Controlled Release Dental Anesthetic Socket Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing post-operative dental pain rely heavily on narcotics and self-administration of local anesthetics, which pose risks of overdose and adverse effects, and existing sustained release formulations do not effectively coordinate with pre-surgical doses to prevent these issues.
Innovation Solution
A solid controlled release pharmaceutical formulation of local anesthetics is placed in the dental socket after tooth extraction, designed to release anesthetic in coordination with pre-administered local anesthetics, providing sustained pain relief for 4 to 5 days without the need for narcotics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If narcotics are used to manage post-operative dental pain, then pain relief is effective, but serious side effects occur including addiction, respiratory depression, and cardiac arrest
Solution Approach 1:
The invention extracts the harmful element (narcotics) from the pain management system by replacing it with a local anesthetic delivery system. The controlled release formulation delivers anesthetic directly to the surgical site, eliminating the need for systemic narcotic administration while maintaining effective pain relief.
Solution Approach 2:
The invention introduces a controlled release formulation as an intermediary between the local anesthetic and the patient's pain receptors. This intermediary system provides sustained delivery of the anesthetic agent directly at the surgical site, avoiding the need for narcotic intermediaries that cause harmful side effects.
2Duration of action of moving object
If additional local anesthetics are administered post-surgery, then pain relief is extended, but the risk of overdose increases due to additive effects with pre-surgical doses
Solution Approach 1:
The invention applies preliminary action by administering the controlled release formulation immediately during surgery, coordinated with the pre-surgical local anesthetic dose. The formulation is designed to begin releasing anesthetic as the initial dose wears off, preventing gaps in pain relief while avoiding dangerous accumulation through controlled release kinetics.
Solution Approach 2:
The controlled release formulation provides periodic action by delivering the anesthetic in a controlled, time-dependent manner. The release profile is designed to match the declining levels of pre-surgical anesthetic, creating a coordinated periodic delivery pattern that extends duration while maintaining safe concentrations.
3Productivity
If long duration local anesthetics are used to reduce administration frequency, then the number of doses is reduced, but rapid onset creates substantial risk of overdose when combined with pre-surgical doses
Solution Approach 1:
The invention applies dynamics by using a controlled release formulation that adjusts the release rate of the anesthetic over time. The formulation provides sustained delivery without rapid onset, creating a dynamic release profile that extends duration while maintaining safe concentrations throughout the delivery period.
4Ease of operation
If patient self-administration of local anesthetics is allowed, then convenience is improved, but safety deteriorates due to inability to time administration properly and risk of overdose
Solution Approach 1:
The controlled release formulation provides self-service functionality by automatically delivering the anesthetic at the appropriate time and rate without patient intervention. The formulation eliminates the need for patient timing decisions while maintaining convenient availability, as the drug delivers itself in a controlled manner over the desired period.

Function Achieved in This Case
This approach reduces the risk of overdose and adverse effects by coordinating the release of the second anesthetic with the decline of the first, providing prolonged pain relief without the use of narcotics, thus enhancing patient safety and comfort post-surgically.
