The purpose of this study was to report the clinical and radiographical outcomes of using autogenous cortical bone plates combined with sticky allogenic bone graft for augmenting maxillary anterior atrophic combined horizontal and vertical ridge defects with simultaneous versus staged implant placement.
Sufficient alveolar ridge is a prerequisite for successful implant stability, atrophic ridges defects make the placement of regular implants challenging. A variety of materials and surgical techniques are available for bone augmentation procedures prior implant placement. The present study evaluated the effect of sticky allogenic bone graft for the horizontal and vertical ridge augmentation with simultaneous implant placement using autogenous cortical bone plates in maxillary anterior atrophic ridge defects. Forty-two patients, with severe maxillary anterior horizontal and vertical atrophic ridge deficiencies were randomly assigned to two groups: staged approach group and simultaneous implant placement group. The two groups were grafted using bone plated buccally and palatally and the defect between plates was grafted by sticky allogenic bone graft. Radiographic examination was performed immediately before bone grafting procedure and at 6, 12 months postoperatively, to evaluate the change of bone width and height.

Stability Quotient of Implants (SQI)
The implant stability was recorded using Osstell TM. Following implant insertion, SQI readings were taken immediately, then again after six and twelve months.
Time frame: 12-month.
Horizontal bone dimensions (HBDs)
The HBD alterations were assessed by measuring horizontal spacing between the external edges of labial and palatal bony plates at a level 2mm apical of the fixture platform.
Time frame: 12-month.
Peri-implant Bone Density (PBD)
For consistent measurement of the PBD, 1-mm-diameter Region of interest (RI) was selected and traced 1.2 mm distant from the fixture on the cross-sectional slices followed by counting the threshold pixels inside the RI.
Time frame: 12-month.
