ABSTRACT
Abstract: This study aimed to compare the use of connective tissue grafts (CTG) and platelet-rich fibrin (PRF) associated with the tunnel technique (TT) for the treatment of multiple gingival recessions (GR). Fourteen patients with multiple bilateral GR [type 1 recession (RT 1)] in the maxillary incisors, canines, and/or premolars were included. The TT was performed on both sides (split-mouth model); CTG (36 GR) was used on one side, and on the other, PRF (36 GR) was used. Clinical parameters, including recession depth (RD), probing depth, clinical attachment level (CAL), and keratinized gingiva thickness/width (GT/KTW), were obtained at baseline and after 1, 3, 6, and 16 months. Lower RD (0.81 ± 0.68 vs. 1.23 ± 0.71 mm) and CAL (2.54 ± 0.63 vs. 2.73 ± 0.82 mm) were observed for CTG compared to PRF after 16 months. Higher GT was obtained for CTG compared to PRF after 3 (1.81 ± 0.56 vs 1.43 ± 0.47 mm) and 6 months (1.67 ± 0.61 vs. 1.38 ± 0.55 mm, p < 0.05). The recession coverage (RC) was higher for CTG (55.42% ± 37.14) in comparison to PRF (29.53% ± 34.08) after 16 months (p < 0.05). Similarly, CTG presented a more complete coverage of the recession (15; 41.66%) than PRF (9; 24.32%). There were no significant differences between the groups in terms of surgery time, postoperative pain, or healing patterns. Greater esthetic satisfaction was obtained with CTG. It was concluded that CTG combined with TT showed clinical and esthetic results superior to those of PRF in multiple GR treatments.
ABSTRACT
Introdução; O objetivo do tratamento odontológico é a manutenção da dentição natural com saúde e funçãodurante a vida do paciente. Este trabalho discute a possibilidade da utilização de transplantes dentaisautógenos como opção de reabilitação oral, através da apresentação de um caso. Método: O procedimentode transplante dental envolve a extração do dente doador, preparo do alvéolo receptor, posicionamento dodente transplantado, sutura e contenção temporária. Resultados e conclusões: Os resultados obtidos confirmama possibilidade de sucesso estético e funcional com os transplantes dentais autógenos
Introduction: The goal of dental treatment is to maintenance of the natural dentition health and functionduring to patient?s lifetime. This paper discusses the possibility of autogenous dental transplantations astreatment option and reports a case. Methods: The transplantation procedure involves extraction of the donortooth, preparation of recipient socket, positioning of donor tooth, suturing, and temporary splinting.Results and conclusion: The results confirm the possibility of a successful esthetic and functional treatmentwith autogenous teeth transplantation
