Por qué importa

Se analiza el comportamiento clínico de restauraciones sobre implantes fabricadas en zirconio monolítico o estratificado parcialmente en un seguimiento de hasta 5 años. La escasez de datos clínicos a largo plazo sobre estas prótesis justifica la relevancia de este estudio retrospectivo. Se evaluaron complicaciones técnicas y mecánicas en coronas, puentes y rehabilitaciones completas, identificando decementaciones y aflojamientos de tornillos como las más frecuentes, junto con algún chipping. A pesar de estas incidencias, el estudio concluye que el zirconio en estas modalidades presenta un buen comportamiento clínico en el periodo estudiado, ofreciendo información útil para la toma de decisiones en la práctica diaria al planificar y ejecutar rehabilitaciones implantosoportadas.

Abstract original

Objective . Long‐term clinical data on the success and complication rates of monolithic or minimally veneered zirconia implant‐supported restorations are lacking. Hence, the purpose of this retrospective clinical study was to analyze the complications of monolithic or partially veneered zirconia implant‐supported restorations up to 5 years follow‐up. Material and Methods . Single crowns, bridges, and full‐arch rehabilitations were included. The selection process was achieved by reviewing data from the prosthetic laboratory and excluding cases in which zirconium and full‐ceramic coating restorations were used. A total of 154 restorations were included (82 monolithic and 72 with buccal ceramic stratification). All the complications encountered, and the solutions applied, were explained. Results . A total of 93 restorative units had a follow‐up of between 24 and 60 months, and 61 restoration units had a follow‐up of between 12 and 24 months. A total of 7 complications were encountered (14.58% of cases; 95.45% per prosthetic unit). The technical complication rate was 2.08% (one case of minor chipping in one prosthetic unit); regarding the mechanical complications, four decementations (8.33% of the cases) and two screw loosening (4.17% of the cases) were encountered. Conclusions . Considering the limitations of this study, it can be concluded that monolithic or partially veneered zirconia implant‐supported restorations have a good clinical behavior during a follow‐up period of up to 5 years.
