Problems solved by technology

Under the premise of lack of pre-preparation analysis design and clinical guidance, too deep restorative recess preparation violates the principle of preserving tooth tissue as much as possible and increases the risk of dental caries; too shallow restorative recess preparation makes the restorative recess Insufficient space in the position, causing the place to be placed becomes a weak point of force, and even interferes with the patient's occlusal movement

Embodiment 1

[0040] This embodiment discloses a method for manufacturing a guide plate for digitally and accurately guiding the preparation process of the support recess, including the following steps:

[0041] A. Construct a digital oral model based on the patient's oral data.

[0042] The patient's oral data can be obtained through an intraoral scanner or a desktop scanner after traditional impression taking. According to the obtained oral data, a corresponding digital oral model can be constructed using 3D modeling software. The construction of a digital oral model is as follows: figure 1 shown.

[0043] B. Prepare the rest recess 2 on the digital oral model.

[0044] Import the patient's digital oral model into the professional oral restorative design software, and complete the support at the corresponding position in the software according to the minimum depth and standard range required for the cobalt-chromium alloy rest recess (there are corresponding specifications in the field of...

Embodiment 2

[0059] This embodiment discloses a guide plate for digitally and accurately guiding the preparation process of the support recess, which is made by the manufacturing method of the first embodiment above.

Embodiment 3

[0061] This embodiment discloses the use method of the guide plate (hereinafter referred to as the guide guide plate) for digitally and accurately guiding the preparation process of the support recess in the second embodiment, including:

[0062] A. Position the positioning guide in the patient's mouth.

[0063] B. Fix a group of preparatory plug-in entities to the retaining post 3 of the positioning guide plate through their support columns. Under the guidance of the guide rings of the preparatory plug-in entities, the physician uses a matching preparatory bur (usually select a preparatory bur with scale) ) Prepare the rest recess on the area reserved on the positioning guide. Every time a set of support recesses 2 is prepared, the preparatory plug-in entity is replaced, and the next set of support recesses 2 is prepared, and the cycle is repeated until all support recesses 2 are prepared, as in Figure 7 shown.

[0064] C. Remove (the last group) the preparatory plug-in en...

Abstract

The invention discloses a guide plate for digitally and accurately guiding the preparation process of a support recess and a manufacturing method thereof. The guiding guide plate is composed of a support concave preparatory positioning guide plate and a preparatory plug-in entity. Through preoperative restorative concave preparation in the digital oral model, the guide ring data is obtained according to the custom bur, and then the preparatory insert is designed, and the preparatory insert and the positioning guide are combined and printed to obtain the guide guide. The guiding guide plate of the present invention can accurately guide the operation of clinically preparing the rest recess, so that doctors can obtain a predictable three-dimensional rest recess shape. Clinically, using this guide plate can complete accurate, fast and convenient restorative concave preparation, and reduce the number of visits of patients.

Description

technical field [0001] The invention relates to the technical field of oral surgery auxiliary tools, in particular to a guide plate for digitally and accurately guiding the preparation process of a rest recess and a manufacturing method thereof. Background technique [0002] Removable Partial Denture (RPD) has always been one of the essential repair methods in the field of oral restoration. It provides an economical and convenient treatment plan for patients with dentition defects, and has a wide range of indications. Only a reasonable RPD design can meet the coordination of soft and hard tissues, tooth position, and occlusal relationship to the greatest extent, and meet the patient's desire for restoration aesthetics and comfort. Steps that may lead to failure or complications due to clinicians’ negligence or lack of professional experience include: lack of prediagnostic planning, failure to prepare abutments; inability to adapt to the structure of RPD framework; lack of fo...
