The Effects of Alveolar Ridge Preservation: A Meta‐Analysis

Abstract

Resorption of the alveolar ridge cannot be totally stopped by ARP, while it still can be prevented compared with unassisted healing. No reliable predictions on the histological effects could be made due to limited data. Further on, no recommendation for a specific technique of ARP could be made. In conclusion, there is still need for ongoing research on the topic, even though the lower percentage of implant sites that needed additional augmentation in test sockets seemed to bring a patient benefit.

Alveolar ridge preservation using an open membrane approach for sockets with bone deficiency: A randomized controlled clinical trial

“…It should be noted that previous studies did not include a negative control (eg, a group with naturally healed sockets). In previous systematic reviews with meta‐analyses, the mean differences in horizontal ridge width and the vertical ridge height between the ARP‐received sockets and the naturally healed sockets were 1.31 to 1.89 mm and 0.74 to 2.07 mm, respectively, favoring ARP compared to natural healing . The present study confirms a statistically significantly decrease in horizontal shrinkage (approximate difference at HW1 between the test and the control group: 2.6 mm), but no significant changes in vertical shrinkage.…”

Prospective randomized controlled clinical trial to compare hard tissue changes following socket preservation using alloplasts, xenografts vs no grafting: Clinical and histological findings

“…Toloue utilized a calcium sulphate (CS) bone graft and reported somewhat greater horizontal bone loss (−1.33 mm) as compared to 0.5 mm in the present study, with comparable and minimal vertical bone loss. Willenbacher and co‐workers in a systematic review and meta‐analysis of socket preservation reported that the weighted mean differences between grafted and nongrafted sites were 1.31‐1.54 mm in the horizontal direction and 0.91‐1.12 mm in the vertical direction. In comparison, in the present study, the differences in the vertical direction were somewhat smaller (0.4 mm) and the differences in the horizontal direction were somewhat greater (1.0‐2.46 mm).…”

Efficacy of collagen matrix seal and collagen sponge on ridge preservation in combination with bone allograft: A randomized controlled clinical trial

“…occlusive membranes and/or bone grafts) (Araujo & Lindhe, ; Artzi, Tal, & Dayan, ; Barboza, Stutz, Ferreira, & Carvalho, ; Barone, Ricci, Tonelli, Santini, & Covani, ; Barone et al., ; Brownfield & Weltman, ; Darby, Chen, & De Poi, ; Engler‐Hamm, Cheung, Yen, Stark, & Griffin, ; Fickl, Zuhr, Wachtel, Stappert et al., ; Iasella et al., ; Lekovic et al., ; Mardas, Chadha, & Donos, ; Weng et al., ). These studies and systematic reviews (Esposito et al., ; Hammerle et al., ; Ten Heggeler et al., ; Vignoletti et al., ; Wang & Lang, ; Willenbacher, Al‐Nawas, Berres, Kammerer, & Schiegnitz, ) point to a significant reduction, but not complete elimination, in vertical and horizontal bone resorption compared to unassisted socket healing after ARP procedures. The present findings confirm that complete preservation of the alveolar ridge dimensions after tooth extraction is unlikely to be attainable even if ARP procedures are employed.…”
