Masticatory Function Impact on Nutritional Intake After Implant Treatment: Metanalyses
Objectives: The relationship between compromised masticatory function and nutritional risk is not fully understood. This systematic review investigated whether improvement in masticatory function, after implant-treatment with complete or partial dentures, has a direct impact on the nutritional intake.
Methods: This report followed the PRISMA Statement and 10 databases were searched to find eligible studies, published until May 2019. Risk of bias was assessed, and random effects meta-analyses were applied to analyze mean differences between complete denture (CD) and overdenture (IOD) (review register in PROSPERO - CRD42019135744).
Results: Thirteen articles were included comprising both complete and partial edentulous patients (718 prosthesis in 606 patients (mean age = 66.6 years)). Improvements in masticatory function (masticatory performance and efficiency, bite force, and masseter muscle thickness) were generally reported after the conversion of conventional CD into IOD (P < 0.05). Fixed-effect meta-analysis (I2 = 0%) revealed no differences in nutrient blood level between CD and IOD wearers except for serum folate (3.55 nmol/L in favor to IOD wearers (P = 0.001)). After 12 months of use, subjects using both prostheses (CD or IOD) increased blood levels of albumin and vitamin B12 (P<0.05). No differences were observed in body mass index (P>0.05). For partially edentulous, the conversion of conventional removable partial denture (RPD) into implant-retained partial denture (IRPD) improved masticatory function outcomes (P<0.05) while increased daily energy (P = 0.008), carbohydrate (P = 0.016), protein (P = 0.023), calcium (P = 0.008), fiber (P = 0.016), and iron (P = 0.016). Higher intake of fiber (P = 0.007), calcium (P = 0.002) and iron (P = 0.03) with significant reduction in cholesterol (P = 0.02) were observed when IRPD was replaced by fixed implant-supported denture.
Conclusions: Improvements in masticatory function after the use of implant-based prostheses promote benefits on nutrition, especially for partial edentulous patients.
