Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Objectives: Cone beam computed tomography (CBCT) is routinely used to measure alveolar bone dimensions. This study investigated factors likely affecting the accuracy of such measurements. Methods: Marker holes, apical to maxillary and mandibular molar roots, and mesio-distal molar occlusal reference grooves were created in fresh pig heads (n=26 quadrants), followed by CBCT scans at 0.4 and 0.2 mm voxel sizes before and after soft tissue removal. Subsequently, bucco-lingual sections bisecting the marker holes were cut, from which physical alveolar bone height and thickness were measured. Two blinded raters, using Dolphin 3D and OsiriX software, independently collected alveolar bone height measurements from CBCT images. Differences between CBCT and physical measurements (DCBCT-Phy) were calculated. The mean DCBCT-Phy and limit of agreement (LOA, ±1.96SD) for each factor were depicted by Bland-Altman methods. The influence of each factor was examined by repeated measures ANOVAs. Results: The rater factor affected the mean CBCT measurements in both jaws, with mean DCBCT-Phy from a more-experienced rater significantly (p0.05) closer to "0" than from a less-experienced rater, while their LOA ranges were similar (Maxilla, 0.17mm±2.09mm vs.-0.48mm±2.02mm; Mandible, 0.01mm±1.04mm vs.-0.70mm±1.21mm). The software factor also affected the mean CBCT measurements in both jaws, with mean DCBCT-Phy from Osirix significantly (p

Abstract: Background: The width of the facial alveolar bone wall is crucial for long term successful esthetic outcomes of implants immediately placed into extraction sockets. A threshold of 2 mm is recommended to minimize buccal vertical bone resorption. Aim: To assess the width of the facial alveolar bone wall using cone-beam computed tomography images (CBCT). Methods: Retrospective CBCT images were acquired from a representative sample of Asians using the i-CAT(R) classic system with a 0.4 mm voxel size. At random, 200 CBCT images were selected according to predefined criteria. The DICOM file was imported into the i-Cat Vision(R) software. In the panoramic screen, the middle of each tooth was selected and, in the sagittal window, the middle cross section was selected for performing the measurements using a computer. The vertical distance from the alveolar crest (BC) - CEJ was measured. The width of the facial alveolar bone wall was measured at three locations: 1, 3, and 5 mm apical to BC. Descriptive statistics, frequency analyses, and multi-level comparisons were performed. Results: The sample consisted of 74 males and 126 females (mean age of 37.2 years; range 17-82 years). A total of 3618 teeth were assessed. There was no significant difference between the values of right and left sides, or between genders. However, statistically significant differences were observed between age groups at all levels. The distance from CEJ-BC varied from 0.4 to 4mm, with an overall tendency to increase with age. The mean width of the facial alveolar bone wall at anterior teeth was 0.9 mm and increased towards posterior regions. Rarely, a width of 2 mm was yielded (0.6-1.8 % for anterior teeth, 0.7- 30.8 % for posterior teeth). At a 5mm distance from BC, minimal widths of facial alveolar bone were identified for the anterior teeth. The frequency of dehiscence ranged from 9.9- 51.6 % for anterior and 3.1- 53.6 % for posterior teeth, respectively. Conclusion and clinical implications: A thin facial alveolar bone wall was usually present in both jaws. Hence, for most patients, adjunctive bone augmentation may be needed when installing implants in areas of esthetic concern.

