Arm && Interventions

Group	Intervention	Description
The Coronally Advanced Lingual Flap	The coronally advanced lingual flap	On the lingual side of mandible, a full-thickness muco-periosteal flap is elevated until reaching mylohyoid line. Using a blunt instrument, a connective tissue band is localized continuing with the epimysium of the mylohyoid muscle and is inserted into the inner part of the lingual flap . The blunt instrument is inserted below the connective band, and with gentle traction in the coronal direction, this muscular insertion was detached from the lingual flap. Using a "periodontal probe" the amount of advancement is measured.
Modified periosteal releasing Incision	Modified periosteal releasing Incision	A full-thickness muco-periosteal flap is reflected on the buccal side. Near the base of muco-periosteal flap, the periosteum is incised less than 0.5mm in depth, creating two segments, "coronal segment" and "apical segment," of the periosteal flap. The flap is pulled with a pair of periodontal forceps laterally. Subsequently, the "lateral stretching" of the coronal segment of the flap is performed by applying pressure using the blunt face of scalpel blade, or a blunt instrument, with sweeping motion. This motion helps stretching the flap over the submucosa, thereby permitting the flap to be mobile.Using a "periodontal probe" the amount of advancement is measured

Primary Outcome Measures

Name	Time	Method
Flap advancement	"10 minutes"	Flap advancement will be measured as a difference between the value before and after in millimeters using periodontal probe.

Secondary Outcome Measures

Name	Time	Method
Postoperative Pain	1 Week	Postoperative Pain will be recorded using Numerical Rating scale (NRS) The scores will be recorded postoperatively by the patient for the seven days of observation.
Postoperative membrane exposure	12 Weeks	Postoperative membrane exposure will be evaluated at 1, 2, 3, 4, 12 weeks using a periodontal probe in millimeters.
bone density	12 Weeks	bone density will before and after with cone beam computed tomography (CBCT)
postoperative swelling	"1 week"	postoperative swelling will be recorded using descriptive four point scale(Penarrocha et al.2006).The scores will be recorded postoperatively by the patient for the seven days of observation.
