  5. International-Standard BioUltra Crown Procedure at Smilux

Step 1: 3D ConeBeam CT Scan for Bone & Gum Assessment

A safe treatment plan always begins with precise diagnostics. At Smilux, the first step is 3D ConeBeam CT scanning, not a standard 2D X-ray, but a full 3D map that allows clinicians to visualize the entire oral structure for the most accurate planning.

This technology provides full visualization of the jawbone, gum tissue, nerve canals, and tooth roots from every angle, eliminating unexpected risks. It enables precise planning and complete peace of mind from the start.

Step 2: Dental and Health Evaluation

Assess bone density and height to determine structural support and identify bone loss or gum recession.

Evaluate gum tissue and occlusion to identify inflammation, thickness, firmness, and bite misalignment.

Use intraoral endoscopy and magnification to detect hidden decay, cracks, enamel wear, or untreated pulp issues.

Gum and Dental Health:

  • Gingivitis or advanced periodontitis → must be treated before restoration.
  • Large cavities or pulpitis → require root canal therapy first.
  • Mobility from bone loss → may require bone grafting or implants.
  • Severe malocclusion → orthodontics may be needed first.

Assessment of systemic health: review medical history (such as diabetes, cardiovascular conditions, chronic gingivitis, etc.) to ensure safety during the procedure.

From this data, the doctor will determine the most appropriate treatment plan, because not everyone is a suitable candidate for dental crowns. Certain conditions make the body slower to heal or increase the risk of complications after tooth preparation or anesthesia:

  • Severe cardiovascular disease (under treatment or unstable), such as heart failure, myocardial infarction, or arrhythmias.
  • Uncontrolled diabetes (HbA1c > 7%), which leads to higher infection risk and delayed wound healing.
  • Blood disorders such as coagulation disorders, thrombocytopenia, or patients currently taking anticoagulants.
  • Advanced liver or kidney disease, which affects the metabolism of anesthetics and antibiotics.
  • Cancer patients undergoing radiotherapy or chemotherapy, especially in the head and neck region, where gum tissues are weakened and more susceptible to necrosis.

Immunological conditions (such as HIV/AIDS or lupus) that reduce the body’s ability to adapt to restorative materials.

Step 3: Consultation on Porcelain Crown Options

After obtaining the 3D CT scan results and evaluating the overall condition of the teeth and gums, Smilux dentists will recommend the most suitable restorative solution based on the patient’s aesthetic goals, chewing function, and budget. The three most common options include:

1. All-Ceramic Crowns

All-ceramic crowns such as Zirconia, E.max, Lava, or Orodent are the most popular choices today thanks to being made entirely from pure ceramic blocks metal-free, safe, and highly durable.

When combined with BioUltra technology (a biologically engineered ceramic system with minimal tooth reduction), this becomes an optimal restorative solution, offering natural aesthetics and maximum preservation of the natural tooth.

Advantages:

  • Natural translucency and shade similar to real teeth.
  • No black gum lines over time.
  • High strength and durability, suitable for both anterior and posterior teeth.
  • Excellent biocompatibility, does not irritate the gums.

Best suited for: Clients seeking long-term aesthetic restoration or full smile enhancement.

    2. Porcelain-Fused-to-Metal (PFM) Crowns – Chrome Cobalt

    These crowns have an inner metal substructure made from Nickel-Chromium or Titanium alloy, covered with an outer ceramic layer to mimic natural tooth color.

    Advantages:

    • High strength and excellent load-bearing performance.

    • Affordable cost suitable for many clients.

    • Quick installation process; effective for restoring fractured, decayed, or worn teeth.

    Best suited for: Posterior teeth (molars), where strength and chewing force are prioritized over aesthetics.

      3. Porcelain Veneers

      Porcelain Veneers are a non-invasive cosmetic method in which the dentist roughens only the enamel surface before bonding a thin ceramic shell on top.

      Advantages:

      • Preserves nearly the entire natural tooth structure.
      • Effectively masks imperfections such as yellowing, spacing, minor chips, or unsightly tooth shape.
      • Natural translucency for a bright, harmonious smile.
      • No sensitivity; chewing feels just like natural teeth.

      Best suited for: Patients with healthy teeth who want to enhance the aesthetic appearance of their front teeth without full-coverage restorations.

        4. Ceramic Dental Bridges

        A ceramic dental bridge is a fixed restoration used when one or several adjacent teeth are missing. The adjacent natural teeth are prepared as abutments, and a series of crowns are connected to replace the missing tooth or teeth.

        Advantages:

        • Restores chewing function.
        • High aesthetics with precisely crafted crowns that match natural teeth.
        • Quick procedure: completed in only two appointments.
        • Cost-effective while still providing strong durability and good aesthetics.

        Best suited for:

        • Patients missing 1-3 adjacent teeth with neighboring teeth still strong enough to serve as abutments.
        • Those seeking a fast, fixed restoration without implant surgery.
        • Clients wanting functional and aesthetic restoration at a more affordable cost.

        Step 4: Tooth Preparation and Temporary Crowns

        Tooth preparation often concerns patients due to fear of sensitivity, but at Smilux, this has been fully optimized. Thanks to the dentist’s skill combined with BioUltra technology, minimal reduction tooth preparation, the process is extremely gentle and quick.

        BioUltra offers high durability, prevents plaque accumulation, reduces gingival inflammation, provides antibacterial and anti-inflammatory benefits, and inhibits odor-causing bacteria, keeping the gums healthy and the oral cavity clean.

        After preparation, temporary crowns are placed so patients can eat and function normally until the final crowns are installed.

        Step 5: Dental Impressions and Crown Fabrication

        After tooth preparation, the dentist takes impressions using specialized dental wax. These are sent to the Smilux Labo, where technicians pour stone models and design the crowns with precision to ensure optimal fit, natural appearance, and long-term stability.

        Additionally, the process is enhanced with 5D CAD/CAM technology, enabling micron-level accuracy so the crowns fit perfectly with no discrepancies.

        Step 6: Final Crown Placement

        Once the Labo completes the fabrication based on the impressions, the patient returns to the clinic for final crown placement. The dentist will adjust shape, bite alignment, and chewing comfort to complete a naturally aesthetic smile.

        Before finishing, the dentist will:

        • Perform a final check on crown stability and guide the patient on how to chew during the first 48 hours.
        • Provide home-care instructions: oral hygiene techniques and foods to avoid to protect the crowns.
        • Schedule a follow-up appointment after 7-10 days to check occlusion and gum adaptation.

        FAQs

        Do porcelain crowns hurt, and do they require a lot of tooth reduction?

        No. With BioUltra technology, tooth preparation is ultra-thin only about 0.2-0.5 mm and performed with mild anesthesia, so there is no pain or sensitivity. Up to 90% of the natural tooth structure is preserved, ensuring maximum safety and comfort.

        How long does the BioUltra porcelain crown procedure take at Smilux?

        The entire process takes only two appointments, including 3D CT scanning, tooth preparation, impressions, temporary crowns, and final placement.

        Should I choose all-ceramic crowns, PFM crowns, or porcelain veneers?

        It depends on your dental condition and aesthetic goals:
        - All-ceramic crowns: the most advanced, durable, natural-looking option; suitable for all cases from single restorations to full-mouth rehabilitation.
        - PFM crowns: affordable and strong, ideal for restoring posterior teeth.
