This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Statement of Problem: The anterior mandible has conventionally been deemed as a relatively â€safe zone†for dental implants due to perceived lack of innervation to the area as well as its relatively thick cortices and dense bone. However, with the evolution of cone beam computed tomography (CBCT), a number of anatomic challenges have been identified by clinicians that can lead to neuropathy and life-threatening hemorrhage if violated. The three critical anatomic structures in this area that pertain to implant placement are the sublingual artery (SLA), submental artery (SMA), and the mandibular incisive canal. Currently, there is a lack of knowledge regarding average measurements of these anatomic structures in relation to a specific non-variable landmark. Furthermore, it is not known if there are any significant variations of these anatomic structures in dentate and edentulous patients. While these structures may be identifiable on a CBCT scan, mandatory CBCTs are not required by practitioners in order to perform implant surgery in the anterior mandible. Purpose: To determine if standardized average values can be obtained for the sublingual artery (SLA), submental artery (SMA), and mandibular incisive canal (MIC), and if differences exist between dentate and edentulous patients. Materials and Methods: CBCTs of 125 edentulous and 100 dentate subjects were evaluated at the anterior mandible for incidence of visualization of the SLA, SMA, and MIC. Measurements of these three structures were also made from the inferior cortical border of the mandible to the superior border of each structure in order to gain average anatomical measurements. The cross-sectional shapes of anterior mandibles were also categorized and prevalence of each shape in this sample was calculated. Results: The incidence of visualization of the SLA on CBCT was found to be 100% for edentulous subjects and 98% for dentate subjects. The SLA was located approximately 15mm above the inferior border of the mandible. The incidence of visualization of the SMA on CBCT was 94% for edentulous subjects and 88% for dentate subjects. The SMA was located approximately 5mm above the inferior border of the mandible. The incidence of visualization of the MIC on CBCT was 61% for edentulous subjects and 59% for dentate subjects. The MIC was found to be approximately 1.5mm in diameter at the lateral incisor and canine regions. The MIC was located approximately 11mm above the inferior border of the mandible in edentulous patients, and approximately 14mm above the inferior border of the mandible in dentate patients. The edentulous mandibular ridge attained a buccal-lingual width of 6 mm at a mean distance of 4 mm below the ridge crest in this patient sample. A new classification system for the cross-sectional morphology of the anterior mandible was characterized and includes the following shapes: hourglass, ovoid, pear, sickle, and triangular. The pear was the most commonly visualized cross-sectional morphology among both edentulous and dentate patients. Conclusions: The sublingual artery and submental artery can be consistently identified in the anterior mandible using CBCT, both in dentate and edentulous patients. The SLA was located approximately 15mm above the inferior border of the mandible and the SMA was located approximately 5mm above the inferior border of the mandible. The mandibular incisive canal was not consistently visualized. The cross-sectional morphology of the anterior mandible is diverse in dentate and edentulous mandibles with pear shape being the most common in both situations. These findings should be taken into consideration when treatment planning for implants using CBCT or panoramic radiography.

Book excerpt: The fine osteological and radiological anatomy involved in dental and oral surgery has progressed greatly in recent years, especially in the field of dental implants. In dental implant surgery, the maxilla and mandible are the operative fields. The frequent complications of dental implants on the maxilla are bleeding and iatrogenic maxillary sinusitis, but these are less likely to be life-threatening injuries. However, dental implant surgery of the mandible can lead to serious complications such as mental nerve paresthesia and airway obstruction due to hematoma. Therefore, knowledge of anatomical structures relevant to the mandible is significant, and the authors have a long history of investigating normal anatomy and anatomical variations of the mandible. When the dentist needs a comprehensive photographic review of the anatomy focusing on the mandible, including well-described anatomy and rarely shown variations with both gross and radiologic observations, this book will prove to be a valuable resource that is useful for surgery. It is the first book of its kind devoted to the osteological and radiological anatomy of the mandible for dentists and oral surgeons. It will satisfy the growing demand in the field of surgery and education and will be welcomed and timely for clinicians and trainees in the field. It will be of benefit to general dentists, dental students, and specialists and residents of periodontics, dental implant, prosthodontics, and oral surgery, as well as craniofacial surgeons, anatomists, plastic surgeons, ENT surgeons, head and neck surgeons, medical students, dental hygienists, anthropologists, and forensic specialists.

