Abstract

PURPOSE
To Analyse clinical treatment outcomes and prognosis of patients who have received narrow diameter implants due to anterior tooth loss, and to assess long-term success measured through radiological examination. MATERIAL AND METHODS: From December 2006 to June 2017, Thirty-six patients were selected, and fifty-two narrow diameter implants were inserted by 1 surgeon. All prosthetic appliance were fabricated by the two prosthodontist. The dental records of each patient were reviewed. Measuring of marginal bone loss and accessing implant success rate were performed.
RESULTS
Thirty-nine NR lines (Dentium, Suwon, Korea) and thirteen Slim lines (Dentium, Suwon, and Korea) were inserted. The implant used was 2mm to 4.3mm in diameter and 9mm to 12mm in length. NR line implant success rate was 87.2%, survival rate was 92.1%, and Slimline line implant success rate was 92.3%, and survival rate was 92.3%. The average marginal bone loss was 0.22±0.4 mm and 0.07 ± 0.23 mm respectively.
CONCLUSION
The narrow diameter implant is a reliable implant treatment that can be used in patients with problems with tooth loss. The success rate between the NR line and the slim lines implant was not significantly different and was clinically acceptable.
