Description
Technical field
The invention belongs to Clinical Science of Stomatology technical field, it is related in dentistry experimental teaching carrying out tooth to professional person
The model of body preparation training.
Background technique
In clinical oral work, uneven, cracked teeth of defect of teeth caused by dental caries etc., tooth staining, denture etc. is normal
The clinical problem seen.Need to do tissue of tooth specific grinding (i.e. tooth preparation) during the solution of these problems, then
It is repaired to achieve the purpose that treatment.Operation by human hand technical ability determines the disposing capacity of Dentist, therefore in dentistry
In the incubation of professional, experimental teaching is mostly important one of component part.
The tooth (Isolated Tooth) that traditional tooth preparation experimental teaching falls off or pulls out using people is trained, it is advantageous that
Feel when removing is consistent with clinical manipulation.But disadvantage is very prominent, including source is difficult, tooth position randomness is big, the abrasion of tooth body
And dental caries badly cause tooth body anatomical structure destroy or be not true to type, train it is not reproducible etc., and assessment mode can only using naked eyes see
It examines, assessment result is affected by the subjective idea of evaluator.In order to make up the above-mentioned deficiency of Isolated Tooth, domestic and international many dentistry
Education sector material damage supply quotient is proposed the acrylic resin tooth of different tooth position, uses for trainer.Existing acrylic resin tooth is with common plastics
Based on production, it is advantageous that Tooth morphology is consistent with people's Tooth morphology, clear typical, the same repeatable white silk in tooth position of anatomical structure
Habit, reasonable price etc., grinding target is not clear enough when shortcoming is trained, and assessment mode still can only be used and be visually observed,
It is difficult to keep assessment result objective, to be unfavorable for guiding the incremental raising operation accuracy of trainee.In addition, hardness and true
Tooth hardness has different, and feel is caused to have certain difference.
In order to keep the evaluation of tooth preparation more objective, occurs digitalized oral cavity teaching evaluation system successively on the market in recent years
System, it is advantageous that carrying out objective mistake to the operation of patient by loading locator and external probe to dental turbo machine
Journey evaluation；Or it is scanned in vitro by the tooth body Model that external scanner completes grinding and realizes objective evaluation of result.
However it also has certain limitation, such as the equipment price of process evaluation high (about 750,000 yuans one, and training
When need one machine of a people), the load of locator cause turbine rearward weight be significantly increased the operation of trainee is brought in turn it is bright
It is larger etc. that aobvious influence, probe signal are easy to be obscured by an object interruption, occupied area；Evaluation of result equipment at work must be
Trainee does not still know specifically how to change after tooth mould takes out the fluency for being put into scanner progress impact evaluation, assessment
Into, complicated operation for evaluation process.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of color partition type tooth preparation training moulds
Type, to keep trainee's grinding with clearly defined objective, and can real-time objective feedback training as a result, incremental raisings of guidance trainee is grasped
Make accuracy.
Color partition type tooth preparation training pattern of the present invention, by the tooth preparation training pattern for corresponding to each tooth position
Composition, the tooth preparation training pattern corresponding to each tooth position are made of fixation section and preparation training section, the preparation instruction
Practicing section is the integration knot that target areas identical by material, that color is different, error permission region and prohibited area are combined into
Structure, the region for needing to abrade when the target area is trained, the region that the error can abrade when region being allowed to be trained,
The region that the prohibited area cannot abrade when being trained, error allow region between target area and prohibited area, and
Around target area.
Above-mentioned color partition type tooth preparation training pattern, error allow the thickness (i.e. error range) in region can basis
The trained degree of trainee investigates requirement setting, generally 0.05~0.8mm.In this error range, it can design and prepare
Different-thickness error allows the tooth preparation training pattern in region, meets the needs of different levels trainee.
Above-mentioned color partition type tooth preparation training pattern, 20 deciduous teeth preparation training patterns or 32 permanent teeths including people
Preparation training pattern.
Above-mentioned color partition type tooth preparation training pattern, making material is engineering plastics, to keep its hardness closer
True tooth, trainee are not affected because trained with clinical feel difference by the operation after training clinically；The work
Engineering plastics can be polyformaldehyde (polyformaldehyde is abbreviated as POM), ABS plastic (acrylonitrile-butadiene-styrene (ABS) modeling
Material) etc..
The preparation method of above-mentioned color partition type tooth preparation training pattern is injection molding or 3D printing.
Color partition type tooth preparation training pattern of the present invention has the advantages that
1, due to tooth preparation training pattern of the present invention preparation training section contain the different target area of color,
Error allows region and prohibited area, therefore is trained using the tooth preparation training pattern, and trainee's grinding is with clearly defined objective,
And can real-time objective feedback training as a result, avoid instructor or the appraiser error as caused by subjective factor, it is unified
Training standard.
2, it is trained using color partition type tooth preparation training pattern of the present invention, trainee can independently practice
And assessment, and correction is made according to tooth body distribution of color in time, incremental raising operates accuracy, thus can not only save significantly
About qualified teachers, and the training burden in the unit time can be obviously improved, and teaching Process of experiment is allowed to become more efficiently, simply.
3, due to use tooth preparation training pattern of the present invention can real-time objective feedback training as a result, because without logical
It crosses digitalized oral cavity Teaching Evaluation System to evaluate training result, can not only save equipment purchase expense, but also training knot
The evaluation method of fruit is more simple, smooth, while trainee knows specifically how to improve.
4, due to the making material of tooth preparation training pattern of the present invention be engineering plastics, thus with existing acrylic resin tooth
Body preparation training pattern is compared, hardness closer to true tooth, can make trainee by the operation after training clinically not because
It is trained to be affected with clinical feel difference.
5, since color partition type tooth preparation training pattern of the present invention can be prepared with 3D printing, thus training content
Training can be made closer to clinical practice situation with personalized designs, in conjunction with clinical case data, further improve training effect
Fruit.
