Abstract

A custom dental implant and a method and system for making the custom dental implant having one or more energy storing devices that deflect during installation and expand to provide stability after insertion in a natural dental socket of a patient.

Claims (19)

1. A method of comprising the steps of;

assessing an implant site of a patient to determine an initial stability required, for a custom spring-loaded dental implant, based on at least a quality and quantity of alveolar bone of the patient;

computing, responsive to said assessing, an amount of flexibility required for at least one flexible energy storing device of the custom spring-loaded dental implant;

receiving three-dimensional data representing a shape of a natural extraction socket of a tooth of the patient;

analyzing the three-dimensional data to obtain information about characteristics of the natural extraction socket;

designing a three-dimensional image of the custom spring-loaded dental implant based on the characteristics of the natural extraction socket, the designing step including designing the three-dimensional image of the custom spring-loaded dental implant to have (i) an occlusal facing portion for receiving a restoration or forming an integral part of the restoration, (ii) a mid-portion configured to have a desired emergence profile, (iii) an apical portion including one or more prongs and (iv) the at least one flexible energy storing device,

designing the at least one flexible energy storing device to be along or integrated into the custom spring-loaded dental implant and having the computed flexibility,

wherein said designing step of the at least one flexible energy storing device is based on information selected from the group consisting of (i) location of the tooth replacement, (ii) geometry of the alveolar bone, (iii) amount of periodontal ligament fibers present, (iv)initial stability required after implant placement, (v) location of neighboring nerves and (vi) quality or quantity of bone required for support of the custom spring-loaded dental implant

wherein the method further comprises:

fabricating the custom spring-loaded dental implant based on said designing step: and

inserting, responsive to the fabricating, the fabricated custom spring-loaded dental implant into said natural extraction socket, without said inserting altering the shape of the natural extraction socket, by the at least one flexible energy storing device substantially deflecting in a spring-like manner during insertion and therefore allowing for less overall force to install the custom spring-loaded dental implant than the force used to install conventional implants, and subsequently expanding to provide external pressure to stabilize the custom dental implant in the natural extraction socket during osseointegration.

2. The method according to claim 1 , further comprising scanning the tooth to obtain said shape of the natural extraction socket prior to receiving the three-dimensional data.

3. The method according to claim 2 , further comprising scanning the tooth before extracting said tooth.

4. The method according to claim 2 , further comprising scanning the too after extracting said tooth.

5. The method according to claim 2 , further comprising performing the scanning step with a Computer Tomography (CT) machine, Cone Beam Computed Tomography (CBCT) machine, intraoral digital scanner and/or Magnetic Resonance Imaging (MRI) machine.

6. The method according to claim 1 , further comprising designing the at least one flexible energy storing device to fully or partially surround the mid-section and or prongs of the custom dental implant.

7. The method according to claim 1 , further comprising designing an internal portion of the custom dental implant to mimic anti-rotation features, threads and/or connection geometries of screw form dental implants to support a restoration.

8. The method of claim 1 , wherein the computing is carried out using a finite element analysis.

9. The method of claim 1 , further comprising fabricating the at least one flexible energy storing device with a material that withstands plastic failure.
