Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a technical solution: a process for biologically and intelligently carving ceramic teeth comprises the following steps: step 1, preparing a silicon rubber or alginate material, and making an impression of a patient's mouth by biting the impression of a tooth; step 2, the staff obtains the oral data of the patient by scanning the oral impression of the patient; step 3, using professional software to carry out CAD design and CAM typesetting; 4, transmitting the data to a tooth carving machine; step 5, setting engraving wall thickness data; step 6, loading a dental disc new material; step 7, full-automatic carving of the dental crown is carried out at normal temperature; step 8, cleaning and carving the prepared dental crown; step 9, applying porcelain; step 10, porcelain baking; and 11, glazing.
As shown in fig. 2, the new dental disc material (1) is a medical cobalt-chromium ceramic alloy or a medical zirconia ceramic material which has high strength, hardness, no high-temperature metal oxide on the inner wall, no volatilization and oxidation of trace elements, no temperature difference and no internal stress; the dental crown is manufactured by carving the dental crowns (2), (3), (4) and (5) at normal temperature, and the inner wall of the dental crown does not contain high-temperature metal oxide; the dental crowns (2), (3), (4) and (5) do not need to be manufactured at high temperature; compared with the traditional cast dental crown and the 3D printed dental crown, the alloy has no volatilization and oxidation of trace elements; the dental crowns (2), (3), (4) and (5) are carved at normal temperature, and have the following effects: compared with the traditional cast dental crown and the 3D printed dental crown, the processing process has no temperature difference and does not generate internal stress.
The engraving wall thickness of the crown bridge (3) is set to be 0.4mm when the long bridge (2), the crown bridge (3), the free end bridge (4) and the dental implant (5) are engraved, and the other thickness is set to be 0.6 mm
Example 1
The long bridge is formed by cutting and processing the zirconia ceramic block for the all-ceramic denture and then sintering the zirconia ceramic block at high temperature, so that the long bridge is seriously deformed, can not be in place clinically, and can not be repaired or used.
As shown in figure 3, the process for engraving the porcelain teeth by adopting the biological intelligence of the invention uses a full-automatic 5-shaft linkage tooth engraving machine to engrave 12 continuous half-mouth teeth (commonly called long bridges) obtained by a new medical zirconia ceramic disc material, has no deformation and high precision, is closely attached to the ground abutment teeth of a patient in the oral cavity, and is fixed in place.
Example 2
12 continuous half-mouth teeth (commonly called long bridges) formed by high-temperature melting and casting of traditional granular ceramic alloy or 12 continuous half-mouth teeth (commonly called long bridges) formed by 3D laser printing (digital additive manufacturing method) are sintered at high temperature, and the manufactured long bridges are seriously deformed and cannot be in place clinically.
As shown in fig. 4, 5, 6, and 7, the conventional method is to cut the long bridge into several segments, place the segments on the dental cast, electrically weld the segments, and then weld the segments, which increases the weight of the teeth and causes poor independence between individual teeth and poor appearance; on the other hand, the welding position can crack, break and fracture the porcelain.
As shown in figure 8, the process for engraving the porcelain teeth by adopting the biological intelligence of the invention uses a full-automatic 5-shaft linkage tooth engraving machine to engrave 12 continuous half-mouth teeth (commonly called long bridges) obtained by the new medical cobalt-chromium porcelain alloy disc material, has no deformation and high precision, is closely attached to the ground abutment teeth of the patient in the oral cavity, and is fixed in place.
Example 3
The crown bridge is formed by cutting and processing a zirconia ceramic block for the full-ceramic denture and then sintering the zirconia ceramic block at high temperature, although the designed thickness of the size of the dental crown reaches 1.0mm to 1.5mm, the good teeth (abutment) of a patient are ground when the patient prepares the teeth, but the strength of the posterior teeth is not enough, so that the fracture of the patient within half a year is caused.
As shown in fig. 9, continuous 3 teeth (commonly called crown bridges) with short back teeth, which are formed by high-temperature melting and casting of traditional granular ceramic alloy, or continuous 3 teeth (commonly called crown bridges) with short back teeth, which are printed by 3D laser (digital additive manufacturing method), are formed by high-temperature sintering, which also causes the manufactured crown bridge to be deformed and warped all the time, and the correct positioning of the crown bridge cannot be ensured.
As shown in figure 10, the process for engraving the porcelain teeth by adopting the biological intelligence of the invention uses a full-automatic 5-shaft linkage tooth engraving machine to engrave 3 continuous half-mouth teeth (crown bridges) obtained on a new material of a medical zirconia ceramic disc, has no deformation and high precision, is closely attached to the ground abutment of a patient in the oral cavity, and is fixed in place.
Example 4
As shown in fig. 11, the connecting body (commonly referred to as an abutment) connecting the implant and the tooth is made of titanium alloy, the abutment is cut by a 5-axis linkage engraving machine, and the fit precision of the tooth and the implant abutment manufactured by the invention is negative deviation fit (interference fit).
Example 5
As shown in fig. 12 and 13, the final 2 continuous 5 teeth (commonly called free end bridges) missing posterior teeth, which were manufactured using the zirconia ceramic block for the all-ceramic denture, were cut from the zirconia ceramic block for the all-ceramic denture and then sintered at high temperature, but the free end bridges and the abutment teeth had poor matching accuracy and large gaps, and thus the patient broke within one year of use.
The continuous 5 teeth (commonly called free end bridges) with the last 2 posterior teeth missing, which are formed by high-temperature melting and casting of traditional granular porcelain alloy, or the continuous 5 teeth (commonly called free end bridges) with the last 2 posterior teeth missing, which are printed by 3D laser (digital additive manufacturing method), lead to fracture of a patient within one year due to poor matching precision and large gap between the free end bridges and the abutment teeth.
As shown in figure 14, the free end bridge obtained by carving the novel material of the medical zirconia ceramic disc by using the full-automatic 5-shaft linkage tooth carving machine in the process of biologically and intelligently carving the porcelain tooth is not deformed, has high precision, is closely attached to the ground abutment of a patient in the oral cavity and is well fixed in place.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
