Method for producing an intraoral sleep restoration device in analogue, semi-digital, and digital systems, intraoral device, and positioning jig for intraoral devices

Abstract

The present invention pertains to a method for producing an intraoral device in analogue, semi-digital, and digital systems, by means of a positioning jig for gnatostatic models for making intraoral devices. In the analogue system, the hinge articulator is replaced by the Gnatoforo HT AS in the gnatostatic study and working models, alongside transfer guides of the Camper's Plane (CP) with rods of the positioning jig for intraoral devices, referred to as AS-DIORS. The semi-digital system reduces the number of steps from ten to seven, beginning with a CT scan of the cranium in maximum intercuspation and intraoral scanner, or MPTv. The digital system produces the DIORS in three steps: CT scan of the cranium in maximum intercuspation and intraoral scanner MPTv, processing the 3D images for making gnatostatic models in maximum intercuspation with MPTv, printing of the gnatostatic models, and finally 3D printing of the DIORS.

Description

METHOD FOR PRODUCING AN INTRAORAL SLEEP-RESTORING DEVICE IN ANALOG, SEMI-DIGITAL AND DIGITAL SYSTEMS, INTRAORAL DEVICE AND POSITIONING TEMPLATE FOR INTRAORAL DEVICES. FIELD OF THE INVENTION

[0001] This descriptive report of invention privilege refers to a method for producing an intraoral sleep-restoring device, which can be produced in analog, semi-digital and digital systems, as well as the intraoral device and the positioning template for gnathostatic models for the manufacture of intraoral devices.

[0002] The present invention is situated in the field of dentistry.

[0003] OBJECTIVES OF THE INVENTION

[0004] The objective of the present invention is to provide means, through a production method that facilitates and reduces the production steps of DIORS, enabling their manufacture in analog, semi-digital and digital systems, using means and devices to accelerate such processes.

[0005] The Intraoral Device Positioning Template, developed for the production of intraoral devices and called AS-DIORS, allows the positioning of the gnathostatic model for the fabrication of a Restorative Sleep Intraoral Device (DIORS), in both analog and semi-digital systems.

[0006] STATE OF THE ART

[0007] Document BR 202012025341-6, dated April 19, 2016, concerns a provision introduced into an intraoral device for the treatment of sleep-related breathing disorders.

[0008] FUNDAMENTALS OF THE INVENTION

[0009] In the current state of the art, several problems have been identified regarding the scalability of DIORS production, which prevents this solution from being offered in a more comprehensive area, hindering the mitigation of problems related to Sleep-Related Breathing Disorders such as snoring, obstructive sleep apnea, and sleep bruxism.

[0010] The use of physical materials makes it difficult to maintain the documentation inherent to each case. Dental arch models require physical space and, after use, must be stored to monitor the progress of treatment and to document the proposed solution. Also related to this topic, if primary care is provided in other locations, there would be a need for logistics to ship the arch models to the location where the DIORS (Dental Arch Modeling and Reproduction System) will be produced.

[0011] In the analog system, the study required for the development of the DIORS project demands very specific knowledge that would be difficult to disseminate. Furthermore, in the analog model, it is practically impossible to adopt any automated routine for the design and drawing of each DIORS produced, making it necessary to create each one entirely manually.

[0012] Quality control at DIORS requires production in a location with diverse equipment and qualified personnel possessing highly specific skills, which complicates process distribution and the implementation of production quality control methods.

[0013] Thermoforming proves to be a very satisfactory procedure when it comes to small-scale production of devices, which requires a very high preparation and processing time. Even with a large amount of equipment, it would not be possible to handle high production in a short period, unless a large number of qualified and skilled people were available, which would excessively increase production costs.

[0014] The finishing stage is completely manual, requiring a considerable amount of technical work time, which makes large-scale production unfeasible without excessive consumption of resources, especially labor, which is the main and very expensive component in the DIORS production process, given the need to hire skilled professionals who are not easily found in the job market.

[0015] The number of steps in the processes, as a whole, is very large, which ends up requiring a lot of time in the production of each device.

[0016] METHOD FOR PRODUCTION IN THE ANALOG SYSTEM

[0017] In the proposed analog system production method, molding based on alginate or other material recommended for analog systems is replaced by digitizing the dental arches using a 3D scanner combined with a computed tomography (CT) scan of the skull in maximum intercuspation for complete patient representation and allows the acquisition of the data necessary for device design. These devices can be electronically sent to the DIORS production center without logistical difficulties.

