Abstract:
Permanent molar loss is commonly encountered in clinical practice, and eruption of the opposing teeth caused by their prolonged absence increases the complexity of restorative treatment. How to rapidly and efficiently regain precise restorative space presents a clinical challenge. Orthodontic temporary anchorage devices (TADs) have been regarded as a minimally invasive treatment alternative with absolute anchorage and can simplify orthodontic intrusion. This digital technique aims to simulate the definitive restorative treatment outcome using a digital workflow that guides the design and 3-dimensional (3D) printing of a metal occlusal veneer with implant guides to intrude the target teeth. This intrusion system enables the precise control of the target tooth movement, thereby facilitating subsequent restorative treatment and ensuring a more favorable outcome.
