APPARATUS AND METHOD FOR REHABILITATION OF GUM ARCHITECTURE

Abstract

The invention relates to dental field, more specifically in the field of periodontics, and describes the construction and working of a modular gum architecture device made of inert, biocompatible, bone-integrable and/or absorbable material to replace in part or totally the lost alveolar bone and restore the anatomy of the gum around the tooth or implant. The device may recreate the region of the interdental papilla or may fill in empty spaces caused by protocol-type prostheses (fixed dentures). It can also serve as support for teeth already softened or softening, for implants already installed or even for implants to be installed.

DETAILED DESCRIPTION OF THE INVENTION

[0035] The device may have different formats that will depend on the need for the surgical procedure and the patient's situation. It can be: [0036] A single piece for total edentulous (110); [0037] A single piece with two or more holes for teeth/implants; [0038] A single piece for only one tooth/implant (210); [0039] The configuration (210) divided in half in a mesio-distal direction (310); [0040] The configuration (310) be subdivided into small modules of buccal-lingual sense (410 to 450 and 410 to 450); [0041] Or any combination of the items mentioned above. [0042] From inert solid material, biocompatible, bone-integrable and in some cases resorbable.

[0043] The device can be installed in a single or combined way (FIGS. 5 and 6 exemplifies a type of case), and each part/module may vary in size and volume to solve cases of uneven generation.

[0044] It must have a hole (120) for whole pieces or a curvature (120) resulting from the cutting of the modules to fit the natural tooth and/or implant, which may contain threads to assist in fixing implants (810). Although represented only in FIGS. 17 and 18, the device must have holes in all its configurations and accessories 1710 for irrigation, tissue fixation and/or for fixing the device to the bone through pins as well as serving as a storage compartment (frame) of biomaterial, allowing to protect it, resulting in an acceleration of nutrition, vascularization and innervation, consequently an acceleration of bone regeneration.

[0045] The device may have a lateral flap (130) in the interproximal region (between spaces of teeth and/or implants) that will serve as support for the connective tissue featuring in an interdental papilla structure. It may have a lower flap in the occlusal-cervical direction (710) to supply cases of bone lack in this direction.

[0046] It also has joints for better adaptation to the recipient bone bed, and these joints can be in the interdental (1010) and/or in the cervical (1110) and/or vestibular (1210) regions, combining with the occlusal-cervical flap (710).

[0047] There may also be a superstructure (1310) in the device to increase volume and height capable of supplying cases of loss of extreme bone. They provide modules (1510 to 1550 and 1510 to 1550) to fit with the device's modules (410 to 450 and 410 to 450). The superstructure (1310) can be combined, as shown in FIG. 16, to achieve greater height and volume.

[0048] The device can be contained in a biomaterial or material block that presents good biocompatibility and integrability, in a stratified way, to present better volume, compatibility and integrability characteristic. This combination of block and device will allow the professional to machine the block in order to solve the case.

[0049] The device must be installed below the gum and, according to each case, it can be attached to the bone or glued by pins in a juxtaposed, overlapping, semi-intraosseous or stratified way (recipient bone, particulate bone device or even between bone blocks).

[0050] In addition to the device, it is possible to rehabilitate the hard (bone) and soft (gum) tissues by a method of detaching the gum, similar to a bariatric surgery, and injecting biocompatible, bone integrable, inert, polymerizable, catalytic and catalytic and passable biomaterial modeling of the lost gum architecture, as well as having a rubber or silicone structure. Another method is to introduce a bladder-like structure in the form of a papilla below the gum where the tunnel detachment was made in the region surrounding the tooth or implants and the papilla. After the insertion of the bladder, it is filled with silicone or biomaterial capable of catalysis in order to take the shape of the necessary or desirable gum architecture.

[0051] Rehabilitation also occurs in case of more severe bone loss, including in the region of the basal bone (jaw and mandible) and in the region of the alveolar bone (bone below the alveolar bone that circulates natural teeth or implants).

[0052] The features of the device and method solve the problems of lack of alveolar bone as well as rehabilitate the gum architecture, giving a natural and pleasant aesthetic appearance to the user.
