Objective: Poor conditions in the intraoral environment often lead to low-quality photos and videos, hindering further clinical diagnosis. To restore these digital records, this study proposes a real-time interactive restoration system using segment anything model.
Methods: Intraoral digital videos, obtained from the vident-lab dataset through an intraoral camera, serve as the input for interactive restoration system.
Effect of varying auxiliaries on maxillary incisor torque control with clear aligners: A finite element analysis.
Am J Orthod Dentofacial Orthop
July 2024
Article Synopsis
- This study evaluated how different attachments (auxiliaries) affect tooth movement and stress when using clear aligners to torque maxillary central incisors by 1°.
- Five models were tested: no auxiliaries (control), power ridge, semi-ellipsoid attachment, horizontal rectangular attachment, and horizontal cylinder attachment.
- The semi-ellipsoid attachment provided better stress distribution, while the power ridge offered better root control but caused a twist in the teeth.
Objectives: Orthodontic tooth movement is a mechanobiological reaction induced by appropriate forces, including bone remodeling. The mechanosensitive Piezo channels have been shown to contribute to bone remodeling. However, information about the pathways through which Piezo channels affects osteoblasts remains limited.

- The study assessed how effective clear aligners are at controlling the torque of upper front teeth based on pre- and post-treatment scans of 47 patients.
- The results showed that the actual torque achieved was significantly lower than what was predicted, with an efficiency rate of about 46.81%.
- The findings suggest that clear aligners have difficulty managing upper-incisor torque, especially regarding root movement, which may require overcorrection to mitigate torque loss.
Runx2 and Nell-1 in dental follicle progenitor cells regulate bone remodeling and tooth eruption.
Stem Cell Res Ther
September 2022
Dental follicles are necessary for tooth eruption, surround the enamel organ and dental papilla, and regulate both the formation and resorption of alveolar bone. Dental follicle progenitor cells (DFPCs), which are stem cells found in dental follicles, differentiate into different kinds of cells that are necessary for tooth formation and eruption. Runt-related transcription factor 2 (Runx2) is a transcription factor that is essential for osteoblasts and osteoclasts differentiation, as well as bone remodeling.
