Summary
This study presents a protocol for treating bilateral temporomandibular joint (TMJ) ankylosis using intraoperative navigation and custom joint prostheses. The method aims for accurate and repeatable single-stage surgical correction.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Bilateral temporomandibular joint (TMJ) ankylosis presents significant surgical challenges.
- Single-stage treatment requires precise execution to avoid complications.
- Intraoperative navigation enhances safety and efficiency in complex joint surgeries.
Purpose of the Study:
- To establish a protocol for single-stage surgical correction of bilateral TMJ ankylosis.
- To utilize intraoperative navigation for improved accuracy and safety.
- To validate the use of intermaxillary fixation screws and custom prostheses for TMJ total joint replacement.
Main Methods:
- Development of a surgical protocol for bilateral TMJ ankylosis correction.
- Implementation of intraoperative navigation for real-time identification of vital structures.
- Verification of custom joint prosthesis site preparation using navigation.
- Use of intermaxillary fixation screws for precise joint positioning.
Main Results:
- The proposed protocol facilitates a faster and safer excision of ankylosed tissue.
- Intraoperative navigation aids in accurate identification of critical anatomical structures.
- Navigation confirms appropriate site preparation for custom TMJ prostheses.
- The protocol aims for accurate and repeatable outcomes in single-stage total joint replacement.
Conclusions:
- A standardized protocol integrating intraoperative navigation and intermaxillary fixation screws can achieve accurate and repeatable results for bilateral TMJ ankylosis.
- This single-stage approach offers a viable solution for complex TMJ reconstruction.
- Intraoperative navigation is a valuable tool for enhancing precision and safety in TMJ total joint replacement surgery.

01:16Structural Joints: Synovial Joints
7.3K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

01:03Structural Joints: Fibrous Joints
3.9K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

01:17Structural Joints: Cartilaginous Joints
4.2K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable

01:30Method of Joints
1.3K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...

00:58Introduction to Joints
4.9K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...
