About

Dr. J.D. Preston is a pioneering figure in the integration of digital technologies into restorative dentistry, with a career-spanning focus on computer-aided design and manufacturing (CAD/CAM) systems. His seminal 1996 work, "CAD/CAM in dentistry," which has garnered 9 citations, laid foundational groundwork by systematically outlining the critical steps—from tooth preparation and elastic impression-taking to stone model fabrication—that bridge traditional clinical workflows with emerging digital fabrication. While modest in citation count, this contribution is notable for its early, prescient articulation of a paradigm shift that would later revolutionize prosthetic dentistry. Preston’s research demystified the technical requirements for chairside and laboratory-based CAD/CAM, helping practitioners understand the precision and efficiency gains possible through digital workflows. His work remains a touchstone for students and researchers exploring the evolution from analog to digital dentistry, highlighting the meticulous procedural thinking required to translate clinical needs into machine-readable designs. By clarifying these foundational processes, Preston enabled subsequent innovations in same-day restorations and customized prosthetics, cementing his role as a quiet but essential architect of modern digital dentistry.
