Abstract
The use of intraoral block grafts is a valid treatment alternative for the regeneration of maxillary and mandibular horizontal bone defects. However, there is currently no consensus among different authors on the choice of the best type of intraoral bone block to use. Therefore, this update seeks to compare bone gain, post-operative complication rate and grafting success between autologous mandibular ramus and chin bone block grafts. The bone gain achieved is similar in both block grafts. However, a higher gain can be observed by CBCT when using mandibular ramus blocks. In addition, the rate of bone resorption is lower with ramus grafts. Implant survival is comparable in both types of grafts. The complications that occur, in order of frequency, are sensory alterations, pulp necrosis, dehiscence and bleeding, appearing more frequently in chin blocks. In addition, the recovery period in the mandibular ramus areas is slower. Thus, when choosing, it seems reasonable to individualize the case and take into consideration aspects such as morbidity and access to the donor area.
