Zirconia has become the most widely used crown material in modern dentistry, but most patients encounter the word on a price list without understanding what it actually means for their tooth. Knowing what zirconia is, where it performs best, and where another material might serve better is the difference between choosing a crown that lasts and one that does not.
This guide covers the material science behind zirconia crowns, how the clinical evidence compares across materials, and what patients getting zirconia crowns in Vietnam should know before they book.
What zirconia crowns actually is and why it became the dominant crown material
Zirconia is a ceramic material, not a metal, despite being described as having metal-like strength. The full name is yttria-stabilized zirconia, a crystal structure that gives it a flexural strength of around 1,200 MPa, which is approximately two to three times stronger than lithium disilicate and far beyond what natural enamel can produce.
The reason zirconia displaced older crown materials is largely about failure modes. Porcelain-fused-to-metal crowns, the standard for decades, fail primarily through porcelain chipping off the metal substructure. Veneered zirconia crowns, an earlier iteration, had the same problem. A 2025 retrospective cohort study comparing monolithic and porcelain-fused zirconia crowns over 10 years found survival rates of 86.0% for monolithic and 71.0% for porcelain-fused zirconia. The gap is entirely explained by chipping on the veneered version.
Modern zirconia crowns are monolithic, meaning a single continuous block of material with no layered porcelain veneer. This eliminates the weakest point in older crown designs. A prospective 5-year study specifically evaluating Lava Plus monolithic zirconia crowns on premolars and molars found a survival rate of 98% after 5 years. Patients getting Lava Plus zirconia crowns in Vietnam at a clinic using this system can reference the same published data when assessing long-term outcomes.
The material is also fully biocompatible, chemically inert, and does not corrode. For patients with metal sensitivities, it eliminates the allergy risk that exists with porcelain-fused-to-metal systems.
Zirconia vs Emax vs PFM: how to choose the right crown material
When zirconia is the right choice
Zirconia’s strength makes it the standard for posterior teeth, meaning premolars and molars where biting force is highest. Its resistance to fracture under heavy load is unmatched by any other all-ceramic material.
For patients comparing zirconia vs Emax crown options in Vietnam, the clearest guide is tooth position: zirconia for back teeth where strength matters most, Emax for front teeth where light transmission and natural appearance take priority.
It is also the recommended material for implant-supported crowns. A systematic review and meta-analysis found a 5-year survival rate of 97.6% for zirconia implant-supported single crowns, and its dimensional stability under implant loading conditions makes it the clinician’s preferred choice for this application.
Patients with bruxism are better served by zirconia than by any other ceramic. The material’s fracture resistance makes it far less likely to fail under the sustained forces that grinding generates.
Modern multilayer zirconia has significantly improved the aesthetic performance of the material, with gradient translucency from the gumline to the tip of the tooth. For anterior teeth where appearance is the priority, high-translucency zirconia is now a clinically viable option where it would not have been five years ago.
When Emax is the better choice
Emax has a strength of 530 MPa, lower than zirconia but sufficient for anterior and premolar cases. Its defining advantage is optical. The crystal microstructure of lithium disilicate allows light to pass through and scatter in a way that closely mimics natural enamel, giving front teeth the depth and translucency that monolithic zirconia, even high-translucency grades, does not fully replicate.
For patients restoring front teeth where the result will be directly visible and compared to adjacent natural teeth, Emax remains the clinical gold standard for aesthetics. At Delia, Emax crowns start from $290 per tooth with a 20-year warranty.
The material is not recommended for molars or for patients with bruxism, where biting force exceeds what lithium disilicate can reliably withstand over the long term.
When PFM still makes sense
Porcelain-fused-to-metal crowns have the longest clinical track record of any crown type, with data spanning more than 50 years. A 2025 university-based retrospective study comparing monolithic zirconia and metal-ceramic crowns found an overall survival rate of 91.5% for both types within the study follow-up period, with similar clinical complications between groups.
The grey-black line that can appear at the gumline as tissue recedes over time is the main reason PFM has been largely replaced by all-ceramic materials for anterior teeth. For posterior teeth in budget-conscious cases, or where matching existing PFM restorations is clinically relevant, PFM remains a practical option. At Delia, Ceramill all-ceramic crowns, an entry-level alternative to PFM, start from $190 per tooth with a 10-year warranty.
