Investigating the Longevity of Implant Protected Occlusion Utilizing the T Scan III: A Prospective Study
Abstract
To investigate the longevity of Implant Protected Occlusion utilizing the Tekscan III. Materials and Methods: The study was approved at the Washington, D.C. Veteran Affairs Medical Center Dental Service. Patient inclusion criteria consisted of a single tooth endosteal implant bounded by natural teeth and opposed by natural dentition. At initial time of delivery of the prosthesis the occlusal scheme was be verified clinically by the restoring dentist. This result was confirmed using the Tekscan III to measure occlusal force distribution percentage at maximum intercuspation. The analysis included the patient to return and for the evaluation to be reviewed again at 6,9 and 12 months. The force distribution exerted on the implant retained restoration was then compared to the initial delivery appointment. Results: A total data set of 14 subjects with 16 implants was collected. Only 9 subjects fulfilled the entire inclusion criteria. The mean bite force of natural teeth was 10.4 percent versus the mean bite force in the selected implants was 2.2 percent. Conclusions: If Implant protected occlusion remains relatively stable over time is still unclear at this time. Data at this interim analysis does not show a significant difference in implant protected occlusion. Despite the implant protected planned occlusal scheme restoring dentists did not always achieve the desired results. Some statistically insignificant p- values were calculated but found to be irrelevant due to the low power of the study. A better understanding of all implant occlusion would allow clinicians to take a more preventive approach when performing implant treatment planning, as avoidance of implant overloading helps to ensure the long-term stability of implant restorations.
