1 - INTRODUCTION

IMPORTANT NOTE: Before using your BIO-ART articulator, please read carefully all the

Instructions Manual.

The BIO-ART semi-adjustable articulators are Arcon type conventional equipment (models

2000, 4000, A7 Plus and A7 Fix) and Non-Arcon type (models EVA Fix and EVA Plus).

Therefore, the mounting technical procedures are the same for these articulators.

IMPORTANT NOTE: The use of the equipment by professionals not qualified can cause

damage or harm to the product and/or patient.

The articulator is an instrument used to simulate the maxillo-mandibular relation and

movements of a patient in a laboratory, with the purpose of studying the occlusion and

production of dental devices that will be used by the patient. These devices include complete

dentures, partial dentures, bridges, crowns and bite plate, among others.

The face-bow is an instrument used to register the position of the patient's dental arcade in

relation to the skull and transfer this record to the articulator.

This Manual contains only basic and simplified information regarding the use of the

equipment, which do not replace the need of a specific course of Occlusion and/or

Prosthesis, offered in many Teaching Institutions and Dental Faculties, as a compulsory

discipline.

The articulator and face-bow’s use are restricted to qualified professionals.

It is important to emphasize, however, that the semi-adjustable articulator and face-bow

provide a simple, fast and highly precise way of reproducing the human mandible movements,

enabling the dental professional to carry out corrective and restorative dentistry tasks more

easily, rapidly and at lower costs than those of traditional, time-consuming techniques

involving expensive and highly complex equipment. Furthermore, the semi-adjustable

articulator and face-bow produce far more accurate results than those produced by “simple

hinge” articulators, which involve arbitrary mounting of the mandibular cast on the device and

whose movements are also limited.

The use of the semi-adjustable articulator and face-bow is therefore recommended for most

prosthetic, occlusal and rehabilitation work. The technique is simple, fast and easy, offering

highly satisfactory results for both the patient and professional.

FIG. 5 FIG. 6 FIG. 7

2.1 - DENTATE AND PARTIALLY DENTATE PATIENTS

a) By using bite registration material (“godiva”, wax, among others) three points on the fork are made: one frontal point, in the exact centre of the fork, and two points at the back, one at each semi-arch of the fork (fig.1).

b) Position the bite fork so that the midline of the fork handle is aligned with the midline of the maxilla and place it on the upper teeth, holding it firmly in place until the registration material hardens (fig. 2). Only a small amount of registration material should be used since the purpose is to record only the cusp tips of the teeth while keeping the fork as immobile as possible (fig. 3).Afterwards it is advisable to try the cast on the registration to check its stability (absence of clearance) (fig. 4).Note: Alternatively, a pre-impression of the teeth can be made on the upper model and then refined in the mouth. In the case of patients who have partially jagged teeth, it is important to locate points that hold the fork stably in place, despite the missing teeth and the points used for the transfer.

c) Recline the patient in the chair to reduce the induction of tensions on the fork set and face-bow asking him to keep the fork in the same position, supporting the thumbs against the maxilla (fig. 5). Take the face-bow to the patient and introduce the fork fixation assembly into the bite fork handle, assuring that the wing nut is upside down (fig. 6). Then carefully insert the face-bow earpieces into the patient's external auditory meatus as if you were putting a stethoscope into his ears (fig. 7).

FIG. 11

FIG. 12 FIG. 13 FIG. 14

d) Place the nasion relator on the face-bow cross bar, when using the face-bow Standard or on the “W” of the face-bow, when using the Professional Face-Bow. For both models, centre the nosepiece on the patient's nasion. The earpieces should now be carefully positioned as deeply as possible in the patient's auditory meatus and the nosepiece should be gently pressed against the patient's nasion while tightening the wing nuts of the nazion relator assembly (fig. 8). Afterwards, tighten the three screws of the Standard face-bow or the central screw when using the Professional model (fig. 9 and 14).

e) With the nazion relator and the face-bow tightened and the patient holding the fork immobile, push the fork fixation assembly forward, sliding it on the fork handle until it is as close as possible to the lips, without touching them, in order to achieve increased stability. Then tighten the wing nuts of the fork: first the double articulated nut (connection block) (fig. 3) and then the horizontal slide bar nut, so that the fork is supported at one end of its handle, resulting in less tension on it (fig. 10 and 11). To ensure proper registration, ask the patient to remove his thumbs from the bite fork and check if the fork and the face-bow are stable and immobilized (fig. 12).

f) When using the articulator model 4000, record the approximate intercondylar distance, whose reading is taken on the front edge of the face-bow Standard or above the “W” for the Professional face-bow (fig. 13 and 14). The three numbers (1, 2 and 3), separated by a reference mark, correspond to the intercondylar distances: small, medium and large. When the reference mark is aligned with the distance indicator, always use the smallest distance for the patient. This information should be registered in the patient´s records for subsequent adjustment of the articulator.

