DD252123A1 - DEVICE FOR THE INTRAORAL REGISTRATION OF SUBWAY MOVEMENTS - Google Patents

Abstract

The invention relates to a device for intra-oral registration of lower jaw movements and comes in a more functional in dentistry oriented approach in diagnostics and therapy of the orofacial organ counter, by the interaction between the occlusion, temporomandibular joint and musculature special care is devoted. The essence of the invention using a support pin carrier system and a Schreibplattentraegersystems is that at least one edge of the carrier system is designed resiliently.

Description

Explanation of the essence of the invention

The object of the invention is the design of a device for intraoral registration of lower jaw movements, which can be used both in full and partially edentulous teeth as well as edentulous patients and this ensures a reproducible fixed and always the same assignment intraoral and gypsum model and the graphical registration both "tooth-guided "and" muskeU / articulated "free mandibular movements allows.

The object is achieved by using a support pin carrier system and a writing board carrier system, in that according to the invention at least one flank of the carrier system is resilient and arranged for anchoring to the teeth, the partial denture or the full denture laterally attachable retention strips with applied autopolymer

It is advantageous if the spring-loaded flank is connected via pins to the carrier system, wherein the pins are slidably mounted in the carrier system and arranged in the springs having a longitudinal bore pins compression springs.

The invention will be explained below in an embodiment.

The application of the device is accordingly the subsequent description. After taking the impression of the dentition situation of the upper and lower jaw and production of the jaw models, the required span of the resilient support pin carrier system is initially set on the upper jaw model by means of a modified Ivory template, taking into account the space available for the LAFOL retention strips. These are then plugged (possibly thinner grind or use expansion strips as an intermediate support for wide mandibular arches) and after application of Äutopolymerisat, which also fills the underarching Zahnbogenbereiche for retention in its plastic phase, the secure fixation is achieved after the curing process. The fixation of the resilient registration plate carrier system takes place analogously at the lower jaw model, whereby the parallel assignment of the two systems is taken into account by means of an assignment element in the occlusion position upper jaw and lower jaw model.

- Serrated attachment bars allow the fixation of the registration devices on bite templates with wax bars. The advantage of the device is based on the spring-like mode of operation, whereby an always the same and thus reproducible and secure anchoring (use unterichgehen dental arch areas) is ensured and additional holding elements (dental braces) are not required. At the same time, it is possible to assign the entire device to the dentition situations fully toothed, partially toothed, partially toothed in combination with removable partial dentures and edentulousness (wax wall anchorage or anchoring to complete dentures).

Apparatus according to claim 1, characterized in that the spring-loaded edge (2) via pins (4) with the carrier system (1) is in communication, wherein the pins (4) are slidably mounted in the carrier system (1) and in the a longitudinal bore having pins (4) compression springs (5) are arranged. For this 1 page drawings Field of application of the invention The invention relates to a device for intraoral registration of lower jaw movements and comes in a more functional in dentistry oriented approach in diagnostics and therapy of the orofacial organ counteracts by the interaction between the occlusion, temporomandibular joint and musculature special care is devoted. The increasing number of patients with functional TMJ disorders and a wide range of unanswered questions make it necessary to have a practice-relevant diagnostic and diagnostic method that can be used in a rational manner. Treatment of dysfunction come to the application. A constructive alternative for the determination of a functionally oriented lower jaw position in relation to the upper jaw is the recording of mandibular border movements by means of the intraoral arrow angle registration. Since disturbances of the symmetry in the movement system of the orofacial organ play an essential role in the development of dysfunctions, the symmetry comparison permits the sweep angle " tooth guided "-" support pin guided "the assessment of occluso-articular conditions and" free "lower jaw movements on their normal behavior (unity of structure and function) or the presence of functional disorders taking into account interrelations of mandibular command values: Tooth management, muscle guidance and joint guidance can thus the diagnostic information content of the Pfeilwinkelregistrate be used for therapeutic purposes. Characteristic of the known state of the art Intraoral arrow angle registration was described as early as the beginning of the 19th century for solving articulation problems by recording mandibular limit movements using a stylus (screw) and an opposing jaw tablet. The known technical solutions of intraoral registration systems or modifications are introduced under the following names: MC Grane cutlery, Gerber Gerber, Gnathometer "M" to Böttger, Occlumeter after Marxkors / Ferger, centric plate system, three-dimensionally adjustable support pin according to Niedermeyer, Functiograph These registration systems have a number of disadvantages, such as the universal use of fully and partially edentulous or fully edentulous registration systems with possible recording of both "tooth-guided" and "post-mandibular" mandibular border movements mostly of metal, which results in damage to the metal surface (abrasion, engraving) in multiple registrations Intraoral Anchoring systems (support systems for recording pen and writing tablet) in full and Teilverzzahnten denture or in combination with partial dentures are only possible through the unrational technological intermediate step of designing plastic carrier templates (additional work by the dental technician). A secure (swing-free) fixation of the support systems is usually possible only by additional holding elements (dental braces), which ultimately results in an uncontrollable disturbance for disability-free "tooth-guided" mandibular movements Releasing with autopolymer intraoral is usually necessary, which results in the problem that for therapeutic purposes the reproducibly same assignment of the carrier templates on the dental models does not correspond to the intraoral positioning or is not even possible Position corrections are only possible in exceptional cases (Nidermeyer system). Object of the invention The aim of the invention is the development of a universally applicable registration system, which allows the practice-relevant requirements by simple handling and high precision, the graphic registration of the lower jaw movements.
