The purpose of this controlled study was to determine the impact of a single-tooth implant, fixed implant prosthesis and completely removable dental prosthesis on intelligibility, articulation and oromyofunctional behaviour. Additionally, the self-perceived overall satisfaction of the dental replacements and the effect on speech was questioned. Objective (acoustic analysis) as well as subjective assessment techniques (perceptual evaluation) were used. The satisfaction of single-tooth implant group was very high (100%) followed by a satisfaction of 87% for the fixed implant prosthesis group and 68% for the removable prosthesis group. The results of the phonetic analyses revealed a normal intelligibility and oromyofunctional behaviour in the three groups of dental replacements. Only one type of articulation disorders was observed in the single-tooth implant group, followed by three types of disorders in the removable prosthesis group and six types of disorders in the fixed implant prosthesis group. In this last group, not only 87% of the subjects showed distortions of one or more consonants but also most consonants of the Dutch language were disturbed in comparison with the single-tooth implant and removable prosthesis users. Special attention must be paid to the fricative /s/ because in more than 50% of all groups, this sound is disturbed.
本对照研究的目的是为了确定单颗牙种植体、固定种植义齿修复体和全可摘义齿对可理解度、发音清晰度和口颌运动功能的影响。此外，还调查了患者对义齿修复体的总体满意度以及对语音的影响。使用了客观（声学分析）和主观评估技术（感知评估）。单颗牙种植体组的满意度非常高（100%），其次是固定种植义齿组（87%）和可摘义齿组（68%）。语音分析结果表明，三组义齿修复体的可理解度和口颌运动功能正常。仅在单颗牙种植体组观察到一种类型的发音障碍，在可摘义齿组观察到三种类型的发音障碍，在固定种植义齿组观察到六种类型的发音障碍。在固定种植义齿组中，不仅 87%的患者出现一个或多个辅音的扭曲，而且与单颗牙种植体和可摘义齿患者相比，荷兰语的大多数辅音也受到干扰。必须特别注意摩擦音/s/，因为在所有组中，超过 50%的患者的这个音受到干扰。
