This incision extends from the of the palate to minimize the risk of hemorrhage associated with mesial aspect of the palatal root of the maxillary frst molar as far traumatization of the major palatine artery during harvesting of anteriorly as needed, depending on the amount of donor tissue the graft. The rationale for using this via a partial-thickness incision; the periosteum is left intact. A technique is that sounding of the palate reveals a limited amount second anterior/posterior horizontal partial-thickness incision is of connective tissue beneath the palatal mucosa. In contrast to traced parallel to the frst incision at a position closer to the the tuberosity area, where connective tissue occupies the whole midline. The two connective tissue exists between the coronal epithelium and horizontal incisions are connected via anterior and posterior verti- apical adipose tissue (see Figure 27-3, B). Use of the deep palatal cal partial-thickness incisions on the mesial and distal aspects of harvest technique (as in Step 4B) is often contraindicated in the graft.
