Title Dental Implants Placed Following Grafting in Areas with Severe Bone Resorption Can Be Successful
Clinical Question For a patient with severe ridge resorption needing an implant, would guided bone regeneration (GBR) allow for a high likelihood of implant success and survival?
Clinical Bottom Line For patients with bone dimensions insufficient for placement of a dental implant, guided bone regeneration is a valuable approach to allow placement of implants that have levels of success approaching that of standard (nonaugmented) implant placement.

#1) 22542079Clementini/20128 Studies-147 patientsSystematic review of randomized trials
Key resultsThe survival and success rates for implants placed following guided bone regeneration in severely resorbed alveolar ridges approached that of conventional implant placement; however, these rates did show high levels of variability. The implant survival rate ranged from 93.75% to 100%, with success rates reported from 61.5% to 100%. This is based on 8 studies evaluating 147 patients.

Comments on
The Evidence
Validity: The systemic review identified only a limited number of studies (8) with sufficient information reported to allow inclusion in the review. Seven of the eight studies were found to have a high to moderate risk of bias. Perspective: Based on this systematic review implant therapy represents a reasonable approach to care following successful ridge augmentation. This review did not specifically address the success of the guided bone regeneration procedure itself for severely atrophic ridges. This issue represents a separate level of risk that would need to be considered prior to selecting this treatment option.
Applicability This information can benefit a practitioner when treatment planning for a patient in need of implants and whose available bone is compromised by severe ridge resorption.

I conducted a Pubmed search on this topic in Sep 2022 and found a more recent publication PubMed ID: 28916205 that further strengthens the conclusion of this CAT
