Method for assisting in alignment of dental prosthesis and dental implants for full arch dental implant placement

A method for assisting in alignment of a dental prosthesis and dental implants for full arch dental implant placement, comprising:

• obtaining, by a digital intraoral scanner, a first digital intraoral scan image of an oral cavity of a patient;
• creating, by a processing device, with reference to the first digital intraoral scan image, a three-dimensional (3D) virtual dental prosthesis model that serves as a basis for producing a dental prosthesis for the patient;
• obtaining an adaptive element including a prosthetic prototype that is produced based on the 3D virtual dental prosthesis model, and a plurality of matching indicators that are attached on the prosthetic prototype according to preset conditions;
• obtaining, by the digital intraoral scanner, a second digital intraoral scan image of the oral cavity of the patient when the adaptive element is attached to a gum of the patient, the second digital intraoral scan image showing the adaptive element that includes the matching indicators;
• obtaining, by a tomographic device, a tomographic scan image of the oral cavity of the patient when the adaptive element is attached to the gum of the patient, the tomographic scan image showing an alveolar bone of the patient and the matching indicators,
• superimposing, by the processing device, the second digital intraoral scan image and the tomographic scan image on each other by aligning the matching indicators, so as to generate a superimposed image;
• and
• outputting, by the processing device, based on the second digital intraoral scan image, the tomographic scan image and the superimposed image, a plan for implanting the dental implants into the alveolar bone.
