Anchorage management is an important issue in orthodontic treatment and plays a big role in the success or failure of orthodontic treatment. Using a mini-implant system as skeletal anchorage is a suitable solution if maximum or absolute anchorage control is required. Applying mini-implants requires pinpointing their optimal position to prevent damaging adjacent anatomical structures. There are three considerations in locating proper mini-implant position: the point of implant insertion, the angle of implant insertion in the anterior-posterior direction, and the angulation of implant insertion in the vertical plane. Here, we illustrate a new three-dimensional mini-implant guide (Aleppo University Surgical Orthodontic Miniscrew Guide [AUSOM]) developed for determination of ideal mini-implant placement and demonstrate AUSOM's role in mini-implant success.
After reviewing of articles about mini-implants in orthodontic treatment, we determined the characteristics of an ideal orthodontic implant guide (IOIG). We invented a new instrument, AUSOM, that consists of four components: a horizontal part, a vertical part, a graduation guide, and film-holding part. Forty mini-implants were inserted for orthodontic treatment purposes; AUSOM and wire guides were used to insert the mini-implants.
We found AUSOM to be a practical and accurate device. It works as a radiographic-locating device and a mini-implant surgical placement guide. The failure rate of mini-implants placed by AUSOM was lower than that of those placed by simple metallic guides. Clinical randomized studies must be carried out to prove AUSOM's role in improving the success rate of mini-implant placement.
支抗管理是正畸治疗中的一个重要问题，对正畸治疗的成败起着重要作用。如果需要最大程度或绝对的支抗控制，使用微型种植体系统作为骨骼支抗是一个合适的解决方案。应用微型种植体需要精确确定其最佳位置，以防止损伤相邻的解剖结构。确定合适的微型种植体位置有三个考虑因素：种植体植入点、前后方向的种植体植入角度以及垂直平面内的种植体植入角度。在此，我们展示一种新的三维微型种植体导向器（阿勒颇大学外科正畸微型螺钉导向器 [AUSOM]），用于确定理想的微型种植体植入位置，并证明 AUSOM 在微型种植体成功植入中的作用。
在查阅有关正畸治疗中微型种植体的文章后，我们确定了理想正畸种植体导向器（IOIG）的特征。我们发明了一种新器械 AUSOM，它由四个部分组成：一个水平部分、一个垂直部分、一个刻度导向器和一个胶片固定部分。为正畸治疗目的插入了 40 枚微型种植体；使用 AUSOM 和钢丝导向器插入微型种植体。
我们发现 AUSOM 是一种实用且准确的装置。它可作为一种影像学定位装置和微型种植体手术植入导向器。使用 AUSOM 植入的微型种植体的失败率低于使用简单金属导向器植入的微型种植体。必须进行临床随机研究以证明 AUSOM 在提高微型种植体植入成功率方面的作用。
