Problems solved by technology

The preparation of removable partial denture brackets is a key link in the preparation of removable partial dentures. At present, the main processes include casting and subtractive material preparation. The casting process is complicated, and the applied materials are mostly metal materials, and their elastic modulus is much higher than that of human jaws. Bone, prone to stress shielding resulting in disuse resorption of bone
Subtractive material preparation is easy to cause waste of materials, and it is difficult to realize the design of relatively complex structures

Embodiment Construction

[0047] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0048] The design method of a personalized removable partial denture bracket of the present invention is specifically implemented according to the following steps:

[0049] Step 1. Place the need The tooth area of ​​the support is prepared; the preparation standard is specifically to prepare the occlusal surface of the tooth Support recess The width of the recess is 1 / 3 of the diameter of the cheek tongue of the molars, or 1 / 2 of the diameter of the cheek tongue of the premolars; The height of the support recess is 1.3~1.6mm; The length of the recess is 1 / 4 of the proximal and distal diameter of the molar, or 1 / 3 of the proximal and distal diameter of the premolar; the axis angle is rounded;

[0050] Step 2. Use 3Shape software to scan the patient's edentulous jaw to obtain the oral data of the patient's edentulous jaw; or prepare a plaster model based on the ...

Abstract

The invention discloses a design method for a personalized removable local dentures holder, two dentures holders designed by the design method, and a manufacture method for the two dentures holders. The design method is subjected to integral forming design, patient clinic doctor seeing frequencies are reduced, and patient and doctor time is saved. The two designed dentures holders are both subjected to the integral forming design, and the problem of more dentures components in the prior art can be solved. The manufacture method is subjected to integral forming manufacture, and therefore, the problems in the prior art that a casting technology has a complex and complicated manufacture process and subtractive manufacturing materials can not be fully utilized can be solved.

Description

Technical field [0001] The invention belongs to the technical field of removable partial denture bracket design, and specifically relates to a design method of a personalized removable partial denture bracket, two kinds of denture brackets designed by using the design method, and a manufacturing method of the two kinds of denture brackets. Background technique [0002] Removable partial denture uses the remaining natural teeth, bone tissue and the mask under the base as a support, relies on the retainer and base of the removable denture for retention, and uses artificial teeth to restore the patient’s missing teeth. Column repair method. The preparation of removable partial denture scaffolds is a key link in the preparation of removable partial dentures. At present, the main processes include casting and material reduction preparation. The casting process is complex, and most of the applied materials are metal materials, and its elastic modulus is much higher than that of human j...
