Abstract:
BACKGROUND:There is no design that can completely rule out the intermittent impact damage to implants, therefore, a new bal attachment-retained implant system is constantly updated and developed. OBJECTIVE:To evaluate the clinical effectiveness of an implant-supported mandibular overdenture retained with a bal attachment. METHODS: We searched the Cochrane Library, PubMed, Medline, EM-base, WanFang Data, CNKI, VIP and other databases by computer to colect randomized controled trials addressing the implant-supported mandibular overdenture retained with a bal attachment and other control methods for dentures. The time limit was from database creation to February 2014. Two researchers independently completed literature screening according to inclusion and exclusion criteria, data extraction and quality assessment. RevMan 5.1 software was used for meta-analysis. RESULTS AND CONCLUSION: There were 10 studies included in result analysis, including 7 from China and 3 from other countries. Analysis results showed that statistical heterogeneity was remarkable in included studies, and there was no significant difference in patient’s satisfaction, clinical and objective indicators, and complications, suggesting that this approach continues to be explored in clinic. The implant-supported bal attachment-retained mandibular overdenture is relatively expensive, which is identical with the current research progress that is in the exploration stage worldwide. Due to the limited quantity and quality of included studies, the conclusions of this systematic review only provide references for clinical practice and research. The implant-supported bal attachment-retained mandibular overdenture stil needs further exploration and improvement.
