This study was designed to determine if the following two variables influence the predictability of the presence of the interproximal papilla between single implant supported crown adjacent to a natural tooth: a) the vertical measurement from the crest of bone on the natural tooth to the contact point, and b) the horizontal measurement from the platform of the implant to the adjacent tooth root. Retrospective data from a multi-private practice based research network (PBRN) and from a graduate teaching institution were analyzed specific to the maxillary anterior aesthetic zones. 116 patients who had 139 dental implants restored for at least 6 months, with mesial and/or distal sites (N= 253) were included in the analysis. Assessments of the implant position based on osseous crestal topography were conducted using standardized radiographs which were digitized and interpreted with “Access” software. The gingival papilla morphology was assessed using the Jemt Papillary Index from calibrated digital clinical photographs. Contrary to previously published data, our results indicate that the presence of interproximal papillae is independent of the vertical and horizontal measurements investigated.
