Board-certified by the American Board of Oral and Maxillofacial Surgery, Randall Stettler runs the veteran-owned Grossmont Oral Surgery Center in La Mesa near Grossmont Center. The AAAHC-accredited facility coordinates surgical-guide and prosthetic-component fabrication through dental laboratories including Sharp Detail Orthodontic Lab, ensuring sub-millimeter precision for implant fixture angulation and placement depth. A University of Missouri-Kansas City dental degree followed by oral-surgery residency training at Walter Reed Army Medical Center preceded a military career reaching the rank of Lieutenant Colonel, with tours as Chief of Oral and Maxillofacial Surgery in Seoul, Korea, and at Fort Carson, Colorado. The Grossmont Center Drive practice established its civilian operation in 2002 after military retirement and performs emergency facial-trauma reconstruction under referral from Sharp Grossmont Hospital's emergency department. Post-surgical jaw-rehabilitation cases route to Grossmont Post Acute Care for recovery-phase physical therapy, completing the maxillofacial treatment cycle from surgical intervention through functional restoration. Highest-complexity procedures include immediate-load All-on-4 implant placement with simultaneous alveoloplasty and guided bone regeneration using titanium-mesh frameworks for patients presenting severe maxillary or mandibular atrophy.
