2. Compared with traditional dental metal materials, titanium has excellent physical and chemical properties, good biocompatibility, small specific gravity and corrosion resistance. Titanium artificial bone, artificial joint, cardiac pacemaker and artificial root have been widely used in clinic, It also has the following advantages: light weight: titanium has a small specific gravity, which is 1 / 4 of that of gold alloy and 1 / 2 of that of cobalt chromium alloy. Therefore, the weight of denture made of pure titanium will be much lighter, which can rece the burden of the remaining tissues in the mouth, and has good comfort. Moderate hardness: it is between enamel and dentin, so the crown made of pure titanium, Low thermal conctivity: the crown made of pure titanium can better isolate the hot and cold stimulation, which is concive to the protection of dental pulp, No taste interference: titanium has good stability, no metal taste in the mouth, no taste interference. Transmissible X-ray: titanium has semi transmissibility to X-ray, wearing crown made of pure titanium can check whether there is caries inside the crown when X-ray, so as to achieve early detection and treatment, Good magnetic resonance compatibility: titanium is a non paramagnetic metal. Compared with the commonly used cobalt chromium alloy and nickel chromium alloy, the artifacts proced ring magnetic resonance examination are very small, and the impact on magnetic resonance examination is very small. In most cases, it is unnecessary to take out pure titanium denture ring head magnetic resonance examination

3. Hello, it's my honor to answer this question for you. Implant denture is a kind of restoration method after tooth loss. Not only the patients feel beautiful and comfortable, but also the masticatory effect of implant denture is much better than that of traditional removable denture. I hope my answer will help you.

4. Hao Ningning, director of Shijiazhuang sanbo plant, introced: in addition to excellent tissue affinity, the denture made of pure titanium has the following advantages:

5. In my opinion, if it is free missing, abutment condition is acceptable, bilateral 4 upper RPI cards, 3 upper lingual buttresses, and 4 mesial occlusal buttresses, the fulcrum line is the connecting line between the two combined buttresses. If the abutment teeth are not good, the alveolar ridge condition of the dental plate is good, and the occlusal force is not big. Consider the mucosal support type, with 4 upper arms clamped on both sides, and do not release the right to close the support. If there are eight cases, they are unilateral free end, RPI of free end and two three arm cards on the other side.

6. Pure titanium can be used to make crowns, bridges and removable dentures. Compared with traditional dental metal materials, titanium has excellent physical and chemical properties, good biocompatibility, small specific gravity and corrosion resistance. Titanium artificial bone, artificial joint, cardiac pacemaker and artificial root have been widely used in clinic. In addition to excellent tissue affinity, the denture made of pure titanium also has the following advantages: light weight: the proportion of titanium is small, which is 1 / 4 of that of gold alloy and 1 / 2 of that of cobalt chromium alloy. Therefore, the denture made of pure titanium will be much lighter, which can rece the burden of remaining tissue in the mouth, and has better comfort. Moderate hardness: between enamel and dentin, so the crown made of pure titanium will not wear the natural teeth too much. The post made of pure titanium can make the stress transmission in the root more in line with the physiological model, and rece the risk of root fracture. Low thermal conctivity: the crown made of pure titanium can better isolate cold and hot stimulation, help protect dental pulp, and avoid pain when eating too cold or too hot food. No taste interference: titanium has good stability, no metal taste in the mouth, no taste interference. Transmissible X-ray: titanium has semi transmissibility to X-ray. When wearing a crown made of pure titanium, it can check whether there is caries inside the crown when taking X-ray, so as to achieve early detection and early treatment. This is an advantage that other metal materials used for making denture do not have. Good magnetic resonance compatibility: titanium is a non paramagnetic metal. Compared with the commonly used cobalt chromium alloy and nickel chromium alloy, the artifacts proced ring magnetic resonance examination are very small, and the influence on magnetic resonance examination is very small. In most cases, it is not necessary to take out the pure titanium denture ring the head MRI examination.

