Orthodontic treatment often faces challenges in achieving proper anchorage. While orthodontic mini-implants have gained popularity, no universally accepted design and insertion protocol exists for these implants. However, their relatively modest failure rate indicates their clinical reliability. To address complex geometries in the maxilla and mandible, patient-specific implants (PSIs) have emerged as a solution. PSI is currently employed in various domains of oral and maxillofacial surgery like temporomandibular joint (TMJ), total joint replacement, reconstruction of the facial skeleton, and orthognathic surgery. PSI allows for the creation of customized implant fits, leading to shorter rehabilitation times. This case report presents a multidisciplinary approach involving oral surgery and orthodontics, specifically focusing on the design of PSI, surgical placement of PSI, and use of PSI in maxillary protraction in orthodontics. The report highlights the design process of designing PSI and emphasizes its role in orthodontic treatment. By incorporating PSI as a temporary anchorage device (TAD), enhanced stability, precise control over tooth movement, and accurate repositioning of jaws can be achieved. The collaborative effort between orthodontists and oral surgeons is crucial in integrating PSI into the overall treatment plan. Despite the higher costs associated with PSI, their numerous advantages outweigh these drawbacks. PSI plays a vital role in providing enhanced stability, appropriate treatment plan, and achieving desired treatment in orthodontic and oral surgery procedures.
正畸治疗在实现适当的支抗方面常常面临挑战。尽管正畸微型种植体已广受欢迎，但对于这些种植体，尚无普遍接受的设计和植入方案。然而，它们相对较低的失败率表明了其临床可靠性。为了解决上颌骨和下颌骨复杂的几何形状问题，患者特异性种植体（PSI）应运而生。目前，PSI已应用于口腔颌面外科的各个领域，如颞下颌关节（TMJ）、全关节置换、面部骨骼重建和正颌外科手术。PSI能够实现定制化的种植体适配，从而缩短康复时间。本病例报告展示了一种涉及口腔外科和正畸科的多学科方法，特别关注PSI的设计、PSI的手术植入以及PSI在正畸上颌前牵引中的应用。该报告突出了PSI的设计过程，并强调了其在正畸治疗中的作用。通过将PSI用作临时支抗装置（TAD），可以实现更高的稳定性、对牙齿移动的精确控制以及颌骨的准确复位。正畸医生和口腔外科医生之间的协作对于将PSI纳入整体治疗计划至关重要。尽管PSI相关成本较高，但其众多优点超过了这些缺点。PSI在正畸和口腔外科手术中对于提供更高的稳定性、制定合适的治疗方案以及实现预期治疗效果起着至关重要的作用。
