The aim of this prospective, randomized clinical trial was to evaluate the effect of a minimally invasive implant procedure for denture stabilization on patients' quality of life (QoL).
Thirty totally edentulous patients were selected for this study. All prostheses were adjusted and relined before randomization and allocation to treatment either with two small diameter implants (SDI) - retained overdenture (study group) or non-intervention group (control group). Quality of life was assessed using the Oral Health Impact Profile-EDENT (OHIP-EDENT) questionnaire before intervention and at one-year follow-up. Between-group comparisons were carried out using the non-parametric Mann-Whitney test.
Magnitude of change in the OHIP-EDENT total score at one-year follow-up was 25.4 ± 10.7 for the study group, revealing a statistically significant difference with the control group, that showed a change of 9.5 ± 8.3 (P = < 0.001).
After one-year follow-up, patients wearing mandibular overdentures with two minimally invasive splinted SDI, experienced more improvements in perceived oral health-related quality of life, than patients having conventional treatment.
这项前瞻性随机临床试验的目的是评估一种用于义齿稳定的微创种植手术对患者生活质量（QoL）的影响。
本研究选取了30例全口无牙患者。在随机分组并分配至使用两颗小直径种植体（SDI）固位的覆盖义齿治疗组（研究组）或非干预组（对照组）之前，对所有义齿进行了调整和重衬。在干预前和一年随访时，使用口腔健康影响程度量表-无牙版（OHIP-EDENT）问卷评估生活质量。组间比较采用非参数曼-惠特尼检验。
研究组在一年随访时OHIP-EDENT总分的变化幅度为25.4±10.7，与对照组相比有统计学显著差异，对照组的变化为9.5±8.3（P = < 0.001）。
经过一年随访，与接受传统治疗的患者相比，佩戴带有两颗微创夹板式SDI的下颌覆盖义齿的患者在口腔健康相关生活质量方面有更多改善。