Download or read book Three dimensional Surface Changes in the Mandible During Growth and Development written by Bryon Joseph Viechnicki and published by . This book was released on 2011 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional analysis of mandibular growth provides the potential for pedodontists, orthodontists and surgeons to prescribe treatment that works in harmony with the individual growth of the patient. Despite efforts by 3D pioneers, the visualization of growth and development remains reminiscent of the landmark-based cephalometric analyses used in two-dimensional studies. The objective of this study was to identify 3D topographical changes of the mandible during growth and development of adolescent orthodontic patients. Nine pairs of pre- and post-orthodontic cone-beam computed tomography (CBCT) scans were used to generate mandibular surfaces. Surfaces were superimposed on trabecular bone in the anterior mandible using a mutual information algorithm, and topographical changes were visualized and quantified. The intra- and inter-rater intraclass correlation coefficients for surface generation (0.94 and 0.93, respectively) and superimposition (0.96 and 0.82, respectively) demonstrate the reliability of the techniques. The findings of this study support the theories of bone remodeling reported in histological, implant-based, and landmark studies of mandibular growth.

This book was released on 2009 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background. The intraoral findings of patients presenting with differing lower anterior face heights are variable.Methods. Upper anterior face height over lower anterior face height ratios were established from 111 pretreatment iCATRTM CBCT scans and analyzed with AMIRARTM imaging software. Maxillary and mandibular central incisor and first molar vertical heights and buccolingual inclinations were measured relative to fixed reference planes. Mean differences between the groups were assessed using an analysis of variance.Results. Clinically significant differences in dentoalveolar heights, but not buccolingual inclinations, between the face height groups were found.Conclusions. Face height and dentoalveolar position can be determined using CBCT image data. Vertical height, not buccolingual inclination, is associated with differences in lower anterior face height.Objective. To analyze the pre-treatment cone beam computed tomography (CBCT) records of orthodontic patients for determination of dentoalveolar positional differences in subjects classified into three groups: long, normal and short lower anterior face height.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: IntroductionDevelopment of CBCT has enabled more precise diagnostics before dental implant insertion in the area of maxilla and mandible. The prevalence of cone beam computed tomography (CBCT) has allowed visualizing very detailed anatomical structures, which are less visible by means of classical RTG projections. Mandibular incisive canal (canalis alveolaris anterior inferior) is one of them. Aim The aim of the study is a radiometric evaluation of the occurrence of mandibular incisive canal and its dimensions. Materials and Methods One hundred scans of CBCT performed in the Department of Oral Surgery at the Medical University of Warsaw were analyzed. Tomography images of 55 women and 45 men were examined. The frequency of occurrence, symmetry, the length of the canal, dimensions forward to the mental foramen, minimal distance to the root apices and minimal distance to the alveolar edge were assessed. Results The analysis has revealed the frequency of the occurrence exceeding 85%. Furthermore, the wide variety of topography and its dimensions was revealed. The length of the canal differs significantly from 1.6 mm to 30.5 mm (SD = 6.36). Although the topography is also changeable, it is generally running by the vestibular dense lamina of the body of mandible and approximating to the lingual side. The lack of symmetry is also noticeable. In some cases it is possible to detect only one mandibular incisive canal u2013 left or right (8% of cases). Conclusions and Clinical implications Radiometric evaluation revealed considerable variety of the anatomy of mandibular incisive canal, both dimensions and symmetry as well as topography. Due to the substantial frequency of appearance of mandibular incisive canal, thorough diagnostics for implantation procedures in the lower anterior mandible and bone grafting from this region is recommended. Scrupulous diagnostics by means of CBCT allows avoiding threatening periprocedural and post-procedural complications.

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: The dentogengival unit (DGU) can be defined as the anatomical complex formed by the gingival membrane, gingival sulcus, junctional epithelium and connective tissue insertion, also known as the u201cbiological spaceu201d. It is very important, and its invasion may cause the collapse and apical migration of the fixation apparatus. In this study a CBCT of the anterior maxilla of each of the 20 participants was done with Planmeca ProMaxu00ae 3D MID and 9 variables were analyzed. According to the evaluation of the preliminary sample, we concluded that the CBCT allows measurements with high precision, without bias of subjectivity or necessity of invasion. It is, therefore, a method with high efficacy and low intolerance.
