It can be challenging to choose restorations for the front teeth that provide the needed strength while maintaining aesthetic beauty. Learn more about the best crown materials for front teeth and how to select the right option.
What Are the Common Crown Materials for Front Teeth?
Choosing the best corona dental materials for front teeth can depend on a number of factors, including durability, beauty, and cost:
- One of the most common choices is crowns made of lithium disilicate (E.max). Lithium disilicate crowns are crafted from a glass ceramic that offers excellent translucency, allowing your dentist to match the shade so the restoration blends perfectly with your natural teeth. They offer moderate strength, which is enough for the front teeth. These crowns are a good choice if conservative tooth preparation is needed.
- Natural-looking crowns for front teeth also include zirconia crowns. They can be solid, meaning they are made from a single piece of material. These porcelain crowns are typically most effective for back teeth.
- Layered zirconia crowns have a strong, durable core but are covered with porcelain. They offer superior aesthetics.
- Another option you have is porcelain-fused-to-metal crowns. These restorations feature a metal structure that adds durability and a porcelain veneer that provides more predictable margins. Although they have a porcelain surface, visible metal at the gum line may still be present, which could reduce their aesthetic appeal.
- You also have the option of dental composite crowns. These are made from a resin and glass mixture. One reason they are popular is that these crowns can be made in one day using CAD/CAM technology. Alternatively, they can be made by a dental laboratory. They do tend to be less durable, however.
When deciding on dental crown materials, your dentist will consider your aesthetic demands, whether you have bite issues that could place uneven stress on the restoration, cost, and restoration lifespan, to help you make the right choice.
How Do Aesthetics and Durability Compare Across Materials?
To decide on the right dental crowns, comparing the aesthetics and durability of the various options can give you a better perspective. When it comes to translucency, lithium disilicate options offer the best results. They also have excellent shade-matching.
Layered zirconia comes next. Although these crowns don’t match the aesthetic of lithium disilicate, they can be durable. Monolithic zirconia (made from one piece) is typically stronger but offers less translucency.
You will have to decide between aesthetics and durability when choosing crowns. Here’s the breakdown of what you can expect:
- Lithium Disilicate: Great translucency, durable
- Layered Zirconia: Good translucency, requires veneering, staining, less durable
- Monolithic Zirconia: Lower translucency, stronger
- Porcelain-Fused-to-Metal: Less translucent than all-porcelain crowns, sturdier
- Composite Resin: More opaque than other options, less durable
- Oro: No translucency, durable
Another thing to consider, besides the translucency and durability of crowns, is their wear behavior against opposing teeth.
Glazed porcelain and composite resin are typically the options that cause the least damage to the enamel on opposing teeth. High-gloss zirconia and polished lithium disilicate can also offer this protection if they have a smooth surface.
Of all of the options, zirconia and gold dental crowns are the strongest and most fracture-resistant. This makes them better suited for back teeth. Composite resin, however, is easier to repair.
When Should You Choose Lithium Disilicate for Anterior Crowns?
If you need single front crowns, lithium disilicate (E.max) can be the right option. Lithium disilicate crowns are excellent for front teeth because their translucency makes them look natural. They are good choices for short-span bridges and for when you may not have sufficient enamel left for the proper bonding of any other material.
The translucency of crowns is a serious concern with front teeth. You need options that will blend in with your natural teeth. Lithium disilicate crowns can do this because they have layered staining and glazing. There are even overlay techniques that can mask discoloration. Additionally, they can be crafted rapidly using CAD/CAM techniques.
These natural-looking crowns for front teeth do have their limitations, however. Compared to zirconia or metal options, these are not as strong. They may not be appropriate for people with bruxism or who have uneven bites.
When Is Zirconia the Better Choice for Anterior Crowns?
Zirconia crowns are among the strongest options. They are better choices than porcelain-fused-to-metal crowns because there is a lower risk of chipping. For people with bruxism or a history of tooth chipping, the durability of zirconia crowns is attractive.
If you have bruxism, monolithic zirconia crowns offer additional strength. If your focus is on aesthetics, layered zirconia is the better choice because it offers translucency. There are micro-layering options that can provide the exact shade you need.
You have the option of high-translucency zirconia, too, which can help improve how well the shade matches your natural teeth.
The people who can benefit most from these crowns are those with bruxism, who need durable restorations, or who don’t have enough enamel left.
When Is Porcelain Fused to Metal Appropriate for Front Teeth?
A porcelain-fused-to-metal crown may be the right option if strength requirements outweigh translucency. This is an important option for those with severe bruxism, a very uneven bite, or compromised teeth opposing the restoration.
One important thing to know about these crowns is that they often have a visible metal edge, which can appear as a gray line along the gum line. This makes the restoration more noticeable compared to an all-ceramic crown. In some cases, the visibility can be reduced by placing the margin slightly below the gum line or using tooth-colored metal alloys.
Even porcelain fused to gold crowns need 1.5 mm to 2.00 mm of healthy vertical tooth structure above the gum line. It acts as a brace for the tooth.
These crowns also require careful tooth preparation to preserve gum health. It may not be the right choice for those with high smile lines.
Porcelain-fused-to-metal crowns are more cost-effective than other options and highly durable. The biggest drawback is visibility, although there is also a risk of chipping.