Available in PDF, EPUB and Kindle. Book excerpt: Since its introduction to dentistry, cone beam computed tomography (CBCT) has undergone a rapid evolution and considerable integration into orthodontics. However, despite the increasing popularity of CBCT and progress in applying it to clinical orthodontics, the profession has lacked a cohesive, comprehensive and objective reference that provides clinicians with the background needed to utilize this technology optimally for treating their patients. Cone Beam Computed Tomography in Orthodontics provides timely, impartial, and state-of-the-art information on the indications and protocols for CBCT imaging in orthodontics, clinical insights gained from these images, and innovations driven by these insights. As such, it is the most current and authoritative textbook on CBCT in orthodontics. Cone Beam Computed Tomography in Orthodontics is organized to progress sequentially through specific topics so as to build the knowledgebase logically in this important and rapidly evolving field. Part I provides the foundational information on CBCT technology, including radiation exposure and risks, and future evolutions in computed tomography. Part II presents the Principles and Protocols for CBCT Imaging in Orthodontics, focusing on developing evidence-based criteria for CBCT imaging, the medico-legal implications of CBCT to the professional and the protocols and integration of this technology in orthodontic practice. Part III provides critical information on CBCT-based Diagnosis and Treatment Planning that includes how to interpret CBCT scans, identify incidental pathologies and the possible other uses of this technology. Part IV covers practical aspects of CBCT’s Clinical Applications and Treatment Outcomes that encompasses a range of topics, including root morphology and position, treatment of impacted teeth, virtual surgical treatment planning and outcomes, and more.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Currently, the correct study of the alveolar bone morphology crucial and important factor in immediate implants . Since the introduction of the cone beam tomography (CBCT) it has developed into an essential diagnosis exam for adequate treatment planning, while also being a useful complementary exam due to the amount of data that a three-dimensional image provides to the dental clinician.Objective: to examine CBCT images by measuring four bone morphologic characteristics around maxillary teeth.Materials and methods:The present retrospective study included CBCTs (Planmeca ProMax 3D) obtained using a spiral technique with 0,2 mm thickness (200 mm field of view (FOV), 90 kV, 10 mAs, 1 mm pass) from patients referred to the department Of Periodontology of the Dental School of Seville (Spain) from January to December 2014. The size of the sample are 49 CBCT, with 208 teeth, 19 men and 30 women with an age range of 40,3 years (22-71). Radiographic image analysis or CBCT evaluation: Three calibrated examiners made distinct measurements of the bone relative to the tooth in question.. Data was reconstructed with an DICOM image.Parameters:1. The thickness of the facial bone wall was measured in a sagittal slice, perpendicular to the long axis of the root at several heights:A: thickness at the coronal part of the facial crestB: thickness at 4 mm from the coronal facial crestC: thickness at the apex from the apical constriction to facial wall D: the palatal thickness perpendicular to the coronal crest, near to buccal point A.2. Apical anchorage: a line from the most coronal point where implant bone preparation would start up to an anatomical (bone partitions, nerve paths ...) that is perpendicular to the bisector of the remaining alveolus.3. Alveolus width: a line from the vestibular crest to the palatal crest in the coronal portion, closest to the LAC.4. Differences from the palatal height with respect to the vestibular: once traced the axial axis of the tooth, a perpendicular line that passes through the vestibular crest is drawn. The distance between the perpendicular line and the ridge on the palatine is measured by drawing a line that is in turn, parallel to the axial axis of the tooth.Results and Discussion:In the upper jaw, the 89,4% of incisors, the 93.94% of canines, 78% of premolars and 70,5% of molars had a thickness inferior to the ideal 2 mm of buccal alveolar process as in other studies like Huynh-Ba 2010. Recent studies of the alveolar width by Zang 2015, found similar results for central incisors, lateral and canines (9,55-8,30-9,62). Our mean values are between 7,8-11,9 from incisor to molars. In the Nishihara et al 2017 study they find mean values of 9,4 u00b1 1,1mm for 1u00ba PM and 11,0 u00b1 0,6mm for 2u00ba PM. The anterior zone is the best place to insert a immediate implant in terms of apical anchorage, while the mean values of buccal thickness advice against these locations. The difference between vestibular and palatal crest tends to increase in premolars and molars sites, this means, from a clinical perspective, that the implant can be exposed during healing if it was not submerged at least 1-2 mm. The thickness of the palatal bone in mean values are higher than in vestibular, so this seems to be an ideal zone to achieve stability and insertion torque when placing an immediate implant.Conclusions:The alveolar bone thickness of the buccal plate was observed as thinner than 2 mm in the upper jaw, but only in canines for the palatal plate. Apical anchorage for immediate implant could be possible in anterior teeth. The mean values of alveolar width increase from anterior to posterior teeth.
