Method for manufacturing dental implant components
View Patent ↗A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. The method takes an impression of a mouth including a first installation site having a dental implant installed in the first installation site and a gingival healing abutment having at least one informational marker attached to the dental implant. A stone model is prepared based on the impression, including teeth models and model markers indicative of the at least one informational marker. The model is scanned. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker is determined to gather information for manufacturing the rapid prototype. Rapid prototype dimensional information is developed. The rapid prototype dimensional information is transferred to a rapid prototyping machine which fabricate a rapid prototype of the patient's dentition as well as a dental implant analog position.
1. A method of making a physical model of at least a portion of a patient's mouth having a dental implant installed therein, the physical model to be used in developing a prosthetic tooth to be coupled to the dental implant, comprising:
receiving scan data including information about a location of the dental implant installed in the patient's mouth;
developing a virtual three-dimensional model of at least a portion of the patient's mouth from the scan data;
developing a first data set to be used in fabricating the physical model of at least the portion of the patient's mouth;
developing a second data set to be used in developing a custom dental abutment; and
fabricating, by use of the first data set and the second data set, the physical model of at least the portion of the patient's mouth and the custom dental abutment positioned at a location in the physical model that corresponds to the location of the dental implant installed in the patient's mouth, the custom dental abutment integral with the physical model.
2. The method of claim 1 , wherein the fabricating the physical model and the custom dental abutment include manufacturing the physical model and the custom dental abutment via rapid prototyping.
3. The method of claim 1 , wherein the custom dental abutment is integral with the physical model such that no assembly between the custom dental abutment and the physical model is required.
4. The method of claim 1 , further including:
prior to the receiving scan data, scanning at least the portion of the patient's mouth having the dental implant installed therein.
5. The method of claim 4 , further including:
prior to the scanning the at least the portion of the patient's mouth, installing the dental implant in the mouth of the patient.
6. The method of claim 5 , further including:
prior to the scanning the at least the portion of the patient's mouth, attaching an attachment member to the installed dental implant, the attachment member including features for identifying the location of the installed dental implant during the scanning.
7. The method of claim 1 , wherein the fabricating the physical model includes adding a soft tissue element surrounding the custom dental abutment.
8. A method of making a physical model of at least a portion of a patient's mouth having a dental implant installed therein, the physical model to be used in developing a prosthetic tooth to be coupled to the dental implant, comprising:
receiving scan data including information about a location of the dental implant installed in the patient's mouth;
developing a virtual three-dimensional model of at least a portion of the patient's mouth from the scan data;
developing a first data set to be used in fabricating the physical model of at least the portion of the patient's mouth;
developing a second data set to be used in developing a custom dental abutment; and
fabricating, by use of the first data set, the physical model of at least the portion of the patient's mouth, the physical model having a blind hole that is positioned at a location in the physical model that corresponds to the location of the dental implant installed in the patient's mouth.
9. The method of claim 8 , further including:
by use of the second data set, manufacturing the custom dental abutment, the custom dental abutment to be attached to the blind hole in the physical model so as to allow the fabrication of a tooth-like restoration on the custom dental abutment, the prosthetic tooth comprising the tooth-like restoration and the custom dental abutment.
10. The method of claim 9 , wherein the custom dental abutment is configured to be attached to the blind hole via a screw.
11. The method of claim 8 , wherein the fabricating the physical model includes adding a soft tissue element surrounding the blind bore.
12. A method of making a physical model of at least a portion of a patient's mouth having a dental implant installed therein, the physical model to be used in developing a prosthetic tooth to be coupled to the dental implant, comprising:
receiving scan data including information about a location of the dental implant installed in the patient's mouth;
developing a virtual three-dimensional model of at least a portion of the patient's mouth from the scan data, the virtual three-dimensional model for creating a first data set to be used in fabricating the physical model of the at least a portion of the patient's mouth;
fabricating, by use of the first data set, the physical model, the physical model having an implant analog structure that is positioned at a location in the physical model that corresponds to the location of the dental implant installed in the patient's mouth, the implant analog structure having features corresponding to the installed dental implant.
13. The method of claim 12 , wherein the scan data is derived from a scan of at least the portion of the patient's mouth.
14. The method of claim 12 , wherein the implant analog structure is an implant analog attached to the physical model.
15. The method of claim 12 , wherein the implant analog structure is made of a same material as the physical model.
16. The method of claim 12 , wherein the physical model includes a receptacle leading to the implant analog structure.
17. The method of claim 16 , wherein the receptacle is partially defined by a compliant soft tissue element.
18. The method of claim 12 , wherein the implant analog structure is an implant analog receptacle that corresponds to an external geometry of the dental implant installed in the patient's mouth.
