“…In addition, Van de Wiele et al [21], in a clinical report on fully edentulous jaws, concluded that inexperience of the surgeon did not influence the accuracy when they were under the supervision by experienced surgeons. Another clinical study by Cassetta et al [22] also demonstrated the limited influence of experience on the accuracy of guided implant placement on edentulous patients.…”

Studies examining the effect of operator experience on the accuracy of static guided implant surgery have used postoperative computed tomography (CT) images to measure the error, with inconsistent results. The purpose of this study was to try to clarify this issue by using a measurement method based on the postoperative optical scan. Thirty dentists were divided into an experienced group and an inexperienced group. On a partially edentulous mandibular model in the manikin head, each dentist placed three implants via the stereolithographic (SLA) surgical guide. The implant positions were identified by a desktop scanner and compared with the planned positions using a metrology software program. No statistically significant differences were observed for any of the measured positional and angular deviations of the three implant sites between experienced and inexperienced operators (p > 0.01). All the mean values of deviations of the inexperienced group, except the depth deviation, were less than the experienced group. Implants inserted by dentists under 40 years old had significantly better accuracy than senior doctors in the global deviation at implant apex (p = 0.006). Within the limits of this study, we concluded that operator experience is not a critical factor in achieving the accuracy of guided implant surgery via the tooth-supported SLA surgical guide. Large deviations could occur even with the aid of the SLA surgical guide, and care must be taken to avoid errors for both experienced and inexperienced operators.

“…Implant positioning in relation to planned definitive prostheses can be enhanced using computer-guided static or dynamic systems. [1][2][3][4][5] Static guided implant placement surgery involves the use of a cone beam computed tomography (CBCT) generated surgical guide with metal surgical tubes. These static guides can either be supported by adjacent natural teeth, mucosa or alveolar bone.…”

“…[1][2][3][4][5] Static guided surgery has been shown to be more accurate than free hand implant placement. [1][2][3][4][5] Recent development of inexpensive three-dimensional (3D) printers allows cost-effective static guide fabrication and therefore have popularised the method. 4 Implant positioning is predetermined in a static guide; however, the static guide does not allow for real-time adjustments when needed or visualisation of the osteotomy.…”

“…While tooth-supported or mucosal-supported static guided surgery is indicated with flapless surgery when bone grafting or osseous modification is not needed, static guided surgery can be difficult in patients with limited mouth opening, implant sites with difficult access or direct visualisation, as well as implant placement in limited horizontal spaces between adjacent teeth. 5 Dynamic navigation surgery allows the operator to fully visualise the osteotomy and implant site on the computer screen while preparing the osteotomy site and placing an implant fixture. The accuracy of dynamic navigation has been observed to be comparable to that of static guided placement.…”

Introduction:Recent computer-guided dynamic navigation systems promise a novel training approach for implant surgery. This study aimed to examine learning progress in placement of dental implants among dental students using dynamic navigation on a simulation model. Materials and Methods:Senior students with no implant placement experience were randomly assigned five implant placement attempts involving either three maxillary or four mandibular implants distributed in the anterior/posterior, and left/right segments. Implant placement was planned using a Navident Dynamic Guidance system. Surgical time was recorded. Horizontal, vertical and angulation discrepancies between the planned and placed implant positions were measured using superimposed CBCT scans. Data were analysed with repeated measures regression with Tukey's adjusted pairwise comparisons (α = 0.05).Results: Fourteen students participated, with a mean age of 26.1 years and equal males and females. Mean time for implant placement was associated with attempt number (P < 0.001), implant site (P = 0.010) and marginally related to gender (P = 0.061). Students had a significant reduction in time from their first attempt to their second (10.6 vs 7.6 minutes; adjusted P < 0.001) then plateaued. Overall 3D angulation (P < 0.001) and 2D vertical apex deviation (P = 0.014) improved with each attempt, but changes in lateral 2D (P = 0.513) and overall 3D apex deviations (P = 0.784)were not statistically significant. Implant sites were associated with lateral 2D, 2D vertical and overall 3D apex deviation (P < 0.001).Discussion: Males were marginally faster than females, had slightly lower overall 3D angulation, and reported higher proficiency with video games. Novice operators improved significantly in speed and angulation deviation within the first three attempts of placing implants using dynamic navigation. Conclusion:Computer-aided dynamic implant navigation systems can improve implant surgical training in novice population. K E Y W O R D Sdental implants,

“…the clinician's experience influence in the final result is controversial. Some studies conclusions (28) show that the experience in conventional implant placement is an essential condition for the guided surgery good prognostic, but the results of the experienced surgeons were quantified in studies in the dynamically guided surgery (28), especially in terms of implant depth accuracy (29). guided surgery has a positive correlation with reduced surgical complications (30).…”
