[0002] DENTAL IMPLANT SYSTEM

[0003] Corresponding application

[0004] The present application claims priority to the earlier international patent application N° PCT / IB2025 / 050830, filed on January 24, 2025, in the name of SEVEN SOULS CONSULTING LLC, INSIGHTFUL CONSULTANTS LLC and ONE IDEA DEVELOPMENTS LLC, the content of this earlier application being incorporated by reference in its entirety in the present application.

[0005] Field of the Invention

[0006] The present invention relates to dental implantology and guided bone regeneration, specifically addressing the challenges associated with the rehabilitation of atrophic maxilla and mandible, particularly in cases characterized by significant bone loss.

[0007] More precisely, the present invention pertains to the field of implant biomechanics and decoupled stabilization systems. It tackles the challenge of supra-critical micromovement and cellular trauma in compromised bone, enabling the completion of both reconstruction and rehabilitation processes in a single surgical stage, even in cases of significant bone loss. The system incorporates a supplementary locking mechanism that restricts micromovement across all six degrees of freedom of the device, regardless of the initial bone density.

[0008] Prior Art

[0009] Dental implants have gained widespread acceptance as an effective solution for replacing missing teeth. Typically resembling screws, they can be cylindrical or conical and are surgically implanted into the jawbone of a patient to restore both functionality and aesthetics. The success of dental implant treatments relies heavily on achieving primary stability, which refers to the initial resistance to micromovement between the implant and the surrounding bone immediately after placement.

[0010] A dental implant according to the state of the art is shown in Figure 1. Typically, such a system comprises the implant 1 which is fixed in a jawbone 2 and a prosthetic screw 5 which is used to fix an abutment 3 to the implant 1. The abutment 3 carries a crown 4 which forms the replacement tooth. In the procedure, the implant 1 is first screwed in the jawbone 2 and leftP4300PC00 / 1327-003 spec dpt

[0011] in place a certain time (several weeks for example) until it is properly integrated in the jawbone 2. Then the abutment 3 is mounted on the implant 1 and attached thereto with the prosthetic screw 5. Finally, the crown 4 is mounted on the abutment 3.

[0012] The current state of the art predominantly depends on friction and lateral bone compression (press-fit adjustment or "Press-Fit") to achieve primary stability. In many cases, particularly in low-density or atrophic bone, attaining adequate stability requires elevated insertion torque or aggressive under-drilling, which can carry a risk of compressive ischemia or necrosis (a potential "biological toll").

[0013] In atrophic bone, this dependency can make it more challenging to achieve reliable stability without additional measures, potentially compromising vascular viability in certain conditions.

[0014] Therefore, guided bone regeneration in severe cases sometimes requires a two-stage protocol to ensure the stability of both the graft and the implant, which prolongs the treatment and may increase morbidity and risks for the patient. Consequently, there exists a need for a system that achieves enhanced mechanical stability while minimizing radial bone compression in challenging scenarios, thereby reducing the potential for ischemia and improving vascular perfusion where compression-related risks are higher.

[0015] A considerable number of patients, particularly older individuals, show an atrophic maxilla or mandible, characterized by an alveolar bone deficit. Such patients pose significant challenges in achieving adequate primary stability due to diminished bone volume and density. Current approaches can achieve good results in many cases but often require multiple surgeries and complex bone augmentation procedures in severe atrophy, leading to extended treatment time and increased patient discomfort.

[0016] Summary of the Invention

[0017] An aim of the present invention is to improve known dental implants, implant systems, kits and parts thereof, particularly to overcome the challenges of reconstructing and rehabilitating the atrophic maxilla or mandible with alveolar bone deficit, in a simple, reliable, safe andP4300PC00 / 1327-003 spec dpt

[0018] stable manner, while offering advantages in cases where conventional press-fit mechanics may present higher biological risks.

[0019] In some non-limiting embodiments, the present invention concerns a dental implant system that simplifies and streamlines the reconstruction and rehabilitation processes, in particular for atrophic maxilla and mandible, by enabling reliable single-stage treatment (bone augmentation and implant placement simultaneously) in cases where traditional methods carry greater risks of micromovement or compressive complications.

[0020] To overcome the aforementioned challenges, the present invention introduces a biomechanical paradigm shift.

