The postmenopause is a state characterized by the estrogen deficiency that can lead to metabolic disorders of the bony weave, osteopenia and osteoporosis. Although a contraindication for implant placement in these patients does not exist, the predictability in the prognosis in the long term is not clear yet.
Objectives: The aim of this study was to evaluate the behavior of osseointegrated implants in postmenopausal patients.
Material and Methods: 24 postmenopausal female patients, who received 59 implants, 37 in the maxilla and 22 in the mandible (Group M) were selected. 23 premenopausal female patients, under the age of 50, who received 39 implants, 24 in the maxilla and 15 in the mandible, served as controls (Group C). Baseline Periotest values (PTV) were recorded at second stage surgery. The second measurement has been taken after 12 months of the placement of the prosthesis, and then at 24 and 36 months.
Results: Differences between both groups in the maxilla were observed for 2nd stage surgery as well as at 12, 24 and 36 months. Nevertheless, the differences between both groups in the mandible were not significant.
Conclusions: In the mandible, local bony quality has shown to be more important, and it was not influenced by the postmenopausal condition. However, in the maxilla this condition seems to aggravate the local bony condition, as regards the controls. Postmenopause can be considered a relative risk factor in the maxilla, and of no importance to the mandible.
