“…First of all, the impressions must be taken with extreme precision trying to go as far as the reading of the fornix in order to then obtain adequate templates for the length of the corticotomy lines. The presence of orthodontic brackets during the impression could create inaccuracies for the subsequent construction of the template, but today this problem is solved by the intraoral scanner and the development of a digital model ( 5 ). During the impression phase, attention must be paid to the relief of the frenulum which could then complicate the correct insertion of the surgical guide ( 7 ).…”

“…The successive advent of intraoral scanners introduced a three-dimensional (3-D) vision of the dental arches in STL format (an acronym for “ Standard Triangulation Language ”); these data in STL format can be matched or overlapped with the three-dimensional information of the CBCT using dedicated software ( 4 , 5 ). The integration of all these digital information results in a digital workflow that permits more details and accuracy of surgical and orthodontic setups.…”

Orthodontics has considerably increased the use of technology combined with surgery as a tool to improve dental movements in terms of predictability, acceleration of movement, and fewer side effects. To achieve these goals miniscrews and corticotomy were introduced. The digital workflow permits an increase in the accuracy of surgical and orthodontic setups. The tool that transfers the information is the CAD/CAM (Computer-Aided Design/ Computer-Aided Manufacturing) template. The aim of this review is to illustrate the use of computer-guided surgery in orthodontics regarding miniscrews and piezocision. The search strategy was a combination of Medical Subject Headings (Mesh) and free text words for PubMed. A total of 27 articles were included in this review: 16 concerned miniscrews and 11 concerned corticotomy. The current need for faster treatments, the improved systems of anchorage, and the evolution of imaging technologies require operators to be knowledgeable of the digital workflow. CAD/CAM templates allow greater precision and predictability of miniscrew insertion even if in the hands of less experienced clinicians and permit a better orientation and depth of the cortical incision. In conclusion, digital planning makes surgery faster and easier and allows for the identification and correction of any potential problem before the procedure.

“…Sci. 2023, 13, 7474 2 of 11 Skeletal anchorage in the anterior palate is optimal for supporting various treatment mechanics, including distalization [8], rapid maxillary expansion [9], space closure [10], intrusion mechanics [11], canine disimpaction [12][13][14] and final incisor position relative to the facial profile esthetics [15,16]. Furthermore, orthodontists can address more complex clinical situations, such as severe open bite [17], impacted teeth [18] or mixed dentition [19].…”

At present, temporary anchorage devices (TADs) are continuously gaining importance because of their usability and their possibility to broaden clinical force applications; however, how difficult can their placement planning be? Aim: The aim is to evaluate the association between clinical experience, digital knowledge and the capability of virtual planning in palatal orthodontic miniscrew insertion in various types of clinicians, divided by different levels of experience. Methods: A total of 30 participants (10 dental students, 10 orthodontics students and 10 orthodontists) with different levels of clinical and digital experience were randomly recruited in this cross-sectional study. All participants performed a pre-test survey followed by two consecutive digital planning tests and, finally a post-test survey. The digital planning test was made using software BlueSkyBio-BlueSkyPlan, a surgical guide module. The differences in terms of planning execution time, miniscrew insertion and surgical guide realization were evaluated. The Kruskal–Wallis and Mann–Whitney U-tests were performed to determine the effects of independent variables and interactions between groups. Results: The relation between clinical experience and bicorticalism was statistically significant (p = 0.017); in the planning execution time, a significant difference was evident between the dental students and the orthodontics students (T1: p = 0.015 and T2: p = 0.019), who, having good digital knowledge, took an average of 4.58 min less in T1 (p = 0.025), while this difference was significantly reduced in T2 (p = 0.106). Conclusion: Clinical experience increased miniscrew placement accuracy and digital knowledge reduced execution planning time but both had a stronger impact in the first test than in the second.

Maxillary canine impaction is an increasing dental anomaly and is often related to other dento-skeletal anomalies. The aim of this work is to support the clinician in evaluating the relationship between a displaced maxillary canine and clinical (the features of lateral incisors)/skeletal (ponticulus posticus and sella turcica bridging) anomalies through orthopanoramic radiographs, lateral cephalograms, and plaster casts to identify the parameters that best predict maxillary canine impaction. A retrospective observational study was carried out on the analysis of the medical records, radiographic findings (panoramic radiographs and lateral cephalograms), and plaster casts of 203 orthodontic patients divided into a case group, with at least one impacted maxillary canine, and a control group, without an impaction. A chi-square test and logistic regression analysis were used to analyze the data. A statistically significant association was found between the impaction of the maxillary canine and the female sex, the bridging of the sella turcica, the ponticulus posticus calcification, and the anomaly of the lateral incisor; a logistic regression revealed that these significant variables were found to be positive predictors of impacted maxillary canines, particularly in reference to the impaction in the palatal area. Finding one of these clinical and radiographic elements can represent a predictive sign of the possible impaction of the maxillary canine.
