Three-dimensional diagnosis & treatment planning: The use of 3-D facial imaging and 3-D cone beam CT in orthodontics and dentistry
by William E. Harrell, Jr, DMD Evaluating the “Anatomic Truth” of our patient’s anatomy in 3-D has traditionally been limited to evaluating the patient “live” in the chair and by the evaluations of dental study models (either plaster or 3-D digital representations). New 3-D technologies (3-D facial scanning and 3-D cone beam CBCT – also […]Read More
