Current Products and Practices

Abstract

Part I of this paper describes the background, general concepts, available techniques and the clinical applications of recording external craniofacial morphology in three dimensions. Part II explores the different 3D techniques of imaging the dental arches, and their possible uses in orthodontic diagnosis and treatment.

The use of three-dimensional cephalometric references in dentoskeletal symmetry diagnosis

“…- 30 , 39 Methods may have to be adapted to CBCT risks and benefits, as well as to its three-dimensional scans so as to increase the accuracy of cephalometric measurements.…”

Photographic protocol for image acquisition in craniofacial microsomia

“…In addition to obvious signs of facial tension or emotional expressions, photographers should pay attention to the subject's mouth and eyes [20-22]. The subject's mouth should be closed during capture, with the lips gently pressed together.…”

Single‐Tooth Modeling for 3D Dental Model

“…With advances in computer and optical technology, the dental cast can be digitized through various scanning techniques [1–6]. The 3D dental model can benefit CAD/CAM dentistry in accuracy, efficiency, and ease of measurement of tooth size, arch form, and its dimensions.…”

“…As the 3D (three dimensional) dental model can be acquired easily through different kinds of intra or extra oral measurement methods including optical digitizers [1–3], CT (CBCT) [4, 5] and MRI [6], CAD (Computer-Aided Design)/CAM (Computer-Aided Manufacturing) has been introduced to dentistry and achieved great success in clinical applications [7–10] such as orthodontics, oral and maxillofacial surgery. Dental restorations can be designed and manufactured much more easily compared with traditional complex and labor-intensive process.…”
