Overview and Composition
Procera AllCeram stands out among dental ceramics due to its unique composition:
99.9% Pure Alumina: Ensures high strength, biocompatibility, and consistent mechanical properties.
No Glass Phase: Eliminates weaknesses associated with glass-ceramic interfaces, enhancing fracture resistance.
This material’s purity and dense microstructure make it ideal for applications requiring strength and precision, such as single crowns and fixed partial dentures.
Manufacturing Process
The Procera system employs a sophisticated CAD/CAM manufacturing process that ensures accuracy and consistency:
Digital Scanning
The prepared tooth or die is scanned using a mechanical touch probe scanner, creating a precise digital model.
Data Transmission
The digital data is transmitted to a central production facility (originally in Sweden), where the framework is fabricated.
Die Fabrication
An enlarged die is produced to accommodate the 15-20% shrinkage during sintering.
Powder Processing
High-purity alumina powder is compacted onto the enlarged die using dry pressing or slip-casting techniques.
Sintering
The alumina is sintered at 1550°C, resulting in a fully dense ceramic coping with minimal porosity.
Veneering
The sintered alumina coping is veneered with a specially formulated low-fusing ceramic (e.g., AllCeram or Ducera Dental) matched to the thermal expansion of alumina.
This meticulous process ensures high precision, strength, and aesthetic potential, making Procera AllCeram a reliable choice for dental restorations.
Material Properties
Procera AllCeram demonstrates exceptional mechanical and structural properties:
Flexural Strength: 600-700 MPa, significantly higher than conventional feldspathic porcelains.
Density: Nearly 100% theoretical density, achieved through complete sintering.
Purity: 99.9% pure alumina, ensuring consistent material performance and biocompatibility.
Grain Size: Fine, uniform grain structure contributes to high mechanical strength and crack resistance.
These properties make Procera AllCeram suitable for applications requiring durability and precision, particularly in posterior crowns and fixed partial dentures.
Clinical Applications and Performance
Procera AllCeram has proven its reliability in long-term clinical studies:
Survival Rates
5-10 Year Survival Rates: Studies show survival rates exceeding 90% for single crowns over extended periods (5-10.5 years).
Indications
Single Crowns: Ideal for anterior and posterior crowns due to its strength and precision.
Fixed Partial Dentures (FPDs): Adapted for frameworks waxed as individual copings and then connected.
Performance
Procera AllCeram’s ability to withstand functional loads and its excellent fit make it a preferred choice for restorations requiring longevity and predictable outcomes.
Bonding Characteristics
Bonding densely sintered alumina requires specific protocols to ensure long-term durability:
Surface Treatment: Air particle abrasion creates micromechanical retention for bonding.
Adhesive Systems: Specialized primers and resin cements are required for optimal adhesion.
Long-Term Durability: Studies emphasize the importance of proper surface treatment and adhesive selection for restoration longevity.
Dental professionals should follow these protocols to maximize the clinical success of Procera restorations.
Advantages
Procera AllCeram offers several benefits that make it stand out in the realm of dental ceramics:
High Strength: Superior mechanical properties due to pure, densely sintered alumina.
Precision Fit: CAD/CAM technology ensures accurate and consistent fit.
Biocompatibility: Excellent tissue response due to high-purity alumina.
No Glass Phase: Eliminates potential weaknesses associated with glass-ceramic interfaces.
Quality Control: Centralized production ensures consistent material properties and reliability.
These advantages make Procera AllCeram a trusted choice for both dentists and patients seeking durable and predictable restorations.
Limitations
Despite its strengths, Procera AllCeram has some limitations:
Opacity: High opacity limits use in highly aesthetic anterior regions without careful veneering.
Processing Complexity: Requires specialized CAD/CAM equipment and expertise.
Brittleness: Like all ceramics, susceptible to fracture under excessive loads.
Cost: Higher initial investment compared to conventional techniques.
Understanding these limitations is essential for proper case selection and achieving optimal results.
Evolution and Current Status
Since its inception, the Procera system has evolved significantly:
Decentralized Production: Modern systems now allow in-lab production, reducing dependency on centralized manufacturing.
Material Variations: Introduction of zirconia-based Procera systems to complement alumina.
Scanner Technology: Transition from mechanical to optical scanning systems for improved accuracy.
These advancements ensure Procera AllCeram remains a relevant and competitive option in the rapidly evolving field of dental ceramics.
Comparative Performance
When compared to other all-ceramic systems, Procera AllCeram demonstrates distinct advantages:
Higher Strength: Outperforms glass-infiltrated systems like In-Ceram.
More Opaque: Less translucent than lithium disilicate systems, requiring careful veneering in anterior applications.
Similar Strength: Comparable mechanical properties to other CAD/CAM alumina systems, with unique processing benefits.
Procera’s combination of strength, precision, and biocompatibility makes it a versatile choice for many clinical scenarios.
Conclusion
Procera AllCeram represents a milestone in dental ceramic technology, combining 99.9% pure alumina, advanced CAD/CAM manufacturing, and proven clinical performance. While newer materials like zirconia and lithium disilicate offer alternatives, Procera AllCeram remains a trusted option for cases requiring strength, precision, and reliability.
