Course CDE Survey »
The discovery in 1993 of mechanical principles that allowed a predictive reversal of natural tooth intrusion associated with dental implants started a two decades journey into research on biomechanical principles of implants and teeth co-existing in the oral cavity. A disruptive technology, quantitative percussion diagnostics, was originally developed to prove the tooth intrusion hypothesis published in 1993. The follow on paper in 1997 introduced a medical device that could mechanically test teeth and implants to establish discrete levels of structural stability. Further, it could monitor the sites for damage in a non-destructive, pain free, rapid and reproducible manner.
Quantitative percussion testing allows a clinician to evaluate the structural stability of natural teeth or dental implants by measuring the micro-movement created from a light impact on the buccal surface. The energy that is returned to the hand piece is analyzed in a manner that provides quantitative metrics on the structured stability of the site during mastication and parafunction. This information can give the clinician indications of how sound the tested structure is. Physiological micromovement is produced by a normal periodontal ligament or bone. Pathological micromovement is produced by defects that create movement directly adjacent to the structure or internal to the tooth or implant. Armed with this knowledge, the clinician will be prepared to look for potential problems where abnormal results are observed. Additionally, patients become educated on the bioengineering challenges that some teeth or implants present due to internal defects and have a more realistic perspective on longevity of results and need for preventive compliance.
