ToothInpaintor: Tooth Inpainting from Partial 3D Dental Model and 2D Panoramic Image [PDF]
arXiv, 2022 In orthodontic treatment, a full tooth model consisting of both the crown and root is indispensable in making the treatment plan. However, acquiring tooth root information to obtain the full tooth model from CBCT images is sometimes restricted due to the massive radiation of CBCT scanning. Thus, reconstructing the full tooth shape from the ready-to-use

Exploring developmental changes in femoral midneck cross‐sectional properties
The Anatomical Record, EarlyView.The properties of femoral midneck cross‐sections exhibit a unique growth pattern that is characterized by shape changes during adolescence. Abstract This research delves deeper into previous works on femoral cross‐sectional properties during ontogeny by focusing for the first time on the human femoral midneck. The ontogenetic pattern of cross‐sectional

Mandibular Teeth Movement Variations in Tipping Scenario: A Finite Element Study on Several Patients [PDF]
arXiv, 2020 Previous studies on computational modeling of tooth movement in orthodontic treatments are limited to a single model and fail in generalizing the simulation results to other patients. To this end, we consider multiple patients and focus on tooth movement variations under the identical load and boundary conditions both for intra- and inter-patient ...

Ammonia-Net: A Multi-task Joint Learning Model for Multi-class Segmentation and Classification in Tooth-marked Tongue Diagnosis [PDF]
arXiv, 2023 In Traditional Chinese Medicine, the tooth marks on the tongue, stemming from prolonged dental pressure, serve as a crucial indicator for assessing qi (yang) deficiency, which is intrinsically linked to visceral health. Manual diagnosis of tooth-marked tongue solely relies on experience.

The Anatomical Record, EarlyView.Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Automatic Tooth Arrangement with Joint Features of Point and Mesh Representations via Diffusion Probabilistic Models [PDF]
arXiv, 2023 Tooth arrangement is a crucial step in orthodontics treatment, in which aligning teeth could improve overall well-being, enhance facial aesthetics, and boost self-confidence. To improve the efficiency of tooth arrangement and minimize errors associated with unreasonable designs by inexperienced practitioners, some deep learning-based tooth arrangement ...

Shaping the human face: Periosteal bone modeling across ontogeny
The Anatomical Record, EarlyView.Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.
