Navigated surgery with fully digital workflow
Dr. Armando Lopes
“In this clinical case, I followed a fully digital workflow during both the surgical stage (with DTX Studio™ Implant and X-Guide™) and the prosthetic stage (with DTX Studio Lab). This high-precision and straightforward approach helped me to treat my patient efficiently.”
Patient: healthy, female, 44
Clinical situation: patient missing mandibular premolar and molar teeth for several years
Surgical solution: flapless and open-flap surgery with NobelParallel™ Conical Connection NP implants, inserted using X-Guide™
Restorative solution: Multi-unit Abutment Plus and TempShell
Surgery date: October 2018
Total treatment time: same-day planning, surgery and provisionalization
Tooth positions: 35 and 37

Initial clinical situation
Radiographic and clinical images at presentation showing defects in both mandibular quadrants, where the patient has been missing premolar and molar teeth for several years.This clinical case will focus only on restoration of the narrow ridge between tooth positions 35–37, where free-hand, open flap surgery could be challenging.
The SmartFusion function in DTX Studio Implant was used to combine data from a CBCT and an intraoral scanner, to integrate both the hard and soft tissue in the planning interface. The SmartSetup function in DTX Studio Implant was then used to automatically create a virtual restoration.The 8.5 mm implant in position 37 needs placement in proximity to nerve and buccal wall. X-Guide navigated surgery helps placing the implant at high precision.

The digital treatment plan in DTX Studio Lab was used to design individualized provisional TempShell restorations, shown here on the dental scan. The files encoding the TempShell provisional restorations were exported from DTX Studio Lab for in-lab production (right).
A lightweight X-Clip is placed into the patient’s mouth and remains throughout the surgical procedure. With the X-Clip in the patient’s mouth, a further CBCT is taken in the usual way. The X-Clip is connected to a Tracker Arm to ensure proper registration between the patient, the CBCT and the surgical plan.
The X-Guide undergoes a 3-step calibration to prepare it to guide drills and position implants in real-time with dynamic 3D navigation (left).
At implant position 35, due to there being >5 mm of keratinized gingiva (buccolingually), a Tissue Punch was used to access the underlying bone (right).
The Precision Drill tip is touched against the sterile Go‑Plate, which informs the X-Guide of the exact drill length (left).

3.3 mm depth into the osteotomy preparation at implant position 35. Increasing depth is indicated by the yellow depth indicator bar on the target view and by the drill position on the cross-sectional view.
The depth indicator bar turns red when the planned implant position of 11.5 mm depth is reached. Camera views, 3D view and the implant information panel are shown in parallel.

At implant position 37, there was <5 mm of keratinized gingiva (buccolingually), so a flap was raised to access the bone and maximize soft tissue preservation (left).
The very precise X-Guide navigation allows for implant placement in proximity of buccal wall according to digital planning. NobelParallel CC NP 3.75 x 8.5 mm implant was chosen to fit the prosthetic design (right).
