The authors present a clinical case of bone atrophy at the level of premolars of the 2nd Q, regenerated with autograft in a block collected from the mandible body (oblique line), xenograft, PRGF and collagen membrane fixed with metal pins.
Discussion: Various types of bone substitutes are available for this type of surgery. For many authors, the autograft is considered the ideal graft. In this case, given the great bone atrophy in thickness and height and the demanding aesthetic component (high smile line), exactly this type of graft was chosen. It has the inconvenience of the need for another surgical site, which can translate into more comorbidity. In any case, it is a very predictable procedure with good clinical results.
Conclusions: In the absence of quantity and quality of bone for rehabilitation with dental implants, the surgeon has available surgical techniques and varied bone substitutes. One of these techniques is the autograft, considered by many to be the “Gold Standard” of bone grafting. In this case and in view of the need for a significant horizontal increase, as well as the desirable vertical increase and the availability of intraoral donors, this type of graft was obtained. The result obtained is predictable and with very satisfactory results.
