OHI-S Fixed Prosthetic Restorations common mistakes and advanced solutions

4 lessons + 1 free (4h 23min)

Fixed prosthetic treatment — a complex process where mistakes are inevitable. However, not all doctors are willing to openly acknowledge and discuss this issue.

We invite you to a unique course where renowned speakers will share their personal stories of success and failures in fixed prosthetic restorations, emphasizing the importance of learning from mistakes.

On this course, you will learn about the main mistakes:

– In diagnostics and treatment planning

– During preparation

– When taking an impression

– In adhesive fixation.

Join our course and learn how to prevent clinical errors, save time and resources, and most importantly, provide maximum comfort and quality treatment for your patients!

The OHI‑S Fixed Prosthetic Restorations: Common Mistakes and Advanced Solutions course is best for prosthodontists, restorative dentists, and dental technicians who want structured, training in identifying pitfalls and applying advanced corrective strategies in fixed prosthetics. It emphasizes evidence‑based workflows to avoid errors and ensure long‑term functional and aesthetic success.
