The extent of bone resorption is related to both the texture of the surfaces of the implant and abutment at and the morphology of the implant-abutment junction (IAJ). A number of investigators have zeroed in on the proposed inflammatory cell infiltrate that forms a zone around the IAJ. Although not yet fully understood, the current theory of the benefit of platform switching is related to the physical repositioning of the IAJ away from the outer edge of the implant and the surrounding bone, thereby containing the inflammatory infiltrate within the width of the platform switch. It is the MAGNITUDE of the platform switch that really makes the difference in that when the difference is greater than 0.8mm there was a statistically significant difference in the level of bone maintenance. 19 Articles published..

If Buccal Plate: and want to maintain papillae.. igap i=immediate Implant

10 As a general rule, if you create a contact point 5mm or less from the crestal bone you will insure a papilla will exist in that embrasure 147 Distance from contact point to crest of bone (mm) % of papilla filling in the embrasure Soft Tissue Management Contact Point Index CPI Impression
