Thirty‐six completely edentulous patients were enrolled for a 5‐year prospective study testing the treatment outcome between splinted and unsplinted implants retaining a mandibular hinging overdenture. The patients were randomized into 3 groups of equal size depending on the attachment system used such as: magnets, ball attachments or bars (reference group). Only 1 implant out of the 72 had failed at the abutment stage. Not a single implant failed during the 5‐year loading period. The accumulation of plaque was significantly higher for the Magnet than for the Ball group. Bleeding on probing, as well as marginal bone level, attachment level and Periotestg values did not statistically differ among the groups, neither at year 1 nor at year 5. However, the Periotestm values were significantly lower at year 5 compared to year 1 for all groups, which indicates a higher rigidity at the bone‐implant interface. No correlation was found between bleeding on probing and marginal bone loss. We conclude that the connection state of 2 implants retaining a hinging overdenture did not influence the peri‐implant outcome.
