“…In our setting, this friction was reduced to a minimum by the drills being positioned in the center of each handle. Under clinical conditions, generally speaking a loose fit between drill and sleeve potentially causes eccentric forces, which lead to more friction and greater heat development (Laederach, Mukaddam, Payer, Filippi, & Kühl, ). A greater temperature difference between guided and conventional drilling procedures was observed in the current study for large diameter drills and larger drill flutes because of the influence of water irrigation.…”

Objectives The aim of this in vitro study was to compare the heat generation during guided osteotomy preparation (GOP) with that of a conventional approach (CA) for a single and sequential drilling protocol. Methods Temperature measurements were performed during standardized osteotomy preparations in polyurethane foam blocks with an infrared camera. The four groups included single and sequential drilling with and without the use of a surgical guide. In the first group (single CA) and the second group (single GOP), only the final drills diameters were applied once. In the third group (sequential CA) and the fourth group (sequential GOP), two to four drills with increasing diameters were applied. Guided and conventional as well as single and sequential drilling were compared using a one‐way ANOVA with Tukey post hoc test. The level of statistical significance was set at α = 0.05. Results Guided osteotomy preparation showed statistically significant higher temperatures than CA for the 2.2 mm, the 3.5 mm, and the 4.2 mm drill (p = 0.032, p = 0.005 and p < 0.001, respectively). Sequential drilling led to higher heat generation and longer duration of latent heat than single drilling. For all drilling procedures, the duration of heat exposure over critical temperature was less than 1 min, except for the sequential GOP drilling protocol with the 4.2 mm drill (76 s). Conclusions Guided drilling requires specific attention to heat development. When guided implant surgery is performed, a single drilling procedure could alleviate heat production compared to a sequential procedure.

“…The anatomic radiographic fidelity of bone structures and accuracy of linear measurements are crucial for basic preoperative implant planning, and even more so when applied in image‐guided implant surgery (Nickenig & Eitner, ; Schneider, Marquardt, Zwahlen & Jung, ; Vieira, Sotto‐Maior, Barros, Reis & Francischone, ). All guided surgery systems incorporate some degree of imprecision resulting in horizontal and particularly vertical deviations of the actual position of the implant compared to the presurgical virtual position (Laederach, Mukaddam, Payer, Filippi & Kuhl, ; Schneider et al., ; Vercruyssen et al., , , ).…”

Objective: The aim of this systematic review was to identify, review, analyze, and summarize available evidence on the accuracy of linear measurements when using maxillofacial cone beam computed tomography (CBCT) specifically in the field of implant dentistry. Material and methods:The search was undertaken in April 2017 in the National Library of Medicine database (Medline) through its online site (PubMed), followed by searches in the Cochrane, EMBASE, ScienceDirect, and ProQuest Dissertation and Thesis databases. The main inclusion criterion for studies was that linear CBCT measurements were performed for quantitative assessment (e.g., height, width) of the alveolar bone at edentulous sites or measuring distances from anatomical structures related to implant dentistry. The studies should compare these values to clinical data (humans) or ex vivo and/or experimental (animal) findings from a "gold standard." Results:The initial search yielded 2,516 titles. In total, 22 studies were included in the final analysis. Of those, two were clinical and 20 ex vivo investigations. The major findings of the review indicate that CBCT provides cross-sectional images that demonstrate high accuracy and reliability for bony linear measurements on crosssectional images related to implant treatment. A wide range of error has been reported when performing linear measurements on CBCT images, with both overand underestimation of dimensions in comparison with a gold standard. A voxel size of 0.3 to 0.4 mm is adequate to provide CBCT images of acceptable diagnostic quality for implant treatment planning.Conclusions: CBCT can be considered as an appropriate diagnostic tool for 3D preoperative planning. Nevertheless, a 2 mm safety margin to adjacent anatomic structures should be considered when using CBCT. In clinical practice, the measurement accuracy and reliability of linear measurements on CBCT images are most likely reduced through factors such as patient motion, metallic artefacts, device-specific exposure parameters, the software used, and manual vs. automated procedures.

“…Another possible explanation for the few large deviations is the technical skills of the surgeon. In an in vitro study, Laederach et al [27] concluded that the clinician might have considerable influence on the accuracy of sGIS when applying eccentric forces. Considering the simulation was executed in a well-controlled environment, the few large deviations could be attributed to the personal technical skills of individual surgeon.…”

A distal free-end situation could result in insufficient stability of the surgical guide, and could reduce accuracy of the static guided implant surgery (sGIS). The purpose of this study was to investigate the accuracy of sGIS using a combination tooth-and-bone supported stereolithographic (SLA) surgical guide in distal extension situation. Thirty dentists, each placed three implants at the Federal Dentaire Internationale (FDI) teeth positions #46, #47 (a distal extension situation), and #36 (a single tooth gap) via the surgical guide on a model fixed to a manikin. Pre- and post-operative computed tomography (CT) images of the models were superimposed, and the positional and angular deviations of the implants were measured with metrology software. An analysis of variance (ANOVA) test was performed to evaluate the intergroup differences. No significant differences were found for all the positional and angular deviations among the three implant sites, except the bucco-lingual deviation at the implant platform in the #47 position (0.43 ± 0.19 mm) that was significantly larger than the #46 (0.21 ± 0.14 mm) and #36 (0.24 ± 0.25 mm) positions (p < 0.0001). Within the limits of this study, we conclude that, in distal extension situation of missing mandibular molars, adding a bone-supported strut in the distal part of the surgical guide can be beneficial to the accuracy of the sGIS.
