Summary
Surgically repositioning an inverted impacted maxillary incisor toothgerm before root development offers a viable alternative to extraction. This approach promotes continued root formation and spontaneous eruption without complications.
Area of Science:
- Dentistry
- Oral Surgery
- Orthodontics
Background:
- Conventional orthodontic traction is often unsuitable for inverted impacted maxillary incisors near the alveolar crest.
- Limited space and root anomalies (short or dilacerated roots) contribute to a poor prognosis.
- Surgical repositioning of immature toothgerms presents a potential alternative to extraction.
Observation:
- A case report details the surgical repositioning of an inverted, impacted, immature maxillary incisor toothgerm in a 6-year-old boy.
- A closed-flap surgical technique was employed for the repositioning.
- The patient was monitored for 51 months post-surgery.
Findings:
- The repositioned toothgerm exhibited continued root formation.
- Spontaneous eruption of the maxillary incisor occurred following the surgical intervention.
- No pulpal or periodontal complications were noted during the follow-up period.
Implications:
- Surgical repositioning of inverted impacted incisor toothgerms is a promising treatment option.
- This technique can lead to successful root development and eruption.
- It avoids extraction and potential complications associated with conventional orthodontics.

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.

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...

01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
