Integrated Alveolar Bone Dilating Apparatus for Dental Implants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant procedures require multiple tools and processes, leading to inefficiencies and a risk of bone fracture due to concentrated pressure when expanding narrow alveolar bones for implantation.
Innovation Solution
An integrated alveolar bone dilating apparatus that combines a bone chisel and osteotome into a single tool, featuring a cylindrical grip, stopper, and a dilating part with an inverted conic shape and sharp blades for simultaneous incision and expansion of the alveolar bone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple tools (chisel, spreader, osteotome) are used to expand narrow alveolar bone, then the bone can be expanded, but the procedure becomes complex and time-consuming
Solution Approach 1:
The patent combines the functions of chisel, spreader, and osteotome into a single integrated tool. The tool features a grip portion, a stopper, and a dilating part with blades that can simultaneously perform incision and expansion functions, eliminating the need for multiple separate tools and reducing procedural complexity
Solution Approach 2:
The integrated tool is designed to perform multiple functions: the dilating part with blades can both incise the bone and expand it, while the stopper prevents over-expansion. This multi-functional design allows a single tool to replace multiple specialized tools, improving workflow efficiency
2Force
If great pressure is concentrated on one spot during bone expansion, then expansion force is sufficient, but lateral bone pieces may fracture
Solution Approach 1:
The dilating part is divided into multiple blades arranged in a specific pattern. These segmented blades distribute the expansion force across multiple contact points rather than concentrating it on a single spot, reducing the risk of lateral bone fracture while maintaining sufficient expansion capability
Solution Approach 2:
The blades are positioned to contact different regions of the bone at different angles, creating localized expansion forces that collectively achieve uniform bone widening without excessive stress concentration at any single point
3Productivity
If traditional chisel and spreader are used separately, then bone incision and expansion can be performed, but the procedure takes more time
Solution Approach 1:
The integrated tool allows the surgeon to perform both incision and expansion in a single operational step rather than requiring separate steps with different tools. The dilating part with blades can incise and expand simultaneously, significantly reducing procedure time
Solution Approach 2:
The tool design enables continuous action where the incision and expansion processes occur in an unbroken sequence without requiring tool changes or repositioning. The stopper ensures continuous controlled expansion while preventing over-expansion, maintaining efficient workflow

AI summary
Provided is an integrated alveolar bone dilating apparatus for dental implant. The apparatus includes a grip, a stopper, and a dilating part. The grip has a cylindrical shape. The stopper is disposed under the grip and has a diameter greater than a diameter of the grip. The dilating part is disposed under the stopper. Here, the dilating part includes a dilator reduced in diameter toward a lower portion thereof and having an inverted conic shape with a sharp tip, and two blades disposed on both sides of the dilator and being sharp toward the outside.
