Manual Dexterity of Patients With Bilateral Complete Maxillectomy Rehabilitated by Different Approaches (A Cross-over Study)

10 participants received 2 piece obturators connected with magnet attachment, after 3 months the magnets were replaced by dowel pins and given to the participants for a further 3 months. Patient satisfaction was assessed at the end of the 3 months' follow-up by the form of a 3-level questionnaire (not satisfied, satisfied, or very satisfied). Participants were asked about how much they are satisfied by their prostheses regarding manual dexterity, retention, and stability. The McNemer test was used for all the 3 parameters (a=.05). Patients received Standardized Chewing Test Units (SCT) to measure their chewing efficiency. It is available in three different colored consistencies: soft and hard.

Primary outcomes

  1. Patient satisfaction

    Time frame: 3 Months

    Patient satisfaction was assessed at the end of the 3 months' follow-up by the form of a 3-level questionnaire (not satisfied, satisfied, or very satisfied). Participants were asked about how much they are satisfied by their prostheses regarding manual dexterity, retention, and stability.

Secondary outcomes

  1. Chewing efficiency

    Time frame: 3 Months

    Patients will receive Standardized Chewing Test Units (SCT) from BREDENT to measure their chewing efficiency. The SCT are standard-sized, spherical, prefabricated jelly testing units. It is available in three different colored consistencies. The patients will be tested with the soft and hard consistencies. The patient's ability to cut the rounded unit into pieces is used to measure their chewing efficiency; the more pieces they can cut, the more efficient they are. Patients will be allowed to chew for 10 chewing cycles, chewing cycles will be measured with electromyography
