Hydroxylapatite is commonly used for augmentation of the atrophic alveolar ridge. A new surgical technique is described for HA-augmentation and simultaneous vestibuloplasty on the severely atrophic jaw. The open surgical technique includes a lingually based mucoperiostal flap, the implantation of Hydroxylapatite particles in a vicryl mesh and the use of a positioning splint. First results show a sufficient depth of the vestibular sulcus and only few complications (circumscripted mucosal erosions). No lateral or lingual dislocation of the implanted HA-particles and no permanent mental nerve anaesthesia were observed. The prosthodontic results show increased stability and retention of the dentures following the one stage surgery.
羟基磷灰石常用于萎缩性牙槽嵴的增高。本文描述了一种新的手术技术，用于在严重萎缩的颌骨上进行羟基磷灰石增高术及同期前庭成形术。开放式手术技术包括舌侧带蒂黏膜骨膜瓣、在可吸收聚乙醇酸网片中植入羟基磷灰石颗粒以及使用定位夹板。初步结果显示前庭沟深度足够，且仅有少量并发症（局限性黏膜糜烂）。未观察到植入的羟基磷灰石颗粒向外侧或舌侧移位，也未出现永久性颏神经麻醉。修复结果显示，一期手术后义齿的稳定性和固位力有所提高。
