知的障害者に磁性アタッチメントを応用したインプラント義歯の1症例

抄録

Purpose: We report that a mentally disabled patient's masticatory function and esthetics were improved by applying the implant overdenture system by using a magnetic attachment.
Case: The patient was a 56-year-old female. The chief complaint was disturbance of masticatory function because of ill-fitting of the upper jaw denture. The case was complicated because the patient was seriously mentally disabled and attended an institution for the mentally disabled in daily life. Oral findings were edentulous upper jaw 2 years ago and the lower jaw had only 2 teeth.The alveolar bone of the upper jaw showed remarkable bone resorption and the tongue and lips showed extramovement.
Operation and Course: We performed surgical insertion of 7 ITI^® implants around the 832｜2378 regions under intravenous sedation. Six months later, we carried out a second operation to implant the Platon^® magnetic head system, and then completed the upper overdenture without palatal base by using the magnet of Hitachi^® High Colex. After completing the overdenture, the patient showed remarkably improved masticatory function and esthetics, and reduced extra-movement of the tongue and lips. We are now performing a regular check-up every three months.
Discussion and Conclusion: We found that implantation for the mentally disabled patient involved many difficult factors such as whether the implant was done by surgical operation or not, and maintenance of oral condition was poor because of poor oral hygiene. In this case, the implant overdenture system by using magnetic attachment was shown to improve QOL for the mentally disabled patient and was very useful.
