To provide adequate room to establish emergence profile the implant platform should be 3 to 4 mm apical to the mid-facial gingival margin when a 2-stage dental implant system is used. This may require reduction of the osseous crest by scalloping the bone so that the mid-facial osseous crest is 3-4 mm apical to the mid-facial gingival margin. This may result in a sub-crestal position of the interproximal implant platform (measured as a negative number). The top of the implant will be even with the crestal bone. The implant used will be any dental implant. At the time of surgery the implant platform will be placed even with the mid-facial osseous crest if a two-stage implant is used.
