Major advances in minimally traumatic surgery in implantodontics: the concise systematic review

Introduction: Dental implant procedures have reached about one million dental implants per year in the world. In this context, it is necessary to establish the state of the art of minimally traumatic procedures for dental implants, especially after bone graft procedures and/or the use of biomaterials for bone elevation. In this context of optimizing techniques for better management of dental implants, faster and more accurate methods were developed by dentists, with post-operative results with better results and quality of life, through minimally invasive procedures. Objective: To carry out a concise systematic review of minimally traumatic surgery for dental implants, as well as to elucidate the main techniques for this. Methods: The rules of the Systematic Review Platform-PRISMA were followed. The survey was conducted from July 2021 to October 2021 and was developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. Study quality was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: Since the most primordial extraction techniques were created and developed, several attempts have been made to minimize the professional's effort, reduce surgical time and alleviate bleeding and inflammatory processes, edema, pain, and ecchymosis that can affect patients, in the trans and postoperative periods. Thus, the maximum preservation of the integrity of the soft tissues (papillae and free and inserted gingival band) adjacent to the prosthetic spaces should be sought; preservation of the alveolar bone ridge level. Based on the histological concept in which living tissues are formed by cells joined by thin elastic tissue and with nerve fibrils, capillaries, lymphatic and blood vessels. The disruption of these cells by surgical trauma provides the release of enzymes that delay healing. For this reason, surgical trauma should be minimized. Conclusion: There are many attempts to minimize the professional effort, reduce surgical time and alleviate bleeding and inflammatory processes, edema, pain, and ecchymosis that can affect patients. Thus, the maximum preservation of the integrity of the soft tissues adjacent to the prosthetic spaces and the preservation of the level of the ridge of the alveolar bone to achieve a minimization of surgical trauma must be sought.

Major approaches to minimally traumatic surgery in dentistry: a systematic review

Introduction: It is estimated that in minimally traumatic dental surgery, synthesis studies with meta-analysis and decision analysis represent almost 29% of all studies. Most of the selected studies were carried out in the USA, Netherlands, and UK. These three countries and 15 journals accounted for nearly 50% of all publications. The remaining works were published in another 61 journals and originated from 32 other countries, including Brazil. Objective: This study aimed to demonstrate, through literature review and case reports, the evolution and consequent importance of improving minimally traumatic surgery techniques in dentistry. It was hypothesized that there were statistically significant results about advances in the attempt to minimize trauma. Methods: The research was carried out from July 2021 to October 2021 and developed based on Google Scholar, Scopus, PubMed, Scielo, and Cochrane Library. The inclusion and exclusion criteria were systematic review studies, meta-analysis, controlled and randomized cases, non-randomized clinical cases, and opinion articles, which addressed the term minimally traumatic surgery in dentistry. The quality of the studies was based on the GRADE instrument. The risk of bias was analyzed according to the Cochrane instrument. Results: Since the most primordial extraction techniques were created and developed, several attempts have been made to minimize the professional's effort, reduce surgical time and alleviate bleeding and inflammatory processes, edema, pain, and ecchymosis that can affect the patients, in the trans and postoperative periods. Thus, the maximum preservation of the integrity of the soft tissues (papillae and free and inserted gingival band) adjacent to the prosthetic spaces should be sought; preservation of the alveolar bone ridge level.

Multiscale Coupling of One-dimensional Vascular Models and Elastic Tissues

We present a computational multiscale model for the efficient simulation of vascularized tissues, composed of an elastic three-dimensional matrix and a vascular network. The effect of blood vessel pressure on the elastic tissue is surrogated via hyper-singular forcing terms in the elasticity equations, which depend on the fluid pressure. In turn, the blood flow in vessels is treated as a one-dimensional network. Intravascular pressure and velocity are simulated using a high-order finite volume scheme, while the elasticity equations for the tissue are solved using a finite element method. This work addresses the feasibility and the potential of the proposed coupled multiscale model. In particular, we assess whether the multiscale model is able to reproduce the tissue response at the effective scale (of the order of millimeters) while modeling the vasculature at the microscale. We validate the multiscale method against a full scale (three-dimensional) model, where the fluid/tissue interface is fully discretized and treated as a Neumann boundary for the elasticity equation. Next, we present simulation results obtained with the proposed approach in a realistic scenario, demonstrating that the method can robustly and efficiently handle the one-way coupling between complex fluid microstructures and the elastic matrix.

CONGENITAL CUTIS LAXA: A RARE GENODERMATOSIS

Cutis Laxa (CL) / generalized elastolysis / dermatomegaly is a heterogeneous group of disorders which are related to elastic tissue abnormalities. Depending on extent of abnormal elastic tissue, it may be mild or severe. Severe form presents with loose, inelastic, wrinkled skin resembling ill tted suit. Infant has characteristic facial features like old man appearance, a hooked nose, a short columella, a long upper lip with long philtrum, and everted lower eyelids. CL is categorised as congenital or acquired and the inheritance can be autosomal dominant or recessive, or X linked. Occasionally a few metabolic disorders like Menkes disease, disorders of glycosylation are associated with Congenital CL. Acquired cutis laxa has developed after a febrile illness and various inammatory skin diseases. Here we present a case of a full-term SGA (small for gestational age) female child born with features of CL.

Pseudoxanthoma Elasticum: Report of Two Cases

Elastic pseudoxanthoma is a rare disease with autosomal recessive inheritance, also known as Grönblad-Strandberg syndrome, characterized by pathological mineralization of the elastic fibers in the connective tissue, affecting principally the dermis of skin, media, and intima of blood vessels and Bruch’s membrane of the eye. The genetic defect of the disorder is located on chromosome 16p13.1 and disease is caused by the lack of functional ABCC6 protein, which in turn causes extracellular accumulation and deposition of calcium and other minerals in the elastic tissue. In this article we present two cases of this rare disease. We emphasize, in the diagnostic criteria, the importance of its early diagnosis and the current therapeutic approaches.

Analysis On Deep Learning Approaches For Timely Detection Of Osteoarthritis

Osteoarthritis is mainly a familiar kind of arthritis when an elastic tissue named Cartilage that softens the tops of the bones, cracks down. The Person with osteoarthritis can encompass joint pain, inflexibility, or inflammation and there is no particular examination for osteoarthritis and physicians take the amalgamation of both medical cum clinical record and X-rays imaging analysis to make a diagnosis of the state. Osteoarthritis is generally only detected following ache and bone scratch and in advance, analysis could permit for ultimate involvement to avoid cartilage worsening and bone injury. Through machine-learning algorithms, the system can be trained to automatically distinguish among people who would develop osteoarthritis and persons who would not with the detection of exact biochemical variances in the midpoint of the knee’s cartilage. The outcome of the Machine learning Techniques will give the persons who are pre-symptomatic by the occasion of the baseline imaging and also the reduction in liquid concentration. In this study, we present the analysis of various deep learning techniques for timely detection of osteoarthritis disease. Several subsets of machine learning called deep learning techniques have been in use for the timely detection of osteoarthritis disease; and therefore analysis is needed highly to choose the best as far as accuracy and reliability are concerned.
