Computer 3D and 4D Modelling in Bone Remodelling and Regeneration
Abstract
Aim or Purpose: Bone is responsive to mechanical stresses and obtains internal form optimal for the distribution of internal forces. According to Wolff's law, bone must be deposited in sites of stress and resorbed where mechanical loading is insufficient to maintain bone mass. The aim of the study is to investigate stress and strain around the soft and hard tissues around unerupted teeth. Materials and Methods: This study uses a computer modeling approach (Finite Element Analysis), applying ScanIP (V2022) and ANSYS Workbench (V18) software. Finite Element Analysis (FEA) permits the biomechanical computation of complex problems to predict the response of complex structures subjected to external loading. In this study, 12 different models have been generated, and by using Prism-9 all the graphs and data were added. Results: The response of bone to function entails bone undergoing constant resorption coupled with new bone formation. This perpetual process of bone turnover seems particularly well suited for rapid structural adaptation to physical needs in this study. Tension on bony surfaces in our models results in bone formation, and compression on bone surfaces stimulates bone resorption. Similar data demonstrate the consistency of tooth eruption theory in our models. Conclusions: The mechanical forces at the critical bone-soft tissue interface drive bone remodeling to deposit bone beneath the tooth whilst resorbing it above.
