The aim of temporary retention is not to eliminate every causes of relapse and to ensure the stability of treatment, but to eliminate one cause of relapse: the periodontal reactions consecutive to the orthodontic displacement of teeth. The other causes of relapse must be eliminated by the treatment itself, and not by retention. To be effective the retention must be immediate, complete and prolonged. The most used temporary retainers are: the Hawley retainer, the vacuum-retainers and the bonded retainers. None of which is perfect. Only the permanent retention can ensure the stability whatever the cause of relapse. The risks of permanent retainers are not yet well known.
临时保持的目的不是消除复发的所有原因并确保治疗的稳定性，而是消除一个复发原因：牙齿正畸移动后的牙周反应。其他复发原因必须通过治疗本身而非保持来消除。要想有效，保持必须即刻、彻底且持久。最常用的临时保持器有：霍利保持器、真空保持器和粘结保持器。但它们都并非完美。只有永久性保持才能确保无论复发原因如何都能保持稳定。永久性保持器的风险尚不为人熟知。
