Yi Luo DDS-Pleasanton Prosthodontist
When it comes to science, one of Dr. Luo’s many accomplishments is that she has published numerous articles. The most recent of which studies dental implant risk factors. Out of this collaborative study, she and her colleagues developed an online interactive risk assessment that lets people learn about their risk factors for dental implant treatment. Feel free to take the assessment at www.mydentalrisk.com and to ask Dr. Luo about it.
Dr. Luo Joined Pleasanton Prosthodontics in 2020. Dr. Chao and Dr. Luo hit it off immediately when they started talking 3D dentistry. Patients have taken to Dr. Luo also-not only is she good with her hands, She is a technology whiz and kind hearted to boot!
Personally, Dr. Luo grew up in Beijing, China and she studied Stomatology at Peking University. She and her husband are new parents and are enjoying the adventure of raising their son here in Pleasanton. Please come by to meet Dr. Luo if you haven’t already!
