Board-certified periodontist and Diplomate of the American Board of Periodontology, William J. Cho, DDS, MS operates a periodontal and implant surgery practice in Carlsbad on El Camino Real. With more than 5,000 dental implants placed across single-tooth, multi-unit, and full-arch all-on-four configurations, the practice maintains a referral network that extends across North County's general-dentistry and specialty corridor, including shared-care pathways with practices such as Village Optometry for patients requiring comprehensive Carlsbad Village health coordination. Training includes a Doctor of Dental Surgery degree from USC and a three-year periodontal residency at Ohio State University, where a Master of Science in Dentistry was earned through clinical research on mechanical trauma to gingival tissue. The surgical suite is equipped with digital 3D cone-beam CT, intraoral scanning, and a chairside 3D printer that produces surgical guides, temporary prosthetics, and bone-graft scaffolds for immediate-load protocols. Post-surgical implant patients managing systemic inflammation or neuropathic discomfort coordinate adjunctive care with providers such as Aviara Acupuncture & Integrative Health in Carlsbad's Aviara district. The most complex cases involve zygomatic implant placement for severely atrophic maxillae, bypassing the need for sinus-lift bone augmentation through angled fixation into the zygoma.