Note: In other articulator models, the intercondylar distance is fixed at an average of 110mm and the intercondylar distance is not adjustable. In this case, disregard the above-described registration of the face-bow.

2.2 - TOTALLY EDENTURELESS PATIENT

a) When registering totally edentureless patients with the face-bow, use the special edentureless fork, or Conti fork (optional), to maintain the prove plate and roller wax.

b) After the patient's registration on the wax roller, heat both handles of the fork slightly in a flame and press them on the upper wax roller, which was previously joined to the lower wax roller, or not, with the midline of the fork handle aligned with the midline of the patient (fig. 18, 19).

c) Place the set (fork + wax rollers) in the patient's mouth inserting it on the alveolar edges (fig. 20)

Note: When carrying out the registration with wax rollers which were previously joined, ask the patient to keep it in position and close his mouth.

d) Repeat steps (c) to (g) of item 2.1

3 - MOUNTING THE CASTS ON THE ARTICULATOR

3.1 PREPARING THE ARTICULATOR

The adjustments of the articulators mentioned below are only used to mount the casts on the articulator. However, the professional may choose to use other angulation techniques to personalize the settings.

The marks 1, 2 and 3 of the Face Bows are used to adjust the intercondylar distance (small, medium, large), when the mounting is carried out with the Articulator Model 4000. For the other articulators models, it must be ignored.

3.1.1 Articulator Model 4000

a) Fix the condylar elements into the lower frame holes according to the patient's registration (1, 2 and 3) made with the face-bow. With the help of the condylar element shaft, tighten the condylar elements slightly (fig. 21).

b) Adjust the same intercondylar distance in the upper frame, expanding or closing the condylar guide with the micrometric expanding spindle (fig. 22). Note: To facilitate adjustment of the intercondylar distance of the upper frame using the micrometric spindle, leave the wing screw of the condylar guide inclination slightly loose.The relationship between the intercondylar distance and the positioning of the condylar guide is given as follows:*Small = without expansion (condylar guide totally closed)*Medium = first marking on the condylar guide axle*Large = second marking on the condylar guide axle

Important: A fine adjustment should be made to prevent lateral movements of the upper frame in relation to the lower frame observing that the position of the condylar elements should be touching the posterior and superior walls of the condylar guide and the lateral of the bennet angle adjusting device simultaneously (fig. 23) i.e., the reference mark for the adjustment of the intercondylar distance in the condylar guide axle does not always coincide with the correct position of adjustment of the upper frame. A fine adjustment is therefore necessary, using the expanding spindle.

c) Adjust the condylar guide at a 30° angle and a negative “Benett” angle (fig. 24 and 25), assuring the stability of the articulator at a central position and place the spring latch assembly on the lower frame.

3.1.2 - Articulator Model 2000

Adjust the condylar guides at a 50º angle and the immediate side shift at 0 (zero) millimeters. Close the central lock assuring that there are no lateral movements and fasten the condylar guide elastic in the lower frame (fig. 26, 27 and 28).

FIG. 26 FIG. 27 FIG. 28

FIG. 29 FIG. 30 FIG. 31

3.1.3 - Articulator Model A7 PlusTo facilitate the mounting of the casts, adjust the Condylar Guides angles at 30º and the Bennet at 0º (fig. 29 and 30). Then push back the upper part of the central lock until feel the “click” (locked position fig. 31).

PS.: In order to make sure that the Articulator A7 Plus is totally locked at the centric position, check if the 2 locks (left and right) are at the locked position.

FIG. 32 FIG. 33 FIG. 34

3.1.4 - Articulator Model A7 FixAiming as main characteristic simplicity and easiness to work, the A7 Fix Articulator was developed with the Bennet and Condyle angles fixed at the average of 15° and 30°, respectively. The intercondilar distance was also fixed at the average of 110 mm. Therefore, this model does not require preliminary adjustments for these components, such as the other models previously mentioned. In order to lock the Articulator A7 Fix in the centric position, there is an innovative system with two lateral pins, denominated: “centric lock pin”. This pin has 3 main positions: first position - totally closed (locks the articulator in the centric position - picture 32); second position - intermediate (releases the articulation movements - picture 33) and third position (allows to remove the upper from the lower frame - picture 34).

