Description

[0001] DESCRIPTION

[0002] "Optimized dental implantology system"

[0003] The present invention relates to an optimized dental implantology system.

[0004] In particular, the present invention relates to an optimized dental implantology system, of the type used in dentistry .

[0005] As is known, dental implantology refers to that set of surgical techniques aimed at functionally rehabilitating a patient suffering from total or partial edentulism through the use of dental implants, or devices surgically inserted into the mandibular or maxillary bone, aimed at allowing the connection of prostheses, fixed or mobile, to restore masticatory function. These implants can be of different shapes, inserted in different locations with different techniques and then connected to the prostheses with different timing.

[0006] Currently, implant-supported therapeutic solutions are highly predictable for replacing compromised or missing teeth. To guarantee implant osseointegration, initially 3 to 12 months of healing of the post-extraction socket were expected. Numerous scientific research in this technical field has aimed at optimi zing the timing of implant positioning .

[0007] In a single implant in the aesthetic area, the implant positioning in healed site leads to dimensional alterations of the bone crest and atrophy, the indication falls on implant positioning in the shortest possible time after tooth extraction . Structural and dimensional changes of the postextraction bone crest are in the buccal-lingual / palatal and apico-coronal direction of the buccal bone part and bundle bone , observed in experiments conducted on dogs and humans .

[0008] Morphology, structure and health of the soft tissues are essential to preserve to ensure a correct aesthetic outcome of an implantology treatment .

[0009] It is important to have an adequate three-dimensional bone volume of the alveolar crest and possibly carry out bone augmentation procedures to promote excellent aesthetics without defects in the post-extraction site .

[0010] Alveolar preservation techniques and immediate implant placement , positioned in the post-extraction socket immediately at the extraction site without waiting for the bone and soft tissues to heal , do not prevent the physiological remodelling of the bone after extraction .

[0011] The portion of the peri-implant mucosa, the mucosal seal , which faces the implant abutment is made up of a coronal part made up of j unctional epithelium and sulcular epithelium ( 1 . 5 -2 mm according to experimental studies on animals ) and an apical portion which appears in direct contact with the implant surface ( 1 - 1 . 5 mm according to experimental studies on animals ) . The process of formation of the peri-implant mucosa on implants positioned in postextraction sockets is described by Vignoletti in a study conducted on dogs . It is observed that at 1 week the j unctional epithelium is continuous with the oral epithelium, the connective tissue is rich in inflammatory cells . At 4- 8 weeks there are no longer signs of inflammation, the epithelial barrier is mature in close contact with the titanium, the connective tissue rich in fibroblasts appears dense .

[0012] Compared to a study, also conducted on dogs by Berglundh on implants positioned in healed ridges , in Vignoletti ' s study the epithelial barrier in post-extraction implants remains wider during healing .

[0013] Abrahamsson et al . in a study conducted on dogs evaluates the ef fect of repeated disconnections and reconnections of the abutment on the peri-implant tissues . The results demonstrate that the frequent reconnections of the abutment to the implant surface result in a more apical positioning of the connective tissue and in a loss of marginal bone (marginal bone loss) to try to establish a correct biological width of the peri-implant seal. Abutments made of titanium allow the formation of a mucosal attachment of epithelial tissue and connective tissue. The limits and therefore the current objectives of the implant-prosthetic sector, especially in the anterior aesthetic area, are stability over time, respect for the tissues, less postoperative discomfort, and immediate provisionalization .

[0014] The needs of the patients, and therefore the aim of current studies, is to have implants and techniques that allow treatments with a lower number of surgeries, reduced number of visits, reduced times, reduced costs, preservation of the bone at the level of the implant site, optimal soft tissue aesthetics.

[0015] Also, systems described in documents WO2018 / 234247A1 and US2012 / 295223A1 are known. These known systems, however, do not solve the technical problem of providing customization and optimization of a dental implant based on the specific tooth and the arch considered, such as to maximize osseointegration and which is dimensionally optimized.

