Zirconia has fundamentally changed crown and bridge dentistry. For New Jersey dentists seeking a reliable source of precision-milled zirconia crowns with consistent quality, fast turnaround, and a lab team that genuinely understands the material, BioDent Laboratory in Matawan, NJ delivers on all counts.
The Three Types of Zirconia: Choosing the Right Grade
Monolithic Zirconia: Maximum Strength for Posterior Cases
Monolithic — or full-contour — zirconia is milled as a single solid block with no layered porcelain overlay. This eliminates the primary failure mode of PFM and early layered zirconia: chipping and delamination. A monolithic zirconia crown will not chip. It will not fracture under normal occlusal loads. It is the most durable crown option available today.
BioDent mills monolithic zirconia from pre-shaded blocks matched to VITA shade designations. External staining and glazing produce natural surface texture and occlusal anatomy that reads as a natural tooth rather than a synthetic white block.
Layered Zirconia: Strength and Aesthetics Combined
Layered zirconia uses a milled zirconia coping as a base, over which ceramic porcelain is hand-applied and fired by a skilled ceramist. This construction allows for greater aesthetic control — depth, translucency gradients, and characterization that approach natural tooth structure. BioDent recommends layered zirconia for anteriors and premolars in esthetic zones where shade complexity requires ceramic characterization beyond what staining of a monolithic crown can achieve.
Ultra-Translucent Zirconia: Anterior Aesthetics Without Compromise
Ultra-translucent zirconia features translucency levels that rival lithium disilicate (E.max) while retaining substantially higher flexural strength. It is the material of choice for anterior crown cases where incisal translucency and depth are required. BioDent recommends ultra-translucent zirconia for implant-supported anterior crowns and for cases where layered porcelain is not preferred.
BioDent’s Zirconia Milling Process
BioDent mills zirconia restorations in-house using CAD/CAM technology integrated with the lab’s full digital workflow. Cases submitted digitally via intraoral scan are processed directly from the scan file.
Design and Milling
Each case is designed by BioDent’s CAD technicians with precise margin placement, emergence profile design, and occlusal contact optimization. After milling, zirconia crowns undergo sintering — the high-temperature firing stage that transforms the milled block into a dense, fully crystallized ceramic. Post-sintering, restorations are finished, stained, glazed, and quality-checked before dispatch.
Quality Control
BioDent’s quality control for zirconia includes margin inspection under magnification, occlusal contact verification on articulated models, and shade matching review by a senior technician. Restorations that do not meet specification are remade before they leave the lab.
Turnaround Times
- Monolithic and ultra-translucent zirconia: 5–7 business days
- Layered zirconia: 7–10 business days
- Rush options available for urgent cases
- Digital cases process faster — no model pour-up stage
Zirconia vs. PFM: Why Dentists Are Making the Switch
- No metal margin graying: Zirconia has no metal substructure, so there is no gray shadow even if tissue recedes.
- No porcelain chipping: Monolithic zirconia eliminates the porcelain-to-metal bond failure mode entirely.
- Better biocompatibility: Zirconia is inert and non-corrosive. Metal alloys in PFM can corrode over time.
- Comparable or superior strength: Modern zirconia matches or exceeds PFM for single-unit and short-span bridge applications.
Zirconia vs. E.max: Choosing Between Two Premium Materials
Both zirconia and E.max are excellent options. The choice is clinical, not a question of quality. For a detailed breakdown of E.max pricing and when to choose it over zirconia, see our guide on E.max crown cost and value.
- Strength: Zirconia is significantly stronger. For posteriors, heavy occlusal loads, and bruxism cases, zirconia is safer.
- Aesthetics: E.max has traditionally offered slightly superior anterior translucency. Ultra-translucent zirconia has closed most of that gap.
- Adjustability: E.max is easier to adjust chairside. Zirconia must be polished after adjustment to prevent wear on opposing dentition.
BioDent’s recommendation: monolithic zirconia for posteriors as the default; ultra-translucent zirconia or E.max for anteriors based on translucency requirements; layered zirconia for esthetic cases where ceramic depth is required and bruxism is not a concern.
Why NJ Dentists Choose BioDent for Zirconia
BioDent competes on the combination of quality, communication, and proximity that a regional New Jersey lab can offer. Every case is milled and finished in-house at the Matawan, NJ facility — no offshore fabrication, no third-party milling centers. When you have a clinical question, you speak directly to the technician building your restoration. Visit our dentist page to learn more.
Frequently Asked Questions
Which zirconia grade for bruxism patients?
For patients with confirmed bruxism or parafunction, BioDent recommends standard or high-strength monolithic zirconia. Its fracture resistance makes it far more appropriate in high-load situations. Note bruxism on the case prescription so technicians can design with reinforced connectors and conservative occlusal anatomy.
Can BioDent match zirconia to adjacent natural teeth?
Yes. BioDent’s technicians are experienced in shade matching zirconia to natural dentition and existing restorations. Clinical photographs under standardized lighting — ideally with a shade tab in the image — are strongly encouraged for complex matching cases.
How does BioDent handle zirconia remakes?
If a zirconia crown from BioDent doesn’t fit, doesn’t match the prescribed shade within clinical tolerance, or has a fabrication defect, BioDent will remake the case at no charge. Include photos and a description of the issue when requesting a remake.
Does BioDent offer rush zirconia crowns?
Rush cases with two to three business day turnaround are available for an additional fee, subject to production capacity. Standard turnaround is five to seven business days for monolithic zirconia. Contact BioDent’s team to discuss rush case scheduling.
