To quantify the buccal bone thickness, area, and perimeter following guided bone regeneration (GBR) using stabilizing periosteal sutures. The loss in hard tissue volume may impair proper implant placement. GBR has been used to regenerate the lost alveolar ridge prior to or at the same time as dental implant placement. The most important factor for GBR success is graft stability. The periosteal mattress suture (PMS) stabilizing technique is an alternative to pins and screws to stabilize bone grafting material and has the advantage of not requiring the removal of the fixing devices.
A CBCT was acquired before and 6 months after surgery from six patients who underwent GBR with the PMS stabilizing technique. Images were analyzed for buccal bone thickness, area, and perimeter.
The mean change in buccal bone thickness was 3.42 mm (± 1.31 SD) and proved statistically significant (P = .005). The mean change in bone crest area also proved statistically significant (P = .001). No significant difference was found in bone perimeter (P = .12).
The PMS technique delivered optimal results without clinical complications. This study shows the potential of this technique as an alternative to pins or screws for graft stabilization in the esthetic zone.
定量分析使用稳定骨膜缝线进行引导骨再生（GBR）后颊侧骨的厚度、面积和周长。硬组织体积的损失可能会影响种植体的正确植入。GBR 已被用于在种植体植入前或同时再生牙槽嵴的缺失部分。GBR 成功的最重要因素是移植物的稳定性。骨膜褥式缝线（PMS）稳定技术是替代销钉和螺丝固定骨移植材料的一种方法，具有不需要移除固定装置的优点。
对 6 名接受 PMS 稳定技术 GBR 的患者在术前和术后 6 个月进行 CBCT 检查。对颊侧骨厚度、面积和周长进行图像分析。
颊侧骨厚度的平均变化为 3.42mm（±1.31SD），具有统计学意义（P=0.005）。骨嵴面积的平均变化也具有统计学意义（P=0.001）。骨周长无显著差异（P=0.12）。
PMS 技术无临床并发症，效果理想。本研究表明，该技术在美学区域作为替代销钉或螺丝固定移植物的一种方法具有潜力。
