| dc.description.abstract | Objectives:
Alveolar ridge preservation (ARP) procedures can limit bone changes following tooth extraction. However, the role of ARP in periodontally compromised socket lacks strong scientific evidence. The aim of this systematic review and meta analysis was to evaluate the outcomes of ARP following extraction of periodontally compromised teeth in comparison with extraction alone in terms of hard tissue changes, need for additional augmentation at the time of implant placement, and patient-reported outcomes.
Material and Methods:
Electronic databases were searched to identify randomized controlled trials (RCTs) that compared ARP in periodontally compromised sockets with spontaneous socket healing. The risk of bias was assessed using the Cochrane Collaboration's risk of bias tool.
Results:
Five studies with 134 extraction sockets in 126 participants were included. Of these, ARP was performed in 77 sites, while the remaining sites were intentionally left to heal without any ARP treatment. The follow-up time varied between 6 and 12 months. Overall meta-analysis showed significant differences in changes in ridge height (mean difference (MD) −0.95; 95% confidence interval (CI) −1.43 to −0.47; p = .0001) and bone volume (MD −38.70; 95% CI −52.17 to −25.24; P<.0001) in favor of ARP. The use of ARP following extraction of periodontally compromised tooth was also associated with significantly less need for additional bone grafting at the time of implant placement.
Conclusions:
Within the limitation of this review, ARP following extraction of periodontally compromised teeth may have short-term positive effects on alveolar ridge height and bone volume and minimize the need for additional augmentation procedures. However, the evidence is of very low to low certainty. | en_US |
