Diabetes mellitus has long been considered a relative contraindication to dental implant therapy. The aim of this review was to assess the impact of diabetics glycaemic control on dental implant survival.
The authors conducted a search of the Medline database and the references of identified articles that assessed implant survival or failure for patients with diabetes. They included prospective and retrospective studies in French, German, and English language with at least 10 patients.
16 studies with follow-up periods of 4 months to 12years were finally included and they found:-
- Implant failure rates for diabetic patients ranged from 0% to 14.3%.
- The identification and reporting of glycemic control was insufficient or lacking in 13 of the 16 studies,11 only enrolling patients deemed as having acceptable glycemic control, limitinginterpretation of findings relative to glycemic control.
- Three of the 16 studies having interpretable information on glycemic control failed to demonstrate a significant relationship between glycemic control and implant failure, with failure rates ranging from 0% to 2.9%.
The authors concluded
Clinical evidence is lacking for the association of glycemic control with implant failure while support is emerging for implant therapy in diabetes patients with appropriate accommodations for delays in implant integration based on glycemic control. The role for implants to improve oral function in diabetes management and the effects of hyperglycemia on implant integration remain to be determined.
