Mandibular Bone Plate Multi-Surface Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mandibular bone plates with high profiles cause irritation to surrounding soft tissues and result in cosmetic deformities due to their attachment to the buccal and inferior surfaces of the mandible, leading to reduced performance and fatigue life.
Innovation Solution
A mandibular bone plate designed to attach to the buccal, lingual, and inferior surfaces of the mandible, featuring a curved chin portion with extension portions that allow for variable angle orientation, reducing palpability and improving anatomical fit, and utilizing a combination of bone anchor holes for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bone plate is attached to the buccal and inferior surfaces of the mandible, then the bone plate provides structural support and fixation, but the high profile of the plate causes irritation to surrounding soft tissues and cosmetic deformities
Solution Approach 1:
The bone plate is designed to attach to multiple surfaces of the mandible (buccal, lingual, and/or inferior surfaces) rather than being limited to traditional two-surface attachment. This multi-surface configuration distributes the plate's profile across different anatomical dimensions, reducing localized irritation to soft tissues while maintaining structural support and fixation strength.
2Adaptability or versatility
If the bone plate is adapted to facilitate anatomical placement, then the plate fits the mandible anatomy better, but the performance and fatigue life of the plate are degraded
Solution Approach 1:
The bone plate is divided into multiple segments or portions, each configured to attach to a specific surface of the mandible (buccal surface portion, lingual surface portion, and/or inferior surface portion). This segmentation allows each portion to be optimized for its specific anatomical location while maintaining the overall structural integrity and fatigue resistance of the complete plate assembly.
Solution Approach 2:
Different portions of the bone plate are designed with specific configurations optimized for their respective attachment surfaces. The plate includes features such as first bone anchor holes in a first portion and second bone anchor holes in a second portion, allowing localized optimization of fixation characteristics while preserving the global mechanical performance and fatigue life of the entire device.

AI summary
A mandibular bone plate (10) can include a body (40) that defines a bone facing surface (44), an outer surface (48) that is opposite the bone facing surface, and a plurality of bone anchor holes (52) that extend through the body from the bone facing surface to the outer surface. The body can include a chin portion (56) and first (60) and second (64) extension portions that extend from the chin portion such that the bone facing surface of the chin portion faces the inferior surface of the mandible when the mandibular bone plate is attached to the mandible and the bone facing surfaces of the first and second extension portions at least partially face the lingual surface of the mandible when the mandibular bone plate is attached to the mandible.
