I've received a Straumann bone level implant with an RC Healing Abutment customizable, D 7.0 mm (i think) on my front upper right tooth on August 10th, 2018. By December during my follow up, my dentist wanted to place temporary crown for an additional 2-3 months to "contour my gums", which he never mentioned before. Is this really necessary? Is the placement and removal of the temporary crown going to affect the strength of my implant? Do the cost and cons outweigh the benefits?
