 Secondary: To examine these associations relative to long-term effects of sub-optimal glycemic control on two different anatomicrestorative schemes fixed partial or removable complete Outcomes: Assessments include implant survival, implant-related biologic complications and resonance frequency analysis as a measure of implant stabilization. Outcomes will be analyzed relative to glycated hemoglobin levels HbA1c taken at 6-month intervals over the course of the study.
