Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant procedures rely heavily on dentist experience for accurate positioning, leading to potential instability and increased operation time, as they lack precise methods for determining the ideal location and depth of implant placement.
Innovation Solution
A dental implant surgical guide manufactured using three-dimensional stereoscopic images, comprising a retainer, guide portion, and indicator, which guides the placement of the implant platform and hole with high accuracy, reducing the need for manual estimation and improving the success rate of dental implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dental implant positioning relies on dentist experience and two-dimensional X-ray images, then the procedure can be performed with simple equipment, but the positioning accuracy and implant stability deteriorate
Solution Approach 1:
The surgical guide is manufactured before the implant procedure using three-dimensional stereoscopic images of the patient's oral cavity. This preliminary action allows precise determination of implant location, depth, and angle in advance, eliminating the need for complex intraoperative adjustments and improving positioning accuracy without adding operational complexity.
Solution Approach 2:
The surgical guide creates a physical three-dimensional model or digital replica of the patient's oral cavity structure. This copy allows for precise planning and simulation of implant placement before the actual surgery, enabling high positioning accuracy while keeping the surgical procedure itself relatively simple.
2Productivity
If implant placement relies on manual estimation by the dentist, then the operation procedure remains simple, but the operation time increases and success rate decreases
Solution Approach 1:
All critical positioning decisions are made in advance through three-dimensional imaging and surgical guide fabrication. The implant location, depth, and angle are predetermined, allowing the surgeon to simply follow the guide during the procedure. This dramatically reduces operation time while ensuring high success rates through precise pre-planning.
Solution Approach 2:
The surgical guide acts as an intermediary device that translates the pre-planned implant position into physical guidance during surgery. It mediates between the digital three-dimensional plan and the actual surgical execution, ensuring that the predetermined precise position is accurately achieved without requiring complex real-time decision-making during the procedure.
3Manufacturing precision
If implant depth and angle are determined during surgery based on bone location, then the procedure is easier to perform, but angular symmetry is poor and implant stability decreases
Solution Approach 1:
The surgical guide is fabricated with pre-determined depth stops and angular guides based on the three-dimensional oral cavity model. These physical constraints ensure that the implant is placed at the precise predetermined depth and angle, eliminating the need for complex intraoperative measurements while maintaining high precision.
Solution Approach 2:
The surgical guide serves as a physical intermediary that enforces the pre-planned depth and angle constraints during implant placement. It translates the digital three-dimensional plan into tangible surgical constraints, making precise implantation straightforward by guiding the drill and implant along predetermined paths without requiring complex real-time adjustments.

AI summary
A dental implant surgical guide and manufacturing method thereof are provided. The dental implant surgical guide comprises a retainer, a guide portion, and an indicator. Said guide portion is located on either the tongue side or the palatal side of a patient, and comprises a guiding groove corresponding to an implant hole and an opening being connected to the guiding groove; said indicator comprises an extension portion and a terminal, wherein the extension portion is extended from the retainer to an implant platform of a missing tooth portion, while the terminal indicates a location of the implant platform. Therefore, locations of the implant platform and the implant hole of the missing tooth portion will be positioned by the dental implant surgical guide when placing the dental implant surgical guide on the missing tooth portion.
