Description

[Technical Field]

[0001] The present invention relates to dental restoration systems and methods for constructing dental restorations that, after being placed in a patient's jaw, can be used to replace one or more teeth while one or more dental implants are healing. [Background technology]

[0002] Today, implant-supported dentures are often the treatment of choice when patients need to replace one or more teeth, especially when certain clinical conditions, such as underlying healthy bone and soft tissue structure, must be met so that the result is a natural-feeling, stable restoration.

[0003] Dental implants usually take the form of a threaded element designed to be placed in the patient's jaw. Implant placement generally requires the opening of a gingival flap to improve access to the implant area. Regardless of whether a submucosal or transmucosal approach is followed, i.e., whether a two-stage surgical intervention or a one-stage flap opening is performed on the gingival soft tissue, a so-called healing cap or healing abutment, more commonly also called a gingival prepear, is typically attached to the inserted implant. The function of the healing cap or abutment is to preserve and hold in place the gingival tissue at the implant site, i.e., in the area surrounding the missing tooth socket, thereby maintaining the anatomical emergence profile.

[0004] The temporary application of healing caps or gingival prep devices aims to create the desired shape of the emergence profile that is deemed appropriate for the specific patient situation. In the field of implantology, this gingival shaping is also referred to as soft tissue conditioning.

[0005] In general, restorative dental treatment involves additional processes or steps in addition to implant healing and soft tissue conditioning. For example, it is often desirable to design and construct dental restorations based on the specific situation in the patient's mouth. To this end, the situation at hand is scanned with an intraoral scanner, or a model casting is made using an impression taken inside the mouth.

[0006] Additionally, during the healing process of an implant into the bone, stress must be avoided to allow for proper healing. More specifically, to allow for proper healing of the implant into the jaw, it is necessary to ensure that the load or mechanical stress applied to the implant does not exceed a certain level. At the same time, while the healing process of an implant can take several months, patients must chew as normally as possible to prevent collateral damage, such as stress on other teeth. Furthermore, during chewing, food and other debris can move into the gap, placing stress on the gap. This can cause inflammation or other problems with the gums or implant, impairing healing.

[0007] Furthermore, constructing a dental restoration on an abutment, such as a temporary abutment, is often difficult or time-consuming. Constructing a dental restoration typically requires the removal and eventual reinstallation of a healing cap, which can stress the soft tissue and potentially affect the healing of the implant into the jaw. This is especially true because the healing cap or abutment is typically removed by grasping it from the outside, which requires removing, moving, or lifting the soft tissue around the healing cap or abutment to some degree. Each removal and reinstallation carries the risk of injuring the gums and weakening or dislocating the implant's connection to the jaw.

[0008] Therefore, there is a need for a system or method that allows gentle handling of the soft tissue and implant situation during implant healing and construction of the dental restoration. Summary of the Invention

[0009] According to the present invention, this need is solved by a dental restoration system as defined by the features of independent claim 1 and by a method for constructing a dental restoration on an implant placed in a patient's jaw as defined by the features of independent claim 13. Preferred embodiments are the subject of the dependent claims.

[0010] In particular, in one aspect, the present invention is a dental restoration system for restoring a tooth at least during healing of an implant structure placed in a patient's jaw, the system comprising a crown abutment and a locking member. The crown abutment is configured to be placed on a gingival former attached to the implant. The locking member has a contact surface and an anchoring structure configured to be secured to the gingival former. The crown abutment has a throughbore configured to receive the locking member such that the contact surface of the locking member contacts the crown abutment and the anchoring structure extends at least partially from the crown abutment. The crown abutment is made of an abutment material configured to bond with a crown material used to construct the crown.

[0011] The dental restoration system may be a temporary dental restoration system. In particular, the dental restoration system may be configured to temporarily replace a tooth or teeth while the implant is healing in the patient's jaw. The time required for complete healing of the implant may take several months, such as between about 3 months and about 10 months.

[0012] Dental restorative systems may be embodied to replace a single tooth or multiple teeth, and thus may have or be combined with crown-like or bridge-like structures.

