Royal Dental Laboratory Material - Innovative Solutions

Produces safe, bio-compatible, aesthetic temporary prostheses that are required to be replaced by a higher performance polymer due to wear and tear.

It is a thermoplastic (T-) or a chemoplastic (C-) polymethylmethacrylate (PMMA).

T-PMMA is produced using industrial polymerisation procedure for producing high purity PMMA with a theoretic level of purity of 99.9%. The residual 0.1% is non-cytotoxic and is therefore harmless.

C-PMMA is produced using a chain reaction which may generate free radicals. These radicals allow for the formation of long chains polymers. They may trigger allergies and material in-tolerances.

Material properties:

• Metal-free
• Strength – >65 mpa
• E- modulus – >2800mpa
• Indicated wearing time – 6 months

Indications:

These prosthesis have higher wear and tear and discolouration when compared with the higher performance polymers. Still, they have a distinct advantage of reducing the load on the underlying structures under circumstances of heavy bite force, paan- supari habit, bruxism, clenching etc. They can be used as a permanent prosthesis in such cases.

Increase the wearing time of the temporary resin prosthesis and can be used as an intermittent prosthesis. They offer even more polished aesthetics.

It is a polychrome composite polymer with 20% ceramic filler intermixed with the PMMA. It has a higher wearing time and strength.

This resultant optimized material mixture gives the dental prosthesis a natural colour gradient and an increased strength.

Material properties:

• Metal-free
• Strength – >100 mpa
• Indicated wear time 2 years
• E-modulus – >2200 mpa

Indications:

These materials can be used as a permanent prosthesis over natural tooth or implants. They do not discolour easily. They have a higher resistance to scratching and abrasion, hence the aesthetics last longer than resin.

It is a universal genius. They offer the most elegant, and varied solutions for a number of indications and can be used as a permanent prosthesis with an approved life span of 9+ years.

It is a cross linked composite polymer that offers higher physical values than conventional PMMA. They are manufactured under controlled environment of high temperature and pressure. As there are no use of dental glass or light cured plastics the love of color retention and plaque resistance is comparable with Ceramic restorations. They have been clinically proven and approved for over 9 years of use.

Advantages:

• Metal-Free with approved expected life of 9 years
• Plaque resistant
• High level of strength
• Aesthetic, translucent and opalescent

Material properties:

• Strength – >120 mpa with minimal solubility in saliva
• E-modulus – >2200 mpa

Indications:

Most versatile material. They can be used as permanent dental prosthesis with implant, natural tooth or both. They have an excellent gingival response and pressure absorbing capability.

The most physiologic properties of this frame work material are only surpassed by nature itself. It is as elastic, light and thermal conductivity as that of bone by making the patient’s feel at ease.

They have the highest aesthetic retention and resistance to scratching and abrasion. It is a bio-compatible polymer of polyether ketone and is strengthened using ceramic. They have been in use in body Implantology for over 30 years (intervertebral discs, hip joints etc). With the improvement by ceramic fillers these materials can now be used in dental applications especially as a framework.

Advantages:

• Anti allergic – no metal, oxide or monomer
• Weight and density is similar to natural bone
• Does not have a metallic taste
• Off peak effect – reduce the compression and torsion caused by chewing
• Heat conduction similar to teeth – increasing the comfort
• Low abrasion and good Versatility

Advantages of Royal Peek restorations:

Unbeatable convenient processing, Maximum customisability, Cuts like dentin, Conserving the antagonists, Optimal Osseointegration, Optimal gingival management, Longevity of the restoration, Natural oral feeling and chewing sensation, Natural aesthetics, Allows immediate restoration and one time treatment.

Material properties:

Can be used as permanent dental prosthetic framework, implant and natural tooth cases. They have excellent gingival management and pressure absorption.

• Flexural Strength – 180 mpa with almost no water solubility
• E-modulus – >4550 mpa
• Wear time 9 years

Class 1 photo polymers bio compatible resins which are built from additive laser process to delivery surgical guides, and splits which can be fitted as a framework or temporary supports. They are a Class I bio compatible resin (EN-ISO 10993-1:2009/AC:2010, USP Class VI) material. They are used in the dental industry by additive processes, hence allowing for construction of even the most complex prosthesis.

Indications:

They are used to create surgical guides and temporary splints. These material can be sterilized in the autoclave.

Material properties:

• Strength – >50 mpa
• E-modulus – >1500 mpa

Advantages:

• Anti allergic
• Non metallic
• Complex prosthesis
• Surgical guides

Flowable polymer which attached to the surfaces of the implant, natural teeth & high-performance polymers thereby creating a single unit for a more durable, success-oriented, & efficient dental prosthetic solutions. They are flow able, biocompatible polymers which create a chemical or mechanical bond between the two surfaces which may be of titanium, peek high-performance polymers. They themselves provide shock-absorbing capability to reduce the load on the inner structures. They have minimal dissolution in the saliva and are therefore stable for a long period of time.
