Dental crowns are used to restore a compromised tooth and depending on the extent of the damage, your dentist may choose between a partial crown and a full coverage crown. Aside from extensive damage, there are other factors that your dentist will consider when determining what type of crown will best suit you but the degree to which the tooth is compromised will be the deciding factor. Let's take a closer look at determining factors for partial and full coverage crowns.
Tooth Structure
Since a partial crown does not cover the entire tooth, they are a more conservative option which helps preserve natural tooth structure. When a full crown is used, the entire surface of the tooth has to be filed down a bit to allow room for the new crown. Patients with minor decay may be able to have a partial crown placed, saving as much natural tooth structure as possible.
Location
The main function for the tooth being restored is also to be considered. If the tooth and your significant chewing or bite force, or is part of a supporting structure for a neighboring tooth, a full crown may be the better option for the strength and durability it offers. A partial crown is generally better suited for teeth that only undergo moderate chewing or bite forces since they offer sufficient reinforcement while still preserving tooth structure.
Durability
Both partial and full dental crowns are incredibly strong though full crowns tend to have greater strength and durability since day in case the entire truth. Full coverage crowns are ideal for teeth that have more damage or are fractured. A cracked tooth may be saved with a full coverage crown, allowing the patient to keep their natural tooth longer and avoiding extraction. Partial crowns are ideal for teeth with only moderate damage since they allow for more tooth preservation while still providing the strength needed to support a compromised tooth.
Aesthetics
If a tooth that shows when you smile it needs to be repaired, the cosmetic results are as important as anything. A full crown can be used however advancements in dental technology have made it so that it is possible to have a partial crown that works like a veneer, covering only the front of the tooth and blending in with the patient's smile.
Extent of Damage
We have come to the biggest factor when deciding between a full coverage crown and a partial crown. If it is possible, a partial crown is ideal but if damage is too severe and a significant amount of tooth structure will be removed, a full coverage crown is the way to go. This may be the case with tooth fractures, extensive decay, or large old fillings that need to be replaced.
As with any dental treatment, it is important to understand the cost associated with the restoration. Your dentist will be able to provide a treatment plan with a detail of the cost of treatment so that you can take your budget considerations into account. Full coverage crowns are sometimes more expensive than partial crowns since they use more material and the procedure is a little more involved. It is important to follow your dentist's advice to make sure you have a dental restoration that will last and be a good investment in your healthy smile!
