About

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.

Full description

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.

42 participants in 2 patient groups

Staged implant placement approach

Experimental group

Description:

the bone defect was grafted using bone plates buccally and palatally and the defect between plates was grafted by sticky allogenic bone graft. 6 months later the implant was placed in the grafted site.

Treatment:

Procedure: implant placement 6 months after ridge augmentation

Simultaneous implant placement approach

Experimental group

Description:

the bone defect was grafted using bone plates buccally and palatally and the defect between plates was grafted by sticky allogenic bone graft combined with simultaneous implant placement.

Treatment:

Procedure: implant placement Simultaneously with ridge augmentation
