(1) Background: Computer-guided surgery is now established as the main technique for implant placement, reducing intraoperative complications and helping the clinician avoid damaging sensitive anatomical structures, such as, for example, the maxillary sinus. (2) Methods: A complex case is discussed to suggest how computer-aided surgery can merge with freehand surgery, as a surgical guide can make a freehand surgical procedure less complicated and more predictable. (3) Results: A surgical procedure was executed following digital planning, except for sites 1.5 and 2.5, where a mixed approach was adopted: they were initially prepared with a milling depth of 1 mm from the base of the maxillary sinus and were then finished using osteotomes, according to the technique described by Summers. Radiography confirmed the correct positioning of the implants and the sinus lift. (4) Conclusions: A mixed digital/analogical approach used in complex cases increases the accuracy of the results and reduces complications and treatment time. The presence of a correctly digitally planned surgical guide helps in the freehand approach and not only in the digital approach.

Introduction: Thanks to the great development of digital technology, viaCAD (computer-aided design) and CAM (computer-aided manufacturing) systems, digital models canbe used as an aid for orthodontic planning decision-making processes as there are numerous studies in the literature that support the validity ofthe digital model measurements of anterior teeth and the total coefficient of Bolton analysis. The aim of the present study isto compare the average length value of the current upper and lower arches with that of a hypothetical nickel–titanium wire and to confirm the reliability and accuracy of digitally taken measurements of the anterior and total Bolton coefficients.In this retrospective study, dental casts of 138 Caucasian adolescent patients were scanned with an extraoral scanner, and Ortho3Shape software was adopted for the following dental cast measurements: actual and ideal lengths of the lower arches and anterior and total Bolton coefficients.In the present study, we found that the mean value of the anterior coefficients of the Bolton index was compatible with those of previous studies, confirming the reliability of digital measurements.Therefore, digital CAD/CAM models may be a viable alternative to plaster models, as they can facilitate model preservation and recovery. For future studies, it would be better to use intraoral scanners (IOSs) to ensure greater accuracy, since they only require one step and allow obtaining better results for the patients.

“…At present, most dental technicians still use the more complex human-computer interactive planning method (Motohashi et al 1999;Nota et al 2022), which usually takes an average of 30 minutes to complete a patient's orthodontic plan design. Over the recent years, some studies on orthodontic path planning have been taken, and these methods have addressed some issues.…”

Automatic tooth arrangement and path planning plays an essential role in computer-aided orthodontic treatment. However, state-of-the-art methods have some shortcomings: low efficiency, excessive cost of displacements or collisions and insufficient accuracy. To address these issues, this paper proposes an innovative orthodontic path planning method based on the improved gray wolf optimization algorithm, which is called OPP-IGWO. First, the tooth model is preprocessed to obtain initial pose in which each tooth is segmented and built up with an oriented bounding box (OBB). Next, the target pose of each tooth is determined through the ideal dental arch curve and the optimal jaw principle. Finally, the path from the initial pose to the target pose of each tooth is planned based on IGWO, which is improved mainly from three aspects: (1) The greedy idea is adopted to initialize the gray wolf population based on dental interpolation. (2) The linear convergence factor in the traditional gray wolf optimization algorithm (GWO) is replaced with a non-linear convergence factor. (3) We propose a position update strategy based on a dynamic weighting approach, which introduces a learning rate for each gray wolf. The experimental results show that our OPP-IGWO method outperforms the state-of-the-art methods. Compared with improved genetic algorithm (IGA), normal simplified mean particle swarm optimization algorithm (NSMPSO), multiparticle improved swarm optimization (Mutil-IPSO) and improved artificial bee colony algorithm (IABC), the OPP-IGWO has an improvement on performance by 14.22%, 11.46%, 6.32% and 5.27% respectively.
