Increasing occlusal vertical dimension - Why, when and how

Key Points Correct diagnosis and treatment planning is crucial. A diagnostic wax up is essential to allow conservative preparation and prototype fabrication and thus verifying any change in the occlusal scheme. A thorough understanding of occlusion is essential for any rehabilitation case be it functional or aesthetic. Changes in vertical dimension can allow for more conservative dental rehabilitations. All porcelain resin bonded restorations can be a conservative treatment modality for increasing vertical dimension. Key Points Aesthetics and cosmetics Aesthetic changes with four anterior units Smile lifts - a functional and aesthetic perspective Increasing occlusal vertical dimension - why, when and how Cosmetic dentistry has evolved with the advent of more robust porcelain materials and ever-stronger bonding agents. This series of three articles aims to provide a practical overview of what is now possible both functionally and cosmetically from the preparation of a small number of teeth, through a whole smile, to full mouth rehabilitation. A complete diagnosis is the starting point to planning any cosmetic or functional changes. Guidance is given on the techniques used but adequate training must be considered essential before embarking upon modification in occlusal schemes or even minor adjustments in smile design. Understanding vertical dimension and how and when it can be changed has always been a challenging prospect for the general dental practitioner. This article aims to discuss the rationale behind changes in vertical dimension and demonstrate how it can be achieved in general practice assuming adequate hands-on postgraduate training has been completed.
