Missing Lateral Incisors: Beyond Space Closure

with Dr Nour E Tarraf

Abstract

Missing lateral incisors present a unique challenge for orthodontists. As they are usually diagnosed in children, closing the lateral incisor spaces can avoid compelling the child to a lifelong commitment to prosthetic dentistry. However, the results were often criticised for producing unnatural or imperfect looking smiles.

With the introduction of TADS, the anchorage challenge in closing spaces for missing laterals has been largely resolved. Yet there are still some aesthetic short comings.

This lecture will address some of the reasons for considering space closure for ALL children with missing lateral incisors. I will explore some the available skeletal anchorage set-ups to achieve predictable results and will challenge some old beliefs regarding space closure being contraindicated in cases with a Class III skeletal pattern.

I will also show some novel appliance designs and biomechanical concepts that can help us deliver a natural and full smile in cases with missing lateral incisors.
