7 yrs. old child with early missing of D,E in both side in maxilla best space maintainer is.. Nancy appliance



7 yrs. old child with early missing of D,E in both side in maxilla best space maintainer is:

  • A. transpalatal
  • B. Nancy appliance
  • C. Band and loop
  • D. Lingual arch

For a 7-year-old child with early missing D and E (premolars) in both sides of the maxilla, the best space maintainer is most likely: C. Band and loop

Here's why:

- Age:

At 7 years old, the child is likely still in the mixed dentition, with some baby teeth present and some permanent teeth erupting.

- Missing teeth:

The missing teeth are the first premolars (D and E) on both sides of the maxilla.

- Space maintenance:

The goal is to maintain the space for the future eruption of the permanent premolars.

Advantages of a band and loop:

- Suitable for mixed dentition:

This type of space maintainer is well-suited for the mixed dentition, as it can be attached to the existing permanent first molars (bands) and extend a loop anteriorly to hold space for the erupting premolars.

- Simple and effective:

Band and loops are relatively simple to construct and use, making them a cost-effective option.

- Easy to maintain:

They are generally easy for children to maintain with good oral hygiene practices.

Other Options:

Why other options are less suitable:

A. Transpalatal:

This maintainer is typically used for more extensive space maintenance needs or when multiple teeth are missing bilaterally. It might be overkill for this specific scenario.

B. Nance appliance:

Similar to a transpalatal arch, this appliance is more suited for situations with broader space maintenance requirements.

D. Lingual arch:

This type of maintainer usually doesn't offer sufficient individual tooth control and is less commonly used in such situations.

Important notes:

It's important to note:
This information is for general knowledge only and should not be a substitute for professional dental advice.
The best course of treatment should be determined by a qualified dentist after a thorough examination of the child's individual case.
Factors like the child's specific needs, oral hygiene, and willingness to cooperate with the appliance will be considered when making the final decision.