[0016] The Applicant, during previous research and studies, has described an implant system in the Italian patent no. 102019000025480 . However, the dental implant system already described is not perfectly customi zed based on stati stical and mathematical analyses , or optimized based on the speci fic tooth and arch considered, nor does it allow it to be applied to multiple or inclined implants .

[0017] Scope of the present invention is to provide an optimi zed implantology system, i . e . a system that maximi zes osseointegration and which is dimensionally optimi zed and standardised . Finally, the scope of the present invention is to provide an optimi zed dental implantology system able of providing an implant-pillar-healing cap connection which allows the insertion of customi zed definitive titanium pillars , inserted during a surgical procedure and no longer removed from the implant interface , in such a way as to prevent the detachment of the abutment and overcome the limitations presented by the systems known so far .

[0018] The dental implantology system according to the present invention allows a surgical and prosthetic procedure to be carried out at the same time , at the so-called time 0 . Currently, however, a surgical act is carried out first which has the aim of integrating the implant and, at a later time , it is a prosthetic intervention has been carried out , with a healing pillar or a temporary one , which tends to shape both the bone tissue and the mucosal tissue . According to the present invention, a dental implantology system is disclosed, as defined in claim 1 .

[0019] For a better understanding of the present invention, a preferred embodiment is now described, purely by way of nonlimiting example , with reference to the attached drawings , in which : figure 1 shows some components of the dental implantology system according to the invention; figure 2 shows views of a cap of the dental implantology system, and in particular of an incisor cap, according to the invention; figure 3 shows views of a cap of the dental implantology system, and in particular of a cap for grinding, according to the invention; figure 4 shows views of a cap of the dental implantology system, and in particular of a premolar cap, according to the invention;

[0020] - figure 5 shows views of an abutment of the dental implantology system, and in particular of an incisor abutment , according to the invention;

[0021] - figure 6 shows views respectively of a coping and a provisional for angled implants , according to the invention . With reference to these figures , a component of the optimi zed dental implantology system is shown, according to the invention .

[0022] In more detail , the optimi zed dental implantology system which is the obj ect of the present invention comprises :

[0023] - at least one pillar customi zed in titanium suitable to be placed on the dental implant , the shape of the pillar being such as to follow the natural contour of a speci fic tooth in the root crown interface at the level of the CEJ;

[0024] - at least one healing cap in PMMA or PEEK, with locking taper, having a flared lower portion and such as to be inserted and fitted perfectly on the pillar, the flaring being suitable for shaping the j oint connection;

[0025] - at least one capsule , or a provisional crown, fixable to the pillar by means of the cap, made of PEEK or PMA; characteri zed in that the pillar consists of :

[0026] - a first sub-gingival portion thereof , which extends in height by about 2 mm - 4 mm from the internal connection on the implant head, having a vestibular surface , a mesial surface , a distal surface , and a palatal surface , adapted to mature the connective attachment and the j unctional attachment , the f laring of the surfaces of the pillar in the first sub-gingival portion being in turn divided into two parts , a first part adapted to be brought into contact with the implant and, in use , to protect the clot which in turn is trans formed into bone in the portion in contact with the implant , and into connective tissue in the portion in contact with the first part of the flared pillar, and a second part on which the cap is fitted, adapted to mature the j unctional attachment , and

[0027] - a second supragingival portion whose height is adapted to the masticatory height of a patient , and between 5 mm and 7 mm, and a di f ferent flare , or di f ferent inclination with respect to the vertical , on which the customi zed cap is adapted in a first phase of healing that assists together with the provisional crown to model the j unctional attachment and the crevicular sulcus ( sulcular epithelium) , cap and provisional crown being replaced at maturation of the hard and soft tissues by the definitive structure .

[0028] The pillar shape comprises a vestibular switch, a mesial switch, a palatal switch and a distal switch, each variable on the vestibular (V) , palatal ( P ) , mesial (M) and distal ( D) surfaces and variable from tooth to tooth .

