“…[10] Radiographic signs, detectable on the panoramic radiography that indicate the presence of a close relationship between the inferior alveolar nerve and the lower third molar are [11,12]: -Radiotrasparent band darkening the root of the third molar because of the decreasing of bone density produced by the mandibular canal crossing the area. -Interruption of the line marking the roof of the canal due to the root of the third molar crossing it.…”

“…[18] CT examination should be used only for patients in whom panoramic radiography shows one or more of the radiographic signs indicating an intimate relationship between the mandibular canal and the third molar root, but this relationship cannot be defined sufficiently using conventional radiology. [12,15,19,20] Thereby, it may substantially contribute on the planning of the surgical approach and on the evaluation of consequences and results. [16] CBCT gives undistorted three-dimensional images with a very good resolution that allows visualization of anatomical structures shape and their real size.…”

Introduction: The imaging method of cone beam is an improved, extremely accurate computed tomography applicable in the whole field of dentistry. Due to its ability to locate the exact position of the impacted teeth, CBCT software has an important role in the management of difficult cases of impacted third molar. In some situations, the lower third molar is quite near to the inferior alveolar nerve that the surgical extraction can present a high risk of post-operative sensitive impairs of the skin and mucosa of the lower lip and chin on the same side. Presentation of case series: Our study tried to assess the contribution of CBCT in the pre-operative evaluation and further treatment of patients with impacted third molars in mandibular bone with high risk of inferior alveolar nerve injury. The paper presents three clinical cases showing positive signs on standard OPG, which exhibit indicators of a potential contact between the inferior alveolar nerve and the impacted lower third molars. For an improved exploration Dental CT Scan, DICOM image acquisition program, and 3D reconstruction with a special software were used. Conclusions: The study showed that compared with panoramic radiography, CBCT improve the evaluation of the surgical risk and allow a more accurate planning of surgery.

“…6 The patient must also be aware that there is a risk of early and late infection that will necessitate the removal of the roots, which in most cases occurs once control study and one retrospective study. [6][7][8][9][10][11][12][13] Three of the six articles investigate the fate of third molars deemed at high risk on a DPT radiograph that have been coronected. [7][8][9] The remaining three articles compare the techniques of coronectomy versus complete removal of the high risk third molar tooth.…”

“…The introduction and development of 3D software, scanning and print techniques enable the visualization and creation of virtual and real anatomical models which give students the opportunity to learn anatomy in detail and train for dental procedures as many times as necessary (Friedland et al, 2008). Additionally, with on-going developments in technology and the increasing availability and use of computer products such as smartphones, tablets and e-books, contemporary students are well acquainted with the use of computer technology in everyday life (de Boer et al, 2015).…”

CANTÍN, M.; MUÑOZ, M. & OLATE, S.Generation of 3D tooth models based on three-dimensional scanning to study the morphology of permanent teeth. Int. J. Morphol., 33(2):782-787, 2015. SUMMARY:The dental student should have thorough knowledge of the dental morphology and develop adequate manual skill to reproduce any part of the tooth, thus maintaining the perfect correlation with associated structures. Computers are becoming an integral part of dental education and dental practice, especially for the acquisition of information in three dimensions and the production of solid objects from computer models. The aim was to present educational material that would allow the dental student to learn to easily identify the morphologic characteristics of permanent teeth, using new technological tools. In order to do this, healthy permanent teeth were scanning by NextEngine™ 3D Scanner HD using the MultiDrive. A 360° scan in macro range was chosen in each case. The number of scans for this family was 16, due to surface irregularities that require readings from a greater number of angles. Volumes of external structures of the scanned tooth were generated and stored in *.STL files. Virtual models were transferred in to programs used for producing physical prototypes that faithfully reproduce anatomy of interest using ReplicatorG software and MBot Grid II 3D printer. 3D virtual and printed macro models of permanent teeth were obtained. This models allows an excellent visualization of the morphological characteristics of permanent teeth. 3D virtual and printed teeth, derived from real tooth, are intended to be a valuable learning tool that can be used in addition to or instead of extracted teeth and they are anticipated to represent an improvement over plastic teeth.
