Al realizar un tratamiento en el sector anterior se debe tener una visión amplia, es importante realizar un trabajo multidisciplinario para poder asegurar un resultado óptimo. La pérdida de piezas dentarias en el sector anterior puede traer como consecuencia alteraciones en el reborde edéntulo como la pérdida de las papilas interdentales. Uno de los retos más difíciles al realizar un tratamiento rehabilitador es la preservación de las mismas. Existen diferentes técnicas para poder conseguirlas pero ninguna asegura el éxito a largo plazo. La confección de pónticos ováticos permite preservar las papilas interdentales dando como resultados tratamientos estéticos. A continuación se presenta un caso clínico en el cual se realiza una prótesis fija sobre dos implantes colocados en el sector anterior en el cual se conforman las papilas interdentales con el uso de pónticos ovát...

This descriptive and cross-sectional study addressed students' perceptions of a preliminary practice in dental preparation for a metal-free crown, conducted on the same clinical case using haptic simulation before patient treatment. The sample consisted of 6 final-year dentistry students who, using haptic simulation with scanned images of the same patient's mouth, prepared metal-free crowns prior to treating the patient. Data collection was carried out through two surveys. It was found that 66.7% (n=4) of the students considered this experience very useful, and 83.3% (n=5) mentioned that the experience provided them with confidence to perform the procedure on the patient. The results suggest that recurrent practice in haptic simulation of a clinical case, prior to patient treatment, is favorable for performance and provides greater confidence in carrying it out.

Objetivo: Evaluar in vitro la resistencia de unión de una cerámica feldespática según tipo, método y tiempo de aplicación del ácido fosfórico luego de acondicionarla con ácido fluorhídrico. Materiales y Métodos: Se elaboraron discos de cerámica feldespática IPS Classic (Ivoclar - Vivadent ®; Schaan, Liechtenstein) de 10 mm de diámetro por 2 mm de altura, los cuales fueron acondicionados con ácido fluorhídrico al 9% por 90 segundos. Las muestras fueron tratadas con dos tipos de ácido fosfórico al 37% Ultra Etch (Ultradent®, Utah, USA) y Prime Dental ® (Chicago, Il, USA) colocados con dos métodos de aplicación (activo y no activo), en tres diferentes tiempos de exposición sobre la superficie de la cerámica feldespática (30, 60 y 90 segundos). Se confeccionaron cilindros de resina Filtek Flow Z350 (3M TM ESPE TM; St. Paul, NM, USA) siguiendo los procedimientos adhe...

El objetivo: del presente estudio fue evaluar el efecto del tipo de superficie de la preparación dentaria en relación a la resistencia a la tracción de coronas metálicas completas cementadas con ionómero de vidrio sobre preparaciones dentarias con superficies pulidas y no pulidas. Material y métodos: Se realizaron 20 coronas metálicas en 20 piezas dentarias preparadas, las cuales se dividieron en dos grupos de 10 cada una, éstas fueron sometidas a la prueba de tracción con la máquina de tracción Hounsfield, para determinar la fuerza de tracción necesaria para dislocarla. Resultados: mostraron que las preparaciones dentarias con superficies no pulidas (607.03N) mejoran la resistencia a la tracción en comparación de las pulidas (359.90 N.)

Objective: To determine the perception of postgraduate students of a private university in Lima on the efficacy of the intraoral scanners (IOS) Primescan Dentsply Sirona® and Virtuo Vivo Straumann®. Materials and methods: Cross-sectional study in which 10 students of Oral Rehabilitation participated, who, after being trained, scanned a model using both IOS; subsequently, their perceptions were collected through a questionnaire. Results: The Primescan Denstply Sirona® IOS was considered by 80% (n = 8) and 100% (n = 10) of the students as having the best characteristics in scanning speed and flow, respectively; and the Straumann® Virtuo Vivo IOS was considered the most ergonomic by 100% (n = 10). Conclusions: The IOS Primescan Denstply Sirona® IOS was perceived as the fastest, sharpest and with the best scanning flow; and the Straumann® Virtuo Vivo IOS was considered the most ergonom...

Objective: To evaluate the micro-shearing bond strength in feldspathic ceramics through various methods of hydrofluoric acid residue removal and different application times. Materials and methods: An in vitro study in which 9% hydrofluoric acid was applied for 1 minute as a surface treatment on feldspathic ceramic discs. The samples were divided into 4 groups with 3 different application times and subjected to different removal methods: water and air spray; ultrasonic bath with distilled water; active application of 37% phosphoric acid for 1, 2, and 4 minutes; and a combination of 37% phosphoric acid actively applied for 1, 2, and 4 minutes followed by an ultrasonic bath with distilled water for 4 minutes. Cylinders of flowable resin were prepared and placed on the ceramic discs. Samples were subjected to micro-shear tests on a semi-universal testing machine. Results: The two-way ANOVA t...

This paper describes the student and teacher's perceptions of the process of introducing CAD-CAM technology in dental education. A cross-sectional and descriptive study was carried out; two questionnaires validated by expert judgment were used for data collection, and descriptive statistics were applied. It was obtained that 57.9 % of the students and 37.5 % of the teachers considered that the teaching of CAD-CAM technology should begin in the third year of studies; the training was helpful for both students and teachers, and this technology would be a procedure of choice for treatment with fixed prosthesis if they had it available. It is concluded that students and teachers positively perceive the introduction of CAD-CAM technology in the clinical courses of the dental career, and it would be a resource of choice for fixed prosthesis treatment.
