RE: TRIMMING DENTAL MODEL

The conventional approach to fabrication of dental appliances is to take impression with alginate or rubber based material then pour the impression in dental stone for subsequent laboratory procedures that will culminate into fabrication of prescribed prostheses. The world of fabrication of dental appliances is fast changing from the plaster/production room to digital spaces. How do I mean? You no longer need to deal with physical impressions anymore in some few laboratories in advanced world but virtual impressions are made and from there virtual fabrication is done and virtual information is passed to the milling machine which eventually produces the prosthesis. Milling machines can handle a number of materials ranging from metal to plastic and others. Although it is not yet bed of of roses for the dental industry but there is hope that in the coming decades fabrication of dental prostheses will move completely from plaster rooms to digital spaces.
Where is Africa in all these tremendous breakthroughs?
