FAQs from Orthodontists

1. What is the role played by the CAD-CAM in Orthodontic Treatment?
CAD, the computer-aided design, represents the creation process of a technical drawing using the computer software. The computer system is used to help create, modify, analyze, or optimize a design.

The application of CAD software has boosted the designer's working efficiency, bettered the design quality, and improved communications through documentation (namely the communications with orthodontist in terms of teeth setup and the bracket design). Meanwhile, the database needed for manufacturing come into being. In addition, the CAM is the abbreviation of computer-aided manufacturing.

2. Can we achieve the same results by positioning the bracket with our eye or by laboratory procedures, such as transfer tray?
Yes. Since lingual orthodontic treatment is an extremely complicated process and the tooth structure is subject to change, the arch wires with a few bends will be in need. The CAD and CAM technologies enable us to achieve a more precise setup, a more individualized treatment plan and, most importantly, accurate arch wires.

3. Why choose eBrace?
The eBrace is fabricated using the advanced CAD and CAM techniques. The bracket can be manufactured from three materials including nickel chrome alloy, cobalt-chromium alloy as well as gold alloy for orthodontists to choose.

Various kinds of arch wires are pre-bended, electronic setup model is provided and the designed picture of bracket detail is sent to the orthodontist. We will communicate with the orthodontist. Above all, the eBrace is reasonably priced and manufactured in a shorter time, making the period from impression taking to bonding being shortened dramatically.

4. How to make the treatment plan with e-Brace?
Since all the arch wires are already bended before treatment, the treatment plan should be described to the laboratory workers carefully.

In the case of extractions, the doctor should ask for straight wires at extraction site so that sliding will be possible. Once space is closed, the last arch wire should be changed for precise adjustment of the position of the teeth, including both inset and offset of molar and premolar.

If stripping is planned, it is important to decide where and when the stripping will be performed. Brackets' size should conform to the IPR plan. Furthermore, wires should be bent in a way that the teeth can move to the site of the stripping and the gap resulting from the stripping can be closed. Too many bends around the teeth may block the teeth from movement.

One of the difficulties in lingual orthodontic treatment is the rotation of teeth, due to the small inter-bracket distance. Doctors can design the brackets in crowded areas in a way that will make rotations easier. Accessories like rotation ties or lingual buttons can help accomplish the de-rotation in a short time and then eBrace arch wire will play its role in a better and faster way.

The pre-made eBrace arch wires are designed to correct the torque in the most precise way. Yet, the customized bracket is very small but can fix the arch wire into the slot with the metal ligature. If extra torque is needed (like in Class II distoclusion, division 2), the doctor can request a few wires to correct the torque slowly instead of one arch wire because sometimes it is impossible for one arch wire to be inserted into the slot.

5. Can eBrace bring us miracles?
Definitely not! The system is designed to give the doctor freedom in prescribing different brackets, customized arch wires, design of accessories like hooks and anchorage tools. The doctor needs to spend time in planning the treatment and instructing the technician to transform the ideal orthodontic plan into the individualized appliance. No technician is able to take over the doctor's part. The better the communication with the technician is, the better the end result will be.
