According to Takei and Coll. (1985), the problem post-operatively the most common techniques related transplants, the rejection is immediate, partial or total implant materials. In most cases, the cause is related to a surgical technique resulting in incomplete coverage of the tissue graft material in the interproximal areas. Although apparently there was an approximation of tissues during the laying of sutures, tissue shrinkage due to the healing will often strip the material of the graft during the postoperative period. Because of the difficulties observed, they developed a technique of preservation of papillae in order to use them in combination with bone grafts and synthetic materials in cases of periodontal bone defects (Takei HH, Han TJ, Carranza FA Jr, Kenney EB Flap technique for periodontal bone implants. J Periodontol 1985; 56:204-210).
In 1949, Schluger was one of the first researchers to describe the principles of surgical resection associated with bone bone remaining cases for which we could establish physiological contours without attachment loss, eliminate craters and interdental intrabony defects in to eradicate periodontal pockets and to achieve gingival architecture and physiological bone after surgery (Schluger SA basic principle in periodontal surgery.
