Abstract
Increasing attention has been drawn to the surgeon factor in the implant failure due to the implant fracture or osseointegration. The purpose of this study is to compare the location of implants placed by 2 surgeon groups, periodontal residents and professors, analyzing the distance between adjacent natural teeth and implants, or 2 adjacent implants. The charts and radiographs of patients who received dental implants between January 2014 and December 2015 in the Department of periodontology, Dankook University Dental Hospital were examined. A total of 1306 implants placed on maxillary and mandibular second premolar, first molar and second molar area were evaluated in this retrospective analysis. The implants were classified into two experimental groups: the implants placed posterior to the natural teeth and the implants placed posterior to the other implant. The implants in each group were also categorized into 3 subgroups by the location in the jaw whether they were in the second premolar, the first molar or the second molar areas. The distance was measured on the digital panoramic radiographs taken after the implant surgery. In the group of the implants placed posterior to the natural teeth, the distance between natural teeth and implants planted by the professors and periodontal residents were 2.94 ± 1.14 mm and 3.14 ± 1.24 mm, which showed significant difference. In the group of the implants placed posterior to the other implants, the distance between implants placed by the professors and periodontal residents were 3.35 ± 1.34 mm and 3.62 ± 1.41 mm, which showed significant difference. The implants placed in the first molar area showed significant difference in terms of the distance; 3.30 ± 1.14 mm by the professors, and 3.76 ± 1.10 mm by the periodontal residents. The following conclusion can be achieved on the basis of the results of this study. 1. In the group of the implants placed posterior to the natural teeth, the periodontal residents placed implant significantly more distally from the natural teeth than the professors. 2. In the group if the implants placed posterior to the other implants, the periodontal residents placed implant significantly more distally from the adjacent implant than the professors. In case of placing implants in the first molar area, the periodontal residents placed implant significantly more distally form the adjacent implant than the professors.
