Description
In implant surgery, a good linear guiding accuracy can be realized by static template, but it is still less than 1mm. Such accuracy, not as high as expected, can be attributed to the lack of physical measurement during the surgery. Physical measurement is an effective way to manage the implant error within the acceptable limits. Although periodontal probe is wildly used, it is not an appropriate measuring tool for implant surgery which requires accuracy less than 1mm. In order to ensure the implant accuracy, it is necessary to measure and check the crown-root ratio and angle of implants as well as the distance between implants and adjacent teeth by special measuring tools with less-than-1mm accuracy at each interoperative step. This presentation will review the evolution of the guiding methods of implant surgery and the accuracy of these methods, and elaborate on the significance and principle of interoperative physical-measurement through clinical cases.
Upon completion of this presentation, participants should be able to: 1) identify the significance and advantages of physical-measurement in implant prosthodontics; 2) describe the principle and protocol of physical-measurement in implant surgery; and 3)
explain the clinical pathway of interoperative physical-measurement.
