ONE PIECE CUSTOM MADE DENTAL DEVICE FOR HOLDING MULTIPLE TEETH

Abstract

A one piece custom made dental device for holding multiple teeth comprises a mono block of dental implants (4), abutments (1), supracrestally or supragingivally connecting bars (2) and pontics (3). Implant (4) is made up of flat and broad base (4.1) and implant body portion (4.4) having vertical threads (4.3), inverted thread (4.2), crestal supporting thread (4.5). Implant (4), abutments (1) and pontics (2) are fabricated according to an individual's bone and gum data to form mono block structure without any screw and joints in such a manner as to distribute stress and strain on integrated dental implants. Multiple implants are integrated through supracrystally or supragingivally connecting bars (2). The dental device of the present invention is designed to achieve faster placement and implantation process with minimal bone loss and minimal micro movements. The present device reduces time required for healing and cost of whole implantation and prosthesis process drastically.

4. A one piece custom made dental device for replacing multiple teeth as claimed in claim 2, wherein the mono block is manufactured from zirconia and/or titanium.

Description

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS

[0038] The features of the invention, and its technical advantages, can be seen from the following description of preferred embodiments together with the claims and the accompanying schematic drawings, in which:

[0039] FIG. 1 is a perspective view of present invention to replace 4 teeth with 3 dental implants

[0040] FIGS. 2A and 2B are perspective views of the present invention placed within jaw bone with multiple implants and pontics.

[0041] FIGS. 3A and 3B are perspective views of the dental implant.

[0042] A one piece custom made dental device as illustrated in FIG. 1 of the drawings, comprises an abutment (1), supracrestal or supragingival connecting bar (2), pontics (3) and a dental implant (4). An abutment (1) or pontics (3) superstructure is to receive a final prosthesis. The abutment (1) or pontic (3) is tapered towards the occlusal surface with or without internal thread and with or without external groove. Each implant has a supracrestal connecting bar (2) to integrate with the next implant with abutments made receivable for prosthesis according to bone data. Abutments can also be made detachable. The shape and size of the abutment is variable according to the receivers' requirement and bone data.

[0043] The supracrestal or supragingival connecting bar (2) are without any screw or joint and are used to integrate the two or more dental implants (4) as a one piece structure.

[0044] A dental implant (4) portion of the framework forms root for the teeth. It is custom made and manufactured in various sizes and shapes according to the receiver's bone data. The dental implant of titanium and zirconia material is preferred in dental device according to present invention. Also the complete mono block can be manufactured in zirconia in addition to titanium.

[0045] The one piece framework reduces to a greater extent the micro movements and other forces acting on the framework during function by distribution of forces and makes it much greater load bearing capacity.

[0046] FIG. 2A illustrates another form of the invention wherein a one piece custom made dental device is placed within the jaw bone with multiple implants and pontics. It shows entire one piece frameworks used in case of full jaw restoration for fixed prosthesis.

[0047] FIG. 2B shows an entire one piece framework used in case of full jaw restoration for screw retained prosthesis.

[0048] As shown in the FIGS. 2A and 2B the dental implants (4) are integrated in one piece supracrestally i.e. above the bone (5) and thus minimize the bone loss.

[0049] FIG. 3A is perspective view of the dental implant with fixed prosthesis used in the dental device.

[0050] FIG. 3B is perspective view of the dental implant with screw retained prosthesis used in the dental device.

[0051] The dental implant (4) portion of mono block comprises wide base (4.1), inverted thread (4.2), vertical thread (4.3), implant body portion (4.4), and crestal supporting thread (4.5).

[0052] Dental implant (4) is custom made and manufactured in various sizes and shapes according to the patient's (receiver's) bone data. The bone data is used to determine the length and diameter of the implant body portion (4.4). The implant body portion (4.4) may be made as long and wide as required so as increase the primary stability significantly. The surface area of the implant body portion (4.4) can also be increased greatly for greater bone implant contact providing higher primary and secondary stability. The surface area of the implant body portion (4.4) is textured through available process like HA MTX, SLA, nanotechnology, etc. to accelerate osseointegration process.

[0053] Abutment (1) includes an abutment portion, optional thread, and groove. Abutment portions are made according to the receiver's requirements either for 2 or more or for all teeth. The abutment portion may be a screw retained prosthesis abutment portion (1B) or fixed prosthesis abutment portion (1A) as illustrated in FIG. 3B and FIG. 3A respectively. The optional thread into the abutment or into the base of the crestal side is for a screw retained prosthesis (1B). There is a groove on the body of the abutment to add a silicone ring or other metal rings for cushioning effect of the prosthesis.

[0054] The wide base (4.1) of all implants portions are flat and broader than the implant body portion (4.4) at the lower one third. The broader and flat base reduces the shear forces of occlusion to greater extent than conventional implants without the base. The base (4.1) may be rectangular or circular in shape.

[0055] The inverted threads (4.2) are used to divert the forces laterally thereby reducing the forces apically. The vertical threads (4.3) are used to tap the implant at required place in the bone with ease. The Crestal supporting thread (4.5) is used for firm contact with crestal bone.

[0056] The dental implants' (4) supracrestal area either subgingivally, supragingavally or at gingival level includes a flare with a shoulder or chamfer. The shoulder and chamfer is to give finishing margins for the prosthesis as determined by the professional.
