Background: In 1980 Neyman and Karring conducted experimental studies using lab animals in which they observed that the gingival so= >ssue cells reproduced faster than the ones from the periodontal ligament. In 1988 Dahlin showed the possibility of guiding and increasing the osseous neo-forma>on using a membrane to inhibit the genera>on and reproduc>on of connec>ve >ssue cells, leEng the mul>poten>al osteoblasts cells reproduce. Objective: To fulfill the ridge augmenta>on using the GBR technique to obtain the suitable osseous thickness to place an implant-supported prosthesis. Case of Study: A 54 years old female pa>ent presents movement in teeth 11 and 12, X-ray revealed periodontal defects in both teeth. Extracc>on and augmenta>on ridge techique with GBR was planned.

Conclusion. The ridge augmenta>on was achieved and radiographically a con>nuity in the osseous trabeculated was observed with none interphase between the bone and the bone subs>tute acquiring osseous integra>on of the implants. Image 11,12,13,14. Image 10
