A dental drill-guide 24 for guiding the drilling of dental-implant cavities in an edentulous maxillary or mandibular arch 10, 12 has a plurality of orthodontic screw-seats 26 which are engagable with a plurality of orthodontic screws 14 inserted into the osseous tissue and which extend through the gingival mucosa. Three dimensional oral information data from mucosal impression data of an edentulous maxillary or mandibular arch 10, 12 having a plurality of orthodontic screws 14, along with image data of the edentulous maxillary or mandibular arch 10, 12 is used to determine dental implant position data for the insertion of one or more dental implants 16 into the edentulous maxillary or mandibular arch 10, 12 relative to the positions of the orthodontic screws 14. Using the dental implant position data, it is possible to form dental implant drill-guide parameter data for the creation of a dental implant drill-guide 24. A dental implant drill-guide system 50 having two-part orthodontic screws is also disclosed. |
