We conducted a randomized clinical trial to determine whether providing simple mandibular implant overdentures (IODs) to elderly individuals would give them a significantly better nutritional profile than those who receive complete dentures (CDs). Two hundred fifty-five edentate patients > 65 yrs were randomly assigned to receive maxillary CDs and mandibular IODs (n = 128) or CDs (n = 127). Six-month and one-year post-treatment outcomes were blood plasma levels of homocysteine (tHcy), vitamin B12, vitamin B6, albumin, serum folate, and C-reactive protein concentrations, as well as dietary intake. The association between treatment and tHcy levels was not statistically significant. A decline of folate from baseline values in both study groups, as well as those of vitamins B6 and B12 and albumin, was observed. Significant between-group differences were detected in food preparation and in the individuals' ability to chew a variety of foods. This study suggests that implant overdentures do not have a more positive effect on the nutritional state of elderly edentate individuals at 6 and 12 mos post-treatment than new complete dentures. However, those wearing IODs are significantly more likely to take in their nutrients through fresh, whole fruits and vegetables.
我们进行了一项随机临床试验，以确定为老年人提供简单的下颌种植覆盖义齿（IOD）是否会比那些接受全口义齿（CD）的患者在营养状况方面有显著改善。255 名无牙颌患者（年龄>65 岁）被随机分配接受上颌 CD 和下颌 IOD（n=128）或 CD（n=127）治疗。在治疗后 6 个月和 1 年时，评估了同型半胱氨酸（tHcy）、维生素 B12、维生素 B6、白蛋白、血清叶酸和 C 反应蛋白浓度以及饮食摄入等血液生化指标。治疗与 tHcy 水平之间的关联没有统计学意义。两组患者的叶酸以及维生素 B6、B12 和白蛋白水平均从基线值下降。在食物准备和咀嚼各种食物的能力方面，两组之间存在显著的组间差异。本研究表明，与新的全口义齿相比，种植覆盖义齿在治疗后 6 个月和 12 个月对老年无牙颌患者的营养状态没有更积极的影响。然而，佩戴 IOD 的患者更有可能通过新鲜的、完整的水果和蔬菜来摄取营养。
