The inability to adapt matrix bands successfully to badly broken down teeth has been a source of frustration to clinicians. Unfortunately, this has often led to therapy involving extractions of strategic posterior teeth because the dentist thinks that the time and effort entailed in restoring the tooth is not practical, or that an attempt to band a difficult tooth would prove futile. The banding technique described here was effective after proper enclosure, length, and gingival adaptation were accomplished, and the occlusal surface of the crown was removed; the technique can make a difficult procedure easier to accomplish.
临床医生在将矩阵带成功应用于严重破损的牙齿时面临的困难一直是他们沮丧的来源。不幸的是，这常常导致需要拔除关键的后牙进行治疗，因为牙医认为修复牙齿所需的时间和精力不切实际，或者尝试为一颗难以操作的牙齿安装带环会被证明是徒劳的。这里描述的带环技术在完成适当的包绕、长度调整和牙龈贴合，以及去除牙冠的咬合面后是有效的；该技术可以使一个困难的操作更容易完成。
