Dr. Lauren Yasuda Rainey is a proud alumna of the University of the Pacific, Arthur A. Dugoni School of Dentistry. After receiving her dental degree, she completed a General Practice Residency at Tufts University School of Dental Medicine. Her focus at Tufts was on advanced restorative techniques, including the use of surgical microscopes for restorative care, treating patients with complex medical needs and strengthening her skills by teaching in the undergraduate dental clinics.

After residency training, Dr. Rainey began teaching at the Dugoni School of Dentistry in the Department of Reconstructive Dental Sciences and the Department of Dental Practice. She was involved in both lectures and hands-on coursework in teledentistry, pre-clinical restorative curriculum, and local anesthesia administration. Dr. Rainey continues to teach direct composite restorative programs including black triangle closures, predictable class II techniques and is an advocate for using composite resin for crown alternatives wherever possible. She has taught dentists in the US and Canada, both in-person and in virtual hands-on formats. Dr. Rainey was recently featured by the Seattle Study Club in their Expert Tips series.

Dr. Rainey maintains a private practice in Berkeley, California where she developed and launched her own in-office membership program in 2018.

Episode Summary

Today we’ll explore why direct composite procedures are quickly becoming a preferred alternative to traditional indirect restorations—and how you can use hybrid techniques like deep margin elevation and model-based composite crowns to deliver exceptional results without prepping away valuable tooth structure or sending cases to the lab. Joining us are two experienced clinicians, Dr Lauren Rainey and Dr Mauricio Watanabe. They will share how the use of highly filled nanocomposite materials in their techniques are transforming the way they restore teeth—and why patients are loving the results.
