この研究の目的は、総義歯装着者の臨床状態を推定することである。72名の患者が当歯科病院を受診した。検査は問診と臨床検査から構成された。客観的評価として、下部総義歯床の適合性試験を行い、ホワイトシリコンフィルムの厚さにより4群に分類した（A-zone 0-30μm、B-zone 30-70μm、C-zone 70-130μm、D-zone 130μm-）。結果 1.Aゾーン9.3%、Bゾーン35.8%、Cゾーン24.5%、Dゾーン30.4%であった。2.2.前歯部の適合性は、後歯部に比べて不良であった。3.3.下側総義歯の適合度と不適合と診断された歯科医師の判断との間には統計学的に有意な差があった．4.4.義歯のゆるみを訴えた患者と適合性試験との間に有意差が認められた．

The purpose of this study was to estimate the clinical condition of complete denture wearers. 72 patients came to our Dental Hospital according to our recall. The examination consisted of a questionnaire and clinical examinations. For objective evaluation, the fitness test of lower complete denture base was taken place and was classified into four groups by the thickness of the white-silicone film (A-zone 0-30 microns, B-zone 30-70 microns, C-zone 70-130 microns, D-zone 130 microns-). Results 1. The average ratio of four groups of the white-silicone film were A-zone 9.3%, B-zone 35.8%, C-zone 24.5% and D-zone 30.4%. 2. The fitness of anterior portion was ill fit in comparison with posterior portion. 3. There was statistically significant difference between the fitness of lower complete denture and dentist's judgment diagnosed as ill fit denture. 4. There was significant difference between the fitness test and the patients who complained about loose fit of the denture.
