5 Reasons Dental Labs Are Switching To 4D Plus Zirconia Blocks

In today’s fast-paced dental industry, dental labs are constantly looking for materials that offer efficiency, reliability, aesthetic excellence, and cost-effectiveness. Among the wide range of dental restoration materials available, 4D Plus Zirconia Blocks have emerged as a revolutionary solution that checks every box. More and more dental labs across the world are making the switch — and for good reason.

At HaHasmile, we are proud to be at the forefront of this shift. With over a decade of manufacturing expertise and a global customer base in over 100 countries, our factory-direct model allows labs to access premium-quality zirconia products at competitive prices. Our 4D Zirconia Blocks, made from 100% Japanese-imported TOSOH powder, are a game-changer in the dental industry. Here’s why dental labs are choosing us and switching to 4D Plus Zirconia Blocks.

1. Superior Aesthetics and Natural Translucency

One of the top reasons dental labs prefer 4D Plus Zirconia Blocks is their unmatched aesthetic properties. These blocks are designed with 8 layers of color overlay and 15 gradient layers, mimicking the natural shading and translucency of real teeth. From the cervical to the incisal area, there is a natural increase in translucency — ranging from 43% up to 57% — which allows for an authentic appearance in every restoration.

This natural gradient in translucency and color gives technicians the ability to create lifelike crowns, veneers, and full-arch restorations without excessive staining or layering. Patients are increasingly demanding restorations that are indistinguishable from their natural teeth, and our 4D Blocks meet this expectation flawlessly.

2. Optimal Strength and Versatility

While aesthetics are crucial, strength and reliability are equally important — especially for multi-unit bridges and posterior restorations. 4D Plus Zirconia Blocks feature a unique strength gradient, starting at 1050 MPa at the cervical zone and transitioning to 700 MPa at the incisal edge. This ensures both durability and functional longevity, even under high bite forces.

This is why they can be used across a broad scope of applications, including:

• Crowns

• Veneers

• Inlays & Onlays

• Anterior and Posterior Restorations

• Long-span Bridges

• Full-arch Implant Cases

Through the application of 4D Plus Zirconia Blocks, laboratories can create almost any dental restoration with one material. Such "all-in-one" versatility streamlines inventory management and increases productivity.

3. Efficiency and Cost Savings with Direct-from-Factory Pricing

Price is always a prime concern for dental laboratories, particularly high-volume laboratories. While many of our competitors utilize multiple distribution channels, we are selling the Zirconia Blocks directly from the factory and therefore are passing savings of nearly 30% against agent pricing to our customers.

By running an online direct sales business, we eliminate the middlemen and pass the savings on to our customers. Also, our huge monthly production capacity of 60,000+ pieces means that supply is consistent and turnaround times are quick.

Labs no longer have to sacrifice quality for affordability. With us, they get both.

4. International-Grade Quality and Consistency

Each of our 4D Plus Zirconia Blocks is made from 100% imported nano-grade Japanese TOSOH zirconia powder. This ensures ultra-fine particle size, even distribution, and a consistent, high-quality product every time.

Our blocks are manufactured using Cold Isostatic Pressing (CIP) technology and pre-sintered at low temperatures to provide consistent density and stability. Each zirconia block is inspected strictly by our Quality Supervision Department before it leaves our factory. This dedication to quality has resulted in CE, FDA, and ISO certifications — a reflection of the international-standard quality in our manufacturing process.

With more than a decade of experience in zirconia production and over 100 committed personnel, we ensure material dependability, case after case.

5. Meeting Real Patient Demands for Comfort and Appearance

Today’s dental patients are more informed and have higher expectations than ever before. They want restorations that feel natural, look beautiful, and last long. 4D Plus Zirconia Blocks deliver on all three fronts.

Thanks to their optimal blend of strength and translucency, restorations fabricated from these blocks feel lighter, require minimal adjustments, and look indistinguishable from natural dentition. Whether it’s a single anterior crown or a full-arch restoration, patients appreciate the comfort and seamless integration.

This high level of patient satisfaction, in turn, enhances the reputation of the dental lab and encourages repeat business from dentists and clinics.
