A technique is described using a subperiosteal tissue expander and particulate hydroxylapatite for reconstruction of the class IV edentulous mandibular alveolar ridge. The expander is placed under direct visualization via an extraoral approach so that it can be precisely positioned with relation to the inferior alveolar nerve. A fibrous capsule, having ideal ridge structure forms around the expander, and hydroxylapatite can be injected into this capsule from the intraoral route. The rationale for this technique and its advantages are discussed. It has been used in 17 patients with excellent results.
描述了一种使用骨膜下组织扩张器和颗粒状羟基磷灰石重建IV类无牙下颌牙槽嵴的技术。通过口外入路在直视下放置扩张器，以便能够相对于下牙槽神经精确地定位。在扩张器周围形成具有理想嵴结构的纤维囊，并且可以从口内途径将羟基磷灰石注入该囊中。讨论了该技术的原理及其优点。它已用于17例患者，效果极佳。