[0029] According to an aspect of the invention, the system consists of :

[0030] -at least one dental implant ; - at least one customi zed abutment 101a, 101b, 101c . . . l O ln, in titanium, suitable for being placed on the dental implant , the shape of the abutment being such as to follow the natural contour of a speci fic tooth in the crown-root interface at the level of the CEJ ( cement-cement j unction) ;

[0031] - at least one healing cap 102a, 102b, 102c, . . . 102n ( in PMMA or PEEK) fixable to the implant , with a conometric connection, having a flared lower portion and such as to be inserted and fitted perfectly on the pillar, the flare being suitable for model the j unctional attachment ; - at least one capsule 103a fixable to the definitive pillar, or temporary fixable to the cap which in turn can be fixed to the pillar and preferably made of PEEK or PMA.

[0032] According to one aspect of the invention, the pillar is made up of : its first sub-gingival portion, which extends in height for approximately 2 mm - 4 mm from the internal connection on the implant head, having a vestibular surface, a mesial surface , a distal surface , and a palatal surface , suitable for maturing the connective attachment and the j unctional attachment , the flaring of the surfaces of the pillar in the first sub-gingival portion being in turn divided into two parts , a first part designed to be placed in contact with the implant and, in use , to protect the clot which in turn transforms into bone in the portion in contact with the implant , and into connective tissue in the portion in contact with the first part of the flared pillar, and a second part on which the cap fits , designed to allow the maturation of the j unctional attachment , and

[0033] - a second supragingival portion whose height is adapted to the masticatory height of a patient , and is between 5 mm and 7 mm, and a di f ferent flare , or di f ferent inclination with respect to the vertical , on which the customi zed cap adapts in a first phase of healing which helps together with the provisional to model the j unctional attachment and the crevicular sulcus ( sulcular epithelium) , the cap and provisional being replaced once the hard and soft tissues have matured by the definitive structure .

[0034] Therefore , the flaring of the surfaces of the pillar in the subgingival portion is suitable , in use , to protect the clot which in turn trans forms into bone , in the portion in contact with the implant , and into connective tissue , in the portion in contact with the first part of the flared pillar, said pillar also including a second part on which the cap is fitted in use , suitable for curing, in a portion of it which extends in height for approximately 2 mm - 4 mm from the j unctional attachment .

[0035] A mucous seal consists of : 1) super critical area: near bone crest 1 mm above the implant: connective adhesion;

[0036] 2) critical area: junctional adhesion determined by the cap: flared below, in continuity with the shape of the post in contact with the implant head, and flared above to accommodate a temporary, which adhesively connects to the cap and shapes the crevicular sulcus or sulcus gingival non- critical area.

[0037] Figure 1 shows an example of the morphology of dental implantology system components. However, each component is optimized and customized, as described below.

[0038] The abutment 101a, 101b, 101c, ...lOln and the healing cap 102a, 102b, 102c, ... 102n have an optimized shape and size such as to protect the underlying clot and allow its differentiation into the different tissues, connective tissue, junctional epithelium and crevicular epithelium .The inclined or flared surfaces of the abutment 101a and the cap 102a, 102b, 102c, . . . 102n are uniform and continuous at their junction and allow different tissues to mature in a safe and protected way.

[0039] Each abutment 101a results from a statistical and mathematical analysis, and having an optimized shape that follows the natural contour of the tooth in the crown-root interface at the level of the CEJ, i.e. the cement-cement j unction .

[0040] The abutment according to the invention, with or without regenerative techniques, allows the stabilization of the clot at zero time, which in the interface with the abutment can differentiate and mature without being altered.

[0041] At time 0, i.e. with the first surgery, the system according to the invention allows you to try the definitive structure and finalize the implant insertion with the affixing of a cap 102a, 102b, 102c, . . . 102n customized with a conometric connection which guarantees the modelling of the profile of the peri-implant mucosa, maintains the volume of the soft tissues and guarantees further protection to the clot. The conometric connection guarantees stability and minimal bacterial inf iltration . The post and the cap are customized in the sense that the right, left, upper and lower quadrants are not identical but are differentiated in shape, inclination of the surfaces and height depending on the position in which to perform the implant, i.e. where it is located in the dental arch the tooth to be replaced by implant .

[0042] Advantageously, customization allows to adapt the system in a specific and optimized way. In particular, the abutment is not drawn on the impression, but is created in an optimi zed and universal way based on statistical morphological evaluations , advantageously al lowing the implant , definitive abutment and temporary cap to be placed in a single operation with evident positive repercussions .

