Abstract:
This article outlines the orthodontic treatment of a 21-year-old female patient with an open bite and temporomandibular joint disorders (TMDs) that developed after a severe car accident. The treatment plan utilized temporary anchorage devices (TADs) for upper molar intrusion to correct the open bite without resorting to orthognathic surgery. Over a period of 3 years, the treatment achieved a stable occlusion, normalized molar relationships, and improved esthetics. Despite the persistent of TMD symptoms, the patient experienced enhanced jaw movement and a reduction in abnormal chewing cycles. The combination of orthodontic treatment with TADs and splint therapy contributed to successfully restoring both esthetic and functional aspects. This case underscores the efficacy of TADs in addressing trauma-induced malocclusions, highlighting the potential for minimal intervention to achieve comprehensive treatment outcomes.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
