背景:

従来型の総義歯に対する患者の評価は，総義歯の品質に影響される可能性がある．

BACKGROUND: Patients' appreciation of their conventional complete dentures might be affected by the quality of the dentures.

方法:

無歯顎患者33名を無作為に抽出し，従来の総義歯を装着してリハビリテーションを行った．3名の独立した研究者により，7つの臨床的基準に基づいて義歯を評価するための検査票を作成した．また，患者には，有効な義歯満足度尺度を記入させた．Pearson product-moment correlationと共分散分析により，相関関係を検討した．

METHODS: A random sample of 33 edentulous patients who were rehabilitated by means of conventional complete dentures participated in the study. Three independent investigators who underwent technique calibration evaluated the dentures on the basis of seven clinical criteria by using a validated examination form. The patients filled out a validated denture satisfaction scale. The author used Pearson product-moment correlation and analysis of covariance to identify possible correlations.

結果:

本研究の結果，ほとんどの患者が義歯に対して「まあまあ満足」から「とても満足」の間であることが示された．また，下顎と上顎の入れ歯を装着している患者の満足度はほぼ同じであり，下顎の入れ歯の安定性（P = .039）および下顎の入れ歯の保持力（P = .005）と入れ歯全体の満足度の間に有意な正の相関がみられた．一方，審美的なリップサポートと下唇のライン，咬合，上顎の安定性と保持力は，参加者の総合満足度と相関がなかった（P＞0.064）．

RESULTS: The study results showed that most patients were between "reasonably satisfied" and "very satisfied" with their dentures. The author found nominally higher satisfaction among those receiving both mandibular and maxillary dentures and significant positive correlations between the overall denture satisfaction score and the stability of the mandibular denture (P = .039) and retention of the mandibular denture (P = .005). In contrast, esthetic lip support and lower lip line, occlusion, and maxillary stability and retention were not correlated with participants' overall satisfaction level (P > .064).

結論:

本研究の結果，臨床的に安定した下顎義歯が患者の満足度を決定する最も重要な要素であることが明らかとなった．

CONCLUSIONS: The results of this study show that a clinically stable mandibular denture was the most important determinant of patients' satisfaction.

実践的意義:

本研究の結果は，臨床家が患者の期待に応えるために最も重要な義歯の品質パラメータを明らかにするものである．

PRACTICAL IMPLICATIONS: The study findings highlight the most important denture quality parameters that can aid clinicians in meeting their patients' expectations.
