Title Bone Quality and Quantity Should Be Considered Before Placing Dental Implants on Postmenopausal Women
Clinical Question In patients with dental implants, is there a higher failure rate when implants are placed on postmenopausal women compared to women that are pre-menopausal?
Clinical Bottom Line Bone quality and quantity need to be considered prior to placing dental implants on post menopausal women. This is based on a clinical study of pre-menopausal and postmenopausal women, in which there is significantly less bone mass density of the mandibular edentulous bone of post menopausal women.

(level of evidence)
#1) 22207877Munakata/201130 premenopausal women and 42 post menopausal women aged 30-70 with edentulous mandibular molar regions. Comparative Clinical Study
Key resultsThe bone mass density (BMD) and its correlation with trabecular bone width (TW) and cortical bone width (CW) were measured with computed tomography. The BMD (mg/ml) was significantly lower in the pre-menopausal women (222± 88, p<.005) compared to the post menopausal women (109 ±69). There was a negative correlation for BMD with TW for pre-menopausal women, however there was no correlation in postmenopausal women. For premenopausal women, BMD correlated negatively with TW (r = −0.592, p<0.001) and there was no correlation with CW( r=0.244, p=0.125). No correlations between BMD with TW (r=-0.47 and p=0.018) or CW (r=0.111, p=0.195) were observed for postmenopausal women.

Comments on
The Evidence
The bone mass density, cortical bone width and trabecular bone width were measured in both groups. The patient population did not include those with impaired bone metabolism or those that were using medication to change the bone metabolism. The study did not take into account other factors such as years after menopause, other regions of the alveolar bone, and systemic conditions There were no competing interest present. The actual failure/success rate were not tested in this study so no conclusions can be made.
Applicability This study is somewhat applicable to the clinical question. The study measured the bone quality and quantity in both groups; however, no dental implants were placed to test the results. The assumption that menopause would increase failure rate can be made, but there is no evidence to prove the theory.
