The aim of this study is to evaluate the longitudinal transverse growth of the maxillo-mandibular complex in untreated children using the Cone Beam Computed Tomography (CBCT). Two sets of scans on 12 males (mean 8.75 years at T1 and 11.52 years at T2) and 18 females (mean 9.09 years at T1 and 10.80 years at T2) were analyzed using Dolphin 3D imaging. The transverse widths of various maxillary and mandibular skeletal landmarks and the dentoalveolar and dental landmarks at the level of first molars were measured. Overall, there were greater increases in the transverse dimension in the posterior than anterior portions of the maxilla and mandible. The increase in intergonial width of the mandible seems to be primarily due to the lengthening of the mandibular body. The dentoalveolar process at the first molar level increases at an equal rate corono-apically and is independent to the changes in molar inclination. When comparing maxillary dentoalveolar changes with that of the mandible, greater increases were noticed in the maxilla, which might be explained by the presence of sutural growth in the maxilla. Moreover, the first molars maintain their coordination with each other despite the differential increase in the maxillary and mandibular dentoalveolar processes.

Abstract Background The objective of this study was to measure two parameters involved in tri-dimensional implant planning: the position of the buccal and palatal bone wall and the palatal thickness. Methods Cone beam computed tomography (CBCT) images (Planmeca ProMax 3D) of 403 teeth (208 upper teeth and 195 lower teeth) were obtained from 49 patients referred to the Dental School of Seville from January to December 2014. The height difference between the palatal and buccal walls was measured on the most coronal point of both walls. The thickness of the palatal wall was measured 2 mm from the most coronal point of the palatal wall. Results The mean values in the maxilla were 1.7 ± 0.9 mm for central and lateral incisors, 2.2 ± 1.7 mm for canines, 1.6 ± 0.9 mm for premolars and 1.9 ± 1.5 mm for molars. In the lower jaw, the mean values were 1.3 ± 0.8 mm for incisors, 1.7 ± 1.2 mm for canines, 2.3 ± 1.3 mm for premolars, and 2.6 ± 1.7 mm for molars. In the upper jaw, more than 55% of maxillary teeth (excluding second premolars and molars) presented mean height differences greater than 1 mm. In the mandible, more than 60% of incisors showed a buccal bone thickness of 1 mm from the apical to lingual aspect. All teeth except the second premolar presented a buccal wall located more than 1 mm more apically than the lingual bone wall. Conclusions The buccal bone wall is located more apically (greater than 1 mm) than the palatal or lingual table in most of the cases assessed. The thickness of the palatal or lingual table is also less than 2 mm in the maxilla and mandible, except in the upper canines and premolars and the lower molars.

Cone-beam computed tomography (CBCT) is a relatively new modality providing 3D imaging that has become more accessible than ever to dental practice. This brings in new challenges that need to be addressed. This article discusses the role of CBCT in dentistry and highlights the availability of current guidelines.

The purpose of this report is to highlight the histopathologic appearance of the mandibular simple bone cyst (SBC) – a pathologic condition which continues to stay an enigma for a lot of colleagues. Cone-beam computed tomography of a two-chamber SBC (ie, multilocular type) of the mandibular body in a 41-year-old white female is analyzed. Brief literature review is also performed giving the possibility to understand all intraoperative appearances of the SBCs and contemporary techniques of its management.

ABSTRACT Background The evolution of cone beam computed tomo- graphy three-dimensional (CBCT 3D) imaging has dramatically changed the potential for presurgical and pretreatment planning, such that outcomes are more predictable and complications more avoidable. Purpose The purpose of this article was to systematically review scientific and clinical literature pertaining to the uses and benefits of 3D imaging CBCT for diagnosis and treatment planning in Implantology including prosthodontics. Materials and methods Various databases, like PubMed, EBSCOhost and ScienceDirect, were searched from 1998 to 2010 to retrieve articles regarding the clinical applications of CBCT in dentistry. Cone beam computed tomography in dentistry was used as a key phrase to extract relevant articles in dentistry. A manual search for the references from the retrieved articles was also completed. The articles published only in English, randomized clinical trials, prospective and retrospective clinical studies, laboratory and computer-generated research were included.   The search revealed 540 articles of which 447 were irrele- vant to the study and therefore excluded. Results Cone beam computed tomography has created an opportunity for clinicians to acquire the highest quality diagno- stic images with an absorbed dose that is comparable to other dental radiological examinations and less than a conventional CT. Therefore, if placement of an implant might approach a nerve, invade the sinus, or penetrate out of the confines of the jawbone, the patient should be offered a discussion of CBCT 3D imaging. In addition, CBCT 3D patients should be advised of the risks, benefits and alternatives to such treatment, based upon any additional data provided by the imaging.

Lateral Cephalograms

The aim of this longitudinal study was to evaluate the sagittal and vertical growth of the maxillo–mandibular complex in untreated children using orthogonal lateral cephalograms compressed from cone beam computed tomography (CBCT). Two sets of scans, on 12 males (mean 8.75 years at T1, and 11.52 years at T2) and 18 females (mean 9.09 years at T1, and 10.80 years at T2), were analyzed using Dolphin 3D imaging. The displacements of the landmarks and rotations of both jaws relative to the cranial base were measured using the cranial base, and the maxillary and mandibular core lines. From T1 to T2, relative to the cranial base, the nasion, orbitale, A-point, and B-point moved anteriorly and inferiorly. The porion moved posteriorly and inferiorly. The ANB and mandibular plane angle decreased. All but one subject had forward rotation in reference to the cranial base. The maxillary and mandibular superimpositions showed no sagittal change on the A-point and B-point. The U6 and U1 erupted at 0.94 and 1.01 mm/year (males) and 0.82 and 0.95 mm/year (females), respectively. The L6 and L1 erupted at 0.66 and 0.88 mm/year (males), and at 0.41 mm/year for both the L6 and the L1 (females), respectively.