[0021] The system includes a bone site preparation protocol characterized by the creation of a congruent receptor geometry. Unlike conventional approaches, the invention incorporates optional pre-tapping means (in a preferred embodiment, a calibrated bone tap). The use of these means, when applied, ensures that implant insertion generates minimal and controlled radial compression, allowing a sub-necrotic insertion torque that preserves immediate vascularization in situations where compression is a concern.

[0022] Primary stability does not depend solely on friction from the implant body but is achieved primarily through activation of the supplementary anchoring element. This element is configured to generate an active pre-load that induces an interference fit between the screw, the implant, and the bone. This results in rigid locking through controlled compressive forces at the interfaces, eliminating micromovements.

[0023] Additionally, the system is defined as an integral stabilization unit ("Sandwich Effect"), where the transverse element simultaneously locks both the implant and the regenerative complex (cortical plates, membranes, meshes, bone blocks, etc.) against the basal bone, with the implant acting as a structural pillar ("tent-pole effect") to maintain graft volume and prevent soft tissue collapse.P4300PC00 / 1327-003 spec dpt

[0024] It is important to highlight that the claimed procedure is characterized by differentiated functional stability: A) In dense bone, the bone tap can be used to eliminate potential ischemic compression. B) In soft bone or defects, pre-tapping is omitted or under-drilling is performed to achieve "operative tactile stability," sufficient to immobilize the drilling guide 40, without relying on such friction for long-term retention.

[0025] The final stability (Figures 10A-10B) is then provided by the active pre-load of the primary screw 20, creating the interference fit independently of the initial bone density.

[0026] In addition to the stepped drill 50 and the drilling guide 40, the surgical kit comprises a set of instruments configured for an adaptive insertion protocol. This set includes a bone tap calibrated to the geometry of the implant 10. The inclusion of this instrument allows the clinician to modulate the insertion according to bone quality: in high densities (Type l / l I ), the bone tap is used to create a passive pathway (sub-necrotic torque); in low densities (Type 111 / IV), the system permits direct insertion (without bone tap) to generate the controlled friction necessary for positional stability of the guide.

[0027] While the transverse anchoring system introduces additional surgical steps and considerations (such as precise guided placement to minimize risks of anatomical structure involvement), these are mitigated by the dedicated drilling guide and self-tapping features.

[0028] Description of Embodiments

[0029] Embodiments of the present invention concern inter alia a dental implant 10 comprising a body, having a proximal portion configured for enabling a prosthesis (for example an abutment and a crown) to be fixed thereto and a distal portion containing at least one transverse apical channel 11 configured for receiving and holding a supplementary anchoring element that extends along a transverse direction with respect to the implant body main axis.

[0030] The implant 10 may comprise external threading (or not, or partially) compatible with the calibrated bone tap and sufficient to provide operative tactile stability before placement of the supplementary anchoring element.P4300PC00 / 1327-003 spec dpt

[0031] The implant 10 is preferably constructed from titanium, zirconia, or other implantable materials and is specially designed to enhance primary stability primarily through the supplementary anchoring element, particularly in compromised bone.

[0032] In embodiments, the transverse apical channel 11 forms a through-channel or blind channel and may be oblique (its axis not perpendicular to the implant's axis). The channel 11 may comprise an inner thread cooperating with the supplementary anchoring element and / or a conical section designed to facilitate self-positioning of the element.

[0033] Preferably, the supplementary anchoring element comprises a primary screw 20 with selftapping thread and a secondary screw 30 screwed into the primary screw 20. The secondary screw 30 may have a sharp apex 33 to perforate membranes.

[0034] Materials for the supplementary anchoring element may be non-resorbable (titanium, zirconia, etc.) or resorbable (magnesium alloys, polymers, etc.).

[0035] More generally, the implant and the supplementary anchoring element may be made in known suitable materials: metals, mix thereof, and alloys thereof, zirconia (ZrO2), alumina (AI2O3), mix thereof, titanium, alloys thereof etc.

[0036] The supplementary anchoring element reinforces the implant's stability, particularly in situations where the intrinsic design of the implant thread alone may not provide sufficient support, for example in case of bone loss as explained above.

