What is Zirconia Crown?

Zirconia (zirconium dioxide, ZrO2) for dental crowns is yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) with 3 mol% yttria for phase stabilization. Modern multilayered zirconia integrates progressive translucency from cervical to incisal to mimic natural tooth appearance. Generations include first-generation high-strength opaque zirconia, second-generation translucent (3Y-TZP), third-generation cubic (5Y-TZP, 6Y-TZP, lower strength but higher translucency) and fourth-generation multilayer.

CAD/CAM workflow involves digital impression (intraoral scanner), virtual design, milling from pre-sintered or fully-sintered blocks, and post-milling sintering at 1350-1550°C. Zirconia crowns can be monolithic (entirely zirconia) or layered (zirconia core with porcelain veneer for esthetics, but with risk of porcelain chipping). Modern monolithic translucent zirconia is preferred for posterior teeth due to strength.

Indications include posterior crowns (especially molars with parafunctional habits), anterior crowns (with translucent zirconia), implant-supported crowns, full-arch fixed prosthetics (zirconia bridges) and implant abutments. Advantages include exceptional strength, biocompatibility, low plaque accumulation, no metal allergy and excellent esthetics. Disadvantages include high cost, conservative tooth preparation requirements (1-1.5 mm reduction), antagonist tooth wear concerns (mitigated by glazing/polishing), and difficulty in adjustment without diamond burs.

Symptoms

Restoration, not a disease — clinical indications:
Significant tooth structure loss requiring crown
Posterior tooth restoration after large restoration
Anterior tooth esthetic restoration
Single missing tooth replacement on implant
Bruxism patient requiring durable restoration
Metal allergy contraindicating PFM crowns
Discolored tooth requiring full-coverage cover-up

Risk Factors

Patient and treatment risk factors:
Severe parafunctional habits (bruxism)
Inadequate occlusal clearance for thickness
Insufficient tooth structure for retention
Active periodontal disease
Poor oral hygiene with high caries risk
Cost considerations
Need for future endodontic access (difficult)
High occlusal forces requiring thicker design

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Tooth requiring full-coverage restoration
  • Anterior tooth with esthetic concerns
  • Posterior tooth restoration replacement
  • Implant-supported crown placement
  • Bruxism patient with restoration failures
  • Allergy to metal restorations (PFM)
  • Pre-prosthetic planning and consultation
  • Failed previous all-ceramic or PFM restoration

A dental implant is a titanium screw placed in the jawbone that supports a crown, bridge or denture, providing the closest possible function and aesthetics to a natural tooth.

Teeth Whitening

Ağız ve Diş Sağlığı

Teeth whitening lightens tooth color using hydrogen peroxide or carbamide peroxide gels. In-office (professional) bleaching uses higher concentrations with light activation for faster results; home bleaching uses custom trays with lower concentrations over 1–4 weeks. Safety depends on healthy teeth, correct concentration, isolation of gums and transient sensitivity management.

Gingival recession is the apical displacement of the gingival margin with exposure of the root surface. It may be localized or generalized and results from mechanical trauma, periodontal disease, thin biotype or anatomic factors. Recession can cause root sensitivity, caries and aesthetic concerns; management includes cause elimination and surgical root coverage when indicated.
