Dental implants were invented in 1952 by a Swedish orthopedic surgeon named Per-Ingvar Brånemark. A dental implant is a surgical fixture that is placed into the jawbone and allowed to fuse with the bone over the span of a few months. The dental implant acts as a replacement for the root of a missing tooth and holds a replacement tooth or bridge. Having a dental implant fused to the jawbone is the closest thing to mimicking a natural tooth because it stands on its own without affecting the nearby teeth and has great stability. The process of fusion between the dental implant and jawbone is called "osseointegration." Most dental implants are made of titanium, which allows them to integrate with bone without being recognized as a foreign object in our body. Over time, technology and science have progressed to greatly improve the outcomes of dental implant placement. Today, the success rate for dental implants is close to 98%.
When it comes to tooth replacement, generally, there are three options: (1) removable dental appliance (full denture or partial denture), (2) fixed dental bridge (cemented), and (3) dental implant. Deciding on which option to choose depends on many factors. Specifically for dental implants, these factors include:
quantity and quality of the jawbone where the dental implant is to be placed
health of the patient
location of missing tooth or teeth
Dental implants can be used to replace a single tooth, several teeth, or all of the teeth. The goal of teeth replacement is to restore function as well as esthetics. A dentist examines the area to be considered for the dental implant and makes a clinical assessment of whether the patient is a good candidate for a dental implant.
There are great advantages to choosing a dental implant for tooth replacement over the other options. Dental implants are conservative in that missing teeth can be replaced without affecting or altering the adjacent teeth. Furthermore, because dental implants integrate into the bone structure, they are very stable and can have the look and feel of one's own teeth.
