Dr. Mark S. Richey purchased Rancho Dental Group in 1996, five years after the University Avenue practice first opened, and he holds a Doctor of Dental Surgery from Northwestern University Dental School (1988) followed by a hospital-based General Practice Residency at the University of Nebraska Medical Center. That GPR background, completed by roughly five percent of dental graduates, equips the office to treat medically compromised patients whose orthodontic needs are coordinated with referrals to Milberg Orthodontics. Restorative work centers on ceramic crowns, porcelain veneers, implant-supported restorations, and bite rebuilding for patients whose occlusion has collapsed from years of grinding. Difficult root canal anatomy is referred out to specialists at Brian T. Quesnell, DDS - Mission Hills Endodontics rather than attempted in-house, which keeps single-visit failure rates down. Full-mouth bite reconstructions combine custom night-guard fabrication, selective enameloplasty, and staged crown rebuilding to restore vertical dimension lost to parafunctional wear.
