For both groups, under general anesthesia; a mucosal incision 3-5 mm crestal to the vestibule will be made in the anterior region similar to the genioplasty incision, followed by dissection over the orbicularis oris and mentalis muscle and incising down to bone using a scalpel blade #15c mounted on a Bard-Parker® surgical blade handle size 3, to expose the proposed implant site. The incision will be completed posteriorly after localization of the mental nerves. After bone exposure the implant will be installed in place and fixed with 2.0mm grade 5 titanium screws.
