Description

Technical Field

[0001] This application belongs to the field of dental restoration technology, specifically relating to a high-strength bar-type Maro Bridge dental restoration structure. Background Technology

[0002] In existing technologies, clasp-type Maro bridges are widely used in dental restorations, effectively restoring chewing function and providing convenience for patients. However, currently available clasp-type Maro bridges have some shortcomings in terms of materials and structure.

[0003] In current technology, conventional bar-and-clasp Malo bridge restorations typically employ a composite structure combining a pure titanium bar-and-clasp framework as the inner crown support with a zirconia all-ceramic outer crown. While pure titanium possesses sufficient strength and good biocompatibility, meeting the material performance requirements of dental restorations to a certain extent, it suffers from significant shortcomings in aesthetics. When pure titanium frameworks are combined with zirconia crowns, metallic translucency or blackening is prone to occur, resulting in a dull overall color of the crown and bridge, failing to fully mimic the color of natural teeth. This is a significant drawback in the field of dental restorations, where aesthetics are paramount, potentially affecting the patient's smile and causing psychological distress.

[0004] Furthermore, while using other non-metallic materials for the clasp-type Maro bridge may improve aesthetics, it may also present challenges due to insufficient strength. For instance, some dental restorations made of resin, although similar in color to teeth, are prone to breakage, deformation, or wear under long-term biting forces, affecting their lifespan and stability and failing to meet patients' needs for high-performance and long-lasting restorations.

[0005] Therefore, improvements are urgently needed to comprehensively enhance the mechanical properties, biocompatibility, and aesthetics of the clasp-type Maro bridge, so as to better meet the clinical needs of dental restoration, improve the patient experience, and enhance the restorative effect. Utility Model Content

[0006] This application aims to address the technical problems in existing technologies, such as the fact that traditional bar-and-clasp Malo bridges are usually made of metal, which oxidizes and turns black over time, failing to fully mimic the color of natural teeth and severely reducing aesthetics; and that resin-based bar-and-clasp supports have low strength, short lifespan, and poor user experience. The application proposes a high-strength bar-and-clasp Malo bridge dental restoration structure.

[0007] This application adopts the following solution: a high-strength bar-type Malo Bridge dental restoration structure, comprising multiple bases disposed on the patient's jawbone, multiple support cylinders disposed on the bases, a first connecting assembly disposed between the bases and the support cylinders, a support bar holder disposed on the support cylinders, a second connecting assembly disposed between the support bar holder and the support cylinders, a crown disposed on the support bar holder, and a third connecting assembly disposed between the crown and the support bar holder, wherein the support bar holder is made of zirconium oxide.

[0008] In some feasible embodiments, the support cylinder includes an upper cylinder, a lower cylinder disposed on the upper cylinder, and a first fastening hole disposed on the upper cylinder, wherein the cross-sectional diameter of the upper cylinder is larger than the cross-sectional diameter of the lower cylinder.

[0009] In some feasible embodiments, the first connecting component includes a first connecting groove on the base and a first fastening groove on the bottom of the first connecting groove. The lower cylinder extends into the first connecting groove so that the support cylinder is detachably mounted on the base. When the lower cylinder extends into the first fastening hole, the bottom of the upper cylinder abuts against the top of the base, and the first fastening hole communicates with the first fastening groove.

[0010] In some feasible embodiments, the second connecting component includes a second connecting groove provided on the support rod clip, and a second fastening hole provided at the bottom of the second connecting groove. When the upper cylinder body is inserted into the second connecting groove, the first fastening hole communicates with the second fastening hole.

[0011] In some feasible embodiments, the third connecting component includes a third connecting groove on the crown near the support bar, and a plurality of third fastening holes at the bottom of the third connecting groove. When the support bar is inserted into the third connecting groove, the third fastening hole, the second fastening hole, and the first fastening hole are interconnected.

[0012] In some feasible embodiments, the support cylinder is made of titanium alloy.

[0013] In some feasible embodiments, the support rod clip includes a plurality of arc-shaped expansion portions and a linear contraction portion disposed between two adjacent arc-shaped expansion portions, and the second connecting groove is matched and disposed on the arc-shaped expansion portions.

[0014] In some feasible embodiments, the support rod clip also includes a decorative layer attached to the outer surface of the support rod clip.

[0015] In some feasible embodiments, a fastener is also included, which is simultaneously fitted through the first fastening groove, the first fastening hole, the second fastening hole, and the third fastening hole, and the fastener is made of titanium alloy.

[0016] Compared with the prior art, this application has the following beneficial effects:

[0017] This application provides a high-strength clasp-type Malo Bridge dental restoration structure, comprising multiple bases disposed on the patient's jawbone, multiple support cylinders disposed on the bases, a first connecting component disposed between the bases and the support cylinders, a support clasp disposed on the support cylinders, a second connecting component disposed between the support clasp and the support cylinders, a crown disposed on the support clasp, and a third connecting component disposed between the crown and the support clasp. The support clasp is made of zirconia. The use of zirconia in the support clasp effectively avoids oxidation of the support clasp surface, resulting in a dark crown color and poor aesthetics after bonding with the zirconia crown. It better simulates the color of natural teeth, improving aesthetics. Simultaneously, its high strength extends its service life, enhances the stability of the dental restoration structure, and ensures that it is not easily loosened or dislodged during patient use. This effectively improves the user experience and has the advantages of reasonable structure, excellent performance, long service life, good user experience, and ease of promotion and implementation.
