There is limited information on the need for bone augmentation in the context of delayed implant placement whether alveolar ridge preservation (ARP) is previously performed or not. The primary aim of this retrospective cohort study was to evaluate the efficacy of ARP therapy after tooth extraction compared with unassisted socket healing (USH) in reducing the need for ancillary bone augmentation before or at the time of implant placement.

牙槽嵴保留减少了种植体治疗中辅助骨增强的需要

无论之前是否进行了牙槽嵴保留 (ARP)，关于在延迟种植体植入的情况下是否需要骨增强的信息有限。这项回顾性队列研究的主要目的是评估拔牙后 ARP 治疗与无辅助牙槽愈合 (USH) 相比在减少种植体植入前或植入时辅助骨增强需要的效果。
