MDI survival, marginal bone level, peri\u2010implant health, technical complications, and oral health related quality of life (OHIP) and respective changes over time are reported.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>Subjects aged 50\u2009years or older, in need of improvement of maxillary denture retention, were included. The MDIs were 2.4\u2009mm diameter one\u2010piece tapered implants, Class 4 pure Titanium, and lengths 10 or 11.5\u2009mm. Under local anesthesia, 5\u20136 MDIs were placed in atrophic maxillae with a free\u2010handed flapless approach. One week postoperative the denture was adapted with a retentive soft reliner. The final prosthetic connection was established after 6\u2009months with a metal\u2010reinforced horse\u2010shoe denture. Clinical outcome after 5\u2009years was assessed with probing pocket depts (PPD), bleeding on probing (BoP), and additional cone beam computed tomography (CBCT) MDI bone level measurements were performed. Oral Health\u2010Related Quality of Life (OHRQoL) investigated with OHIP\u201014 was assessed preoperative, during provisional loading, and after final prosthetic connection up to 5\u2009years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Initially, 31 patients (14 females and 17 males) with mean age 62.30 underwent treatment. In the provisional loading interval, 16 patients encountered 32\/185 MDIs failures, resulting in a failure of 17.3%; 170 MDIs were functionally loaded in 29 patients. Additionally, 14 implants were lost in three patients, all of whom had had already previous failures.<\/jats:p><jats:p>Reimplantation of 17 MDIs were performed during the provisional loading and 2 MDI after functional loading. After 5\u2009years, the absolute implant failure rate was 46\/204 (22.5%), corresponding to a cumulative failure rate of 23.2%. Prosthetic failure was observed in four patients due to implant loss and in two patients related to excessive one\u2010piece implant ball attachment wear, making the 5\u2010years prosthetic success 80.0%.<\/jats:p><jats:p>The mean PPD and absence\/presence of BoP for 149 implants at 5\u2009years was 4.3 and 0.2\u2009mm, respectively. Average mesial\u2010distal\u2010vestibular\u2010palatal bone loss in the interval 2\u20135\u2009years was 0.08\u2009mm. No statistically significant difference in marginal MDI bone loss between male or female (<jats:italic>p<\/jats:italic>\u2009=\u20090.835), smoking and nonsmoking (<jats:italic>p<\/jats:italic>\u2009=\u20090.666) was observed. The five\u2010years total measured CBCT interdental bone level (mesial and distal) correlates with the 5\u2010years PPD (Pearson 0.434; <jats:italic>p<\/jats:italic>\u2009=\u20090.01). After 5\u2009years, OHRQoL with the treatment procedure was assessed in 27\/31 participants. Decreasing mean total OHIP\u201014 scores with improved OHRQoL, was observed in 27\/31 participants, with values of 21.3 at baseline to 15.6 at the time of provisional loading which significantly (<jats:italic>p<\/jats:italic>\u2009=\u20090.006) decrease to 7.3 at the final prosthetic connection. The next 3\u20135\u2009years further decrease was observed with 6.5 and 4.96, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Maxillary MDIs for overdentures are an accessible and acceptable treatment option. Although after 5\u2009years between one fifth and one fourth of the MDIs were lost, prosthetic success remains 80.0% and high OHRQoL could be
