What Is a Monolithic Zirconia Crown?
Zirconia is a very strong ceramic used in dentistry. In a monolithic, or solid, zirconia crown the whole crown is made of the same material, with no porcelain on top. The crown is designed on a computer, milled from a zirconia block and sintered in a furnace to reach its final hardness.
Early types of zirconia were very strong but quite opaque, close to chalk white. Today more translucent types are also used. These look more natural, but give up some of their strength in return. Which type is chosen depends on where the tooth is.
Systematic reviews of tooth-supported monolithic zirconia restorations report a high rate of problem-free use and low fracture rates in the short and medium term. Long-term data for the newer types of zirconia are still building up.
The surface of zirconia cannot be roughened with acid. So before the crown is fixed to the tooth, its inside is air-abraded and a special primer is applied. Correct surface preparation helps the crown stay in place for a long time.
Material
Solid zirconium oxide ceramic, with no porcelain layer on top.
Strength
High resistance to fracture, suitable for molars and bridges.
Appearance
Tooth-coloured; classic types are more opaque, newer translucent types look more natural.
Bonding
The inside is air-abraded, a special primer is applied and the crown is usually fixed with resin cement.
Care
Its polished surface is less prone to holding plaque and wearing the opposing tooth.
Who Might a Monolithic Zirconia Crown Suit?
A monolithic zirconia crown is considered when strength matters but a metal look is not wanted. The decision depends on where the tooth is and the forces of your bite.
Molars
On the back teeth, where chewing forces are highest, it offers a strong, tooth-coloured option.
People who clench or grind
With no porcelain layer, there is no porcelain to chip. A night guard is still discussed for these patients.
Bridges
For bridges replacing one or more missing teeth, it can span longer gaps than glass-ceramics.
Darkened teeth or teeth with metal posts
Its more opaque structure helps hide a dark colour or metal underneath.
Tooth position and aesthetic expectations
On front teeth, translucent types of zirconia or glass-ceramic options may be considered. On back teeth, high-strength types are preferred.
Crown thickness
Zirconia can be made thin, but it still needs a certain thickness. How much space is made on the tooth is planned at the examination.
Bite
Contacts with the opposing teeth and any grinding habit are assessed. Bite adjustment is added to the plan if needed.
Front teeth with very high aesthetic expectations
On front teeth where the most natural translucency is expected, lithium disilicate or layered options may be more suitable.
Untreated decay or gum disease
Decay, gum inflammation or an infection at the root tip should be treated before the crown.
Possible Risks and Limits of a Monolithic Zirconia Crown
Fracture is uncommon with monolithic zirconia. The risks are mostly linked to bonding, the bite and the tooth itself.
Loosening
If the surface preparation and bonding are not done correctly, the crown can loosen over time.
Wear on the opposing tooth
A zirconia surface left rough can wear the opposing tooth. This is why adjusted surfaces are polished.
Appearance
Classic types of zirconia can look more opaque than the neighbouring teeth on front teeth.
Temporary sensitivity
There may be brief sensitivity after the tooth is prepared and the crown is fitted.
Permanent tooth loss and decay under the crown
The tooth is reduced for the crown and this cannot be undone. If cleaning is not thorough, the tooth under the crown can decay at the edge.
How Is a Monolithic Zirconia Crown Made?
A monolithic zirconia crown is designed and milled digitally. The process is usually completed in two appointments.
- 1
Examination and planning
Your dentist checks the condition and colour of the tooth, any old fillings, your gums and your bite, and takes X-rays if needed. Any treatment needed first is planned beforehand.
- 2
Preparing the tooth
Under local anaesthetic, the tooth is reduced to the thickness zirconia needs. This is often less than for a porcelain-fused-to-metal crown.
- 3
Digital scan or impression
The prepared tooth is scanned or an impression is taken. A temporary crown is fitted while the crown is being made.
- 4
Design, milling and sintering
The crown is designed on a computer, milled from a zirconia block and sintered in a furnace. During sintering it shrinks to its final size and hardness, and is then coloured and polished.
- 5
Try-in and bite check
Your dentist checks the fit, the edges, the contacts with the neighbouring teeth and your bite. Any adjusted surfaces are polished again.
- 6
Bonding the crown
The inside of the crown is lightly air-abraded with aluminium oxide powder and cleaned. A special primer containing MDP is then applied. The crown is usually fixed with resin cement or self-adhesive resin cement. If the shape of the tooth gives enough retention, resin-modified glass ionomer cement can also be used.
Alternatives to a Monolithic Zirconia Crown
Depending on where the tooth is and what you expect from its appearance, these options can also be considered.
Layered zirconia crown
A zirconia core covered with porcelain; it looks more natural, but the porcelain layer can chip.
