Título: | One-Abutment One-Time Effect on Peri-Implant Marginal Bone: A Prospective, Controlled, Randomized, Double-Blind Study | Autor: | Moreira, Filipe Rocha, Salomão José Coelho Silva Caramelo, Francisco Tondela, João P. |
Palavras-chave: | one abutment one time; implant–abutment connection; marginal bone loss; repeated abutment disconnection | Data: | 27-Jul-2021 | Editora: | MDPI AG | Título da revista, periódico, livro ou evento: | Materials | Volume: | 14 | Número: | 15 | Resumo: | Objective: To evaluate the peri-implant hard tissue change at 6 and 12 months after implant placement between definitive abutment placed at the same time of implant surgery, never removing it, and healing abutment disconnected and reconnected three times until the placement of the final rehabilitation. Material and methods: Each partial edentulous patient could receive between 1 and 4 platform-switched implants in the posterior regions. If the implants had primary stability—implant stability quotient (ISQ) equal to or greater than 50, they were randomized to the test group with the abutment inserted at the same time of implant placement (DA) or to the control group, receiving a healing abutment (PA). At 6 and 12 months after surgery, data related with vertical bone level changes (primary outcome) and other clinical parameters (implant mobility, bleeding on probing, probing depth, plaque index) were assessed. Results: 53 implants were included in the trial and completed 12 months follow-up (overall survival rate: 100%). All implants achieved primary stability, with an average ISQ value of 80.9 on the day of surgery. From surgery to 6 months, the mean bone loss was 0.14 0.18 mm for the DA group and 0.23 0.29 mm for the PA group, without statistical significance difference. Between 6 and 12 months, the mean bone loss was 0.14 0.21 mm for the DA group and 0.21 0.27 mm for the PA group, also without statistical significance between the two groups. There were no statistically significant differences (p = 0.330) in total bone loss after 12 months between the control and the study groups. Conclusions: The one abutment one time protocol has at least an equivalent effect on the peri-implant bone level changes when compared with the use of healing abutments that are disconnected and reconnected at least three times. | URI: | https://hdl.handle.net/10316/105216 | ISSN: | 1996-1944 | DOI: | 10.3390/ma14154179 | Direitos: | openAccess |
