Artificial intelligence in intact tooth model creating and strength testing

Aim or purpose: Artificial intelligence (AI) is becoming an increasingly common, widely used tool for intact tooth 3 modeling from CBCT scans. Also, AI could be used for biomechanics testing, with high value of accurate. Materials and methods: CBCT of the patient was made. After exporting the DICOM format of CBCT in 3D Slicer the upper left central incisor was isolated as volumetric finite element model from the maxilla and then its mesh was corrected and refined in 3D Slicer and Meshmixer. The next step was to convert the exported ASCII code from Mesh mixer into appropriate ASCII code for SOFiSTiK with the help of artificial intelligence. The 3D intact tooth model was made with all biological tissue properties. With that, the volumetric model was ready and subjected to strength testing with SOFiSTiK. Results: The fracture resistance testing was conducted in SOFiSTiK. The results have shown that the intact tooth has a high value of strength, around 1350 N. This value is near to value of in vitro testing with Universal Testing Machine. Conclusions: Today, in vitro fracture resistance studies have been totally replaced with artificial intelligence algorithms studies. This way of testing the fracture strength could save moneyandtimewithvalueofaccurate asinvitro testing. Key Words: finite element model, finite element analysis, artificial intelligence, intact tooth, strength testing.
