The process of a dental implant begins with a tooth extraction. The patient then needs to wait around 2 months for the gum to heal. After this, the implant is placed and gum is stitched, with the patient then having to wait about 3-4 months. In this time, the bone will grow into the implant micro-porosities and the implant gets fused to the bone. This process is call osseointegration.
After this, the dentist will make a punch hole in the gum, access the top of the implant, do the necessary measurements and get the crown or any other restoration made by a dental lab. When the restoration is ready, the dentist will screw that into the implant and the job is done.
