 Abstract
Background: Large proportions of patients are edentulous and wear removable dentures leading to reduced functional comfort and less oral health related quality of life. Satisfaction with the oral situation after implantation depends on the outcome in eating comfort, speech comfort and esthetics. Modification in form and location of the teeth may affect speech. The aim of this study is to determine 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.
Methods: 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 a visual analog scale.
Results: Several speech sounds are found to be disturbed before treatment. In the next two stages of the treatment the number of speech issues decreases. In the final stage ten people show minor speech problems, especially with the /s/ sound. In this stage seven people still present with oromyofunctional problems, especially whistling problems. In this last stage people are very satisfied with the treatment (83%) and with speech (84%). The impact on quality of life is low (8.23/56).
