a visual analog scale. 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).
Conclusion: Speech and oromyofunctional problems occur during all stages of the treatment. Especially the /s/ sound and the whistling function seem very fragile and occur in all stages. People are very satisfied with their oral and speech situation in this last stage, despite the fact that speech therapists detect some difficulties with the pronunciation of in particular the /s/ sound.

Paper 4 aimed to investigate the impact of implant-supported rehabilitation on quality of life and social participation taking into account patient’s personality. Fifty-four patients were included in this study and assigned to either a single unit group (n=15) or a complete jaw restoration group (n=39). Of the 54 participants, 49 nominated an external observer who can evaluate the daily behavior of the patient. Before and after treatment patients and their external observer completed the OHIP-14, the NEO-FFI and the MSPP questionnaires respectively focusing on Oral Health related Quality of Life, Personality and Social participation. The correlations between self- and observer ratings on pre and post treatment outcomes on were insignificant (QoL pre: p=0.086, post: p=0.115, freq. soc. part pre: p=0.944, post: p=0.876, div. soc. part pre: p=0.798, post: p=0.167), suggesting considerable differences in observer perspectives. The traits Neuroticism, Extraversion and Agreeableness were associated with QoL. Openness, Conscientiousness and Agreeableness were associated with social participation. Patients in the complete jaw restoration group reported more impact of the implant treatment on quality of life as compared to the single unit group (p=0.007). The complete jaw restoration group reported an improved quality of life after treatment and significant increases of both frequency (p=0.001) and diversity of social participation (p=0.036).
