Objectives The superiority of mandibular two‐implant overdentures ( IOD s) over conventional complete dentures ( CD s) in terms of quality of life is still questioned. Furthermore, the stability and magnitude of the treatment effect over time remain uncertain. This follow‐up study aimed to determine the stability and magnitude of the effect of IOD s on oral health‐related quality of life ( OHRQoL ). Material and methods 172 participants (mean age 71 ± 4.5 years) randomly received CD s or IOD s, both opposed by conventional maxillary dentures. OHRQoL was measured using the O ral H ealth I mpact P rofile ( OHIP ‐20) at baseline, 1 and 2 years post‐treatment. Repeated measures ANOVA s were conducted to assess the effects of time and treatment on the total OHIP and its individual domain scores. Results A statistically significant improvement in OHRQoL was seen for both treatment groups ( P < 0.001). This improvement was maintained over the 2 year assessment. At both follow‐ups, participants wearing IOD s reported significantly better total OHIP scores than those wearing CD s ( P < 0.001), with a 1.5 times larger magnitude of effect. In the CD group, baseline OHIP scores influenced the post‐treatment scores ( P < 0.001). This effect was not found in the IOD group. Conclusions The effect of mandibular two‐ IOD s on OHRQoL is stable over a 2‐year period. The large magnitude of effect of this treatment supports its clinical significance.
