Modern dental implants have a history of over 30 years, and the data generated worldwide states that 95% of implants can be expected to last for a period of 15-20 years + (accurate data collection started about 20 years ago), and predictions are that 90% of implants should last a lifetime in correct conditions.
Bone grafting is generally needed if a tooth has been missing for a long time. During the first year of missing a tooth, bone is lost at double the rate of normal bone loss. This makes early placement of the artificial root critical to reducing the cost of dental implants and to reducing the amount of time that the dental implant process will take. Dental Implants Phase 2 â Artificial Root Placement. In Phase 2, the artificial root is placed in the bone and allowed to heal. The procedure itself takes 1 to 2 hours and the healing time is 3 to 6 months. During this time the titanium alloy (the same material used in joint replacement) implant will heal around and merge with the surrounding bone tissue. No other load bearing medical implant has as rapid healing or recovery times. Dental Implants Phase 3 â Placement of the Crown In Phase 3 an artificial tooth or crown is placed on the artificial root previously set into your jaw.
