Crowns

Crowns & Bridges : A crown is a tooth shaped restoration that is made outside your mouth, it is fitted over your own tooth and is held permanently in position by specialised dental cements. A crown is usually required when a tooth has cracked, this will most commonly occur when the tooth has been weakened by a previous large filling. As fillings get larger the amount of tooth substance remaining reduces to a point where the remaining tooth is too weak to hold a filling in place and either the filling falls out or some of the tooth breaks away from the side of the filling. In this situation a crown is made to fit down over your tooth to replace the previously lost tooth structure and hold the remaining tooth together.

Crowns can be made from a number of materials. Most commonly they are made from a ceramic, metal or a combination of metal and ceramic. Ceramic crowns are by far the most aesthetic. In the past ceramic crown were sometimes not strong enough to withstand the force of chewing and in these situations either metal or a metal ceramic crown could be used. However advances in material science has resulted in the development of new strong yet beautiful ceramic crowns which mean that we rarely have to resort to metal or metal ceramic crowns anymore.

Traditionally crowns were made over at least 2 appointments. At the first appointment the tooth was prepared, an impression was taken and a temporary tooth was made. The impression was sent to a laboratory where over the course of a couple weeks the crown was made. It was then sent back to the dentist who fitted the crown to the patient’s tooth.

We are delighted that we are able to provide crowns, bridges, veneers or implant retained crowns in one trip to our practice. We can do this because of our on-site dental laboratory and because of our investment in the latest CAD-CAM technology. We have the newest Sirona omnicam intraoral scanner and at the time of writing are using the latest 4.4 Cerec software, we continually upgrade our software and technology to ensure our patients receive the most up to date treatment possible.

Advantages of one visit Crowns

  • Convenience of completing the treatment in one trip
  • Patients don’t need multiple anaesthetics
  • Patients don’t have to wear temporary crowns. These never look or fit as well as the final crowns. They can on occasion be troublesome as they can be prone to fracture or coming out unexpectedly.
  • Very often providing one visit crowns allows us to provide either 3/4 crowns or onlays instead of full coverage crowns. This allows us to save more of the patient’s own tooth and therefore provide a stronger tooth crown complex maximizing the long-term success for our patients.
  • Freshly prepared tooth has a stronger bond strength than tooth prepared a couple weeks previously, therefore less tooth needs to be removed to hold the crown firmly in place.
Crowns & Bridges

Bridges

Crowns & Bridges from Abbeytrinity Dental Practice TuamCrowns & Bridges : Before the development of dental implants a bridge was the only fixed replacement for a missing tooth. A removable denture can also be used to replace a missing tooth but these have a number of disadvantages including reduced patient comfort and long term damage to the remaining teeth and gums due to oral hygiene difficulties.

A bridge uses the neighboring teeth to hold the replacement tooth fixed in position. There are 2 main types of bridges, Conventional or Maryland bridges.

A Conventional bridge is fitting over the neighboring tooth or teeth. It has the disadvantage that a significant amount of the neighboring teeth needs to be filed away to make this type of bridge. It has the advantage of being more secure than a Maryland bridge.

Maryland bridges are glued to the neighboring teeth. They have the advantage of being less destructive in the short term than conventional bridges. However, they are not as securely attached to the neighboring teeth and can on occasion come out without warning.

Statistically bridges give more trouble in the long term than dental implants, all things being equal a dental implant is a better tooth replacement solution than a bridge. However, there are still cases where a bridge may be the best solution, for example, where there is insufficient bone for ideal implant placement, if the neighboring teeth have been weakened in the past by large fillings and require a crown to reinforce them anyway, or in the case of a very young person who has not finished growing.

Traditionally bridges were made over at least 2 appointments. At the first appointment the neighboring teeth were prepared, an impression was taken and a temporary tooth replacement was provided. The impression was sent to a laboratory where over the course of a couple weeks the bridge was made. It was then sent back to the dentist who fitted the bridge.
