Brief summary
Evidence regarding the performance of digital obturators totally fabricated using 3D printing is insufficient. This prospective randomized crossover study aimed to evaluate patient satisfaction with conventional maxillary obturator and totally full digitally fabricated obturator. Patient satisfaction was evaluated using two scales: The Obturator Functioning Scale and The Patient and operator-centered outcomes were assessed through two visual analog scale (VAS) questionnaires.
Detailed description
The use of digital technologies in the fabrication of maxillofacial prostheses has been described. Additive manufacturing offers a more convenient and more efficient process with reduced material waste compared with traditional subtractive technique. Although Prosthetic rehabilitation with Conventional maxillary obturator prosthesis fabricated with a casted metal framework using, heat-cured acrylic resin can restore oral function and facial esthetics following maxillectomy. But it is time-consuming and labor-intensive. Multiple sources of errors can accumulate during the laboratory steps, resulting in a misfit of the framework. In this study All patients received a conventional obturator for 6 months, after a washout period of one week, they use the digital one. The Obturator Functioning Scale and The Patient and operator-centered outcomes were assessed through two visual analog scale (VAS) questionnaires.
