Dental Bone Foundation Guide With Lingual Gap for Guided Implant Placement
Solution Overview
Problem
Current dental surgical systems face challenges in efficiently creating a flat bone foundation for prosthetic placement, particularly in full dental arch restorations, due to the need for extensive bone remodeling and the complexity of aligning implants correctly.
Innovation Solution
The use of a bone foundation guide with a palatal or lingual side gap, in combination with a strut assembly and surgical guide, allows for precise alignment and drilling of implant passageways, facilitating the creation of a flat bone foundation and ensuring accurate placement of prosthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional bone remodeling procedures are used to create a flat foundation for prosthetic placement, then the prosthetic can be properly seated, but the surgical procedure becomes complex and time-consuming
Solution Approach 1:
The surgical guide is designed and fabricated before surgery based on pre-operative imaging (CT scans and digital impressions). The guide incorporates predetermined drill guide holes and bone reduction indications that are calculated in advance using software, allowing the surgeon to follow a pre-planned approach rather than making complex decisions during surgery.
Solution Approach 2:
The surgical guide acts as an intermediary device between the digital treatment plan and the actual surgical execution. It translates the virtual plan into physical guidance on the patient's anatomy, using guide pins, drill guides, and bone reduction indicators to ensure precise implementation without requiring the surgeon to mentally process complex spatial relationships during the procedure.
2Manufacturing precision
If traditional bone remodeling procedures are used, then prosthetic placement is enabled, but the surgical time and procedure duration increase
Solution Approach 1:
All measurements, calculations, and treatment planning are completed before surgery using specialized software that processes CT scans and digital impressions. The surgical guide is fabricated in advance with all necessary drill guide holes and bone reduction markings predetermined, eliminating time-consuming intraoperative measurements and calculations.
Solution Approach 2:
The surgical procedure is divided into distinct, guided steps: (1) positioning the surgical guide on the cast, (2) inserting guide pins through predetermined holes, (3) drilling implant sites following the guide, and (4) performing bone reduction according to marked indications. This segmentation allows each step to be executed quickly and efficiently without requiring complex decision-making during the procedure.
3Reliability
If extensive bone remodeling is performed to create a flat foundation, then prosthetic seating is improved, but the surgical complexity and difficulty increase
Solution Approach 1:
The surgical guide serves as a mediator that simplifies the surgical operation by providing physical guidance through drill guide holes and bone reduction markings. The guide ensures that bone remodeling is performed precisely where needed to create the necessary flat foundation, eliminating the need for the surgeon to perform complex mental spatial transformations during the procedure.
Solution Approach 2:
The system replaces complex manual bone remodeling techniques with a guided approach using the surgical guide. Instead of requiring the surgeon to manually create and maintain a flat bone surface through skill-intensive techniques, the guide provides predetermined indications for bone reduction, transforming a complex mechanical skill into a simpler follow-the-guide procedure.

AI summary
A first guide member includes a horizontal body portion and a pair of upright portions. The horizontal body portion has an arcuate configuration and includes a first horizontal surface, a front surface, a rear surface, and a second horizontal surface. The first horizontal surface is flat. The first upright body portion includes a first inwardly extending portion. A first engagement surface of the first inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The second upright body portion includes a second inwardly extending portion. A second engagement surface of the second inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The first guide member lacks a component configured to extend along a lingual or palatal side of the alveolar arch of the patient.
