00:29.410 --> 00:32.230
good technique in taking Al Djinnit impressions is

00:32.230 --> 00:35.020
essential for accurate aesthetic impressions.

00:39.290 --> 00:40.610
In many dental offices,

00:40.610 --> 00:43.450
the hygienist is required to take impressions of all

00:43.450 --> 00:46.150
routine patients and of various recall

00:46.150 --> 00:48.400
patients from these impressions.

00:48.400 --> 00:50.850
Stone models are made which aid the dentist and

00:50.850 --> 00:53.700
diagnosis and are used to demonstrate to the

00:53.700 --> 00:56.120
patient what dental work needs to be done.

00:56.650 --> 00:59.630
These models may also be used to demonstrate home

00:59.630 --> 01:02.250
care instructions during individual patient

01:02.250 --> 01:03.030
education.

01:04.860 --> 01:07.510
This videotape will demonstrate the procedure for

01:07.510 --> 01:09.340
taking Al Djinnit impressions.

01:09.770 --> 01:12.090
This involves the measuring and mixing of the

01:12.090 --> 01:14.020
ingredients and the filling,

01:14.030 --> 01:16.990
seating and removing of the tray from the oral cavity.

01:17.790 --> 01:18.590
In addition,

01:18.760 --> 01:21.660
evaluation criteria are presented to enable you

01:21.660 --> 01:24.090
to judge the quality of your own impressions.

01:27.040 --> 01:29.700
After viewing this tape and suitable

01:29.700 --> 01:32.320
practice you should be able to

01:34.900 --> 01:37.690
one dispense and mix al Djinnit impression

01:37.690 --> 01:39.080
materials properly

01:40.560 --> 01:43.310
to accurately fill and seat the impression

01:43.310 --> 01:44.960
tray within the oral cavity.

01:46.360 --> 01:49.320
three remove the impression tray correctly

01:50.800 --> 01:53.160
and for evaluate your impression,

01:53.160 --> 01:55.850
utilizing the specified criteria of a good

01:55.850 --> 01:56.500
impression.

01:58.340 --> 02:01.210
Dental impression materials can be classified as

02:01.210 --> 02:04.210
those that are rigid and those that are flexible

02:04.210 --> 02:06.700
at the time they are removed from the oral cavity.

02:07.540 --> 02:09.930
Dental impression compounds impression

02:09.930 --> 02:12.350
plaster and zinc oxide and Eugene.

02:12.350 --> 02:14.580
All are rigid impression materials.

02:14.770 --> 02:17.250
They are brittle and hard when removed from the oral

02:17.250 --> 02:17.840
cavity.

02:19.510 --> 02:20.890
Augur hydroxyl Lloyd,

02:21.020 --> 02:21.590
Algernon,

02:21.590 --> 02:23.210
hydroxyl Lloyd policy.

02:23.210 --> 02:24.250
Sulfide rubber,

02:24.260 --> 02:24.940
silicone,

02:24.940 --> 02:27.630
rubber and poly ether rubber are flexible

02:27.680 --> 02:29.790
or elastic impression materials.

02:30.180 --> 02:31.160
They have a rubbery,

02:31.160 --> 02:34.050
flexible consistency when removed from the oral

02:34.050 --> 02:34.630
cavity.

02:37.220 --> 02:40.070
Al Djinnit impression material is used to prepare

02:40.070 --> 02:42.520
study models of the entire dental arch.

02:42.950 --> 02:45.890
It is also used for making primary impressions of

02:45.890 --> 02:48.520
evidential ist mouths and to prepare stone

02:48.520 --> 02:51.110
models of patients in the preparation of partial

02:51.110 --> 02:53.590
dentures or athletic mouth protectors.

02:54.000 --> 02:54.530
Al jinn.

02:54.530 --> 02:57.460
It is not recommended for making impressions of cavity

02:57.460 --> 02:58.490
preparations

03:00.460 --> 03:02.410
when selecting the impression tray.

03:02.420 --> 03:05.290
Be sure to use only a perforated tray as it

03:05.290 --> 03:08.110
will better retain the set impression during removal.

03:09.150 --> 03:12.000
Select the appropriate trade for the particular impression

03:12.000 --> 03:12.730
desired,

03:12.920 --> 03:15.890
such as full or quadrant maxillary

03:15.890 --> 03:17.360
or mandibular arch.

03:18.080 --> 03:19.800
Check the size of the tray.

