Rectangular Dental Implant Base for Periodontal Gap Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implants often result in food accumulation and trapping between the crown and adjacent teeth due to the round shape of implants not matching the square or rectangular geometry of missing teeth, leading to issues like tooth decay and adjacent tooth damage.
Innovation Solution
A dental implant system with a base member and abutment that are rectangular or square in shape, embedded within the jawbone to securely hold a crown, minimizing the gap between the crown and adjacent teeth, and featuring a central opening for an implant screw with a tapered head to prevent microleakage and enhance osseointegration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a round implant is used, then the implant can be easily manufactured and inserted, but food accumulates and traps between the crown and adjacent teeth due to geometry mismatch
Solution Approach 1:
The patent applies asymmetry by changing the implant geometry from round to rectangular or square, matching the geometry of adjacent teeth. This asymmetric shape eliminates the periodontal gaps that cause food trapping, while still allowing for relatively simple manufacturing processes.
2Reliability
If the base member is embedded within the jawbone recess, then stability and osseointegration are enhanced, but the surgical procedure becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-forming the recess in the jawbone with the exact dimensions and shape needed to receive the rectangular base member. This preliminary preparation simplifies the embedding process and ensures proper fit, reducing overall surgical complexity while maintaining high stability and osseointegration.
3Shape
If the top surface is angled relative to the bottom surface, then the crown is properly aligned with adjacent teeth, but the base member geometry becomes more complex
Solution Approach 1:
The patent applies local quality by creating an angled top surface only on the portion of the base member that contacts the crown, while keeping the sides and bottom suitable for embedding in bone. This localized angling achieves proper crown alignment without requiring complex geometry throughout the entire base member structure.

AI summary
A dental implant system includes a base member that is adapted to be embedded within a patient's jawbone at a treatment site. The base member has a generally flat top defining an outer periphery, a buccal side, a lingual side, a bottom, and a central opening. The lingual side or the buccal side is longer than the other. The base member is configured to be positioned within a recess in the patient's jawbone. An implant screw includes a head and a threaded end. The threaded end is adapted to pass through the central opening of the base member and into the patient's jawbone, and the head is adapted to be seated within the central opening of the base member after the threaded end is screwed into the patient's jawbone. An abutment is configured to be placed onto the top of the base member.