[0043] As shown in the figures , the pillar 101a has a variable diameter and lateral surfaces having di f ferent inclination and height depending on whether the distal , mesial , palatial or vestibular surface is considered .

[0044] Furthermore , the abutment 101a has an adapted and optimi zed height in its supra-gingival portion based on the masticatory height of a patient , between 5 mm and 7 mm .

[0045] The pillar 101a according to the present invention can have a greater or lesser height depending on the interocclusal space , being respectively equal to 7 mm, and 5 mm or 6 mm .

[0046] This characteristic of the pillar 101a advantageously resolves prosthetic problems linked to the variation of the vertical dimension of occlusion . Furthermore , i f there is a change in the inclination between the implant and the pillar, there is a risk that the connection between the pillar and the implant will be altered . In these cases the pillar according to the invention can include a dynamic or angled screw which allows to compensate for an angular di f ference between 15 and 20 degrees .

[0047] In the case of a multiple implant and i f the angulation exceeds 15-20 degrees , the system according to the invention can use either a customi zed abutment in the molar or premolar area, or in the aesthetic area, or an angled abutment available on the market and on it apply a customi zed coping .

[0048] The system also allows you to correct any incorrect implant insertions , through the use of the customi zed cap 102a, 102b, 102c, . . . 102n .

[0049] Furthermore , advantageously, the temporary fixed over the cap, in addition to adapting by compensating for the di f ferent inclination, causes the cementation image to move away from the bone crest , because the cap and temporary work on the critical area j unctional attachment while the super critical area where the connective tissue adhesion is formed and is protected by the lower portion of the customi zed pillar . The morphology of the cap therefore allows for optimal protection of the clot . The system according to the invention also allows surgical problems to be solved . The mucous seal is divided into three areas and the system according to the invention is optimi zed and acts on all three areas . In the super critical upper area, in contact with the bone crest , the abutment is advantageous as it is mounted in zero time and has customized morphology, typical of the tooth that is replaced and is no longer removed, protecting the mucous seal (connective adhesion) . In the sub-critical area the cap continues the shape of the pillar, further protecting the clot, helps differentiation and also guides the mucous seal to acquire the optimized shape, in the 2-3 mm that concern: junctional adhesion. In the third area, of the sulcular epithelium, the provisional allows, by joining the cap, to give the curvature and complete the morphology of the maturation of the tissues at the marginal level, adapting to the morphology of the natural tooth that has been replaced, respecting the anatomical and biological characteristics of the patient. The temporary is also customized and is applied to the cap at zero time, or after three months, assisting and supporting the mucosa by giving it the suitable morphology.

[0050] The currently known systems apply a provisional after a direct analog impression after surgery, or indirect after 6 months, modifying the provisional to adapt its shape, compressing the tissues of the gingival margin.

[0051] Furthermore, an upper portion of the post appears to have a flare exactly corresponding to a lower flared portion of the healing cap. As shown in figures 2-4, each coping 102a, 102b, 102c, ... 102n, although specific and customized, has similar structural and morphological characteristics . Each cap has a flare at one of its base ends , such as to obtain the advantages already described, an intermediate portion of diameter DI and a final portion of diameter D2 in which D2<D1 . The final portion has inclined surfaces , of approximately 7 degrees , generally not parallel to each other, which allows conometric adhesion, and is perforated at the top . The PMMA cap connects to the titanium pillar in a conometric way and is divided into two parts : the first continues the des ign of the pillar which is di f ferent on the four surfaces (M; D; V; L ; ) up to the gingival margin, the second which develops beyond the margin, or below the margin by 1 mm, has an internal counter switch which accommodates the provisional which is modi fied and adapted to the sulcular margin, guiding its maturation and shape in a customi zed manner .

