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.

Tongue and Occlusal Pressure Performance and Dietary Habits in Maxillectomy Patients With Obturator Prostheses

This study investigates mouth cancer patients who use a special plate called an obturator to help them swallow. Tongue strength and biting force will be measured and compared to daily dietary intake. Results will provide a better understanding of how to improve eating ability and overall quality of life.

Comparison of Conventional and 3D-printed Surgical Obturators for Maxillary Defects

This randomized controlled clinical trial aims to compare patient satisfaction and prosthetic complications associated with three types of immediate surgical obturators used in maxillectomy patients. A total of 24 patients with acquired maxillary defects will be randomly assigned to receive one of three obturator designs: (1) conventional obturators retained with clasps and wire, (2) resin 3D-printed obturators with printed clasps and palatal screws, or (3) metallic 3D-printed obturators with metal clasps and palatal screws. Patient satisfaction will be evaluated using the Obturator Functioning Scale (OFS), and postoperative complications such as discomfort, lack of retention, or mucosal irritation . The study seeks to determine whether digital fabrication and enhanced retention methods improve clinical outcomes compared to traditional approaches
