Description

Technical Field

[0001] This invention belongs to the field of dental implant restoration technology, specifically relating to a method and system for implant restoration of edentulous jaws. Background Technology

[0002] With the increasing aging population, the demand for edentulous jaw implant restoration is rising year by year. Computer-aided implant surgery (CAIS) technology (static / dynamic CAIS) and digital tools (scanning, design, CAD / CAM) are gradually being applied. However, existing technologies have the following key defects due to information silos and lack of unified data in each stage: 1. Information silos lead to data fragmentation. Edentulous jaw implant restoration involves multiple stages such as data acquisition, implant design, surgical guidance, and restoration manufacturing. Each stage relies on independent digital tools (scanning equipment, design software, navigation systems). Incompatible data formats and inconsistent spatial coordinates between tools create "information silos"—preoperative planning data cannot be directly transferred to the intraoperative stage, and postoperative feedback data is difficult to use to improve preoperative optimization, resulting in a data gap throughout the entire process; 2. Data registration lacks rigid benchmarks. Edentulous jaw patients lack fixed anatomical landmarks of natural teeth in their mouths. Traditional digital... The process relies on soft tissue surface data or anatomical landmark registration, which is easily affected by soft tissue deformation and bone atrophy. Furthermore, there are no clear standards for marker implantation sites and registration accuracy, making it impossible to establish a rigid benchmark, and precision depends on experience. 3. The process lacks clear data thresholds: the delivery standards and error tolerance ranges for each stage (data acquisition-design-surgery-restoration) are not quantified. For example, there is no unified judgment on implantation deviation and jaw position transfer angle deviation, resulting in poor consistency in treatment effects among different institutions and doctors, and low reproducibility. 4. Closed-loop optimization lacks data feedback rules: the existing process only focuses on data recording at a single stage, failing to establish a closed loop of "deviation data-real-time feedback-parameter correction." It cannot use postoperative data to inform preoperative planning, leading to repeated errors in similar cases. Moreover, existing technologies lack unified navigation data. Therefore, our company has designed and proposed a method and system for edentulous jaw implant restoration based on these needs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as information silos leading to data fragmentation, lack of rigid benchmarks for data registration, lack of clear data thresholds for process connections, lack of data feedback for closed-loop optimization, and lack of unified navigation data. This invention proposes a method and system for edentulous jaw implant restoration. This method solves the problems of "information silos," lack of unified data rules, and uncontrollable results in traditional processes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a method for implant restoration of edentulous jaws, including the following steps: Step 1: Reception and routine information collection for edentulous patients; Step 2: Strategically implant micro-spiral nails; Step 3: Preoperative data collection and treatment plan planning: Intraoral trial fitting and adjustment of the radiological diagnostic guide, intraoral scanning to obtain the prosthesis data as A.stl, recording the jaw position relationship under occlusion and taking CBCT, recording the jaw position relationship as data A.dcm, and completing the implant treatment plan planning; Step 4: Using the micro-spiral nail as a reference for registration and navigation, synchronize data A to guide implantation; Step 5: Immediate postoperative data acquisition, record scan data B.stl, and complete immediate postoperative impression taking; Step 6: Temporary restoration fabrication and AI data accumulation: Align data A and data B, fabricate a temporary prosthesis, record the restoration and jaw position information data C, and carry out AI data accumulation and training; Step 7: Fabricate the final prosthesis and record the jaw position and prosthesis information data D; Step 8: Data integration and analysis: Compare data A with data C, data A with data D, and data C with data D to analyze implant / jaw position deviation; Step 9, Deviation Judgment and Optimization: When the deviation is less than or equal to the threshold, the implant design, data A parameters, and registration parameter logic are corrected, and the data is archived and iterated.

[0005] Furthermore, in step 2, the micro-spiral nail is made of titanium alloy and has a 0.38mm diameter concave structure at the top. The specifications include Φ2.0×8mm and Φ2.0×10mm. The implantation sites are the maxillary tuberosities and anterior nasal spine regions on both sides of the maxilla, and the retromolar pad region and mental spine region on both sides of the mandible.

