Dental implants are regarded as a standard of care in restoring missing teeth. Although there is a high prevalence of diabetics who receive dental implants, the relationship between dental implants and diabetes has not clearly been investigated.

A total of 30 subjects (15 patients with type II diabetes and 15 non-diabetes subjects) who have dental implants will be recruited. The purposes of this research study are: (1) to evaluate diabetes patients to determine risk factors for bone loss at dental implants and teeth; and (2) to evaluate bone-resorptive biomarkers (proteins related to bone loss) present in saliva and blood serum, comparing the two groups.

Primary Outcome Measures:
  • Gather pilot data on our ability to longitudinally evaluate partially edentulous patients afflicted by diabetes mellitus with functional dental implants to determine clinical risk factors for progressive alveolar bone resorption at implants and teeth.
