Implantology is a continually evolving discipline that has been making notable progress in the design and production of full dentures used for reestablishing masticatory functions and aesthetics in edentulous or partially edentulous patients. Let’s go deeper into new material application and usage.
Cobalt-chrome is a metal alloy that has been used for medical and dental device production for decades. It is resistant to mechanical stress, durable, and biocompatible, which makes it the ideal choice for many different applications, including bone implants. Let’s take a closer look at the benefits of cobalt-chrome:
CEPROSEM is an Italian Milling center known for its cutting-edge technologies and highly-trained operators. CEPROSEM developed a need to create a semi-finished product for inclined holes that could overcome all the limitations present in existing applications for on-axis holes that can interfere with the incisal part of the tooth. Using only in-house assets, CEPROSEM developed a solution.
In this process, a 20° inclined hole is created with respect to the insertion axis of the bone implant and the connection is identified. Connection detection occurs automatically thanks to the specific “identification” “Identify” function present in MillBox dental CAM software. The activation of this function allows the automatic insertion of the cutting and fitting parameters for implant creation. The object is then positioned on the blank and calculated to obtain the .nc file to be sent to the machine.
After access holes have been created through multiple drilling cycles, the operation proceeds to create the inclined hole and the screwed channels on the implant. The hole on the connection side is created by standard milling operations, while the screw top refining is carried out with a special “T” tool. The match is performed by algorithms within MillBox CAM software, managing both the roughing phase and a second phase of machining with only axial micro-increments, to correctly define the screw channel. Tool life is determined based on the accuracy of the processing.
As mentioned above, performing flexible operations like these are possible due to the availability and usage of cobalt-chrome material, a versatile alloy which allows customizable design and fitting. Screw-retained cobalt-chrome semi-finished products represent a significant step in implant dentistry evolution, helping to improve the quality and longevity of implant treatments.
