They were immediately disinfected with sodium Hypochlorite and then rinsed.
Surplus and bubbles present in the models were removed in order to eliminate interferences. Figure 1.
Facial arch recording. This was performed with the aim of rectifying the proper mounting of the lower model with the power centric technique.
In order to successfully mount the upper model, information obtained in the facial arch recording of each patient was transferred to the articulator Figure 1. A wax sheet was heated to 53 o so as to be able to bend it and thus obtain a sheet with two wax thicknesses.
After this, it was pre-adjusted in the models in order to obtain a recording of greater precision and comfort for the patient. Wax was once again heated and was carefully inserted in the patient s mouth; the patient was requested to occlude with force into his habitual closing position, until feeling that antagonist occlusal aspects were in contact.
Posterior and lateral excess material was trimmed before wax hardening.
The wax sheet was once again placed into the mouth and care was taken to ascertain that closure was the Figure 2. Bite recording, maximum intercuspation. Once the recording of maximum intercuspation for record taking of both techniques was obtained, a roll of cotton was placed between patient s incisors for fi ve minutes before initiating the procedure. Recording at CR; centric power technique In order to record bite patterns, two segments of blue Delar wax were used for each patient.
Palatal extension varied according to the patient s overjet. The posterior segment was built with two wax thicknesses; this segment spanned from the right second premolar and fi rst molar to the contra-lateral teeth. Following this, the patient was placed in a recumbent position at 45 o with respect to the fl oor.
Wax was heated at 53 o C and was then taken to the patient s mouth. Once the wax s anterior segment was placed, the operator guided the mandible to centric relation, seating the condyles in an upwards direction and guiding the progonion downwards.
Immediately after this, the patient was instructed to close the mandible until posterior teeth reached a 2 mm disocclusion. The anterior block was cooled with compressed air before being removed; once removed, the block was immersed in water and ice in order to avoid deformation Figure 3. After this, the posterior segment was heated to a 53 o C temperature, to be then placed on the upper teeth. Once the posterior segment was in position, the anterior block was once again placed on the upper arch.
The patient was once again guided to mandibular closure until feeling contact of lower incisors within the anterior block. Materials were once more cooled before and after inserting them in the mouth Figure 4. Once the recording was achieved, wax sections were adjusted with the aim of freeing interferences. The lower model was then mounted using the split-cast method to rectify the procedure. Figure 3. Centric relation recording. Power centric technique, anterior block. Figure 4.

Once the centric lock was in place, the plates were placed into the patient s mouth and it was ascertained that the rod occluded into its orifi ce. Figure 7. Fixation of centric lock in tracing vertex centric relation.
Gothic arch tracing, B. Centric lock fixed in tracing vertex. Recording at CR: gothic arch tracing technique In order to record centric relation with the gothic arch technique. Dentsply commercial recording sheets were used. These sheets were individually adapted to each patient; this was achieved with the use of a set of A B plaster models mounted on a hinged articulator set at maximum intercuspation and with Nictone clear selfcuring acrylic to achieve individualization Figure 5. Before placing the lower plate into the patient s mouth it was tinted with a black indelible marker, bearing in mind that mandibular movements were traced on this surface.
The patient was placed in a 90 o position with respect to the fl oor, and the upper plate with the marker rod was placed. After this, the lower plate was introduced in the lower arch. The patient was then instructed to occlude until the upper rod would contact the lower plate. The patient was then instructed to perform protrusion and laterality movements for two minutes, without separating the plates.
Lacks of contact and interferences were carefully monitored during the record taking, so as to guarantee that contact would only take place between the rod and the lower plate Figure 6.
Once the tracing was obtained, the lower plate was removed and the centric lock was placed. This centric lock is an acrylic appliance containing one perforation, which was placed and secured with wax exactly at the vertex of the gothic arch tracing, this is better known as centric relation Figure 7.

API recording format. In this position snow-white type plaster was laterally injected; this was performed with the aim of obtaining mounting guides for the lower model.
After four minutes, when the plaster had set, plates and gothic arch tracing guides were removed in order to perform adjustments. Mounting of the lower model was achieved with the use of plates along with obtained plaster guides.
This enabled achievement of greater precision at the moment of conducting the procedure Figures 9 and Once the recordings were completed and the mountings were achieved, measurements of detected occlusal fi ndings were undertaken. With the help of a millimeter digital gauge and a condylar axial position indicator API , condylar level saggital, vertical and transversal distractions could be measured Figure Obtained measurements were compared and rectified in order to decrease error possibilities.
Afterwards, they were concentrated into the database to be later statistically analyzed. Assessment of two techniques for the recording of mandibular central relationship Table I.
Subject distribution according to age and gender. Table III. Age in years Female Male A total of 30 mountings were performed in 15 bone class II patients, eight were female With respect to horizontal overbite at MIC maximum intercuspation the following was obtained: mean of 4 mm, maximum 7 mm and minimum 2 mm. The diagnosis and rehabilitation process requires a proper planning and modeling of the study cast between the laboratory technician, the surgeon and the prosthodontist for the prosthetic study to generate correct impressions and appropriate intermaxillary records [ 67 ].
I agree to the. Therefore, when screwing the structure, tensile stress and bending forces are produced on dental implants and consequent transfer of tensional forces to the bony support of maxilla and mandible. Los composites M Silverman: Conclusions The possibility of obtaining dental casts without analogs provides a faster, more accurate articuladlres, of course, a lower cost process.
Besides this, there is an angle which is formed between the condyle trajectory in a protrusion movement and a laterality movement. Summing artixuladores, the semiadjustable articulators let the adjustment of the condylar slope, which is straight generally it is curve for some articulators, what it does not represent any disadvantage, because it is not the real one for the patient. Real cases of digital master casts for multiple dental implant restorations.

The traditional crown fabrication process includes: Cemented prostheses on a natural tooth are fixed using between stump carved tooth and crown cementation. Refine your search for plano. Method From a digital process, the relative positions of dental implants, soft tissue and adjacent teeth of edentulous or partially edentulous patients has been captured, and a maser working model which accurately replicates data relating to the patients oral cavity has been through treatment of three-dimensional digital data.
Considering these data and the articulator described by Evens, Bonwill built an articulator artuculadores obtain a balanced occlusion figure 2.
Compared with the conventional master cast, the results show a significant cost savings in attachments, as well as an increase in the quality of semiajustable and accuracy of the master cast, with the consequent reduction in the number of patient consultation visits. These methods can be divided into two categories: Photogrammetry in digital semiajstables All these problems can be avoided by the use of the methodology proposed: Lauritzen which is very similar to Artlculadores H2 and it has a slightly curved incissal shoot.

He described the mandibular movement in two phases: M2 nuts Fig 2 have been chosen. The work presented was carried out within the cooperation agreement established between the following entities: However, the shift angle lets the fixing of Bennet movement direction.
