The front teeth are considered to be incisors and canines of lower and upper jaws. We at first analyze features of its purpose and structure. The incisors are the teeth situated in the middle, that is why they are called front teeth. Apart from a root, they have a crown and a cutting edge. Their main function is to nibble food. They are not able to withstand greater chewing pressure and are the most vulnerable to various factors of mechanical impact.
Canines are the four teeth situated at the corners of dental arches. The primary function of the canines is the separation of more dense and solid pieces of food if greater force is required and the cutters cannot do all the work. They are more durable than cutters. In order to restore chewing element that is partially or completely lost its functional ability and altered the structure, use different types of prosthetics. One of these is the installation of crowns – fixed bridge on front teeth.
Indications for Prosthetics of Front Teeth
The restoration of the front teeth is considered to be the most popular because they are in the smile zone. Crowns on front teeth are used in cases of dental caries and traumatic injuries to the front teeth, especially in the inflammatory process of the pulp. They are also used in excessive abrasion of chewing.
During necrotic processes in the pulp, the enamel color can change dramatically. In this case, there is a need to put crowns or bridge on front teeth. A single crown on a front tooth can be fixed either on the preserved root or engraftment in the implant. If you need to restore one or two of the front segment, use can make use of a bridge, which is the construction of interconnected crowns.
Types of Crowns for Front Teeth
There are many materials that are used for crowns, which are installed on a front tooth (bridge belongs here too). We will discuss the most popular and practical options that benefit patients around the world.
This type has metal base whose thickness is about 0.5 mm. As a rule, it is produced by alloy of cobalt and chromium, however, often it is based on gold. In the laboratory layers of ceramics are applied on a metal frame, which is calcined at high temperatures to achieve integrity and strength of construction. Metal-ceramics has good reviews from users, and has the absolute advantages: good aesthetics, low price and reliability.
Ceramics is designed specifically for aesthetic prosthetics. Because of its relative brittleness, they are almost not applied in the chewing area, in addition, with the ceramics only a single prosthesis is possible, not a bridge. Crowns on front teeth of pure ceramics have its drawbacks: the relative fragility of the products and high cost. It is for the first reason they are not recommended to put on the premolars and molars, as they may not withstand heavy chewing pressure. Such prostheses are not capable of causing an allergic reaction. Many patients choose porcelain bridge on front teeth. The choice in favor of one or another technique has undeniable importance as pressed ceramic crowns on front teeth are far more durable than their counterparts due to decrease of the risk of chipping and increase the longevity of life.
How Is It Installed?
Installing of crowns and bridges takes place in several stages: scanning the affected area, the formation of the mold based on the obtained data, sending it to the dental laboratory for fabrication of crowns. Next, the dentist conducts preparatory activities in order to avoid the possibility of occurrence of inflammatory processes in this location. Then a temporary plastic crown is installed. After manufactured orthodontic element is ready, it is attached to a native tooth.