Lithium disilicate crown
A glass-ceramic that lets light through more naturally; often chosen for front teeth and premolars.
Full metal crown
A strong option that needs the least tooth removed, but it is metal-coloured.
Porcelain-fused-to-metal crown
An option with a long clinical record; a metal shadow can show at the gum line.
Materials and Bonding in Monolithic Zirconia Crowns
Because zirconia contains no glass, it cannot be etched with hydrofluoric acid like lithium disilicate. Instead, the inside of the crown is air-abraded at low pressure with aluminium oxide powder. This cleans the surface and creates a slight roughness for bonding.
A phosphate-based primer called MDP forms a chemical bond with the zirconia surface, and the resin cement grips the crown through this primer. Because saliva can weaken this bond, the inside of the crown is cleaned again before bonding if it has touched saliva during the try-in.
Polishing any areas adjusted for the bite is especially important with zirconia. A polished zirconia surface causes less wear on the opposing tooth, while a rough surface can increase wear and make plaque build-up easier.
Computer-aided design and milling
The crown is designed digitally and milled precisely from a zirconia block.
Sintering
Firing in a furnace brings the crown to its final size and hardness.
Air abrasion and MDP primer
The inside is air-abraded and coated with a phosphate-based primer to prepare it for bonding.
Polishing
Polishing adjusted surfaces helps reduce wear on the opposing tooth and plaque build-up.
Settling In and Caring for a Monolithic Zirconia Crown
You can use the crown on the day it is fitted. Most people get used to it within a few days.
- 1
The first few hours
Avoid eating and hot drinks until the numbness wears off.
- 2
The first few days
There may be brief sensitivity to hot and cold, which usually settles on its own.
- 3
The first few weeks
If the crown feels high when you bite, go back for a check. Because zirconia is very hard, a high spot can strain the opposing tooth and the jaw joint.
- 4
Long term
At regular check-ups your dentist looks at the crown edge, your gums, your bite and any wear on the opposing teeth.
Daily cleaning
Brush the crown twice a day and clean where the crown meets the gum and between the teeth with floss or an interdental brush.
Night guard
If you grind your teeth, wear the night guard your dentist recommends. It protects both the opposing teeth and the crown.
Regular check-ups
Decay at the crown edge or gum recession is easier to deal with when spotted early.
Pain or a high spot when biting
If biting still hurts or the crown still feels high after a few days, it needs checking.
The crown is loose or comes off
If the crown moves or comes off, keep it and contact the clinic. Do not try to glue it back yourself.
Lasting gum redness
If the gum around the crown keeps bleeding or stays swollen, it needs assessment.
What Affects the Cost of a Monolithic Zirconia Crown
The cost depends on the number of crowns or bridge units, the type of zirconia and any treatment needed first. You will get exact information with your treatment plan after the examination.
Number of crowns and bridge units
A single crown and a bridge covering several teeth need different design and milling work.
Type of zirconia
Classic high-strength types and translucent types are used for different purposes.
Treatment needed first
Decay treatment, a filling, root canal treatment or gum treatment are added to the plan if needed.
Your bite
If you grind your teeth or your bite needs correcting, a night guard or bite adjustment may be added to the plan.
Appointment plan
For patients coming from abroad, milling and sintering time is planned together with the length of your stay in Antalya.
Before / After
Frequently Asked Questions About Monolithic Zirconia Crowns
What is the difference between a monolithic and a standard zirconia crown?
In a monolithic zirconia crown, the whole crown is zirconia. In a layered zirconia crown, porcelain is added on top of a zirconia core. The monolithic version is stronger; the layered version can look more natural on front teeth.
Can zirconia crowns be used on front teeth?
Yes. On front teeth, more translucent types of zirconia or layered zirconia are preferred. Where the most natural look is expected, lithium disilicate can also be considered.
How is a monolithic zirconia crown bonded to the tooth?
The inside of the crown is air-abraded with aluminium oxide powder, cleaned and coated with a primer containing MDP. The crown is usually fixed with resin cement or self-adhesive resin cement. Where suitable, resin-modified glass ionomer cement can also be used.
Does zirconia wear down the opposing tooth?
A polished zirconia surface causes less wear on the opposing tooth than many other ceramics. Wear can increase if the surface is left rough, so adjusted surfaces are always polished.
Can a zirconia crown break?
Fracture is uncommon with monolithic zirconia. Rarely, cracks can appear in crowns made very thin or under excessive force.
Does the colour of a zirconia crown change?
The zirconia surface does not change colour. Over time, the cement at the edge or the natural teeth around it may change colour.
How many days do I need to stay in Antalya?
A single crown or a short bridge is usually completed in two appointments, with a few days in between for milling and sintering. The exact time is confirmed after the examination.
