Abstract:: Objective To design and implement a cone beam computed tomography (CBCT)-based system for construction of gum structure and customization of dental implant, determine the parameters of dental implant model by observing constructed gum structure, and evaluate its therapeutic effect. Methods A dental implant digitalization software was developed to integrate the dental implant model into the environment of CBCT gum reconstruction. According to the clinical customization requirements and the requirements of surgical specifications, a customized dental implant mode was designed. Results The proposed software system not only realized the three-dimensional reconstruction and display of the gum structure based on DICOM format data, but also achieved the customization of dental implant data in accordance with STL format, three-dimensional display and two-dimensional tangential projection. The abutment height, neck height and angle, length and diameter of the body could be manually adjusted, and the display of three-dimensional structure of the adjusted dental implant was updated. Finally, dental implant data in accordance with STL format were exported. Conclusion The proposed system can be used to complete the customized manufacturing and interface packaging of dental implant in the software, which not only meets the requrements of clinical customization and surgical specifications, but also significantly improves the cycle and cost of diagnosis and planting planning.
