Malocclusions with midline shift, large overjet, and deep overbite are linked to temporomandibular disorders (TMD). Orthodontic treatment planning for severe malocclusions must consider temporomandibular joint status.
Area of Science:
- Orthodontics
- Craniofacial Biology
- Temporomandibular Joint Disorders
Background:
- Malocclusions are common dental conditions.
- Temporomandibular disorders (TMD) affect the jaw joint and muscles.
- Understanding the craniofacial skeletal patterns associated with TMD in malocclusion patients is crucial.
Purpose of the Study:
- To determine the skeletal patterns in individuals with malocclusions and TMD.
- To investigate the relationship between craniofacial skeletal structures and TMD in malocclusion patients.
Main Methods:
- Sixty-four adult subjects with malocclusions were analyzed.
- Temporomandibular disorders were assessed using the Helkimo Anamnestic Index.
- Lateral cephalograms were used to evaluate skeletal patterns, grouped by sagittal classification (ANB angle).
Main Results:
- Subjects with TMD exhibited a broader midline shift and Wits appraisal across all skeletal classes.
- A larger overjet was observed in the TMD group.
- Frequent TMD symptoms included joint noises, reduced mandibular mobility, muscular pain, and temporomandibular joint (TMJ) pain.
Conclusions:
- The status of the temporomandibular joint (TMJ) is a significant consideration in orthodontic treatment planning for severe malocclusions.
- Specific malocclusion features like midline shift, increased overjet, and deep overbite are associated with TMD signs and symptoms.

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Bone Markings
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
