Theoretical and technical approaches to the clinical case: Advantages and disadvantages of present‐day pluralism

Subject. With the advent of advanced imaging technology and CAD/CAM technologies, the possibility of guided surgery has become of wide interest among implantology. The article is devoted to the use of surgical template implantation in the rehabilitation of a dental patient. It provides information about some advantages and disadvantages of the digital protocol in comparison with traditional dental implantation. The main stages of navigation surgery in a clinical case are described. Goal. To evaluate the actual clinical advantages and disadvantages of dental implant placement using a surgical template compared to the traditional treatment protocol. Methodology. The literature search was conducted in scientific search bibliographic databases such as PubMed, eLIBRARY, Medline, and Google Academy. More than 384 studies up to 2014 were found under the thematic headings "Dental implantation" and "Surgical template". During the study of these works, the sample included 56 articles and literature reviews. Conclusions. Recently, implant placement using a surgical template has become a popular treatment method among dental surgeons. The study of modern literature allowed us to formulate the main advantages and disadvantages of this method. Advantages of the method: precise positioning of implants; flap-free surgery reduces the operation time and is characterized by a favorable postoperative course; integration of restoration determinants in surgical planning, which leads to a more aesthetic, functional and predictable result of prosthetics; the possibility of pre-manufacturing a prosthesis based on the planned position of the implant; simplification of the surgical procedure for the dentist. However, this method is not without its drawbacks: the surgeon's inability to visualize anatomical structures; the risk of axis and depth deviation during implant placement; requires additional digital planning.

Microwave Breast Imaging

Microwave breast imaging has seen increasing use in clinical investigations in the past decade with over eight systems having being trialled with patients. The majority of systems use radar-based algorithms to reconstruct the image shown to the clinician which requires an estimate of the dielectric properties of the breast to synthetically focus signals to reconstruct the image. Both simulated and experimental studies have shown that, even in simplified scenarios, misestimation of the dielectric properties can impair both the image quality and tumour detection. Many methods have been proposed to address the issue of the estimation of dielectric properties, but few have been tested with patient images. In this work, a leading approach for dielectric properties estimation based on the computation of many candidate images for microwave breast imaging is analysed with patient images for the first time. Using five clinical case studies of both healthy breasts and breasts with abnormalities, the advantages and disadvantages of computational patient-specific microwave breast image reconstruction are highlighted.

Extreme variability has been observed in individual responses to stressors. It appears that a more detailed analysis of individual variation in cognitions related to stress may result in a greater understanding of their differential responses. An idiographic cognitive model of the psychological processes that mediate stress and that underlie stress management techniques is presented in the form of an illustrative series of hypotheses based on Beck’s cognitive model (Beck, Rush, Shaw, & Emery, 1979). The model is presented in detail and is applied to a clinical case example in which traditional nomothetic stress management techniques were ineffective. The advantages and disadvantages of a more idiographic approach to stress are examined as are the implications of the cognitive view of stress for research and practice.

Abstract The immediate postextractional implant insertion is a specific way of surgical approach to implanto-prosthetic treatment. This article addresses the indications, advantages, and surgical techniques of immediate postextraction insertion, illustrated with a clinical case. Objectives: presentation of the indications, advantages and surgical procedure of immediate postextractional implant insertion. Materials and methods: The present study considered the presentation of a case in which we opted for the insertion of implants immediately postextractionally as a therapeutic attitude. Results and discussions: The advantages and disadvantages of this therapeutic technique were represented as follows. The advantage of this technique is given by the shortening of the time necessary to complete the treatment until the prosthetic phase, the disadvantage being represented by the insertion of the implant in positions sometimes less advantageous to the prosthesis. Also, the fact that we could not preserve the alveolar ridge, keeping the bone volume necessary to insert the implant in the best position of the prosthesis by complying with the biomechanical principles, made over time, a series of complications that occurred due to vicious insertion of the implant and non-compliance with those biomechanical principles. Conclusions: The analysis of the case as a whole, represents the main premise from which any dental treatment must be started, so that the functionality of the prosthetic and aesthetic reconstruction will have to be taken into account when we choose the best treatment option.

