  • The purpose of this study is to compare the buccal soft tissue changes occurring around single-tooth replacements in the maxilla using three different implant-abutment interface designs over a one year period. The study was an open, prospective, randomized multicenter study in 141 subjects. Subjects were randomized to Group A (Conical interface, n=48), B (Flat-to-flat interface, n=49) or C (Platform switch, n=44). This study evaluated the soft tissue changes longitudinally through collection of standardized oral photographs using Canfield apparatus. Comparisons between restorative platform types and between time points were evaluated statistically. There was not statistically significant change of buccal soft tissue level (mean -0.1 ± 0.7 mm) at 12 month followed implant placement, with no statistically significant difference between three implant abutment designs. Overall papilla height showed slight increase (mesial papilla 0.3±0.5 mm, distal papilla 0.2±0.5 mm), with no statistically significant difference between treatment groups.
