Non-incisional Dental Implant Guide Pin for Alveolar Bone Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant surgery methods face challenges in accurately forming implant holes in the alveolar bone without incising the gingiva, leading to potential misalignment and increased surgical complexity, which can lower success rates and prolong recovery times.
Innovation Solution
A non-incisional dental implant surgical method using a guide pin with an insertion portion and guide portion, allowing practitioners to determine the shape and direction of the alveolar bone without cutting the gingiva, by inserting the guide pin between the alveolar bone and periosteal membrane, and using the exposed guide portion to drill the implant hole accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an incision is made in the gingiva to expose the alveolar bone for accurate implant hole formation, then the manufacturing precision of implant placement is improved, but the patient's recovery time and convenience deteriorate
Solution Approach 1:
The patent introduces a guide pin as an intermediary tool that extends through the gingiva to reach the alveolar bone. The guide pin serves as a mediator between the practitioner and the bone structure, allowing visualization and measurement of the alveolar bone shape without requiring incision. The guide pin includes a guide portion visible through the gingiva and a tip that contacts the alveolar bone, enabling indirect measurement and planning of implant hole formation while preserving the gingiva.
2Device complexity
If the alveolar bone shape is determined without real-time X-ray or CT imaging during surgery, then the device complexity and surgical time are reduced, but the measurement precision of alveolar bone geometry deteriorates
Solution Approach 1:
The guide pin enables the alveolar bone to essentially measure itself through direct physical contact. By inserting the guide pin tip into the alveolar bone and rotating it to contact different points on the bone surface, the system allows the bone structure itself to define its geometry through the mechanical interaction with the guide pin. This self-measurement approach eliminates the need for complex imaging equipment while achieving accurate bone shape determination through direct tactile feedback and visual observation of the guide pin position.
3Ease of operation
If a guide pin is inserted between the alveolar bone and periosteal membrane to enable non-incisional surgery, then the ease of operation and patient convenience are improved, but the device complexity increases
Solution Approach 1:
The guide pin is segmented into distinct functional portions: an insertion portion that penetrates the gingiva and reaches the alveolar bone, a guide portion that extends through the bone to the other side, and a tip that contacts the alveolar bone surface. This segmentation allows each portion to perform its specific function optimally while keeping the overall design relatively simple. The guide pin can be inserted through a small opening in the gingiva rather than requiring full incision, simplifying the surgical approach while maintaining operational effectiveness.

AI summary
Provided is a non-incisional dental implant surgical method, and more particularly, a non-incisional dental implant surgical method using a guide pin, whereby a dental implant surgery may be conducted accurately by easily determining an outer shape of an alveolar bone of a patient, into which an implant fixture is to be placed, when forming an implant hole in the alveolar bone and placing the implant fixture in the implant hole to place an implant in the alveolar bone of the patient.