FIG. 36 FIG. 37FIG. 35

IMPORTANT NOTE:

The horizontal slide bar lock screw of the Articulators Model EVA PLus and EVA Fix (see this item on the Part List), are used to calibrate the equipment at the plant and should not be unfasten or removed. This procedure can disadjust the equipment.

FIG. 38

3.1.5 - Articulador Modelo EVA Plus:Adjust the condylar guide at a 30° angle and the “Benett” angle at a 0° (zero) (fig. 35 and 36). Tighten the right and left screws, assuring that there are no lateral movements (fig. 37)

3.1.6 - Articulator Model EVA Fix

Tighten the right and left screws, assuring that there are no lateral movements (fig. 38)

07

08

The Standard face-bow should only be used with the articulator model 2000, 4000 and 5000. It should not be used with the EVA Fix and EVA Plus models.

a) Fix the face-bow Standard to the upper frame of the articulator by fitting the earpiece holes on the small pins located on the external edge of the condylar guide (fig. 39).

b) Support the front part of the Articulator Upper Frame on the cross bar of the face-bow. Close the face-bow firmly by fastening the central face-bow wing nut and placing the whole face-bow together with the upper frame on the lower frame of the articulator (fig. 40,41 and 42).

c) Place the upper cast, with retentions and previously hydrated, on the fork registration. Lift the Upper Frame of the articulator, depositing a small amount of plaster on the Upper Mounting Plate and a portion on the top of the Upper Cast. Then, using one of your hands, keep the fork and the cast in position, avoiding any movement of the Bite Fork and carefully hinge the Upper Frame until it touches the cross bar of the face-bow. Wait for the plaster to harden (fig. 43).

Note: The sides of the mounting plates, which are in contact with the articulator frames, should be devoid of plaster.

Important: In order to achieve greater stability and precision during the transfer procedure, it is advisable to use the Fork Support (optional) and plaster type IV (fig. 44).

d) Remove the face-bow from the articulator.

3.2.2 - Professional face-bow

The main feature of this model is the Jig Transfer Assembly for mounting the casts on the articulator (fig. 45). This assembly is placed in the lower frame of the articulator through the Jig assembly lower base thus eliminating the need for the face-bow arm while transferring the patient's registration onto the articulator and providing quick mounting of the cast, easy handling, greater stability, precision and reliability.

a) Remove the incisal guiding table from the lower frame of the articulator and insert the jig transfer lower base, assuring that the guide pin is properly touching the end of the slot (reference point) (fig. 46,47 and 48).

b) Remove the jig transfer assembly from the face-bow by releasing its respective wing nut, connect it to the jig transfer lower base and fasten the wing nut (fig. 49 and 50).

c) Insert the upper frame support on the jig transfer connection rod, supporting the upper frame and assuring the parallelism among the articulator frames (fig. 51).

FIG. 55

d) Place the upper cast, with retentions and previously hydrated, on the fork registration. Lift the Upper Frame of the articulator, depositing a small amount of plaster on the Upper Mounting Plate and some on the top of the Upper Cast (fig. 52). Then, using one of your hands, keep the fork and the cast in position, avoiding any movement of the Bite Fork and carefully hinge the Upper Frame until it touches the support. Wait for the plaster to harden.

Note: The sides of the mounting plates, which are in contact with the articulator frames, should be devoid of plaster.

Important: In order to achieve greater stability and precision during the transfer procedure, it is advisable to use the Fork Support (optional) and plaster type IV (fig. 53).

3.3 - INTEROCCLUSAL REGISTRATION

To set up the mandibular (lower) cast in the articulator, you should have a record correlating the upper and lower dental arches, according to the purpose of the mounting, in one of the following ways:Maximum Intercuspation (MI);Centric Relation (CR);

These records can be made using material of the operator's preference: wax, resins, addition or condensation silicon, etc. (fig. 54 and 55)

To obtain the M.I registration, place the selected material to register the patient's arcade and ask him to occlude.There are several techniques to obtain the R.C registration, i.e. Peter Dawson's technique (bilateral manipulation of the mandible), Lucia's JIG technique and James Long (use of plastic spacer) among others.

Note: For totally edentureless patients, this registration is made when the upper and lower wax rollers are joined based on the correct dimensions of the patient.

