3. PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the nature of this invention and the manner in which it is to be performed:

4. TECHNICAL FIELD
This invention relates to medical science; specifically to the field of dental science. This articulator has been invented to simulate the stomatognathic system.
This machine is to be used to mimic the articulating system of the oral cavity and helps in the personalized alignment of the teeth according to each patient.

5. Prior Art:
An articulator is defined as a mechanical instrument that represents the temporomandibular joints and jaws, to which maxillary and mandibular casts may be attached to simulate some or all mandibular movement.
There have been many major modifications and inventions in this field of stomato-mechanics in order to facilitate the orientation of the jaws during static and functional movements.
Drawbacks of Existing Methods of measuring wear –
The current mean value articulator is a simplistic design which is utilized by many undergraduates and postgraduates for mounting casts followed by various teeth arrangements. The lack of a few tools may hamper the orientation of the casts before mounting and hold it in position. The inaccuracy of ‘thread relation’ for determining the occlusal plane is well known. Teeth arrangement has been performed since decades according to the glass plate relation while working on the mean value articulator. This arbitrary method of mounting and teeth arrangement, both are overcome in this invention.

6. Objective:
The main objective of the present invention is to provide a novel machine which aids in simulating the temporo-mandibular joint and jaws by using with high accuracy tool for precise & easy mounting & compensatory curved plates for detailed teeth arrangement.
Yet another object of the present invention is to make an articulator that makes orientation
and midline location accurate along with a precise occlusal plane provider and compensatory
curve plate.
Yet another object is to provide a process wherein, this customized mean value articulator consists of an aluminium framework which houses an upper and lower member containing mounting plates for the casts.
Yet another object of the present invention is to provide a process wherein, it has an occlusal plane orientor which will help in accurate positioning of the casts during mounting.
Yet another object of the present invention is to provide a process wherein, it has a compensatory plate provided to apply the compensatory curves to the try in dentures for teeth arrangement.
Yet another object of the present invention is to provide a process wherein, the lingual midline indicator helps in locating the accurate midline along with the incisal pin provided anteriorly.

7. Statement:
Accordingly the present invention provides the gen-next articulator which comprises:
1) The Compensatory Curve plates compensates for the curve of Wilson and Curve of Spee which together comprise the Curve of Monsoon.
2) Occlusal Plane Orientor helps in the placement and orientation of the casts during mounting. This establishes a horizontal guide in order to recognise any deviation from the original position.
3) Lingual midline indicator
4) A Pinrest to support all of the above,
5) The Upper and Lower members of an articulator.
6) The articulator also contains fixed condylar guidance.
7) The entire articulator is supported through the L-frame.
The Aluminium framework which is weighted to lend stability to the entire machine so as to prevent toppling and even due to its light weight. The upper and lower members (15 & 7) contain the mounting plates (8) which will help in the mounting of casts and retaining it. The L- frame helps in supporting the entire assembly. The Incisal Guide (9) table rests the Incisal Rod (10) and the Incisal Pin (11). It is static and not customizable. The Incisal Rod (9) supports the Incisal pin (11). The posterior rod is called the Pinrest (1) which supports all the thumbscrews (3, 14 & 16) of the assembly. The right and left Occlusal Plane Orientor (4, 5, 13) help in the precise orientation of the casts during mounting. The Lingual Midline Locator (12) has a slit to slide in the compensatory curve plates (6 & 17). The condylar guidance (2) simulates the temporomandibular joint. Hence, it opens and closes the articulator.
Procedure:
After the jaw relations procedure, casts should be placed on the wax studs to orient the casts for mounting. The occlusal plane should coincide with the occlusal plane orientor, lingual midline locator and the incisal pin (3- point guidance). This is a more accurate method compared to the arbitrary thread relation we use. After coinciding the occlusal plane orientors then proceed ahead with the mounting. The plaster should be mixed with the water powder ratio provided by the manufacturer. After skillful mixing, load the material on the casts and wait for it to set accurately.
After the setting of the material, teeth arrangement is commenced. Arrange the anterior teeth precisely after which the posterior teeth should be arranged according to the compensatory curved plates inserted into the lingual midline locator. The arrangement automatically sets in the direction of the desired compensatory curve of specific dimensions. The flat plates provided in the assembly help in the mounting of single complete dentures.
