Description
Technical Field
The invention relates to the technical field of orthodontics, in particular to a polishing method for 3D printed teeth.
Background
Three-dimensional printing (3D printing), which is a technique for realizing the physical structure of an object by layer-by-layer printing using materials such as powdered, linear, or block plastics, wax, or metal based on a digital model file (typically an STL or CAD file), is also called additive manufacturing, and covers various different types of techniques, such as fused deposition, laser sintering, photo-curing, binder jetting, and the like.
In recent years, dental restoration based on software design is rapidly popularized, 3D printing equipment is introduced into many dental clinics and professional denture production enterprises, 3D design models are directly converted into practical products by combining 3D printing digital oral technology, and high-precision and low-cost oral data and products are brought to the dental industry. Compared with the traditional manufacturing mode, the oral cavity 3D printing is more suitable for manufacturing products with small-batch customization and complex shapes, the existing 3D printing is applied to the fields of false tooth printing, appliance manufacturing, preview operation model manufacturing, operation guide plate manufacturing and the like of oral cavity medical treatment, and the accuracy and the efficiency of the oral cavity medical treatment are greatly improved.
At present, when a 3D printing device is used for printing teeth by some dental clinics or professional denture production enterprises, the surface or one side of the printed teeth is rough and opaque, the attractiveness is poor, and observation research, teaching demonstration or treatment previewing is not facilitated.
To this end, we propose a polishing method of 3D printed teeth to solve the above problems.

s2, evaluating the roughness of the printed teeth;
s3, roughly polishing and flattening the surface of the printed tooth by using related equipment, and weakening the striation structure;
s4, carrying out progressive polishing on the roughly polished and leveled printed teeth;
s5, cleaning the surface of the printed tooth after progressive polishing;
s6, carrying out surface curing treatment on the cleaned printed tooth;
and S7, cleaning and rubbing the printed teeth after the curing treatment is finished.
Preferably, the evaluation criterion is one-sided rough opacity or full rough opacity.
Preferably, the rough polishing and flattening of the printed teeth is performed by using loose wind OneGloss.
Preferably, in the step S4, when the printed teeth are progressively polished, two kinds of polishing wheels for teeth are used for progressively polishing, respectively.
Preferably, the surface curing treatment of the cleaned printed tooth in S6 includes the following steps:
s61, fixing the printed teeth by using a table type support, and uniformly coating a thin layer of liquid brightener (BisCoverLV);
s62, carrying out primary photocuring 5S treatment on the printed tooth after being treated in the S61 in each direction;
and S63, coating and coating an oxygen inhibitor on the surface of the printed tooth after the photo-curing 5S treatment, and fully curing.
Preferably, in S7, the printing teeth after being cured are cleaned and rubbed with a flannel wheel during surface cleaning and rubbing treatment.
