Partial vs Full Coverage Crowns
There are a number of dental restorations that can be used to restore a tooth that has been compromised from decay or other damage or trauma. The type of restoration that your dentist decides to use will largely depend on the extent of the damage. Dental crowns are one of the most common restorations and come in the form of either a partial crown or a full coverage crown.
The process for both a partial crown and a full coverage crown is the same, the only difference being how much of the tooth is covered. The amount of tooth structure that is lost with a partial crown is less than that which is lost for a full crown because the restoration itself is smaller. Therefore, less tooth structure has to be removed to allow the restoration to fit.
Do I need a partial or full coverage crown?
One of the biggest contributing factors when determining if your tooth needs a full or partial crown is the extent of damage to the tooth. It is ideal to use a partial crown when possible, but if damage is too severe and a significant amount of tooth structure will be lost during the removal of decay, a full coverage crown is going to be your best bet. Fractures that extend over a significant portion of the tooth will also benefit from a full coverage crown. Some other factors that can have an impact on whether you need a full or partial crown include location of the tooth, aesthetics, and even durability of the restoration.
Location: The main function for the tooth being restored is an important consideration. Teeth that take on a lot of chewing or bite force will do better with a full coverage crown. Additionally, teeth that are part of a supporting structure like a dental bridge, 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 as with front teeth, since they still provide reinforcement while preserving tooth structure.
Aesthetics: Anterior teeth that show when you smile need to have cosmetic results considered. While a full crown can be placed on any tooth, advancements in dental technology make it possible to have a partial crown that covers only the front of the tooth, like a veneer, which can provide a better aesthetic outcome.
Durability: Both types of crowns are incredibly strong though full crowns have greater durability since they encase the entire tooth. Full coverage crowns are ideal for teeth that have more significant damage or are fractured. A cracked tooth may be saved with a full coverage crown, allowing the patient to keep their natural tooth longer. Partial crowns are better suited to teeth with minor damage.
Your dentist will determine what type of crown is appropriate to restore your damaged tooth. Though a partial crown is a little less invasive, they are not always the best choice.