[0013] The gingival former may be a healing abutment that is placed directly on the implant and fixed thereto. More specifically, in the context of the present invention, the term "gingival former" relates to an element or device designed to be placed on the implant structure after its insertion during healing for the purpose of conditioning the soft tissue. For example, the gingival former may be essentially cylindrical or of a regular shape. However, the gingival former may more advantageously be shaped to reflect the shape of the gingival channel into which the implant structure will be inserted after surgical opening of the gingival flap. Possible types of gingival formers include healing caps, healing abutments, and similar elements.

[0014] An implant structure may include one or more implants in the more literal sense, which are post- or screw-like elements inserted into the jawbone as artificial tooth roots. It may also include an abutment or base fixed to the implant or to at least one remaining tooth. For example, an implant structure may include a base abutment, made of, for example, titanium, designed to be placed on the implant and support a dental restoration or prosthetic reconstruction, such as a crown or bridge.

[0015] The term "dental restoration" in the context of the present invention relates to a structure that includes a visible portion extending into the oral cavity, such as one or more artificial teeth. This term covers crowns, bridges, etc., and similar restorations. Dental restorations are generally individually formed taking into account the given situation in the oral cavity in which the dental restoration is placed. Therefore, the restoration according to the present invention may be a particularly patient-specific individual restoration.

[0016] The term "crown" as used herein generally relates to an artificial dental crown. Thus, as part of a dental restoration, a crown generally is or includes the visible portion of a tooth that extends into the oral cavity. Generally, a crown is an artificial dental portion intended to replace the natural crown of a single tooth. However, the term may also cover embodiments that replace the natural crowns of multiple teeth.

[0017] The term "jaw" is understood herein to include the jawbone, associated soft tissues, and teeth, including their roots.

[0018] Advantageously, the locking member is substantially post-shaped. The securing structure may, for example, comprise a screw thread located around the post, whereby the locking member may be a locking screw or similar screw-like structure.

[0019] Because crown abutments are specially designed to be placed and secured onto a gingival former, they may be suitable for temporary restorations during implant healing. Made from an abutment material specifically designed to bond with the crown material used to construct the crown, the crown abutment allows for the efficient formation of a crown or dental restoration directly on the crown abutment. In this way, a dental restoration or crown can be efficiently created on the dental abutment, while the latter is connected to the implant structure, without the need to remove the crown abutment. This allows for the gentle formation of the dental restoration without undue stress on the implant or surrounding tissue during healing.

[0020] Furthermore, due to the fact that the crown abutment is suitable for forming a crown directly thereon, particularly precise shaping of the crown can be achieved, so that the dental restoration or crown can be specifically embodied and stress on the implant can be reduced. In particular, the invention makes it possible to efficiently and accurately construct temporary restorations that can take into account the specific needs during the healing of the implant.

[0021] The system according to the invention therefore allows gentle handling of the soft tissue and implant situation during healing of the implant and during construction of the dental restoration or crown.

[0022] The term "bonding" in relation to abutment materials and crown materials refers to a fixed connection between the crown abutment and the crown. The fixed connection may be a cohesive and / or bonded connection, which can be created, in particular, by exogenous energy input, such as light or ultrasound. Therefore, the term specifically covers bonding or partially dissolving the crown and abutment materials. In particular, when bonding the abutment material and the crown material, they may interact directly, such that no additional adhesive is required to connect the crown abutment and the crown. More specifically, the crown can be formed directly on the crown abutment, for example, layer by layer. At the end of the crown formation, the crown abutment and the crown can be monolithically and irreversibly connected.

[0023] To initiate the bonding process that connects the crown material to the abutment material, it may be necessary to provide activation energy. For example, such activation may be triggered by heat, or more advantageously by light if applied directly to the patient's mouth.

