Three-year prospective clinical and radiographic longitudinal study

11. August 2021

The results presented in this study demonstrate the high success and predictability of two-stage BioniQ dental implants with a structured, bioactive, moderately rough BIO (MR) fixture neck surface.

After three years in function, the mean marginal bone loss was 0.36 ± 0.57 mm and 0.13 ± 0.42 mm, taking implant and prosthesis placement baselines, respectively.

Direct contact of connective tissue with the moderately rough BIO (MR) fixture neck surface during supracrestal and equicrestal insertion prevents marginal bone resorption during biologic width restoration in patients with thin and thick gingival biotype.

The positive correlation between biologic width violations and marginal bone resorption was documented.
