Fixed Partial Prosthesis-Treatment Options

The dental crowns cover or wrap the visible part of the tooth to give it its original shape and position. Thus, it takes over all the main functions of a tooth.

As a patient, we must not forget that the achievement of perfect results, of a beautiful and  functional dentition are closely related to the experience and professionalism of dentists specialized in various fields: prosthetics, periodontologists, endodontics, surgeons, orthodontists.

Specialists in EXCEDENT clinic have 20 years of solid experience in dental medical practice, dedication and enthusiasm.

We have been collaborating for 20 years with the largest dental laboratory in the country. The physician-technician team is welded together for 20 years together, each learned from the professional secrets of the other so that in the end the patient receives exactly what he wants.

 

The main functions of a dental crown are:

 

  • Aesthetics: to be similar in shape, size and color to neighboring teeth, or match facial aesthetics and patient wishes in case of complete oral rehabilitation.
  • The masticatory function: the crown must be accurately modeled so that the mastication process is properly carried out without any intervention with the automatic movements of the mandible.
  • The phonetic function: the dental crown must provide a support for the tongue in the diction and not make it difficult to speak when the crown is used in the lateral zone.
  • Increasing tooth resistance: the dental crown should conserve and increase tooth strength.

 

In one of our previous articles I answered the most common questions about dental crowns (link to the previous article).

Thus, in this article we intend to detail the types of dental crowns existing on the market because it is important to let you know about this subject and its handy to have access to quality information.

 

Thus, there are the following types of dental crowns:

All-metal dental crown: metals that are used in these dental prosthesis typically contain gold alloys, palladium alloys or base alloys (chromium nickel or cobalt-chromium). Compared to other types of dental crowns, metal-based crowns requires removal of smaller amount of tooth structure for the intervention to succeed. Dental metal crowns are the most durable and resistant, do not break and resist high masticatory forces. Their disadvantage is the metallic color, unsuitable for the teeth seen when you smile.

 

Porcelain fused to metal (chrome – cobalt base) crowns:

this type of crown can render any color of teeth, and can be used for visible front teeth. Porcelain fused to metal crowns are recommended in both the posterior and front areas, ensuring an optimal balance between resilience and aesthetics at an attractive price. They are the most commonly applied crowns (80%), the technology of which has been continuously improved for over 60 years.

 

Acrylic Dental Crowns:

 

This type of dental crown is one of the cheapest and quickest to fabricate. Their disadvantage is that they have a low lifetime (3 months). At the same time, they present a fairly high risk of fracture than those of porcelain combined with metal. They are made very quickly and are used in particular as temporary dentures.

 

All ceramic crowns:

 

these dental crowns, when done by an experienced technician,can reproduce perfectly the color and shape of natural teeth. The disadvantage this dental crown poses is low strength. However, dental ceramics crowns are completely chosen for visible frontal teeth in patients with special aesthetic requirements. Ceramic dental crowns are the most expensive because they use a special type of ceramics that provides a beautiful aesthetics without any substructure (metallic or zirconium), being made using the refractory model technique.

 

Zirconium crowns:

 

Zirconium is a material that has been developed 20 years ago and is viewed by dentists as the most resistant material. Zirconium can be used for different purposes, however, for the manufacure of zirconium dental crowns it is necessary to have CAD-CAM systems. Zirconium is a white-yellow ceramic material. In dentistry, pure zirconium is not used, but zirconium oxide.

 

Zirconium has several properties:

 

  • White color ensures zirconium dental crowns a very beautiful aesthetics.
  • The computerized systems for processing the substructure of these dental crowns provide very good accuracy.
  • The significant cost of production due to the modern processing technology and new multilayer blocks that provide superior quality and aesthetics at a higher price than metal-ceramic dental crowns.

 

Zirconium can be used for:

 

  • The substructure of ceramic dental crowns.
  • Fixed dental prostheses (crowns and dental bridges up to 3 elements) made of zirconium – BRUXZIR.
  • Titanium based zirconium-personalized abutments for dental implants of any type.
  • Zirconium post and cores for visible teeth.

 

Ceramic dental crowns with gold alloy substructure:

 

A major disadvantage of this type of dental crown is its high price: they are the most expensive dental crowns because the golden alloy required is more expensive than the zirconium substructure.

 

Composite fused to metal crowns:

 

these crowns have a lifetime of 3-5 years, but a lower resistance than dental ceramics or zirconium dental crowns. because the composite is softer and faster to wear, which leads to the migration of both the antagonist teeth and the abutment teeth. It is not recommended for chewing areas.

 

PMMA Dental Crowns:

 

They are made by computerized systems and are povisional crowns for smile design. They can be used for 3-6 months and are made very quickly (1-2 days).

 

Ceramic dental crowns on E-MAX substructure:

 

the best combination of aesthetics and strength, the precision of the adaptation on the tooth being maximum. These crowns are bonded to teeth and made with CAD-CAM computerized technology! Their cost is higher than those of zirconium, but the quality is superior.

Because of the translucency of the emax they are not indicated for the covering of metallic post and cores or teeth with severely modified color.

 

Of all these types of dental crowns, the most used are those zirconium dental crowns. These are preferred by most patients because the material used is sufficiently resistant. for a long life of the dental crown.

 

EXCEDENT Clinic specialists use only top quality materials for conservative treatments as well as for dental prosthesis and implantology.

Using advanced techniques, we can provide our patients guarantees for prosthetic and conservative treatments performed in the clinic.
