CROWN AND BRIDGE
Improves the appearance and function of a smile.
ZIRCONIA MONOLITHIC & LAYERING
Omegaden Laboratory offers 2 types of zirconias, which are monolithic (full zirconia) and layering (zirconia core with porcelain finishing).
Monolithic - lower degree of translucency but a much higher flexural strength of more than 1200 Mpa.
*Suitable for posterior cases.
Layering - higher degree of translucency but has a flexural strength of more than 800 Mpa.
*Suitable for anterior cases.
For long bridges, we also mix the 2 types of zirconia to create a more aesthetically pleasing bridge without compromising its flexurel strength.
WHY ZIRCONIA CROWN & BRIDGES?
Able to match the colour of existing teeth
Extremely strong, requiring less tooth preparation than other materials
Able to be layered with porcelain, further improving its aesthetic appearance
Zirconia crowns can be bonded or cemented, giving dentists more options
Zirconia has the ability to be "milled", which quickens the time of completion
Biocompatible material - does not cause adverse reactions when implanted in the human body
The proven all-ceramics are easy to handle and produce customized results that fulfil the most exacting aesthetic standards.
The state-of-the-art IPS e.max system was launched more than a decade ago. It combines the benefits of lithium disilicate and fluorapatite glass-ceramics with those of zirconium oxide ceramics.
Omegaden Laboratory offers both press technique and e.max CAD (milled by our CAM unit). The all-ceramic materials cover a broad spectrum of indications to meet all types of patient requirements. The innovative IPS Ivocolor range of stains and glazes rounds-off this successful materials system.
Aesthetic requirement for all-ceramic prostheses is that they should possess sufficient translucency that matches your natural teeth
Emax based protheses do not contain alloy metal beneath the porcelain
Emax crowns are less likely to crack during clinical usage because it is made of lithium discilicate
Can be quickly fabricated by using CAD CAM milling
The crowns can be prepared in thin sections therefore requires minimal removal of natural tooth structure during preparation
It is not limited to all-ceramic crowns but also veneers, inlays, inlays, overlays, and even short-span bridges to replace the front teeth.
E-MAX CAD / E-MAX PRESS
PMMA (Poly-methyl methacrylate) is a clear plastic acrylic material that can be used as a replacement for glass.
A temporary crown is a provisional, short term restoration used in dentistry. The temporary material is designed using CAD/CAM and forms a tooth shape that protects the prepared tooth, preventing damage to the periodontal tissues (gums) and disguises the prepared tooth to a degree until the final, definitive restoration can be made.
PMMA milled crowns which comes in various colours are an adequate, temporary, fast and reliable way to save chairside time, whilst the hardness and resistance of the material is perfect for the preparation of provisional pieces.
Range of colours
High resistance to abrasion
Reduce chair side preparation
Prevents damage to the periodontal tissues
PORCELAIN BONDED (PFM)
Omegaden Laboratory's PFM cases are done by using the CAD software to ensure maximum precision on the crown's margin.
The porcelain fused to metal crown offers great aesthetics which provides a very attractive natural tooth like appearance. The substructure of the porcelain fused to metal crown is designed using our state of the art CAD/CAM facilities allowing for a precise, accurate fit for any type of preparation.
Porcelain fused to metal has the advantage of flexibility as they can be used on both anterior/posterior restorations and is versatile for any number of restorations.
High level of aesthetics achieved
Suitable for anterior & posterior restorations
Limitless size or length of restoration to be designed
Strength, function and reliability
Different type of alloys can be used - non precious or precious
Omegaden Laboratory offers non-precious, semi-precious and precious alloy for our full metal crown and bridge.
Compared to other crown types with metal, minimal amount of tooth structure has to be removed and wearing out of adjacent teeth is also minimal.
These crowns can withstand chewing and biting forces well and last for over a long period due to its metal material, which hardly breaks.
WHY FULL METAL CROWNS?
Tremendous metal strength
Crowns completely made of gold are of good quality
Causes minimal wearing of the surrounding teeth
Require little amount of filling for the tooth
Lasts for a long period, also resists chipping and breaking
Metal occlusal crowns, often constructed from non-precious metal alloys, are highly favored for their exceptional durability and long-lasting performance.
They emerge as the preferred choice, especially in the posterior teeth, where occlusal clearance is limited, and the impact of robust chewing forces is a significant concern. While these crowns may not boast the esthetic appeal of other options, their practical advantages, including robustness, cost-effectiveness, and suitability for areas with restricted occlusal clearance, make them a compelling choice.
In comparison to full porcelain coverage PFM crowns, metal occlusal crowns are notably more suitable for posterior teeth and the palatal region of anterior teeth, where visibility during a patient's smile is not a primary consideration.
WHY METAL OCCLUSAL?
Highly durable and resistant to wear
Provide strong support for the teeth
Requires less tooth reduction
Able to withstand the forces of biting and chewing over an extended period
Radiopaque, easier to identify issues or changes in X-rays
