Por qué importa

Esta revisión sistemática analiza la evidencia disponible sobre los resultados clínicos y la calidad de vida de pacientes con defectos maxilares que utilizan prótesis obturadoras maxilares implantosoportadas. Se evaluaron tasas de supervivencia de implantes convencionales y cigomáticos, así como complicaciones protésicas, destacando la aflojamiento de tornillos como la más frecuente. Se concluye que los resultados clínicos son aceptables, considerando la supervivencia y las complicaciones, y que la calidad de vida de los pacientes se ve favorablemente afectada, a pesar de la heterogeneidad en el diseño de los estudios incluidos. Esta información es relevante para la planificación y el manejo de casos complejos en la práctica de rehabilitación oral.

Abstract original

PURPOSE: To systematically review the current evidence on clinical and patient-reported outcomes of implant-supported palatal obturator prostheses. MATERIALS AND METHODS: An electronic search of the PubMed, Web of Science, and Cochrane databases was carried out in June 2019. The titles and abstracts of all articles were screened by two independent reviewers. The references of the subsequently selected studies were further screened for potential articles. Assessment of the selected full texts was performed independently according to established inclusion and exclusion criteria. The quality of the selected studies was determined using the Newcastle-Ottawa scale. Interrater agreement on study selection was calculated using Cohen kappa statistic. RESULTS: The search yielded a total of 2,797 records. Ten studies were selected for data extraction, with a Cohen kappa value of 0.856. Five studies were prospective, and five were retrospective. The survival rates for conventional implants ranged from 21.42% to 100%, whereas for zygomatic implants, the survival rates varied from 30% to 100%. Four studies reported prosthodontic complications, with screw loosening being the most common. Patient quality of life (QoL) was analyzed in six studies. CONCLUSION: In spite of the limitations of the present review, it can be concluded that the clinical outcomes are acceptable in terms of survival rates, implant and prosthodontic complications, and QoL associated with implant-supported maxillary obturator prostheses. QoL of implant-supported prostheses in these patients are acceptable. The general study design was not homogenous between studies.
