“…This may be related to the difficulty in keeping sight of the display during the surgical procedure (in the sense of being counter-intuitive for the surgeon as noted in the present case reports), a situation clearly related to the requirement of a learning curve. This finding was previously reported in a study aiming to compare the accuracies between the navigated system, the laboratory guide, and freehand drilling in cast models: The authors registered a higher accuracy in total errors at the entry and apex, lateral error and apex, and angular error for the navigated system and laboratory guide compared with freehand drilling [14]. Additionally, despite the greater attention needed to operate, the navigation system demonstrated higher accuracy in angular error compared to the laboratory guide, a situation that may be related with the necessary sleeve tolerance in the laboratory guide (the space between the metal ring and the sleeve and between the sleeve and the drill to allow cooling water circulation and drill rotation) [14].…”

“…All these factors may pose contraindications for implant placement using static guidance, challenges that in a large proportion can be potentially overcome by the dynamic navigation system. There are several advantages related to the use of dynamic navigation-assisted surgery: first, its accuracy is accomplished independently of CAD-CAM stents that, when fabricated with any inaccuracy, can introduce significant perioperative complications [12]; second, the dynamic navigation system provides time-and cost-effective surgery by enabling the patients to be scanned and surgery planned on the same day as surgery [5,7] to perform immediate function and to manufacture the implant-supported fixed prosthesis in reduced time; third, the possibility of performing treatment independently of the patients' limited mouth opening capability [13]; and fourth, the freedom to change the implant size, system, and location during the surgical procedure, given the possibility of a direct view of the surgical field [14,15].…”

Background: This case series describes the surgical workflow during maxillary full-arch rehabilitations in two patients through the All-on-4 concept (standard and hybrid) assisted by DTX Studio Implant Software planning and X-Guide Navigation. Results: The X-Guide Navigation enabled the drills and implants to be positioned and oriented precisely, allowing the implants to be positioned favorably under the surgical and prosthetic points of view through the avoidance of damage to the maxillary sinus and nasal cavity. Dynamic navigation-assisted surgery provided advantages, including the possibility to modify the implants’ system, length, or location perioperatively. However, it must be underlined that to achieve proficiency with this technology it is necessary to consider a necessary learning curve. Conclusion: The insertion of dental implants assisted by dynamic navigation for maxillary full-arch rehabilitations was considered a safe and predictable procedure. Nevertheless, it can be improved (such as with a simpler fiducial markers protocol), aiming to simplify the procedure.

“…First, the inability to accurately and reliably transfer the exact CBCT planned implant position to the clinical scenario. Nevertheless, computer guided implant planning has been shown to improve the predictability and accuracy of implant placement . Also, the results of this investigation are only applicable to the utilization of a specific size of implants.…”

Background The nasopalatine canal (NPC) is of special importance when considering implant therapy in the maxillary central incisors' region. Purpose To investigate the incidence of NPC perforation in relation to virtual immediate implant placement. Materials and Methods A search through the cone beam computed tomography (CBCT) database of The University of Oklahoma—College of Dentistry was conducted. First, canal related measurements were conducted. Second, digital prosthetic planning was performed. Then, immediate implants were virtually placed and additional measurements were performed. Perforation rate was assessed. Last, data obtained was statistically analyzed. Results A total of 217 scans fulfilled the inclusion criteria. Only 8% of cases showed NPC perforation. The perforation occurred at mid‐third of the implant or at the mid and apical third in 33% and 22% of the cases, respectively. A statistically significant association was found between perforation of NPC and bone width palatal to the root of the central incisor (P < .0001) as well as canal angulation (P = .0196). NPC angulation (°) and palatal bone width (mm) predisposed to a higher risk of perforation. Only 27.78% of the perforations could be overcome by the installation of shorter implants. Conclusions Low incidence of NPC perforation could be expected when immediately placing implants in the maxillary incisor region.

“…Pernar et al [15] also reported that the presence of bone spine causes drills to move up and down unsteadily when using dental implant navigation systems alone and thus results in errors. However, Chen et al [20] showed that the dental implant navigation system enables dentists to identify insertion depths and the location of the guide stents with sleeves, reducing the incidence of dental implant devices moving up and down.…”

The aim of this study was to compare the accuracy of implant placement by using the conventional freehand method, the surgical guide alone, the dental navigation system alone, and the dental navigation system with a surgical guide. The participants were aged 20 years or older and were requiring dental implant surgery according to an assessment made by a dentist between July 2014 and December 2017. A total of 128 dental implants were inserted, 32 dental implants in each group, and participants with similar or identical age (i.e., 20–50 years or 50 years or above) and missing tooth locations were paired for comparison. Accuracy was measured by overlaying the real position in the postoperative Cone Beam Computerized Tomography (CBCT) on the virtual presurgical placement of the implant in a CBCT image. Using the dental navigation system with a surgical guide could help dentists to position implants more accurately. Total, longitudinal, and angular error deviation were significantly different (p < 0.0001). The same level of accuracy could be obtained for the different jaws and tooth positions. The one-way analysis of variance (ANOVA) showed that the total, longitudinal, and angular errors differed significantly (p < 0.0001). A comparison of the four dental implant surgical methods indicated that the combination of a dental implant navigation system and a surgical guide kit achieved the highest accuracy in terms of the different tooth positions and jaws.
