Definitions
- the sector in which the invention falls is that of dentistry; devices or methods for oral or dental hygiene and more specifically in dental prostheses.
- the object of the invention is splints or prosthetic devices that are used to create veneers injected with fluid composite based on an ideal design of the dental pieces planned by computer.
- Each of these splints is designed with dental treatment design software and manufactured using additive 3D printing techniques, based on an ideal design of the patient's arch.
- Injected composite veneers are thin sheets of resin that adhere to the visible face of the tooth to improve its aesthetic appearance, whether to correct defects such as crooked, broken, separated teeth (diastemas), stained, irregular or worn teeth. Due to their aesthetic purpose, these sheets are placed on the vestibular side of the front teeth, as they are the most visible when we smile. These are elements that are created to measure for each patient so that they look as natural as possible when placed next to the rest of the teeth.
- those injected with fluid resin are the preferred ones in aesthetic treatments since they allow the final result to be predicted and the desired anatomical shape to be transferred from the diagnostic wax-up to a restoration on the tooth surface, predicting the aesthetic appearance to choose the color. and the texture of the restorative material; establishing occlusal parameters such as modifying the position and alignment of teeth, physiological contour, lip profile, position of the incisal edge and gingival orientation.
- this technique can be performed with or without surface preparation, ensures uniform adaptation of the restorative material and increases the potential to design more conservative preparations, since it allows preserving dental tissue and predicting the final result with greater certainty.
- the dental splint is a piece that is used in dental treatments, among others to form a veneer on the teeth. In general, it is a rigid piece, made to measure for the patient, which adapts to his mouth and fits into the denture.
- manufacture of a splint is carried out after a measurement and molding process;
- technology in this field has contributed to the development of splints created from a digital scan of the patient's mouth and computer-aided design with CAD-CAM programs that are subsequently printed using 3D printers by spreading successive layers of additive material to form the previously designed splint.
- 3D printing of splints offers notable advantages: Their production is faster, cheaper and with less discomfort for the patient. In addition, it is possible to obtain more exact pieces and therefore better adapt to the patient.
- Document ES2392303 A1 describes a method for the preparation of a dental correction splint and splint thus obtained, which is based on a patient record by taking an impression of their teeth, where said impression will be processed computerized by processing of the impression image and which includes the creation of a splint based on the computer-treated impression, where externally it will have the potentially expected result of the smile.
- the manufacturing process of injected composite veneers on the teeth is a process that is repeated piece by piece and involves isolating the tooth to be treated by covering the two adjacent pieces with Teflon, placing the splint, injecting the composite resin and Once hardened, remove the splint and repeat the process with another piece until all the pieces to be treated are finished (usually all the teeth in at least one arch).
- Teflon Teflon insulator that surrounds the adjacent teeth
- one objective of the present invention is to provide splints for the construction of injected veneers that prevent the dispersion of the injected material, in order to reduce the dentist's work times by up to 80%, as well as achieve greater definition of the designed teeth and interproximal areas.
- the invention proposes splints for injected composite veneers, which have the characteristics of claim 1.
- splints for injected composite veneers, which have the characteristics of claim 1.
- flexible plastic that adapts perfectly to the patient's already prepared or conditioned teeth, in order to use them as transfer tools for the fluid composite resin that is injected and photocured in the mouth on the teeth conditioned to receive the fluid composite.
- the fluid resin injection process is carried out with these splints in two phases: a first phase in which the veneers are injected into alternate teeth, and a second phase in which they are injected into the teeth not repaired in the first phase. phase, which significantly reduces the dentist's work time.
- the splints As a flexible material is used in the construction of the splints, they adapt perfectly to the teeth, particularly those already repaired in the first phase, this being one of the reasons why the device of constructing two is used. splints per arch to facilitate their separation and extraction after use.
- the first splint has the desired configuration of alternate teeth internally, while in the teeth that are not going to be repaired during this first phase it has a series of windows that bulge outwards in which air remains, which will allow the splint to be easily separated. once the fluid composite resin has been injected and dried, since the air contained in said windows allows the vacuum to be broken created between the splint and the tooth.
