Computational Orthodontic Force Simulation: A Review [PDF]

arXiv
In orthodontic treatment, the biological response of the tooth, periodontal ligament, and bone complex to orthodontic force is crucial in influencing treatment outcomes. The challenge lies in accurately measuring, estimating, and predicting these forces during clinical procedures.

Using Natural Language Processing to Develop an Automated Orthodontic Diagnostic System [PDF]

arXiv, 2019
We work on the task of automatically designing a treatment plan from the findings included in the medical certificate written by the dentist. To develop an artificial intelligence system that deals with free-form certificates written by dentists, we annotate the findings and utilized the natural language processing approach.

Is miniscrew primary stability influenced by bone density?

Brazilian Oral Research, 2011
Primary stability is absence of mobility in the bone bed after mini-implant placement and depends on bone quality among other factors. Bone quality is a subjective term frequently considered as bone density.

Aligner-induced tooth movements in three dimensions using clinical data of two patients [PDF]

arXiv
The effectiveness of a series of optically transparent aligners for orthodontic treatments depends on the anchoring of each tooth. In contrast with roots, the crowns' positions and orientations are measurable with intraoral scans, thus avoiding any X-ray dose.

Mapping finite-fault slip with spatial correlation between seismicity and point-source Coulomb failure stress change [PDF]

arXiv
Most earthquake energy release arises during fault slip many kilometers below the Earth's surface. Understanding earthquakes and their hazard requires mapping the geometry and distribution of this slip. Such finite-fault maps are typically derived from surface phenomena, such as seismic and geodetic ground motions.

The Relationship of Various Arch Forms and Cortical Bone Thickness

Frontiers in Dentistry, 2011
Objective: Implants are being used in orthodontics as a reliable mode of anchorage. Among other factors, the cortical bone thickness plays a major role in determining the stability of these implants.

Class II malocclusion with accentuated occlusal plane inclination corrected with miniplate: a case report

Dental Press Journal of Orthodontics
Introduction: A canted occlusal plane presents an unesthetic element of the smile. The correction of this asymmetry has been typically considered difficult by orthodontists, as it requires complex mechanics and may sometimes even require orthognathic ...

Transformation trees -- documentation of multimodal image registration [PDF]

arXiv
Multimodal image registration plays a key role in creating digital patient models by combining data from different imaging techniques into a single coordinate system. This process often involves multiple sequential and interconnected transformations, which must be well-documented to ensure transparency and reproducibility. In this paper, we propose the

Orthodontic camouflage of skeletal Class III malocclusion with miniplate: a case report

Dental Press Journal of Orthodontics
Introduction: Skeletal Class III malocclusion is often referred for orthodontic treatment combined with orthognathic surgery. However, with the aid of miniplates, some moderate discrepancies become feasible to be treated without surgery.

Evaluating the Suitability of Different Intraoral Scan Resolutions for Deep Learning-Based Tooth Segmentation [PDF]

arXiv
Intraoral scans are widely used in digital dentistry for tasks such as dental restoration, treatment planning, and orthodontic procedures. These scans contain detailed topological information, but manual annotation of these scans remains a time-consuming task. Deep learning-based methods have been developed to automate tasks such as tooth segmentation.
