Three-dimensional evaluation of postoperative stability: a comparative study between surgery-first and surgery-late protocols

Surgery‐first in interdisciplinary class II cases

“…1,10 Orthodontic treatment was initiated 1 month after orthognathic surgery, partly taking advantage of the RAP and SAP which appear to be increased in the first 2 months after surgery. 1,3 The skeletal anchorage provided by the implants is an additional factor that might have shortened the treatment duration. One study analyzes the factors that play a role in the treatment duration, revealing that dental crowding, increased arch length discrepancy, anterior open bite, and requirement for orthodontic extractions implied a significant extension of treatment.…”

“…2,3,10 The preoperative orthodontic phase in the conventional orthognathic approach has the purpose of decompensating dental arches, aligning and leveling the occlusion. 1,3,7 From a psychological point of view, this is a very difficult phase for most patients, 4,6,8 negatively impacting their quality of life and often resulting in an aggravation of facial esthetics and dental function. 1,2,7 Due to the immediate perceived enhancements in facial appearance and shorter treatment length, a surgery-first approach might reveal higher rates of overall patients satisfaction, increasing their compliance and psychological wellbeing.…”

[1][2][3][4][5][6][8][9][10] The early correction of the skeletal problem could also represent a valuable solution for patients that suffer from sleep-disordered breathing, achieving immediate airway enlargement. [1][2][3]12 It is crucial to carefully select patients that are eligible for the surgery-first approach.…”

The recent technological advances in 3D imaging and simulation software provide a more accurate determination of the surgical and orthodontic movements 1,3,7,[13][14][15] and reduce the preoperative treatment planning time.…”
