1Division of Oral and Maxillofacial Surgery, Louisiana State University Medical Center, Shreveport.
Purpose:
To evaluate the results of hydroxylapatite augmentation of the mandible followed by placement of the mandibular staple.
Patients And Methods:
Sixty patients 5 or more years postsurgery were evaluated. Patients were followed yearly with clinical and radiographic examinations.
Results:
The decrease in augmentation height was 2.8 mm (33%) after the first year and only minimal in the following years. The following problems were seen: hyperplastic tissue around posts (eight patients), small dehiscences were seen in the saddle area after 2 years (11 patients), large dehiscences with significant hydroxylapatite loss in five patients. One patient needed a secondary augmentation.
Conclusion:
Prosthetic stabilization and function were excellent throughout the study period and there was a uniformly high degree of patient satisfaction.
