Abstract

Abstract: Objective To systematically evaluate the efficacy of applying the tent technique (TT) in alveolar ridge augmentation. Methods The PubMed, Embase, Scopus, Cochrane Library, CNKI, Wanfang, and SinoMed databases were electronically searched from April 1, 2002 to October 10, 2022 to identify clinical trials that employed TT in alveolar ridge augmentation. Results A total of 9 studies were included, of which 7 referred to horizontal ridge augmentation and 2 referred to vertical ridge augmentation. Meta-analysis indicated that TT had similar performance in horizontal ridge augmentation [MD=0.89, 95% CI (-0.07, 1.85), P=0.07] and postoperative complications compared with guided bone regeneration (GBR) [RR=3.90, 95% CI (0.85, 17.96), P=0.08]. Furthermore, TT had significantly less bone resorption than GBR and Onlay graft [MD=-3.98, 95% CI (-6.32, -1.65), P=0.0008], which could obtain more vertical ridge augmentation than the latter [MD=1.09, 95% CI (0.38, 1.81), P=0.003]. In terms of implant placement rate, their performance was as expected. Conclusion TT, as an alternative technique for alveolar ridge augmentation, achieves similar or better bone incremental performance than GBR or Onlay graft.
