[Solution] The fossa-type three-dimensional omnidirectional jaw position frame device uses two mandibular ramus synchronization devices to synchronize the two mandibular ramus, and also synchronizes three-dimensional operation by interlocking the incisal rods in the corresponding condylar fossa and incisal fossa, thereby realizing the operating state of the mandibular dentition in the alternating cusp range.

Description

[Technical Field]

[0001] The present invention relates to the technical field of complete denture restoration, and more particularly to a jaw position frame device for transferring the occlusal relationship in the oral cavity and simulating the movement trajectory in all directions in the alternating range of the cusps. [Background technology]

[0002] During the complete denture restoration process, the occlusal relationship within the oral cavity must be transferred to a jaw positioning frame device to align the dentures, and static and dynamic jaw balance adjustments must also be performed. Denture alignment and static jaw balance adjustments must reflect the intermediate jaw position, and a conventional jaw positioning frame can easily achieve this function. However, dynamic jaw balance adjustments must reflect the three-dimensional space in which the entire oral dentition in the alternating cusp range and the mandibular dentition on the jaw plane in the direction of insertion and removal of the maxillary dentition undergo omnidirectional sliding. Currently, conventional jaw positioning frame devices using current technology have difficulty effectively simulating this three-dimensional space in a continuous and omnidirectional manner, which greatly limits the accuracy of jaw adjustment for complete dentures. Patients experience various discomforts during the initial stage of dentures insertion and cannot meet all functional requirements. Summary of the Invention [Problem to be solved by the invention]

[0003] In view of the above, the present invention aims to propose a fossa-type three-dimensional omnidirectional jaw position frame device to effectively solve the problems existing in the background art. [Means for solving the problem]

[0004] When the mandibular dentition is in the intermediate contact position, the bony condyle rests on the apex of the condylar cavity. As the jaw settles into position, as the muscles relax, the bony condyle leaves the triangular region where the apex of the condylar cavity rests, forming a three-dimensional space filled with fascia, ligaments, articular discs, and synovial fluid, as well as controlled by the masticatory system. At this time, the mandibular dentition enters the maxillary dentition in the insertion / removal direction from a different direction and then slides along the jaw surface in the insertion / removal direction to the intermediate contact position, completing the minute opening masticatory cycle. As a result, the mandibular dentition is reflected on the jaw surface in a three-dimensional movement that closely resembles translation. Due to the synchronous movement of the mandibular body and ramus, this movement is reflected in the left and right bony condyles, which also exhibit a three-dimensional movement that closely resembles translation. Following the minute opening, the mandibular dentition is guided along the condylar path, leaving the alternating cusp range, and subsequent movement becomes ineffective for jaw adjustment.

[0005] Therefore, this invention better reflects the movement state of the complete denture in the alternating cusp range and the mandibular dentition on the jaw surface in the insertion / removal direction of the maxillary dentition in the jaw position frame, thereby making precise omnidirectional adjustments to the complete denture, and also blurring the movement trajectory of the temporomandibular joint in the alternating cusp range to take into account the biological characteristics of the temporomandibular joint. This invention standardizes and expands the insertion / removal direction of the complete denture according to the movement state of the jaw dentition, thereby providing comfort and stability in the operation of the complete denture. The preferred embodiment is as follows:

[0006] The fossa-type three-dimensional omnidirectional jaw position frame device comprises a mandibular body base 1, a mandibular ramus assembly 2, and a maxillary body base 3. The mandibular ramus assembly 2 is located in the center and serves as a bridge connecting the upper and lower mandibular body bases. The upper end of the mandibular ramus assembly 2 is lockably and movably connected to the mandibular body base 1. The lower end of the mandibular ramus assembly 2 is lockably and movably connected to the maxillary body base 3. When the mandibular ramus assembly 2 is locked to the maxillary body base 3, the mandibular body base 1 is unlocked, and the device enters the denture arrangement mode. When the mandibular body base 1 is locked to the mandibular ramus assembly 2, the mandibular ramus assembly 2 is unlocked to the maxillary body base 3, and the device enters the fossa-type three-dimensional omnidirectional jaw position adjustment mode.

[0007] The essence of this invention is to synchronize the two mandibular ramus using two mandibular ramus synchronization devices, and to synchronize three-dimensional operation by interlocking the incisal rods in the corresponding condylar fossa and incisal fossa, thereby realizing the operating state of the mandibular dentition in the alternating range of cusps, and in addition, to achieve mutual conversion between denture arrangement mode and jaw position adjustment mode using lock conversion between the mandibular body base 1, mandibular ramus assembly 2 and maxillary body base 3. [Effects of the Invention]

[0008] The present invention has the following beneficial effects compared to the current technology:

[0009] 1) This device simulates the original operating state of the jaw dentition in the alternating range of cusps, and has better practicality than the conventional jaw position frame device used to simulate the movement of the temporomandibular joint. 2) The operating state of the jaw dentition simulated by this device is continuous and complete, and it ensures precise jaw position adjustment for complete dentures. 3) This device helps adjust and cut the working condition of complete dentures and maintain the denture base mechanically and biologically, providing better comfort and stability for complete dentures.
