Periodontal ligament (PDL) contributes to the stability of the tooth-PDL-bone structure (T-PDL-B) under impact loading. In the case of inserting a dental implant into the bone, the dental implant-bone (DI-B) construct will be more prone to the mechanical damage caused by impact loading, compared to the T-PDL-B construct. This study aims to identify main differences in the behaviour of T-PDL-B and DI-B constructs under impact loading using ex-vivo impact tests.
