The use of an appropriate drill is vital for achieving clinically sufficient osseointegration. In the present study, we evaluated the clinical results for dental implants placed with a trephine bar compared with those for dental implants placed with a regular drill. A total of 40 dental implants (20 patients, 7 males and 13 females) were evaluated. The experimental group consisted of 20 dental implants placed using a trephine bar, and the control group consisted of 20 implants placed using a regular drill in accordance with commercial protocol. During clinical examination, the bone loss and gingival infection around the dental implants, mobility of the implants, and discomfort on chewing were scored and evaluated. No significant differences were found between the two groups. These results suggest that usage of the trephine bar does not influence the prognosis of postoperative dental implant placement.
