Columbia University-trained prosthodontist Nathan Hornsby, DDS, MSc (NPI 1164611455, California license 58078) practices implant prosthetics and full-mouth rehabilitation at 940 B Street in downtown San Diego. Hornsby completed a three-year prosthodontics residency at Columbia after earning his DDS there, producing a master's thesis on dental implant prosthetics that informs the evidence-based protocols now applied at this Tenth and B Street location — a research-driven standard of care shared by integrated medical providers like Elm Street Family Health Center in Bankers Hill. His undergraduate training at the University of Washington concentrated in molecular biology and genetics, grounding his prosthetic work in the biological principles governing osseointegration and peri-implant tissue response. Patients undergoing extended multi-appointment prosthodontic sequences sometimes coordinate anxiety management with behavioral health providers like Activate Balance Counseling & Psychological Services in Bankers Hill. Definitive implant-supported restorations utilize CAD/CAM-milled zirconia frameworks with hand-layered feldspathic porcelain to replicate natural translucency gradients across full-arch fixed prostheses cemented to custom titanium abutments.
