Embodiment 1
[0043] Embodiment 1 provides a kind of three-way analysis based on 3D printing to prepare the tooth guide plate design, this method comprises the following steps:
[0044] (1) Acquisition of digital models: By directly scanning the patient's mouth with an intraoral scanner, or scanning the patient's oral model / impression with a model scanner, a digital model of the oral condition is obtained, such as figure 1 Shown is the schematic diagram of the acquired digital model of the oral cavity.
[0045] (2) Virtually design the target restoration: after importing the obtained oral digital model, refer to the state of adjacent teeth, homonymous teeth, and opposing teeth in the current oral model to personalize the design of the teeth to be restored, and use the designed Target restorations and models are exported separately. Wherein, the target restoration refers to the restored tooth.
[0046] (3) Virtual assembly model and target restoration: import the designed target restoratio...
Embodiment 2
[0062] This embodiment provides a method for using a 3D printed tooth preparation guide plate in actual restoration. The 3D printed tooth preparation guide plate is produced by any of the methods in the foregoing embodiments. The use method specifically includes the following steps:
[0063] Step A. Place the prepared tooth preparation guide plate on the teeth in the patient's mouth.
[0064] Step B. Measure the gap between the tooth surface at the fixed depth hole position and the surface of the prepared tooth guide plate with a fixed depth bur. If the measured gap is greater than or equal to the minimum thickness of the future restoration material, no tooth removal treatment will be performed here; If the gap is smaller than the minimum thickness of the future restoration material, the tooth here will be removed, and the amount of tooth removal is the difference between the minimum thickness of the future restoration material and the measured gap.
[0065] C. According to th...
