Study Description
Brief Summary:
The purpose of this split-mouth clinical study is to evaluate the clinical, radiographic and histological outcomes of lateral window sinus augmentation with a bovine xenograft or a CPS putty bone substitute in posterior maxillary sites and the survival of implants placed in these sites following healing.

Outcome Measures

Primary Outcome Measures :
  1. Percentage of new bone growth in the maxillary sinus [ Time Frame: 7 months(plus minus 1 month) ]
    Difference between the percentage of new bone growth between the two groups as determined by histomorphometric analysis of bone cores retrieved during implant placement surgery.


Secondary Outcome Measures :
  1. Gain in vertical bone height [ Time Frame: 6 months (plus or minus 1month) ]
    Patients will be seen for radiographic evaluation post-sinus surgery. A cone beam computed tomography (CBCT) will be obtained and a blinded investigator will evaluate the vertical bone height at the sites.

  2. Radiographic bone density [ Time Frame: 6 months (plus or minus 1 month) ]
    Patients will be seen for radiographic evaluation. A cone beam computed tomography(CBCT) will be obtained and a blinded investigator will evaluate the volumetric grey values at each site as an index of bone quality.

  3. Primary implant stability [ Time Frame: 7 months (plus or minus 1 month) ]
    Primary stability of implants placed in the augmented sinuses will be evaluated as a clinical index of bone density.

  4. Marginal bone level maintenance [ Time Frame: 12 months(plus or minus 1 month) ]
    Intraoral radiographs, using a paralleling technique, with customized film holders will be obtained at baseline (time of abutment connection) and at the 12-month follow-up visit and evaluated by an independent investigator to assess marginal bone levels around the implant platform. The measurements will be performed mesially and distally of each implant.


Other Outcome Measures:
  1. Implant success [ Time Frame: 2nd stage, 6&12 months post-loading ]
    Patients will be evaluated for clinical symptoms and implant success using predetermined criteria.