[0024] The crown material may be light-curable, and the abutment material may be configured to allow the crown material to harden directly on the crown abutment. In this manner, the crown may be fabricated or formed on the crown abutment by well-established techniques known to dentists, i.e., techniques involving light curing. Preferably, the crown material is a composite material, more preferably a resin-based composite material. Such composite materials may have suitable properties for constructing a crown. Among other things, such composite materials may be flexible and formable before hardening, be efficiently cured, e.g., by light, and be sufficiently rigid and biocompatible after hardening to be applied to a patient's mouth.

[0025] Advantageously, the dental restoration system includes a crown material. For example, the crown material may be provided in a paste form that is applied directly to the crown abutment by the practitioner or dentist. In this way, it can be ensured that the crown material and the abutment material are compatible with each other and that a proper bond is achieved.

[0026] In a preferred embodiment, the dental restoration system includes a pin, the pin having a fixing structure corresponding to the fixing structure of the locking member, and the pin is configured to extend through the through-hole of the crown abutment and protrude above the crown abutment when the crown abutment is placed on the gingival former and the fixing structure of the pin engages with the gingival former, whereby the pin is preferably made of a pin material configured not to bond with the crown material used to construct the crown.

[0027] The pin extends through the through-hole of the crown abutment and is provided to be fixed to the gingival former when a crown is constructed on the crown abutment. In this way, the through-hole of the crown abutment can be efficiently freed from the crown material. Furthermore, since the pin protrudes above the crown abutment when fixed to the gingival former, a straight channel can be formed in the crown. Therefore, after the crown is constructed, a channel is provided through which the through-hole of the crown abutment can be accessed. The channel and the through-hole form a single passageway in which a locking member can be provided to attach the crown together with the crown abutment to the gingival former.

[0028] Thus, in an advantageous embodiment, the dental restoration system includes a crown material for constructing a crown, the pin material being configured not to bond with the crown material, and the abutment material being configured to bond with the crown material when constructing the crown.

[0029] In particular, if a crown is formed directly on a crown abutment, such that the crown and crown abutment form a single unit, forces applied to the crown may be transmitted directly to the implant structure via the gingival former. This can stress the healing of the implant into the jawbone, potentially resulting in, for example, compromised stability or tolerance of the implant structure within the jaw. To address this, the locking member preferably has a breakage structure configured to break at a predetermined threshold load applied to the crown abutment when the locking member secures the crown abutment to the gingival former.

[0030] The threshold load may be particularly relevant to the force or load applied to the crown and crown abutment when secured to the implant structure by the locking member. The fracture structure thereby prevents the implant structure from being subjected to loads higher than the predetermined threshold load during healing. In this way, the healing process can be prevented from being stopped or affected by mechanical stresses applied via the crown abutment and gingival former. This may be particularly beneficial in the context of a crown formed directly on a crown abutment, so that forces can be directly transmitted.

[0031] Thereby, preferably, the locking member has an attachment tool shape configured to be connected to an attachment tool for securing the locking member to the gingival former, the attachment tool shape being located on a first side of the break structure, and the locking member has an auxiliary tool shape configured to be connected to a removal tool for removing the locking member from the gingival former when the break structure is broken, the auxiliary tool shape being located on another second side of the break structure opposite the first side of the break structure.

[0032] The attachment tool feature may be located at or near the oral end of the locking member, whereby the term "oral" refers to a distal side or direction toward the patient's oral cavity, as opposed to specifically a distal side or distal direction.

[0033] The attachment tool shape can be any structure that allows the attachment tool to engage with the locking member to secure the locking member to the gingival former. The attachment tool shape can be a screw head-like portion with a recess corresponding to the shape of the portion of the attachment tool that is connected to the locking member. In this way, the attachment tool shape can be embodied as a female mating part. Also, the shape of the recess can match the shape of a standard attachment tool.

[0034] The auxiliary tool shape can be any structure that allows a removal tool to engage with the locking member to remove the locking member after the brake structure has been broken. The removal tool shape can be a screw head-like portion having an outer shape corresponding to the shape of the removal tool to be connected. In this way, the auxiliary tool shape can be embodied as a male engaging portion, and the outer shape can match the shape of a standard removal tool.

