“…Results regarding the behavior of alveolar bone remodeling in posterior areas were scanty. However, some studies attested that naturally healing sites that underwent tooth extraction showed a loss in height ranging from 1.4 to 3.6 mm and a reduction in width ranging from 2.3 to 4.5 mm irrespective of tooth site [34][35][36][37]. Some studies suggested that ridge preservation using low resorbing xenograft could considerably limit the amount of horizontal ridge resorption when compared with tooth extraction alone: a difference ranged between the two groups from −3.33 to −2 mm [19,38].…”

Background: The present retrospective analysis aimed to compare two different single tooth extraction surgical approaches in both premolar and molar areas: less traumatic magneto-electrical versus conventional tooth extraction in minimizing the edentulous ridge volume loss. Methods: In the present retrospective control trial, 48 patients who underwent one-tooth extraction, were allocated either to control (28 sites treated with conventional tooth extraction procedures) or test group (20 subjects treated with less traumatic tooth extraction procedures by tooth sectioning and magnetoelectric roots subluxation). Intraoperatively (during tooth extraction surgery just after the subsequent filling of the alveolar socket with the sterile fast re-absorbable gelatin sponge), and then four months later, contours of the sockets were acquired through a laser intra-oral scanner. The digitally superimposed models were converted to dicom (Digital Imaging and Communications in Medicine) format first, then volumetric and area evaluations were performed with a DentaScan tool package. Non-parametric tests were applied with a level of significance set at p < 0.01. Results: significant reductions of anatomical features were observed four months later in all the groups (p-values < 0.001) with volume losses leading to a final alveolar ridge volume of 0.87 ± 0.34 cm3 for atraumatic extractions and 0.66 ± 0.19 cm3 for conventional extractions. No significant differences were registered for outcomes related to the basal surface variables. When just molar tooth were considered, the outcomes relating to volume loss between baseline and four months (ΔV) and its percentage (ΔV%) showed a better behavior in the less traumatic procedure (ΔV = −0.30 ± 0.10 cm3 and ΔV% = −22.3 ± 8.4%) compared to the conventional extractions (ΔV = −0.59 ± 0.10 cm3 and ΔV% = −44.3 ± 5.8%) with p-values < 0.0001. Conclusions: at four months, the less traumatic tooth extraction procedures by tooth sectioning and magnetoelectric root subluxation seemed to be able to better preserve the volume of the alveolar crest (reduction close to 22% with less traumatic extraction in molar sites) when compared to subjects treated with the conventional tooth extraction techniques.

“…Even though different treatments have been attempted to prevent this, studies failed to show a technique that totally compensates that event (Chappuis et al, 2017). The use of grafting biomaterials into extraction sockets has been intensively studied (Botticelli et al, 2004; Vignoletti & Sanz, 2014; Discepoli et al, 2015; Barone et al, 2017; Iorio‐Siciliano et al, 2020). In a recent systematic review with meta‐analysis (Avila‐Ortiz et al, 2019), alveolar ridge preservation (ARP) procedures were found to be effective in limiting physiologic ridge reduction compared to natural healing.…”

Aim To evaluate dimensional changes in the alveolar ridge and bone structure after tooth extraction when L‐PRF or A‐PRF+ was used in comparison to unassisted socket healing. Materials and methods Twenty patients in need of at least three tooth extractions in the aesthetic zone were included. L‐PRF, A‐PRF+ or control was randomly assigned, leaving one empty socket/edentulous site between conditions. CBCT scans were obtained immediately after tooth extraction and after 3 months of healing. Horizontal and vertical dimensional changes of the ridge and socket fill were calculated. Histological and micro‐CT analysis of bone biopsies were used to evaluate post‐surgical bone structural healing. Results Mean horizontal and vertical changes at 1‐mm below the crest (buccal and palatal side) were similar for the three sites (p > 0.05). For the socket fill, L‐PRF (85.2%) and A‐PRF+ (83.8%) showed superior values than the control (67.9%). The histological and radiological analysis reported more newly formed bone for the PRF groups, without any significant differences between both. Conclusions PRF matrices failed to reduce the dimensional changes after multiple tooth extractions in the premaxilla. After 3‐month healing, both PRF matrices showed radiographically a significant superiority for the socket fill. Histologically, they seemed to accelerate new bone formation.

“…Particularly in the presence of accessory canals and due to postextractive ridge resorption, bone quantity could not be sufficient to place an adequate implant without causing nerve injuries. To prevent this risk, a few authors proposed using ridge preservation techniques for both anterior and posterior sites [ 11 , 12 ]. Delivering profound and proper anesthesia is imperative for the success of any surgical procedure, and hence, it is of utmost importance to have a comprehensive knowledge of the appropriate anatomy of accessory canals.…”

“…These accessory canals may contain neurovascular elements, and if they were injured, they could cause intraoperative and postoperative surgical complications [ 32 ]. Although prosthetic restorations with implants are reliable in the medium [ 10 , 11 ] and long term [ 32 ], early complications during the surgical phase can occur due to accessory canals [ 33 ]. Therefore, it will be necessary to make use of a 3D imaging technique to increase accuracy, have a higher resolution, and reduce scan time and radiation dose.…”

Objectives. The objectives of the study include the following: (i) to assess the presence of accessory canals and foramina in the body of the mandible using cone-beam computed tomography (CBCT), (ii) to evaluate the location, number, diameter, and length of accessory canals in the body of the mandible, and (iii) to propose a new classification for mandibular accessory canals based on the location. Methods. A total of 50 (25 males and 25 females) CBCT scans were analyzed in three anatomical planes and three-dimensional (3D) reconstructions for the exact number, location, diameter, and accessory length canals and accessory foramina in the body of the mandible. The statistical analysis used was an independent t -test. Results. Out of 50 CBCT scans, a total of 243 accessory canals and 245 accessory foramina were found. About 53% of accessory canals and foramina were found in males, while 47% were observed in females; 89% were evident in the anterior region, and only 11% were in the posterior region. The majority (64%) of the medial lingual canals had a diameter greater than or equal to 1 mm, while only 32% of accessory canals had a diameter of less than 1 mm ( p < 0.05 ). The mean length of median lingual canals in females was 1.2910 ± 0.2582 mm and 2.6438 ± 0.5288 mm in male subjects. Mandibular accessory canals are classified broadly into anterior and posterior accessory canals, which have further subdivisions. Conclusion. CBCT plays a dynamic role in determining the mandible location of various neurovascular structures, including accessory canals and foramina. Female subjects were observed with more accessory canals and foramina and more common in the anterior region than in the posterior region.
