Summary:It is known that articulators are devices designed to reproduce the static and dynamic maxillomandibular movements and positions of a person, because of them it is necessary to take into account the link that exists between these devices and the intermaxillary relations, which are necessary to know, so that the clinician can manipulate the articulators successfully and can have a good result in the treatments performed. The articulator is an essential instrument for working at a certain level. These instruments arose from the need to be able to imitate mandibular movements outside the subject’s mouth. It is considered as a mechanical device with which we can relate the models of the dental arch of the patients to be able to perform diagnostic and therapeutic procedures outside the mouth, and which uses the facial arches to transfer the maxillary model in identical relation to the skull.

How is the bite registration performed?

It’s simple: place the bite registration material on the prepared teeth and instruct the patient to bite down on the material while you check the teeth on the contralateral side (Fig.

Bite registration material

The Glossary of Prosthodontics terms defines occlusal registration as the procedure of recording the positional relationship of teeth or antagonist arches, or as the positional registration of teeth or jaws to each other. (1)

A stable and accurate occlusal record is essential to facilitate the analysis of the patient’s occlusal relationships, either for diagnostic or therapeutic purposes, and allows indirect restorations to be made from the desired occlusal scheme. (2)

Occlusal registration is not only important to record a patient’s own occlusal scheme. In different clinical situations, the dentist may need to modify a patient’s occlusal pattern either in its vertical dimensions or in the sagittal plane. After performing certain maneuvers, the dentist can guide the patient to create a new vertical or sagittal relationship and then record the new occlusal relationships.

Using the occlusal record of the modified pattern, the dental technician can articulately obtain the dentist’s predicted scheme in the dental chair and prepare the required prosthetic restorations or dental appliances based on the information provided by the dentist. (2)

What are occlusal records?

The occlusal registration makes it possible to “replace” the broken leg of the stool, i.e. the missing interocclusal contact that makes the creation of the tripod possible.

What is the bite test?

XIX.

It consists of placing a small wooden wedge between the cusps of a tooth. When pressing on the wood, the fissure tends to open and the patient feels pain. If the result is still not clear, this test can be complemented with dyes such as methylene blue or gentian violet.

What is the purpose of a bite registration?

Bite registration is performed with the aim of analyzing the occlusal relationship on wax, acrylic or silicone, with the purpose of improving intermaxillary relations.

Occlufast bite registration

In the case of registrations made with wax, we cannot speak of stable or resistant registrations, since this material is very sensitive to temperature changes, and therefore easily malleable and deformable. In addition, wax is a very fragile material.

It is therefore highly recommended to make a bite registration with a silicone material such as Futar D Fast. A polyvinylsiloxane material, which allows us to make a perfect reproduction of the occlusal registration. It is an elastomeric addition silicone, with a very high hardness.

This bite registration has a dwell time of 45” and a handling time of 15”. Sufficient time for dispensing the product directly in the mouth and a fast setting time that benefits both patient and dentist.

It is a highly thixotropic material which prevents it from dripping or dripping inside the oral cavity. This thixotropy also allows the silicone bead dispensed to remain stable on the teeth.

How is the bite mark study performed?

The study of this type of bite marks requires determining if the mark was produced by human teeth and indicating the place where it was located; to do so, the bite mark must be photographed from different angles and approaches; once the record is obtained, it is studied by observing the bite marks from different …

How do you take the centric relationship register?

It is based on the fact that the saliva is forced backwards towards the pharynx by the tongue and the mandible is brought back to its physiological centric relation position. The technique consists of placing two wax impingers in the form of a ring in the upper and lower arches.

What are the maxillomandibular relations?

The maxillomandibular relationship in the sagittal plane refers to the anteroposterior position of the maxilla and mandible in the craniofacial complex. In cephalometric analysis it is obtained by determining the discrepancy of points representing the maxilla and/or mandible on a base plane.

Blue wax for bite registration

Fig. 2. Preparation of the coil. Preparation of the patient (fig.3) – Show the patient, with the study models and with the help of a facial mirror, where we want the patient’s jaw to move. We can use the cotton forceps. – The patient should maintain a relaxed posture with the trunk erect. – Talk to the patient in a soft and reassuring tone. – Make him/her practice the movement so that he/she guides the jaw gently according to the verbal instructions. – He should repeat the movement several times and maintain the desired position for a while.

Fig. 3. Preparation of the patient.     Bite registration (fig.4) – Bring the roll into the patient’s mouth. – Instruct the patient to close slowly by guiding him/her with the middle fingers, which raise the upper lip, and the index fingers, which lower the lower lip. – When you want to advance the mandible, place the thumbs behind the chin, and in front when you want to retract it. – The bite is checked by placing it on the plaster models and the vestibular excesses of wax are trimmed before fixing it on the articulator.
