The incision is usually started at the disto-palatal line angle of the last molar and continued forward using a scalloped, inverse-beveled, partial-thickness incision to create a thin partial-thickness flap. For the correction of bone morphology (osteoplasty, osseous resection). It is the incision from which the flap is reflected to expose the underlying bone and root. The apically displaced flap provides accessibility and eliminates the pocket, but it does the latter by apically positioning the soft-tissue wall of the pocket.2 Therefore, it preserves or increases the width of the attached gingiva by transforming the previously unattached keratinized pocket wall into attached tissue. 4. Dr Teeth - YouTube It differs from the modified Widman llap in that the soft tissue pocket wall is removed with the initial incision; thus it may be considered an internal bevel glngivectomy.
