Summary

Different augmentation techniques has been proposed to resolve problem of hard and/or soft tissue ridge defects to enable dental implant placement. Guided bone regeneration GBR procedure is considered as an acceptable reliable surgical procedure for localized ridge augmentation. Exposure of the membrane used for the GBR is considered a major disadvantage of this procedure. In order to avoid such complication, various flap advancement techniques have been proposed such as Periosteal releasing incision,Double-Flap Incision,Coronally advanced lingual flap. The study compare between the flap advancement provided by Periosteal releasing incision,versus,Coronally advanced lingual flap in the treatment of class 1 ridge defect.

Conditions

  • Flap Advancement
  • Primary Wound Closure

Interventions

PROCEDURE

coronally advanced lingual flap

Full-thickness crestal incision will be made over the edentulous ridge followed by one full-thickness vertical incision on the buccal side. On the buccal side, full thickness mucoperiosteal flap will be raised with horizontal incision 1-3 mm in depth performed in the buccal flap. On the lingual side, a full-thickness mucoperiosteal flap will be elevated until reaching the mylohyoid line. A band of mylohyoid muscle is inserted into the inner part of the lingual flap approximately 5 mm from the crest in an apical direction. A blunt instrument will be inserted below that connective band, and, with gentle traction in the coronal direction, this muscular insertion should be detached freeing the lingual flap from the mylohyoid.

PROCEDURE

periosteal releasing incision

Full-thickness crestal incision will be made over the edentulous ridge followed by one full-thickness vertical incision on the buccal side and a full thickness flap will be raised. Xenograft and Ti-mesh will be used to augment the defective site then incremental incisions of 1-3 mm into the periosteum and submucosa will be used to advance the muco-periosteal flap. The flap will then be sutured with interrupted sutures.
