A new implant design for optimal esthetics and retention of interproximal papillae

A biologically derived, parabolic implant design that has an occlusal platform that mimics the cementoenamel junction of natural dentition is proposed and described. The interproximal areas of the platform are more coronal than the facial and lingual areas of the platform, and follow the anatomical contours of the alveolar bone. The principle behind this parabolic margin, as opposed to a flat and monoplane margin, is that any bone remodeling that follows would replicate a parabolic form. This design helps to maintain bone more coronal on the proximal surfaces than on the facial and lingual surfaces, hence preserving the bone support of the gingival papillae.
