Abstract

Introduction: It is not known so far performing Alveolar Ridge Preservation (ARP) in a freshly extracted socket with intact walls would improve clinical outcomes of implants placed in these sites. It is not known whether different biomaterials and techniques would affect the survival of dental implants.

Aim: The current systematic review is undertaken to assess the survival rate of dental implants placed in these sockets and to assess different socket graft materials as well as techniques of ridge preservation with regard to the survival of implants.

Material methods: Search for relevant articles was done in Medline (PubMed). No restrictions were imposed with respect to the year of publications. Only the studies which mentioned that they placed dental implants in an extraction socket with intact walls were included.

Results: With the initial search a total of 4,962 articles were obtained. Out of which 9 studies (4 randomized controlled trials, 3 case series, 1 prospective, 1 retrospective) were included. Of the included studies, 6 studies reported an implant survival rate (ISR) of 100%, two studies reported an ISR of 97.3% and one study reported an ISR of 95%. The need for further augmentation was significantly reduced if the socket underwent ARP at the time of extraction and this difference is statistically significant compared to naturally healed sites. After prosthetic loading of implants, these sites presented with minimal peri-implant marginal bone level changes.

Conclusions: To conclude, ISR in an ARP site with an intact socket is 95%-100% with a mean of 98.8%. It was found that there is no statistically significant difference in ISR whether it is an ARP site or a site that underwent a natural healing process. Performing ARP even sockets intact reduce the need for further augmentation thereby simplifying the technique of implant placement while saving the time for the clinician as well as the patient.
