Abstract

Background: Severe pneumatization of maxillary sinus with only 1-3mm of residual alveolar ridge usually requires a two stage surgical procedure: for sinus lifting and grafting followed by another entailing implant placement.

Purpose: The aim of this study is to assess the survival of dental implants placed in severely resorbed residual bone heights of 1-3mm; moreover, the implants are used to fix autogenous or allogenic bone blocks posterior maxilla in. a single stage surgery.

Materials and Methods: Six cases with severe posterior maxillary alveolar ridge resorption (1-3mm residual bone height present) were included in this trial. The patients received a total of 12 implants that were placed simultaneously with either: autogenous symphyseal cortico-cancellous bone rings (Control Group) or allogenic cortico-cancellous bone blocks; in which the implants were used as the fixation device to fix the graft in position.

Results: Upon early exposure of implants after 4 months only one implant failed to osseointegrate in the study group compared to four implants in the control group. Moreover, allogenic blocks with perforated sinus membrane, survived contrary to autogenous blocks.

Conclusion: Within the limitations of this clinical trial, bone blocks fixed with dental implants in severely atrophied posterior maxillae appear to be a technique with potential, yet, more latency period prior to loading is advisable.
