Evaluation of a Single-Tooth Implant
Johnson, Robert H. / Persson, G. Rutger
Fifty-nine commercially pure titanium implants in 59 subjects were compared with internal control teeth for 3 years. Nineteen coated implants of identical design were placed in 17 of the subjects and compared with the titanium implants. Demographic data, microbial DNA, aspartate aminotransferase levels, Plaque Index, width of adjacent keratinized tissue, probing depths, bleeding on probing, relative attachment levels, mobility, and radiographic bone height were studied. The only statistically significant changes over time were improved plaque scores in the subjects and slight bone loss around the implants. There were no differences between the 2 types of implants. Mobility was less and probing depth and bleeding on probing were greater in the implant sites than in the control sites.
