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.

This book was released on 2013 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The objective of this study was to determine if a difference existed between arch forms created from tooth surfaces, alveolar bone, and overlying soft tissue. Materials and Methods: The sampling population for this study was 18 individuals with a Class I malocclusion, mild crowding, and a CBCT image of good diagnostic quality. The Facial-axis point was chosen to create the arch form from teeth, the Bowman-Kau point was used to establish the arch form from the alveolar bone, and the WALA ridge was used to calculate the soft tissue arch form. A predetermined algorithm was then used to create five separate arch forms per patient. The arch forms were categorized according to shape and then superimposed on each other within an arch and the distance between tooth, bone, and tissue was calculated. Results: For all characteristics of the tooth, bone, and tissue, the calculated distances were significantly different from 0. The distances between tooth and bone were larger for the mandible compared to maxilla (mean 3.30 vs. 2.48, respectively). The larger distances seemed to be located more posteriorly than anteriorly. The distance between tooth and tissue was largest for the second premolar (2.35±1.59), first molar (2.86±0.63), and second molar (3.25±0.87). A significant difference in distance between tooth and bone on both the maxilla and mandible was observed among race but limited to blacks vs. whites. There were no significant differences in distance between the tooth and either bone or tissue in regards to gender and age. Conclusions: The arch form shapes obtained from the teeth, alveolar bone, and soft tissue are highly individual. However, there was a significant positive correlation found between the tooth, alveolar bone, and soft tissue arch forms. The overall distance between tooth and bone was greatest for the mandible compared to maxilla. The largest difference between tooth and bone were found at the canine and second molar in the maxillary arch followed by the first molar, first premolar and then second premolar. In the mandibular arch the largest difference was found at the first and second molars followed by the canine, first premolar, and second premolar.

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: IntroductionTraditional dental implant practice dictates a healing period after tooth extraction, and a second procedure, to place the implants. With the advent of immediate implant placement protocol, fewer surgical procedures and a reduced treatment period was achieved. For immediate implant placement in the mandibular molar region, the quantity of the interradicular bone (IRB), limiting structures like the inferior alveolar nerve and dimensions of the socket affect the overall success rate.AimThe aim of this study was to retrospectively evaluate the alveolar dimensions of the mandibular first molar using cone beam computed tomography (CBCT) for prospective immediate implant placement.Materials and MethodThe material for this retrospective study comprised of CBCT images taken using the same scanning machine (Galileosu00ae, Sirona, Germany) with a standardized patient positioning and exposure factors (0.4 mm Voxel, 120 kVp, 3u20138 mA). The following measurements were done for the permanent mandibular first molar for prospective immediate implant placement u2013 1) The width of buccal (WB) and lingual (WL) bone 2mm apical from the crest 2) The distance from the inferior alveolar nerve to the furcation (IAN-F) in the mid slice 3) The distance from the inferior alveolar nerve to the apex of the mesial (IAN-M) and distal (IAN-D) root 4) The mesio-distal (MD) and bucco-lingual (BL) socket size at the crest level 5) The width of the IRB 2mm (IRB2) and 4mm (IRB4) apical to the furcation, and at the root apex (IRBA) between the mesial and distal root. Descriptive statistical analysis of all data was done at alpha 0.05 (95% confidence intervals).ResultsThe CBCT images of 200 permanent mandibular first molars from 126 patients (83 males, 43 females; mean age 44.2 years) were evaluated. The MD and BL socket size at the crest was 8.77mm and 7.76mm respectively. The WB and WL, that determines the bone fill in the socket, averaged at 0.91mm and 2.92mm respectively, showing a statistically significant difference (p = 0.003). Among the scans evaluated, 48% had WB values 0.5mm. The IRB of the mandibular first molar, which influences the primary stability of the immediate implant, had a mean dimension of 2.12mm, 2.63mm and 4.35mm at IRB2, IRB4 and IRBA respectively. Only 18% of the subjects had an average IRB value 4mm. The IAN-F value averaged at 13.82mm, while the IAN-M and IAN-D values were 4.31mm and 4.61mm respectively, showing no significant difference (p = 0.15). Only 3% of the study population had IAN-F values

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
