Effect of socket preservation therapies following tooth extraction in non-molar regions in humans: a systematic review

Abstract

Data concerning socket preservation therapies in humans are scarce, which does not allow any firm conclusions. Socket preservation may aid in reducing the bone dimensional changes following tooth extraction. However, they do not prevent bone resorption because, depending on the technique, on the basis of the included papers one may still expect a loss in width and in height.

Volumetric, Radiographic, and Histologic Analyses of Demineralized Dentin Matrix Combined with Recombinant Human Bone Morphogenetic Protein-2 for Ridge Preservation: A Prospective Randomized Controlled Trial in Comparison with Xenograft

“…Many studies on ridge preservation have documented the structural changes that occur around the alveolar ridge following ridge preservation [13,[33][34][35]. It is well-known that ridge preservation can limit and delay alveolar bone alteration [36,37]. Not all studies have reported beneficial effects from reducing alveolar ridge atrophy [36,38] which implies that ridge atrophy occurs in almost all the extraction sockets regardless of ridge preservation.…”

Not all studies have reported beneficial effects from reducing alveolar ridge atrophy [36,38] which implies that ridge atrophy occurs in almost all the extraction sockets regardless of ridge preservation. In this study, we reported negative postextraction remodeling changes (approximately 80% of original soft tissue volume) in all three groups after tooth extraction accompanied with ridge preservation (p < 0.05).…”

Ridge Alterations Post-extraction in the Esthetic Zone

“…Even thick-wall phenotypes exhibited bone loss of more than 1 mm, which could affect esthetics negatively. Efforts have been made to prevent these dimensional changes following tooth extraction, but neither immediate implant placement nor ridge preservation techniques were able to maintain the facial osseous architecture Ten Heggeler et al, 2011).…”

Clinical use of the resorbable bioscaffold poly lactic co-glycolic acid (PLGA) in post-extraction socket for maintaining the alveolar height: A prospective study

“…5 Although the bone resorption continues over time after tooth extraction, during the first month, the most statistically significant loss of alveolar dimension occurs. 6 Alveolar ridge resorption can create a clinical problem in two different ways: one, for the fabrication of conventional or implant-supported prostheses, an esthetic problem is created and second, it can make dental implants placement very difficult or sometimes even impossible. Therefore, following tooth extraction preservation of alveolar bone dimensions is always desirable.…”
