Osseodensification is a method of biomechanical bone preparation where specially designed burs increase density of bone as they expand an osteotomy. These osseodensifying burs combine advantages of osteotome bone preservation with the standard traditional drilling burs speed and tactile control. The investigators compared ridge splitting followed by osseodensification versus osseodensification in terms of buccolingual ridge expansion both clinically and radiographically.

Sixteen patients will be randomly allocated into two groups. Ridge splitting followed by osseodensification will be performed with simultaneous implant placement in group I.

Osseodensification will be performed with simultaneous implant placement in group II.

Alveolar ridge width and Implant stability will be assessed clinically. Alveolar ridge width and bone density will be assessed radiographically.

Inclusion Criteria:

• Patients suffering from missing single or multiple maxillay anterior and /or premolar with at least 8 mm alveolar ridge height, with 4-6mm alveolar buccolingual (BL) ridge width.
• Patients should be systemically healthy.
• Patients available during follow up periods.

Exclusion Criteria:

• Pregnant females.
• Smokers.
• Poor oral hygiene.
• Vulnerable patients
