Commonly Used Types of Dental Digital Equipment

In the field of modern oral healthcare, the use of digital equipment is changing the traditional treatment model at an unprecedented rate. These advanced devices not only improve the accuracy of diagnosis and precision of treatment, but also bring patients a more comfortable and efficient medical experience. The following are several commonly used oral digital equipment.

I.Oral digital scanning equipment

Also known as “oral three-dimensional scanning equipment”, is the digital process of data input link.

1. Model scanner

Three-dimensional scanning equipment designed for the dental industry, used to obtain accurate three-dimensional data of dental models or impressions, usually need to be associated with other design software.

(1) Application

Applicable to all kinds of oral fixed denture, movable denture digital design and production requirements (Average scanning speed of about 16 seconds for the whole arch, three-in-one scanning about 33 seconds, scanning accuracy of about 5-15μm).

(2) Advantages

② Light source is mostly structured blue light. 

2. Intraoral scanning equipment

Through the small optical scanning head into the patient's oral cavity, directly on the surface morphology of soft and hard tissues such as dental mucosa scanning, real-time reconstruction of the scanning area of the three-dimensional digital model, a step to obtain the digital dental models. 

II.Oral digital cutting equipment

According to the number of motion axes that can be controlled by its numerical control system, it can be divided into three-axis, four-axis, five-axis, etc.

1.Application

Can be used for cutting implant personalized abutments, metal crowns and bridges, zirconia crowns and bridges, glass ceramics, etc.

2.Advantages

② Is the first choice for batch denture production, processing speed. 

III.The oral digital 3D printer 

1. Principle

Through the discrete process of three-dimensional digital model into a two-dimensional model of the continuous superposition of layers, and then controlled by the computer program, in order to build up the material layer by layer forming process

2. Advantages

① Overcome the limitations of the removal processing technology, can be batch produced in a relatively short period of time, a variety of complex forms of models (such as: RPD brackets, full denture wax-up, implant guides, etc.)

② Complex oral restorations and medical devices can be manufactured quickly and accurately. Whether it is dental models, implant guides or orthodontic appliances, it can do it easily.

③ It realizes the minimum consumption of raw materials from the principle, and the raw materials (resin liquid, metal powder, etc.) that have not been processed by shaping can be reused and reused, which greatly reduces the cost of denture materials, and it has now become the mainstream way to digitally batch fabricate metal-base crowns and bridges.
