Porcelain Fused Metal Crowns are dentistry’s primary choices for restorations. Once they are appropriately seated they come across to be the strongest, most reliable and are an esthetically good choice for both front and back teeth. Apart from having an excellent cosmetic appearance they prove to be the strongest since they can withstand heavy biting force.
Press to Metal (PTM) crowns are a modified version of PFMs wherein instead of the layering being made of porcelain, a wax pattern is made and ceramic ingot is pressed over the metal. Pressing metal ceramic means separating the design and colouring during the manufacturing process in order to optimize the final results.
The Press-to-metal© technique excludes the possibility of any shrinkage of the ceramic masses or of any changes in the metal substructure during the sintering process. This means that anatomical details and tailored ceramic shoulders retain their form throughout the entire working process.
The innovative IPS e.max Press lithium di-silicate glass-ceramic (LS2) offers excellent fit, form and function combined with high strength of 400 MPa. 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.
When functionality plays a more important role than aesthetics, full metal crowns are mostly used in posterior teeth. Full Metal Crowns preparation are specially prescribed in cases of Bruxism, since the fabrication required is minimal.
Suitable for the fabrication of both metal-supported and metal-free restorations, these new advanced indirect composites are micro-filled, light/heat-curing veneering composites for full-coverage and partial veneers.
