How to Prevent Zirconia Bridge Breakages – A Complete Guide for Overseas Patients
If you are missing all the teeth or unhappy with the traditional removable dentures, then full mouth dental implants are the best and only mode of fixed teeth replacement. Conventional implants, when placed in the cortical bone, Osseo Integrate with the bone and aid in full mouth reconstruction, allowing immediate loading of teeth. This procedure aids in Long-term success dental implants as permanent teeth can be fixed in a single visit, regardless of the amount of bone present, without requiring additional surgical procedures like sinus lifts and bone grafts.
After implant placement, the choice of materials for prosthetics in a full mouth dental implants restoration plays a critical role in achieving durability, aesthetics, and functionality. Here’s a detailed overview of the commonly used materials.
1. Hybrid Composite Teeth on Implants
Hybrid composite teeth are a long-term provisional option for implant-supported restorations, offering a balance between strength, aesthetics, and affordability. They are commonly used as interim prostheses for All-on-4 vs All-on-6 implants, where Acrylic teeth are attached to a metal framework supported by dental implants.
Advantages of Hybrid Composite Teeth on Implants:
- Aesthetics – They mimic the natural translucency and texture of real teeth.
- Lightweight – Less strain on implants compared to zirconia crowns and bridges.
- Repairability – Can be easily repaired or modified in case of damage.
- Cost-Effective – More affordable than full Zirconia or ceramic restorations.
Disadvantages
Hybrid composite prosthesis are prone to wear and tear and can only be used as an interim set of fixed bridges before the final zirconia crowns and bridges or DMLS Metal ceramic prosthesis can be fixed on the implants. Some dentists follow the two-phase implantation technique, where procedures like sinus lifts and bone grafts are performed to increase bone volume. This process includes waiting for 4 to 6 months before placing implants, followed by another waiting period of 3 months for implant integration.
However, full mouth dental implants placed in dense cortical basal bone do not require any waiting period, and permanent teeth can be fixed in around a week, regardless of bone loss. This full arch implant restoration approach apart from saving time, is non-invasive, economical, and provides long-term success dental implants as the implants engage the individual’s native bone instead of the unpredictable grafted bone.
2. Direct Metal Laser Sintering (DMLS)
DMLS is a 3D printing technology widely used in dentistry for creating high-precision, metal- based dental restorations. It involves using laser to sinter powdered metal into complex structures layer by layer.
Applications of DMLS in Dental Implants
- Crowns and Bridges – Fabrication of metal substructures for porcelain-fused-to-metal (PFM) restorations.
- Full-metal crowns for posterior teeth.
- Full arch implant restoration – Customized abutments and bars for implant-supported prosthetics.
Advantages of DMLS:
- Precision and Accuracy – Highly accurate designs with minimal tolerances ensure an excellent fit.
- Good Strength and Durability – DMLS restorations can last 10–20 years with proper care.
- Cost-Effectiveness – More affordable compared to Zirconia bridges.
Limitations
DMLS restorations are aesthetically second to Zirconia crowns and bridges.
3. Zirconia Crowns and Bridges
Zirconia crowns and bridges are advanced dental prosthetics crafted from zirconium dioxide. They are highly durable, bio-compatible and aesthetically pleasing, making them an ideal choice for multi-unit bridges.
Advantages of Zirconia Crowns and Bridges
- Strength and Durability – High fracture resistance, making them suitable for patients with heavy bite forces or bruxism.
- Aesthetics – Natural tooth-like translucency with customizable color options.
- Biocompatibility – Non-allergenic and gentle on soft tissues.
- Precision Fit – CAD/CAM technology ensures accurate fabrication for a perfect fit.
- Resistance to Wear and Staining – Polished surfaces resist plaque accumulation.
Limitations of Zirconia Crowns and Bridges
- Higher cost of full mouth dental implants when choosing zirconia restorations.
- Not suitable for posterior bridges due to potential breakage at joints or pontics.
While zirconia crowns and bridges are ideal for anterior teeth and single crowns in the posterior region, bridges made of Zirconia are not preferred for the molars due to high chewing forces. For a long-term success dental implants strategy, Zirconia crowns require a solid foundation underneath to sustain grinding forces.
Preventing Zirconia Bridge Breakages
The best way to achieve a break-resistant zirconia bridge is by ensuring proper implant placement. Placing 14 implants in each jaw, an implant for each & every tooth which is unnecessary and impractical.
- The All-on-6 technique is more than sufficient to replace all 14 teeth in each jaw.
- In some cases, the All-on-8 technique may be used, but exceeding 8 implants can jeopardize the implant lifespan.
- Basal implants can accommodate up to 10-12 implants in good bone quality, but in cases of low bone volume, placing 8 implants itself becomes impractical.
For patients with poor bone quality—especially in the posterior upper jaw where the sinus expands or in the lower jaw where nerves limit implant placement—placing small implants and placing unsupported Zirconia crowns and bridges can lead to long-term failure.
How to solve Zirconia Bridge Breakages ?
Titanium Framework for Long-Lasting Zirconia Bridges
The best way to provide Zirconia bridges while placing optimal number of implants is by using a titanium framework. This framework splints the implants, ensuring stability and preventing breakage at pontics.
Titanium Bar Under Zirconia Prosthesis
A titanium bar is a lightweight yet strong metal framework used in long-span full mouth dental implants and hybrid dentures. This method ensures long-term success by preventing zirconia bridges from breaking under excessive forces.
Advantages of Titanium Framework in Full Mouth Dental Implants
- Corrosion Resistance – Titanium remains stable in the moist oral environment, ensuring longevity.
- Versatility – Suitable for both screw-retained and cement-retained prostheses.
- Precision Fit – CAD/CAM technology ensures an accurate fit for optimal.
Limitations
- Higher cost of full mouth dental implants due to advanced fabrication techniques.
- Technique Sensitivity – Requires skilled technicians and precise CAD/CAM equipment.
Conclusion
A titanium bar is a lightweight yet strong metal framework used in long-span full mouth dental implants and hybrid dentures. This method ensures long-term success by A titanium framework under a Zirconia prosthesis is a great choice for patients who want strong, long-lasting, and natural-looking teeth.it is considered best dental implant solutions for overseas patients. Although it requires precise work and may cost more, it offers excellent durability, aesthetics, and long term success. Whether you have good or low bone volume, choosing a titanium-supported Zirconia bridge is a smarter option than using Zirconia alone. Without a titanium frame, Zirconia bridges are more likely to break in areas where there is no implant support. For more information or to consult an expert whats app (+91-9849008623).
