The purpose of this study was to evaluate experimental peri-implant breakdown microbiologically, radiographically and histologically. @entity692 -coated, @entity702 plasma-sprayed, and @entity702 alloy surfaces were investigated. Eighty-four implants were placed in 14 @entity235 . Standardized radiographs and microbiologic samples (DNA) were obtained. @entity235 were sacrificed at 3 and 6 months. Undecalcified histologic sections were prepared. Thickness of @entity692 coating, changes in crestal bone height, and marginal changes in osseointegration were measured. Vertical @entity604 was computed. Radiographs were analyzed using computer-assisted densitometric image analysis (CADIA). Microbial analysis (DNA) did not clearly favor any of the examined surfaces. CADIA did not show differences among implant surfaces. No significant differences among the three implants were noted for histometry, except the experimental @entity702 plasma-sprayed surface showed an increase in vertical @entity604 6 months (P < .05). Thickness of @entity692 was decreased in active @entity737 (P < .05). Clinical attachment level was shown to be the most sensitive clinical parameter for detecting histologic changes. All implants were equally susceptible to @entity737 .
