Materials of Fixed Dentures and Removable Dentures

Dentures can be broadly classified into fixed and removable types, depending on whether they can be removed by the patient. HONCHON SMILE, a leading dental zirconia block supplier, introduces the common materials used for these dentures and their respective advantages.

Fixed Dentures

Fixed dentures are permanently attached to abutment teeth, providing aesthetics, comfort, and efficient chewing similar to natural teeth. The materials commonly used for fixed dentures are porcelain-fused-to-metal (PFM) crowns and all-ceramic (zirconia) crowns.

Porcelain-Fused-to-Metal Crowns
PFM crowns have a metal base covered with porcelain. While durable, the metal base can limit aesthetics due to opacity and may cause gingival discoloration over time. Precious metal bases reduce this effect but increase cost. PFMs are generally more affordable and provide sufficient strength for most patients.

All-Ceramic (Zirconia) Crowns
Zirconia crowns combine excellent aesthetics, biocompatibility, and mechanical strength, making them ideal for high-end restorations. They mimic natural teeth in translucency and color, offering superior visual results without compromising durability.

Overall, while PFM crowns meet general needs, zirconia all-ceramic crowns are the premium choice for patients seeking long-lasting and highly aesthetic fixed dentures.

Removable Dentures

When oral conditions do not support fixed prosthetics, removable dentures are an alternative. Their aesthetics, chewing efficiency, and comfort vary depending on the design and materials.

Glued Resin Dentures
Made mainly from methacrylic resin, these dentures are simple, affordable, and easy to repair. However, the plastic base is thicker, which can increase bulk and lengthen the adaptation period. They are often used as temporary or transitional solutions.

Metal Cast Bracket Dentures
These use an integrated casting process to form strong metal frameworks with connectors and retainers, combined with artificial teeth and resin saddles. Materials include cobalt-chromium alloys and pure titanium. Advantages include smaller size, less tissue coverage, comfort, easy cleaning, and high strength. Titanium frameworks are highly biocompatible and corrosion-resistant, making them increasingly popular in modern dentistry.

HONCHON SMILE provides a wide range of dual PMMA blanks for removable dentures, compatible with open CAD/CAM systems and ZirkonZahn systems. Made from 100% high-quality, non-toxic resin, these blanks ensure precision and safety.

PEEK Blocks

HONCHON also offers PEEK (Polyetheretherketone) blocks, used in medical applications such as finger prostheses, intervertebral discs, and hip implants for over 35 years. PEEK combines excellent biocompatibility and mechanical properties similar to bone, making it suitable for removable partial denture frameworks and retainers. It is highly resistant to radiation, chemicals, and wear, making it durable under challenging conditions.
