[0002] Dental implant surgery is an important treatment method in modern stomatology, used to replace missing teeth. However, the success of implant surgery depends on a good match between the implant and the alveolar bone to ensure the stability and biocompatibility of the implant. Traditional implant design methods mainly rely on the doctor's experience and fixed design parameters, which have certain limitations in dealing with individual differences of different patients and complex clinical situations.

[0003] In the existing technology, the design of alveolar bone augmentation morphology is usually evaluated using two-dimensional imaging data, lacking a comprehensive analysis of the three-dimensional structure, which makes it difficult for the design results to accurately reflect the actual bone structure characteristics. In addition, the traditional method of evaluating the quality and structure of the alveolar bone is mostly based on the doctor's subjective judgment, lacking a systematic and accurate analysis method. This situation not only increases the uncertainty of the operation, but may also affect the long-term stability of the implant and the patient's rehabilitation effect.

[0004] Traditional design methods often fail to fully consider individual factors such as the patient's bone condition, tooth arrangement, age-related bone remodeling characteristics, and bone tissue response under the influence of drugs when optimizing the shape, size, and position of implants. As a result, the designed implant may not achieve the expected effect during the actual implantation process, and may even lead to surgical failure or late complications.

[0196] The multi-agent system of this embodiment proposes a new solution for the intelligent design of alveolar bone augmentation morphology. It simulates and analyzes various complex clinical scenarios by configuring different agents, thereby achieving individualization and precision in implant design. First, three-dimensional image data of the patient's alveolar bone and oral structure are acquired through computed tomography, and key biomechanical properties in the three-dimensional image data are extracted. These steps ensure that the acquired data is highly accurate and reliable, providing a solid foundation for subsequent intelligent analysis.

[0197] In the multi-agent system, each agent is configured according to different clinical scenarios or tasks, such as osteoporosis, tooth arrangement, age-related bone remodeling characteristics, and bone tissue response under the influence of drugs. Each agent automatically analyzes the quality and structural characteristics of the alveolar bone through a preset algorithm, and evaluates the risks and potential problems associated with implant placement, including evaluating the stress distribution of the alveolar bone and possible fracture risks through a bionic model. Agents exchange information and collaborate with each other through a preset communication protocol, and optimize the shape, size, and position of the implant by simulating different design schemes and implantation strategies. At the same time, the alveolar bone augmentation morphology is designed to confirm bone support and improve the integration of bone structure and implants.

[0198] Compared with the prior art, the present invention overcomes the limitations of traditional design methods and achieves comprehensive simulation and precise analysis of complex clinical situations through a multi-agent system. Due to the lack of comprehensive analysis of three-dimensional structures and systematic biomechanical evaluation in the prior art, it is difficult to achieve individualized and precise optimization of implant design. The method based on a multi-agent system can comprehensively consider various individual differences of patients and generate the optimal design plan, thereby improving the success rate of implant surgery and the rehabilitation effect of patients.

[0199] In summary, the intelligent design method of alveolar bone augmentation morphology based on a multi-agent system, based on the existing technology, realizes the individualization and precision optimization of alveolar bone and implant design by introducing a multi-agent system and advanced biomechanical evaluation methods, overcomes the shortcomings of traditional methods, and provides a more scientific and reliable solution.

[0200] The present invention uses computer tomography to obtain three-dimensional image data of the patient's alveolar bone and oral structure, and extracts key biomechanical properties, making the design process highly accurate and personalized. During the analysis process, the intelligent agent takes into account the patient's bone condition, tooth arrangement, age-related bone remodeling characteristics, and bone tissue response under the influence of drugs, and can perform targeted design optimization according to specific circumstances.

[0201] The multi-agent system of the present invention can simulate a variety of clinical scenarios. Through preset algorithms and communication protocols, agents can exchange information and collaborate with each other, thereby comprehensively simulating different design schemes and implantation strategies. This process not only optimizes the shape, size and position of the implant, but also optimizes the design of the alveolar bone augmentation morphology to ensure bone support and the integration of the implant and bone structure, thereby greatly improving the planning and rehearsal effects before surgery and reducing the uncertainty and potential risks in the actual surgery.

[0202] In the present invention, each intelligent agent automatically analyzes the quality and structural characteristics of the alveolar bone according to a preset algorithm, and evaluates the risks and potential problems associated with implant placement, including evaluating the stress distribution and fracture risk of the alveolar bone through a bionic model. The generated risk assessment report identifies high-risk areas in detail and provides improvement suggestions, which helps doctors make adequate preparations before surgery and improves the success rate and safety of the surgery.

[0203] The collaborative analysis and information sharing between the intelligent agents of the present invention enable the design scheme to be optimized through multiple iterations. Through finite element analysis and multi-scale modeling technology, the optimized implant and alveolar bone augmentation morphology design can meet individual needs to the greatest extent, ensure biomechanical performance and biocompatibility, and provide optimal design parameters.

[0204] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
