Orthognathic Surgery: Participants in the experimental group will undergo orthognathic surgery
Study summary
Orthognathic surgery leads to changes in the three-dimensional position of the jaws, which may result in alterations in head and neck posture as well as overall body posture. These postural changes are also expected to influence plantar pressure distribution. This study aims to evaluate the direction and magnitude of these changes by assessing posture and plantar pressure measurements before and after orthognathic surgery.
Postural analysis and plantar pressure measurements will be performed preoperatively and at the 6-month postoperative follow-up in patients undergoing orthognathic surgery. In order to allow a reliable comparison, a control group consisting of non-operated individuals will also be included. The range of natural changes observed in the control group will be determined, and the outcomes will be compared between the surgical and control groups.
By comparing preoperative and postoperative measurements, this study aims to evaluate the effects of orthognathic surgery on body posture and plantar pressure distribution. The findings are expected to contribute to the identification of parameters that should be considered in postoperative evaluation and rehabilitation. Furthermore, the results will provide valuable information regarding the postural and plantar pressure changes observed in patients following orthognathic surgery.

Inclusion Criteria:
* Study Group (Orthognathic Surgery Group)
Participants will be eligible for inclusion in the surgical cohort if they meet all of the following criteria:
Individuals scheduled to undergo single-jaw or double-jaw orthognathic surgery as part of comprehensive orthodontic treatment.
Currently receiving orthodontic therapy utilizing clear aligner systems or fixed orthodontic appliances.
Availability of preoperative lateral cephalometric radiographs obtained as part of routine clinical evaluation.
Age ≥ 18 years at the time of enrollment.
Completion of a minimum of 6 months of postoperative orthodontic treatment, enabling standardized follow-up evaluation.
Body Mass Index (BMI) \< 30 kg/m², to minimize confounding effects related to obesity on postural and plantar pressure measurements.
Control Group (Non-surgical Group)
Participants will be eligible for inclusion in the control cohort if they meet all of the following criteria:
Individuals not undergoing orthognathic surgery during the study period.
Receiving orthodontic treatment with clear aligners or fixed appliances, comparable to the surgical cohort.
BMI \< 30 kg/m².
Age ≥ 18 years.
No participation in physical activities or rehabilitative programs that may alter postural parameters or plantar pressure distribution during the study period.
Exclusion Criteria:
* Participants from either cohort will be excluded if they exhibit:
Neuromuscular, musculoskeletal, or postural disorders that may independently influence balance or plantar pressure distribution.
History of previous orthognathic or maxillofacial surgery.
Systemic diseases affecting bone metabolism, neuromuscular function, or gait.
Pregnancy.
Inability or unwillingness to comply with study procedures or follow-up assessments.
Primary outcome measure(s)
Change in Plantar Pressure Distribution — Baseline and 6 months postoperative Plantar pressure distribution will be evaluated using static and dynamic pedobarographic measurements. Peak plantar pressure, pressure distribution patterns, and contact area will be recorded preoperatively and at 6 months postoperatively to assess changes in plantar loading following orthognathic surgery.