[0035] By providing two separate tool shapes, i.e., an attachment tool shape and an auxiliary tool shape, proper periodic attachment and detachment can be achieved through the through-hole of the crown abutment, and more specifically, proper removal can be achieved even if the locking member is broken by excessive load. In particular, after the locking member is broken, the crown is removed together with the crown abutment and part of the locking member. The auxiliary tool shape allows the gingival former to be released and removed from the implant structure without the need for tedious cutting, drilling, or other material removal processes to remove the gingival former.

[0036] Thereby, the locking member is preferably arranged such that the breaking structure is located distally from the installation tool shape, the auxiliary tool shape is located distally from the breaking structure, and the fixation structure is located distally from the auxiliary tool shape. In this way, it can be efficiently achieved that the auxiliary tool shape remains accessible even after the locking member is broken. Therefore, the part of the locking member that is still connected to the implant structure after the locking member is broken can be appropriately released so that the formed gingiva can be safely removed from the implant structure.

[0037] Preferably, the break structure of the locking member includes a weakened section of reduced diameter relative to other sections of the locking member, which allows for a precise definition of a threshold load that limits the maximum load that can be applied to the implant construct.

[0038] Additionally or alternatively, the break structure of the locking member is preferably made of a weaker material compared to the other sections of the locking member. The weaker material may be a material that is literally different from the material of the other sections of the locking member. It may also be the same material with a different general or chemical structure. For example, the weaker material may be the same material as the other sections of the locking member, but with pores or similar cavities / openings to achieve the weaker structure.

[0039] Instead of a gingival preformer, it may also be used with a crown abutment, whereby the dental restoration can be intended as a permanent or temporary restoration.

[0040] Preferably, the dental restoration system comprises a gingival former having an implant structure configured to position the gingival former over an implant structure placed in the patient's jaw, and an emergence profile portion configured to be placed within the patient's gingiva when the gingival former is attached to the implant structure. Incorporating the gingival former into the dental restoration system allows it to be custom designed for the system.

[0041] Therefore, the gingival former preferably has an attachment structure corresponding to the fixing structure of the locking member. For example, the attachment structure can be embodied as a socket having an internal thread, and the fixing structure of the locking member can be embodied as a corresponding post having an external thread. In this way, the locking member can be efficiently connected to the gingival former.

[0042] In another aspect, the invention is a method for constructing a restoration on an implant structure placed in a patient's jaw, the method comprising the steps of attaching a gingival former to the implant structure, placing a crown abutment on the gingival former, the crown abutment having a through hole configured to receive a locking member such that a contact surface of the locking member contacts the crown abutment and the locking member's locking structure extends at least partially from the crown abutment to the gingival former, and disposing a pin in the through hole of the crown abutment, the pin having a locking structure corresponding to the locking member's locking structure, such that the pin extends through the through hole of the crown abutment, the locking structure of the pin engages the gingival former, and the pin engages the crown abutment. the crown abutment so as to protrude above the abutment, constructing the crown with crown material that bonds to the crown abutment but not to the pin so as to form a monolithic crown including the crown abutment, removing the pin so that a through-hole is provided in the crown, and securing the crown to the gingival former with a locking member having a contact surface and a fastening structure configured to be secured to the gingival former, the locking member being received in the through-hole of the crown abutment such that the contact surface of the locking member contacts the crown abutment and the fastening structure engages with the gingival former. The restoration may in particular be a temporary restoration.

[0043] The method according to the invention and the preferred embodiments thereof described below make it possible to carry out and achieve the effects and advantages set out above in relation to the dental restoration system according to the invention and the preferred embodiments thereof described above.

[0044] Preferably, the locking member has a breakaway structure configured to break at a predetermined threshold load applied to the crown when the locking member secures the crown to the gingival former.

[0045] Preferably, the crown is constructed with smaller dimensions than the tooth it temporarily replaces. This smaller crown reduces the loads or forces acting on the crown during use, thereby reducing mechanical stress on the implant structure during healing. In particular, the crown can be reduced in size to a degree that allows chewing without substantial restriction, yet sufficiently reduces the loads or stresses applied.

