Abstract
This study was conducted to evaluate clinically and radiographically the success of single drilling implant system.
The study included thirteen patients of both genders. They were selected from the Outpatient Clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Alexandria University. Patients’ age ranged between 20-40 years, with an average age of 29.46±5.81 years.
Single drilling osteotomy was done and tapered implants were inserted. Two stage surgery and delayed loading protocol were performed in which implants allowed for osseointegration for three months without loading. After three months, the healing abutments were tightened for 1 - 2 weeks.
After three months, the healing abutments were removed and the final abutments were tightened and final crowns were delivered.
Patients were evaluated clinically post-operative and on the 3rd and 6th months after surgery for the following:
1- The presence of pain, tenderness or discomfort.
2- The presence of swelling, infection or any post-operative complications.
3- Measuring the implant stability quotient values with the Resonance frequency analysis.
Also, radiographic follow-up was performed using CBCT to assess the level of bone height and density around dental implants using on demand 3D program.
Research has shown the following results
Clinical results
It was recorded that during the study period all cases suffered the minimum level of pain and swelling, except one case that felt moderate postoperative pain and moderate discomfort in the third week after implant placement.
In only one case, peri-implant infection with suppuration and swelling in the operated area was found after three weeks of implant placement and grade III mobility registered in the first follow up month that was regarded as a failure case.
All patients continued the follow up period without any signs of infection, gingivitis, or peri-implantitis after implant placement or during the evaluation period.
None of the other implants showed any signs of mobility all over the evaluation period.
Radiographic results
Radiographic evaluation by on demand 3D program revealed a good bone healing around the implants during the follow up period.
There was a statistically significant increase in bone density around the implants throughout the evaluation period. The mean of peri-implant bone level increased throughout the follow up period.