[0006] Furthermore, in step 4, the registration and navigation accuracy is ≤0.1mm, the real-time feedback delay is ≤0.1s, the deviation from cheek to neck is 1.13±0.54mm, the root tip is 0.87±0.47mm, and the angle deviation is ≤1.47±1.02°.

[0007] Furthermore, the data formats of data A, data B, data C, and data D are unified as STL / DCM, achieving full device compatibility and flow.

[0008] To address the aforementioned technical issues, this invention also proposes an edentulous jaw implant restoration system for the aforementioned edentulous jaw implant restoration method, comprising a data acquisition module, a digital surgery module, a restoration design module, and an AI analysis and optimization module; The data acquisition module is used for full-process data recording; The digital surgical module is used for navigation registration and implant guidance; The repair design module is used for the digital fabrication of repairs; The AI ​​analysis and optimization module is used for deviation analysis, parameter correction, and data iteration.

[0009] The present invention proposes a method and system for implant restoration of edentulous jaws, the advantages of which are as follows: (1) This invention breaks down information silos by using rigid benchmarks and uses titanium alloy micro-spiral nails as data anchors throughout the process to achieve seamless data flow between CBCT, oral scanning, navigation and processing equipment, thus completely eliminating data gaps.

[0010] (2) This invention realizes a closed-loop data chain, covering the entire process of preoperative planning, intraoperative navigation, immediate postoperative care, temporary repair and final repair. It adds multi-dimensional deviation comparison, making the judgment more comprehensive and accurate.

[0011] (3) This invention enables AI-driven continuous iteration, establishes a case data accumulation and training mechanism, and realizes standardized and replicable treatment plans to continuously improve clinical accuracy.

[0012] (4) The present invention improves both efficiency and experience, significantly shortens chairside jaw adjustment time, and avoids the discomfort of traditional impression taking by digitalization of the whole process, and significantly improves patients' chewing function and social confidence.

[0013] (5) The data of this invention is traceable and serializable: the data of the whole process is archived and archived, supporting horizontal comparison of multiple cases and long-term optimization to form a standardized clinical pathway. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] The structural features of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] See Figures 1-7 A method for edentulous jaw implant restoration, specifically including the following steps: S1. Reception and Routine Information Collection for Edentulous Patients. This involves routine reception of edentulous patients, collecting basic information such as medical history, intraoral examination, and facial records, and establishing a dedicated patient file.

[0018] S2. Strategic placement of micro-spiral screws. Implantation sites are the bilateral maxillary tuberosities and anterior nasal spine region in the maxilla, and the bilateral retromolar pads and mental spine region in the mandible, serving as rigid reference markers for both radio-optical modalities. The micro-spiral screws are made of titanium alloy and feature a specially designed 0.38mm diameter recessed structure at their tip. Available sizes include Φ2.0×8mm and Φ2.0×10mm.

[0019] S3. Preoperative data collection and treatment plan planning: intraoral trial fitting and adjustment of the radiodiagnostic guide; intraoral scanning to obtain prosthesis data as A.stl; recording jaw position relationship under occlusion and taking CBCT to record jaw position relationship data as A.dcm; using micro-spiral screws as rigid reference points to reconstruct the coordinate system; and completing the implant treatment plan based on evidence-based criteria.

[0020] S4. Digitally Guided Implant Surgery: Utilizing a digital guide plate or dynamic navigation-guided surgery, navigation registration is completed using micro-spiral nails as a reference. Synchronous data A guides precise implant placement in real time. Dynamic navigation registration accuracy ≤0.1mm, real-time feedback delay ≤0.1s; buccal-lingual deviation to neck 1.13±0.54mm, apical deviation 0.87±0.47mm, angular deviation ≤1.47±1.02°. S5. Immediate Postoperative Data Acquisition: Scanning is performed using an intraoral scanning rod, conventional post-imprint chamber scanning, or SPG extraoral radiography. Scan data is recorded as B.stl, obtaining a digital working model for immediate postoperative impression taking.

[0021] S6. Temporary restoration fabrication and AI data accumulation: Align data A and B, fabricate temporary dentures, record the restoration and jaw position information as data C using dual scanning, simultaneously input case data, and conduct AI model training and application path construction.

