Enrollment: 7 estimated patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Partially edentulous patients in the mandibular posterior region.
• Patients with healthy systemic condition.
• Insufficient ridge width (< 5mm).
• Presence of proper inter-arch space for placement of the implant prosthetic part.
• Adequate soft tissue biotype (≥ 2 mm).

Exclusion criteria

• Patients with systemic conditions that may interfere with the results of the study.
• Patients with local pathological defects related to the area of interest.
• Unmotivated, uncooperative patients with poor oral hygiene.
• Patients with habits that may jeopardize the implant longevity and affect the results of the study such as smoking, alcoholism or para-functional habits.

The Coronally Advanced Lingual Flap

Experimental group

Description:

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

Active Comparator group

Description:

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
