Abstract

Objective: The purpose of this single-centre retrospective study was to determine the long-term outcomes of the BIA400 and Ponto Wide, in terms of implant stability, soft tissue reactions, skin thickening and implant loss.

Methods: Adults who had the BIA400 or Ponto Wide implanted between January 2013 and December 2023 and had at least two follow-up appointments were included, leading to a cohort of 93 BIA400 and 114 Ponto Wide implants.

Results: Significantly more soft tissue reactions with a Holgers Scale score of 1 or greater (p = 0.003), adverse soft tissue reactions of Holgers Scale score of 2 or greater (p = 0.018), skin thickening (p < 0.001) and skin thickening requiring treatment (p ≤ 0.001) occurred in the BIA400 group. No difference in implant stability was found. One BIA400 implant (1.1 per cent) and three Ponto Wide implants (2.7 per cent) were lost.

Conclusion: Both implants have excellent implant stability and similar implant survival rates. The Ponto Wide has favourable outcomes in terms of (adverse) soft tissue reaction and skin thickening (requiring treatment).
