In each of 17 patients, a 'platform-switched' implant was placed using a conventional two-stage procedure in a posterior sextant. At least 6 months after restoration, measurements were recorded from standardised radiographs. The tip of the papilla was identified using a radio-opaque material. 'Perfect papilla fill' was observed in a third of subjects and occurred if the distance from the implant/tooth contact area to the crestal bone was less than 5 mm. Multiple linear regression analysis revealed that the bone level at the adjacent tooth had a significant influence on whether or not there was papilla fill. Such a relationship was not shown for the bone level at the implant. The investigators however, did not examine if the distance between the implant and adjacent tooth influenced their conclusion.
