Partial Extraction Therapy Tooth Ring for Alveolar Ridge Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tooth extraction techniques, such as the Socket Shield method, are difficult for dentists to perform and traumatic for patients due to their complexity and potential for inadvertent damage, and they fail to adequately prevent alveolar ridge resorption, especially in posterior teeth where access is limited and root morphology is complicated.
Innovation Solution
A dental surgical method involving de-coronating the tooth, de-coring the coronal portion to create a tooth ring, severing and removing the apical portion of the tooth root, and optionally fixing an implant through the tooth ring to prevent alveolar resorption, using tools like Gates-Gliddon drills and a 'T' shaped bur to achieve a stable tooth ring for implant support or pontic crown foundation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Socket Shield technique is used to preserve buccal bone and gum, then alveolar ridge resorption is reduced, but the procedure becomes complex and traumatic with potential for inadvertent damage
Solution Approach 1:
The invention extracts and removes the problematic buccal root segment that causes resorption, rather than attempting to preserve it. By removing the root portion that extends into the bone and causing inflammation, the patent eliminates the source of alveolar ridge resorption without the complexity of attempting to preserve and protect it during implant placement.
Solution Approach 2:
Instead of preserving the buccal root segment as in the Socket Shield technique, the invention inverts the approach by removing it. This inversion simplifies the procedure by avoiding the complex steps of sectioning, levering, and securing root segments, while directly addressing the resorption problem through removal of the offending structure.
2Reliability
If the Socket Shield technique is used to support buccal bone, then bone preservation is improved, but the procedure is time-consuming and may be abandoned due to mobility of the shield
Solution Approach 1:
The invention removes the buccal root segment that causes bone resorption and procedural complexity, eliminating the need for time-consuming steps to section, secure, and position shields during the implant procedure.
Solution Approach 2:
The invention performs preliminary removal of the problematic root segment before implant placement, preventing resorption issues from arising during the surgical process and eliminating the need for complex shield stabilization steps.
3Reliability
If the Socket Shield technique is used on posterior teeth, then bone preservation is achieved, but access and root morphology make the procedure difficult to perform
Solution Approach 1:
The invention removes the buccal root segment that causes resorption, simplifying the procedure for posterior teeth where access is limited. By eliminating the need to preserve and position shields in hard-to-reach areas, the patent makes the procedure more feasible for posterior teeth while still addressing bone preservation through removal of the resorption-causing root portion.
4Reliability
If de-coronating and de-coring the tooth root is performed, then a stable tooth ring is created for implant support, but the procedure becomes more complex
Solution Approach 1:
The invention segments the tooth root into functional portions: the coronal tooth ring that remains for implant support and the apical root portion that is removed. This segmentation creates a stable tooth ring structure while simplifying the overall procedure by removing the problematic apical portion rather than attempting to preserve and protect the entire root structure.

AI summary
A method for preserving the alveolar ridge using partial extraction therapy. The method comprises de-coronating the tooth to leave a tooth root, de-coring a coronal portion of the tooth root to leave a tooth ring, severing an apical root portion of the tooth root from the tooth ring and removing the apical root portion. The tooth ring provides a ring of natural material that reinforces the coronal part of the tooth socket in the gum and reduces or obviates alveolar resorption.
