In recent years, considerable attention has been given to the interrelationship between the outbreak of a systemic process of reduction in the bone mass and the possibility of a significant resorption of the alveolar bone. The degree of alveolar bone loss increases with age, and this may be related, at least in part, to the systemic conditions that also encourage the development of osteoporosis. Although numerous studies have documented the possible role of osteoporosis as a deteriorating factor in both tooth loss and mandibular bone resorption, this article underlines how the morphostructural evolution of the edentulous mandible is primarily correlated to mechanical factors as a result of modifications to its function. We will also take into consideration the therapeutic advantages provided by prosthetic rehabilitation on osseointegrated implants, in terms of reinstatement of the loading conditions through patterns of propagation of mechanical forces that are similar to physiologic ones.
近年来,骨量系统性减少过程的爆发与牙槽骨显著吸收的可能性之间的相互关系受到了相当多的关注。牙槽骨丧失的程度随年龄增长而增加,这可能至少部分与同样促使骨质疏松发展的全身状况有关。尽管众多研究记录了骨质疏松作为牙齿脱落和下颌骨吸收恶化因素的可能作用,但本文强调,无牙下颌骨的形态结构演变主要与因功能改变而产生的机械因素相关。我们还将考虑骨结合种植体的修复性康复在通过类似于生理力的机械力传播模式恢复加载条件方面所提供的治疗优势。
