The aims of this study were to find out whether scoring in a rose-trellis pattern improved the stretch of mucoperiosteal flaps more than conventional scoring in the horizontal plane, and to consider its application in the closure of oroantral communications. Sixteen sections of cadaveric porcine buccal mucoperiosteum were removed from the molar region of the maxilla and mandible. A three-sided flap was raised in the subperiosteal plane, excised, and pinned to a cork board with the periosteal side facing upwards. Eight samples were scored in the horizontal plane (control) using lines perpendicular to the line of simulated advancement, and eight in a rose-trellis or criss-cross pattern. Scoring using a rose-trellis pattern yielded a mean increase in stretch of 24.3% (p=0.0003) when compared with the conventional method. Buccal advancement flaps are widely used to close oroantral communications, and scoring of the mucoperiosteum facilitates the stretching of the tissue over the defect. To be successful, defects should be fully closed to prevent contamination, and closure should be tension-free. In this study, scoring in a rose-trellis pattern increased the stretch of the tissue sample more than scoring in the horizontal plane. The rose-trellis technique therefore could aid the effective closure of oroantral communications.
