LEIPZIG, Germany: Minimal bone loss around dental implants is one of the primary design principles in dental implantology. On 29 September, the Dental Tribune Study Club is presenting a webinar that discusses the bone remodelling process around dental implants in terms of biomechanical principles. The online course is free of charge and offers participants the opportunity to earn a continuing education credit.

According to the theory of US orthopaedist and surgeon Dr Harold M. Frost, non-physiological bone overloading may be the reason for the bone remodelling process around dental implants. Another possible reason is bacterial contamination via the functionally related micro-gap that occurs in the implant-abutment connection during chewing.

The webinar will discuss the basic biomechanical principles of the bone remodelling process around dental implants. Using the finite element method, the stresses around osseointegrated dental implants will be visualised. Moreover, course speaker Prof. Matthias Flach will explain the biomechanically induced bone remodelling process based on bone stress distribution.

The design of the implant–abutment connection has a major influence on bone stress distribution. In order to illustrate the differences between various implant–abutment connections, seven types of implants will be examined, including those with flat connections, small conical connections and 45-degree conical connections. Flach will explain the biomechanical effect of each group in terms of bone stress.

The micro-gap that appears during chewing is considered responsible for the bacterial contamination around dental implants. The link between the different implant–abutment connection types, preload of the implant–abutment connection screw and the micro-gap will be discussed. Additionally, Flach will offer practical advice on the use of the different connection types in daily practice.

Flach studied theoretical mechanical engineering at the University of Siegen in Germany from 1984 to 1990 and began working as an engineer in structural mechanics and dynamics in 1990. Since 2003, he has been Professor of Mechanics and Mechatronics at the Koblenz University of Applied Sciences in Germany.

The webinar, titled “Biomechanical basis of the bone remodeling process around dental implants”, is free of charge and will be broadcast online on Tuesday, 29 September at 10 a.m. EST. Participants will be able to ask questions via a chat window and have the opportunity to earn a continuing education credit by completing a multiple-choice questionnaire on the topic discussed.

Registration for the webinar is now open on www.dtstudyclub.com.
