Mini-screws, also known as temporary anchorage devices (TADs), offer enhanced control and versatility in orthodontic treatment by providing stable anchorage points. This clinical study aims to evaluate the effectiveness of mini-screw-supported molar intrusion in orthodontic practice. For this clinical study, a cohort of 40 orthodontic patients with various malocclusions requiring molar intrusion as part of their treatment plan was recruited. The age range of the participants spanned from 14 to 35 years, representing a diverse patient population. The intervention involved the implementation of mini-screw-supported molar intrusion on one side of the maxillary arch in each patient. To achieve this, temporary mini-screws were strategically placed, and a combination of orthodontic forces and mini-screw anchorage was employed to intrude the molars. The primary outcome measure for this study was the amount of molar intrusion achieved, which was quantified in millimeters from the initial evaluation to the final visit. Additionally, the duration of treatment required to achieve the desired molar intrusion was recorded in months. The results of this clinical study demonstrated that mini-screw-supported molar intrusion was an effective and safe orthodontic technique. On average, a significant mean molar intrusion amount of 4.8 mm (standard deviation [SD] ± 0.6) was achieved with the mini-screw-supported approach. Furthermore, the treatment duration required to attain the desired molar intrusion was relatively short, with a mean of 6.2 months (SD ± 1.1). In conclusion, this clinical study provides evidence that mini-screw-supported molar intrusion is an effective and safe approach in orthodontic practice. It offers orthodontists the advantage of enhanced control and predictability in molar intrusion procedures.
微型螺钉，也被称为临时锚固装置（TADs），通过提供稳定的锚固点，在正畸治疗中提供了更强的控制能力和多功能性。本临床研究旨在评估微型螺钉支持的磨牙压低在正畸实践中的有效性。在这项临床研究中，招募了40名患有各种错颌畸形且治疗计划中需要压低磨牙的正畸患者。参与者的年龄范围为14至35岁，代表了不同的患者群体。干预措施包括在每位患者的上颌牙弓一侧实施微型螺钉支持的磨牙压低。为实现这一点，有策略地放置临时微型螺钉，并采用正畸力和微型螺钉锚固相结合的方法来压低磨牙。本研究的主要结局指标是实现的磨牙压低量，从初始评估到最终复诊以毫米为单位进行量化。此外，记录实现所需磨牙压低所需的治疗时间，以月为单位。这项临床研究的结果表明，微型螺钉支持的磨牙压低是一种有效且安全的正畸技术。采用微型螺钉支持的方法，平均实现了显著的磨牙压低量，为4.8毫米（标准差[SD]±0.6）。此外，实现所需磨牙压低所需的治疗时间相对较短，平均为6.2个月（SD±1.1）。总之，这项临床研究提供了证据，表明微型螺钉支持的磨牙压低在正畸实践中是一种有效且安全的方法。它为正畸医生在磨牙压低程序中提供了更强的控制能力和可预测性优势。
