Application of spiral computed tomography in clinical dental implantation / 中国基层医药

ABSTRACT

Objective To evaluate the value of spiral CT and panoramic radiographs in preoperative assessment the jaw condition of patients for dental implantation.Methods 80 patients required dental implant restoration,these patients were Manned by CT and panoramic radiographs in preoperative,then selected suitable patients for dental implant restoration,reconstructed the jaw based on spiral CT data and guided the dental implant design and implanration.Results The spiral CT examination could be more accurate selection criteria for the patients needed dental implant restoration and more accurately showed the situation of edentulous ridge bone.Conclusion The reconstructed of three-dimensional imaging of spiral CT could precisely show the bone situation in the jaw needed dental implant and the important anatomic structures,could effectively assist denture design and the direction and depth of dental implants.was more superiority than panoramic radiographs.
