The present study describes 3 patients with chronic periodontitis and consequent vertical resorption of the alveolar ridge who were treated using implant-based restoration with guided bone regeneration (GBR).
After extraction of a periodontally compromised tooth, vertical bone augmentation using a K-incision was performed at the healed, low-level alveolar ridge.
The partial-split K-incision enabled soft tissue elongation without any change in buccal vestibular depth, and provided sufficient keratinized gingival tissue during GBR.
Within the limits of this study, the present case series demonstrated that the novel K-incision technique was effective for GBR and allowed normal implant-based restoration and maintenance of a healthy periodontal condition. However, further long-term follow-up and a large-scale randomized clinical investigation should be performed to evaluate the feasibility of this technique.
本研究描述了3例患有慢性牙周炎并伴有牙槽嵴垂直吸收的患者，他们接受了基于种植体的引导骨再生（GBR）修复治疗。
在拔除一颗牙周状况不佳的牙齿后，在愈合的低水平牙槽嵴处采用K形切口进行垂直骨增量。
部分劈开的K形切口可使软组织伸长，而颊侧前庭深度无任何变化，并在引导骨再生过程中提供足够的角化牙龈组织。
在本研究的范围内，本病例系列表明，新型K形切口技术对引导骨再生有效，并允许进行正常的基于种植体的修复以及维持健康的牙周状况。然而，应进行进一步的长期随访和大规模随机临床研究，以评估该技术的可行性。
