Cleanliness & Cross Infection Control
This Laboratory aims to operate a level of
cleanliness, which satisfies and promotes good
housekeeping polices to the mutual advantage of
Laboratory members and customers alike. These
procedures must be adhered to at all time to
safeguard the customer, to protect the
laboratory and ensure compliance with the
current legislative requirements. It is the
responsibility of every member in the
Laboratory to be aware of the danger of cross
infection and to take every precaution to
prevent cross infection/contamination of our
produce. All Laboratory members are responsible
for taking appropriate care when dealing with
materials, which have been in direct contact
with patients and to take all reasonable
precautions to operate
cleanliness controls/practices.
Cleanliness of Devices at Dispatch
Prior to the dispatch of any Medical Device,
its condition will be reviewed. This reviews
the adequacy of the device to meet with the
customers satisfaction and also takes into
account the suitability of the device in terms
of its cleanliness. The cleanliness standard
operated by the Laboratory ensures there is
neither obvious contamination nor materials
surplus from the manufacture of the device.
Irrespective of the method of dispatch, the
packaging used will be free from obvious
contamination.
Work Areas
Work areas will be kept in a condition,
which ensures that the product does not
deteriorate due to damp and dirt. The
cleanliness of both the work and surrounding
area is the responsibility of the laboratory
staff working in that area.
GC Gradia
The GC GRADIA family is a unique light-cured composite system for indirect restorations such as crowns, bridges, inlays and veneers and all types of direct restorations whether it’s in the anterior or the posterior region.
With the GC GRADIA family, you can handle all your aesthetically demanding restorations easier and quicker. Due to the remarkable shade's adaptation to the surrounding tooth structure, outstanding natural looking aesthetic and long-lasting restorations can easily be achieved.
The GC GRADIA family consists of GC GRADIA, the laboratory system for making high-end aesthetic crown and bridge work that has proven itself for over 5 years now.
A restoration made from composite material has many beneficial properties such as strength and durability, but although composite also has good aesthetic qualities, it does not give the natural tooth appearance of porcelain. That is, until now!
New GC GRADIA is a unique light-cured Micro-Ceramic-Composite system for crowns, bridges, inlays and veneers, which compared to conventional composites, gives restorations with a colour tone close to that of natural teeth. A product of GC research, GC GRADIA’s more natural tooth appearance has been achieved by developing its resin colour tones in conjunction with its application technique. This combined approach to development has created a system where the final restoration is of optimum hue, brightness and chroma, whilst minimizing the paleness inherent with composites. The result is a restoration with an opalescence comparable to porcelains and close to natural teeth which you.
IPS e.max Press
The innovative IPS e.max Press lithium disilicate glass-ceramic (LS2) offers excellent fit, form and function combined with high strength of 400 MPa. The material is supplied in four levels of translucency and two sizes for maximum flexibility. The resulting restorations exhibit lifelike esthetics, independent of the shade of the preparations.
IPS e.max Press is used to produce single-tooth restorations, bridges in the anterior and premolar region and implant superstructures. Minimally invasive inlays and onlays (1 mm) and thin veneers (0.3 mm) round off the indication range.
The two investment materials IPS PressVEST and IPS PressVEST Speed are available for processing IPS e.max Press.
A wide selection of ingots is offered from which you can choose the one that suits your preferred processing technique (staining, cut-back or layering technique) and the case at hand (e.g. discoloured preparation). The restorations are characterized or veneered with matching staining materials or layering ceramic from the IPS e.max Ceram assortment. The press material for the fabrication of full-contour restorations is available in 16 A-D and four Bleach BL shades. The materials for the layering technique are supplied in group shades.
Receipt of Impressions
On receipt of an impression, the Lab ticket
will be viewed to check for any stated product
contamination, the general condition of the
impression will be considered and should
cleaning be required then it will be cleaned
using a suitable method. It may be sprayed using
a suitable cross infection spray, immersed in a
cleaning solution or other measure dependent
upon the level of contamination.
Straumann CADCAM
We use Straumann’s CADCAM technology to be more flexible and more efficient in our daily work. Etkon™ es1 - digital laser technology designed to scan within 10 microns of accuracy, the etkon™ es1 scanner produces a 3d digital image, creating a meticulous fit for crowns, bridges and custom abutments time after time.
The cutting-edge production technology at the Straumann CADCAM production centre turns data into precise frameworks for crowns and bridges. The centralized Straumann CADCAM production centre features process technologies for zirconium dioxide ceramics, aluminium oxide ceramics, titanium, CoCr alloys, and resin-based materials.
Zerion - high-performance Zirconium Dioxide Ceramics
This metal-free, bio-compatible product is ideal for anterior teeth esthetics and large-span bridges. zerion presents an alternative for patients who are sensitive to metals.
zerion’s high strength and fracture toughness comes from the tetragonal, polycrystalline framework structure. It achieves fatigue strength of up to 1300 MPa after a dense sintering process.
- Metal-free restorations allow for better esthetical results compared to casted metal solutions.
- The composition of ZrO2 helps to minimize microcracks during manufacturing.
Zerion can be used for:
- single copings and primary crowns
- customized abutments
- large-span bridges
- superstructures on implants
- high esthetic demands
- patients with sensitivity to metals
Ticon™ - Titanium
Titanium is well established in medical and dental applications for its strength and lightweight properties. ticon™ is an ideal option for patients who need crowns, bridges and restorations.
Straumann’s proprietary CAM processing eliminates the structural material flaws of alloys that are cast. Cast alloys could lead to issues with overall strength and integrity of the coping or framework.
Material properties of ticon™:
- Can be X-rayed
- Conduct low levels of heat
- Maintain a bioinert state toward acids and physiological solutions
- Create an optimal bond between titanium and veneer ceramic
Coron™ - Cobalt-Chromium Alloy
The CoCr alloy coronTM1 is the economic alternative to precious metals. The applications range from single copings to large-span bridges and full contour posterior restorations. The mechanical properties of the milling material comply with the requirements of the international standards EN ISO 16744 and ISO 9693.
Straumann’s proprietary CAM processing eliminates the structural material flaws of alloys that are cast. Cast alloys could lead to issues with overall strength and integrity of the coping or framework.
- Nickel-free, cadmium-free, beryllium-free, iron-free, indium-free and gallium-free (ISO 6871)
- Optimal bond between coron alloy and veneer ceramic
- Carbon-free laser welding properties
- No oxidation firing necessary
- Single copings and primary crowns
- Large-span bridges
