About Dental Crowns
In general, the term ‘crown’ means a full coverage restoration. The roots of your tooth remain intact as well as some tooth structure above the gumline. The finished restoration is cemented to this remaining tooth structure, encircling the tooth a full 360 degrees.
Crowns usually require two appointments. The first is to prepare the affected tooth. The degree of preparation will vary based on the extent of damage to the tooth. In some cases, materials must be added to the existing (above-gumline) in a procedure called a ‘core build up’. This ensures that the final restoration will be have the necessary surface area for full adhesion. After tooth preparation, a dental impression is made so that the restoration can be fabricated to fit the remaining tooth. This can be either an all ceramic crown or a conventional crown. Before leaving the office, the patient is fitted with a temporary crown. The crown is then fabricated by our in-house laboratory. The second appointment is then needed to cement and deliver the crown.
All Ceramic Crowns
The concept of the all-ceramic crown is not new to dentistry and has been used for a very long time. Today, a wave of technological advances to materials have yielded ceramic crowns that are far superior to their predecessors. Whether made of Zirconia or E-Max, these crowns are stronger than ever, fit more comfortably and deliver a more esthetic result.
An all-ceramic crown may not be suitable for every case. Each patient brings a specific set of needs and parameters for fit, strength and aesthetics. At Obeid Dental all of our ceramic crowns are fabricated in our state of the art, in-house laboratory by our master dental technician. With Dr. Obeid‘s expertise and the talent of our in-house dental technician, we ensure that a ceramic crown is as stunning as any other restoration that is fabricated at Obeid Dental.
An all ceramic crown is made without a metal base. This type of restoration has a long history of use in dentistry. However, because they contained only ceramic materials, these crowns could become brittle and be easily damaged. Today, there have been many advances in the materials used for an all ceramic crown, which greatly increase the strength and durability of the crown. Of these new materials, the most prevalent are Zirconia and E-Max. Zirconia crowns must be designed and milled by computer design. There are several types of Zirconia crowns, and they can vary in strength. E-Max can be conventionally made or designed and milled by computer design.
Conventional crowns are also known as ‘porcelain fused to metal crowns’. The base metal typically used is often a nickel-based alloy, which can result in an inferior product. AtObeid Dental our base metals are all High Nobel or Nobel alloys to ensure the best durability and biocompatibility for the finished crown.
There are still many indications for the porcelain fused to metal crowns and they have a long history as a dental restoration. With Dr. Obeid’s expertise and the talent of our in-house dental technician, we ensure that a conventional crown is as stunning as any other restoration that is fabricated atObeid Dental.
At Obeid Dental we take pride in delivering very customized treatment. We understand that each patient has a unique dental history and deserves individualized consideration for the best outcome.
Conventional crowns are made of porcelain fused to metal. The metal used in the crown can vary in composition, including high noble, noble and base metal (nickel). At Obeid Dental, we utilize only high noble metals for fabricating crowns. These metals are the most tested and long lasting. Larger commercial labs have trended to restorations that require less time and skill to produce. This lower quality product can be favored by dentists looking to lower costs. In the hands of a skilled technician, conventional crowns can be very aesthetically pleasing with excellent durability. Obeid Dental has an in-house lab, manned by a master technician to fabricate our conventional restorations.
