In addition, four mandibular implants experienced fracture. The difference between the 4‐year survival rates of 94.3% for the maxilla and 95.7% for the mandible was not statistically significant (<italic>p </italic>=<italic> </italic>0.581). All original 144 overdentures remained functional. The prosthetic interventions were typically limited to repairs of acrylic base fractures (about one in five patients), changes of plastic O‐rings and relining procedures. The participants showed OHIP‐G14 scores (median = 2) that were comparable with those of patients with overdentures retained by conventional implants.</p> </sec> <sec id="ger12066-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Mini‐implant survival was similar to that of regular‐diameter implants. Although some prosthetic aftercare was necessary, none of the overdentures had to be replaced. Prospective studies comparing conventional and mini‐implants are warranted.</p> </sec> </abstract>
