“…Panoramic radiographs have been used widely as a diagnostic imaging technique; however, accurate evaluation of hard tissue morphology and density is difficult because of the variable degree of distortions, in addition to the lack of information about buccolingual cross-section dimension or the inclination of the alveolar ridge [2]. The international congress of oral implantologists 2012, supported the use of CBCT in dental implant treatment planning [14].…”

“…Comprehensive patient care and efficient implant planning relies on the use of appropriate dental radiographs and the capability to interpret radiographic findings. Successful implants placement requires recognition of adjacent structures thus permitting sufficient bone interface between implant fixtures and vital structures [1,2].…”

“…Radiographic techniques available for the evaluation of dental implant patients are either plain 2-dimentional projections as dental panoramic radiographs and occlusal views, or a more advanced reformatted cross-sectional three dimensional [3D] imaging techniques as the computed tomography [CT], and cone bean computerized tomography [CBCT] [2].…”

This study aimed to assess attitude and knowledge of sixth year dental students and interns towards panorama and CBCT, and to compare responses relative to level of study and gender. Web-based questionnaire comprising of four sections was used. First, participants provided demographic information. Second, ten close ended questions about panoramic radiography in personal practice and general information of CBCT. Third, identifying marked anatomical structures in digital panorama. Last, participants were asked to choose type of view and to name marked anatomical structure in CBCT images. Results showed that majority of participants used panorama in routine work, most did not think panorama was suitable for implant planning. 58.3% students and 50% interns did not use CBCT before. Both levels obtained knowledge on CBCT in faculty lessons, followed by internet. Future applications of CBCT reported highest in maxillofacial surgery for sixth year, and all fields of dentistry in interns. Most were willing to receive extended education in CBCT. High Correct identification of landmarks in panorama, while average correct identification of cross sections and marked landmarks in CBCT. It is concluded that the moderate students' knowledge of CBCT suggest that more training should be gained through continuing education.

“…By this imaging method, the maxilla, the body of the mandible and the maxillary sinuses are easily viewed in a single screen, the images produced have sections of variable magnification as well as thickness. 9 In implant treatment planning, the panoramic radiographs have become an important radiological tool for implant site assessment, as they are more affordable and readily available. 1 Digital panoramic radiography offers several advantages to conventional techniques (Zonographs).…”

“…For optimal results, a diagnostic template is necessary. 9 In Dentascan, the images (cross-sectional) are perpendicular to the axial imaging plane, so the angulation or tilt of the patient's head during the procedure is of utmost important. In this method, the images that are produced have a limited range of diagnostic gray scale.…”

For any dental implant procedure that is being carried out, the success will depend on a thorough pre-operative investigation. The quality, quantity and the volume of available bone at the planned implant site has to be assessed properly when planning a dental implant placement. When we speak of the fore-mentioned aspects pre-surgical imaging and its co-relation to clinical findings help assess the relation to the amount of bone available from underlying vital parts namely the sinus cavities, nasal floor, nerves, teeth and vessels. Different radiographic modalities have been advocated for its assessment. Intra Oral Peri-apical radiograph (two-dimensional) is one such modality that has lost its importance after the introduction of more advanced techniques like Cone Beam Tomography (three-dimensional). This article will help us understand how two-dimensional and three-dimensional imaging modalities go hand in hand while treating dental patients. It will also explain why the conventional imaging technologies are still required in this era of modern methods of imaging.

Artificial Intelligence Techniques for Automatic Detection of Peri-implant Marginal Bone Remodeling in Intraoral Radiographs

et al. 2023

View full text Add to dashboard Cite

Peri-implantitis can cause marginal bone remodeling around implants. The aim is to develop an automatic image processing approach based on two artificial intelligence (AI) techniques in intraoral (periapical and bitewing) radiographs to assist dentists in determining bone loss. The first is a deep learning (DL) object-detector (YOLOv3) to roughly identify (no exact localization is required) two objects: prosthesis (crown) and implant (screw). The second is an image understanding-based (IU) process to fine-tune lines on screw edges and to identify significant points (intensity bone changes, intersections between screw and crown). Distances between these points are used to compute bone loss. A total of 2920 radiographs were used for training (50%) and testing (50%) the DL process. The mAP@0.5 metric is used for performance evaluation of DL considering periapical/bitewing and screws/crowns in upper and lower jaws, with scores ranging from 0.537 to 0.898 (sufficient because DL only needs an approximation). The IU performance is assessed with 50% of the testing radiographs through the t test statistical method, obtaining p values of 0.0106 (line fitting) and 0.0213 (significant point detection). The IU performance is satisfactory, as these values are in accordance with the statistical average/standard deviation in pixels for line fitting (2.75/1.01) and for significant point detection (2.63/1.28) according to the expert criteria of dentists, who establish the ground-truth lines and significant points. In conclusion, AI methods have good prospects for automatic bone loss detection in intraoral radiographs to assist dental specialists in diagnosing peri-implantitis.
