The use of titanium material for tooth implants has been around since 1960. However, some patients still have allergic reactions to the material since it’s a type of metal. In effect, dental practitioners searched for other alternatives. That is until they discovered ceramic dental implants in the late 80’s.
Ceramic implants are artificial tooth roots that dentists place into the patient’s jawbone. Instead of metal, they use zirconia as the main component for this type of implant. Three months following a tooth implant procedure, bones grow around these artificial roots. This is a natural process they call as osseointegration. In essence, implants become a part of the human body, making them a sturdy base for dental prosthesis.
Previously, the aluminum oxide was the main component of a ceramic tooth implant. The material was fortunately compatible to the human body. However, it gave poor results so the dental industry put a stop to its use in 1990. Since then, dentistry uses zirconia in making ceramic implants.
Today, dentists use two types of tooth implants which is helping them gear towards metal-free implant restorations.
Two kinds of ceramic dental implants
Single-piece ceramic implant
Traditionally, ceramic dental implants made of zirconia are in one piece. Its artificial tooth root and connector or abutment are attached to one another. With one-piece implant technique, dentists position the abutment to a desired angle. Furthermore, this type of implant needs more depth to hide the dental crown’s edges. In this tooth implant procedure, the dental prosthetic is cemented permanently on the ceramic implant.
Two-piece ceramic implant
The latest innovation in dentistry are the two-piece ceramic dental implants. This is similar to the titanium dental implants where the tooth roots and abutment are made separately. In the two-piece systems, dentists use two methods in connecting the abutment to the implant. One method is to attach the pre-made abutment to the implant using resin cement. Another way is to connect a glass-fiber abutment to the implant using an adhesive material.
Dentistry considers ceramic implants as alternatives to patients who are allergic to metal properties like titanium. Talk to your Toronto dentist about tooth implant procedure and see if the ceramic material is most suitable for you.
