Design outcomes

Primary

Measure	Time frame
Nitrogen Balance (NB) for assessing nutritional response and to evaluate the adequacy of protein intake as well as to estimate current protein requirements	—

Secondary

Measure	Time frame
1. Patient overall satisfaction: Was significantly higher for the mandibular overdenture. In addition, mandibular overdenture patients were significantly more satisfied with chewing experience and retention of the lower denture. conversion from a lower conventional complete denture to an implant-retained overdenture increased retention of the prosthesis 2. Improvement in masticatory performance 3. Protein ingestion: limited effect has been observed	—
