Summary

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

Conditions

• Alveolar Bone Loss

Interventions

Type	Name	Description
PROCEDURE	ridge expansion by magnetic mallet	Surgery will be performed under local anesthesia using articaine with 1:100,000 adrenaline, a full-thickness buccal and palatal flaps will be raised. After the flaps were reflected, the crestal incision will be performed into the bone to perform an intra-osseous groove with an n. 64 beaver blade attached to magnetic mallet, this groove will be continued apically down to 7-11mm. The implant site will be created by expanding the bone tissue both laterally against the preexisting walls and apically by using osteotome attached to magnetic mallet, in this way the buccal plate will be slowly dislocated in a facial direction.
PROCEDURE	ridge expansion by piezotome	Surgery will be performed under local anesthesia using articaine with 1:100,000 adrenaline, after exposing the ridge, a sagittal osteotomy of 1mm depth will be outlined in the cortical bone by using sharp piezoelectric insert no. OT2. After that the sagittal osteotomic cut will be deepened with a 0.25 mm diameter piezoelectric micro-saw no. OT12s toward apical direction, at depth equivalent to the planned implant length. When the bone cuts will be completed, the ridges will be separated in buccal/lingual direction using densah burs . Then implants will be placed within the confines of the newly created space .
