State-of-the-art Technology
Our doctors use cutting-edge technology to ensure the best possible results and to make your treatments more efficient, comfortable and minimally invasive.
Our digital X-rays are clearer, faster to produce and emit far less radiation than standard film X-rays. Our cone beam 3D CT scanner produces 3D images of your entire jaw bone and all your teeth. With these images loaded into special software, Dr. Reshad can precisely plan your implant placements and any needed bone grafting ahead of time. This makes the procedure very accurate and minimally invasive.
Our dental laser and micro-instruments are much less invasive and more precise than standard surgical instruments and are used when needed in our gum disease treatment, gum recession treatment and cosmetic gum treatments.
Our Approach to Specialized Periodontal Care
We prioritize personalized strategies over standardized protocols, tailoring our approach to your unique circumstances and objectives. As specialists in periodontics, we focus on maintaining gum health and supporting the surrounding bone. Our comprehensive diagnostics include advanced imaging and thorough clinical exams to thoroughly assess your periodontal health. We then work with you to create treatment plans that align with your clinical needs, timelines, budgets, and comfort levels.
Our minimally invasive methods ensure efficiency with minimal post-operative discomfort. Utilizing growth proteins, we enhance healing, speed recovery, and reduce pain and swelling. With over 40,000 procedures completed, our experienced team delivers exceptional results.
