title: Impact of anterior single-tooth implants on quality of life, articulation and oromyofunctional behaviour: a pilot study.
abstract: The main purpose of this study is to determine the impact (one and a half year after implantation) of a single-tooth implant on articulation and oromyofunctional behaviour. This information is important for dentists, orthodontists or stomatologists who treat professional speakers. Objective (acoustic analysis) as well as subjective (questionnaire, phonetic inventory, phonetic analysis, oromyofunctional assessment of lip and tongue function, blowing, sucking and swallowing) assessment techniques were used to determine the quality of life, articulation and oromyofunctional behaviour. Fourteen subjects who received a single-tooth implant and a control group of nine subjects participated in this study. The mean overall satisfaction of single-implant users was 95%. The subjects who received a single-tooth implant were capable of producing all Dutch vowels and consonants. The phonetic analysis revealed a sigmatism in 57% of the cases. Sigmatisms (stridens sigmatism followed by simplex sigmatism) were the most frequently observed phonetic disorders. There was interobserver agreement about normal lip and tongue functions. Moreover, blowing, sucking and swallowing patterns were normal (concordance value 96%). Detailed analyses 1 or 2 years after implantation of an anterior single-tooth implant revealed normal speech intelligibility and oromyofunctional behaviour. Articulation was characterised by the presence of a persistent phonetic disorder. Further research involving more subjects with an anterior single-tooth implant is needed.
