Experimental peri-implantitis in consecutively placed, loaded root-form and plate-form implants in adult Macaca mulatta monkeys.
This study is part of an on-going project describing the character of round- and plate-form implants placed in a primate model. In this paper 20 loaded plate-form and 23 root-form implants were connected to prostheses and experimental peri-implantitis was induced by ceasing scaling procedures and placing braided silk ligature around the implants. Twenty-four prostheses utilizing natural teeth were studied for comparison. Clinical measurements were carried out monthly for 6 months and radiographic measurements at 3 and 6 months post-ligature placement and cessation of scaling. Both root-form implants and plate-form implants showed a significant loss of crestal bone height at 3 and 6 months after ligature placement (P < .001 after 6 months). The difference in bone loss between plate- and root-form implants, however, was not significant.
