In prosthetic and orthotic applications, 3D scanning and digital modeling technologies are increasingly used in the measurement and design stages. This article gives a general overview of how these technologies are used in the production process. The general contributions of the technology to the orthotics and prosthetics field are discussed under a separate heading.
3D measurement (scanning)
As an alternative to the traditional plaster cast method, a surface measurement of the relevant body area can be taken with the help of digital scanners. The notable aspects of this method are:
- Measurement can be carried out without contact or with minimal contact.
- The procedure can usually be completed in a shorter time.
- Mess associated with the use of plaster is reduced.
- The data obtained can be stored digitally.
Digital modeling
The scanned data is transferred to a computer and modeled. At this stage, precise adjustments can be made to the anatomical positioning of the limb. The aim is to design the device to fit the person's anatomy; this approach is one of the basic steps of custom-made production in orthotic and prosthetic technology. The modeling process is carried out in line with the physician's report and specialist assessment.
Production stage
Once the digital model is prepared, production of the device is planned. The fit of the produced prosthesis or orthosis for the person is assessed, together with the selected materials, through trial and fitting sessions. Any necessary corrections can be made again on the digital data.
All of these applications are carried out by authorized healthcare professionals in the field, in line with the specialist physician's prescription and medical report. The appropriate solution for the person is determined as a result of an individual assessment.
