is it possible to increase a decreased vertical dimension(for example : due to attrition )using only fixed prosthetics & related processes (reduction - imprression - restoration construction & insertion ) ?
First you have to increase vertical dimensions using a diagnostic occlusal splint. increase has to come in increments and see the response of the patient towards increasing occlusal treatment. Meanwhile if you have to change occlusal scheme also then better to provide an occlusal splint having the designed occlusal scheme. the patient wears the occlusal splint for a period of 3 months - check response - the highest amount of increase that brings unfavorable changes will be a guide to the amount of increase that can be incorporated.
yes with effective temporarization in between for conditioning of patient you can increase the vertical dimension, occlusal precision needs to be achieved with an Arcon type semi adjustable articulators.
