How serious is the situation of malocclusion in China?
The fourth national oral health sample survey data show that malocclusion detection rate is as high as 91.5%.
According to a Scorch Consulting report, China's orthodontic market will grow from $3.4 billion in retail sales in 2015 to $7.3 billion in 2019, a CAGR of 20.7%, and is expected to reach $29.6 billion in 2030, a CAGR of 13.6%.
Behind this, is the enhancement of people's consumer awareness, oral health, oral beauty consciousness. In this context, the demand for oral healthcare will continue to rise. If the dental track is a crown on the capital market (check price | model details), then orthodontics must be considered one of the most shining pearl.
(These problems are not only a threat to oral health
The impact on appearance, mental health is also quite large)
Orthodontics can adjust the patient's facial image, to improve the function of mastication, so that the face is more beautiful, the mouth is more healthy. Oral orthodontics refers to the continuous application of gentle external force to the teeth in a specific direction by means of an orthodontic device to adjust the coordination between the facial bones, teeth, and the nerves and muscles of the maxillofacial region, in order to achieve the goal of balance, stability, and aesthetics of the oral and maxillofacial system. The main malocclusions treated include, crowding of teeth, gap dentition, proclination, malocclusion, and so on. Orthodontics is highly beneficial and consumable in enhancing the quality of life of patients with malocclusion.
With the gradual increase in patient demand for orthodontic treatment in terms of aesthetics and comfort, orthodontic technology has evolved rapidly, resulting in the birth of Invisible Bracketless technology. It has the characteristics of comfort, transparency, aesthetics, high efficiency, etc., changing the traditional orthodontic teeth appeared? The wire and iron teeth? The phenomenon, widely favored by orthodontic patients, so that people no longer have a rejection of oral correction.
Invisible orthodontic treatment was first introduced in 1998 in the United States, the use of safe and transparent elastic polymer material made of invisible aligners treatment, compared with the traditional fixed aligners, without brackets and wires, clinical operation is greatly simplified, the orthodontic process saves time and effort, and can be completed the whole treatment process in the unnoticeable bystanders, without affecting daily life and social life.
Invisible Oral Care is a new type of orthodontic treatment that is designed to provide the best possible results. Invisible Orthodontics is a new science and technology in the field of dentistry, breaking the limitations of the traditional orthodontic treatment, outstanding advantages, has been in the orthodontic clinical application for more than 20 years. It opens up a new direction of orthodontic digital treatment and precision treatment, and this technology provides a brand new treatment method for the majority of orthodontic patients, which is different from the traditional fixed orthodontic technology.
In 2004, our scholars developed a diagnostic and treatment system for invisible orthodontic treatment without brackets with independent intellectual property rights in China, which opened up the research and development and clinical application of this technology in the field of dentistry in China, and had a positive role in promoting its subsequent application and development in China.
With the bracketless invisible orthodontic technology has been more and more widely used at home and abroad, more and more brands of products, and a rapid increase in the number of completed cases. However, at present, there is a lack of uniform standards in the selection of indications, clinical diagnostic and treatment procedures, efficacy evaluation and analysis of this technology. The Orthodontic Committee of Chinese Orthodontics Association has formed an expert group, combined with the clinical experience of domestic orthodontic counterparts and a wide range of opinions, and has written and completed The Guide to Orthodontic Invisible Bracketless Orthodontic Technique, which establishes the standards for the selection of indications, clinical diagnostic and treatment procedures, and analysis of efficacy evaluation, providing references for the majority of orthodontists to carry out the Invisible Bracketless Orthodontic Technique.
Part1
What are the risks involved in the application of Invisalign?
