Abstract
Facilitate the spherical structure that telescope denture is dislocated, the metal rack of telescope crown adds a spherical dislocation pearl extended to outside base, the gum end of its position cheek side embrasures between two teeth.The utility model has the advantages that: dislocation force direction basic inside and outside with telescope crown be preced with between dislocate parallel, easily dislocate, facilitate patient to pluck and wear, and to abutment torsionless, available protecting abutment, lengthening sleeve is preced with service life; Be positioned at embrasures, do not hinder buccal mucosa to move, foreign sense, more comfortable; In addition, the design of porcelain aggressiveness material is comparatively attractive in appearance.
Description
Technical field
This utility model belongs to mouth medical technology, is specifically related to telescope denture structure.
Background technology
Telescope denture is the novel movable artificial tooth that development in recent years is got up, the retainer be made up of interior hat, outer hat, and the partly composition such as base, artificial tooth and connector.Interior hat is wrapped on the abutment after preparation, labels in outer hat is enclosed within, by the retention of packing interaction formation closely between inside and outside hat.Have compared with the ring-like removable denture of legacy card retention strong, beautiful and comfortable, to advantages such as abutment torsion are little, be subject to patient favor.
Because inside and outside telescope denture, hat connects closely, retention is comparatively strong, during dislocation near abutment without reliable impetus, saliva of buccal cavity is moistening in addition makes artificial tooth become sliding and wearing patient mostly is the reasons such as old man is handicapped, telescope denture is dislocated difficult.
Current common dislocation mode is that patient passes through to clamp base, by prizing abutment far-end base, artificial tooth is dislocated.But this dislocation mode is dislocated, power and telescope crown road of dislocating forms certain angle, dislocates more difficult, and produces certain side force to abutment and affect health of base tooth and telescope crown service life.Have not yet to see the effective ways or device that facilitate telescope denture to dislocate.
Utility model content
This utility model, for telescope denture dislocation difficulty, unhandy deficiency, designs a kind of spherical structure facilitating telescope denture to dislocate.
This dislocation device does not change basic structure and the Clinical design of telescope denture, only on metal rack, adds a spherical attachment device extended to outside base.
This utility model is achieved through the following technical solutions.
Spherical structure described in the utility model adds a spherical dislocation pearl (also can be referred to as bead) extended to outside base, the gum end of its position cheek side embrasures between two teeth on the metal rack of existing telescope crown.
More specifically, following design can be had.
(1) if only there is an abutment, the cheek side embrasures between abutment and adjacent artificial tooth can be designed.
(2) if two abutments and for facing tooth, the cheek side embrasures between two abutments can be designed.
(3) if two abutments, and between two abutments, missing tooth is more, can design the cheek side embrasures between abutment and adjacent artificial tooth respectively.
(4) if multiple abutment is distributed in dental arch both sides, near the abutment of dental arch both sides, a spherical dislocation pearl can be designed respectively.Particular location is determined according to abutment, and a highest wisdom abutment is canine tooth, can design canine tooth far away in; If the later tooth of canine tooth is abutment, can design abutment near in.
This spherical designs diameter described in the utility model is about 2-3mm, and specifically can accurately find with patient's finger, can apply stable virial, and not hinder buccal mucosa to move, foreign sense is advisable.
The concrete manufacture method of this spherical structure described in the utility model is: embed casting together by design wax pattern when preparing metal rack and formed.
Advantage of the present utility model is as follows.
1. force direction of dislocating basic inside and outside with telescope crown be preced with between dislocate parallel, easily dislocates, facilitate patient to pluck and wear, and to abutment torsionless, available protecting abutment, lengthening sleeve is preced with service life.
2. be positioned at embrasures, do not hinder buccal mucosa to move, foreign sense, more comfortable.In addition, the design of porcelain aggressiveness material is comparatively attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model telescope crown adds spherical restitope pearl.Wherein, 1 is spherical dislocation pearl, and 2 is telescope crown, and 3 is abutment, and 4 is artificial tooth, and 5 is base.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
If Fig. 1 is the structural representation that this utility model telescope crown adds spherical restitope pearl.This utility model adds a spherical dislocation pearl 1 extended to outside base on the metal rack of existing telescope crown 2.The nearly gum end of the cheek side embrasures of this spherical dislocation pearl between telescope crown 2 and artificial tooth 4.Artificial tooth dislocation time with this spherical dislocation pearl 1 for impetus, dislocate in the dislocation direction along telescope crown 2, little to abutment torsion.
Claims (5)
1. the spherical structure facilitating telescope denture to dislocate, the metal rack that it is characterized in that telescope crown adds a spherical dislocation pearl extended to outside base, the gum end of its position cheek side embrasures between two teeth.
2. spherical structure according to claim 1, is characterized in that described spherical dislocation pearl is by following design:
(1) if only there is an abutment, the cheek side embrasures between abutment and adjacent artificial tooth can be designed;
(2) if two abutments and for facing tooth, the cheek side embrasures between two abutments can be designed;
(3) if two abutments, and between two abutments, missing tooth is more, can design the cheek side embrasures between abutment and adjacent artificial tooth respectively;
(4) if multiple abutment is distributed in dental arch both sides, near the abutment of dental arch both sides, a spherical dislocation pearl can be designed respectively.
3. spherical structure according to claim 1, is characterized in that the particular location of described spherical dislocation pearl be abutment is canine tooth, design canine tooth far away in; Tooth after canine tooth is abutment, design abutment near in.
4., according to the spherical structure described in claim 1, its feature is at the gum end of position cheek side embrasures between two teeth being described spherical dislocation pearl.
5. spherical structure according to claim 1, is characterized in that described spherical dislocation pearl diameter is about 2-3mm.
