The precision of a machine or technology is only as good as the doctor using it and prescribing it for their patients. The training, education and experience of the doctor must be as complete as possible. Dr Pechous is a specialist in the dental services he provides. Crowns, bridges, dentures, partial dentures and dental implants all require precision in the steps needed to produce them. Dr. Pechous and Dr. Richards choose carefully which and when radiographs are taken. There are many guidelines that we follow. Radiographs allow us to see everything we cannot see with our own eyes.
