A: VinciSmile aligner applies the original imported orthodontic special medical thermoplastic polymer materials, which is with European CE certification, non-toxic and harmless.
A: Compared with the traditional orthodontic treatment, invisible aligner is more suitable for patients with periodontal disease, of course, it is necessary to ensure the stability of the periodontal condition in the early stage.
A: VinciSmile invisible orthodontic appliance can be applied to orthodontic treatment in adolescents with permanent dentistry, preferably the patients whose second molar has erupted to construct the skeletal relations. In addition, under this circumstance, users are required to perform great compliance.
A: Generally speaking, patients need to wear a retainer all the day (remove it when eating and brushing teeth) within half a year after the treatment. Further, the retainer can be worn only at night half a year later. Patients with periodontal disease are recommended to wear a retainer for life.
A: Definitely yes, the arch is expanded by the VinciSmile invisible orthodontic appliance itself, and it performs quite well.
A: It depends on the malocclusion degree of the patients. Generally, it takes about 1-2 years.
A: The 3D orthodontic scheme can be designed within 3 work days since we have received the completed case information.
A: The aligners will be fabricated and shipped out within 4 workdays after the 3D scheme is approved.
A: Please submit the completion information (die stone model, patient’s photos, X-ray photos and confirmation form) in a timely manner.
A: It is recommended that the attachments can be bonded separately or the attachment template can be cut into several segments for aims of easy bonding.
A: It is recommended that the conventional acid etch and dental resin can be applied, and the self-etching primer system, flowable resin and orthodontic adhesive are forbidden. Furthermore, only a thin layer of the bonding material can ensure the great results, and excessive material will result in poor bonding strength.
A: 1. initial position
· Whether the occlusion and middle line position is coincident with the actual situations?
·Whether the IPR amount is as expected?
· Have we designed any IPR to wrong teeth?
· Have we designed the IPR at the right time?
· Is each tooth displacement appropriate to keep periodontal health?
· Whether all the movement are set reasonably (mainly anchorage control)?
· Are all the attachments designed reasonably?
· Have we designed any attachment to wrong teeth?
4. Final Position
· Is the teeth alignment and midline adjustment as expected?
· Is overjet/overbite within normal range?
· Is the curve of Spee and levelling result as expected?
· Is the arch form symmetric?
· Are the gaps fully closed? Or whether the reserved space meets the requirements?
· Whether the occlusal relationship of molars and canines is as expected?
· Is the intercuspation of the posterior teeth desirable?
A: The Rotate and Delete options will show up on the screen when you put the mouse cursor on the edit photo, doctors can click them if needed.
A: Click the uploaded photo and choose a new one to replace it.
A: You can click [Improve] to modify what you input before submission, but if you want to change something after submission, you'll have to contact your sales manager to return the case first.
A: There are no more than 3 missing teeth.
A: The number of restorations made on a piece of block is related to the size of the restoration and the ability of typesetting. Unsure how many can be made, usually about 15.
A: (1) There is a problem with the sintering process or the sintering furnace. Insufficient crystallization time will cause problems such as under-cooking and whitening of zirconia (the main crystallization temperature is between 1000-1450, the heating speed is slow, and at least 120 minutes of heat preservation is required). If the sintering temperature is too high, the dyeing effect will become lighter. First confirm whether the sintering program used by the customer is the standard sintering curve provided by us, and then confirm whether the customer’s sintering furnace has problems such as unstable temperature field or uncleaned for a long time. If necessary, check the temperature field, or suggest that the customer replace the sintering furnace for sintering. （2）The teeth are not dried during the dyeing process, resulting in uneven local staining, and the residual water in the teeth may cause a large difference in local temperature of the teeth, resulting in insufficient local crystallization or cracks.
A: (1) Due to the abnormality of the bur or engraving machine, cracks in the restoration were not found during the cutting process or re-grinding process, resulting in fracture after sintering. (2) Not dried after dyeing, resulting in uneven local temperature during the sintering process, cracks or breaks (3) There is a problem with the sintering process, the heating speed is too fast or the cooling speed is too fast, causing cracks or fractures.
A: The customer's tool has been used for too long, the customer's engraving machine has been uncalibrated for a long time, or the spindle has been deviated, and the restoration design has problems.
A: Yes. Since the sintering machine used by individual customers cannot complete the 6-step sintering setting, we can modify it to 4 steps according to the guidance of the project department. But it is necessary to control the sintering temperature and time
A: Yes, please use PMMA special engraving bur.
A: Polymethylmethacrylate (PMMA) is traditionally the most common and oldest material used to make complete dentures because of its excellent dimensional stability in the oral environment, low cost, light weight, aesthetics and aesthetics Etc. Easy to manufacture and repair. It has excellent permeability and aesthetics, and integrates into the oral cavity without discomfort. However, there are a number of problems with the use of PMMA, including denture breakage caused by water absorption and impact, and reductions in flexural strength, porosity, and polymerization shrinkage. In addition, PMMA for dental materials contains pigments that mimic oral tissue and additives such as nylon or acrylic synthetic fibers in the transparent powder component; the liquid component, in addition to the main component, methyl methacrylate (MMA) monomer, also Contains cross-linkers and inhibitors. Inhomogeneity of the two components when mixed can lead to reduced material strength and bacterial intrusion, thereby reducing biocompatibility. In order to overcome the shortcomings of PMMA such as insufficient mechanical properties and bacterial invasion, the material composition was changed and various reinforcing materials were added.
A: Monolayer PMMA has only one color from top to bottom and does not have a natural gradient like natural teeth. Nobilcam's Multilayer PMMA is different from other products in that it has been approved by the FDA for intraoral use as a long-term temporary product with many layers of varying color and translucency from the cervical margin to the incisal margin. Numerous layers help create natural-looking restorations that, when ground to full contour, closely mimic natural dentition. After milling, the lab technician simply needs to polish or (light cure) the enamel to obtain the appearance of the important tooth.
A: (1) High quality raw material make sure the stable quality of product. (2) X-Ray inspection Guarantee no bubbles inside the disc. (3) Strong R & D ability make sure the Good compactness & Biocompatibility.
A: The commend dental software are recommended. For example, 3shape, Exocad.
A: The commend milling machine is good enough. But we recommend using 5-aix milling machine with wet milling model which will be better. Recommend Spindle Speed: 21000RPM.
A: (1) Eliminates the wax-up stage, investing, casting and finishing. (2) Biocompatible, light weight, durable, and precise. (3) Flexible and transparent clasps are virtually unbreakable, avoiding the need of metal