[0052] Advantageously, the system helps promote healing and protection of the clot as well as modelling the epithelial tissue . Furthermore, it allows you to build a temporary one and take a digital impression for the definitive one , to determine the morphology of the soft tissues and consequently define the aesthetics of the definitive capsule which will be screwed or superimposed in conometric mode . The shape of the pillar and the healing cap has differentiated and optimized profiles and curvatures depending on the upper or lower location, right or left, in the aesthetic or non-aesthetic area. Each profile is obtained from a statistical and morphological study which allows us to obtain a system designed specifically based on the tooth to be replaced (in the paracrestal portion in that part of the tooth called the cementum junction, and not on the individual patient.

[0053] Advantageously, the temporary, the definitive crown with or without aesthetic material, are customized and in harmony with the morphology of the patient's other teeth.

[0054] As mentioned above, the system can be created in alternative forms, described below, specific based on the tooth in question that is intended to be replaced by the dental implant system.

[0055] The shape of the abutment, in particular, includes a different 'switch' from tooth to tooth and for each of them it varies on the different surfaces: vestibular, palatal, mesial and distal. The V-M-P-D switch will have different heights and in particular: 2.5 mm Vestibular, 3.5 mm Mesial, 3 mm Palatal, between 2.5 mm and 3 mm Distal, preferably equal to 3 mm, when considering a tooth in an anterior position. The switch is different in a mirrored way by referring to the right or left side of the upper or lower arches . The pillar according to the invention instead includes a Vestibular switch (V) which has a height equal to 1 . 5 mm, the Mesial one (M) has a height equal to 2 . 5 mm, the Palatal one ( P ) has a height equal to 2 mm, the Distal one ( D) has a height of 2 mm, when considering a tooth in a posterior position with respect to the entire dental arch .

[0056] Advantageously, the speci fic shape of the system al lows you to protect the clot and promote its trans formation into di f ferentiating tissue , supporting the mucous seal which in nature always has the tendency to contract and retreat .

[0057] The dental implant system optimi zed in a second embodiment concerns multiple implants for posterior positions with respect to the entire dental arch . I f implants inclined beyond 15 degrees are used, a standard connection pillar angled from 15 to 30 degrees in height is used . 1 or 2 mm to correct parallelism, already available on the market , and to which a customi zed temporary cap is fixed, which has a corresponding shape and externally the same as the customi zed abutment at 2-3 mm sub-gingiva and in the supragingival portion ( from 5 to 7 mm in height ) and whose internal part adapts and screws perfectly to the pillar available on the market . The multiple implant , according to one aspect of the invention, can thus use , in addition to the system already described, also a customi zed screwed abutment and a customi zed cap having the characteristics already described to correct angulations or disparallelism . The multiple implant includes a connection screw and consequently the abutment is prepared for the screw connection .

[0058] According to another embodiment , the multiple system includes a customi zed pillar angled with a dynamic curve with a maximum curvature between 15 and 22 degrees , on which the structure is positioned partly screwed and partly cemented or conometric . In immediate post-extraction implants , the cap can be used to solidi fy the implantabutment assembly with neighboring teeth, increasing its stability and therefore bone integration, giving the seal the speci fic morphology of the site and tooth considered .

[0059] According to one aspect of the invention, when the insertion axis of the screw falls vestibularly the axis can be angled, the pillar of the system is inclined at the top and internally includes , on its internal side , an angled hole with an angle between 15 and 22 degrees in which a dynamic fixing screw is housed in use . In this case , the immediate connection and customi zed pillar is also optimi zed for implants on non-regular and therefore inclined conformations .

[0060] According to an aspect of the invention, the system includes a plurality of tags , present on the surface of a coping and configured to allow scan body and scan post of the coping itsel f , i . e . detection of the impression of the coping, based on three points or tags .Alternatively, advantageously according to the invention, it is not necessary to take the impression over the head of the implant . In fact , it is suf ficient to take the shape of the abutment , read by the intra-oral scanner, and the cap is coupled onto the digital model of the abutment with a perfect fit to the base abutment , thus avoiding both scan post and scan body .

