NCT05920811

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.

Outcome Measures

Primary Outcomes (3)

  • obturator functioning scale

    The Obturator Functioning Scale ( minimum value is "1"and maximum value is "5"

    6 months

  • patient outcome the treatment time, on the self-perception of the applied impression protocol in terms of general convenience, anxiety, taste, nausea sensation and possible pain sensation.

    questions focused on general convenience, anxiety, taste, nausea sensation and possible pain sensation, assessed through visual analogue scale (VAS)

    6 months

  • operator outcome

    Questions focused on the treatment time, on the self-perception of the applied impression
