Paper 2 investigated the changes in speech, satisfaction with speech and overall oral health and the Oral Health Related Quality of Life (OHRQoL) in edentulous patients during and after treatment with maxillary IODs. Twenty- one patients receiving an IOD participated in speech assessment. They were examined pre-operatively with their conventional denture (CD) with full palatal coverage, after connection of the implant-bar connected denture, without palatal coverage, and 3 years thereafter. The examination included assessment of articulation in speech, OHRQoL based on total OHIP-14, and satisfaction with overall oral health and speech (VAS). There was a reduction in mean number of articulation disorders from 1.00 at baseline to 0.55 at connection, although statistically insignificant (p = 0.059). Especially the /s/ sound is vulnerable. At 3 years follow-up, still 6/16 (37.5%) of the patients suffered from this speech problem. Overall satisfaction improved from 64.05/100 at baseline to 82.95/100 at connection (p:0.008) and remained unchanged with 81.69/100 after 3 years follow-up. Patients’ satisfaction with speech increased from 70.62/100 with CD to 82.63/100, 3 years follow-up (p:0.009). Total OHIP-14 decreased from 21.45/56 with CD to 8.00/56 (p<0.001) with IOD and 6.13/56 three years after connection (p:0.001). Significant improvement of all 7 domains in OHRQoL was observed with IOD compared to CD.

Summary and social relevance
Conclusion: Patients treated with maxillary IODs show improved OHRQoL 3 years after connection of the IOD compared to the CD. Even though patients reported improvement of satisfaction and OHRQoL, articulation disorders were still present, suggesting that patients should be informed about possible speech issues.
Paper 3 determined speech, oromyofunctional behavior, satisfaction with the treatment and the impact on quality of life of the horse-shoe overdenture retained by mini-implants (MDI) in the maxilla. This prospective multicenter cohort study included 32 patients for treatment. 5 to 6 implants were placed, atraumatically piercing the mucosa. Patients were evaluated three times during treatment (preoperatively with conventional prosthesis including full palatal coverage (CD), postoperatively with provisionally relined CD and with horse- shoe overdenture on MDI). The assessment included a phonetic evaluation, examination of oromyofunctional behavior, evaluation of the impact on quality of life (OHIP-14) and a rating of satisfaction with the treatment and speech on
