Abstract

Abstract:

BACKGROUND: The most effective treatment of mandibular prognathism is orthodontic-orthognathic surgical treatment, but the postoperative relapse is the common complication that influences the surgical effects. Based on the individual integral cranio-maxillo-facial structure, Delaire cephalometric analysis can establish the ideal cranio-maxillo-facial structure that can be applied to design the operative schemes thereby promoting postoperative stability.

OBJECTIVE: To analyze the stability and effect of orthognathic operations according to the schemes designed by Delaire cephalometric analysis.

METHODS: Twenty mandibular prognathism patients were subjected to the orthognathic operations designed by Delaire cephalometric analysis, to analyze their lateral cephalometric radiographs before operations, 6-8 months after operations and 12-16 months after operations. Then measurement data of 19 relevant items were measured and analyzed statistically.

RESULTS AND CONCLUSION: (1) There was no statistical significance in relapse of Go-Me and Go-LA after surgery; (2) The ∠Mp-F7 and ∠Op-F8 were reduced significantly after orthognathic treatment; (3) ∠F3-F7, ∠F4-F7 and ∠F7-F8 had no significant difference at these three time points; (4) ∠cc-SN was increased after orthognathic treatment. The results show that the orthognatic operations for mandibular prognathism patients guided by Delaire analysis can keep relative stability after treatment, the cranio-maxillo-facial structure can adapt to the new jaw morphology, and there is no obvious relapse after treatment.
