Abstract

The primary aim of this study was to evaluate the efficacy of alveolar ridge preservation (ARP) ther- apy compared with unassisted socket healing (USH) in attenuating interproximal soft tissue atrophy. Adult patients who underwent maxillary single-tooth extraction with or without ARP therapy were included. Surface scans were obtained and CBCT was performed to digitally assess interproximal soft tissue height changes and measure facial bone thickness (FBT), respectively. Logistic regres- sion models were conducted to investigate the individual effect of demographic and clinical vari- ables. Ninety-six subjects (USH = 49; ARP = 47) constituted the study population. Linear soft tissue assessments revealed a significant reduction of the interproximal soft tissue over time within and between groups (P < .0001). ARP therapy significantly attenuated interproximal soft tissue height re- duction compared to USH: -2.0 ± 0.9 mm mesially for USH vs -1.0 ± 0.5 mm mesially for ARP; -1.9 ± 0.7 mm distally for USH vs -1.1 ± 0.5 mm distally for ARP (P < .0001). Thin (≤ 1 mm) facial bone thick- ness (FBT) upon extraction was associated with greater interproximal soft tissue atrophy compared to thick FBT (> 1 mm), independent of the treatment received (P < .0001). Nevertheless, ARP therapy resulted in better preservation of interproximal soft tissue height, especially in thin bone phenotype, by a factor of 2 for the mesial site (+1.3 mm) and by a factor of 1.6 for the distal site (+0.9 mm). This study demonstrated that ARP therapy largely attenuates interproximal soft tissue dimensional re- duction after maxillary single-tooth extraction compared to USH.

无辅助牙槽愈合与牙槽嵴保留疗法后近端软组织间高度的变化
本研究的主要目的是评估牙槽嵴保留(ARP)疗法与无助牙槽窝愈合(USH)疗法在减轻近端软组织萎缩方面的疗效。本研究纳入了接受或未接受 ARP 治疗的上颌单牙拔除术的成年受试者。通过表面扫描和锥形束计算机断层扫描分别对近端软组织间高度变化和面部骨厚度(FBT)进行数字化评估。采用逻辑回归模型研究人口统计学和临床变量对个体的影响。研究对象包括 96 名受试者(USH=49; ARP=47)。线性软组织评估显示,在组内和组间(P1mm),随着时间的推移,近端间软组织明显缩小,与所接受的治疗无关(P

期刊介绍: The International Journal of Periodontics & Restorative Dentistry will publish manuscripts concerned with all aspects of clinical periodontology, restorative dentistry, and implantology. This includes pertinent research as well as clinical methodology (their interdependence and relationship should be addressed where applicable); proceedings of relevant symposia or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published or submitted for publication elsewhere.
