Analog and digital modeling of sound and impaired periodontal supporting tissues during mechanical testing

Periodontitis is one of the most common conditions affecting oralhealth among adults, posing a great challenge for both patients and alsofor dentists aiming to treat this disease. In severe stages suchdeterioration of the supporting tissues, namely the periodontal ligamentsand the bone, can occur, which will affect the biomechanical behavior andtherefore the longevity and survival of the affected teeth. In order to beable to plan both periodontal and subsequent restorative treatmentproperly, valid modelling of the current clinical situation is advised. Theaim of the present article is to comprehensively discuss possible analogand digital modeling methods of periodontally affected teeth and theperiodontal structures surrounding them. Modelling possibilities can servelater as the basis of mechanical load, digital finite element studies, andalso aid clinical treatment planning.