[0046] The dental restoration system according to the invention and the method for building a restoration on an implant structure according to the invention are explained in more detail below by way of exemplary embodiments with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0048] In the following description, certain terminology is used for convenience and is not intended to limit the invention. The terms "right," "left," "up," "down," "under," and "above" refer to directions in the figures. The terminology consists of explicitly mentioned terms, their derivatives, and terms of similar meaning. In addition, spatially relative terms such as "beneath," "below," "lower," "above," "upper," "proximal," and "distal" may be used to describe the relationship of one element or feature to another, as illustrated in the figures. These spatially relative terms are intended to encompass various positions and orientations of the device during use or operation in addition to the position and orientation depicted in the figures. For example, if a device in the figures were turned over, elements described as "below" or "beneath" other elements or features would be "above" or "over" them. Thus, the exemplary term "below" can encompass both above and below positions and orientations. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein are interpreted accordingly. Similarly, descriptions of movement along and about various axes include various particular device positions and orientations.

[0049] To avoid repetition in the figures and descriptions of various aspects and exemplary embodiments, it should be understood that many features are common to many aspects and embodiments. The omission of an aspect from a description or figure does not imply that the aspect is absent from an embodiment incorporating that aspect. Instead, the aspect may be omitted for clarity and to avoid redundant description. In this context, the following applies to the remainder of this description: For clarity of the drawings, if a figure contains a reference sign that is not described in the directly relevant part of the description, reference is made to a previous or subsequent description section. Furthermore, for clarity, if not all features of a part are labeled with a reference sign in a drawing, reference is made to other drawings showing the same part. Like numbers in two or more figures represent the same or similar elements.

[0050] FIG. 1 shows an exploded view of an embodiment of a dental restoration system 1 for restoring a tooth during healing of an implant 5 placed in a patient's jaw. The dental restoration system 1 includes a healing abutment 4 as a gingival former, a temporary crown abutment 3, and a crown screw 2 as a locking member. The healing abutment 4 is formed with an emergence profile 43 for conditioning or shaping the gingival soft tissue. More specifically, the emergence profile 43 of the gingival former is configured to prepare and shape the gingiva during healing into the jaw after the implant 5 has been placed in the jaw. The healing abutment 4 is attached to the implant 5, which is shown schematically in the figure as a block.

[0051] At its apex or occlusal end, the healing abutment 4 has a flat abutment platform 42 for supporting the body 32 of the temporary crown abutment 3. An indexing knob 41 projects occlusally or superiorly from the abutment platform 42. The indexing knob 41 is configured to define the orientation and position of the crown abutment 3 when attached to the healing abutment 4, as described in more detail below.

[0052] The crown screw 2 has, from the top down, a screw head 21, a break post 22 as a weakened section of the break structure, a hexagonal head 23 as an auxiliary tool shape, and a threaded portion 24 as a fixing structure. The break post 22 is shaped as a cylinder with a reduced diameter compared to the rest of the crown screw 2. The break post 22 is located between the screw head 21 and the hexagonal head 23. By having a reduced diameter, the break post 22 has a reduced resistance to loads or forces applied to the crown screw 2. Therefore, the break post 22 defines the maximum load or threshold that the crown screw 2 can withstand. When the crown screw 2 is subjected to a load exceeding the threshold, the break post 22 breaks. This exposes the hexagonal head 23 so that it can be accessed by a hexagonal screw tool. The threaded portion 24 is embodied as a cylinder with a larger diameter than the break post 22. The cylindrical outer periphery of the threaded portion 24 is provided with an external thread.

[0053] 2 shows the dental restoration system 1 with the crown abutment 3 placed on the healing abutment 4 so that its flat lower end abuts against the abutment platform 42 of the healing abutment 4. The indexing knob 41, together with the corresponding cavity in the crown abutment 3, thereby ensures accurate positioning of the crown abutment 3 on the abutment platform 42 and accurate rotational orientation of the crown abutment 3 relative to the healing abutment 4 and implant 5.

