Aesthetic Diagnostic Wax-Up of Anterior Teeth with DVO Increase

Introduction: In addition to being a method of communication between the intervenients of an oral rehabilitation, the diagnostic wax-up (DW) is a helper when it proves necessary to change the vertical dimension of occlusion (VDO). Objective/Methods: This clinical review intends to evaluate the parameters achieved by the execution of a DW in aesthetic rehabilitations in the anterior teeth with DVO increase. Bibliographic research was performed on PubMed/Medline with the key-words: "wax-up AND DVO", "diagnostic wax-up" and "anterior dental aesthetics". Systematic reviews, narrative reviews and clinical cases, published in the last 10 years, were included. Results: 14 publications meet the inclusion criteria. There are several DW techniques, including the progressive one. In the presence of large dental destruction with DVO increased, DW restores the worn portion of teeth, looking to determine the correct occlusion plane, balanced simultaneous posterior contacts and the anterior guide. From the DW is possible to acquire mock-ups, temporary or permanent restorations, as well as guides that present themselves as auxiliaries in rehabilitation. Conclusions: Planning through study casts articulated in centric relation with DW execution makes it possible to determine details that aid rehabilitations that need DVO increase. Clinical implications: In rehabilitations that include accentuated aesthetic and functional changes, among them the DVO increase, DW is a process that ensures a better predictability of results.
