Hubungan Tinggi Wajah terhadap Tekanan Plantar Kaki pada Pasien Underweight Maloklusi Klas I Skeletal

Abstract

Postural balance is associated with craniofacial growth, particularly in children with a low body mass index, such as those who are underweight. Being underweight can affect facial development and the distribution of foot plantar pressure, which plays a role in maintaining postural stability. This study aimed to determine the relationship between facial height and foot plantar pressure in underweight patients with skeletal Class I malocclusion. This descriptive-analytic study was conducted using a cross-sectional approach at RSGM USU. The sample consisted of 55 children aged 10–15 years with a body mass index (BMI) below 18.5 and a diagnosis of skeletal Class I malocclusion. Facial height was measured using Jarabak analysis through the WebCeph® application, while foot plantar pressure was measured using a body mass balance detector (IDS000009315). The results showed that the majority of subjects had normal foot plantar pressure (85.5%), and the most common type of facial height was normodivergent (45.5%). The chi-square test indicated no significant relationship between facial height and foot plantar pressure (p > 0.05). This study concluded that there is no significant relationship between facial height and foot plantar pressure in underweight patients with skeletal Class I malocclusion. Variations in malocclusion and BMI should be considered in future research.