3.4 - MOUNTING THE MANDIBULAR CAST

a) Place the Incisal Guide Pin in the Upper Frame of the

articulator with its rounded tip pointing downward so that

the upper and lower frames are parallel, i.e. on the zero

marking of the Incisal Guide Pin (fig. 56)

b) Now turn the articulator upside down on the laboratory

bench and affirm the lower cast, with retentions and

previously hydrated, upon the interocclusal register that

should be placed in the mounted upper cast (fig. 57). In

totally edentureless patients, this was obtained by

joining the wax rollers together.

c) We recommend fixing the casts with rubber bands or

staples (fixed with “godiva” or wax) so that they remain in

position until the plaster hardens. Place a small amount

of plaster on the lower part of the mandibular cast and a

small amount on the mounting plate of the lower frame of

the articulator to fill in the gap between them (fig. 58).

d) Make sure the condylar elements are duly positioned

and close the lower frame until the Incisal guide pin

touches the Incisal table. Afterwards, fasten the

articulator frames using rubber bands to prevent

possible distortion occurred by the plaster expansion

(fig. 59)

Note: The sides of the mounting plates, which are in

contact with the articulator frames, should be devoid of

plaster.

e) After the plaster hardens, turn the articulator back to its

upright position (lower frame resting on the laboratory

bench) and complete the work, filling the cast fixation

towers with plaster for the finishing touches (fig. 60).

3.5 - FEATURES OF THE RAIL MOUNTING PLATE

The possibility of reusing the Mounting Plate without breaking the model requires care with the side finishing of the plaster on the plate, i.e., the plate should not have plaster at the lateral border (picture 61).

In order to take off the model, the plaster should be removed of from the retention hole (picture 62) and then the model should be hold while tapping the plate towards the indicated arrows located on the lower face of it (picture 63).

PS.: Once the model has been taken off the Mounting Plate, we can not guarantee the returning of it in the initial position with precision, since it depends on the technical quality of the work and the materials used (especially the plaster).

5 - SPECIAL FEATURES OF THE STANDARD ANDPROFESSIONAL FACE-BOWS

5.1 - STANDARD FACE-BOW

The Bio-Art Standard model is simple and easy to work with. It has manually tightened wing nuts to fix the fork, eliminating the inconvenient use of the key. In this model, the registration of the position of the patient's upper dental arcade in relation to the skull is transferred to the articulator by setting the complete face-bow in the upper frame assembly of the articulator (chapter 3 Item 3.2.1)

5.2 - PROFESSIONAL FACE-BOW

The main feature of this model is the Jig Transfer Assembly for mounting the casts on the articulator, eliminating the need for the face-bow arm while transferring the patient's registration, providing greater quality, stability, precision and reliability (ref. chapter 3, item 3.2.2). The design of the face-bow ensures more stability concerning the opening and closing movement in relation to the fork, or in other words, the fork is fixed when the face-bow moves. The auricles are anatomic, removable and chemically sterilized ensuring comfort for the patient.

The Standard Face Bow can be used with the all Articulators models, its use is forbidden with the Models EVA Fix and EVA Plus.

The Professional Face Bow can be used with any Bio-Art Articulator model.Jig Transfer Assembly

7 - SAFETY RULES

• This manual only contains basic and simplified information regarding the use of the instrument and under no circumstances it is a substitute for a proper training course. The articulator and face-bow are products aimed at the exclusive use of qualified dental professionals.

• The Bio-Art face-bow is designed for use with Bio-Art's own articulator and vice-versa. Although, the Standard face-bow is compatible with other articulator models, its use with similar models should be consulted. The Professional face-bow is exclusively designed for use with the Bio-Art articulator. Therefore, Bio- Art does not guarantee precision when its face-bows are used with other products.

• Bio-Art articulators are not interchangeable, i.e. the casts mounted on one articulator model should not be transferred (mounted) to any other articulator. Therefore, Bio-Art does not guarantee precision when casts mounted on one articulator are transferred to another.

• The only Bio-Art articulators, which are interchangeable, are those which are calibrated in the factory. Thus, for safe and precise interchangeability, casts should be transferred only between calibrated articulators.

• Before using the articulator and face-bow, the professional should check the instrument for possible damage, distortion of the incisal pin, face-bow's parallelism, proper centricity of the incisal pin in relation to the lower frame, etc. Should any abnormality be found, Bio-Art's Technical assistance or Authorized Representative should be contacted immediately.

• The face-bow should be cleaned with warm water prior to its use. The Bite Fork must be autoclaved and the Earpieces disinfected with a bactericide or with 70° alcohol.

• Bio-Art recommends only warm water for the general cleaning of the articulator and face- bow.

• When using “godiva” or any other registration material, special care should be taken to avoid excessive heating of the material, which might burn the patient's mouth. Bio-Art urges the user to carefully follow the instructions of the registration material manufacturer.

• Because the articulator is a precision instrument, it should be handled, transported and stored carefully. Bio-Art provides a plastic case (optional accessory) exclusively designed to accommodate the articulator and to facilitate its transportation.
