Dr. Guzmán-Armstrong and Dr. MaiaDr. Sandra Guzmán-Armstrong and Dr. Rodrigo Rocha Maia present February 8 Spring Live Distance Continuing Education Course - Creating Natural Smiles with Minimally Invasive Dentistry

  • Providing patients with excellence in direct esthetic restorations can be quite challenging and time consuming in daily clinical practice. By integrating a modern approach to caries management with the scientific advances in dental adhesives and restorative materials, dental professionals can provide conservative, functional and esthetic treatment to fit the individual needs of patients.
  • The purpose of this course is to present direct esthetic restorative options based on a minimally invasive approach. Principles, materials and clinical techniques will be outlined to help the dentist and the team to achieve excellent esthetics, function and affordable solutions while preserving natural tooth structure./li>
