Straumann Implants: Bone Level vs. Tissue Level?

Authors

Dr. P asks:
I am seeking advice from Straumann Implant users. With the past 5 patients that I sent to periodontists and oral surgeons for placement of Straumann implants in the maxillary anterior region, some placed bone level implants while others used tissue level Standard Plus implants. It appears as though the more experienced periodontists and oral surgeons favored the tissue level implants for the maxillary anterior region. The bone level implant requires the additional step of making a temporary crown to shape and condition the gingival to develop an aesthetic emergence profile. My question is what factors determine the better choice for selecting a bone or tissue level implant in the maxillary anterior region? What are the advantages and disadvantages of each design?
