title: Implant overdentures and nutrition: a randomized controlled trial.
abstract: 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.