[0018] The study and work model based on plaster casting is replaced by a 3D print of the scanned dental arch, which generates a gnathostatic model in appropriate material that, when made in conjunction with a CT scan of the skull in maximum intercuspation, allows for the necessary studies to be carried out for the parameterization of DIORS.

[0019] The parameterization is done using a computer system that generates the file recognized by the 3D printer (STL).

[0020] In the digital system, thermoforming is replaced by 3D printing of the DIORS, already in its final shape, requiring only minor finishing and polishing procedures.

[0021] From this point onward, in both the analog and semi-digital systems, the fabrication of the DIORS follows the same steps as the fabrication of the DIORS in the old analog system, with one difference: the use of the INTRAORAL DEVICE POSITIONING TEMPLATE, called the AS-DORS Template, described below.

[0022] What differentiates analog and semi-digital systems from digital systems is the incorporation of 3D printing-based production of the intraoral device. This optimized digital system offers the flexibility to have an in-house printing center, or to contract service providers to optimize the analog and semi-digital process using existing equipment that also serves various types of applications.

[0023] To overcome the drawbacks of the current technique, a METHOD FOR PRODUCING INTRAORAL DEVICES (IODs) IN ANALOG, SEMI-DIGITAL AND DIGITAL SYSTEMS was developed, using a POSITIONING TEMPLATE FOR INTRAORAL DEVICES, transitioning from an analog system to a semi-digital and fully digital system.

[0043] PREFERRED DESCRIPTION OF THE INVENTION

[0044] The production method for the intraoral sleep-restoring device, which allows for production in analog, semi-digital, and digital systems, as well as the intraoral device and the intraoral device positioning jig.

[0045] To understand the evolution of the production method of the intraoral device, we will demonstrate how the process worked with the old analog system.

[0046] In order to facilitate understanding of the technical steps in the analog production process and its practical application by a technician with expertise in this technological area of ​​healthcare, the model will be explained below based on the attached drawings, illustrating the developed technology:

[0047] [Fig. 1] – 1st technical step – is the molding, which can be done with alginate or silicone. After molding the dental arches and recording the change in therapeutic analog posture (TAMP) using the George Gauge ruler, measurements of the individual's skull are taken with the facial arch of the HT AS Gnathophore. The George Gauge ruler is used to record TAMP measurements in the mandibular advancement position, which can vary from 50 to 70% advancement. Next, the 2nd technical step – is the fabrication of study and working models of the dental arches, which are obtained from the pouring of plaster.

[0048] [Fig. 2] – 3rd technical step – with the plaster models in hand, the gnathostatic study and working models are made. The gnathostatic model allows us to evaluate the patient's occlusal plane in the three orthogonal planes with reference to the PC. For the fabrication of the gnathostatic study model, we use the HT AS Gnathophore.

[0049] These procedures lead to the constructive details of DIORS, a customized device defined for each patient, which requires the involvement of a qualified professional to define measurements (distances and angles) that will be respected in the production phase of DIORS or any other bimaxillary device that uses these measurements.

[0050] [Fig. 3] – 4th technical stage – based on the previously carried out planning, through the vacuum thermoforming process using PETG type material around 2mm on the rigid outer part and TPU type around 1mm on the soft inner part, obtaining the DIORS in its unfinished state.

[0051] [Fig. 4] to [Fig. 9] - 5th-10th technical stages - After the previous stage is completed, from the fifth to the tenth technical stage, the DIORS goes through the manufacturing process from the disocclusion tracks, union with the mandibular advancement device (arches and tubes) and finishing of the DIORS. ​​The final adaptation is clinical, characterized as the last stage of the DIORS production process. In this stage, small adjustments are made to the device in a fine manner to the patient's dental arches in order to generate adaptation, which is monitored throughout the treatment.

[0052] Before assembling the working model, the upper and lower plates [Fig. 1] are thermoformed in the thermoforming machine, isolating the models to receive the plates, which then undergo a heating and vacuum process. Once the plates are vacuum-formed onto the model, a micromotor, a diamond disc for cutting excess material, and a bushing for smoothing the cut edges are used.

