ABSTRACT
BACKGROUND: Autogenous tooth transplantation refers to a surgical procedure involving the relocation of a tooth within the same individual. Incorporating platelet-rich fibrin (PRF) in this procedure holds the potential to improve healing, accelerate recovery, and optimize treatment outcomes. METHODS: In this article, the authors illustrate a PRF-based approach for autogenous tooth transplantation through two case scenarios. These cases outline the surgical steps of tooth transplantation and demonstrate the potential role of PRF in enhancing soft tissue healing. Furthermore, the article provides insights from a long-term follow-up spanning over 7 years. RESULTS: Tooth transplantation in young adults is promising but depends on factors such as root development stage and donor tooth size matching. Including PRF may improve healing, at least in the short term, due to its rich concentration of growth factors and cytokines, promoting effective tissue regeneration. CONCLUSIONS: Autogenous tooth transplantation has shown to be a viable treatment option for replacing the missing dentition. Adding PRF to the autogenous tooth transplantation procedure may speed up and enhance the treatment outcome. While the favorable results of these cases might be partially attributed to the use of PRF, the contribution of PRF to the healing process of tooth transplant remains conjectural and requires validation through additional research. KEY POINTS/HIGHLIGHTS: Tooth autotransplantation can be performed in younger patients without requiring root canal treatment, while also potentially benefiting from the incorporation of platelet-rich fibrin (PRF).
ABSTRACT
OBJECTIVES: This study investigated the efficacy of Vestibular Incision Subperiosteal Tunnel Access (VISTA) compared to other methods for treating multiple adjacent gingival recessions (MAGRs) through a systematic review and meta-analysis. MATERIALS AND METHODS: A systematic literature search was performed through June 2023, to identify clinical trials investigating VISTA for root coverage on MAGRs. A meta-analysis with meta-regression model was employed on the primary outcomes of mean and complete root coverages (MRC, CRC), comparing VISTA with other techniques. Clinical efficacy of various graft materials was assessed. RESULTS: Fourteen studies were included, 8 of which met the criteria for quantitative assessment. The cumulative MRC (88.15% ± 20.79%) and CRC (67.85% ± 21.72%) of VISTA were significantly higher compared to the tunneling technique (SMD = 0.83 (95% CI [0.36, 1.30], p < 0.01). The baseline recession depth showed a negative correlation with CRC, whereas baseline keratinized gingiva width exhibited a positive correlation with this outcome. CONCLUSIONS: The VISTA technique, particularly with acellular dermal matrix (ADM) or connective tissue graft (CTG) materials, offers superior outcomes compared to the tunneling technique. The capacity of platelet-rich fibrin (PRF) to substitute for connective tissue graft (CTG) in VISTA-root coverage was noteworthy, provided there is adequate keratinized tissue width. CLINICAL RELEVANCE: VISTA in concert with acellular dermal matrix or CTG resulted in improved root coverage, surpassing the outcomes achieved through tunneling. PRF emerged as a viable alternative to CTG, when used in conjunction with VISTA, demonstrating comparable mean root coverage. This is particularly evident in situations where sufficient keratinized gingiva is available and when patient comfort is taken into consideration.
