Stabilitätsmessung an kieferorthopädischen Implantaten: Ist die Resonanzfrequenzanalyse als diagnostisches Tool geeignet?

Zusammenfassung

Ziel der prospektiven randomisierten Studie war den klinischen Stellenwert der Resonanzfrequenzanalyse als diagnostisches Instrument zur Vorhersage von Implantatverlusten bei Gaumenimplantaten zu untersuchen.

Dazu wurden 29 Patienten aus einer RCT Studie [1, 2] innerhalb eines Studienzentrums betrachtet, bei denen ein Gaumenimplantat zur skelettalen Verankerung inseriert wurde. Die Parameter Implantdesign, Insertionsort und Knochenqualität blieben bei allen Patienten nahezu konstant. Im Rahmen des Studien-protokolls war die Resonanzfrequenzanalyse als diagnostisches Instrument nicht geeignet, Gaumenimplantatverluste frühzeitig und sicher zu identifizieren. Trotz einer homogenen Kohorte von Patienten und nahezu konstanten Bedingungen in Bezug auf Implantat-Typ, -dimension und Insertionsort erlaubten die postoperativen Messungen der Implantatstabilität zu Beginn der Untersuchung, also unmittelbar nach der chirurgischen Insertion und eine Woche später, keine Aussage zur Wahrscheinlichkeit späterer Implantatverluste.

Abstract

The aim of this prospective randomized study was to investigate the clinical significance of resonance frequency analysis as a diagnostic tool for predicting implant loss in palatal implants.

To this end, 29 patients from an RCT study [1, 2] within one study center who had received a palatal implant for skeletal anchorage. The parameters of implant design, insertion site, and bone quality remained stable in all patients. Within the scope of the study protocol, resonance frequency analysis was not suitable as a diagnostic tool for the early and reliable identification of palatal implant loss. Despite a homogeneous cohort of patients and nearly constant conditions in terms of implant type, dimension, and insertion site, the postoperative measurements of implant stability at the beginning of the study, i. e., immediately after surgical insertion and one week later, did not allow any conclusions to be drawn about the probability of later implant loss.
