Effect of different ridge heights and duplication methods on the accuracy of mandibular complete denture duplication

Statement of Problem. The precision of complete denture duplication is fundamental to ensuring mandibular dentures’ clinical functionality and comfort. However, variations in ridge height and the choice of duplication technique can significantly affect the accuracy of the final prosthesis. With the continuous development of intraoral scanning technologies, there is a need to evaluate and understand their effectiveness in producing accurate denture duplicates compared to conventional methods.
