Scientific titleThe effect of improved oral prostheses on the nutritional state of elderly edentulous individuals: a randomised controlled trial
Study acronymSIN II
Study objectivesNull Hypothesis:
That there will be no difference in nutritional status measured by serum homocysteine levels in elderly edentulous males and females wearing mandibular 2-implant overdentures and those wearing mandibular conventional dentures at six months following delivery of the prostheses.
Ethics approval(s)McGill University Faculty of Medicine IRB, original approval received November 15, 2002; renewed yearly; latest renewal approved 29 August 2006 (study number A08-M75-02B).
Health condition(s) or problem(s) studiedEdentulism (lack of all teeth)
InterventionControl: Complete conventional dentures

Experimental: Mandibular 2-implant overdenture with ball attachments and maxillary conventional denture
Intervention typeOther
Primary outcome measureSerum level of homocysteine.
Secondary outcome measures1. Patient satisfaction
2. Vitamin status
3. Changes in serum albumin
4. Changes in dietary habits
5. Changes in function
6. Cost effectiveness
Overall study start date01/09/2002
