UNASSIGNED: The current study was conducted in the outpatient Prosthodontic Clinic, Faculty of Dental Medicine, Al-Azhar University, Cairo, Egypt. PrMA was evaluated in 45 completely edentulous patients (46% males, mean age 50.4 ± 4.7 years). Each patient received a thermoplastic PMMA complete denture (Polyan IC TM Bredent GmbH & Co.KG, Germany). The PrMA was evaluated at one-month and six-month intervals of denture use. An immediate loading single implant was placed into the mid-symphyseal for each patient, and the denture was adjusted. Subsequently, the PrMA was reevaluated after one month and six months. The data were collected and statistically analyzed using the SPSS@V25 to assess the changes in PrMA.
UNASSIGNED: The PrMA demonstrated improvement after six months of thermoplastic conventional denture use. However, this improvement was not statistically significant (p = 0.405). In addition, the PrMA showed a substantial increase following a single implant placement at one and six months (p < 0.001) of the overdenture use compared to the conventional denture. The PrMA insignificantly improved (p = 0.397) after six months of the single implant retained overdenture use.
UNASSIGNED: The study\'s findings indicate that using immediate loading single implant-retained mandibular overdentures significantly improved PrMA in completely edentulous patients.
■目前的研究是在门诊病人口腔修复诊所进行的,牙科医学院,Al-AzharUniversity,开罗,埃及。在45例完全无牙患者中评估了PrMA(46%的男性,平均年龄50.4±4.7岁)。每位患者都接受了热塑性PMMA全口义齿(PolyanICTMBredentGmbH&Co.KG,德国)。在义齿使用的一个月和六个月间隔评估PrMA。每位患者都将立即加载的单个植入物放置在中间联合处,并调整了义齿。随后,在1个月和6个月后重新评估PrMA.收集数据并使用SPSS@V25进行统计分析,以评估PrMA的变化。
■PrMA在使用热塑性传统义齿6个月后表现出改善。然而,这一改善无统计学意义(p=0.405).此外,与传统义齿相比,在使用覆盖义齿的1个月和6个月(p<0.001)时,一次植入物放置后,PrMA显着增加。单个种植体保留覆盖义齿使用六个月后,PrMA无明显改善(p=0.397)。
■研究结果表明,在完全无牙患者中,使用即刻加载单种植体保留的下颌覆盖义齿可显着改善PrMA。
