Edentulous persons have poor diet quality demonstrating a need for dietary intervention. Implant-supported mandibular overdentures (IODs) have functional advantages over conventional dentures (CD), but whether they enhance the ability to eat more healthily following dietary advice is unknown.


This study aimed to compare the effectiveness of dietary intervention between IODs and CD patients.


Edentulous adults (28 IOD and 26 CD) received customised dietary advice. The percentage contribution of dietary fats, carbohydrate and protein to energy (kcal) intake, dietary intakes of fibre, fruits, vegetables and antioxidants, and plasma antioxidants were assessed pre- and at 3 and 6 months post-dietary intervention.


Both groups increased fruit and vegetable intake at 3 and 6 months following dietary intervention but intakes between groups did not differ. The IOD group had reduced % energy from total fat at 3 and 6 months and from saturated fat at 3 months. The CD group had reduced % energy from saturated by 6 months. The IOD group had a significantly lower % energy intake from saturated fat at 3 months and higher intake of non-starch polysaccharide (NSP) compared with the CD group. Both groups showed improvements in serum antioxidant status but the IOD group had significantly higher plasma antioxidant capacity post intervention compared with the CD group.


Dietary intervention benefits denture patients. IOD patients showed moderately greater dietary improvements compared with conventional denture patients.
