Introduction: Dental implants are one of the top 3 reasons to sue a dentist for malpractice. It involves dental implant complications, usually because of the angle of the implant installation from the surgery. In the present, surgeons commonly use a 3D printed surgery navigator that is customized for the patient’s oral structure to prevent such malpractices. However, they can be expensive and time consuming since those navigators are customized for specific individual patients. Surgeons will not be able to reuse any of the devices and will need to create a new one every time when there is a new patient. Moreover, as the devices cannot be reused, it can affect the environment as well since the used ones must be disposed of. Therefore, I made an implant operation guiding device that would be cheaper, can be generally used, and also easy to use.
Materials and
Methods: Since a problem associated with the angle of the implant can lead to complications, the device will focus on the orientation of the handpiece. The surgeon can input the angular objective of the operation, and the device constantly checks if the surgery is heading towards the objective within the set range, notifying the surgeon by manipulating the LED. I tested the prototypes’ consistency and accuracy by checking the graph of the calculated angular values, average standard deviation, and the average rate of change of the calculated angles. The accuracy of performance was also acquired by running the device and checking the outputs.
Results, Conclusions, and Discussions: The first prototype used both of the accelerometer and gyroscope sensors from the Arduino MPU6050 sensor. It got a changeable graph, achieving 0.0295 of standard deviation, 0.25 of average change, and 66.6% accuracy of performance. The second prototype used only the gyroscope, and it got a constant graph, achieved 0.0062 of standard deviation, 0.075 of average change, and 100% accuracy of performance, indicating that the accelerometer sensor aggravated the functionality of the device. Using only the gyroscope sensor allowed it to measure the orientations of separate axes without affecting each other and also increase the stability and accuracy of the measurements.