[0053] Before making the working model, a parallelometer is used to draw the PC line on the upper model, which is occluded with the lower gnathostatic model [Fig. 3]. Then, the excess plaster is trimmed along the drawn line and the measurement is checked.

[0054] Next, the upper occlusion tracks parallel to the PC [Fig. 5] are made, adjusting the upper plate installed on the upper model in the PC transfer guide (rear, side and top views). For their fabrication, we used self-curing resin (powder and liquid) and to avoid the formation of bubbles, we used a pressure cooker with 1.5 atm and after acrylicization we applied the finishing touches.

[0055] From this point, we begin assembling the working model onto the hinge articulator, registering the MPTa using the George Gauge ruler [Fig. 6]. The assembly consists of separating the necessary parts of the hinge articulator, using plaster for its fabrication.

[0056] In parallel, the arch former is used to create the dorsal arches. Preparing the telescopic tubes to be subsequently inserted into the device [Fig. 7].

[0057] After the upper tracks are made and the models are mounted on the hinged articulator, the lower tracks are made by placing adhesive tape on the upper track, keeping the resin isolated from the upper track, and the articulator is occluded. After this procedure, the telescopic tubes are installed on the lower plate lingually, in the direction of the lower tracks, also parallel to the PC, and then the pieces are joined with the dorsal arches which will be fixed to the upper plate lingually in the direction of the upper tracks [Fig. 8]. Adhesive tape is used to isolate the tracks in this procedure.

[0058] The finishing of the DIORS [Fig. 9] is done using a micromotor, disc, drill bits and finishing bushings. We also use a polishing lathe with brush and felt, pumice stone and Spanish white.

[0059] These were the steps in the manufacturing process of the analog DIORS using the old method.

[0060] Currently, the analog system has been improved with the replacement of the hinge articulator with the use of the HT AS Gnathophore, for both the study model and the working model.

[0061] The Camper plane (PC) transfer guides are now replaced by the Intraoral Device Positioning Template with a PC transfer guide with double rods, known as AS-DIORS. ​​This Intraoral Device Positioning Template [Fig. 12] to [Fig. 15] is used for both analog and semi-digital systems.

[0062] Analog System: In the method proposed here, the analog system, although optimized, still goes through 10 process steps, demanding a lot of time and labor, making the service more expensive. We highlight the following steps:

[0063] It starts with X-rays and photos (outsourced service);

[0064] Step 1: Molding of the dental arches and recording of the MPT (therapeutic posture change), using the Gauze ruler;

[0065] 2nd stage: construction of the gnathostatic study model with the HT AS gnathophore of Scarlati;

[0066] Step 3: Construction of the gnathostatic working model using the Scarlati HT AS Gnathophore;

[0067] Step 4: Thermoforming of the top and bottom plates;

[0068] Step 5: Transfer of the PC with the parallelometer;

[0069] Step 6: Construction of the upper tracks using the PC transfer guide;

[0070] Step 7: Construction of the lower disocclusion tracks on the hinge articulator;

[0071] Step 8: Construction of the mandibular advancement mechanism: dorsal arches and tubes;

[0072] Step 9: Joining the DIORS to the Intraoral Device Positioning Template [Fig. 12] to [Fig. 15];

[0073] Step 10: Finishing the DIORS.

[0074] Semi-digital System: In this semi-digital system, initially using Scarlati's HT AS gnathophore, it is possible to reduce production costs, generating material savings and reducing the cost of technician and specialist labor hours. In this semi-digital system, the reduction of steps in the DIORS manufacturing process already allows for increased production of units for the market.

[0075] To apply the semi-digital system method in optimizing the DIORS production steps, a device called the Template was developed in response to the need for positioning the device in relation to the chosen cranial reference plane. Currently, static devices (articulators, hinges), with the exception of dental articulators that use facial arches for plane transfers, do not allow the recording of these cranial relationships, hindering the fabrication of intraoral therapeutic devices [Figs. 10 to 15]. This device is an evolution of the process for fabricating disocclusion tracks: from the hinge articulator to the development and testing of disocclusion guides based on the PC [Fig. 10].The first PC transfer guide equipment project, to be developed with a single rod, is for a single model used with a hinge articulator, and the second, with a double rod, is for both models (upper and lower), allowing simultaneous operation. Their bases allow for perfect coupling of the gnathostatic models.

