Abstract

Socket preservation (SP) is a method aimed at reducing the post-extraction resorption of the alveolar crest and promoting bone deposition in the socket. It involves procedures such as atraumatic tooth extraction, guided regeneration with barrier membranes and bone substitutes, socket sealing, and immediate implant placement. This research aims to evaluate the influence of the combination of dense polytetrafluoroethylene (d-PTFE) membranes and platelet-rich plasma (PRP) on the vertical post-extraction resorption at the premolar and molar sites. Forty participants, aged 18-65 years, who needed extraction of a premolar or molar were enrolled and randomly assigned to an experimental group (SP with d-PTFE membrane and PRP) or a control group (spontaneous socket healing). The results demonstrated that SP with non-porous PTFE membranes and PRP reduced vertical bone resorption at the premolar and molar sites. Data analysis suggested that the buccal plate width influences the amount of its vertical resorption, but not as much as the management of the post-extraction socket (SP versus spontaneous socket healing). Further longitudinal randomized controlled trials are necessary to clarify which factors influence post-extraction ridge resorption and evaluate the success of different SP techniques.

摘要

牙槽窝保存（SP）是一种旨在减少拔牙后牙槽嵴吸收并促进牙槽窝内骨沉积的方法。它涉及诸如无创拔牙、使用屏障膜和骨替代物的引导性骨再生、牙槽窝封闭以及即刻种植体植入等操作。本研究旨在评估致密聚四氟乙烯（d-PTFE）膜与富血小板血浆（PRP）联合应用对前磨牙和磨牙部位拔牙后垂直吸收的影响。招募了40名年龄在18至65岁之间、需要拔除前磨牙或磨牙的参与者，并将他们随机分为实验组（使用d-PTFE膜和PRP的牙槽窝保存）或对照组（牙槽窝自然愈合）。结果表明，使用无孔PTFE膜和PRP的牙槽窝保存减少了前磨牙和磨牙部位的垂直骨吸收。数据分析表明，颊侧板宽度会影响其垂直吸收量，但不如拔牙后牙槽窝的处理方式（牙槽窝保存与牙槽窝自然愈合）影响大。有必要进行进一步的纵向随机对照试验，以明确哪些因素会影响拔牙后牙槽嵴吸收，并评估不同牙槽窝保存技术的成功率。
