Cylindrical Dental Implant Abutment for Healing and Direct Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant procedures face issues with healing abutments having salient points causing tongue irritation and require separate scan heads, leading to tissue growth and inflammation, and prolonged procedure times.
Innovation Solution
A cylindrical abutment with a smooth surface and known dimensions is attached to the implant root, serving as both a healing abutment and scan head, allowing direct scanning during osseointegration, eliminating the need for a separate scan head and reducing tissue irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional hexagonal healing abutment is used, then the abutment can be engaged with a wrenching tool and screwed into the implant, but the salient points cause tongue irritation and tissue inflammation
Solution Approach 1:
The patent combines the healing abutment and scan head into a single integrated component. The abutment features a smooth cylindrical exterior that serves both as a healing abutment and as a scan head with known dimensions for digital scanning, eliminating the need for separate components and removing the salient points that cause irritation
Solution Approach 2:
The abutment is designed to perform multiple functions: it serves as a healing abutment during the osseointegration period, as a scan head for digital scanning to capture oral anatomy data, and as a reference object for scaling scan data. This multi-functionality eliminates the need for separate scan heads and reduces the number of procedures required
2Measurement precision
If a separate scan head is attached after healing, then scanning can be performed, but the procedure time is prolonged and additional tissue manipulation is required
Solution Approach 1:
The abutment is designed with known dimensions and scan-friendly features before the healing process begins. This preliminary design allows the abutment to serve as an immediate scan head once attached to the implant, eliminating the need for a separate scanning procedure and reducing overall treatment time
3Measurement precision
If the healing abutment is removed before scanning, then a scan head can be attached, but the procedure becomes more complex and time-consuming
Solution Approach 1:
The patent merges the healing abutment and scan head functions into a single component. The abutment features a smooth cylindrical exterior with known dimensions that can be directly scanned, eliminating the need for separate scan heads and reducing the number of components and procedures required

AI summary
A system and method for implanting a prosthetic tooth in a patient having an intraoral tooth gap. The gingival tissue in the tooth gap is opened to expose a section of jawbone. An implant root is installed into the jawbone. An improved abutment is attached to the implant root. The improved abutment has a cylindrical body. The improved abutment extends a first height above the tooth implant and into the tooth gap. The gingival material is closed around the improved abutment to enable the gingival material to form and heal around the improved abutment. The improved abutment is mapped in the tooth gap to produce a dimensional map, wherein the known dimensions of the improved abutment provide scale to the dimensional map. An implant crown is fabricated using the dimensional map.
