Bone Condensation Drill Bit for Single-Rotation Osteotomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drill bits fail to efficiently create debris and direct it towards the tip while simultaneously compressing it into the sidewall of a hole during bone drilling, leading to inadequate support for implants in low-density bone.
Innovation Solution
A drill bit design featuring a helical flute and land area that directs debris longitudinally toward the tip and laterally compresses it into the sidewall during a single direction rotation, enhancing bone density for implant stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a drill bit rotates in two directions to perform osteotomy, then cutting capability is improved, but bone condensation and debris compression are insufficient
Solution Approach 1:
The patent combines two previously separate operations (drilling and bone condensation) into a single integrated process. The drill bit performs both cutting and compression functions during rotation in one direction, eliminating the need for separate condensation steps and improving overall reliability of the osteotomy procedure.
Solution Approach 2:
The drill bit is designed with multi-functionality, serving both as a cutting tool and a compression device. The helical flute structure simultaneously removes debris and compresses bone material into the hole sidewall, allowing one tool to perform multiple functions that previously required separate operations.
2Productivity
If debris is not compressed into the sidewall, then drilling speed is maintained, but implant stability in low-density bone is insufficient
Solution Approach 1:
The patent converts the harmful effect of debris accumulation (which can interfere with implant stability) into a beneficial effect. By designing the helical flute to compress debris into the sidewall, the previously problematic bone chips become a means to strengthen the bone structure and improve implant anchorage in low-density bone.
Solution Approach 2:
The patent changes the physical state and distribution of bone debris through compression. The debris is transformed from loose particles into a compacted structure within the hole sidewall, altering its density and mechanical properties to enhance implant stability without compromising drilling speed.
3Ease of operation
If a single direction rotation is used for drilling, then operation simplicity is improved, but debris removal and compression cannot be achieved simultaneously
Solution Approach 1:
The patent introduces dynamic functionality to the drill bit through the helical flute design. The rotating helical structure creates dynamic motion that simultaneously transports debris toward the tip while applying compression forces against the sidewall, enabling multiple functions during simple single-direction rotation.
Solution Approach 2:
The helical flute adds a dimensional aspect to debris management. Instead of simple linear removal, the helical geometry creates a spiral path that combines axial transport with radial compression, allowing debris to be moved and compressed simultaneously through the three-dimensional helical motion during rotation.

Function Achieved in This Case
The design achieves simultaneous drilling and bone condensation, creating a denser structure to support dental or bone implants by compressing debris into the sidewall, improving implant stability in low-density bone.
Implementation Method 1
a helical flute and a land area configured to direct the debris toward the tip and compress the debris into a side wall of a hole during rotation in a single direction
Implementation Method 2
the first land area compresses the debris laterally outward from the drill bit into a side wall of a drill hole during rotation of the drill bit in a single direction

AI summary
A drill bit configured to simultaneously direct debris toward a drill bit tip and compress the debris into a sidewall of a hole during rotation in a single direction to strengthen the hole to receive an implant. The drill bit may comprise an osteotome, the hole may comprise an osteotomy, and the implant may be a dental implant. In an example, due to the right-hand (clockwise) rotation of the drill bit, a helical flute exhibits an apparent counterclockwise movement relative to a stationary observer, commonly referred to as apparent flute motion. The drill bit is configured to simultaneously direct the created debris longitudinally toward the tip while the first land area compresses the debris laterally outward from the drill bit into a side wall of a drill hole during rotation of the drill bit in a single direction.