Advantages And Disadvantages

Arterio-ureteral fistulas are a pathological condition characterised by the appearance of a defect between the blood vessels and adjacent distal segments of the ureter. Arterio-ureteral fistulas are relatively rare and potentially life-threatening, since they are associated with a high risk of developing haemorrhagic shock against the background of recurrent massive haematuria. This study describes the successful endovascular treatment of arterio-ureteral fistulas in a 51-year-old female patient. Evisceration of the pelvic organs was performed, followed by uretero-cutaneostomy and colostomy. Ureteral stents were installed to improve the outflow of urine and prevent ureteral stenosis. After stent removal, episodes of recurrent profuse bleeding from uretero-cutaneostomy occurred. On admission, multi-spiral computed tomography with angiography of the iliac arteries was performed. Extravasation of the contrast agent was not detected; however, external compression of the left common iliac artery by the left ureter was identified. After further examination, a balloon-expandable stent-graft was implanted into the left common iliac artery. The postoperative period thereafter was uneventful. This clinical case demonstrates the highly efficient endovascular treatment of the presented pathology and exemplifies the need for an integrated and multidisciplinary approach in the diagnosis and treatment of arterio-ureteral fistulas. Minimally invasive techniques can reduce surgical trauma and quickly isolate pathological blood discharge from the artery into the ureter. The advantages and disadvantages of endovascular technologies in the treatment of the presented pathology are also discussed.Received 16 February 2021. Revised 11 March 2021.

Masticatory Organ

The aim: To analyze modern research methods that allow to determine the features of the position of the tongue during the functions of swallowing and speech. Materials and methods: An analysis of 37 literature sources, which contains information about the methods of examination of patients with dento-maxillar anomalies. Conclusions: The functions of the tongue (swallowing and speaking) are very complex and coordinated movements that require the activation of many anatomical structures. Therefore, the disorders of the tongue during swallowing and speech are still considered by scientists as the most difficult in terms of correction and achieving of the long-term and stable results of orthodontic treatment. The study of modern trends in the diagnosis of the state of language functions in terms of understanding the functioning of the dental-maxillary area as a masticatory organ, the work and condition of the components of which depend on many systems of the human body, is relevant. Thus, the emergence of new and modifications of existing research methods undoubtedly expand the capabilities of modern orthodontists. However, this does not reduce the importance of the clinical stage of examination of patients with disorders of the maxillofacial area, including the functions of the tongue. Therefore, it is necessary to know and understand the advantages and disadvantages of modern and existing research technologies, which will allow to choose a communicatively integrated and differentiated approach to diagnostic issues in each clinical case.

Chemical Perturbation

The atomic force microscope (AFM) is capable of imaging electrically conductive and non-conductive surfaces at atomic resolution. When used to image biological samples, however, lateral resolution is often limited to nanometer levels, due primarily to AFM tip/sample interactions. Several approaches to immobilize and stabilize soft or flexible molecules for AFM have been examined, notably, tethering coating, and freezing. Although each approach has its advantages and disadvantages, rapid freezing techniques have the special advantage of avoiding chemical perturbation, and minimizing physical disruption of the sample. Scanning with an AFM at cryogenic temperatures has the potential to image frozen biomolecules at high resolution. We have constructed a force microscope capable of operating immersed in liquid n-pentane and have tested its performance at room temperature with carbon and metal-coated samples, and at 143° K with uncoated ferritin and purple membrane (PM).

The goal is to examine with high resolution cryo-SEM aqueous particulate suspensions used in coatings for printable paper. A metal-coating chamber for cryo-preparation of such suspensions was described previously. Here, a new conduction-cooling system for the stage and cold-trap in an SEM specimen chamber is described. Its advantages and disadvantages are compared to a convection-cooling system made by Hexland (model CT1000A) and its mechanical stability is demonstrated by examining a sample of styrene-butadiene latex.In recent high resolution cryo-SEM, some stages are cooled by conduction, others by convection. In the latter, heat is convected from the specimen stage by cold nitrogen gas from a liquid-nitrogen cooled evaporative heat exchanger. The advantage is the fast cooling: the Hexland CT1000A cools the stage from ambient temperature to 88 K in about 20 min. However it consumes huge amounts of liquid-nitrogen and nitrogen gas: about 1 ℓ/h of liquid-nitrogen and 400 gm/h of nitrogen gas. Its liquid-nitrogen vessel must be re-filled at least every 40 min.
