Abstract
This study was conducted to clinically and radiographically evaluate the success of implant assisted overdenture in controlled type-1 diabetic patients.
Ten controlled type-1 diabetic and ten non-diabetic completely edentulous male patients were selected for this study with age ranging from 30 to 50 years. Patients participated in this study, were not smokers and free from any intra-oral or systemic diseases that may compromise implant treatment success other than DM.
All patients received three NR line Dentium implants in the inter-foraminal area of the mandible through minimally invasive flapless technique using CAD/CAM fabricated surgical templates.
All patients received systemic antibiotic treatment for eight days and used chlorhexidine rinse for two weeks starting one hour before surgery to minimize postoperative complications. Diabetic patients were instructed to take half their daily dose of insulin the morning of the surgical procedure as a stress dose to avoid hyperglycemia; then, after the intervention, the whole insulin dose was taken. The mini ball abutments were screwed on the implant on the same day of surgery to avoid second stage surgery. The height of the mini ball abutment was chosen according to the thickness of the trans-mucosal portion.
An acrylic complete mandibular overdenture opposed by maxillary conventional CD were fabricated for each patient with bilateral balanced occlusion. The mini ball attachments were connected intraorally by direct (pick up) technique under maximal biting force.

Screening tests, clinical and radiographic evaluations for the patients were scheduled at the time of final prosthesis insertion (base line), four months and one year after insertion.
Results of this study showed minimal changes that is within the conventional limits generally accepted for osseointegrated dental implants in clinical and radiographic parameters throughout the evaluation period.
from this study it can be concluded that: ❖ Despite that there was a difference between controlled type-1 adult diabetic and non-diabetic control groups regarding the change in the clinical and radiographic parameters, however, this difference was of little or no value when comparing the percent of change in the two groups. ❖ Survival rate of dental implants in well-controlled diabetic patients is 80% which is close to non-diabetics, so this disease, if properly controlled, is not a contraindication. ❖ Flapless minimally invasive technique using CAD/CAM fabricated surgical guides is associated with successful outcome of implant assisted mandibular overdenture in diabetic patients. ❖ The use of three narrow diameter implant with mini ball abutment is considered as predictable successful protocol for diabetic patients.
