Methods of designing and manufacturing customized dental prosthesis for periodontal or osseointegration and related systems

摘要

Methods of manufacturing dental prosthesis/implants each to replace a non-functional natural tooth positioned in a jawbone of a specific pre-identified patient are provided. An example method includes the steps of receiving imaging data such as x-ray image data and surface scan data of a dental anatomy and/or a physical impression of the dental anatomy of a specific preidentified patient. The steps can also include forming a three-dimensional virtual model of at least portions of a non-functional natural tooth positioned in the jawbone of the specific pre-identified patient based on the imaging and surface scan data, virtually designing a dental implant based upon the virtual model, exporting the data describing the designed dental implant to a manufacturing machine, and custom manufacturing the dental implant for the specific patient.

1. A method of manufacturing a dental implant to replace a non-functional natural tooth positioned in a jawbone of a specific pre-identified patient, the method comprising the steps of:
receiving data describing an in-vivo dental anatomy of the specific pre-identified patient associated with the non-functional natural tooth prior to removal from the jawbone of the specific pre-identified patient, the in-vivo dental anatomy to include a three-dimensional outer surface shape of at least portions of a root of the non-functional natural tooth, and a three-dimensional outer surface shape of at least portions of a crown of the non-functional natural tooth and surrounding gum tissue to define received data comprising received in-vivo imaging data; forming at least one three-dimensional virtual model of at least portions of the non-functional natural tooth positioned in the jawbone of the specific pre-identified patient responsive to at least portions of the received in-vivo imaging data, the at least one three-dimensional virtual model of the non-functional natural tooth including a modeled virtual root portion and a modeled virtual crown portion; and designing the dental implant based upon the at least one three-dimensional virtual model of at least portions of the non-functional natural tooth, the step of designing the dental implant including the steps of:
deriving a virtual occlusally-facing prosthesis interface shape from a virtual reduction of at least a substantial portion of the modeled virtual crown portion;forming a virtual dental implant body modeling a dental implant body, the virtual dental implant body including the virtual occlusually-facing prosthesis interface shape modeling a prosthesis interface of the dental implant body to receive an occlusally-facing dental prosthesis component, the virtual occlusually-facing prosthesis interface shape to include a substantially three-dimensionally contoured custom surface shape correlated to a corresponding surface shape of the modeled virtual crown portion, andforming a virtual occlusally-facing dental prosthesis component modeling an occlusally-facing dental prosthesis component, the step of forming the virtual occlusally-facing dental prosthesis component including forming a complementing virtual dental implant body-receiving surface to define a complementing virtual interface surface modeling a complementing interface surface to receive occlusally-facing portions of the dental implant body, the prosthesis interface and the complementing interface surface to create a form locking fit therebetween.
