- Efficacy of I. Urban and F. Khoury techniques in guided bone regeneration: a systematic reviewPublication . Pasqualini, Erica; Castro, FilipeBackground: Guided bone regeneration (GBR) is one of the most important means of implant rehabilitation in cases of massive bone atrophy. Among the most tried and tested procedures, Khoury's Shell Technique and Urban's Sausage Technique differ in their methodology towards clot stability and grafting material. Objective: This systematic review aims to contrast the clinical efficacy and predictability of the two treatments in horizontal and vertical defect treatment, based on the most current scientific evidence. Methodology: The electronic databases searched were five in total (PubMed, Cochrane Library, Embase, B-On, ScienceDirect) and complemented with manual search. Clinical studies from the last five years, English language, conducted on human subjects, follow-up of a minimum of six months and with specific mention of utilization of Khoury or Urban technique included. The method quality in the studies was assessed using the JBI Critical Appraisal Tool. Twelve studies were included in the qualitative synthesis. Results: 13 articles were found that constitute this work. According to the findings, both methods allow clinically significant average bone gain, with a trend towards improved results in the pure mode methods compared with the variants. The Shell Technique was also found to be very effective for complex threedimensional defects with greater long-term stability, while the Sausage Technique was found to be universally effective in horizontal defects due to ease of surgery and the use of resorbable membranes. Conclusion: Both the techniques are safe methods in GBR with specific indications depending on defect anatomy and handling of soft tissues. Higher case series randomized clinical trials should be conducted in order to set standardized and predictable protocols.
