The hypothesis tested in this pilot study was that materials used for the palatal region of a maxillary denture affect the comfort of the maxillary denture in xerostomic patients.
Xerostomic complete denture wearers were selected to test three different maxillary dentures that were made with different palatal materials. Each denture was worn for a period of 2 weeks. The Kapur Index was used to measure retention. The Oral Health Index Profile (OHIP) was used to determine the patient's perception of each denture after the 2-week period. At the end of the study, the patients were asked to select which of the three dentures they would like as their primary denture.
All participants chose the metal-palate dentures, and 4 of 5 selected the titanium-palate denture as their primary denture. Statistical analysis of the OHIP demonstrated that the metal-palate dentures were perceived as being more comfortable than the acrylic-resin dentures.
This pilot study suggests that for xerostomic patients who have worn complete dentures, their selection of a metal-palate denture as their primary prosthesis strongly suggests that these dentures have properties that make them more comfortable to the patient than acrylic dentures. Subjective patient measurements supported this conclusion that the metal-palate dentures were preferable, while the evaluation method available to the clinician failed to discriminate among the prostheses.
本初步研究中所检验的假设是，用于上颌义齿腭部的材料会影响口干患者佩戴上颌义齿的舒适度。
选择佩戴全口义齿的口干患者，测试三种采用不同腭部材料制作的上颌义齿。每种义齿佩戴2周。使用卡普尔指数测量固位情况。使用口腔健康影响程度量表（OHIP）来确定患者在佩戴2周后对每种义齿的感受。在研究结束时，要求患者选择三种义齿中他们希望作为主要义齿的那一种。
所有参与者都选择了金属腭托义齿，5人中有4人选择钛腭托义齿作为他们的主要义齿。对OHIP的统计分析表明，金属腭托义齿比丙烯酸树脂义齿感觉更舒适。
本初步研究表明，对于佩戴全口义齿的口干患者，他们选择金属腭托义齿作为主要修复体，强烈表明这些义齿具有使其比丙烯酸义齿更让患者舒适的特性。患者主观测量结果支持了金属腭托义齿更优的这一结论，而临床医生可用的评估方法未能区分这些修复体。
