A classification system for connective tissue graft incisions is proposed. It categorizes the design of the palatal incision into three classes. In addition to the basic classification, two subclasses are mentioned in this article. Additional descriptions are included to further define the incision design. The use of such a classification should assist future communication among clinicians and researchers. This article presents representative clinical cases to aid the clinician in applying the classification for incision design from the palatal site.
