Dental implants near Walnut
Placed and restored in one office
Dr. Chon, a general dentist, places and restores dental implants in-house at the Diamond Bar office, so Walnut patients are not referred out for the surgery or the crown. Each implant is $1,990 — the implant, abutment and crown — when Dr. Chon's exam and 3D scan confirm you're a candidate. If your case needs anything more, you get an itemized written price at your free consultation before anything begins. See how dental implant treatment works, from the free consultation and 3D scan to the final crown.
