Occlusion-oriented implant surgery device for missing dentition and preparation method thereof

Abstract

The invention discloses an occlusal relationship-oriented implantation surgical device for missing dentition and a preparation method thereof. An implantation guide plate includes a guide plate base body, and the guide plate base body is prepared by 3D printing by obtaining the occlusal relationship of a patient. The jawbone of the patient is matched in shape and size; the guide plate base body is provided with a plurality of first retaining pin placement bodies, a plurality of osteotomy positioning bodies and implant site bodies; the first retaining pin placement body, the osteotomy positioning body A first guide hole is arranged on both the implant site body and the implant site; and a temporary restoration body, the temporary restoration body is prepared by 3D printing by obtaining the occlusal relationship of the patient, and the temporary restoration body has a plurality of second retention pins. The mounting body is provided with a second guide hole on the second retaining pin mounting body. The surgical device provides an occlusal relationship-oriented implantation guide plate for implantation surgery for missing dentition, the guide plate has a structure integrating retention, osteotomy and implantation sites, and can ensure the accurate placement of the temporary restoration.

Description

technical field [0001] The invention belongs to the department of oral implantology, relates to the field of clinical research of oral implantology and supporting equipment, and in particular proposes an occlusal relationship-oriented implant surgery device for missing dentition and a preparation method thereof. Background technique [0002] Data show that the proportion of dentition in the elderly aged 65-74 is 4.5%. Dentition loss affects the patient's jaw structure, aesthetics, pronunciation, chewing, and psychological state. The World Health Organization defines this group of people as disabled. Traditional complete denture restoration will lead to continuous bone resorption in edentulous patients, and the chewing efficiency will be severely reduced. The chewing efficiency of natural teeth is 200psi, and that of complete dentures is 50psi. After 15 years of wearing complete dentures, the chewing efficiency drops to 5.6psi. [0003] The use of implant-supported restora...

AI Technical Summary

Problems solved by technology

[0007] Problem 1: The implant surgical guides for patients with missing dentition are mostly mucosa-supported implant guides, but the accuracy of this guide is significantly lower than that of tooth-supported guides

[0008] Problem 2: The anterior tooth area of ​​patients with edentulousness often needs bone modification. The osteotomy guide plate designed by digital technology is conducive to accurately determining the osteotomy position. However, the guide plate needs to be replaced during the operation and the processing cost is increased.

[0009] Question 3: Digital technology can prefabricate temporary restorations before surgery. Wearing the prefabricated restorations immediately after the surgical operation greatly shortens the time at the chair. Only when implants are implanted in assisted-designed implant sites and there is no difference in implant depth can the accurate placement of temporary immediate dentures be ensured, which has great limitations in clinical application
