.

METHODS

From June 2018 to September 2020, 13 patients (7 male, 6 female) with odontogenic jaw cysts were treated in the Department of Oral Surgery, Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine. Adults without hypertension, heart disease, diabetes or other systemic diseases were selected. The diagnosis was based on the final pathological results: 11 cases were diagnosed as apical cysts, one as primordial cyst, and one as dentigerous cyst. The lesions were located in the maxilla in seven cases, and in the mandible in six cases. All cases were treated with the same method of enucleation combined with GBR.

RESULTS

Three to four months after the operation, the boundary between the implant site and the surrounding normal stroma was not obvious in patients with small-sized odontogenic jaw cysts. The patients with tooth defects were treated with implant after 6 mo. For the patients with medium-sized odontogenic jaw cysts, the density of the center of the implant area was close to the normal mass at 6 mo after surgery, 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 mo after surgery. Patients with tooth defects were treated with implants at > 6 mo after the operation.

CONCLUSION

Enucleation combined with guided bone regeneration in small and medium-sized odontogenic jaw cysts can shorten the time of osteogenesis, increase the amount of new bone formation, reduce complications, and improve quality of life.

Keywords: Enucleation, Bone defect, Guided bone regeneration, Small and medium-sized, Odontogenic jaw cysts

Core Tip: This was a retrospective study to observe the clinical effect of guided bone regeneration (GBR) in repairing bone defect after enucleation of small and medium-sized odontogenic jaw cysts. The application of odontogenic jaw cysts extraction combined with GBR can shorten the time of osteogenesis, increase the amount of new bone formation, reduce complications, and improve quality of life. GBR has good prospects for application in the treatment of small and medium-sized odontogenic jaw cysts.
