When in use, the bridge body made of BioHPP material is installed on the implant by bolts, and then the crowns of different sizes are adhered to the connecting strips with thickness gradually decreasing from both ends to the center, so as to complete the installation of the bridge denture. The use of BioHPP material can not only greatly reduce the weight of the bridge denture, but also reduce the wear on the patient's gums, reduce the patient's allergic reaction, and improve the patient's wearing comfort. In addition, the thickness of the connecting strip is gradually reduced, which can not only better adapt to the distribution of natural teeth, so that each crown can have enough thickness to ensure the firmness of the crown, but also increase the weight of the bridge body in the entire bridge denture, so as to better reduce the weight of the entire bridge denture and ensure the comfort of the patient after wearing;

[0025] 2. Use zirconium oxide patches to isolate the bridge frame from the gums to avoid direct contact between the gums and the bridge frame. Zirconium oxide has better biocompatibility, which greatly reduces the probability of redness, swelling and inflammation of the patient's gums. In addition, zirconium oxide is not easy to stain, and it is more beautiful and non-staining in daily wear, so it is easy to clean and maintain oral hygiene.

[0026] 3. Fit the zirconia veneer tightly to the crown and maintain a smooth transition to improve the smoothness of the surface of the bridge denture and reduce the pressure on the end of the zirconia veneer or the end of the crown, thereby improving the firmness of the fixation between the zirconia veneer and the crown.