The clinical data behind zirconia crowns
The evidence base for zirconia is now substantial. The key data points patients should know:
Meta-analyses report 5-year survival rates of 95 to 98% for zirconia crowns. Individual studies show 92.9% survival at 10 years for veneered zirconia designs. For monolithic designs, which have replaced veneered in modern practice, the prospective Lava Plus study reported 98% survival at 5 years with no fractures recorded.
The key distinction is monolithic versus veneered. The 10-year survival difference between monolithic zirconia (86.0%) and porcelain-fused zirconia (71.0%) in the 2025 retrospective study reflects the chipping problem that makes layered designs less durable. Modern clinics use monolithic designs for this reason.
Two risk factors for crown complications identified in clinical research are worth noting: molar crowns carry higher complication risk than premolar crowns, and upper jaw crowns carry higher risk than lower jaw crowns. Neither factor changes the material recommendation, but both are relevant for patients to understand when discussing longevity expectations with their dentist.
Wear on opposing natural teeth is also relevant. Properly polished and glazed zirconia produces low wear on adjacent teeth, comparable to natural enamel. Unglazed or rough zirconia surfaces are more abrasive under biting force, which is why the finishing step in fabrication matter
| Crown type | Survival rate | Follow-up period | Main clinical takeaway |
|---|---|---|---|
| Zirconia implant-supported single crowns | 97.6% | 5 years | Strong mid-term survival and reliable daily performance. |
| Monolithic zirconia crowns, Lava Plus study | 98.0% | 5 years | Excellent survival, with no fractures recorded in the prospective study. |
| Monolithic zirconia crowns | 86.0% | 10 years | Better long-term survival than layered zirconia in the 2025 retrospective study. |
| Porcelain-fused zirconia crowns | 71.0% | 10 years | Lower survival, mainly because layered designs are more prone to chipping. |
| Veneered zirconia designs | 92.9% | 10 years | Good long-term result, but still less durable than modern monolithic designs. |
Zirconia crown cost in Vietnam vs Australia, the US, and the UK
Lava Plus is manufactured by 3M and imported into Vietnam at international wholesale pricing, the same product placed in Sydney or London. What changes between markets is the cost of the dentist’s time, the lab technician’s work, clinic rent, and support staff. In Vietnam those costs are a fraction of Western equivalents, which is why the same 3M crown costs $350 at Delia versus AUD 1,500 or more in Australia.
For comparison, a zirconia crown in Australia typically runs between AUD 1,500 and AUD 2,500 per tooth. In the US, the range is $1,200 to $3,500. In the UK, £900 to £2,000.
The material cost for Lava Plus zirconia is similar globally, as it is an imported product traded at international wholesale prices. The price difference reflects labor costs, clinic rent, and operational overhead in Vietnam, not a difference in the crown material itself.
For a patient restoring six posterior teeth with Lava Plus Zirconia at Delia, the total treatment cost starts from $2,100. The equivalent in Australia, using the same 3M material, would be AUD 9,000 to AUD 15,000. Including return flights and accommodation, the savings across a six-crown case is substantial.
How Delia International Dental Clinic handles zirconia crown cases
At Delia International Dental Clinic, zirconia crown treatment follows a 2 to 3 visit process across 4 to 5 days, structured around the international patient’s schedule.
The first visit before Whatsapp consultation is Digital Smile Design, shade selection under natural light, tooth preparation under local anesthesia, and temporary crown fitting. The second visit covers the trial fitting of the permanent Lava Plus crown, adjustment of shape, bite, and color, and final cementation. A follow-up check for bite adjustment and comfort is included.
The trial step before cementation is non-negotiable. Every crown is seated and reviewed under multiple light conditions, including natural light, before anything is bonded permanently. The patient confirms the result before the appointment ends.
Lava Plus Zirconia crowns at Delia come with a 30-year written warranty, documented at the end of treatment. For international patients, the clinic coordinates hotel accommodation near the clinic and provides English-language aftercare instructions before departure.

Final thoughts
Zirconia is not one material but a category, and the clinical performance depends heavily on whether the crown is monolithic or veneered, which brand and grade is used, and how it is fabricated and finished. The survival data for modern monolithic zirconia, including the Lava Plus system specifically, is among the strongest in restorative dentistry.
The question for patients is not whether zirconia is reliable. It is which type, from which brand, placed by which team, with what warranty documentation. Those four questions are more predictive of outcome than any country-level comparison.
