Official title
Bone Metabolism in Patients Treated With 3d Printed Aligners Versus Thermoformed Aligners (Randomized Controlled Clinical Trial)
Overview
Background: Orthodontic forces induce tissue reactions by triggering perturbations from orthodontic appliances, which lead to the modelling and remodelling of alveolar bone. Despite the growing popularity of 3D-printed aligners, no studies have compared their effects on bone metabolism in comparison with thermoformed aligners. Aim: This study aims to assess bone metabolism in patients undergoing treatment with 3D-printed aligners versus thermoformed aligners.
Interventions
- Other Directly printed aligners using Tera Harz TA28 resin
Aligners will be digitally designed using the latest version of ArchForm software for segmentation of dental arches, virtual tooth movement planning and generation of sequential treatment stages, the finalized setups will be exported as STL files. - Other PETG thermoplastic sheets
Aligners were digitally designed using the latest version of ArchForm software .The 3D-printed resin models which were used as a mold for aligner thermoforming, were fabricated by Anycubic Photon Mono M5s (12K resolution) (Anycubic, China) 3D printing machine.
Primary outcome measures
- change in levels of Osteoprotegerin (OPG) [Time frame: up to 21 days]
Secondary outcome measures (3)
- change in gingival inflammation [Time frame: up to 21 days]
- change in plaque accumulation [Time frame: up to 21 days]
- change in bleeding on probing [Time frame: up to 21 days]
