Simultaneous Implant Placement With Vertical and Horizontal Bone Augmentation

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Good general health at the time of surgery
  • At least 3 months of healing after tooth extraction
  • Horizontally and vertical compromised alveolar ridges

Exclusion criteria

  • Thick cortex in the labial/buccal with less cancellous bone inside;
  • Obvious undercut on the labial/buccal side
  • Uncontrolled periodontal conditions or other oral disorders;
  • history of radiotherapy in the head and neck region

Treatment and study plan

implant placement 6 months after ridge augmentation

Procedure

the deficient ridge was grafted first followed by implant placement after 6-monthes

implant placement Simultaneously with ridge augmentation

Procedure

the deficient ridge was grafted and followed by implant placement simultaneously

Primary outcomes

  1. Stability Quotient of Implants (SQI)

    Time frame: 12-month.

    The implant stability was recorded using Osstell TM. Following implant insertion, SQI readings were taken immediately, then again after six and twelve months.

  2. Horizontal bone dimensions (HBDs)

    Time frame: 12-month.

    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.

  3. Peri-implant Bone Density (PBD)

    Time frame: 12-month.

    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.