03:19.890 --> 03:22.630
It should be large enough to cover all the teeth and

03:22.630 --> 03:24.310
surrounding oral tissues.

03:27.330 --> 03:30.170
You may extend or deepen the trade by adding either

03:30.170 --> 03:33.090
utility wax or compound to the posterior

03:33.090 --> 03:36.080
rim of the tray compound may be added to the

03:36.080 --> 03:37.520
political region of the trade.

03:37.520 --> 03:39.300
To compensate for a high palate,

03:40.220 --> 03:42.820
Al Djinnit impression material may also be added

03:42.820 --> 03:45.500
directly to the political region of the oral cavity.

03:45.730 --> 03:47.220
Prior to seeding the trade.

03:47.220 --> 03:49.170
To compensate for a high palate,

03:51.030 --> 03:53.920
the tray should not be so large that it is difficult to

03:53.930 --> 03:56.730
insert into the oral cavity or extend

03:56.730 --> 03:58.950
too far from the al villa ridge

04:01.120 --> 04:01.530
trace.

04:01.530 --> 04:04.430
Election depends greatly on the size of the opening to

04:04.430 --> 04:05.440
the oral cavity.

04:09.970 --> 04:12.930
Begin the mixing process by measuring the water

04:12.930 --> 04:15.390
and the vial provided by the manufacturer

04:17.640 --> 04:20.460
note it has three lines indicating the quantity of

04:20.460 --> 04:21.780
water to be used.

04:23.180 --> 04:25.650
The first line is for one scoop of powder,

04:25.950 --> 04:28.840
the second for two scoops and the third

04:28.840 --> 04:29.890
for three scoops,

04:30.530 --> 04:32.290
According to the manufacturer.

04:32.290 --> 04:34.690
The ideal working temperature for the water is

04:34.690 --> 04:36.850
21°C or

04:36.850 --> 04:39.790
70°F. The water

04:39.790 --> 04:42.380
temperature is measured by placing a thermometer in the

04:42.380 --> 04:45.150
vial while running the tap water into the vial and

04:45.150 --> 04:46.420
adjusting it accordingly.

04:47.490 --> 04:50.460
The setting time of algae in it is dependent on the temperature of the

04:50.460 --> 04:50.930
water.

04:51.490 --> 04:52.960
If the water is too warm,

04:52.960 --> 04:54.860
the material will set too rapidly.

04:55.370 --> 04:56.730
If the water is too cold,

04:56.730 --> 04:58.780
it will take longer for the material to set,

04:58.780 --> 05:01.080
which is very uncomfortable for the patient.

05:02.090 --> 05:04.950
The measured water is then poured into a rubber mixing

05:04.950 --> 05:05.400
bowl

05:08.460 --> 05:09.990
before measuring the powder,

05:09.990 --> 05:12.750
fluff it by turning the can over in the back several

05:12.750 --> 05:13.480
times.

05:14.410 --> 05:17.220
Overfill the plastic scoop without compacting the

05:17.220 --> 05:17.730
powder,

05:18.720 --> 05:21.580
tap the handle lightly with a spatula to fill any large

05:21.580 --> 05:22.820
voids in the scoop,

05:23.440 --> 05:26.190
scrape off the excess with the blade of the spatula.

05:27.420 --> 05:30.130
One scoop of powder is used for each line on the

05:30.130 --> 05:30.970
water vial.

05:31.560 --> 05:34.290
One scoop of powder is used for quadrant impression

05:34.290 --> 05:34.860
trays,

05:35.450 --> 05:37.810
two scoops for a mandibular arch tray

05:38.230 --> 05:41.130
and three scoops for a maxillary full arch trey.

05:41.710 --> 05:44.060
Never alter the water powder ratio

05:46.770 --> 05:49.590
begin mixing by adding the powder to the water,

05:50.140 --> 05:51.960
stir to wet all of the powder,

05:52.450 --> 05:55.450
then mixed by squeezing the spatula against the side of

05:55.450 --> 05:57.050
the bowl in a sweeping motion.

05:57.860 --> 06:00.790
Makes for one minute until the consistency is smooth and

06:00.790 --> 06:01.360
creamy.

06:02.750 --> 06:05.330
You will have approximately four minutes total working

06:05.330 --> 06:08.260
time from the moment you begin working to the final set of

06:08.260 --> 06:10.940
the Al Djinnit impression improper

06:10.940 --> 06:13.620
mixing results in grainy impressions with poor

06:13.620 --> 06:15.410
detail if mixed,

06:15.410 --> 06:17.940
either too long or too short a period of time.

