Abstract
Background
The surgery-first approach (SFA) to orthognathic treatment aims to reduce its duration
without compromising the outcome. However, the objective assessment of the achieved
occlusion has been limited.
Objective
To assess the treatment duration, outpatient appointment number, and quality of occlusal
outcome for two groups of patients; one treated with the SFA and the other with an
orthodontics-first approach (OFA).
Method
Retrospective cohort study of case records for twenty consecutive SFA, and 23 consecutive
OFA, cases with class III malocclusions, treated with Le Fort 1 maxillary osteotomy
only. Pre-and post-treatment study models were assessed using the Peer Assessment
Rating (PAR).
Results
Significant differences (p<0.001) were found between the median active treatment durations
(10.2 months for the SFA and 32.5 months for the OFA) and appointment numbers (14
for SFA and 24 for OFA). Median absolute PAR reductions were 40 for the SFA and 39
for the OFA. There was no significant difference between the groups regarding quality
of occlusal correction.
Conclusions
Treatment durations for the SFA group were significantly shorter than for the OFA
group, with fewer outpatient appointments. The quality of occlusal outcome for both
SFA and OFA groups were satisfactory and comparable.
