Description
Technical Field
The invention relates to digital information of space positions and postures of teeth, in particular to a bionic reconstruction method of space poses of teeth in an occlusion function state.
Background
The occlusal force exerts pressure on the teeth, which causes deformation of periodontal ligament and alveolar bone of non-rigid structure, resulting in displacement of teeth. Research shows that under the horizontal force of 5N, the displacement of the teeth of the normal incisors reaches 120 mu m, the molar is 40-80 mu m, and large individual difference exists. In the last hundred years, the influence of the factor on the precision of the space position and posture information of the teeth recorded by the impression is not considered when the dentition impression is clinically prepared in the oral cavity, so that the prosthesis prepared based on the impression cannot be completely suitable for the occlusion function of a patient, and a large amount of adjustment and grinding are required clinically.
Disclosure of Invention
The invention aims to provide a bionic reconstruction method of a tooth space pose in an occlusion function state, which can further improve the precision of acquiring all tooth space positions and postures in an individual occlusion function state on the basis of the existing oral three-dimensional scanning technology, and further improve the precision of an oral diagnosis and treatment design scheme based on the data.
In order to achieve the purpose, the invention has the following technical scheme:
the invention relates to a bionic reconstruction method of a tooth space pose in an occlusion function state, which comprises the following steps:
1) respectively scanning the maxillary dentition and the mandibular dentition of a patient by using an intraoral three-dimensional scanner to obtain three-dimensional data J1 and J2;
2) scanning the whole dentition of the patient with the upper and lower jaw teeth after being occluded with normal force by using an intraoral three-dimensional scanner to obtain three-dimensional data J0;
3) extracting three-dimensional data of each tooth crown in J1 and J2 in software;
4) registering the extracted crown data of each tooth to J0; the bionic position and the bionic posture of the space pose of the teeth under the individual occlusion function state can be realized.
And 4) acquiring digitalized accurate data of the spatial positions and postures of all teeth in the individual bite function state.
The invention has the advantages that: the invention can further improve the precision of obtaining the spatial positions and postures of all teeth under the individual occlusion function state on the basis of the existing oral cavity three-dimensional scanning technology, and further improve the precision of oral cavity diagnosis and treatment design schemes based on the data.
Detailed Description
The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The invention relates to a bionic reconstruction method of a tooth space pose in an occlusion function state, which comprises the following steps:
1) respectively scanning the maxillary dentition and the mandibular dentition of a patient by using an intraoral three-dimensional scanner to obtain three-dimensional data J1 and J2;
2) scanning the whole dentition of the patient with the upper and lower jaw teeth after being occluded with normal force by using an intraoral three-dimensional scanner to obtain three-dimensional data J0;
3) extracting three-dimensional data of each tooth crown in J1 and J2 in software;
4) registering the extracted crown data of each tooth to J0; the bionic position and the bionic posture of the space pose of the teeth under the individual occlusion function state can be realized.
And 4) acquiring the digitalized accurate data of the spatial positions and postures of all teeth in the individual occlusion function state.
Normal force occlusion of upper and lower jaw teeth of a patient: in normal chewing movement, the maximum biting force is not needed, the chewing muscle only exerts partial force, the force for chewing food is only half of the force which can be supported by the periodontal tissues, and the other half of the supporting capability is stored in the periodontal tissues, so that the fixed bridge repair utilizes the characteristic. The royal conceptive teacher in 1963 uses an occlusal dynamometer to test the chewing force of normal and healthy people, the average value is 22.4-68.3kg, the chewing force in daily life is only 10-23kg, and only about half of the periodontal potential is used. And in the process of preparing occlusion records in the oral clinic (including recording virtual occlusion records by using an intraoral three-dimensional scanner) and adjusting the occlusion in the prosthesis clinic, the patient is ordered to occlude the cusp malposition with normal occlusal force, the occlusion high point is detected, and the occlusion adjustment is guided.
Software: geomagic Studio software (Geomagic, USA) is reverse engineered, but not limited to this software.
As described above, the present invention can be more fully realized. The above description is only a reasonable embodiment of the present invention, and the scope of the present invention includes but is not limited to the above description, and any insubstantial modifications of the technical solution of the present invention by those skilled in the art are included in the scope of the present invention.
