Purpose:
To compare the clinical efficacy of the conventional double puncture versus single puncture type 2 arthrocentesis for management of temporomandibular joint disc displacement without reduction (DDWOR).
Materials And Methods:
Twenty-six patients with DDWOR were randomly and blindly allocated into two treatment groups (N = 13): Group 1, conventional double puncture arthrocentesis; Group 2, single puncture type 2 arthrocentesis. Data on gender, side of painful joint complaint, age (years), duration of joint pain (months), maximum interincisal distance (MID - mm), and pain intensity self-reported with a visual analog scale (VAS; 0-10) were collected. VAS scores and MID were measured before (baseline) and 6 months after arthrocentesis (final).
Results:
Both techniques resulted in significantly reduced VAS scores and increased MID (p = 0.001) after 180 days. However, there were no statistically significant differences between techniques (p > 0.05).
Conclusions:
The two arthrocentesis methods tested were effective in reducing VAS scores and increasing MID in patients with DDWOR.

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...
Structural Joints: Cartilaginous Joints
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
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.
