Abstract

Background: To date, the clinical evidence regarding the effectiveness of alveolar ridge preservation (ARP) in restricting alveolar bone height and width change after extraction at periodontally compromised molar extraction sockets still remains controversial. This retrospective cohort study aims to evaluate the effect of ARP in molars extracted for periodontal reasons.

Methods: Retrospective data were collected from patient electronic records from January 2019 to December 2023. Patients with Stage III/IV periodontitis who underwent extraction of molars for periodontal reasons were screened for eligibility. The outcomes included the horizontal and vertical dimensions of alveolar bone. The need for additional augmentation procedure during implantation was also evaluated. A linear regression model was used to adjust for known confounders.

Results: A total of 80 sockets were included in this study, of which 27 sockets received ARP therapy after extraction while 53 sockets experienced natural healing (NH). ARP resulted in significantly less bone height change in the periodontally compromised molar sites compared to the NH group (p < 0.001). In sockets displaying a height disparity of >2 mm between the buccal and palatal/lingual walls, the ARP group exhibited advantageous outcomes in terms of ridge width change, surpassing the NH group (p = 0.004). Moreover, the percentage for additional augmentation was significantly reduced in the ARP compared to the NH group (p = 0.006). Age, sex, smoking, jaw, location, and buccal wall thickness did not show any significant effect on bone height change.

Conclusion: ARP had benefits on limiting ridge resorption subsequent to molar extraction for periodontal reasons.

牙周受损的臼齿拔牙窝的牙槽嵴保留效果:回顾性队列研究
背景:迄今为止,关于牙槽嵴保留(ARP)在牙周受损的磨牙拔牙窝拔牙后限制牙槽骨高度和宽度变化的有效性的临床证据仍然存在争议。这项回顾性队列研究旨在评估因牙周原因拔除的磨牙的牙槽嵴保留效果:从 2019 年 1 月至 2023 年 12 月的患者电子记录中收集回顾性数据。筛选出因牙周原因拔除磨牙的 III/IV 期牙周炎患者。研究结果包括牙槽骨的水平和垂直尺寸。此外,还评估了在种植过程中是否需要进行额外的增量手术。采用线性回归模型对已知的混杂因素进行调整:本研究共纳入了 80 个基台,其中 27 个基台在拔牙后接受了 ARP 治疗,53 个基台经历了自然愈合(NH)。与自然愈合组相比,ARP 使牙周受损的磨牙部位的骨高度变化明显较小(P = 2 mm),ARP 组在牙脊宽度变化方面表现出优势,超过了自然愈合组(P = 0.004)。此外,与 NH 组相比,ARP 组的额外增量比例明显降低(p = 0.006)。年龄、性别、吸烟、颌骨、位置和颊壁厚度对骨高度变化没有明显影响:结论:ARP对限制因牙周原因拔除臼齿后的牙脊吸收有好处。
