Flexible PMMA Materials help solve adaptation and provisional needs while keeping margins accurate. We understand the expenses of recreations and shade incompatibility to a dental lab. Here we describe real-world decisions, lab procedures, product documentation and how to obtain reproducible results with materials that can be depended upon.

Why materials and millability matter for modern labs

A reliable supply of Dental Zirconia Blocks and milling-compatible PMMA keeps cases moving. We would suggest the choice of blocks with the tested translucency gradients and flexural strength to ensure that frameworks and veneers resemble natural teeth. The real-life range of color gradient and strength found in our 95mm 4D Pro Multilayer Zirconia Block can support long-span restorations.

Product highlight — 95mm 4D Pro Multilayer Zirconia Block

This multilayer block is of 95mm size and length (10-25mm) in various lengths. It also has 8 layers overlay and 15 gradient layers. The bending strength is between 700Mpa and 1200Mpa and shade matching is simpler by anterior and posterior restoration due to the variation in translucency of the layers which is 43 to 57 percent. These are veneer, crown, inlay, onlay, implant and full-arch bridges. Sizes: 98mm/95mm/71mm; thickness 10/12/14/16/18/20/22/25mm. 

The shades in use include A1-D4 and OM1-OM3. Prices: $65.00 -100.00 per piece based on size and density. Pre-sintered blocks are porous before final sintering and thus should be handled with care.

How Flexible PMMA Materials speed provisional workflows

Flexible PMMA Materials are ideal for temporary crowns and complex provisionals. They mill to perfection, polish and offer the elasticity required to place and extract temporaries without chipping. Same-day provisionals, prototypes and try-ins before final sintering Use PMMA.

 Block good PMMAs minimize the time spent in milling and enhance the quality of surface finish. Incorporation into a standard work procedure reduces the turnaround and minimizes time of adjustment on the model.

Clinical and lab performance of Dental Zirconia Blocks

Dental Zirconia Blocks like the 4D Pro offer a strength gradient that supports long bridge spans while keeping incisal translucency natural. By mapping the percent thickness of the layers to strength (15 percent at 700Mpa down to eighth layer 15 percent at 1200Mpa), technicians will be able to place restorations with predictable mechanical properties. Pre-sintered CIP technology has uniform density, but must be handled carefully to prevent breakage due to the remaining porosity.

Sintering and accessory support

Apply the Dental Fix Firing Sintering Paste to glaze and fix the restorations in the firing process. The paste is non-toxic and translucent and is 10ml in size. Apply a pea size where necessary; once the paste is fired it leaves a white mass which is easily removable. The lid should be tightened after use, it should be sealed against light and stored at room temperature, in a clean and dry place. Do not subject to excessive vibration or collision in storage.

Practical tips for shops and labs

• Standardize block sizes and shades to reduce inventory variance.
• Keep a sintering curve profile for each furnace and each block type.
• Use Flexible PMMA Materials for provisional workflows and cross-check fits before final sintering.
• Track translucency and shade outcomes; Dental Zirconia Blocks with graded translucency reduce polishing time.
• Label milling burs and speeds for each material to extend tool life.

Quality control and pricing notes

In  Flexible PMMA Materials we run color checks and sintering trials to ensure the 4D Pro Multilayer runs predictably in common furnaces. Shades such as A1-A4, B1-B4, C1-C4, D2-D4 and OM1-OM3 are available. 95mm 4D Pro Multilayer costs 65-100 dollars each based on size and thickness. Our laboratory staff suggest that the trial milling of one block on each new batch be performed to verify the firing curves prior to the full-case milling. Movable pre-sintered blocks are light because of porosity, and so they should be handled with care before final sintering.

Shipping, warranty and ordering

Shipping is done by big couriers (DHL Express, FedEx Express, 4PX and special lines) that are selected by per destination policy. Normal processing time is 7 days; transit time is 3-30 days depending on the country. In case of unsatisfactory items received, contact customer service within 7 days to talk about returns, the buyer will cover the cost of returning the goods. HaHasmile is on top of quality product issues and provides fast responsive technical assistance to solve firing or shade problems.

Why choose our supply chain

We are a manufacturer with a history of production of zirconia and PMMA of more than a decade. Stable lots, monthly capacity and reactive shipping allow laboratories to grow without unexpected delays. Remakes and wasted lab time are minimised by our zirconia and PMMA consumables. We have got quality control and monthly production of 60,000 blocks and color control to ensure the batches are predictable.

FAQ

Q: Can zirconia blocks be used in full-arch bridges?

A Yes, multilayer blocks are recommended in full-arch bridges and long-span restorations because they have a strength gradient.

Q: What do I do with sintering paste?

A: Store the paste closed and without light and in a dry place and at room temperature.

Q: What sizes do you stock?

A: 95mm blocks available in 10mm -25mm thick, and in all series of A, B, C, D and OM.
