Rectangular Dental Implant Base Reducing Food Impaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tooth implant designs with a round base portion lead to enlarged embrasures between the implant and adjacent teeth, causing food impaction and accumulation, resulting in gingival inflammation and gum infection, requiring frequent removal of debris by patients.
Innovation Solution
A tooth implant with an enlarged, generally rectangular base that distributes load better on the jawbone and reduces embrasures by having a base attachment screw with a threaded end for anchoring, allowing the crown portion to have more upright peripheral sidewalls and a matingly configured top and bottom portion for proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a round base portion is used in the implant, then the implant can be anchored securely in the jawbone, but the embrasures between the implant and adjacent teeth are enlarged, causing food impaction and accumulation
Solution Approach 1:
The patent applies asymmetry by changing the base shape from round to rectangular. The rectangular base has four sides that can be configured to match the rectangular opening between adjacent teeth, creating a better fit that minimizes embrasures while maintaining anchoring security through the threaded engagement with the jawbone
2Object-affected harmful factors
If the base is enlarged to reduce embrasures, then food impaction is reduced, but the load distribution on the jawbone needs to be improved
Solution Approach 1:
The rectangular base shape provides both reduced embrasures and improved load distribution. The four-sided configuration allows the base to contact the jawbone at multiple points around the implant site, distributing mechanical loads more effectively than a round base while simultaneously minimizing the embrasures where food could become impacted
3Ease of manufacture
If the crown portion has a round bottom portion, then it can seat on the retaining screw platform, but the peripheral sides taper from rectangular upper to round base, creating enlarged embrasures
Solution Approach 1:
The patent applies asymmetry by making the bottom portion of the crown rectangular to match the rectangular base, eliminating the transition from rectangular upper to round base. This creates parallel vertical sides that maintain a consistent width from top to bottom, minimizing embrasures and preventing food impaction while remaining manufacturable
Solution Approach 2:
The patent applies local quality by configuring only the critical interface portions (base and crown bottom) with rectangular geometry to minimize embrasures, while the upper crown portion can maintain aesthetic shapes. This localized geometric optimization solves the food impaction problem without compromising the overall crown design or manufacturing feasibility

AI summary
A dental implant system in one embodiment is constructed of a base member that is to be embedded within a patient's jawbone. This base member has a central opening that tapers inward from a top surface to a bottom surface. The system also includes an implant screw haying a head and a threaded end which passes through the central opening of the base member and into the patient's jawbone. The head has a tapered section to seat within the tapered opening of the base member. In this way, the base member is secured to the jawbone while the base member is embedded within the patient's jawbone. A crown is provided to be coupled to the implant screw.