[0022] S7. Fabricate the final restoration, record the jaw position and restoration information as data D, and simultaneously carry out AI data accumulation and model training to complete the digital design and processing of the final restoration.

[0023] S8. Comprehensive data deviation analysis accurately analyzes implant position and jaw alignment deviations. Data integration analysis: Comparing data A (preoperative planning) vs. data C (immediate postoperative), data A (preoperative planning) vs. data D (final restoration), and data C (immediate postoperative) vs. data D (final restoration), comprehensively analyzes implant / jaw alignment deviations. By cross-comparing three sets of core data: A vs. C, A vs. D, and C vs. D, the deviations in implant position and jaw alignment are accurately analyzed. The entire process uses a unified STL / DCM data format, achieving full-chain compatibility with intraoral scanning, CBCT, navigation, and processing equipment.

[0024] S9. Solution optimization and data iteration: If the deviation is less than or equal to the set threshold, correct the implant design parameters, A data parameters and registration logic; all case data are archived for subsequent case linking, AI training and full-process optimization.

[0025] This edentulous jaw implant restoration method achieves a fully integrated approach to edentulous jaw implant restoration with closed-loop management as the goal and data rules as the core. It is suitable for precise implant restoration of edentulous patients with different degrees of bone atrophy, realizing full-process digitalization, datafication, and closed-loop management. Clinical accuracy, treatment efficiency, and patient experience are significantly better than traditional methods. The core solution is to address the problems of "information silos" formed by each link in the traditional process, the lack of unified data rules, and the uncontrollable results. It achieves full-chain data traceability, optimization, and replicability from preoperative planning to postoperative restoration. It establishes a rigid registration benchmark rule of "titanium alloy micro-spiral nail markers" (clearly defining the implantation sites: bilateral maxillary tuberosities + anterior nasal spine region, bilateral mandibular retromolar pads + mental spine region) as the "anchor point" for data connection throughout the process, realizing seamless data flow from CBCT, intraoral scanning, navigation, and processing equipment, and completely breaking down information silos between links. "Unified Rules + Navigation Adaptation": For the first time, scattered industry consensus was integrated with existing clinical data to formulate unified data format rules (STL), coordinate calibration rules (micro-screw reference), and error threshold rules. These rules are not tied to specific navigation brands; as long as the navigation device meets the requirements of "registration accuracy ≤ 0.1mm and real-time feedback latency ≤ 0.1s," the time required for chairside jaw adjustment was reduced from the traditional 44.2±6.9 ​​minutes to 14.8±3.1 minutes, a 66.5% reduction (P<0.001). This high efficiency stems from seamless data flow. Patient experience was improved: the OHIP-14 score improved by -29.7±4.2 points, significantly better than the traditional method (-16.5±5.8 points, P<0.001), and avoided discomfort such as nausea and taste irritation caused by traditional impression taking. Significant improvements were observed in chewing function (Δ=-7.2±1.1) and social confidence (Δ=-6.5±0.9).

[0026] This embodiment also provides an edentulous jaw implant restoration system for performing edentulous jaw implant restoration methods, including: Data acquisition module: used for collecting patient reception information, recording and storing full-dimensional data (Data A.stl / A.dcm, Data B.stl, Data C, Data D); Digital surgical module: used for digital guide design and dynamic navigation registration, using micro-spiral nails as a rigid reference to guide implant placement; Restorative design module: used for A / B data alignment, digital design and fabrication of temporary dentures and final restorations; AI Analysis and Optimization Module: Used for cross-comparison of three sets of data, implant / jaw position deviation analysis, AI data training, parameter correction, and case data iteration.

[0027] This edentulous jaw implant restoration system establishes a closed loop of "data acquisition - surgical execution - deviation analysis - parameter correction". Postoperative deviation data (such as jaw position and implant deviation) is automatically fed back to the preoperative planning module. Combined with clinical data, the system updates and optimizes the rules to improve the accuracy of subsequent cases. The entire process is traceable: the platform records micro-screw implantation data, scanning data, design parameters, surgical deviations, and restoration processing data. Every step is documented and can be repeatedly refined.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
