Objective:
Evaluation of edentulous patients with severely resorbed mandibles simultaneously treated with bone out of the iliac crest and implants.
Design:
Prospective.
Material:
Thirty-one females between 42 and 61 years of age, were surgically treated and provided with a bar construction or attachments with an overdenture.
Methods:
Orthopantomograms were made after 3, 6, 12, 24 and 60 months. Bone resorption was measured mesial and distal from each implant.
Results:
Eight implants out of 78 inserted implants were lost. The average bone resorption was 0.6 mm after 3 months and 4.4 mm after 60 months. In some patients no bone resorption was found; in other patients the augmented bone was completely lost.
Conclusion:
The described surgical treatment did not give reliable results.