[0061] The mucosa is shaped by the cap and the provisional , and therefore the coupling with the implant is optimised . The abutment according to the invention, in its subgingival part , is made up of three areas :

[0062] - A connective attachment that remains above the bone crest that remains inviolate and undisturbed;

[0063] - A j unctional attachment that occurs on an end portion of the coping; And

[0064] - An epithelial attachment that is completed with the temporary that is inserted on the cap . The mucous seal is established at zero time and the abutment and cap help the supracrestal part to mature . The peripheral part or the visible part of the gum is completed with the temporary .

[0065] The pillars placed on the front teeth have greater aesthetic importance and for them, i f the primary integration force of the implant is less than 30 Ncm, a lineage is carried out between the cap and the neighboring teeth which, after 3 months of success ful integration, is replaced with a customi zed temporary one . coping and in harmony with the neighboring teeth, three months after the primary abutment ( implant ) .

[0066] The pillars of identical teeth placed on the right or left side of the arch are di f ferent from each other, and the system advantageously allows them to optimi ze their shape .

[0067] The Applicant has carried out experimental tests to support the ef fectiveness of the system according to the invention in terms of clot protection and implant stability . The clinical parameters determined before and after the intervention were detected using a digital impression and a sectional x-ray, taking reference points . From the veri fication of the parameters detected following the intervention and their comparison with the preintervention values , the optimi zed dental implant system has shown that the clot is protected and its di f ferentiation is promoted and, consequently, the implant is stable also reducing the time required for implantation and surgery .

[0068] Advantageously, the system according to the invention allows you to carry out , in a single moment , a single full digitally guided implant-prosthetic operation . The obj ective is therefore to aim to carry out the implant-prosthetic steps in an optimi zed way in a single solution .

[0069] The system according to the invention eliminates surgical , prosthetic and design critical issues . In fact , through the customized pillar and cap, created using speci fic digital mathematics .

[0070] Advantageously, the fact that the supra-gingival part of the abutment and its speci fic shape allows for solving prosthetic problems through the taper that the abutment itsel f presents in the 5-7 mm in height that protrudes from the gum . This taper allows for a conometric attachment between the definitive capsule and the customi zed abutment , allowing the use of cement and the risk of related peri- implantitis to be avoided or reduced to a minimum .

[0071] The pillar according to the invention is advantageous as it stabili zes , guides and protects the thickness and height of the soft tissues . The attached keratini zed tissue is a very important biological factor for the stability of the bone around the implants , it decreases the reduction in the height of the alveolar process , its adhesion to the portion of the abutment that is no longer removed decreases the influx of bacteria and plate protecting the crestal bone ( super critical area ) . The shape and conometric geometry of the abutment eliminates ( or reduces in case of cementation) the risk of peri-implantitis due to cement residues . The customi zed design of the pillar also guides , protects , performs and stabili zes the soft tissues : in the critical area TC 1 mm, in the sub critical area JE 2 mm, in the sulcular area SE 1 . 2 mm .

[0072] Furthermore , the design and morphology of the restoration are customi zed .

[0073] Advantageously, the cap and the provisional customi zed according to the invention reinforce and enhance the action of the pillar in the three aforementioned areas .

[0074] The system also advantageously allows the elimination of traditional open and non-open impressions , direct or indirect for immediate or late provisionals and to eliminate scan post and scan body .

[0075] Advantageously, the taper and height of the abutment above the gums eliminate some of the critical issues of cemented restorations . Advantageously, the height of the pillar is higher than that of the pillars currently on the market , which is limited to 3 . 5 mm and which in any case is not suf ficient for retention .

[0076] Finally, the customi zed and conometric cap is created together with the post and is inserted at the same time as the implant , this allows it to contribute to the protectionmaturation of the soft tissues which are modeled according to the design and the customi zed shape of the provisional , to avoid the execution of direct and indirect impressions during the surgical phase , of not having to wait , in the indirect modality, for the healing and maturation of the soft tissues and then shape them with provisionals that are screwed and unscrewed, which compress the tissues until the desired morphology is achieved .

[0077] Therefore , the dental implant system optimi zed according to the invention allows to optimi ze osseointegration and is dimensionally optimi zed and standardi zed .

[0078] Finally, it is clear that modi fications and variations can be made to the optimi zed dental implantology system described and illustrated here without departing from the scope of the present invention, as defined in the attached claims .