06:17.950 --> 06:20.900
The chemical reaction will be affected and the material will lose

06:20.900 --> 06:21.430
strength,

06:23.050 --> 06:25.540
filling the impression tray should be done Quickly,

06:25.770 --> 06:28.150
carry the material on the end of the spatula,

06:28.220 --> 06:31.020
scraping the spatula against the sides of the impression

06:31.020 --> 06:32.070
tray to remove it.

06:32.860 --> 06:35.810
The material is usually added to the posterior portion of the

06:35.810 --> 06:37.540
tray and pushed toward the center.

06:38.500 --> 06:41.180
This reduces overflow and minimizes gagging.

06:44.300 --> 06:47.080
You may smooth the surface of the impression material by

06:47.080 --> 06:49.880
moistening your finger with water and rubbing it across its

06:49.880 --> 06:50.500
surface

06:53.820 --> 06:55.250
before you seek the tray.

06:55.250 --> 06:57.960
The patient should be seated in an upright position with the

06:57.960 --> 07:00.800
mandibular and maxillary arch is in a horizontal

07:00.800 --> 07:01.770
orientation.

07:02.860 --> 07:05.840
This helps prevent the algae in it from flowing in a posterior

07:05.840 --> 07:07.970
direction down the patient's throat.

07:09.140 --> 07:12.120
The patient's teeth should also have been dried using

07:12.120 --> 07:13.760
air or cotton rolls.

07:15.140 --> 07:17.290
Reading the impression area of saliva,

07:17.290 --> 07:19.780
increases the accuracy of the impression.

07:28.870 --> 07:31.530
Seek the posterior portion of the tray first

07:31.710 --> 07:33.440
and then the anterior portion.

07:34.180 --> 07:37.150
Press evenly and use the cheeks and lips to mold

07:37.150 --> 07:38.310
the soft tissues.

07:39.570 --> 07:42.390
Hold the trade gently but firmly in place until

07:42.390 --> 07:45.360
set setting is usually complete within

07:45.360 --> 07:47.990
two minutes it is indicated when the

07:47.990 --> 07:49.710
surface is no longer tacky

07:55.430 --> 07:58.030
removal of the tray from the mouth should be rapid.

07:58.270 --> 08:01.190
Al Djinnit impression material will have less distortion,

08:01.550 --> 08:04.510
less tearing of thin sections and greater strength when it

08:04.510 --> 08:05.160
is deformed.

08:05.160 --> 08:06.610
Suddenly not slow.

08:08.790 --> 08:11.770
First break the seal by moving the cheek or lips away from

08:11.770 --> 08:13.110
the tray with your fingers.

08:13.770 --> 08:16.730
Then remove the tray with a single firm motion.

08:21.670 --> 08:24.620
Hydroxyl Lloyd impression type materials in both

08:24.620 --> 08:25.790
the Auger and al-Jinn.

08:25.790 --> 08:28.700
It forms should be poured within 12 minutes

08:28.700 --> 08:30.400
of their removal from the mouth.

08:33.950 --> 08:36.780
Evaluate the quality of your impression by looking for the

08:36.780 --> 08:38.100
following criteria.

08:38.990 --> 08:40.440
A smooth surface,

08:42.450 --> 08:43.850
a rounded periphery

08:46.570 --> 08:47.870
centered in the tray,

08:50.510 --> 08:52.130
the proper depth in the tray,

08:52.140 --> 08:53.270
one quarter inch,

08:55.560 --> 08:57.150
no debris from the mouth,

08:58.770 --> 09:01.190
good detail including tooth anatomy,

09:01.540 --> 09:01.950
ginger,

09:01.950 --> 09:02.830
ville attachment,

09:03.100 --> 09:04.230
muscle attachment,

09:04.240 --> 09:05.740
and any abnormalities

09:08.870 --> 09:10.670
and normal landmarks,

09:10.680 --> 09:12.450
including retro moller pads,

09:12.860 --> 09:13.300
pistols.

09:13.300 --> 09:15.050
Of the most posterior molars,

09:15.330 --> 09:17.930
and all the sides of the teeth clearly visible.

09:20.810 --> 09:23.370
Once you have obtained an impression which meets these

09:23.370 --> 09:24.280
criteria,

09:24.440 --> 09:26.520
it is ready to be poured in stone
