Application prospect of hybrid reality technology in stomatology

With the continuous development of computer technology, image display technology, spatial positioning technology and force feedback technology, more and more research began to focus on the integration of virtual space and real space, so that the observer can experience a special mixed environment. Its core is to break the boundary between the virtual world and the real world through digital technology Hybrid reality technology is a new digital holographic image technology after virtual reality technology and augmented reality technology. Its core characteristic is to break the boundary between virtual world...
Research progress of new orthodontic arch wire

Research progress of new orthodontic arch wire

Orthodontic elastic arch wire, rubber band, permanent magnet and muscle contraction force are the main sources of orthodontic force. As the most important source of orthodontic force, orthodontic arch wire has attracted much attention in orthodontic treatment. The interaction between orthodontic arch wire and bracket directly affects the treatment effect, cycle and stability after treatment In addition, with more and more adult patients choose orthodontic treatment, people's requirements for the aesthetic performance and biological safety of orthodontic appliances are becoming more and more prominent, which makes the high efficiency, aesthetics...

[worth collecting] dental clinical data that dentists must know!

Numbers make people feel concrete and reflect things accurately In prosthodontics, the following numbers may make your medical treatment more effective Data show that When the temperature of pulp cavity increased by 4.1 ℃, 15% pulp necrosis occurred When the temperature was increased by 8.2 ℃, 60% of the pulp was necrotic When the temperature of pulp cavity increased to 51.7 ℃, all pulp necrosis occurred In normal condition, the free gingival margin is about 0-2mm from the gingival margin to the gingival sulcus base, and there is a 2mm...
Direct bonding restoration of anterior teeth with composite resin

Direct bonding restoration of anterior teeth with composite resin

The main factors to be considered are the color and texture of the materials, while the functional properties such as strength and wear resistance are the second factors From the current development of dental materials, combined with the gradually mature enamel, dentin bonding technology and resin, porcelain and metal bonding technology, composite resin material has both aesthetic characteristics and more durable, which is the most able to meet the above requirements in clinical practice Composite resin direct bonding restoration is suitable for the restoration of anterior teeth tissue defects (I,...
Market demand analysis of different types of fixed prosthesis

Market demand analysis of different types of fixed prosthesis

Recently, Yu Na, Ma Chaoyi and Yue Li from the Department of Prosthodontics, West China College of Stomatology, Sichuan University, jointly published a paper to explore the market demand and demand changes of different types of fixed prostheses This study pointed out that porcelain fused to metal (PFM) restorations occupy the dominant position in the market demand. The output of Ni Cr alloy PFM restorations decreased year by year and was gradually replaced by CO Cr alloy PFM. The output of fixed restorations fluctuated seasonally. Therefore, resource allocation should be...
Restoration of anterior teeth with alumina infiltrated all ceramic crown

Restoration of anterior teeth with alumina infiltrated all ceramic crown

Case 1 Basic information and clinical examination of patients A 33 year old female patient had been restored with metal ceramic crowns for many years. Because of the poor appearance of the porcelain fused to metal crown, was required to be removed for all ceramic crown restoration. The clinical examination before restoration of showed that 11 metal edges were exposed, gingival margin was stained black, and gingiva was red and swollen (Fig. 1); The results showed that the restoration effect of 11 of incisor defect was similar to that of...

Discussion on digital restoration of crown and Bridge

Discussion on digital restoration of crown and Bridge

Tooth is one of the most vulnerable organs in human body. Its fragility is manifested in the absence of any self-healing function. In prosthetic treatment, we must emphasize preservation and minimally invasive. The development of digital stomatology requires more and more dentists' skills. The successful application of digital technology is based on the operation of doctors Up to now, there is no technology that can replace the doctor's clinical operation. Oral treatment still depends on the doctor's exquisite operation and fine technology. If the doctor's operation is not up to...
Chen Zhi: review of composite resin restoration technology for posterior teeth

Chen Zhi: review of composite resin restoration technology for posterior teeth

Evidence based medical evidence suggests that physicians should inform patients of the life expectancy of the restorations before treatment, especially when the teeth with high risk of caries and patients with multiple surface restorations are directly filled with composite resin This evidence-based medical evidence was a meta-analysis conducted by Dutch scholars. 12 related literatures were included in the study, a total of 2816 restorations were included in the study, of which 569 failed in the observation period. Regression analysis showed that the main cause of failure was secondary caries and...
