1. The production process of full zirconia crowns
The production and treatment process of traditional crowns must go through grinding, impression (this stage is the most uncomfortable), delivery to the laboratory (it takes more than a week), and finally the braces can be put on. If there are any mistakes or Adjustments are required, and the back and forth will take more time (many people take more than a month to complete the course).
The full zirconia crowns and braces used in high-end dental clinics are assisted by digital technology, which not only makes the production of porcelain teeth more accurate, but also makes the whole treatment more efficient, allowing patients to replace the new full zirconia in the shortest time.
2. High-precision microscope equipment
In addition to the precise and fast crown/braces manufacturing process, the ultimate manual post-processing by professional dental technicians and high-precision microscopic equipment must be added to make each ceramic tooth as delicate as a work of art.
To have the best results of porcelain teeth, you must first have a tooth preparation. The so-called tooth preparation means that in order to allow the full-ceramic crown or veneer to be installed, the teeth must be properly ground first, and tooth preparation needs to have Clinically experienced dentists and sophisticated equipment can do it perfectly: only when the teeth are well ground, can we have good results when making porcelain teeth later. Poor tooth preparation (grinding) and improperly fitted porcelain crowns will make the teeth prone to second-degree cavities, etc. Better clinics are equipped with high-magnification microscopes and use expensive diamond needles for fine grinding so that the grinding of teeth preparation and porcelain teeth can have better results.
3. Dental scanning methods and equipment
Dentists in high-end clinics introduced German digital scanning equipment to replace the traditional impression method, which is not easy to affect the accuracy due to external factors, and the information obtained by digital analysis can be used as a reference for dental technicians in designing the occlusal point of porcelain teeth so that porcelain teeth are more accurate. durable.
4. Whether the dental technician is integrated into the clinic
Unlike in the past, the dental crown was outsourced to a laboratory for production, now the full-ceramic crown design center is set up in a dental clinic so that the dentist who knows the patient’s condition best can communicate directly with the dental technician. Whatever patient needs regarding chewing functionality or aesthetic design can be discussed and corrected immediately.
5. Full zirconia crown glazing technique
“Implant braces” are the real needs of the entire dental implant treatment patient. The treatment itself is indeed to restore the aesthetic or functional needs, but the patient’s need is not to implant something, but to get back the lost teeth.
The common way of making dental implants is the cooperation between a dentist and a dental technician. After implanting the patient’s teeth, the professional dentist can obtain the patient’s dental model after the bone grows stably and the abutment teeth are installed. For dental technicians, if digital 3D scanning is used, dental technicians can see the patient’s gingiva, surrounding tissue, occlusal status and other information on the digital model magnified 22 times, and then use “AI software-aided design” and “high-definition”. After grinding with a scientific and technological grinder, the prototype of the dental implant braces was made. The dental technician then uses skillful hands to carve, burn pottery, and dye to shape the final dental implant.
Inside a tooth, there are actually three separate layers. The top layer is what we call the crown. The middle layer, acting as the neck of the implant, connects the “implant” locked into the alveolar bone and the uppermost “crown”, is called “abutment” precisely. Let’s take a look at the material differences of dental implants from here:
The “implant” in the alveolar bone must be a pure titanium implant with a certificate from the Department of Health and high bio-compatibility, which can not only improve the success rate of dental implantation but also be less prone to adverse side effects. The feeling of a doctor choosing a dental implant is like finding a house where you can live permanently.
There are so many brands of dental implants, how to choose? Where is the difference? In the implant brand selection skills, dentist uses the perspective of “buying a house” to easily understand the importance of implants.
The “abutment body” that is placed in the implant to support the mouthpiece upwards also needs to have high bio-compatibility. Because the material placed in the gum will directly contact the gingival tissue around the implant, the tissue will grow around this part. Otherwise, the gum and other tissues will not grow well, and the implant will easily become inflamed or fail. The biocompatibility of materials is very demanding. There are mainly several materials in dentistry that can achieve this goal, titanium metal, zirconia or all-ceramic materials, and these alloy materials are the first choice for abutments.
The “crown” placed on the gum needs to be both beautiful and endurable.
- Zirconia: It can not only be used in abutments but also can continue to be applied in crowns due to its high occlusal strength, such as full zirconium crowns that are often seen on the Internet. At present, there are many brands of zirconia, and the mainstream ones are American, Japanese, German, Korean, Taiwanese, and Chinese. People can ask the clinic for relevant information to understand the source of zirconia materials used in their dental implants. The manufacturing process of zirconia must be produced through “digital design, grinding, and printing”. Dental laboratories usually need to invest in higher equipment costs to make zirconia crowns.
- Lithium disilicate: This material is widely used, its strength is lower than ordinary zirconia but more aesthetic, and the long-term follow-up treatment results are also very good. Like zirconia, lithium disilicate also has different prices depending on the place of origin, and is mainly suitable for the aesthetic area of anterior teeth.
- Metal: Dental implant braces can also be made of complete metal. Commonly used ones are titanium alloy braces, palladium alloy braces, etc., which are equally stable in use, but are mostly used in posterior teeth due to their poor aesthetics.
- Special materials: usually belong to new materials, such as specially formulated ceramics, specially formulated lithium disilicate, etc. The clinical tracking time of these materials is still short, and the supporting data and evidence of stability and durability are not like the first three materials. It is so complete that it is not yet possible to definitively recommend it.
Summarizing the above information, the material selection for dental implants is rough as follows:
- The main implant material placed in the alveolar bone is titanium
- The main materials of the abutment placed under the gums are zirconia and titanium.
- The main crown materials placed on the gums are zirconia, titanium alloys, lithium disilicate, and other metals
