The success of osseointegration depends in part on the state of the host bed. Concerns have therefore been raised about osteoporosis, a condition believed to be associated with a decrease in bone quality and quantity. However, the orthopedic literature indicates that osteoporotic fractures heal readily and that the level of bone mass and estimates of the parameters associated with bone remodeling present considerable overlap between patients with osteoporosis and control subjects. It also appears that osteoporosis, as diagnosed at one particular site of the skeleton, is not necessarily seen at another distant site. Although the prevalence of osteoporosis increases among the elderly and after menopause, the results of this study indicate that implant failure rate is not correlated with age and sex. A review of the literature and of results of a series of patients treated does not provide a compelling theoretical or practical basis to expect osteoporosis to be a risk factor for osseointegrated dental implants.
骨结合的成功部分取决于植入床的状态。因此，人们对骨质疏松症产生了担忧，这种病症被认为与骨质和骨量的减少有关。然而，骨科文献表明，骨质疏松性骨折愈合容易，而且骨质疏松症患者与对照组受试者之间，骨量水平以及与骨重塑相关参数的估计值存在相当大的重叠。似乎在骨骼某一特定部位诊断出的骨质疏松症，在另一遥远部位不一定会出现。尽管骨质疏松症在老年人和绝经后人群中的患病率会增加，但本研究结果表明，种植体失败率与年龄和性别无关。对文献以及一系列接受治疗患者的结果进行回顾，并未提供令人信服的理论或实践依据，来预期骨质疏松症会成为骨结合牙种植体的一个风险因素。
