Resumen

Las prótesis dentales fijas de resina compuesta impresas en 3D muestran buenos resultados clínicos a corto plazo en aplicaciones posteriores. El bruxismo aumenta el desgaste de la restauración, pero no afecta significativamente la supervivencia general de la prótesis.

Área de la Ciencia:

Odontología Odontología.
Ciencia de los Biomateriales Ciencia de los Biomateriales.
La prostodoncia es el área de la prostodoncia.

Sus antecedentes:

Los avances en odontología digital permiten la fabricación de restauraciones complejas.
La impresión 3D ofrece una técnica prometedora para la producción de prótesis dentales fijas de resina compuesta (FDP).
La evaluación del rendimiento clínico de estos FDP en regiones posteriores es crucial.

Objetivo del estudio:

Para evaluar la efectividad clínica de los FDPs de tres unidades de resina compuesta impresos en 3D en áreas posteriores.
Para comparar los resultados entre pacientes con y sin bruxismo durante un período de 28 meses.

Principales métodos:

Un estudio prospectivo incluyó a 40 pacientes (20 bruxistas, 20 no bruxistas) que requerían FDPs posteriores.
Los FDP fueron diseñados utilizando software CAD y fabricados con impresión 3D DLP utilizando resina compuesta biocompatible.
El rendimiento clínico se evaluó utilizando criterios modificados del USPHS durante un seguimiento promedio de 28 meses.

Principales resultados:

La mayoría de los FDP impresos en 3D demostraron un excelente rendimiento clínico (calificación Alpha) en ambos grupos.
El desgaste de restauración fue significativamente mayor en el grupo de bruxismo (40%) en comparación con el grupo sin bruxismo (10%).
Se produjo una fractura en el grupo de bruxismo; no se informaron complicaciones biológicas.

Conclusiones:

Los FDP compuestos de resina impresos en 3D exhiben un rendimiento clínico favorable a corto plazo para las restauraciones posteriores.
El bruxismo es un factor de riesgo significativo para el aumento del desgaste de estas prótesis.
Se necesitan más estudios a largo plazo para confirmar la durabilidad.

Palabras clave:

Design Example: Strain Gauge Bridge or Wheatstone Bridge

Design Example: Strain Gauge Bridge or Wheatstone Bridge

The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...

Wheatstone Bridge

Wheatstone Bridge

An ohmmeter is a resistance-measuring device. It works by applying a voltage to a resistor of unknown resistance and measuring the current across the resistor. The resistance value is deduced using Ohm's law. Usually, the standard configuration of an ohmmeter comprises a voltmeter or an ammeter. However, such configurations are limited in accuracy because the meters alter the voltage applied to the resistor and the current that flows through it.
Thus, for accurate resistance measurements, a...

Bridge rectifier

Bridge rectifier

The bridge rectifier is essential in electronics for efficiently converting alternating current (AC) to direct current (DC). Comprised of four diodes configured in a bridge layout, this rectifier effectively processes both the positive and negative halves of the AC waveform, making it superior to half-wave and full-wave center-tapped rectifiers in terms of voltage regulation and output stability.
Operationally, the bridge rectifier allows current flow through two of its diodes during each...

Cross-bridge Cycle

Cross-bridge Cycle

As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Predicting Reaction Outcomes

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
