MO zirconia (Medium Opacity) has low translucency, which makes it very effective at masking tooth discoloration, dark stumps, and implants. It is suitable for cases requiring greater coverage and a stable color base. LT zirconia (Low Translucency), on the other hand, has medium translucency, allowing for a more natural aesthetic effect. Due to its good balance between strength and esthetics, LT zirconia is often used in extensive frameworks and prosthetic bridges. Material selection depends on the clinical situation and the expected final result.

Zirconia etching is a chemical or mechanical surface preparation process performed before cementation or ceramic layering. The goal is to increase adhesion by removing the surface layer and creating micro-retentive features that improve the retention of bonding materials. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center we use the specialized ZIRCOS-E system for zirconia etching, which ensures high effectiveness and process safety. Properly performed zirconia etching is crucial for the durability and stability of the final prosthetic restoration.

A glass support is used when a prosthetic bridge contains more than two pontics or when an additional, cantilevered pontic is planned—that is, more than one unit. It is used to reinforce and stabilize the framework, improving the distribution of chewing forces and preventing excessive loading of bridge elements. The prerequisites are healed gingiva in the area where the support will rest, and the presence of natural antagonistic teeth or fixed restorations, such as metal-ceramic or zirconia bridges. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, every decision to use a support is preceded by technical analysis—to ensure safety and long-term functionality.

A zirconia blocker is a special material in liquid or paste form used during zirconia staining to mask discolorations, dark tooth stumps, or implant components that might show through a translucent crown or bridge structure. Its main task is to block unwanted colors and create a more neutral background for ceramic layering. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we use a blocker when the clinical case requires better coverage—especially in esthetic zones or with thin prosthetic structures. The appropriate blocker type depends on the zirconia system and the expected final effect.

At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we manufacture extensive zirconia bridges, including full-arch spans. However, according to material manufacturers’ recommendations, we do not recommend exceeding two pontics between abutments. We can produce such frameworks, but only without warranty. Primomill® is not responsible for the durability of such constructions because the material manufacturer does not guarantee their strength under clinical conditions. In such cases, we suggest alternative technical solutions or a consultation with our technical team prior to proceeding.

Yes, clasps in skeletal dentures made with laser sintering exhibit appropriate flexibility, provided they are correctly designed in terms of the length, thickness, and width of the retentive arm. The flexibility of the clasps is also influenced by the chemical composition of the metal powder used, which determines the mechanical properties of the finished structure. Laser sintering enables very precise reproduction of geometry and ensures structural homogeneity, which translates into durability and stable retention. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we pay special attention to clasp design to ensure proper retention and long-term functionality.

To ensure that a given ceramic is suitable for use with a structure manufactured using laser sintering technology, you should check the ceramic manufacturer’s recommendations for working with metal substructures—especially regarding the coefficient of thermal expansion (CTE). At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we recommend ceramics intended for cobalt-chromium alloys with a standard CTE. Information about the cobalt-chromium powder used for our structures can be found on our website in the “Materials” section: https://primomill.com/en/materials

Yes, for metal structures—especially those made with laser sintering—it is recommended to use a bond layer before ceramic layering. The bond creates an intermediate layer that improves ceramic adhesion to the metal, increases the durability of the connection, and reduces the risk of chipping.

Yes, for metal frameworks it is recommended to perform oxidation before the first ceramic firing. Oxidation reveals any contaminants on the metal surface and improves the bonding of the ceramic layer with the substructure. This process increases connection stability and reduces the risk of defects in the fired ceramic.

To properly connect the skeletal framework with ready-made modular parts, use cold-cured acrylic. Before joining the elements, sandblast and thoroughly clean the surfaces, then prepare a master model with proper isolation to prevent uncontrolled bonding to the model. The remaining stages of working with printed elements proceed analogously to traditional acrylic dentures—through standard mechanical finishing and hand polishing. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we recommend this method as durable, proven, and technically safe for joining our structures with modular gingival-tooth parts.

TrueDent 3D technology is a revolutionary solution that completely changes the approach to manufacturing dentures and acrylic elements for skeletal dentures. It performs exceptionally well in implant-supported constructions, where it is used both for temporary dentures and permanent acrylic restorations, delivering fast, precise, and esthetic results. A major advantage is the ability to print the gingival and tooth parts simultaneously as a single, unified element. The teeth are neither glued nor mechanically seated—they form a cohesive whole with the baseplate, eliminating the typical problem of teeth detaching from dentures. The risk of damage exists only in the case of a fracture of the entire structure, which is very rare. The TrueDent system also allows you to completely eliminate working with gypsum, water, and other messy materials, significantly streamlining the process and improving cleanliness and organization in the laboratory. Additionally, any repairs of dentures made with this technology can be carried out using cold-cure acrylic, just like with classic acrylic dentures. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we consider TrueDent a true breakthrough in single-process printing—reliable, clean, and modern.

Yes, dentures made with TrueDent 3D technology can be relined without issue, either indirectly in the laboratory or directly in the patient’s mouth—depending on the clinical case. Standard cold-cure acrylics are used for relining, just as with classic acrylic dentures. Before relining, the denture surface should be properly prepared—cleaned and roughened—to ensure good adhesion of the new material layer. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we recommend checking the fit before relining and consulting any changes with the attending clinician.

Laser sintering (SLM – Selective Laser Melting) is a modern additive technology in which metal structures are created layer by layer by selectively melting metal powder with a laser beam. In dental prosthetics, this technology is used mainly for skeletal dentures, crowns, bridges, and ceramic substructures, with high precision and repeatability. At Primomill® Milling Center, Laser Sintering, and 3D Printing Center, we use high-quality cobalt-chromium powder, which ensures durability, biocompatibility, and precise reproduction of the digital design. Laser sintering eliminates many drawbacks of traditional casting, such as air bubbles or distortions, and allows even the most complex prosthetic frameworks to be produced.
