The tooth crown: great tooth treatment solution
It's nice to have you here on site Dental Care Clinic!
A tooth crown is a cap-like tooth restoration used to cover a damaged tooth. The tooth crown can give support to misshapen or badly broken teeth and permanently replace missing teeth to complete a smile or improve a bite pattern.
The tooth crown may be molded from metal, ceramic, plastics, or combinations of all three. They are cemented in place and coated to make them more natural looking.
Historically, a variety of materials have been used as tooth replacements. The ancient Egyptians used animal teeth and pieces of bone as primitive replacement materials. More recently, artificial teeth have been fabricated from substances such as ivory, porcelain, and even platinum.
With modern technology, high quality tooth replacements can be made from synthetic plastic resins, ceramic composites, and lightweight metal alloys.
The materials of tooth crown must be suitable for use in the oral cavity, which means they must be acceptable for long term contact with oral tissues and fluids.
Metal as material for tooth crown is preferred for strength but acrylic resins and porcelain have a more natural appearance. Therefore the selection of crown material is, in part, dependent on the location of the tooth being covered.
Plaster molds in crown's construction are made from a mixture of water and gypsum powder. Used for dental applications since the 1700s, gypsum is finely divided calcium sulfate dihydate.
Depending on application different types of plasters are used: impression plaster is used to record the shape of the teeth, model plaster is used to make durable models of the oral cavity, and investment plaster is used to make molds for shaping metal, ceramics and plastics. Waxes are also sometimes used in this regard.
Common alloys used in tooth crown are based on mixtures of mercury with silver, chromium, titanium, and gold. These mixtures form a blend than can be easily shaped and molded, but which hardens in a few minutes.
Ceramics are well suited for use in tooth crown because they have good tissue compatibility, strength, durability and inertness. They can also be made to mimic the appearance of real teeth fairly closely. However, the tensile strength of ceramic is low enough to make it susceptible to stress cracking, especially in the presence of water.
Ceramic is most often used as a coating for metal-structured tooth crown. The two primary types of ceramics used in tooth crown: made from potassium feldspar and glass-ceramic.
The first resin used in denture materials was vulcanized rubber in 1839. Since then, a number of other resins have been developed which are more suitable for dental applications. Today, acrylic polymer resins are commonly used in dentures and crowns.
Special dental adhesives, or dental cements, are used to hold the tooth crown in place. Dental adhesives can be classified as either aqueous or nonaqueous. The aqueous type include zinc phosphates, polycarboxylate cements, glassionomer cements, and calcium phosphate cements. The nonaqueous type include zinc oxide-eugenol, calcium chelates, and acrylic resins such as polymethyl methyacrylate.
Coatings are used to make the tooth crown appear more natural. Porcelain is used in this regard, but it is difficult to work with and hard to match to the tooth's natural color. Resins similar to the ones used in tooth construction are also used to create tooth-colored veneers on crowns. These resins have an advantage over other veneers in that they are inexpensive, easy to fabricate, and can be matched to the color of tooth structure. However, acrylic coatings may not adhere to the crown's surface as well as porcelain or other materials.
The process of installation of tooth crown begin after the each crown has been successfully completed and created into prepared area. The prosethedontist applies cement to the inside of the crown surface and then fits it into place over the tooth. Because of the number of processing steps there may be a slight discrepancy in the fit and the crown may require minor grinding and smoothing of its surface to ensure it fits correctly.
Good quality control is critical to ensure the tooth crown fits and looks natural in the patient's mouth. Every crown is unique because every person's mouth is different and every crown is custom molded to fit.
Dental technology is constantly advancing and these improvements are already finding application in tooth crown manufacturing. State of the art tooth crown can be made with an industrially produced core made of densesintered ceramic, and an outer layer of porcelain is added by hand.
This futuristic crown material is made by an advanced Computer Aided Design (CAD) process, known as Procera process, which was introduced in the mid-1990s in Switzerland. This process results in tooth crown with improved strength and optimal fit. Unlike other crown materials, tooth crown made by the Procera process can be used anywhere in the mouth due to the strength of its core material and its more natural appearance.
Another advance in tooth crown technology involves pre-made and pre-sized stainless steel crowns, which are designed as generic tooth replacements. Usage of this new type of crown is very simple: first the tooth surface is prepared then the selected crown is cemented in place with a standard stainless steel crown adhesive. The crown can be crimped or cut to fit and the epoxy finish will not chip or peel. While this new technology offers increased simplicity, it does not give the same appearance as a custom made crown.
