The roughness of lithium disilicate surfaces is a critical factor in dentistry due to its impact on adhesion and the quality of dental restorations. Injection and milling methods are two common approaches for manufacturing these structures, and through an in-depth review of the scientific literature, we aim to identify how each method affects the roughness of. The surfaces. Relevant studies comparing the effects of injection and milling on the surface quality of lithium disilicate structures were collected, evaluating advantages, disadvantages, and potential implications for dental practice. This study compared the surface roughness of lithium disilicate frameworks fabricated using the injection and milling methods. The injection method was found to produce smoother and more homogeneous surfaces, with statistically significant differences compared to milling. Although milling allows for greater precision and speed, the lower roughness of the injected material may improve cement adhesion and reduce plaque buildup, benefiting the longevity of the restorations. The choice of method will depend on the clinical need, the available equipment, and the aesthetic requirements of the patient.Item Revisión bibliográfica evaluativa sobre cambios dimensionales que experimentan los yesos dentales tipo III(Universidad Santiago de Cali, 2024) Rodríguez Vivas, Luis Miguel; Sánchez Arteaga, Claudia Patricia (Directora)This study examines dimensional changes in type III dental casts also known as high-strength casts, with factors such as humidity, temperature, setting time and material composition the main causes including dehydration and expansion during the setting process. this gypsum is a natural mineral that is identified as a type of sedimentary rock composed of calcium phosphate. To make gypsum, this material is subjected to the calcination process at a temperature of 120ºC and is mixed with water for proper setting, which will result in a dehydrated calcium sulfate rock. The evaluation of dimensional changes in type III dental casts is a crucial area in the dental laboratory since these materials play a fundamental role in the precision and durability of prosthetic work.Item Análisis sobre adaptabilidad en la población rehabilitada con coronas CAD CAM(Universidad Santiago de Cali, 2024) Zapata Cossio, Anlly Sorancy; Vásquez Bonilla, Jhoan Ariel; Obando Bravo, Oscar Armando (Asesor)The world has had great technological advances and the health area is no exception. We will obtain more detailed knowledge when creating a dental piece digitally. The high demand for dental laboratories in our town ¨Cali Valle del Cauca¨. It leads us to the question of how many use the digital method as the main option for their work. The Santiago de Cali University gives us the opportunity to have in the academic curriculum the development of digital skills in the area of design and manufacturing of dental pieces. However, beyond the technical effectiveness of CAD/CAM crowns, the crucial question arises about how these prostheses impact the adaptability of rehabilitated patients. Adaptability, understood as the ability of individuals to adjust and function effectively in various situations, becomes a fundamental factor in the dental rehabilitation process. This analysis aims to explore this aspect in depth, considering both the physical and psychosocial aspects involved in the adaptation of the population rehabilitated with CAD/CAM crowns. For this reason we want to delve deeper into the topic, since many people do not have this opportunity. When documenting this process, an analysis was made of certain laboratories and dental centers; about the shortcomings that they present regarding the topic. We intend to have clear information for those students who are just beginning this process, since their learning will be a little easier. And to the health personnel in the dental area who do not handle this issue very well; They will be able to obtain knowledge and a better economic income.Item Caracterización del tejido gingival en una población estudiantil de la Universidad privada Santiago de Cali en el periodo 2023(Universidad Santiago de Cali, 2024) Ramos Tintinago, Danna Yuley; Loaiza Maturana, Valeria; Hernández Sánchez, Leidy Natalia (Directora)Introduction: The gingiva is an area of the masticatory mucosa adapted to adhere to the tooth and protect the deep structures represented by the dental element. The gingiva has a pale pink color and a smooth appearance that can be shiny or opaque when its keratinization decreases. Oral rehabilitation is linked to the patients' requirements, and concepts and criteria for the study of gingival tissue characterization are developed. Objective: To characterize the gingival tissue in a population between 17 and 25 years of age attending the Maxillofacial Radiology Center of the University of Santiago de Cali, in the period 2023. Methods: Descriptive study, taking photographic images with standardized parameters of the maxillary and mandibular anterior zone to identify the characteristics of the gingival tissue. Results: Conclusions: The patient's aesthetics does not depend only on the teeth but also on a compensation with the gingival space and the gum, and in this case being able to photographically identify the differences in the gums, the aesthetics at the time of applying in the study of the characterization of the gingival tissue. Keeping in mind that the gum also plays a role in carrying out the rehabilitation, it is required to have a natural nature of it, since each person has different features in the gingival tissue according to their characteristics. It is important to highlight that the gingival tissue changes and has different features depending on each person. This requires great importance in terms of oral rehabilitation as in dentistry, whether a patient has healthy gums or, on the contrary, if he is a patient who requires oral rehabilitation to identify not only the shape and characteristics of your teeth but also your gums according to the soft tissues that surround them.Item Protocolo para la elaboración de una corona en zirconio cemento atornillada neoden 4.0(Universidad Santiago de Cali, 2023) Tamayo Ayala, Sharon Yuliana; Benavidez García, Leidy Tatiana; Lopez Quenguan, Camila; Rosales Basto, Alejandra María (Director)Item Niveles de contaminación por ruido de los motores de alta en el laboratorio de fundición de la Universidad Santiago de Cali, 2018(Universidad Santiago de Cali, 2019) Cabezas Guerrero, Giseth Yolima; Peña Possu, Nasly; Ruiz Correa, Jennifer; Rico Ceballos, Carlos Alberto (Director); Valencia Llanos, Carlos Humberto (Director)
