The Effect Of Crowding On The Accuracy Of 3d Printed Aligners, Tonya Spangler
The Effect Of Crowding On The Accuracy Of 3d Printed Aligners, Tonya Spangler
Theses and Dissertations
Purpose: To evaluate the accuracy of three-dimensionally (3D) printed aligners compared to conventional vacuum-formed thermoplastic aligners with varying levels of dental crowding.
Methods: Digital intraoral scans of 10 different cases were assigned to their respective groups (n=10, each, 30 total) as follows: no crowding (control), moderate crowding, and severe crowding. Using 3Shape software, digital aligner samples were created in standard tessellation language (STL) file format and randomly 3D printed. The same STL files of each case were also sent to a dental laboratory for the fabrication of vacuum-formed samples, which is the current technology used for manufacturing aligners. The intaglio …
Effect Of Clear Aligner Therapy On Masticatory Muscle Tenderness And Orthodontic Pain, Johnny Tran
Effect Of Clear Aligner Therapy On Masticatory Muscle Tenderness And Orthodontic Pain, Johnny Tran
Electronic Thesis and Dissertation Repository
Introduction: Patients undergoing orthodontic clear aligner therapy (CAT) may experience discomfort in their teeth and jaws, and often present with visible wear on their aligners. This multi-site prospective clinical study aimed to analyze tooth pain and masticatory muscle tenderness in patients subjected to CAT with Invisalign©.
Methods: Twenty-seven healthy adults undergoing treatment with Invisalign© were recruited from three university-based orthodontic clinics. Tooth pain and muscle tenderness were reported on visual analog scales in pain diaries prior to, and after starting CAT. Pressure pain thresholds (PPT) measured using pressure algometers were used to assess somatosensory changes in trigeminal and extra-trigeminal locations. …
