With the improvement of the economic level and the advancement of medical resources, my country has begun to attach importance to oral health in recent years and has conducted oral epidemiological investigations. According to the results of the fourth national oral health epidemiological survey released by the National Health and Family Planning Commission, among the 65-74-year-olds, the number of remaining teeth is 22.5, which is 1.5 more than ten years ago; the proportion of full mouth without teeth is 4.5 %, a decrease of 33.8 percentage points from a decade ago; the rate of modified treatment for missing teeth was 63.2%, an increase of 29.5 percentage points from a decade ago. The rising level of consumption makes the demand for dentistry growing in old age.
 

    According to the survey results:

 
    In terms of dental caries (tooth decay), the caries prevalence among people aged 5, 12, 35-44, and 65-74 are 66%, 28.9%, 88.1%, and 98.4%, respectively.

 
    In terms of dental and jaw deformities, most of the dental and jaw deformities occur in the permanent dentition, and the prevalence is 72.97%. Followed by mixed dentition, the prevalence rate is 71.21%, and the prevalence rate of children's deciduous dentition is 51.84%.

 
    In terms of dental trauma, the proportion of children is slightly higher. 19.5% of 12-year-old students have experienced dental trauma in the past year.
 

The mature application of 3D printing in the dental field
 

    1. Implant surgery guide
 
    Implant surgical guides have achieved explosive growth with the current better aesthetics, cost savings, advances in CAD/CAM technology, and the support of 3D printing technology.
 

    2. High-precision tooth model
 
    Dental model scanning not only has extraordinary speed and high accuracy, texture scanning can enhance the visibility of surface details, can capture color marks that represent different design details, and adaptive scanning can also assist in achieving the purpose of natural occlusion.
 

    3. Movable denture base
 
    Use specific CAD software to realize 3D printing design of denture, including dental base, dental crown, dental bridge, dental crown, dental veneer, dental inlay, etc.

 
    3D printing company in action
 

Features:
 

DJ-89 has a larger molding size in similar equipment, and it can mold more than a dozen dental molds at one time. After the designer optimizes, it can be quickly formed in one day. It can be used in dental treatment, orthopedics, etc.

Using pionext's self-developed special resin material for dental molds, using light-curing DJ-89 printing, applied in the medical industry, high strength, high heat distortion temperature, and can meet the requirements of high-temperature steam sterilization

 
Pionext launches a new generation of light-curing 3D printers dedicated to dentistry

Since its establishment in 2015, pionext has continued to innovate in core technologies, patented technologies, and continuously upgraded its products. Pionext has been deeply involved in personalized medicine, automobile manufacturing, aerospace, personal applications and other fields in the 3D printing industry, and has deployed its products to more than 80 countries.

Pionext aims at the personalized medical market. Since its inception, it has developed dental-specific light-curing 3D printing products, which have been widely praised by partners such as clinics and denture manufacturers at home and abroad.

In April 2021, pionext released a new generation of high-precision 3D printer DJ-89 for dental health. This model is equipped with an 8.9-inch 4K ultra-high-definition monochrome screen designed for high-precision 3D printing. At the same time, it is equipped with pionext's second-generation patented liquid cooling technology, which has higher heat dissipation efficiency and can guarantee 5000 hours of stable and efficient printing.
 

 The planting impression scan program is officially released

The solution mainly solves the problem of low penetration rate of oral scans in the dental industry, and it is difficult for laboratories to quickly obtain patient oral data. The key application process can be divided into the following four steps:
 

    1: Get the tray
 
    Due to problems such as large undercuts, many tray impressions cannot be accurately scanned. The Heige impression screening jig independently developed by Heige can quickly detect the key areas of the impression and determine whether it can be scanned.
 

    2: Scanning data
 
    Use a scanner with a relatively high comprehensive scan rate on the market to scan and extract data. In order to ensure the accuracy of the impression scan, Haig Technology has further researched and produced a special scanning rod and a special substitute.
 

    3: Model design
 
    Use printer design software, or transfer data to Haig Design Center for design.
 

    4: 3D printing
 
    With the pionext series of dental 3d printer equipment, you can efficiently schedule production and quickly produce dental molds and guides.
 

 
    From a long-term perspective, the large-scale application of 3D printing in the dental industry is an inevitable trend. On the one hand, people are becoming more and more aware of dental health care, and they are willing to invest more money to beautify themselves. On the other hand, the talent training cycle is too long, and most of the licensed dentists rely on their personal experience for many years. Various dilemmas urge the injection of new technologies, and 3D printing technology will surely be the backbone of future dentistry.