7. The formal beauty of denture restoration modeling is displayed from multiple directions and angles. The so-called formal beauty refers to the regular combination of various formal factors (such as line, shape, color, etc.) of the object, which forms the common characteristics of the beauty in form and proces a series of rules of formal beauty, such as repetition, uniformity, symmetry, balance, coordination, rhythm, proportion, harmony, etc. A perfect complete denture not only adapts to the principles of anatomy and biomechanics, but also has various forms of beauty. The whole process of complete denture restoration is based on the law of beauty. 1. Symmetry and balance the structure of the human body, especially the oral and maxillofacial region, reflects this beauty. The complete denture is more prominent. Based on the median sagittal plane, it is not only symmetrical and balanced in size, shape and color, but also symmetrical in three-dimensional space. In a word, symmetrical beauty in the geometric figure of point, line, surface and angle of complete denture gives people a kind of aesthetic feeling and balance, which is the aesthetic significance of complete denture to set off the center, stability and solemnity. 2. Repetition and uniformity are the same form, which can also be called neat beauty. The complete denture artificial teeth are arranged as a whole, no matter from the labial buccal side, lingual side, occlusal surface, the teeth are arranged regularly, which makes people feel orderly and orderly. The functional and morphological unity of incisors, canines, bicuspines and molars makes the unity and change combine, further enhancing the aesthetic feeling. 3. Proportion and harmony the size of the central incisor of complete denture keeps a certain proportional relationship with many facial organs. The mesial and distal median diameter of the upper central incisor is 1 / 16 of the face step width, which is 1.5 times of the width of the lower central incisor, and the width of the upper central incisor is 1 / 6.5 of the pupil spacing. These data can be used as a reference for the selection of artificial teeth. The length width ratio of anterior teeth is close to "golden section", that is, 1:0.618.4. Harmony and contrast are opposite in the middle of difference, while contrast is opposite in the middle of difference. The color of complete denture obviously presents the formal beauty of harmony and contrast. The gingival end of incisor is yellow, the incisor is white, and graally moves. There is no obvious boundary, and the lip surface is glossy and lifelike. Add appropriate amount of dark red fiber into the base material, imitate the vascular network in the gum, and make the color more harmonious and beautiful. 4. Level and rhythm it is generally believed that only dynamic things have rhythm, but this is not the case. It is true of the thick and light levels in painting, the rows of mountains in architecture, and the layers and obstacles in natural landscape. The arrangement of artificial teeth in complete denture is unlating, the cusps and pits on the occlusal surface alternate, and the cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae cristae. Details of complete denture restoration: after all teeth are missing, complete denture restoration can restore most of the masticatory function, improve pronunciation and face, and relieve various psychological pressure caused by missing teeth. From the first impression to the first denture, we usually need to see a doctor four times. Complete denture restoration is: take impression - determine occlusal relationship - test teeth - wear teeth. After the complete denture is put in, because the soft and uneven mucosa (commonly known as the gums) is sandwiched between the hard denture and the alveolar bone, the thin part of the mucosa is more prone to tenderness. If there is pain or other discomfort, it needs to be adjusted by a doctor. In particular, we should remind you that it's better to insist on wearing dentures on the day before the return visit, so that doctors can quickly and accurately diagnose and deal with the painful parts by using the denture's impression on the gums. In addition, the stability of complete denture is not as good as that of clasp denture, especially mandibular denture, which is easy to loose and fall off when speaking and eating. After excluding the reasons of the denture itself, we still need to practice under the guidance of doctors and graally adapt. The adaptation period varies from person to person and generally takes 1-3 months.

8. The advantages of removable denture are as follows: 1; 2. Less tooth tissue was removed; 3. Patients can take off and wear by themselves; 4. The proction is simple and the cost is relatively low; 5. Easy to repair.

10. Whether the porcelain teeth are better or the implant teeth are better needs to be judged and selected by the prosthetic doctors according to the specific situation. Generally speaking, porcelain fused to metal (PFM) teeth should be fixed. The teeth on both sides of the defect should be adjusted and ground to make PFM crowns. A PFM crown should be made between the two PFM crowns to repair the defect teeth, which will damage the adjacent teeth on both sides. However, if the adjacent teeth have decayed and need to be restored with full crown, fixed bridge repair is more reasonable. If the adjacent teeth on both sides of the gap are normal and good teeth, the porcelain fused to metal teeth will be damaged greatly. At this time, dental implant is the most ideal restoration scheme.
