Background: teeth loss in the anterior maxilla initiate residual ridge resorption, especially in the anterior region. The consequence of this resorption is a gradual medial or palatal shift of the crest of maxilla. This results in change in facial morphology as result of diminished maxillary lip support. This may also lead to compromised occlusal relationship of prosthetic teeth as they are positioned labially to the crest of alveolar ridge.

Aim: to compare the use of magnetic mallet and piezotome in atrophic anterior maxillary ridge expansion with simultaneous bone graft and implant placement.Materials and Methods: 20 patients with anterior atrophic maxilla will be included in the study. Patients will be divided into two groups, group A the bone expansion will be done by the magnetic mallet. Group B the bone expansion will be done by the piezotome , both groups will have bone graft and implant.

clinical evaluation will include intra operative and post operative evaluation, primary and secondary stability, operative time and time . Radiographic evaluation will include bone density and marginal bone loss around the tnalpmi

Inclusion Criteria:

• alveolar ridge width from 3-5 mm
• Patient with missing more than two anterior maxillary teeth
• Patient with good oral hygiene and acceptable inter-arch space[8-12mm] for the restoration
• D3 bone density

Exclusion Criteria:

• Heavy smoker, alcohol abuse, parafunctional habits.
• Patient with uncontrolled hypertension, uncontrolled diabetes, on radiation therapy
