Abstract

Abstract:

Objective

To evaluate the bone formation of immediate implant in combination with guided bone regeneration (GBR) technique in restoration of anterior teeth with apical cyst.

Methods

Twenty-nine residual roots in 20 patients who asked for implant treatment and had no surgical contraindications were included. The residual roots were extracted and cystectomy was performed, followed by immediate implant and GBR. The second stage surgery was performed 6 months later and restorations were cemented in 8 months postoperatively. One year follow-up was performed to observe the stability of the implants and crowns. X-ray was also taken to evaluate the bone loss around the implant.

Results

Only one implant was loose, the rest implants were demonstrated to have good clinical results without loosen, dislocation or collagen membrane exposure. The gingival margins around the implants were free from suppuration and porrhea. High patient satisfaction and good masticatory function were reported during the follow-up. X-ray showed bone resorption was less than 1.2 mm for one year and good calcification of implanted bone powders. The clinical successful rate was 96.6% in this study.

Conclusion

For the cases of anterior teeth apical cyst, apical cyst cystoectomy in combination with immediate implant surgery and GBR technique can be used as a reliable and effective method to reduce the absorption of alveolar bone and facilitate new bone formation.

Key words: Apical cyst, Immediate implant, Guided bone regeneration
