“…Various radiographs are used, including periapical, occlusal, and panoramic radiographs, but the information obtained from these images is two dimensional. [ 14 , 15 ] The disadvantages of these methods are anatomical superimposition and distortion of images. As a result, there is a possibility of damage to the neurovascular bundles and perforation of the maxillary sinus membrane.…”

Introduction: Sinus lift surgery allows sufficient volume of bone to be created in the posterior part of the maxilla. The aim of this study was to investigate the changes in maxillary sinus volume after a sinus lift and the rate of increase in ridge height at the site of the graft. Methods: Eleven patients were chosen for sinus lift from among those who were referred to the radiology department for implant placement in the posterior region of the maxilla and whose bone height at the posterior of the maxilla was less than 4 mm on the cone-beam computed tomography (CBCT) image. The sinus volume was measured after importing the CBCT file in DICOM format into Mimics software. After determining the sinus volume, the patients underwent sinus lift surgery, and the amount of material used during the surgery was measured. After the time required to repair the area, the CBCT image was taken again. Then, the changes in the volume of the maxillary sinus and the increase in the height of the maxillary ridge at the surgical site were calculated. Then, the second stage of the surgery was performed to place the implant at the implant site. Results: For an average of 1.40 cm3 of material, the rate of increase in ridge height was 10.52 mm, and the average change in sinus volume was 1.19 cm3. Conclusions: CBCT images and Mimics software have many applications in examining and predicting parameters before and after sinus lift surgery.

“…9,20 CBCT's offer fast volumes acquisition (10 -80s), lower radiation doses when compared to CT's, high spatial resolution, dimensional accuracy, cheaper unit cost (compared to CT), usually provided with more user-friendly and dentally-oriented software especially when used during implant planning, and the ability to limit the field of view to the region of interest for example just the potential implant site. 9,21,22 It is worth mentioning that variations in some advantages, volume qualities, and radiation doses of different x-ray machines do exist. 20 CBCT is advantageous in potential implant site assessment as it provides comprehensive anatomical details allowing accurate surgical planning and possible integration with guided surgical techniques.…”

“…[46][47][48] Bone quality is not only confined to the density or the mineral content, but includes aspects like the internal architecture of the bone, the alignment of the trabeculae, and matrix-related properties. 21,48 In CT scans, the tissue densities are represented in Hounsfield units (HU) that are considered a reliable measure to assess the bone density at the candidate implant sites. 5,[49][50][51] In CBCT volumes, the evidence on the reliability of using CBCT gray values for assessment of bone density is uncertain particularly since these values are not absolute as compared to the CT's HU.…”

“…52,61 An obstacle is the absence of a standard scaling system among the CBCT manufacturers to standardize these gray values, consequently, the interpretation and comparison of these values acquired from different CBCT units will be difficult and impractical in certain instances. 21,61 The resultant CBCT gray values are greatly influenced by the exposure parameters, machine specifications, and object positions within the x-ray units. 57 Imaging during this phase of treatment i.e.…”

The introduction of digital x-ray receivers which replaced conventional films was a significant radiographic development that is commonly used in daily dental practice. Dental implant therapy (DIT) is a sought after dental therapeutic intervention and dental radiography is an essential component contributing to the success of treatment. Dental radiographs taken in daily practice are generally conventional two-dimensional images and/or three-dimensional images. Ideally, the choice of radiographic technique should be determined after a thorough clinical examination and comprehensive consideration of the advantages, indications, and drawbacks. Digital three-dimensional modalities that have emerged over the last decade have been incorporated into DIT with the assumption that treatment outcomes will be improved. These modalities are constantly being reassessed and improved but there is a paucity of published information regarding the assessment of variables such as dosages and dimensional accuracy, suggesting that further research in these matters is necessary. This is crucial in order to obtain evidence-based information that may influence future radiographic practices. In this narrative, the authors present the most commonly used dental radiographic modalities currently used in DIT.

Implant treatment is one of the most important surgical processes in teeth which reduces the difficulties in teeth by providing the interface between bone and jaw. The established implant treatment used to support the denture, bridge and teeth crown. Even though it supports many dental related activities, the successive measure of implant treatment is fail to manage because it fully depends on the patient's personal activities and health condition of mouth tissues. So, the successive rate of implant treatment process is identified by applying the memetic search optimization along with Genetic scale recurrent neural network method. The introduced method analyzes the patient characteristics which helps to recognize the successive and failure rate of implant treatment process. The quality of the implant treatment of using simulation results in terms of sensitivity, specificity and accuracy metrics.
