Vertical Errors – Arch wire/ bracket slot relationship: Direct Customization Revisited.
Direct customisation on malocclusion cast has the advantage of being self-sufficient (non-dependent on the laboratories). Issue with direct customisation is the vertical error caused on the lingual bracket positioning because of anatomical variations of labial surfaces of teeth and inter tooth differential torque. Play in the arch wire and bracket slot is also another important factor to decide the final outcome especially when the pretreatment condition has large inter tooth discrepancies. This presentation is a critical evaluation of above factors and discussion about the solution.
