A bone surface anchoring type dental implant design method with a topological optimization structure and an implant

Abstract

A bone surface anchoring type dental implant design method with a topological optimization structure comprises the following steps of (1) obtaining an oral maxillofacial CT image of a patient, and using the medical image processing software for reconstructing a three-dimensional model of a mandible of the patient, wherein the reconstructed model further comprises a mandibular nerve canal anatomical structure; 2) measuring and evaluating a tooth missing condition and a bone mass condition of an implant implanting part in medical image processing software, determining a position of a repairing base station, and formulating a comprehensive repairing scheme; determining the position and form of the implant, implanting a traditional cylindrical or conical dental implant at a position with sufficient or insufficient bone mass; and designing the bone surface anchoring type implant at the position where the serious bone mass is insufficient. The invention provides the bone surface anchoring type dental implant design method with the topological optimization structure and an implant. The implant is different from a traditional subperiosteal implant and a root-shaped implant, and the bone increment operation is not needed.

Description

technical field [0001] The invention relates to a design method of a bone-surface anchored dental implant with topology optimization structure and the implant. Background technique [0002] At present, with the increasing development of society, people's pursuit of oral aesthetics is getting higher and higher. Tooth loss affects oral relationships and is also aesthetically pleasing. Dental implants have increasingly become the main choice for missing teeth due to their advantages of aesthetics, comfort, and high chewing efficiency. However, traditional root-shaped implants have higher requirements on bone mass, including bone height and bone width, which need to meet the requirements of implant surgery. If the alveolar bone volume is insufficient, there may be risks of failure in implant restoration, including insufficient bone width causing the implant side to protrude from the alveolar bone, insufficient bone height leading to implant exposure, and insufficient initial s...

Problems solved by technology

[0005] In order to solve the problem that multi-stage surgery must be performed for dental implant restoration in patients with severe bone deficiency, that is, the problem of first replenishing bone mass and then implanting the implant, the present invention provides a bone-surface-anchored dental implant with a topology optimized structure The design method and implants are different from traditional subperiosteal implants and root implants and do not require bone augmentation operations
