Alveolar Bone and Epithelial Attachment Status following Two Different Closed-eruption Surgical Techniques for Impacted Maxillary Central Incisors: A Recent Study | Chapter 7 | New Frontiers in Medicine and Medical Research Vol. 16

 Aim: There are two basic surgical techniques for the treatment of upper impacted central incisors (ICIs): open and closed. Because it delivers the best cosmetic and periodontal benefits, the closed-eruption surgical approach (CEST) is currently the most preferred. The goal of this study was to see how removing traction affected the sulcal depth and alveolar bone ridge levels of maxillary central incisors as compared to contralateral incisors when CEST was utilised.

Materials and Procedures: CEST was utilised to treat 28 maxillary central incisors that were unilaterally impacted. Thirteen teeth were subjected to a month of traction interruption at the time of crown emergence, while 15 teeth were subjected to continuous traction. One year after treatment, periapical digital X-rays, anterosuperior cone beam computed tomography (CBCT) scanning, and periodontal probing were performed on the ICIs and contralateral central incisors (CCIs). The Student's t-test was used to evaluate if there was a statistically significant difference between continuous and interrupted tractions, using the CCI data as a reference.

Only mesial probing (p-value 0.039352), labial bone level (p-value 2.58E-08), and palatal bone level (p-value 2.58E-08) indicated a statistically significant difference between the two procedures (p-value 2.56E-06).

Limitations: A bigger sample size and longer-term follow-up are necessary to draw more solid results.

Conclusion: On ICIs, a brief break during tooth traction appears to increase treatment results. Better treatment outcomes can be achieved by making technical changes and using a short interruption during tooth traction.

Clinical relevance:

• The withdrawal of traction at the emergence of the tooth permits the supracrestal fibres to properly enter into the cement, resulting in the optimal periodontal condition for ICIs.
