Study on the multi‐manipulator tooth‐arrangement robot for complete denture manufacturing

Purpose – It is not an easy and simple task to manufacture a complete denture with high quality. Traditionally, it often needs a medical expert with experience and hand‐on skill, due to the manual way of denture manufacturing. The purpose of this paper is to implement the multi‐manipulator tooth‐arrangement robot system that can fully automate the denture manufacturing process.Design/methodology/approach – A novel complete denture manufacturing mechanism is designed, which is based on the multi‐manipulator and dental arch generator. The visual tooth‐arrangement and robot control software is developed in VC++6.0. Preliminary experiments on tooth‐arrangement have been conducted using the proposed multi‐manipulator tooth‐arrangement robot prototype system.Findings – The multi‐manipulator tooth‐arrangement robot prototype system can automatically design and manufacture a set of complete denture that fit a patient by visual tooth‐arrangement and robot control software according to the patients jaw arch parame...Purpose – It is not an easy and simple task to manufacture a complete denture with high quality.

Design/methodology/approach – A novel complete denture manufacturing mechanism is designed, which is based on the multi-manipulator and dental arch generator. The visual tooth-arrangement and robot control software is developed in VCþþ6.0. Preliminary experiments on tooth-arrangement have been conducted using the proposed multi-manipulator tooth-arrangement robot prototype system. Findings – The multi-manipulator tooth-arrangement robot prototype system can automatically design and manufacture a set of complete denture that fit a patient by visual tooth-arrangement and robot control software according to the patient’s jaw arch parameters. Research limitations/implications – The implication of research is that it is feasible that the manufacture strategy of complete denture fulfilled by multi-manipulator tooth-arrangement robot. The limitation of research is that it is difficult to realize coordinate control. Originality/value – The traditional manual method which makes complete denture by medical personal experience will be changed after the multi-manipulator tooth-arrangement robot system is manufactured, and adjustment to each tooth position and orientation will be realized by this system.

Implementation of glass-curtain-wall cleaning robot driven by double flexible rope

Purpose – The purpose of this paper is to implement a glass-curtain-wall cleaning robot driven by a double flexible rope, so as to replace manual cleaning. The glass-curtain-wall, because of its excellent daylighting performance, damp-proofing characteristics, heat insulation properties and aesthetics, is widely used in modern city buildings. For glass-curtain-wall buildings, regular cleaning of the glass-curtain-wall is necessary to ensure that the surface of the building appears clean and tidy, which in turn contributes toward preserving the overall aesthetic appearance of the city. Currently, the primary method of cleaning glass curtain walls is manual cleaning by workers on a suspended platform. Design/methodology/approach – The mechanical structure of the proposed glass-curtain-wall cleaning robot driven by a double flexible rope is inspired by the way a spider moves by pulling its silk draglines in the air. For self-locking protection and increased rope friction, the robot’s moving section includes ...

Springback mechanism analysis and experimentation of orthodontic archwire bending considering slip warping phenomenon

Malocclusion is a common oral disease. Fixed appliance technology is the most common and effective malocclusion orthodontic treatment method, and the key step of fixed appliance technology is the bending of orthodontic archwire. Because the slip warping phenomenon exists in the process of orthodontic archwire bending, it is difficult to realize rapid and accurate bending of the customized orthodontic archwires. A bending springback mechanism model considering the slip warping of the archwire in the process of bending is established. The influence of the slip warping phenomenon of the archwire between the fixed mold and the rotation mold is considered in the analysis of the springback mechanism. The bending process of archwire is divided into two stages: elastic deformation and plastic deformation, based on the variety of the bending radius in the bending process. A springback mechanism model of the orthodontic archwire is established. The springback mechanism model of the orthodontic archwire is analyzed and compensated based on the characteristics of the robot structure. An archwire bending experiment is carried out to verify the correctness of the springback mechanism model of the orthodontic archwire.
