Adding a Tooth to a Metal Framework Obturator using CAD/CAM Technology

The ramifications of tooth loss after obturator fabrication can present a challenging situation in which there are limited viable solutions. This challenge is only amplified by poor masticatory ability, a change in phonetics, and esthetic concerns that can negatively affect a patient’s psychological and social wellbeing. Replacement of a missing tooth can be accomplished through fixed, repairing or refabricating the removable obturator prosthesis. Although fixed options tend to be the choice of treatment, removable prosthetics can often be the treatment of choice when the edentulous area is too long, surgery is not an option for implants, or a patient’s finances or desires necessitate an alternative to fixed prosthodontics. This article introduces a novel technique to add a tooth to a metal framework obturator utilizing CAD/CAM technology. A patient presented to a prosthodontic practice with a maxillary obturator and a missing maxillary central incisor. The obturator was well-fitting, and the patient was highly satisfied with the obturator but wanted to replace his missing maxillary central incisor which was lost due to loss of periodontal support. An abutment was designed and cast in ticonium; it was then soldered to the metal framework. A lithium disilicate ceramic crown was milled and cemented to the abutment to replace the missing tooth.
