Dental implants are used as a replacement for lost tooth due to tooth decay, old age or hereditary reasons. Mini dental implants are the new advancement in the field of cosmetic dentistry which are nothing but a smaller version of dental implants. Here we will discuss dental crowns which are a commonly used dental implant to connive a missing tooth. These implants consist of two parts, the first being a base or root which is anchored to the jaw bone and the second part is called a crown which is in shape of a tooth. The root or base is made of Titanium and the crown is made of ceramic.
Why is titanium used for dental implants? : The first part of the dental implant that is anchored in the jaw bone is made up of titanium and in shape of a screw. Titanium is a light weight metal which is inert and hence will not react with any chemical. The beneficial fact about this metal is that it combines easily with the real bone. This process of integration of the implant that is artificial and bears a load, with the natural bone is known as osseointegration. What makes it an apt choice is that it has tremendous capacity to bond well with the natural bone and form a connection that can be relied upon. Owing to the fact that this metal does not consist of animate tissues or particles, they will be accepted in the body without the risk of rejection by the body. It also has the quality of being a metal that is compatible with oral tissues and bones. It’s availability in the market is in four varities that can be differentiated on the basis of their iron and carbon concentration. But the recent times have witnessed grade five titanium also being used for this purpose. An advantageous fact about this variety of titanium is that they are stronger and more fracture resistant than the other types. The above mentioned property is distinctive in titanium and hydroxylapatite and these materials have helped the medical science advance and progress and have been of many uses like in dental implants and joint replacement techniques.
The process: The process of fixing this implant is done in two parts. In the first part, the titanium piece or root is anchored into the jaw bone. Then comes the phase where it is allowed to heal and combine with the real bone and the bone is allowed to grow over the titanium root. Titanium plays the role of a good base for the ceramic crown which is in shape of a tooth and looks exactly like the other teeth in the array. During the period when the titanium root is left to heal the dentist will fix a temporary crown over it for stability and a new and permanent crown will be placed once the root gains stability.
Mini dental implants are made of titanium alloy. They are a combination of midget titanium rod with a retaining fixture that holds a rubber ring that behaves like a socket.
