“…Further advantages derive from its combined use with digital technologies. In recent years, computer-guided surgery using piezoelectric devices has been proposed for a variety of applications, including minor [28,[41][42][43][44] and major orthognathic surgery [45][46][47], extractions [29,31], endodontic surgery [34,48,49], and mandibular lesion resection [26,50], as well as cranial vault resection and reconstruction [35]. With regard to the material of the guides, several materials have been employed so far, including titanium [45], polyethylene perephthalate glycol (aka PETG) [47], polymethyl methacrylate (PMMA) [28], and polyamide [33,46], as in the current study.…”

The extraction of mandibular impacted third molars is one of the most common procedures in oral surgery. One of the extraction methods consists of the preparation of a buccal bone lid to obtain access and remove the tooth. This technique aims to reduce bone loss, promote bone healing distal to the second molar, and increase the accessibility to the impacted tooth, particularly in cases of concomitant pathologies or proximity to the mandibular canal. The procedure benefits from the application of 3D printing technologies to produce cutting guides that, combined with piezosurgery, allow deeply impacted third molar extractions with excellent preoperative planning and extreme localisation precision, as well as predictable repositioning and fixation of the bone lid. The objective of this article is to present two clinical cases of the application of the bone lid technique to extract deeply impacted third molars using 3D printed guides with different designs and piezosurgery.

“…3D printed objects, based on 3D imaging scans, designed by 3D virtual planning software and produced using 3D printing processes have been successfully used in prosthodontic, orthodontic, orthognathic, craniofacial, and oral and maxillofacial procedures [29][30][31][32][33][34]. The benefits of 3D printed objects for teaching and management of treatment procedures in these disciplines have been widely reported.…”

The adoption and adaptation of recent advances in digital technology, such as three-dimensional (3D) printed objects and haptic simulators, in dentistry have influenced teaching and/or management of cases involving implant, craniofacial, maxillofacial, orthognathic and periodontal treatments. 3D printed models and guides may help operators plan and tackle complicated non-surgical and surgical endodontic treatment and may aid skill acquisition. Haptic simulators may assist in the development of competency in endodontic procedures through the acquisition of psycho-motor skills. This review explores and discusses the potential applications of 3D printed models and guides, and haptic simulators in the teaching and management of endodontic procedures. An understanding of the pertinent technology related to the production of 3D printed objects and the operation of haptic simulators are also presented.

“…In contrast, PSI can serve not only as a positioning or osteotomy guide but can also be used in osteosynthesis for rigid fixation of the maxillary segment [3,[18][19][20]. Currently, such 3D CAD/CAM-based templates have been widely used for various facial skeleton surgeries including Le Fort I osteotomy, bilateral sagittal split ramus osteotomy, genioplasty, or facial contouring surgery [15,[22][23][24][25][26].…”

Computer-aided design/computer-aided manufacturing (CAD/CAM)-based maxillary templates can transfer a surgical plan accurately only when the template is positioned correctly. Our study aimed to evaluate the positioning accuracy of the CAD/CAM-based template for maxillary orthognathic surgery using dry skulls. After reconstruction of a three-dimensional (3D) virtual skull model, a surface-based surgical template for Le Fort I osteotomy was designed and fabricated using CAD/CAM and 3D printing technology. To determine accuracy, the deviation of the template between the planned and the actual position and the fitness of the template were evaluated. The mean deviation was 0.41 ± 0.30 mm in the medio-lateral direction, 0.55 ± 0.59 mm in the antero-posterior direction, and 0.69 ± 0.59 mm in the supero-inferior direction. The root mean square deviation between the planned and the actual position of the template was 1.21 ± 0.54 mm. With respect to the fitness of the template, the mean distance between the inner surface of the template and the underlying bone surface was 0.76 ± 0.24 mm. CAD/CAM-based templates showed precise positioning and good fitness. These results suggest that surface topography-based CAD-CAM templates can be considered as an alternative solution in replacing the traditional intermediate splints for the transfer of surgical plans.
