    Avaliação comparativa entre as técnicas All-on-four e Four-on pillars em planejamentos virtuais 3D associadas a cirurgias guiadas em maxilas atróficas
    (Universidade Brasil, 2021) Maia, Marcelo do Lago Pimentel; Magalhães, Daniel Souza Ferreira
    Thorough technical knowledge and anatomical understanding are critical for optimal surgical results. The difficulty of complete maxillary surgery can vary significantly depending on the complexity of the anatomy or bone defect. Guided surgery is currently a relevant option for bringing to the patient fewer surgical complications and is directly related to 3D virtual planning for the success of the case. In this work, we analyze and compare two methods of planning guided in software for the manipulation of dental implants, associated with the All-on-four (A.F.) and Four-on-pillars (F.P.) techniques used in patients with atrophic maxillae. Forty-two images of totally edentulous patients were analyzed, 30 of which were planned using ImplantViewer software for volume assessment and ImageJ software for area assessment. The volumes were acquired in a CRANEX 3D volumetric tomograph model from the Soredex brand. In each planning, the height and width of the bone remnant was used as guidance and the implants were installed virtually. The average area of the Four on-pillars technique was 4.9x (p<0.0001) greater than the average area with the All on-four technique, this represents a difference of 489%, which in the same force applied by the jaw we have a 4.9x lower pressure, that is, a better distribution of forces on the jaws. It was not possible to notice a statistical difference between the success proportions (p=0.2542), showing that the techniques have a non-different (similar) success proportion. We conclude that the area formed in the Four-on-pillars surgical planning is larger than in the All-on-four planning and also that there is no technique with successful advantages over another, therefore the Four-on-pillars technique becomes an excellent option as a treatment for atrophic jaws.

    In clinical practice, professional activities are subject to various occupational risks, among which biological risks stand out for involving pathogens such as bacteria, fungi, protozoa, viruses, and parasites. These agents can invade the body via cutaneous, digestive, and/or respiratory routes, manifesting according to the individual’s immune response. To ensure safe practice and minimize potential contamination, biosafety measures include adopting rigorous protocols and using Personal Protective Equipment such as latex gloves. However, these products can present variations in quality and mechanical resistance among different brands, which compromises the safety of professionals and patients. Therefore, this study aimed to evaluate the quality of latex procedure gloves used in dental clinics, focusing on their mechanical resistance and impermeability. Four brands were analyzed through visual inspection and integrity testing, impermeability testing, and tensile strength tests, which made it possible to determine the maximum force, maximum tension, and elongation before rupture. Dimensional tests revealed no significant difference in glove length among the manufacturers, and width remained consistent, with no notable differences between brands A and D. In the impermeability test, deformation was observed in all brands, with gloves A and B showing no tears, while gloves C had multiple holes and gloves D exhibited leakage near the cuff. Regarding tensile strength, a good stretching capacity before rupture was found, with a maximum force ranging from 12.16 N to 17.94 N (mean of 14.86±2.45 N) and a maximum tension ranging from 38.30 MPa to 56.52 MPa (mean of 46.81±7.76 MPa). Elongation values ranged from 907.04% to 1137.21%, with a mean of 1037.32±89.20%, indicating differences in performance among the analyzed brands and underscoring the importance of carefully selecting products with proven quality control. It is concluded that significant differences exist in terms of impermeability and mechanical resistance of latex gloves, emphasizing the need for a thorough evaluation of these materials to ensure the safety of professionals and patients, thereby helping reduce biological risks in clinical practice and serving as a basis for future research on the quality of this personal protective equipment.

    Determinantes da adesão retenção e estabilidade em próteses totais convencionais
    (Universidade Brasil, 2024) Costa, César Cezario da; Arruda, Farid Jamil Silva de
    Conventional complete dentures are a widely adopted solution for the rehabilitation of edentulous patients, with the aim of restoring both oral functionality and aesthetics. However, the success of these prostheses is directly linked to their retention and stability, which are essential for the comfort and effectiveness of the treatment. Objectives: The present study aims to analyze and summarize the factors that influence adhesion, retention, and stability in conventional complete dentures, providing evidence-based guidelines that can assist dental professionals in improving clinical practices and, consequently, the quality of life of patients. Material and Methods: An integrative literature review was carried out, focusing on articles published in the last 20 years in databases such as PubMed and Scielo. The search included specific terms related to retention and stability in complete dentures, prioritizing systematic reviews, controlled clinical trials, and cohort studies. The studies were selected and analyzed based on their methodological quality, relevance of the results, and contribution to current knowledge on the subject. Results and Discussion: The analysis of the studies revealed that the retention and stability of complete dentures are influenced by a series of interrelated factors. Among the anatomical factors, the morphological characteristics of the oral cavity, such as the height and shape of the alveolar ridge, stand out, which directly influence the adhesion of the denture. Physiological factors, such as the quality and quantity of saliva and muscle tone, also play a crucial role in retention. Regarding materials, the choice of prosthesis components, including acrylic resin and other materials used, can significantly affect its performance. Conclusion: This study concludes that the retention and stability of conventional complete dentures are the result of a complex interaction between anatomical, physiological and material factors. A personalized approach, which considers the specificities of each patient, is essential to optimize rehabilitation results. The practical application of the evidence discussed can lead to significant improvements in treatments, increasing patient satisfaction and the effectiveness of the dentures.

    (Universidade Brasil, 2016) Antonio, Gláucia Lopes; Haleplian, Paulo; Rocha, Bruno Soares
    The fixed oral rehabilitation of edentulous ridges has been supported by the literature and successfully used in everyday practice. However, professionals are challenged daily to seek new treatment options, because there are still some limitations in rehabilitation treatment. In some cases of edentulous patients, treatment with implant-supported prosthesis it is almost impossible without complex techniques such as nerve transposition and grafting in the posterior maxilla and mandible. A technique described in the literature that has been used very successfully is called the All-on-four. It consists of the insertion of four implants, and the inclined distal and loading with immediate loading. Allowing the placement of longer implants, Improving support prosthetic arm less "cantilevered" distance inter implant and anchoring in the bone. The aim of this study is to make a literature review on the All-on-four system rehabilitation with immediate loading in edentulous jaws, evaluating whether this is a safe and feasible technique.
