Current research: small-diameter implants continue to gain positive research support

Aug. 4, 2011
Dr. Gordon Christensen discusses recent research into implants in patients with limited tooth-to-tooth space and offers his recommendations.

By Gordon J. Christensen, DDS, MSD, PhD

Thirty-one implants with a maximum diameter of 3.0 mm were placed in 17 patients who had limited tooth-to-tooth space. Standardized radiographs were made at six and 12 months accompanied with conventional measurement of soft-tissue and bone conditions. Slight bone loss was shown at six months with no significant progression after that time.

The overall survival rate was 96.7%. The investigators concluded that “the use of one-piece narrow-diameter immediately loaded implants appears to be an effective prosthetic treatment for areas of limited space.”

Dr. Gordon Christensen comments: Mini implants are viable options for those patients who may not be able to receive conventional-diameter implants. I welcome you to take our popular course on mini implants. Visit for more information.
