Objectives: This randomized clinical trial studied whether IOD and CD patients consumed different amounts of total dietary fiber (TDF), macronutrients, nine micronutrients and energy (kcal).
Methods: Two hundred fifty-five male and female edentate patients (> 65 yrs) were randomly divided into two equal groups and assigned to receive a maxillary CD and either an IOD or a CD for the mandible. Two hundred seventeen participants (CD = 114, IOD = 103) completed the one-year protocol, then reported the food types and quantities they consumed to a registered dietician through a standard 24-hour recall method. The data collected were analyzed using nutrient values from the Canadian Nutrient File with the help of a specialized software from the McGill University Faculty of Dietetics and Human Nutrition. The mean values of TDF, macro- and micronutrients and energy consumed by both groups were calculated and compared analytically.
Results: No significant between-group differences were found on energy, TDF or any of the 12 nutrients analyzed.
Conclusions: Despite the proven and theoretical advantages of IODs, this adequately-powered study reveals no evidence of nutritional advantages with two-implant mandibular overdentures over conventional complete dentures in the dietary intake of TDF, macronutrients, nine micronutrients or energy intake at one year following prosthesis delivery.
