Polishing and polishing of complete dentures | Help patients restore a more natural and clean oral cavity

With the improvement of people's living standards and the acceleration of population aging, the oral health and quality of life of more than 20 million edentulous elderly people in China have received more and more attention. The loss of dentition seriously affects the quality of daily life, so the demand for complete dentures is also increasing year by year.

Complete dentures are mucosa-supported dentures made for patients with missing teeth. The complete denture is composed of the base and the artificial teeth. The denture base is closely fitted to the mucous membrane and retained by the adsorption force and atmospheric pressure generated by the edge sealing. It is adsorbed on the upper and lower alveolar ridges to restore the patient's defective tissue and face Appearance, recovery of chewing and pronunciation functions.

The tissue surface, polished surface, and occlusal surface make up the surface structure of a complete denture. The polished surface is the surface of the denture that contacts the soft tissues and muscles of the lips, cheeks, and lingual side. The polished surface should form an appropriate concave slope, so that the denture base can be attached to the alveolar ridge through the action of the labiobuccal tongue muscle, and the retention of the denture can be enhanced. The inward force of the lip and buccal muscles and the outward force of the tongue muscles should be in balance in order to maintain the level and stability of the denture.

The polished surface of the denture needs to be finely ground and polished to ensure that the surface of the complete denture is clean. After the production is completed, it needs to go through multiple steps such as ring opening, sandblasting, rough grinding, fine grinding, sandblasting, electrolysis, polishing, brightening, and adjustment before it can be put into the working model, and finally handed over to the dentist for clinical trial. In this process, the effect of grinding and polishing is very important. Grinding removes high points and trims the shape, which can smooth the uneven surface and make the shape of the restoration more natural. Polishing can remove scratches and original irregular surfaces left by grinding, make the surface of the restoration appear glossy, increase aesthetic comfort, improve the surface gloss of the restoration, reduce plaque accumulation, and prolong the life of the restoration. The polished and polished dentures have the highest finish, and are smoother and more comfortable to wear in the patient's mouth like a work of art. Metal bracket sanding can be enhanced with the application of high-quality materials.

Aiming at the most labor-intensive and material-wasting polishing process in denture processing, the automatic denture polishing machine is a polishing solution that eliminates manual labor and saves consumables. The automatic denture polishing machine is mainly composed of a motor, a casing, a rotating shaft, a rotating dragon, a transmission part, and a roller part. It can not only fully absorb abrasives and dentures, brackets and other products, but also ensure the polishing effect of denture edges, abutments, inner crowns, tissue contact surfaces, clasps, and narrow and thin parts. Fully automatic denture polishing machine is widely used in various denture metals and denture materials, such as mild steel, nickel-chromium alloy, cobalt-chromium alloy, titanium alloy, gold alloy, pure titanium and other stainless metals and denture thermosetting resin, self-curing resin, Fine polishing of materials such as elastic resin, photocurable resin, porcelain resin, tempered resin, etc.

Similar to the principle of planetary autobiography and revolution, the work of the automatic denture polishing machine is subject to bidirectional reverse rotation and centrifugal action, so that the grinding stone is adsorbed on the surface of the denture, causing the equipment to rotate at a uniform speed. In the process, the static shaft, clutch connecting wheel and main wheel are connected. It is integrated, and is slidingly matched with the main wheel. When working, the clutch is in the combined position, the main wheel is the fixed wheel, and the connecting wheel is the driving wheel. During the operation, due to the action of the intermediate wheel, the runner is driven to rotate, so that the grinding cylinder rotates in reverse, so that the polishing abrasives and polishing components in the grinding cylinder are fully contacted and ground, and finally the mirror polishing effect is achieved.