[0076] The use of the INTRAORAL DEVICE POSITIONING TEMPLATE was essential to achieve the improved results according to the proposed analog and semi-digital methods, being more efficient than those obtained by the HT AS Gnathophore [Fig. 2] and [Fig. 10], and by other equipment that maintains the specifications and measurements of the gnathostatic model (Andersen gnathophore cube with a seven-centimeter face), as it allows, in addition to the visualization of the three orthogonal planes, the manipulation and fabrication of intraoral devices with greater dexterity.

[0077] However, according to the technology employed in the INTRAORAL DEVICE POSITIONING TEMPLATE, called AS-DIORS [Fig. 10] to [Fig. 15], its use allows the definition of the upper and lower disocclusion tracks in just one step, and with improved results.

[0078] In addition to its usefulness in the process method, within the Semi-digital System, the AS-DIORS can be used in the construction of a series of intraoral devices, as well as in the optimization of DIORS production in the proposed analog and semi-digital systems. This equipment can be used for any type of treatment that utilizes this craniometric reference, which needs to maintain relationships to those planes, such as in the construction of occlusal rehabilitation with fixed, removable, and implant-supported prostheses parallel to the PC.

[0079] Semi-digital system: in this system the steps in the manufacturing processes have been reduced from 10 steps to just 7, namely:

[0080] It begins with a CT scan of the skull in maximum intercuspation and intraoral MPTRv scanning (virtual therapeutic posture change);

[0081] Step 1: Works with 3D images for the creation of gnathostatic models;

[0082] Step 2: Printing the gnathostatic model;

[0083] Step 3: Thermoforming of the top and bottom plates;

[0084] Step 4: Simultaneous preparation of the upper and lower disocclusion tracks using the Intraoral Device Positioning Template, for the transfer of the PC;

[0085] Step 5: Construction of the mandibular advancement mechanism: dorsal arches and tubes;

[0086] 6th stage: Union of DIORS into AS-DIORS;

[0087] Step 7: Finishing the DIORS.

[0088] Digital System:

[0089] In the digital system method, using digital 3D printing technologies for the device, DIORS will be produced in just 3 steps, namely:

[0090] It begins with a CT scan of the skull in maximum intercuspation and intraoral MPTRv scanning (virtual therapeutic posture change);

[0091] Step 1: Work with the 3D images for creating the gnathostatic models;

[0092] Step 2: Printing the gnathostatic model;

[0093] Step 3: 3D printing of DIORS.

[0094] The development of the DIORS production optimization method has allowed for a significant reduction in the number of production process steps and costs, resulting from the incorporation of modern technologies to replace the old analog methods previously used, and opening up opportunities for future improvements in the functionality of DIORS and other bimaxillary intraoral devices.

[0095] Once the fundamental clinical procedures have been carried out, allowing for the evaluation of each clinical case through the formalization of a diagnosis based on clinical history, radiographic (cephalometric radiography and / or computed tomography), polysomnographic data, and a prognosis, the propaedeutic phase begins with the construction of the intraoral device.

[0096] In the proposed method, using a semi-digital system, it was possible to reduce the steps in the DIORS manufacturing process from 10 to 7 steps, and in the digital system, to 3 steps.

[0097] In the method now proposed, steps in the processes were reduced for both analog and semi-digital systems, given the development of the intraoral device positioning template - AS-DIORS.

[0098] The construction of PC-based occlusion tracks evolved from the first PC transfer guide equipment design, developed with a single rod for a single model used with the hinge articulator, to the second PC transfer guide equipment design, developed with double rods for both models (upper and lower), allowing simultaneous operation when used with the Scarlati AS Gnathophore. Their bases allow for perfect coupling of gnathostatic models, whether these are made with the AS Gnathophore or a similar model that maintains the specifications of the gnathophore cube (7x7 cm).

[0099] The AS-DIORS intraoral device positioning template [Fig. 12] to [Fig. 15] consists of three parallel bases, the lower one with two fixed rods perpendicular to the support plane and the other two bases that slide parallel to the rods. The upper and lower bases have slots so that the base of the Gnathostat made in the HT AS gnathophoron fits perfectly, along with a hollow circular magnet to aid in fixing and removing the models. The middle base has a glass plate where the upper and lower tracks will be made. The models can be positioned in the x, y, and z directions so that access to the track fabrication site is feasible depending on the need. On the sides of the two movable bases, there are screws with the same specifications as the HT AS gnathophoron for fixing them.The rods have millimeter-marked rulers, the glass is approximately 8 mm thick, and the support bars for this glass have a slot with a "small" clearance to allow the glass to slide.

