Volumetric changes in alveolar ridge preservation with a compromised buccal wall: a systematic review and meta-analysis

Abstract

Background Many studies have addressed socket preservation, though fewer publications considering buccal wall loss can be found, since the literature typically considers sockets with four walls. A systematic review was made on the influence of type II buccal bone defects, according to Elian’s Classification, in socket grafting materials upon volumetric changes in width and height. Material and Methods An electronic and manual literature search was conducted in accordance to PRISMA statement. The search strategy was restricted to randomized controlled trials (RCTs) and controlled clinical trials (CCTs) describing post-extraction sockets with loss of buccal wall in which alveolar ridge preservation (ARP) was carried out in the test group and spontaneous healing of the socket (SH) was considered in the control group. Results The search strategy yielded 7 studies. The meta-analysis showed an additional bone loss of 2.37 mm in width ( p > 0.001) and of 1.10 mm in height ( p > 0.001) in the absence of ARP. The reconstruction of the vestibular wall was not evaluated in any study. The results also showed moderate to great heterogeneity among the included studies in terms of the changes in width and height. Conclusions Despite the heterogeneity of the included studies, the results indicate a benefit of ARP versus SH. Further studies are needed to determine the volumetric changes that occur when performing ARP in the presence of a buccal bone wall defect. Key words: Alveolar ridge preservation, buccal wall defect, volumetric changes, bone loss, meta-analysis.

Histological and dimensional changes of the alveolar ridge following tooth extraction when using collagen matrix and collagen‐embedded xenogenic bone substitute: A randomized clinical trial

“…When performing ARP in severely compromised socket, raising partial 15 or full thickness flaps 16 will be needed, such a procedure might be considered as a ridge augmentation procedure, rather than ARP. A meta‐analysis of six studies with ARP in compromised buccal wall sites, reported a high degree of heterogeneity 17 . In the current study, we focused on sites with a‐traumatic extraction with minimal soft tissues manipulation.…”

“…A meta-analysis of six studies with ARP in compromised buccal wall sites, reported a high degree of heterogeneity. 17 In the current study, we focused on sites with atraumatic extraction with minimal soft tissues manipulation. CMXS served as a durable barrier between the grafted socket and the oral cavity for the initial 30 days healing period.…”

Effect of different platelet‐rich fibrin matrices for ridge preservation in multiple tooth extractions: A split‐mouth randomized controlled clinical trial

“…However, the extension of alveolar bone resorption may vary depending on tooth type as observed by Couso‐Queiruga et al (2021) with a higher radiological horizontal bone resorption in molar sites vs non‐molar sites (3.61 vs. 2.54 mm). An additional bone loss of 2.4 mm in width and of 1.1 mm in height has been reported in sites with compromised buccal bone wall (García‐González et al, 2020). Interestingly, these numbers only comprise single tooth extractions, making the additional ridge resorption in cases with multiple extractions less quantifiable.…”

Platelet-rich fibrin (PRF) membrane isolated and injectable-PRF-mixed particulate bovine bone graft in rattibiae non-critical defects healing

“…Different regenerative procedures have been proposed to neutralize alveolar resorption processes and preserve the bone for subsequent rehabilitation. Alveolar ridge preservation (ARP) using a combination of various surgical techniques and biomaterials is considered a valid therapeutic option that signi cantly reduces post-extraction ridge dimensional changes [7]. Speci cally, ARP procedures aim to minimize crestal resorption and maximize bone regeneration through the immediate placement of a biomaterial within the socket [5].…”
