Final answer:
A healing collar is used in a two-stage implant procedure to shape the gum tissue and prepare for the placement of the final implant crown or prosthesis after the dental implant has integrated with the jawbone.
Step-by-step explanation:
A "healing collar" is used in a two-stage implant procedure. This procedure is part of dental implantology, a branch of dentistry focused on the placement of dental implants. The healing collar, also known as a healing cap, is specifically utilized after the first stage of the procedure, in which the dental implant is surgically placed into the jawbone.
In the second stage, after the implant has integrated with the bone, which can take several months, the healing collar is attached onto the top of the implant. This process helps to shape the gum tissue and create space for the final implant crown or prosthesis. It is a crucial step in ensuring the proper healing and preparation of the site before the final restoration is placed.