[0100] The template for positioning the dental arch models spatially related to the cranial reference planes [Fig. 12] to [Fig. 15] demonstrates the template in the form of an articulator that receives Gnathostatic models of the dental arches, whose base maintains relationships to the horizontal (PC), frontal and sagittal reference planes of the skull.

[0101] The device, upon receiving the upper and lower models, forms a regular cube measuring seven centimeters on each side, which are spatially related to the aforementioned planes of the human skull. This device allows for the study of occlusal rehabilitation with fixed, removable, and implant-supported prostheses parallel to the PC, as well as the fabrication and installation of accessories for dental appliances, whether orthodontic, orthopedic, for bruxism, or for mandibular advancement, for any type of treatment that utilizes this type of mechanism and needs to maintain relationships with those planes.

[0102] Currently, static devices (articulators, hinges), with the exception of dental articulators that use facial arches for plane transfers, do not allow the recording of these cranial relationships, making it difficult to create intraoral therapeutic devices.

[0103] The dental arch models are positioned to form a regular cube using simple magnetic interlocking mechanisms. Two parallel side rails allow the arches to be separated, facilitating handling during the construction of therapeutic devices without losing the reference of the orientation planes. Additionally, it has an auxiliary horizontal glass plane that facilitates the installation of accessories during device fabrication.

[0104] With reference to the AS-DIORS intraoral device positioning template, the lower base (1) with rails (2) for adapting both the upper base (3) and the auxiliary plane (4) can be observed.

[0105] At the bottom base (1) there is a fitting system with an attached magnet (5) that receives the base of the Gnathostatic model (6).

[0106] The upper part of the device (3), in addition to receiving the base of the gnathostatic model (6) in the same molds as the lower base, is fitted into the rails (2) that run freely to the stop (7) which ensures the formation of the cube. In this way, the upper base (3) runs parallel to the rails (2) which contain a graduation (8) facilitating work on the models (9) as well as the introduction of the auxiliary plane (4) for guidance in the application of accessories in the construction of any therapeutic devices, without losing the reference to the Horizontal plane (10), frontal plane (11) and sagittal plane (12). The vertical adjustment accessories (13) [Fig. 12] allow compensations of the order of 1, 2 and 8 mm.

[0107] The method for optimizing the production of intraoral devices (DIORS), in analog, semi-digital and digital systems, has evolved due to the use of the HT AS Gnathophore and the AS-DIORS Intraoral Device Positioning Template.

[0108] The analog and semi-digital system methods, in addition to using the HT AS Gnathophore, now utilize the AS-DIORS Intraoral Device Positioning Template, which allows for the simultaneous fabrication of upper and lower disocclusion tracks positioned with greater precision in PC transfer, unlike the old analog system where the operation was divided into fabricating the upper disocclusion tracks with a PC transfer guide; and subsequently fabricating the lower disocclusion tracks on the hinge articulator.

[0109] In the steps of the DIORS fabrication method, both in the semi-digital and digital systems [Fig. 14], CT images of the skull in maximum intercuspation, intraoral scanning, and reverse therapeutic posture change by Scarlati, hereinafter referred to as MPTv (virtual therapeutic posture change), are necessary due to the differences in measurements for the fabrication of the mandibular advancement device for the treatment of snoring, obstructive sleep apnea, and bruxism, producing the design of the 3D gnathostatic model, with these measurements for the fabrication of the mandibular advancement device.

[0110] In the steps of the DIORS manufacturing method in the digital system [Fig. 15], 3D images are worked on, designing the device for printing with its constructive characteristics and 3D printer. After designing the gnathostatic model, the designs of the upper and lower plates are made, following the joining system and the specifications of the DIORS characteristics for its 3D printing.

[0111] The digital system optimization method results in a digital printing product containing resin (PU) and plastic or similar product, among other ingredients, capable of producing a printed model with the characteristics of DIORS, achieving the necessary physical characteristics, both externally and internally, in addition to the bacteriostatic and fungistatic resinous adhesive.

[0112] The use of digital systems and 3D printing enabled the development of a 3D DIORS.
