Why Choose Us

Choosing a periodontist in Mission Viejo, CA, requires careful consideration, especially when dealing with complex gum and implant needs. At OC Perio & Implants Dental Group, we distinguish ourselves through specialized expertise, advanced technology, and a patient-centered approach. Here’s why we’re your ideal choice:

50 Years of Excellence

Our practice was the very first periodontal practice to open in Mission Viejo, founded by Dr. Robert Hirst in 1976 after his service in the US Navy Dental Corps. Dr. Ajay Setya joined Dr. Hirst and took ownership of the practice in 1997. For nearly five decades, we have built a legacy of trusted, specialty-level care for the residents of South Orange County. Today, Dr. Setya, Dr. Reshad, and Dr. Christen Bergman carry that tradition forward, providing expert, comprehensive periodontal and implant services rooted in 50 years of clinical excellence.


Specialists in Periodontics and Prosthodontics

We are a true specialty practice. Our doctors focus exclusively on the gums, bone, and supporting structures around your teeth, as well as the restorative side of dental implants and full-mouth reconstruction. This combined expertise in periodontics and prosthodontics means your surgical care and your final tooth replacement are planned together from day one, giving you a more predictable result and a healthier, longer-lasting smile.

Dr. Setya is a recognized expert in dental implants and holds numerous advanced certifications in implantology. He teaches advanced implant procedures and comprehensive periodontics to other practitioners at seminars throughout the U.S. and internationally.


Dedicated Specialty Care

Because we limit our practice to periodontics, prosthodontics, and dental implants, every case we see receives the focused attention of a specialist. We are not a general dental office that occasionally performs gum or implant procedures — this is what we do every day. Patients are referred to us for the most complex cases in the region, and that depth of experience translates directly into better outcomes for you.


Highest Quality Materials Available Worldwide

We never cut corners on the components that go inside your mouth. Our practice sources the highest quality implants, grafting materials, membranes, and restorative components available worldwide. From premium titanium and zirconia implant systems to advanced biologics that support faster, healthier healing, the materials we use are chosen for long-term performance, biocompatibility, and proven clinical outcomes.


A Strong Team and a Caring, Patient-Focused Environment

At OC Perio & Implants, our team works together to deliver state-of-the-art care in a warm and welcoming environment. Our staff is dedicated to making your visits efficient and comfortable, while our doctors take the time to listen to your concerns and thoroughly explain every procedure. Dr. Setya, Dr. Reshad, and Dr. Bergman believe that informed patients are confident patients, and we want you to feel completely at ease throughout your time with us.


Minimally Invasive Procedures — Including Perioscopy

We use cutting-edge technology to make your treatments more efficient, comfortable, and minimally invasive:

  • Digital X-rays are clearer, faster, and emit far less radiation than standard film
  • Cone beam 3D CT imaging that allows Dr. Setya to precisely plan implant placement and bone grafting before the procedure begins
  • Dental lasers and micro-instruments that are more precise and less invasive than traditional surgical tools
  • Perioscopy — a minimally invasive technology that allows us to visualize and treat deep periodontal pockets without traditional gum surgery

We are proudly the only practice in the area offering Perioscopy in Irvine, providing our patients with a more comfortable, less invasive option for treating advanced gum disease.


Customized Treatment Plans Tailored to Each Patient

No two mouths are the same, and no two treatment plans should be either. We take the time to fully evaluate your oral health, medical history, goals, and budget before recommending any treatment. You will receive a clear, written plan with all of your options explained, so you can make confident, informed decisions about your care.


Expertise in Correcting Implant Complications and Complex Cases

When implants fail, become infected, or are placed improperly, patients across Orange County are referred to our office for help. Dr. Setya has extensive experience correcting implant complications, managing peri-implantitis, performing bone regeneration around failing implants, and rebuilding cases that other offices were unable to complete. If you have been told your case is too complicated, we encourage you to come see us for a thorough evaluation.


Second Opinions Available

We understand how important it is to feel certain about your dental care. If you have been given a treatment recommendation elsewhere and want another perspective, we offer second opinions. Our specialists will carefully review your case and provide straightforward, expert guidance so you can move forward with confidence.
