TITLE OF INVENTION

DENTAL IMPRESSION IMPLANT TRAY

(Technical Field)

As a dental impression tray exclusively for implants, this

invention forms rectangular and circular shapes on the bottom surface

of the IJ- shaped plastic tray used for the impression material to obtain

impressions of the maxillary and mandibular arch (including the gums

and teeth) surfaces, including numbered markings by ways of rectangular

and circular shapes to indicate the location of needed implant holes such

that when the plastic tray is separated and removed, the end— product is

the Dental Impression Implant Tray.

Furthermore, although it was characteristically impossible for

ready— made trays to form precise implant holes due to the diversity of

teeth— position of each person, this invention allows for the accurate

implant hole locations of teeth of any numbering during the removal of

the rectangular plastic tray. The tray can also be used as an

all— purpose omni— tray for purposes other than implantation.

(Background Art)

This invention is a dental impression tray and is collectively referred to

as an implant for circumstances where the dental patient receives a

dental transplant due to the loss of teeth. Implantation procedures

include the artificial creation of implant holes at the corresponding tray

location of the target region, forming and producing a rectangular or

circular shape. The invention allows for a prompt and precise dental

impression of implant holds at the precise location without needing

additional tools or procedures.

In the circumstances of dental patients with either dental defects or

injuries, a dental molding of the oral cavity and gums is created for the

treatment of the oral cavities by means of impression procedures using

impression materials.

In such cases, trays are used for dental impressions using impression

material, of which either ready— made or custom trays are available.

Implantation procedures require the creation of implant holes by means

of either a drill or abradant. The complexity of the process is the main

cause of long procedure times.

(Disclosure of Invention)

Dental transplants replacing the lost teeth of patients is

collectively referred to as an implant. Implant holes, required for the

implantation procedure, is created at the target location indicated by the

tray and is produced as a either a rectangular or circular formation.

In order to solve the abovementioned issues, this invention includes

numerous rectangular and circular shapes on the plastic tray used for

dental impression of the maxillary and mandibular arches. The implant

hole maker is indicated by a numbering system. Furthermore, when the

impression is separated and removed, the rectangular and circular shapes

indicate the precise location of implantation such that precise implant

hole locations can be created using a quick and easy method.

The rectangular shapes of the implant holes, in specificity, produce 2

separate rectangular implant hold maker shapes.

The size of the implant holes produced are 8mm.

In order to create 8mm implant holes at specific locations, the invention

was produced such that when the two collective squares are separated

and removed into subdivided squares of length 8mm and width 2.5mm

with a lmm distance between each square, squares of height 8mm

(distance lmm+ width 2.5mm+ distance lmm+ width 2.5mm+ distance

lmm) and width 8mm form precise implant holes no matter the location

of the tray.

In addition, by producing the circular shape above the wanted location of

the implant hole, separation is made easier by requiring only a slight

pressure on the centrally located circular hole, the implant hole is easily

formed.

In order to create 8mm implant holes, circular shapes of 5 -6mm

diameters are created on the inside of 8mm diameter circles with 3 — 4

supports. Implant holes of 8mm diameters are created by putting

pressure on the centrally located circular hole and separating the

circular shape.

Furthermore, because the tray is produced using synthesized resin,

manufacturing is easy and can be easily molded to fit the individual

preferences of the medical personnel. Thus, the tray can be used as a

personal tray and also plays the role of an dental impression— purpose

tray.

Figurel -A represents the Implant Hole Maker. C, F, G, and H

(G, H) movements of the impression material. E is a handle created to

support the handle reinforcement. D is a guide for easy finger motions

for an easier mounting of the tray.

Figure2, as a plane view of the mandibular tray, illustrates the

90 supports al, a2, a4, and a5 of the square form (a) that break when

pressurized at the central hole (a3 ). When the 2 square forms (a) are

separated, a single implant hole (b) is formed. Through the use of this

product invention, implant holes for molar teeth and others can be

created in proper locations with higher precision.

95 Figure2— J was invented such that it could be used as either a

support groove for the implant material or to simplify the formation

process of circular implant holes during implantation of the lateral teeth.

square form (a) of the tray floor of Figure4 is produced such that it

separates from the implant hole (b) shown in Figureδ when put under

pressure.

Figureδ is a cross— sectional view of the implant hole of

105 SECTION "B"-"B" of Figure2.

Figureβ is a magnified 4 — directional view of the square form

pressure on both sides can be made. Al , a2, a4, and a5 is produced

with a slight slope on the outside flooring of the tray to allow easy

110 separation.

(Best Mode for Carrying out the Invention)

In order to efficiently create implant holes needed for

implantation procedures on Dental Impression Trays, several square

forms were added to the tray. The tray is produced from synthesized

115 resin and includes a centrally-located square form used for the creation

of the implant hole, which can be lightly pressurized to easily separate

and form the implant hole.

In order to create 8mm implant holes at specific locations, the

invention was produced such that when the two collective squares are

120 separated and removed into subdivided squares of length 8mm and width

2.5mm with a lmm distance between each square, squares of height

8mm ( distance lmm + width 2.5mm + distance lmm + width 2.5mm

+ distance lmm) and width 8mm form precise implant holes no matter

the location of the tray.

125 In addition, by producing the circular shape above the wanted

location of the implant hole, separation is made easier by requiring only

a slight pressure on the centrally located circular hole, the implant hole

is easily formed.

In order to create 8mm implant holes, circular shapes of 5 — 6mm

130 diameters are created on the inside of 8mm diameter circles with 3-4

supports. Implant holes of 8mm diameters are created by putting

pressure on the centrally located circular hole and separating the

circular shape.

Furthermore, because the tray is produced using synthesized

135 resin, manufacturing is easy and can be easily molded to fit the

individual preferences of the medical personnel. Thus, the tray can be

used as a personal tray and also plays the role of an dental impression

-purpose tray.

(Industrial Applicability)

140 The Dental Impression Implant Tray described above is produced

using synthesized resin of affordable pricing, such as polycarbonate,

polystyrene, acetal resin, fluor resin, polyamide, poly— phenylene oxide,

and polysulfone. Thus, in comparison with metal trays, the synthesized

resin tray is more durable, lighter, and easy to manufacture for either

145 personal use or as an all— purpose dental tray, and can also be used in

dental sterilizers (autoclaves).

Furthermore, in terms of dental treatments needed in order to

adjust to the evolution of implantation methods and changes of implant

hole sizes, the invention can be used as a multi-purpose, all-purpose

ray.
