Purpose: The aim of this retrospective study is to investigate implant success and bone loss in diabetic patients when compared to non-diabetic patients at the University of Maryland School of Dentistry. Materials and Methods: The electronic health record database and radiographs were reviewed for diabetic and non-diabetic patients receiving implants between 2011 and 2016. One or two implants per patient were selected. Results: 62 diabetic patients and 70 non-diabetic patients were included in the study to make up a sample of 203 NobelBiocare implants. Patient age, gender, medical history, dental history, and implant history were recorded. Conclusions: Diabetics exhibited significantly greater thread exposure than non-diabetics, controlling for patient age, smoking status, and months from implant placement. Smokers exhibited significantly greater thread exposure than nonsmokers, controlling for patient age, diabetic status, and months from implant placement.
