Lecture Topic:
All that glitters ain't Gold – Comparison of Ceramic Implants under Quality Aspects

Course Description:

Neither the announcement of legal action against the publication of analysis results nor threats against the investigating scientists change anything about the findings: Recent quality assessment studies of sterile-packaged implants, conducted in collaboration with Charité – University Medicine Berlin, revealed an alarming number of dental implants with significant factory-related contaminants. Unfortunately, not only implants made of titanium but also numerous ceramic implants showed impurities, which can lead to unwanted foreign body reactions and even peri-implantitis. The lecture illustrates the nature and extent of the findings, describes clinical consequences for patients, legal consequences for dentists, and shows how such risks can be avoided in the long term.

2 multiple-choice questions (if needed for credits):

(1) Contaminants on the sterile implant surface…

FALSE: …can be detected with the naked eye and should be removed by the practitioner by rinsing with saline solution.

CORRECT: …can have an influence on the healing process.

(2) Foreign body particles with a size of 0.2 µm to 7.2 µm are considered particularly…

FALSE: …biocompatible.

CORRECT: …proinflammatory.
