To determine the survival rate, incidence of prosthetic complications, and patient satisfaction of implant fixed complete dental prostheses (IFCDPs) after a mean observation period of 1.4 years.
Twenty-eight (28) eligible participants were recruited according to specific inclusion and exclusion criteria. The definitive metal-acrylic resin IFCDPs consisted of titanium bars veneered with acrylic resin and acrylic denture teeth. Prosthodontic complications, divided into major and minor, were monitored. Parameters such as gender, jaw location, bruxism, and occlusal scheme were evaluated. Moreover, a questionnaire was administered throughout the study to assess patient satisfaction. Poisson regression as well as repeated measures ANOVA were used for statistical analysis.
Fourteen (14) males and 14 females were enrolled and followed-up at 3, 6, and 12 months. All IFCDPs survived (100% survival rate). The most frequent minor complication was the loss of material used to close the screw access hole (20% out of total complications). The most frequent major complication was chipping of the acrylic denture teeth (77.14% out of total complications). Gender (p = 0.008) and bruxism (p = 0.030) were significant predictors for the total major complications (major wear and major chipping) while occlusal scheme was a significant predictor for major chipping events (p = 0.030).
While IFCDPs demonstrated high prosthetic survival rates, they also exhibited a high number of chipping events of the acrylic veneering material, especially in males, bruxers, and individuals with canine guidance occlusion. However, the occurrence of these prosthetic complications did not negatively affect patient satisfaction.
确定在平均1.4年的观察期后，种植固定全口义齿（IFCDP）的生存率、修复并发症发生率及患者满意度。
根据特定的纳入和排除标准招募了28名符合条件的参与者。最终的金属-丙烯酸树脂IFCDP由钛棒和丙烯酸树脂贴面以及丙烯酸义齿牙组成。对分为主要和次要的修复并发症进行监测。评估性别、颌位、磨牙症和咬合方案等参数。此外，在整个研究过程中进行问卷调查以评估患者满意度。采用泊松回归以及重复测量方差分析进行统计分析。
纳入14名男性和14名女性，并在3、6和12个月时进行随访。所有IFCDP均存活（生存率100%）。最常见的次要并发症是用于封闭螺丝通道孔的材料丢失（占总并发症的20%）。最常见的主要并发症是丙烯酸义齿牙崩裂（占总并发症的77.14%）。性别（p = 0.008）和磨牙症（p = 0.030）是总主要并发症（严重磨损和严重崩裂）的显著预测因素，而咬合方案是严重崩裂事件的显著预测因素（p = 0.030）。
虽然IFCDP显示出较高的修复生存率，但它们也表现出丙烯酸贴面材料的大量崩裂事件，尤其是在男性、磨牙者和具有尖牙引导咬合的个体中。然而，这些修复并发症的发生并未对患者满意度产生负面影响。