[0037] Advantageously and in embodiments, a dedicated drilling guide is integrated into the system to facilitate precise drilling at the correct bone location for optimal placement of the supplementary anchoring element. This drilling guide is preferably mounted on the implant, which forms a reference. Preferably, the drilling guide is not fixed only on the implant to avoid mechanical constraints or stress on the implant itself. To this effect, additional means are used as described herein. The implant, the supplementary anchoring element and the drilling guide may form a kit with said different parts. In certain embodiments, the drilling guide is modular and fully adjustable in length (similar to telescopic trekking poles). This design allows it to beP4300PC00 / 1327-003 spec dpt

[0099] Figures 2A 2B, 3A and 3B illustrate an embodiment of an implant 10 according to the present invention. The implant 10 comprises a transversal apical hole 11 (for example under the shape of a channel) at its distal end which, in the implantation procedure, will receive a supplementary anchoring element 20, for example in the shape of a primary screw 20, as illustrated in figures 3A and 3B. Figures 3A (perspective view) and 3B (side section view) show the implant 10 and the supplementary anchoring element 20 in their non-assembled state, i.e. before they have been implanted in the bone of a patient as will be explained and illustrated in the following description. The implant 10 also comprises an inner thread 13 (see figure 2B) to receive a prosthetic screw 5 (see figure 1) for example, and an outer thread 12.

[0100] As illustrated in figures 2A and 2B, the hole / channel 11 comprises an inner thread for cooperation with the outer thread 21 of the supplementary anchoring element 20, and a conical section 14 cooperating with a conical section 26 of the supplementary anchoring element 20 (see figure 3B) to provide a self-positioning of the supplementary anchoring element 20 when mounted (see figure 10A to 10D).

Specifically, the drilling guide 40 is mounted on the implant 10 with an occlusal screw 41 being attached to an inner thread 13 of the implant 10, the inner thread 13 being used at the end of the procedure to attach an abutment 3, via the prosthetic screw 5 (see figure 1), on which the crown 4 will be mounted. The drilling guide 40 is attached for example by rotating handle 41. To stabilize the guide 40 and to hold the cortical plate 70 during the transversal drilling of the jawbone 60, two stabilization pins 42 are preferably used so (which pins may be moved axially by screwing or unscrewing) that the guide 40 is not fixed only by the implant 10. The drilling guide 40, once in place and indexed by its attachment to the implant 10 allows to define a reference to drill the jawbone 60 through channel 43.P4300PC00 / 1327-003 spec dpt

[0111] As illustrated in figures 10A to 10D, the implant 10 is now stable and will be ready, after typically a couple of months, to receive the abutment 3 and a crown 4 as is done in the art of the invention (see figure 1). The implant 10 is stabilized by the supplementary anchoring element 20 which compensates the bone deficit in zone 61.

[0112] In some embodiments, the implant system according to the present invention is used to carry out a bone augmentation procedure as illustrated in the figures discussed hereunder.

[0114] More specifically, figures 11A and 11B illustrate an embodiment where bone substitute 90 has been added between the plate 70 and the jawbone 60 whereby the plate 70 ensures that the bone substitute 90 remains in place.P4300PC00 / 1327-003 spec dpt

[0115] Figure 12A (perspective view) and 12B (side partial cut view) illustrate an embodiment in which a membrane 100 is used to protect and hold together the bone substitute 90 and the cortical plate 70 during the healing phase. As mentioned above, the membrane 100 may be a resorbable membrane, such as those made of collagen, magnesium, or any membrane fulfilling this function, or a non-resorbable membrane 100, such as expanded polytetrafluoroethylene reinforced with titanium. The membrane is preferably pierced by the distal end 33 of the secondary screw 30 and this screw is used to hold the membrane 100 in position. To this effect, the secondary screw 30 is screwed in the primary screw 20.

[0116] The dental implant system presented herein offers several distinct advantages over existing solutions, particularly in severe atrophic cases. By enabling reliable reconstruction and rehabilitation of atrophic maxilla and mandible in a single surgical stage in appropriate indications, it can reduce treatment time and patient discomfort compared to staged approaches. The utilization of the transverse apical channel 11, the incorporation of the supplementary anchoring element (primary screw 20 and secondary screw 30), and the inclusion of the dedicated drilling guide 40 ensure enhanced implant primary stability and precise surgical placement while minimizing radial compression risks. Furthermore, in embodiments where the supplementary anchoring element is either resorbable or optionally removed after initial osseointegration, the transverse apical channel 11 permits bone ingrowth. This biological anchoring within the channel provides additional long-term stability to the implant system, complementing the primary osseointegration along the implant body. Additionally, the optional utilization of bone substitute material 90 promotes bone regeneration and facilitates successful implant integration.