[0054] Figure 3 shows a cross-sectional view of the dental restoration system 1 in its assembled state. It can be seen that the gingival former 3 is secured to the implant 5 by an implant screw 7 having a top head with a cone 71 that applies lower pressure and a bottom threaded portion 72. The implant 5 has a central vertical blind hole with a gingival former socket section 51 at the top and a screw socket section 52 at the bottom. The healing abutment 4 seats in the blind hole of the implant 5 so that the bottom end of the healing abutment 4 rests in the gingival former socket section 51 of the implant 5.

[0055] The healing abutment 4 has a vertical central bore 44 that extends through the complete healing abutment 4 and includes a pressure cone 411. The implant screw 7 is placed within the healing abutment 4 such that the head is located inside the bore 44 and the threaded portion 72 extends outside the healing abutment 4. More specifically, the implant screw 7 is threaded into a blind hole in the implant 5, with the threaded portion 72 engaging the screw socket section 52. This forces the pressure cone 71 of the implant screw 7 against the pressure section 411 of the healing abutment 4, firmly securing the healing abutment 4 to the implant 5.

[0056] The crown abutment 3 has a through hole 31 configured to receive the locking screw 2. The locking screw 2 is disposed within the through hole 31 such that the bottom surface 211 of its head 21 abuts the crown abutment 3, thereby forming a contact surface. A threaded portion 24 protrudes downward from the crown abutment 3 and extends into a bore 44 of the healing abutment 4. More specifically, the threaded portion 24 engages with corresponding internal threads formed in the bore 44. This presses the bottom surface 211 of the head 21 against the crown abutment 3, securely securing the crown abutment 3 to the healing abutment 4. A crown 6 is formed on the crown abutment 3 according to an embodiment of the method of the present invention as follows.

[0057] The healing abutment 4 is attached to the implant 5, and the crown abutment 3 is placed on the healing abutment 4 as described above. However, as shown in Figures 4 to 6, before the locking screw 2 is inserted, the through hole 31 of the crown abutment 3 is provided with a pin 102 having a fixing structure 124 corresponding to the threaded portion 24 of the locking screw 2, which extends through the through hole 31 and engages with the healing abutment 4. This causes the pin 102 to protrude onto the crown abutment 2.

[0058] A resin-based composite is then obtained as the crown material. The crown abutment 3 is made of an abutment material configured to bond with the resin-based composite material, while the pin 102 is made of a pin material configured not to bond with the resin-based composite material.

[0059] The crown 6 is formed according to the natural tooth to be restored by building up the composite material layer by layer on the crown abutment 3. This bonds the crown material with the composite material so that the crown abutment 3 and crown 6 are monolithically formed as a single piece. Compared to the natural tooth to be restored, the crown 6 is slightly smaller.

[0060] After building the crown 6 , the pin 102 is removed from the healing abutment 4 so that a through-hole is provided in the crown 6 that allows access to the through-hole 31 in the crown abutment 3 .

[0061] 4 and 5 show a pin 102 positioned within the through-hole 31 of the crown abutment 31, which is installed on the healing abutment 4. The pin 102 has a rod element 104 extending through the through-hole 31. The rod element 104 functions as a placeholder or mold for forming the through-hole in the crown 6 so that a continuous through-hole is established through the crown 6, the crown abutment 3, and the healing abutment 4. The pin 102 further has a handle 103 that can be used to mount and adjust the position and orientation of the pin 102, thereby facilitating placement of the pin 102 and increasing precision when forming the through-hole.

[0062] 6 shows that the pin 102 has a fixing structure 124 that is the same shape as the threaded portion 24 of the locking screw 2. After the through hole is formed, the pin 102 is removed. Because the pin 102 is made of a pin material that does not bond with the crown material, no residue is left when the pin 102 is removed, and a through hole of the appropriate size and orientation is created in the crown 6. Therefore, the through hole in the crown 6 can be formed with a relatively high degree of precision.
