Prosthodontists have the ability of replacing a singe or numerous teeth when their condition does not allow the repair by a simple filling.The proshtetic works are ussually manufacured by acrylic, zirconia or ceramic materials.

Afterwards, the dental techinician is responisble of manufacturing our replacement. Finally, the patient leaves the dental office with a new tooth in his mouth which is esthetic and trully impossible to differentiate from his/her own teeth.
