Abstract
The utility model belongs to occlusal pad when medical instruments field more particularly to a kind of shooting oral cavity CT, and the occlusal pad is in H-type, is equipped with buccal aspect, tongue palatal surface and separating pad, separating pad links into an integrated entity buccal aspect and tongue palatal surface；Separating pad is equipped with upper facing and lower facing, for placing backteeth up and down when shooting.Occlusal pad separation and fixed upper lower tooth occlusion, can be used for the three-dimensional reconstruction of dental articulation.The utility model is practically applicable to tongue or palatine and swells object when carrying out CT or CBCT and checking, separately upper lower teeth, separates tongue body and palatine, to guarantee clearly show the range of lesion in shooting process.
Description
Technical field
The utility model belongs to occlusal pad when medical instruments field more particularly to a kind of shooting oral cavity CT.
Background technique
In the small space in oral cavity, palatine and tongue body are close to each other on anatomic space.As patient oral cavity CT,
In quiescent condition, lip is gently closed, and upper lower teeth is slightly spaced, and palatine surface is bonded with tongue body upper limb, is shot at this time
Oral cavity CT image on, doctor can not separate palatine soft tissue and tongue body tissue.
When lesion occurs for patient's palatine or tongue body, shooting oral cavity CT film is generally required to judge form, the range of lesion
And property.In clinical position, some Radiographers can enjoin patient to protect in order to separate palatine tongue body in CT images
It holds and dehisces to press tongue body position.Due to dehiscing to press tongue body position to be a kind of forced position, patient is difficult for a long time not with the help of external force
It remains stationary, and shoots oral cavity CT and need regular hour (differing within more than ten seconds to tens seconds), therefore tongue palate CT is usually because clap
Patient is mobile and generate motion artifacts when taking the photograph, and influences shooting quality, even results in shooting failure.It is lost in order to avoid oral cavity CT is shot
It loses, more Radiographers still select the traditional CT image pickup method for not changing patient body position, obtained CT figures so more
As making radiodiagnosis doctor and clinician bring difficulty to the judgement of palatine and tongue body lesion.
In recent years, individual Radiographers attempt that patient is allowed to bite cotton roll or ball of yarn to reach point of palatine and tongue body
From since cotton roll or ball of yarn type objects quality are softer, deformation is big when occlusion, and the separating effect of palatine and tongue body is bad, image matter
Measure the guarantee that must also arrive.
Summary of the invention
To solve the above-mentioned problems, the utility model provide it is a kind of shooting oral cavity CT when occlusal pad, oral cavity CT shoot
When use, occlusal pad is placed as between two teeth, and upper lower tooth is engaged and is separated, and avoids generating the staggered superimposed image of cusp nest, together
When the gum for placing occlusal area and cheek side mucous membrane are separated, the clear thickness and form for showing gum.Occlusal pad material is soft
Plastics do not develop in shooting oral cavity CT, but aclusion pads image in the CT image of oral cavity, but upper lower tooth uniformly separates, tooth shape
State is clear, non-overlapping.
Solve occlusal pad when one of the utility model of above technical problem shooting oral cavity CT, it is characterised in that:
The occlusal pad is in H-type, is equipped with buccal aspect, tongue palatal surface and separating pad, and separating pad links into an integrated entity buccal aspect and tongue palatal surface；Point
It is equipped with upper facing and lower facing from pad, for placing backteeth up and down when shooting.Occlusal pad separation and fixed upper lower tooth occlusion, can
Three-dimensional reconstruction for dental articulation.
The separating pad width is accessional teeth cheek palate/tongue side width.
Small consistent, shape is away from shape for the buccal aspect and tongue palatal surface size；Its height is the corona comprising upper and lower backteeth
2/3, keep stability when posterior occlusion up and down.
The separating pad of occlusal pad is located at the middle part between buccal aspect and tongue palatal surface, and it is a rectangle that front, which is seen, above
For upper facing, here is lower facing, main part when being upper and lower posterior occlusion, plays the role of separating upper lower tooth.
The buccal aspect and tongue palatal surface are having a size of long 1.8-2.2cm, width 0.5-0.7cm, high 1.8-2.2cm.
Buccal aspect described in prioritization scheme and tongue palatal surface are having a size of long 2cm, width 0.6cm, high 2cm.
The upper facing and lower facing width are 0.8-1.2cm.
Upper facing described in prioritization scheme and lower facing width are 1cm.
The upper facing of occlusal pad and lower facing equivalent width, corona cheek palate width after being equal to or slightly greater than up and down are basic to protect
Demonstrate,prove the comfort and stability of posterior occlusion up and down.
The tongue palatal surface is equipped with card slot, is located at tongue palatal surface lower end and acts as installing other objects with other objects one
More effects.
The card slot is set among tongue palatal surface lower end, close to lower tooth surface side.
The wide 0.75-0.81cm of card slot, high 0.27-0.3cm, depth 0.4-0.6cm；Card slot is wide in prioritization scheme
0.79cm, high 0.29cm, depth 0.5cm.
Occlusal pad is the solid plastic cushion of an entirety, have it is certain give way and elasticity, can be stung in upper and lower backteeth
When conjunction, stability and comfort are kept.
The utility model form rule, deformation is smaller, can separate palatine and tongue body, while meeting oral occlusion form
Guarantee image quality, is convenient for clinical diagnosis.Utility model selects plastics as material, X-ray can complete penetration, puppet will not be generated
Shadow, the treatment of image photo and clinical diagnosis.And can be disposable a, people one use, it is completely hygienic, it can be avoided iatrogenic sense
The generation of dye.
Occlusal pad is suitable for shooting all patients that oral cavity CT needs separately to be engaged: with palatine or tongue body disease, needing
Shoot the patient for the oral cavity CT for separating palatine and tongue body；It needs to perform an operation guide plate using oral cavity CT data by upper lower tooth
Separated patient；Need to show the patient of local gum form on the CT image of oral cavity.Occlusal pad is suitable for 3 years old all of above year
The patient of age layer.
