Margin of Error01:27

Margin of Error

5.0K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

Area of Science:

  • Dentistry
  • Restorative Dentistry
  • Periodontal Surgery

Background:

  • Managing localized subgingival margins presents challenges in tooth preparation for various restorations.
  • Existing techniques may require invasive procedures.

Purpose of the Study:

  • To present an evolution of the deep margin elevation technique.
  • To introduce the matrix-in-a-matrix technique for improved subgingival margin management.

Main Methods:

  • Utilizing a modified circumferential matrix for local isolation of deep margins.
  • Implementing the matrix-in-a-matrix technique with a sectional band and Teflon tape.

Main Results:

  • The matrix-in-a-matrix technique enhances isolation and fit of subgingival matrices.
  • This modified deep margin elevation facilitates ideal conditions for scanning or impression making.

Conclusions:

  • Deep margin elevation, particularly the matrix-in-a-matrix technique, offers a less invasive solution for subgingival margin challenges.
  • This approach can potentially prevent the need for resective surgeries, invasive restorative procedures, or extractions.
