3D printed bone supported maxillary sinus surgical guide and method of use
An accurate and precise surgical guide for dental procedures, especially a procedure involving a subject with few or no teeth as well as methods for making and use of such guides.
1 . A dental implantation method for a patient missing one or more teeth, comprising:
fitting or installing a 3D printed bone supported maxillary sinus surgical guide adjacent to a maxilla in the mouth of the patient thereby marking access to the sinus, then
installing a tooth implant in the maxilla of the patient, wherein during the installing one or more surgical instrument is viewed and positioned with the 3D printed bone supported sinus surgical guide;
wherein prior to the placement of the 3D printed bone supported sinus surgical guide in the mouth of the patient, the method further comprises:
making the 3D printed bone supported maxillary sinus surgical guide by:
obtaining an STL file describing a maxillary bone structure of the patient as imaged by cone beam computerized tomography (“CBCT”);
producing an STL file describing the 3D printed bone-supported maxillary sinus surgical guide using implant planning software and the STL file describing the maxillary bone structure of the patient;
3D printing the 3D printed bone-supported maxillary sinus surgical guide from a UV curable resin using the STL file describing the 3D printed bone-supported maxillary sinus surgical guide, and curing the UV curable resin with light;
3D printing a scale model that comprises maxillary surfaces in contact with the 3D printed bone-supported maxillary sinus surgical guide from a UV curable resin using the STL file describing the maxillary bone structure of the patient, and curing the UV curable resin with light; and
test fitting the 3D printed bone-supported maxillary sinus surgical guide to the scale model.
2 . The method of claim 1 , wherein the UV curable resin is cured without heat curing.
3 . The method of claim 1 , wherein obtaining the STL file describing the maxillary bone structure of the patient comprises transforming data in a digital imaging and communications in medicine (DICOM) file into an STL file using DICOM reconstruction software.
4 . The method of claim 1 , further comprising performing a CBCT scan of the maxillary bone structure of the patient.
5 . The method of claim 1 , wherein producing the STL file describing the bone-supported maxillary sinus surgical guide comprises determining a position of a window that covers a lateral wall of the sinus and zygomatic process of the maxilla.
6 . The method of claim 1 , wherein producing the STL file describing the bone-supported maxillary sinus surgical guide comprises determining a tooth implant position.
7 . The method of claim 1 , wherein producing the STL file describing the bone-supported maxillary sinus surgical guide comprises contouring and/or smoothing the design of the bone-supported maxillary sinus surgical guide.
8 . The method of claim 1 , further comprising surgically forming a lateral sinus window using the 3D printed bone-supported maxillary sinus surgical guide.
9 . The method of claim 1 , further comprising performing a sinus lift or sinus augmentation using the 3D printed bone-supported maxillary sinus surgical guide.