Socketless invisible orthodontic technology and traditional fixed orthodontics, there are also a variety of orthodontic complications, the most likely derailment phenomenon caused by the following three reasons:
1, the invisible aligner material performance differences in the impact
2, the patient's own individual differences in the impact
3, the invisible aligners, the teeth move with the teeth during the process of orthodontic treatment, and the teeth are not the same as the teeth. The movement of teeth in the process of orthodontic treatment deviates from the computer preset
Sub-risk reduction recommendations:
a)? Invisalign is a removable appliance, the treatment process depends on the patient's cooperation, and good compliance is a prerequisite to ensure good treatment results of Invisalign
b)? For some complex tooth movement, restarting the treatment or using fixed appliances and other assistive devices may be required during the treatment process to achieve good treatment results
c)? Must be professionally trained and qualified orthodontic specialists and qualified manufacturers
Part2
Indications for and selection of bracketless invisible orthodontic technology?
The guideline categorizes predictable cases into high, medium, and low, with corresponding requirements for the level of expertise of the practitioner.
1. Highly predictable cases are those in which the simulated orthodontic goals can be precisely achieved.
a)? Cases where the clinical crowns are of sufficient height to ensure good retention of the appliance;?
b)? Cases of mild crowding in which the amount of bone is not adjusted by ?4mm and can be relieved by using a 2-4mm labiobuccal distal-medial expansion arch;?
c)? Anchor Class I extraction cases with tooth-volume-bone-volume disproportion>8mm and severe crowding;
d)? Closure of <4mm of scattered gaps;?
e)? Extraction of lower incisors;
f) Dental anticuspension
g) I-II deep overlap
2. Moderately predictable cases requiring treatment by a practitioner with some experience in invisible trayless orthodontics in order to accurately achieve the goal of simulated orthodontic treatment.
a) Class II deep overlap
b) Cases in which the posterior teeth are moved no more than 4mm distally and centrally;
c) Cases in which the posterior teeth are moved no more than 4mm distally and centrally.
c) Treatment requiring intermaxillary traction;
d) ? Cases with loosening of teeth I and above;
e) Mildly open anterior teeth
f) Moderately open anterior teeth
3. Low predictable cases, cases that require treatment by practitioners with extensive experience in both invisible and fixed orthodontic treatment in order to accurately achieve simulated orthodontic objectives.
a)? Cases with severe twisting of premolars and mandibular cusps;
b)? Bimaxillary anterior protrusion requiring extractions for internalization of deep overlays
c)? Premolar extraction cases that require anterior removal of posterior teeth by more than 2 mm;?
d)? Cases with insufficient clinical crown eruption height;?
e)? Cases requiring combined orthodontic-orthognathic treatment.?
The guideline recognizes that the range of cases that can be treated with bracketless invisible orthodontic techniques will gradually expand as materials science develops and technology advances. However, for a number of reasons, including the lack of use of individual tooth center of resistance information and the different rates of alveolar bone remodeling in different individuals, the selection of indications should not only start with the wrong The guideline strongly discourages beginners from treating low-predictability cases with bracketless invisible orthodontic technology.
Part3
What are the requirements for the collection of case data for Invisalign?
It is captured in 3 main ways.
1. Routine collection surface
2. Imaging data collection?
a)? Surface tomography: used to comprehensively observe the number of teeth, the development of tooth germs, but also to assess the tilt of the tooth axis, the presence or absence of the third molar, the two sides of the condyle and the symmetry of the jaws, etc.
b)? Lateral cephalometric film: used to clarify the teeth,
c)?CBCT: can be taken if necessary, a comprehensive assessment of the patient's temporomandibular joints and upper and lower anterior teeth in the basal bone
3, the acquisition of digital models?
a)? Silicone rubber impression taking?
b)? Digital intraoral scanner to obtain dental information?
Detailed information about the dentition and gingiva can be obtained using a silicone rubber impression or a digital intraoral scanner, and a digital model can be created for model analysis, treatment planning, and prediction of treatment outcomes.
Part4
What is the design process for an Invisalign program?
The design process consists of 6 main areas.
1. Digital simulation design of a series of tooth movement, including the judgment of the appropriateness of the final target position of tooth movement, and the reasonableness of step-by-step movement in the tooth movement process.
