3M True Definition Scanner
The CAD CAM technology has brought amazing contributions to various industries and in Dentistry, Computer Aided Design, Computer Aided Manufacturing is offered in the form of CEREC, (Chairside Economical Restoration of Esthetic Ceramics). Through the CAD CAM, digital technology is conveniently and practically utilized to provide patients with a better treatment option. Removing the laboratory technician from the picture, ceramic restorations (be it crowns, veneers or fillings) are fabricated by the Sydney dentist using a machine and are delivered to the patient, on the same day.
CAD CAM CEREC is definitely impressive. Those who are able to afford it can enjoy its amazing features, but it really still remains to be costly—enter 3M True Definition Scanner, 3M’s answer to the expensive digital diagnostic technology. Especially with the developments with this technology, coming in the following years, you can expect so much more from it.
- Precision. Digital technology allows perfect recording of detail that no other impression material can exactly manufacture. A lot of discrepancy occur with the use of rubber impression materials—and a lot of things are at play here. The digital picture produces accurate models that will aid in the success of the overall treatment process.
- Ease. On the side of the patient, going digital will mean no mess and hassle-free cast fabrications. Dental impressions can be quite uncomfortable. The trays are forced into the mouth along with the rubbery material and it often brings the patient to gag. Digital imaging removes the need for this. Records and models are created easily.
- Collaboration. With the technology, users enjoy a cloud-based system of collaboration between the dentist, laboratory and others. This makes diagnosis and fabrication so much easier.
Today there are already several machines available, but the 3M True Definition Scanner is the one that has the smallest camera with 3D video capability. Through this technology, dentists are able to capture and simultaneously view a true replica of the oral anatomy.
There remains some discrepancy with the workflow, however, but I remain hopeful that things will be resolved eventually. Today, it still takes a few days for actual models to be fabricated, which poses the inquiry of whether or not such models are actually necessary. “Do we really need models?” – if the machine is so accurate we may be able to be “model-less” for the simple cases. Let’s see what the future holds, but it certainly is exciting to see this in the flesh.

Every Sydney dentist makes use of a curing light. Composite restorations and resin cements are cured or are set using a light. A flowable or mouldable material utilised for restorative and luting purposes are hardened using a light that is gun or pen type and may be with or without a cord.
In the dental office, we make use of new equipment. Kerr have come out with a new curing light that utilises a very different technology in the battery. I was involved with the product evaluation that was ran about 2 years ago at Kerr HQ in the USA, and we were blown away with the new technology.
You are probably familiar with traditional curing lights. Cordless lights come with a battery console, where the battery may be charged and it takes a few minutes for the system to go from empty to fully-charged, so dental practitioners have become accustomed to pre-charging the batteries before use, even keeping a spare equipment as backup. The Kerr curing light is truly amazing. It makes use of the ultracapacitor technology to re-energize the battery to full power in under 40 seconds—this means that the waiting time is cut down significantly. Although ultra capacitors are similar in size and shape to traditional batteries, they work much differently—re-energizing in a matter of seconds, and maintaining their energy capacity year after year. The unit also has a built in radiometer to ensure appropriate power output. You have an efficient equipment that is powerful and definitely reliable.
The only downside is that the current tips that are used on the previous Demi lights cannot be used on this one, so for those of you that have multiple tips stored, be mindful that they will be deemed useless for the new Kerr curing light.
In practical terms, the U-40 Ultracapacitor-powered Kerr Demi Ultra is never more than 40 seconds away from being able to deliver 25 ten-second cures. See more at: http://www.kerrdental.com/kerrdental-curinglight-demi-ultra#sthash.Ke226rAx.dpuf.

Depending on the case presented to the Sydney dentist, there will be instances when the needs of the patient will go beyond what is usually done, just so health, function and aesthetics could be restored.
Mucograft seal is collagen membrane matrix that may be applied to the patient’s mouth. It is a synthetically fabricated material made from purified type 1 collagen so that it can guide, promote and hasten tissue healing for the following cases:
- Difficult tooth extraction that involved extreme bone loss, such as in the case of impacted teeth removal.
- Dental implant placement procedures on areas with insufficient bone. When diagnostic evidence reveals poor bone level and quality, it could be improved with bone grafts and matrices.
- Immediate loading of dental implants following a tooth extraction to gain proper stability.
- Tissue replacement after removal of bony defect or pathology, when gum tissue has been lost from the surgery.
- Ridge augmentation procedures for cosmetic or treatment purposes, either for removal dentures or dental implant placement.
- Soft tissue grafting procedures as a result of gum recession or disease, to successfully cover exposed tooth or bone.
- Sinus lifting procedure for treatment purposes.
After the procedure, after the grafting material is placed the tissue soft tissue is brought back and to enhance healing and success. Behaving as a soft tissue covering or dressing, the collagen material is placed, sometimes to hold the bone graft.
The people at Geistlich have produced a new collagen matrix named Mucograft ® Seal. It comes in a convenient circular shape and is indicated for the sealing of extraction sockets with preserved buccal walls in combination with Geistlich Bio-Oss ® Collagen in Ridge Preservation procedures. The collagen matrix allows predictable soft tissue dimensions and provides an alternative to soft-tissue grafts. In other words, treatment procedures provided with the collagen are given a higher success rate; and the provision of the material bring forth a more aesthetically appealing surgical site.
When a Sydney dentist is faced with an important cosmetic problem on a patient, one of the things he makes sure to do right is to pick the right shade. This is determined, by matching the existing teeth and making certain that the shade is appropriate to the complexion.
Matching the color and choosing the right shade for the restoration is important because the results and the overall satisfaction of the patient depends on this. A patient comes into a Sydney dentist’s office to get better smile and if the smile does not look natural and even, he will not be happy. The success of every case will rely on how happy the patient is with the results and sometimes it will all be about choosing the right restorative material.
There has always been the concern with veneering porcelain chipping from a traditional zirconia crown, and the use of monotlithic full contour zirconia has recently become extremely popular to a Sydney dentist due to the high physical properties of these materials.
Historically it has always been the veneering (fedspathic) porcelain failing with fracturing or chipping. The trade off was always the poor aesthetics that followed due to the dense polycrystalline structures.
Recently, Noritake has released a full contour zirconia restoration using the new Katana Zirconia ML, a gradational multilayered zirconia disc with four layers of color–35% enamel, 15% of the first gradation layer, 15% of the second gradation layer and 35% dentin–that offers the look of layered porcelain. The pre-colored multilayered shades provide esthetic results without manual dipping or staining and eliminate additional material costs. KATANA Zirconia ML discs are available in three shades: A-Light, A-Dark and B-Light (KATANA HT–a high translucent mono-colored zirconia–is also available in three shades: HT10, HT12 and HT13). So far this material exceeds the aesthetics of other full contour zirconias, so look out for this material.
