To assess the functional needs of orthognathic patients treated in Isfahan University of Medical Sciences affiliated hospitals using the index of orthognathic functional treatment need (IOFTN).
A retrospective study was conducted using 2011-2015 records of 103 patients [58 female, 45 males, 16-45 years, mean (SD) age = 23.47 (6.44) years] who had orthognathic surgery. Malocclusion type (incisor classification), sagittal skeletal pattern (ANB angle), IOFTN score, and Dental Health Component of the IOTN [IOTN (DHC)] were recorded.
Overall, 92.2% and 82.5% of subjects scored 4 or 5 for IOFTN and IOTN (DHC), respectively, and no gender differences detected for both indices (P > 0.05). Gender differences detected for malocclusions/skeletal patterns (P < 0.05). Class III malocclusions (45.6%) and Class II skeletal patterns (51.5%) were the most prevalent type. Subjects with Class I, Class II, and Class III sagittal skeletal bases formed 4.8%, 51.5%, and 43.7% of the sample, respectively. IOFTN score of 5.3 (reverse OJ ≥ 3 mm, 27.2%) was the most prevalent, followed by 4.2(19.4%), 4.3(13.6%), 4.10 (12.6%), and 5.2 (8.7%). Subjects with Class III sagittal skeletal patterns or malocclusions had higher percentages of grade 5 IOFTN scores (62.2% and 59.6%), compared to Class II sagittal skeletal patterns or malocclusions (18.9% and 21.2%) and the distribution of functional needs between malocclusions or sagittal skeletal patterns were different (p < 0.01).
IOFTN identified 92.2% of orthognathic surgery patients as having great and very great functional needs and appeared to be reliable tool to identify patients in need of orthognathic surgery. Higher percentages of Class III subjects scored grade 5 of IOFTN, indicating higher functional need for orthognathic surgery in this group.
使用正颌功能治疗需求指数（IOFTN）评估在伊斯法罕医科大学附属医院接受治疗的正颌患者的功能需求。
采用回顾性研究，使用2011 - 2015年103例接受正颌手术患者的记录[58名女性，45名男性，年龄16 - 45岁，平均（标准差）年龄 = 23.47（6.44）岁]。记录错颌类型（切牙分类）、矢状骨面型（ANB角）、IOFTN评分以及IOTN的口腔健康成分[IOTN（DHC）]。
总体而言，分别有92.2%和82.5%的受试者IOFTN和IOTN（DHC）评分为4或5，且两个指数均未检测到性别差异（P > 0.05）。错颌/骨面型存在性别差异（P < 0.05）。III类错颌（45.6%）和II类骨面型（51.5%）是最常见的类型。I类、II类和III类矢状骨基的受试者分别占样本的4.8%、51.5%和43.7%。IOFTN评分为5.3（反覆盖≥3 mm，27.2%）最为常见，其次是4.2（19.4%）、4.3（13.6%）、4.10（12.6%）和5.2（8.7%）。与II类矢状骨面型或错颌（18.9%和21.2%）相比，III类矢状骨面型或错颌的受试者IOFTN评分为5级的百分比更高（62.2%和59.6%），并且错颌或矢状骨面型之间的功能需求分布不同（p < 0.01）。
IOFTN确定92.2%的正颌手术患者有很大和非常大的功能需求，似乎是识别需要正颌手术患者的可靠工具。III类受试者中IOFTN评分为5级的百分比更高，表明该组对正颌手术的功能需求更高。
