Increase of Vertical Dimension of Occlusion (VDO) with Temporary CB Resin in a Complex Rehabilitation Case

In this paper, Dr. Antonio Busato and dental technician Luca Giovenzana give a step-by-step overview of the digital process to plan and produce provisional restorations in a complex rehabilitation case with loss of vertical dimension of occlusion using CAD/CAM technology.

The introduction of new technologies in the dental field, such as 3D printing, are setting new standards of care. Digital data collection technology, including intraoral scanning, facial scans, and clinical photography, are enabling more accurate patient models than traditional methods.. This allows clinicians and dental laboratories to integrate the intraoral clinical situation with extraoral facial data to perform more precise occlusal analysis and production of restorations or prosthetics. This is especially critical for cases that require extensive oral reconstruction where form, function and esthetics are altered.

Moreover, 3D printing technology and materials provide highly customizable treatment options for complex cases where temporization is key to testing and preserving a new Vertical Dimension of Occlusion (VDO), esthetics, function before receiving permanent restorations. Accurate restorations can be effectively fabricated via 3D printing and materials have been developed for these purposes. Temporary CB Resin is a material that contains ceramic fillers providing excellent polishability, esthetics, low plaque retention and optimal mechanical properties that maintains the VDO unaltered throughout the adaptation process to this new clinical scenario.

This clinical case shows the rehabilitation process of a patient with extensive wear and loss of VDO using CAD/CAM workflows. Patient registration was done via intraoral and facial scan in the dental practice. The data was combined and restorations were planned and designed via CAD software in the dental lab. Finally, these were produced in the dental laboratory with Formlabs’ Form 3B and Temporary CB Resin and sent back to the dental practice for cementation.

Case Presentation and Diagnosis

A female patient of 52 years old sought care at the practice to address esthetic and functional deficiencies.
