Astratech has released their Cresco(r) system for ensuring passive fit on screw-retained implant bridges. This system allows for up to 17 degrees of angle correction for screw-retained bridges using bendable wax tubes giving maximum flexibility in terms of being able to compensate for angled implant placement when bone quality and quantity are poor. Using a Cad-Cam-like milling machine corrects the casting distortion of prosthetic superstructures to a very high degree of precision. The majority of implant systems are supported.
