Description
Technical field
The present invention relates to devices when a kind of complete denture restoration for determining upper lower jaw positional relationship.
Background technique
In the presence of natural denture, the positional relationship of upper mandibular is the upper and lower dentition by being in close contact to keep.When complete
After mouth dentition defect, lower jaw loses denture and supports to tie with cusp lock, and meeting is mobile to various positions.Therefore repairing in complete denture
In multiple, it is thus necessary to determine that a stable upper lower jaw positional relationship, i.e., horizontal jaw relationship.Be generally acknowledged that centric relation position, i.e., under
Position after the prominent unrestricted physiology placed in the middle positioned at articular fossa of jaw condyle, be edentulous jaw uniquely can accurately, repeat the position obtained, full mouth justice
Tooth should establish horizontal jaw relationship in centric relation position.
There are many method for determining centric relation position, traditional mode be by hand-made complete denture individual tray,
It is engaged method directly by backteeth to complete.Manual individual tray is by upper jaw individual tray, lower jaw individual tray and lower jaw jaw dike group
At generally by quick moulding material (such as light-cured resin), shaped by hand is made on the plaster cast of complete denture.Backteeth
Being engaged rule is a kind of method for easily determining horizontal jaw relationship.And Gothic bow graphical method is uniquely can intuitively to observe
The method that lower jaw retreats degree and records habitual occlusion position, can more be accurately determined horizontal jaw relationship；But due to
It is complicated for operation, it needs to install on the individual tray made and traces plate and trace needle, it is time-consuming and laborious compared with posterior occlusion method,
It is not widely adopted clinically.Therefore the design for needing a kind of combination Gothic bow and individual tray, saves Gothic bow
Installation process makes to determine that centric relation becomes simple and efficient；Simultaneously using the individual tray made, make producing for final impression
Also it can complete therewith.
3D printing is also referred to as " rapid shaping technique ", and original intention is to realize the quick research and development and manufacture of product.From 20 generation
It has recorded since the eighties, with the raising of digitization modeling precision, the clinic that 3D printing technique takes the lead in entering craniomaxillofacial surgery is controlled
In treatment.3D printing technique can effectively rebuild topography, restore good biomechanical environment, and make on computer
Digital model become doctor within a few hours and can take the physical model of observation, facilitate doctor and case carried out
Personalization assessment treatment.It applies in Prosthodontics field, is expected to replace traditional hand-made complete denture individual tray,
A kind of product for combining individual tray and Gothic bow is produced, the producing efficiency and accuracy of complete denture are greatly improved.
Summary of the invention
In order to overcome the problems, such as conventional method accuracy and inefficient, the present invention provides one kind to be made by 3D printing
, upper jaw individual tray (1) it is compound it is Gothic bow trace plate (2), lower jaw individual tray (4), Gothic bow guide plate (6), in advance at
Trace screw (5) and in advance at fixed ring (7).Individual tray is combined with bow Gothic in mouth, 3D printing one-pass molding, no
Only make the production of individual tray easier to be accurate, also eliminates the installation and debugging of Gothic bow, greatly simplify
Clinical manipulation makes beginner also skillfully can determine horizontal jaw relationship using Gothic bow；It is individual using making simultaneously
Pallet complete producing for final impression can also therewith.
The technical solution adopted by the present invention to solve the technical problems is:
Using the upper lower jaw location determining method of 3D printing complete denture individual tray, which is characterized in that first in determination
Preliminary impression is made under the premise of vertical range, digital scanning preliminary impression generates preliminary cast, according to preliminary cast design and 3D printing

Specific embodiment
Preliminary impression is produced under the premise of determining vertical range first.It will be used to determine the edentulous jaw center support of vertical range
Disk is placed in patient mouthful, and lip is kept to soak and support lip by a lip support arrangement, pallet is left in place 1-2 minutes, so
After measure and mark vertical range.
Pallet is taken out, alginate impression material is packed into, keeps lip to soak and support lip by a lip support arrangement, allows
Patient slowly shuts up, the vertical range until reaching label.Moulage solidification is waited, pallet is taken out, preliminary impression completes.
Then scanning preliminary impression, is designed and the compound Gothic bow of 3D printing production upper jaw individual tray (1) traces plate (2)；
The compound Gothic bow guide plate (6) of lower jaw individual tray (4), prepare in advance at trace screw (5) and fixed ring (7).
It by lower jaw individual tray (4) and Gothic bow guide plate (6) and traces screw (5) and is installed, held in the palm individually with the upper jaw
The compound Gothic bow of disk traces plate (1), Gothic bow is traced plate (2) and worn in patient mouthful together, and screw (5) height is traced in adjustment
To pre-determined vertical range.
In the case where upper and lower jaw individual tray (1), (4) do not depart from contact, before and after advising patient to do lower jaw and left and right sides
Movement.After patient's practice is skilled, tracing plate (2) in the upper jaw has the part for tracing screw (5) movement trace to be coated with special-purpose ink.
It is worn in patient mouthful again, and patient is advised to carry out above-mentioned movement, trace screw (5) i.e. for the various motion profiles of lower jaw
Gothic bow is clearly recorded in trace on plate (2).
Screw (5) is traced when Gothic bow to trace in the Gothic bow of the upper jaw and draw out one on plate (2)When shape,
Vertex is the location of horizontal jaw relationship.Whole devices in outlet, whether observation motion profile is clear, and by lower jaw
Gothic bow guide plate (6) is traced screw (5) and is removed.Stamp is squeezed into upper jaw individual tray (1) and lower jaw individual tray (4)
Material (the light body of such as silicon rubber) is placed again into patient mouthful, advises patient motion lower jaw and tonguing row border molding, and wait stamp
Material is firmly solid.Final impression produces completion at this time.
After moulage is consolidated firmly, upper jaw individual tray (1) and lower jaw individual tray (4) are taken out, it is Gothic to install lower jaw
Formula is bent guide plate (6) and is traced screw (5), and fixed ring (7) is sticked to oral cavity binder (such as glass ion, resin cement)
The Gothic bow of the upper jaw traces plate (2)Shape vertex, vacancy is directed at vertex in fixed ring (7).
Mounted device is placed again into patient mouthful, advises trajectory and velocity of mandibular movements to trace screw (5) to Gothic bow and inserts
Articulation registration material is squeezed into (such as between upper lower jaw individual tray (1) and lower jaw individual tray (4) in the middle vacancy for entering fixed ring (7)
Obite), taken out after device is fixed, be transferred to jaw frame, horizontal jaw relationship record is completed.
