To improve accessibility and facilitate the procedure for clinicians, a guided approach for TAD insertion in the palatal vault, using insertion guides, has become increasingly prevalent. The manuscript primarily focuses on the real advantages and possible disadvantages that clinicians can expect when using insertion guides during TAD insertion into the palatal vault. Safety, precise evaluation of insertion depth, and the potential to execute a \"one-visit protocol\" are examined. Indeed, both direct and indirect palatal insertion protocols result to be efficient and safe in daily practice. The use of insertion guides result to be particularly beneficial for less experienced clinicians as well as for more complex patients and impacted teeth cases. Insertion guides can be created overlapping intraoral scanning to cbct or also to lateral teleradiograph, with sufficient accuracy and lower radiation exposure. However this method is limited in achieving bicortical evaluation, as well as relations to incisive canal and nasal floor. Finally a case report is presented, describing a full digital orthodontic treatment of a young adult patient presenting narrow maxilla. Slow maxillary expansion and fixed orthodontic treatment are described.</div></div>","PeriodicalId":48688,"journal":{"name":"Seminars in Orthodontics","volume":"31 1","pages":"Pages 91-97"},"PeriodicalIF":2.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141408842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of DPAs entails several advantages including increased efficiency of tooth movements due to customized pressure points or zones, a better fit and precision of the clear aligners as well as the ability to produce a wide range of different removable orthodontic appliances in-office.

In particular, the vast variety of possible custom-design DPAs poses the risk of exposing patients to cytotoxic materials.

Charles J. Burstone pioneered a three-dimensional (3D) approach in orthodontics, advocating for a shift beyond appliance-focused methods. Initially, biomechanics studies were constrained to two-dimensional (2D) analysis due to the complexities of 3D evaluation. Despite progress in computational tools and digital modeling, orthodontic biomechanics has largely maintained a 2D orientation. This paper advances orthodontic biomechanics into 3D, re-evaluating concepts previously limited to 2D frameworks. A dedicated software, DDP-Ortho (Ortolab, Poland), is introduced to enable orthodontists to analyze and resolve biomechanical challenges in 3D, facilitating appliance designs with precise 3D force systems. The representation and calculation of force vectors and moments in 3D are detailed, emphasizing the inherent complexity absent computational support. Key processes such as vector subtraction and addition, fundamental for assessing and refining orthodontic force systems, are explained. Additionally, the vector split (couple replacement) method, previously described in 2D, is extended to 3D, addressing the unique constraints and challenges of this approach. These tools promise to refine the accuracy and effectiveness of orthodontic treatments, setting the stage to examine the interactions between 3D force systems and dental movement, which will be addressed in a subsequent paper, to broaden the potential of contemporary orthodontic therapy.</div></div>","PeriodicalId":48688,"journal":{"name":"Seminars in Orthodontics","volume":"31 1","pages":"Pages 150-157"},"PeriodicalIF":2.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143134070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process demands the creation of mental models of the impaction and resolving it either by envisioning the canine's movement to its correct position or considering its removal.

Experts and intervention group novices had the 3D simulator in addition to standardized patient records. Their responses were recorded and analyzed according to a coding scheme reflecting the clinical reasoning process.
