How Do We Design Full-Mouth Dental Prosthetics At 21D?

Discover the innovative engineering behind prosthetics at 21D, where precision-crafted solutions replace traditional teeth with state-of-the-art materials like titanium and PMMA. This article explores how our advanced techniques and cutting-edge technology deliver durable, functional, and natural-looking dental solutions, ensuring optimal comfort and longevity for every patient.

The engineering behind prosthetics at 21D

At 21D, what we create are not "teeth" in the conventional sense but highly engineered prosthetics. These prosthetics are designed to serve as replacements for teeth, but their functionality and structure go far beyond traditional expectations. Here’s an in-depth look at how we craft these innovative solutions and why they are pivotal in modern dental care.

Materials matter: Titanium and PMMA

Our prosthetics are made using PMMA (Polymethyl Methacrylate) blocks and titanium, both of which are solid, pre-made materials. Unlike traditional methods that might involve casting or manual crafting, our approach utilises medical-grade milling machines to shape these materials with precision and consistency. The result is unparalleled accuracy, ensuring an optimal fit for each individual.

The Two Components:

1. Titanium Bar:
   This serves as the foundation, screwed directly onto the implant heads. The surface that contacts the gum is highly polished to create a self-maintaining, hygienic finish, while the opposite side is roughened to form a strong bond with the veneer.
2. PMMA Veneer:
   This lightweight yet durable component is bonded to the titanium bar. Designed for everyday functionality, it allows for normal activities like eating an apple or enjoying a steak. However, it’s not designed for extreme stress, such as biting on ice cubes or frozen chocolate—behaviours that should be avoided with natural teeth as well.

Why PMMA and Titanium?

Unlike zirconia or ceramics, which are harder but brittle, PMMA provides a crucial advantage: flexibility and fail-safes.

• Shock Absorption: Natural teeth are cushioned by the periodontal ligament, which implants lack. PMMA mimics this shock-absorbing effect, protecting the jawbone and implants.
• Repairability: While prosthetics can break, the titanium bar remains virtually indestructible. Replacing a PMMA veneer is straightforward compared to the more invasive and costly repairs required for zirconia or ceramic solutions.
• Non-Porous Surface: PMMA’s long polymer chains make it non-porous, unlike ceramics, which can absorb oral fluids if their glaze is damaged. This enhances both durability and hygiene.

Precision in design and fabrication

Every prosthetic is designed using a 3D model of the patient’s anatomy. From the exact placement of implants to the creation of the titanium bar, every detail is tailored to the individual. This process ensures:

• Optimal Fit: The titanium bar and veneer are designed to align perfectly.
• Long-Term Success: Precise engineering minimises stress on implants, promoting longevity.
• Easy Adjustments: Minor misalignments or bite corrections can be easily calibrated chairside using PMMA veneers without damaging the structure.

Addressing aesthetic and functional concerns

The final prosthetic is designed to look and feel as natural as possible. The pink gum area is meticulously painted to blend seamlessly with the patient’s natural lip line. While the prosthetics are engineered, the outcome is indistinguishable from natural teeth in appearance, giving patients renewed confidence and functionality.

Commitment to longevity

At 21D, our focus is on longevity and patient well-being. We aim to provide solutions that last without requiring invasive interventions. Our philosophy is simple: by choosing materials and designs that balance aesthetics, durability, and functionality, we ensure that our patients receive care that exceeds expectations.

Why choose 21D for prosthetics?

Our use of PMMA and titanium reflects a commitment to engineering excellence. From the initial 3D scans to the final quality checks, every step of the process is conducted with precision and care. Whether it’s the ease of maintenance, superior durability, or enhanced comfort, our prosthetics are designed to transform lives.

At 21D, we don’t just replace teeth; we engineer confidence, functionality, and smiles that last a lifetime.
