Widely used, especially for supra-implant solutions, the indication of attachments is now extended to orthodontics. The objective of this series of cases was to describe three clinical situations in which attachments on miniscrews have been adapted to orthodontics, leading to the development of a new connection: the ball attachment or Ball Abutment making it « semi removable » anchoring devices which until now had to be fixed. A series of three cases is presented. For each case, the miniscrew(s) already in place during the active orthodontic treatment phase is (or are) used with a palatal device (palatal plate or palatal expander). In the latter case, the Ball Abutment, of relatively simple use, is fixed over the miniscrews allowing the device to offer controlled looseness. This attachment allows the clinician to put in place space-saving devices promoting the retention of the devices, at the border between the fixed and the removable device, sometimes less bulky and more discreet, particularly for adult patients. They could be part of lingual technique treatments. Tests are necessary to assess this orthodontic device in terms of materials, design and retention. This connection offers a new range of possibilities and design of semi-removable passive devices that increase the multifunctionality of miniscrews during treatment.
附件的应用广泛，尤其适用于种植体上方的解决方案，目前其应用范围已扩展至正畸领域。本系列病例的目的是描述三种临床情况，即微螺钉上的附件已被应用于正畸治疗，从而开发出一种新的连接方式：球形附件或球形基台，使其成为“半可摘式”锚固装置，而在此之前此类装置必须是固定的。本文展示了三个病例。对于每个病例，在积极的正畸治疗阶段已植入的微螺钉与腭部装置（腭板或腭扩展器）配合使用。在后一种情况下，使用相对简单的球形基台固定在微螺钉上，使装置具有可控的松动度。这种附件使临床医生能够设置节省空间的装置，促进装置的固位，处于固定装置和可摘装置之间的边界，有时体积更小、更隐蔽，尤其适用于成年患者。它们可以成为舌侧技术治疗的一部分。有必要对这种正畸装置在材料、设计和固位方面进行测试。这种连接方式为半可摘被动装置提供了一系列新的可能性和设计，增加了微螺钉在治疗过程中的多功能性。