- the second splint presents a mold with the final configuration of all the teeth once repaired; those that had already been repaired are protected by the splint itself, given the flexibility of this mold, the others (alternating between those already repaired) are repaired by injecting fluid resin into the mold.
- the second splint and in order to also achieve its separation from the teeth once the fluid composite resin has dried it has also been planned to have windows that define a small cavity for air between the splint and the teeth. teeth repaired in the previous phase, with the purpose described above, of breaking the void between the tooth and the splint and allowing the splint to be separated from the tooth easily.
- the splints of the invention are made based on computer planning, ideal according to the design of the patient's smile.
- the injection splints are made using 3D printing, extending successive layers of additive material until the previously designed splint is formed.
- a type of biocompatible resins are used, more specifically a photopolymer that reacts with ultraviolet light, which is flexible and soft to the touch, with a Shore hardness of 80 a , which simulates the flexibility of rubber or thermoplastic polyurethane, while while combining softness with resistance allows it to withstand bending and compression forces.
- Fig. 1 and 2 show front elevation views of the splints (1) and (2) of the invention, in this example used respectively in the first and second phase of repair of all the teeth (D1-D9). of the upper arch.
- Figs. 3 and 4 correspond to plan views from the underside of the respective ferrules (1) and (2).
- the splints (1, 2) are obtained by direct printing in a transparent material that allows better control of the injection technique.
- direct printing we mean that a positive of the teeth is not first manufactured and the splints are made from it, but rather the splints are the direct result of 3D printing.
- a material that is hard to the touch and at the same time flexible, with high resistance to breakage, is used; More specifically, it is a photopolymer that reacts with ultraviolet light, flexible and soft to the touch, with a Shore hardness of around 80 a , which simulates the flexibility of rubber or thermoplastic polyurethane.
- This material favors the technique and represents an innovation for two reasons: Firstly, it transfers the design accurately when it is directly printed. Secondly, as it is so precise, excess material injected after hardening is carried away with the dislodgement of the ferrule, reducing finishing times.
- the first splint (1) internally presents a mold with at least the desired configuration of the alternate teeth (D1, D3, D5, ...), while in the teeth (D2, D4, D6, ...) it does not will be repaired with this first splint (1), it has a series of windows (4) bulging outwards that form air retaining spaces, which will allow the air contained in said windows to break the vacuum created between the splint and the tooth. in order to allow the splint (1) to be easily separated and removed once the fluid composite resin applied to the teeth (D1, D3, D5, ...) has been injected and dried.
- the second ferrule (2) internally presents a mold with the final configuration of all the teeth; those that had already been repaired (D1, D3, D5, ...) that are protected by the splint itself (2) due to the flexibility of this mold, while the other teeth (D2, D4, D6, ... ), alternating between those repaired in the first phase, are repaired by injecting fluid resin into the mold that makes up said splint (2).
- these splints incorporate windows (4) of various geometric shapes that facilitate the extraction of the splints by breaking the vacuum caused by the maximum definition of the design.
- these windows allow you to identify the teeth where to place the relative insulation with Teflon for the clinical procedure.
- Both splints (1, 2) incorporate injection holes (6) made digitally during their manufacturing with the thickness of the compysite syringe needles, which increases control over the location of the most favorable point for the injection of the composite. from the design, which improves the clinical result, as well as the precision of the diameter of the hole created, avoiding overinjection with the consequent loss of material and excess thickness of the tooth; in addition to reducing work times by avoiding drilling the hole by the clinician.
- the splint (1) that is placed first has holes (6) only in the teeth to be repaired, for easier location of the teeth from a sagittal point of view.
- the splint (2) that is placed second either has holes (6) in the teeth to be repaired, or in all of the teeth.
- both splints (1, 2) with at least one flap (3) on the upper part that will be used as handles to press on to facilitate their removal after injecting the resin that makes up the veneer into the repaired teeth.
- Each splint (1, 2) also includes the name of the case and/or splint number to avoid errors, or they are identified with the patient's name on the front.
