Direct Restoration of the Worn Anterior Dentition: A Roadmap to the Complex Case (hands on)

Dr Jason Smithson BDS (London), DipRestDentRCS (Eng)

TBC Autumn 2025

Course Overview

Historically, Tooth Surface Loss affecting the anterior teeth was treated with full coverage restorations, often to the full mouth; although predictable and durable this approach is expensive both financially and in terms of further iatrogenic loss of tooth structure. More recently, Dahl proposed an approach whereby composite is used additively to restore worn tooth structure: this offers a less expensive, conservative solution, however, it can be somewhat unpredictable to plan and often requires multiple adjustments.

This Master class is designed to allow the experienced practitioner to confidently approach more challenging anterior cases starting with transferring information from the patient to the articulator, functionally planning the smile design and occlusal scheme on the articulator and finally accurately transferring the treatment plan back from the articulator to the patients mouth in a predictable time efficient manner.

What our delegates have been saying:

Very informative and some great tips which will very much change the way I practice.

Thank you Jason Smithson and BSOS.

Very well presented, step by step approach from structured planning to restoration.

Plenty of useful discussion within the keen group.

Fantastic hands on section. Great speaker.

Very useful course.

A good course and well presented by Jason.

A very good course which will make more precise and efficient the way in which I rebuild anterior guidance in composite.

Also made me ask questions of myself and expose learning deficits which I need to fill!

Enjoyed the presentation, especially hands-on part. Very well organised by sponsors. Thanks for providing all the equipment & materials.

Jason is a very personable & experienced presenter & willing to share his knowledge & experiences. Many thanks.
