Introduction: The maintenance of the alveolar ridge after tooth loss is very important for the installation of an osseointegrated dental implant and for the aesthetic result of the rehabilitation prosthesis. Regenerative surgery is often needed to recover the volume lost when a tooth is extracted. The blood clot that forms is very important in regenerative surgery because it allows the mesenchymal cells to differentiate into osteoprogenitor cells, which leads to bone regeneration. Objective: This case report compares the bone repair after dental extraction in the same patient via three different protocols and the healing in preparation for posterior implant placement. Case Report: A patient 50 year-old female required dental extraction of elements 15, 24 and 26 and prosthetic rehabilitation. The first technique used was tooth extraction and suture only, the second technique used exposedBoneHeal® polypropylene membrane after extraction, and the third technique usedBoneHeal membrane subperiosteally. After a few days, the subperiosteal membrane became exposed and it was not possible to keep it in position. However, the two regions in which the membrane was used obtained a greater increase in soft tissue. Conclusion: In our study case, the polypropylene membrane seemed to repair tissue.
