Tooth/Teeth Segmentation and modeling from X-ray/CT images: A Survey
نویسندگان
چکیده
Segmentation of tooth/teeth from dental computed tomography (CT) or X-ray images and thereby its 3D visualization is of great significance for computed assistance strategies such as anomalies detection, planning for orthodontics, dental implants, face and jaw surgeries and much more. This application is often used in forensic science for human identification using matching of post-mortem (PM) and antemortem (AM) dental scans, lesions detection and few others. Some of these applications require isolation of tooth and thereby its critical examination using 3D visualization. The aim of this paper is to discuss various approaches proposed so far by different researchers for segmentation and modeling of the tooth from CT images. It also discusses various challenges in the field of orthodontics and different ways to overcome them.

A Hybrid Method for Segmentation and Visualization of Teeth in Multi-Slice CT scan Images
Introduction: Various computer assisted medical procedures such as dental implant, orthodontic planning, face, jaw and cosmetic surgeries require automatic quantification and volumetric visualization of teeth. In this regard, segmentation is a major step. Material and Methods: In this paper, inspired by our previous experiences and considering the anatomical knowledge of teeth and jaws, we prop...

In the dental field, 3D tooth modeling, in which each tooth can be manipulated individually, is an essential component of the simulation of orthodontic surgery and treatment. However, in dental computerized tomography slices teeth are located closely together or inside alveolar bone having an intensity similar to that of teeth. This makes it difficult to individually segment a tooth before buil...
متن کاملPerformance Evaluation on Segmentation of Dental CT Images for Individual Recognition
The purpose of programmed dental segmentation is to identify the person based on dental computed tomography (CT) images. Teeth play important key role in forensic dentistry. We segment the teeth image. The segmentation process consists of Otsu thresholding, morphological processing, orthogonal lines and volume of interest (VOI). In this paper, a segmented tooth is useful for the feature extract...
متن کاملTooth Segmentation From Cone-Beam CT Using Graph Cut
Cone beam computed tomography (CBCT) can provide dentists with accurate 3D diagnostic images of the maxillofacial region at a lower irradiation dose compare to conventional medical CT. Due to low image contrast, higher image noise and missing image boundaries, tooth segmentation in CBCT is difficult even with experienced radiographic interpreters. In this paper, we proposed a graph cuts segment...

To find borders between homogeneous regions in the various morphologies, several segmentation resulting from edge-based and region-growing can not produce exactly the same, and a combination of results often work more accurately. Also, clinically usable segmentation for medical imaging requires a high degree of interaction with registration algorithms such as the Insight Toolkit (ITK) and the V...
