Accuracy of a real‐time surgical navigation system for the placement of quad zygomatic implants in the severe atrophic maxilla: A pilot clinical study

Abstract

A real-time surgical navigation system used for the placement of quad zygomatic implants demonstrated a high level of accuracy with only minimal planned-placed deviations, irrespective of the lengths or locations of the implants.

Computer-Aided Rehabilitation Supported by Zygomatic Implants: A Cohort Study Comparing Atrophic with Oncologic Patients after Five Years of Follow-Up

“…Thus, the need for a stereolithographic model to simulate the surgery beforehand can be avoided [ 29 ]. Real-time surgical navigation can aid the surgeon in reproducing the planned implant trajectories [ 30 ]. Several clinical trials have reported satisfactory accuracy of dynamic navigation in standard implant placement [ 31 , 32 , 33 ].…”

“…Several clinical trials have reported satisfactory accuracy of dynamic navigation in standard implant placement [ 31 , 32 , 33 ]. Only a few studies [ 30 , 34 ] have reported on the dynamic navigation concept for zygomatic implant placement, but with very encouraging results including a deviation of 1.35 mm at the entry point and a deviation of 2.15 mm at the apex [ 34 ]. Zygomatic implant site preparation is a demanding technique due to the need of a very long drill.…”

Long‐term Schneiderian membrane thickness changes following zygomatic implant placement: A retrospective radiographic analysis using cone beam computed tomography

“…Zygomatic implants have been proved effective in the management of extremely atrophic edentulous maxillae, with high implant survival rates reported in some clinical studies (Aparicio, Manresa, Francisco, Aparicio, et al, ; Aparicio, Manresa, Francisco, Ouazzani, et al, ; Balshi, Wolfinger, & Balshi, ; Davó, Malevez, & Rojas, ; Duarte, Filho, Francischone, Peredo, & Branemark, ). Compared with traditional bone graft techniques, the benefits of zygomatic implantation include the lack of a need for bone grafting, a shorter treatment period, and the possibility for immediate loading, as well as other factors (Aparicio, Manresa, Francisco, Claros, et al, ; Hung et al, ; Wang et al, ).…”

Three-Dimensional Radiographic Evaluation of the Malar Bone Engagement Available for Ideal Zygomatic Implant Placement

“…Various implant trajectories can be chosen depending on the surgeon's preference for an intra-or extra-sinus approach. Differences in zygoma implant intra-malar length by sector were reported by Bertos Quilez et al [26] and Hung et al [20]. Rossi et al [23] also found a statistically significant difference between the mean length from the crestal point to the orbital socket in both the canine (53.42 ± 4.08 mm) and premolar (42.47 ± 3.20 mm) regions.…”

“…Some authors [ 20 , 21 , 22 ] have performed extensive research regarding the extent of zygomatic bone in which implants can be inserted. However, the data are insufficient to evaluate the most adequate implant position and trajectory in order to engage the greatest amounts of malar bone.…”
