CERAMIC TEETH
Each and every tooth given by God is as precious as Pearl and no tooth, given by God is “Extra”. If you lose a tooth, or the tooth is removed by dentist, then replacement of that missing tooth with artificial fix tooth, is of utmost importance. Following are consequences of not replacing missing tooth/teeth.
1. Drifting of adjacent teeth towards missing tooth space.
2. Impingement of opposing tooth on gums of missing tooth.
3. Space formation between neighbour teeth and gums.
4. Food getting stuck between teeth.
5. Cavities/ Decay of teeth adjacent to missing tooth space.
6. Bad breadth due to food lodgment and bacterial accumulation.
7. Chewing difficulties / One-sided chewing.
8. Asymmetrical jaw movements.
9. Temporo Mandibular Joint (TMJ) and Muscle problems in long run.
10. Total 9 (NINE) nearby teeth can get spoiled, just by not replacing one missing tooth.
Replacement of missing teeth is done by ceramic teeth which is manufactured by DMLS and CAD- CAM high tech technologies.
DMLS SYSTEM
Selective laser sintering (SLS) is a part of additive manufacturing where a high-power-density laser is used to melt and fuse metallic powders together.
Since the components are built layer by layer, it is possible to design organic geometries, internal features and challenging passages that could not be cast or otherwise machined.
DMLS produces strong, durable metal parts that work well as both functional prototypes or end-use production parts.
The mechanical properties of samples produced using direct metal laser sintering differ from those manufactured using casting.
These improvement of the mechanical properties of the direct metal laser sintering samples has been attributed to a very fine microstructure
CAD-CAM
CAD-CAM is one of the highly competent dental lab technologies.
• The cast is made in the conventional way, but the die is ditched to make the margin easier to identify during scanning.
• The die is mapped using a contact scanner
• The shape of the prepared tooth is transferred to the computer screen.
• The design of the restoration is transferred to the manufacturer via computer line.
• The production process starts with milling an enlarged die to compensate for the sintering
shrinkage.
• An enlarged ALL CERAMIC coping is milled that shrinks to the desired shape after sintering.
CAD/CAM has improved the quality of prostheses in dentistry and standardised the production process. It has increased productivity and the opportunity to work with new materials with a high level of accuracy.
It is recommended that one needs to get artificial fix tooth fixed in place, as early as possible; either with Dental Implants or Ceramic Bridges.
