This case has been a work in progress for a number of weeks. Anterior cases are somewhat challenging but with patience and a good lab to work with, the esthetic end result is predictable. A true team effort from start to finish. Thank you for all your help. Replacing the left anterior bridge is next on the list. ❤️🦷🪥 😀

2024 has been a year where we went back in time to get acquainted with the dentistry that got us here decades ago. Thanks to .dental.education .chrysalis.genesis.bt and Dr. Brian Fruend for the incredible learning experience. We spent a few days learning about complex extractions, suturing techniques and dealing with complications that could arise during procedures. Our confidence in tackling surgical procedures has soared!

Happy we were able to reframe the diplomas this week. Thank you to Adina for doing such a beautiful job. A few of the frames were decades old and a refresh has been in the works for a while.

My morning started as peacefully as my day ended. The mayhem in between has long been forgotten.
