Abstract
Las técnicas actuales de los implantes dentales, se encuentran en continuo avance para conseguir una mejor interacción entre el hueso y la superficie del implante.
En la actualidad, las conexiones externas e internas encuentran partidarios y detractores sobre su comportamiento en la pérdida ósea. Según Vázquez Álvarez, existen mayor número de estudios que sugieren pérdidas superiores de hueso periimplantario en conexiones externas, frente a las internas.
Peñarrocha y cols., consideran que existe un mayor remodelado crestal y pérdida ósea en implantes de conexión externa frente a implantes de conexión interna. Dentro de esta corriente de opinión, se pueden encontrar otras publicaciones como las de de Medeiros y cols., y Gioato y cols.
Por el contrario, otros autores como Lin Mi y cols., refieren no encontrar resultados significativos en la pérdida ósea crestal entre ambas conexiones. En esta línea de opinión, coinciden publicaciones como las de Schwarz y cols., y Espósito y cols.
A pesar de existir estudios comparativos que evalúan diferentes conexiones protésicas y superficies de implantes, la literatura científica arroja escasez de trabajos científicos en los que se valore el comportamiento óseo con conexiones internas y externas, junto con diferentes cuerpos, superficies y localizaciones en los maxilares. De ahí que el propósito de este trabajo de investigación será analizar dichos aspectos...
OBJETIVOS: 1. Observar comportamiento tejidos blandos periimplantarios mediante sondaje. 2. Realizar control de placa, entre sistemas analizados. 3. Evaluar pérdida ósea individual entre sistemas. 4. Determinar relación pérdida ósea/cuerpo. 5. Observar relación pérdida ósea/localización. 6. Valorar diferencias pérdida ósea/diferentes conexiones. 7. Establecer porcentaje éxito y supervivencia cinco años seguimiento...
The current techniques of dental implants are in continuous advance to achieve a better interaction between the bone and the implant surface. Currently, external and internal connections find supporters and detractors about their behavior in bone loss. According to Vázquez Álvarez, there are a greater number of studies that suggest higher peri-implant bone losses in external connections, compared to internal ones. Peñarrocha et al., Consider that there is a greater crestal remodeling and bone loss in externally connected implants compared to internally connected implants. Within this current of opinion, other publications such as those of Medeiros et al., And Gioato et al. On the contrary, other authors such as Lin Mi et al., Report not finding significant results in crestal bone loss between both connections. In this line of opinion, publications such as those of Schwarz et al., And Esposito et al. Despite the existence of comparative studies evaluating different prosthetic connections and implant surfaces, the scientific literature shows a paucity of scientific studies that assess bone behavior with internal and external connections, along with different bodies, surfaces and locations in the jaws. Hence, the purpose of this research work will be to analyze these aspects. OBJECTIVES: 1. Observe peri-implant soft tissue behavior by probing. 2. Perform plate control between analyzed systems. 3. Evaluate individual bone loss between systems. 4. Determine bone loss / body ratio. 5. Observe bone loss / location relationship. 6. Assess differences in bone loss / different connections. 7. Establish percentage success and survival five years follow-up...
