Abstract :
[en] Background: According to Choquet and Tarnow principles (2001), a papilla is always present if the distance from the base of the contact point between two crowns to the crest of the bone is 5 mm or less. The arrival of new designs in implantology suggested more tissue preservation and so a possible evolution for the aesthetic treatments. Aim: This study was designed to determine whether the distance from the base of the contact point to the crest of the bone would correlate with the presence or absence of the interproximal papillae adjacent to single-tooth implants using the recent implant designs. Methods: A clinical, photographical and radiographical retrospective evaluation of the papilla level around single dental implants and their adjacent teeth was performed in the anterior maxilla in 34 patients restored with 39 implants. These implants were loaded at least 6 months and present a modified profile (Implants : NobelConcept and NobelActive, Nobel Biocare ; Bone Level, Straumann. Abutments : Platform-switching and curvy). Sixty-three papillae were available for evaluation. The Jemt index, the vertical distance between the base of the contact point and the bone crest, the distance from the papilla level to the contact point were measured. The measurements were rounded off to the nearest 0,001 millimeter and used with calibration computer programs (ImageJ) to be analyzed. The statistical analyses were realized with SAS program (SAS Institute, Cary, NC, USA). Results: When the measurements from the contact point to the crest of bone was 5 mm or less, the papilla was present 100% of the time. When the distance was 6 mm, the papilla was present 96% of the time. And when the distance was 7 and 8 mm, the papilla was present 57,14% and 50% of the time. Conclusions and clinical implications: These results show the influence of the bone crest on the presence or absence of papillae between implants and adjacent teeth. The data also show a positive influence for recent designs of implant and abutment systems. This designs shift the actual critical bone distance under the contact point from 5mm to 6mm and could improve the aesthetic outcome.
