治疗内容、费用与周期
- 患者概况
- Female, 40s
- 诊断
- Multiple missing teeth in the upper arch with periodontal disease, failing existing prostheses, and several carious teeth. Chief complaints: difficulty chewing and aesthetic concerns.
- 治疗内容
- Two three-unit monolithic zirconia bridges in the upper arch, one aesthetic partial denture replacing the remaining missing teeth, and caries treatment on the affected teeth. Sequenced to stabilise the periodontal condition before final prosthetics were delivered.
- 使用材料
- Monolithic zirconia (bridges) + thermoplastic resin / cobalt-chromium framework (partial denture)
- 治疗周期
- Approx. 4 months
- 就诊次数
- 7 visits
- 费用
- Self-pay total ¥1,179,600 (incl. tax). Breakdown: ¥499,900 × 2 three-unit zirconia bridges + ¥179,900 aesthetic partial denture + caries treatment and consultation.
主要风险与副作用
- Periodontal disease must be stabilised and maintained long-term; progression can affect both bridges and the partial denture, with risk of additional tooth loss
- Abutment teeth must be prepared (irreversible enamel reduction) to seat the bridges
- Bone resorption at edentulous sites continues over time and cannot be fully prevented with bridges or removable dentures
- Risk of debonding or fracture of the zirconia bridges over time, especially under heavy bite forces
- Cleaning under the pontic and around the partial denture clasps requires tools such as floss threaders and interdental brushes
- The partial denture must be removed and cleaned daily; periodic adjustments are typically needed to maintain fit
- If an abutment tooth fails, the corresponding bridge may need to be remade in full
- Untreated periodontal disease, poor oral hygiene, or bruxism can shorten the lifespan of all restorations

Single-layered vs multi-layered zirconia — how the material is chosen
Not all zirconia is the same
Zirconia is a tooth-coloured ceramic prized in dentistry for being exceptionally strong while still metal-free. But 'a zirconia crown' is not one single thing: the two everyday options — single-layered (monolithic) and multi-layered — differ in how their colour is structured, and that changes where each one belongs in the mouth.
The headline difference patients notice is price: ¥179,900 versus ¥229,900 per crown at RODIN (incl. tax). The more important difference is what that buys — strength on one hand, a natural-looking shade gradient on the other.
As a general rule we match the material to the tooth's job: strength where chewing forces are greatest, aesthetics where the smile shows most.
Single-layered (monolithic) zirconia
Single-layered, or monolithic, zirconia is milled from one uniform shade of high-strength zirconia. Its even, homogeneous composition gives it the highest strength of the zirconia options, which makes it very well suited to back teeth (molars and premolars), where chewing forces are greatest and a fracture would be most costly.
Because it is milled from a single block with no built-in colour transition, it is also the more cost-efficient choice — ¥179,900 per crown at RODIN (incl. tax). For a molar that is barely visible when you smile, its uniform shade is rarely a drawback.
- Strength: highest of the zirconia options
- Best for: molars and premolars (back teeth)
- Fee at RODIN: ¥179,900 per crown (incl. tax)
Multi-layered zirconia
Multi-layered zirconia is manufactured with a built-in colour gradient — more chromatic and opaque toward the gum (the dentine zone) and progressively more translucent toward the incisal (biting) edge — mimicking the natural transition you see in a real tooth.
That gradient is why it is the usual choice for front teeth (the anterior, aesthetic zone), where blending seamlessly with the neighbouring natural teeth matters most. A single-shade crown can look slightly flat next to natural teeth; the layered gradient avoids that.
The more involved material carries a higher fee — ¥229,900 per crown at RODIN (incl. tax). It is still a high-strength zirconia restoration; the extra cost reflects the gradient and its aesthetic role, not a weaker or 'cheaper' core.
- Aesthetics: built-in shade gradient mimics a natural tooth
- Best for: front teeth (the visible, aesthetic zone)
- Fee at RODIN: ¥229,900 per crown (incl. tax)
How RODIN chooses — and the price difference
As a general rule we use multi-layered zirconia for front teeth (where aesthetics lead) and single-layered/monolithic zirconia for back teeth (where strength leads). For a patient who clenches or grinds heavily, the balance may tip further toward the stronger monolithic option even slightly further forward. The final choice is made for your case and confirmed in writing.
The roughly ¥50,000-per-crown difference reflects the more involved, gradient material and its aesthetic role — not a difference in overall 'quality' or durability. Both are high-strength zirconia restorations made to the same standard of fit and finish.
Zirconia or an e.max crown?
Zirconia is not the only ceramic for a crown. For some single front teeth, an IPS e.max (lithium disilicate) crown can give an exceptionally lifelike result thanks to its translucency. Zirconia, in turn, offers higher strength and is the safer choice under heavy load or for longer-span bridges.
So the conversation is sometimes not just 'which zirconia' but 'zirconia or e.max' — and, as with veneers, the right answer is case-specific and confirmed at planning.
Prices include tax. Material selection is individualised; individual results vary.
常见问题
Front or back teeth — which zirconia do I need?
As a general rule, multi-layered for front teeth (aesthetics lead) and single-layered/monolithic for back teeth (strength leads). Heavy grinding can shift the balance toward the stronger option. The choice is confirmed for your case.
Why is multi-layered zirconia more expensive?
The built-in shade gradient is a more involved material (¥229,900 vs ¥179,900 for single-layered). It reflects the aesthetic role, not a difference in overall quality — both are high-strength zirconia.
Do zirconia crowns look natural?
Modern zirconia — especially multi-layered in the front — can look very natural. A single uniform shade can look slightly flat next to natural teeth, which is exactly why the layered gradient is preferred in the aesthetic zone.
Zirconia or an e.max crown?
e.max (lithium disilicate) is highly aesthetic for some single anterior crowns; zirconia offers higher strength and suits heavy load and bridges. The right choice is case-specific and confirmed at planning.
Will a zirconia crown wear down my opposing teeth?
Well-finished, polished modern zirconia is designed to be kind to the opposing teeth. A smooth, properly adjusted biting surface is part of how the crown is made and fitted.
How long do zirconia crowns last?
Zirconia is among the most durable crown materials. Longevity varies with bite, hygiene, and the health of the underlying tooth; with good care these restorations are made to last many years.
