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.

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.

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

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: AIM: Extraction of a tooth can lead to alveolar ridge resorption which can be minimized by socket preservation. The aim of this study is to analyze vertical and horizontal alveolar ridge dimensions clinically and by CBCT immediately following extraction and 3-4 months following socket preservation. METHODS: The preserved group (P) consisted of 20 patients with1-2 non-molar teeth requiring extraction with socket preservation, while the control group (C) consisted of 5 patients requiring extraction alone. An acrylic stent was fabricated presurgically in order to measure vertical and horizontal ridge dimensions clinically and radiographically immediately following extraction and 3-4 months following socket preservation. RESULTS: Overall, P sites gained ridge height and lost minimal ridge width over 3-4 months, while C sites lost both ridge height and width. Preserved sites in which the teeth were extracted due to caries had the most significant gain in the radiographic vertical occlusal dimension (RVO). Overall, high correlations were found between the clinical and radiographic measurements at the initial surgery and at the 3-4 month follow up. CONCLUSIONS: The preserved group had minimal ridge resorption and more socket bony fill when compared to the non-preserved group 3-4 months following tooth extraction, especially when the tooth was extracted due to caries. Additionally, the CBCT can be a useful diagnostic tool to evaluate socket preservation healing, as it compares well to clinical assessments of socket healing.
