Removable partial denture interactive design method constructed based on vector graphics

Abstract

The invention relates to a removable partial denture interactive design method constructed based on vector graphics and solves the technical problems that in oral cavity diagnosis clinical practice atthe present stage, paper denture design sheets are prone to being damaged and lost, are not easy to store and manage and cannot provide structural data for follow-up reference use. The method comprises the following steps: (1) data definition and initialization: performing digital definition on a designed removable partial denture assembly and the position of the designed removable partial denture assembly and filling newly-built blank design with acquiescent digitized denture design data; (2) state switching: switching system drawing states according to a user operation; (3) drawing motion capture: capturing user mouse motion and modifying temporary drawing data to serve as response; (4) design rendering: reflecting user operation results through rendering; (5) motion capture finishing:capturing user mouse action and modifying formal drawing data to serve as response. The removable partial denture interactive design method disclosed by the invention can be applied to the field of partial denture design.

Description

Technical field [0001] The invention belongs to the field of computer graphics interaction, and particularly relates to an interactive design method for removable partial dentures based on vector graphics construction. Background technique [0002] Removable partial denture (RPD) is currently one of the main repair methods for dentition defects. It can use natural teeth and sub-base mucosa and bone tissue as support, rely on the retainer and base of the denture for retention, use artificial teeth to restore the shape and function of the missing teeth, and use base materials to restore the defective alveolar ridge And soft tissue morphology. In addition to a wide range of applications, it also has the advantages of small molar tissue, patients can remove and wear by themselves, easy to scrub and clean to maintain good oral hygiene, simple production method, low cost, easy maintenance and supplementation. Therefore, removable partial dentures are one of the most commonly used met...
