Dental implants are small screws designed to replace the root of a tooth and restore the physical appearance and the chewing function of patients with partial or full tooth loss. Dental implants are intended for use in either the upper and/or the lower jaw to support prosthetic devices, such as artificial teeth. By integrating with the jaw, they enable restorations that range from replacement of one single tooth to an entire arch of bridgework, or as stabilizing elements for overdenture applications. Dental implants are manufactured from titanium, which is both biocompatible and strong.
Patients must undergo a medical evaluation to determine whether the implant placement procedure poses any health risks, and whether any factors exist that may affect the healing capacity of either their bones or their associated soft tissues.
Who can receive dental implants?
Who should carefully consider dental implants?
Dental implants should not be used in patients that have inadequate amounts of bone to permit placement of implants in sufficient size and numbers to support their biomechanical loads. Mechanical failures, including fatigue fracture of implants, prosthetic screws, and/or abutment screws, may occur if dental implants are insufficient in size or number to support their biomechanical loads, or are not properly positioned. To reduce the risk of overload or fatigue failure, dentists must place the implants and design prosthetics to accommodate the physical or medical conditions of their patients, such as bruxism (i.e., grinding or clenching of teeth) or unfavourable jaw relationships.
