David James Clark, DDS, joins with Dr. George Schmidt during the latest podcast episode. Dr. Clark explains the art and science of monolithic injection-molded composite dentistry and talks about utilizing injection-molding of composites with modern preparations, super-anatomic clear matrices and heated multi-viscosity composite to solve so many problems without resorting to crowns. (Dr Clark is a speaker at AGD's upcoming scientific session in Montreal, July 9-12.)

Dr. Clark is director of Bioclear Learning Centers International. He founded the Academy of Microscope Enhanced Dentistry, creates curriculum for dental schools and has lectured in 25 countries. He developed the Bioclear Matrix System for placement of biologically appropriate and esthetically pleasing direct composite restorations for facilitating injection-molding of the Clark Class I and Class II preparations, diastema closure, and black triangle elimination combined with papilla regeneration. The Clark Class I and Class II preparations and restorations are now being evaluated in in vivo and in vitro studies. He owns several patents. He published the first guide to dentinal and enamel cracks based on clinical microscope dentistry (16× magnification). Clark is a 1986 graduate of the University of Washington School of Dentistry.
