Summary
This study presents a nonextraction orthodontic treatment for maxillary canine and first premolar transposition. The successful correction established a Class I relationship, with bone regeneration observed post-treatment.
Area of Science:
- Orthodontics and Dental Traumatology
- Maxillofacial Surgery
- Periodontology
Background:
- Maxillary canine-premolar transposition is a common orthodontic challenge.
- Traditionally, correction is not recommended after permanent tooth eruption.
- Recent literature explores nonextraction fixed mechanics for transposition correction.
Observation:
- A case of complete transposition between a maxillary left canine and first premolar is described.
- Fixed orthodontic mechanics were employed for nonextraction treatment.
- Computed tomography (CT) revealed triangular cortical bone resorption at the canine root's vestibule post-treatment.
Findings:
- Successful correction of the transposed teeth was achieved.
- A functional Class I canine and molar relationship was established.
- Post-retention CT scans showed spontaneous bone tissue regeneration in the resorption area.
Implications:
- Nonextraction fixed mechanics offer a viable treatment option for maxillary canine-premolar transposition.
- The findings suggest potential for spontaneous bone regeneration following orthodontic intervention.
- This approach may provide an alternative to extraction or surgical interventions for complex tooth transpositions.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
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 and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
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 grinding food.
