  3. Residual alveolar ridges covered with healthy firm mucosa. 5. All included patients will have sufficient available length and width of mandibular bone to accommodate conventional implant. (At least 5 mm buccolingual width and 12 mm vertical height of bone.

Exclusion criteria

• Patients with chronic systemic diseases that affect bone metabolism
• Uncontrolled diabetic patients
• Patients with TMJ dysfunction
• Smokers