How Do Cost, Longevity, and Failure Rates Compare Between Materials?
Cost is a serious factor to consider when choosing dental crowns. There is a range of prices that depend on the materials you choose, including:
- Dental Composite Crowns: $200 to $600
- Porcelain-Fused-to-Metal Crown: $700 to $1,500
- Lithium Disilicate Crowns: $900 to $1,800
- Coronas de circonio: $800 to $2,000
- Gold Dental Crowns: $900 to $2,000
These are the costs of the implant, but there are additional fees as well. What your dentist charges may vary, and you should plan for revision expenses.
Consider the expected longevity of the different materials also. Crowns can last:
- Metal/Gold Crowns: About 15 to 25 years
- Coronas de circonio: About 10 to 20 years
- Lithium Disilicate Crowns: About eight to 15 years
- Layered Porcelain Crowns: About 10 to 15 years
- Dental Composite Crowns: About three to seven years
Crown longevity will depend greatly on whether you have an uneven bite, bruxism, or other oral health issues.
The most common problems that can occur with dental crowns and lead to a shorter lifespan are chipping or full fractures, which can cause the crown to fail. The cement can also start wearing away, leading the crown to shift or fall out. Aesthetic degradation can also be a concern, with staining and other surface wear requiring repairs.
Although crown failure due to tooth decay and infection is rarer, it can still occur. If the tooth’s structure is impacted, the crown can loosen.
Repairing or replacing a crown typically costs a good amount of money. That is why it’s usually better to invest in crowns made of more durable materials from the start. Discuss your best options, cost- and durability-wise, with your dentist.
How Should Tooth Preparation and Bonding Differ by Material?
The preparation process for a lithium disilicate crown is fast when your dentist relies on CAD/CAM technology. Your dentist will perform the necessary tooth reduction and capture a digital image of the structure. This type of crown must be bonded with resin cement, so the tooth must be etched.
For a zirconia crown, your dentist will do an occlusal reduction. They will also sandblast the internal part of the crown with aluminum oxide before bonding it with MDP-containing resin cement.
For porcelain-fused-to-metal crowns, the dentist will sandblast the structure and apply a metal primer, too. It could be MDP or one that is sulfur-based. The cement used will be a resin-modified glass ionomer or a resin cement, depending on the type of metal alloy.
Your dentist will do everything possible to preserve the maximum amount of enamel. They’ll also offer aftercare instructions to ensure you know how to increase the chances of crown success.
What Does the Evidence Show From Comparative Clinical Studies?
Clinical studies show that patient satisfaction is about the same for zirconia and lithium disilicate crowns in terms of crown longevity. At five years, zirconia crowns had a survival rate of 89.2%, while lithium disilicate crowns had a survival rate of 84.2%.
The most common complications for the lithium disilicate study subjects were chipping and fractures, while marginal discoloration was the most common problem with zirconia crowns.
Patient satisfaction was also greater with zirconia, particularly with monolithic zirconia crowns, compared with porcelain-fused-to-metal (PFM) crowns.
After 5 years, the survival rate of zirconia crowns was 98%, while that of porcelain-fused-to-metal crowns was 92%. In this study, mechanical complications were found in up to 18% of all PFM crowns but only 4% of zirconia crowns.
Anterior Crown FAQs
There are numerous types of materials to choose from for anterior crowns. Zirconia crowns tend to offer the most translucency, while fully metal crowns are visible but the strongest, which may be necessary for those with bruxism. A middle road is PFM crowns, which have a metal structure and a porcelain veneer.
Lithium disilicate crowns are excellent in terms of appearance but may not last as long as zirconia. Composite resin crowns have the shortest lifespans. Keep in mind that your hygiene habits, whether you have bruxism, dental crown maintenance, and the evenness of your bite, will all impact how long the restorations last.
The crown placement process will involve tooth preparation and bonding. The more effectively this is done, the longer your crowns can last.
1. How Soon After Whitening Can I Match a Crown?
You will need to wait at least two weeks after a whitening procedure to match your crown to your natural teeth.
2. Can Anterior Crowns Be Repaired if Chipped?
It’s possible to repair a chipped crown if the damage is minimal and only involves enamel. The crown must still fit properly. Composite resin will be used for these repairs.
Your dentist will clean the area, etch the crown, apply a primer to the porcelain or a bonding agent if there’s metal involved, and then layer the composite before polishing the crown.
3. Will Dental Insurance Cover Front Tooth Crowns?
The majority of dental plans cover a portion of the costs, with many paying up to 50% after your deductible is met. The crown must be deemed medically necessary, however. Always check your plan to ensure you know what to expect if you need a dental crown.
4. Do Crowns Cause Tooth Sensitivity Afterwards?
It’s common to experience mild tooth sensitivity after getting a crown. Biocompatibility and sensitivity go hand in hand, so some materials (like metal) can cause more issues than others. This should fade. If more than 3 weeks pass and you still experience sensitivity, or if it worsens, schedule an appointment with your dentist.
5. Can Crowns Withstand Severe Teeth Grinding (Bruxism)?
The material the crown is made of will have an impact on its lifespan if you have bruxism. Full metal options can withstand severe bruxism, but all-ceramic options can chip. The right cementation strategy can also protect the crowns.
