Description

Technical Field

[0001] The present invention relates to the technical field of dentures, and in particular to a complete denture device equipped with an auxiliary retention structure. Background Art

[0002] Complete dentures are removable dentures designed for patients with complete edentulism in both the upper and lower jaws. They are primarily used to restore oral function and appearance. Traditional complete dentures typically consist of two components: artificial teeth and a denture base. Retention relies on the close fit between the denture base and the edentulous jaw mucosa (i.e., gums) and the suction force generated by the edge seal (similar to the negative pressure generated by cupping or suction cups), allowing the denture to adhere to the upper and lower alveolar ridges. This retention and occlusal pressure allow the denture to restore the patient's chewing, pronunciation, and appearance.

[0003] In clinical practice, when patients have low residual alveolar ridges, soft mucosa, or low saliva secretion, dentures struggle to maintain optimal adhesion, leading to loosening and dislocation during use, mucosal tenderness, and other issues, resulting in patients being unable to use the dentures and eat properly. This situation occurs in approximately 20% of complete denture treatments. To address this issue, the present invention proposes a complete denture device equipped with an auxiliary retention structure to address this problem. Summary of the Invention

[0066] Spread the soft lining material (powdered solid and liquid substances mixed in proportion to form a creamy mixture) evenly on the edge of the retention net and the base bracket; quickly place the base bracket in the correct position of the gums in the mouth and shape the edges; after about 5-10 minutes, the soft lining material solidifies and stabilizes, forming a stable state similar to rubber skin, achieving personalized fit between the base bracket and the gums.

[0067] Place the retention plate on the base bracket so that the retention hole is aligned with the screw channel; use the retention screw (2mm diameter, 10mm length) to screw into the screw channel to fix the retention plate on the base bracket; install the handle and insert the threaded rod at the top of the handle into the threaded groove at the bottom of the retention plate to facilitate the doctor's operation. After installation, remove the handle.

[0068] Put the loop of the top strap on the patient's head, and adjust the length of the first adjustment strap and the second adjustment strap to comfortably fix the top strap on the head; insert the insertion rod of the denture stabilizing rod into the connecting groove of the base bracket, and adjust the tension of the elastic band through the adjustment rod to ensure that the denture fits firmly on the gums.

[0069] Clean your dentures with a soft-bristled toothbrush and mild toothpaste after daily use; visit a professional dental clinic for a comprehensive inspection and maintenance every 6 months.

[0070] 4. Effects and Advantages

[0071] Through the combination of soft lining material and retention net, the base bracket can be personalized fitted to the patient's gums, improving wearing comfort and stability; the retention head frame provides additional fixing force through elastic rubber bands and denture stabilizing rods, effectively preventing the denture from loosening and falling off.
