- Abstract: This article reports a case of using immediate implant placement and immediate restoration combined with measurable implant surgical guides to restore compromised maxillary incisors caused by dental trauma. Target restoration was designed in the exoCAD software preoperatively, intraoral measurements were obtained in three directions, and the correct position of virtual implants was determined in BlueSky Plan 4. Afterward, measurable implant guides were designed and fabricated by 3D printing. Under the guidance of the measurable implant surgical guides and intraoperative measurement, the entry point was determined, the axial direction was verified when drilling to half the depth, and the 3D position was verified when drilling to total depth. Implants were inserted followed by verification once again. The temporary restoration, which was designed based on the target restoration and emergence profile of the original teeth and milled preoperatively, was connected to the implant immediately after surgery. Postoperative accuracy analysis showed that the mean linear deviations between the actual implant position and the pre-planned position were (0.57±0.17) mm at the entry point and (0.82±0.27) mm at the apex, and the mean angular deviation was (1.86±0.89) °, demonstrating that precise implant placement and immediate restoration were implemented.
