Evaluación estructural del implante dental sometido a diferentes torques de inserción. Estudio "in vitro"

El material más frecuentemente utilizado en la implatología oral en la es el titanio comercialmente puro, ya que presenta una gran biocompatibilidad y constituye el material ideal para conseguir la osteointegración con éxito a largo plazo tras la carga funcional 2.HIPÓTESIS DE TRABAJO Las diferentes hipótesis nulas que se plantearon con respecto a la relación de las diferentes variables observadas en nuestro estudio fueron las siguientes: 1.Ho:Fuerzas superiores a 80Nw/cm2 no presentarían ni deformidades,ni alteraciones en la superficie de los implantes de conexión externa ni en los de conexión interna. 2.Ho:Fuerzas superiores a 90Nw/cm2 no presentarían deformidades, ni alteración en la superficie, ni fisuras en los implantes de conexión externa ni en los de conexión interna. 3.Ho:Fuerzas superiores a 100Nw/cm2 no presentarían deformidades en el transportador del implante, ni alteraciones en los hexágonos de los implantes de conexión externa ni en los de conexión interna...

Does immediate loading affect clinical and patient-centered outcomes of mandibular 2-unsplinted-implant overdenture? : a 2-year within-case analysis

Objective To provide 2-year clinical- and patient-oriented data with regard to mandibular overdenture assisted by 2 immediately loaded unsplinted implants. Material and methods In this pre-post design, Phase-I clinical trial, 18 edentate individuals (62.4 ± 7.7 years) received a new set of complete denture. Then, following standard procedures, 3 threaded implants (OsseoSpeed TX™, Dentsply Implants, Mölndal, Sweden) were placed in the mandible in each patient, and locator abutments (Zest Anchors LLC, Escondido, U.S.A.) were inserted on the right and left side implants. The midline implant served as a control for within-patient comparison. The immediate loading was conducted within 24 h of surgery. Data were collected at baseline (T0), 12 (T1) and 24 (T2) months after immediate loading. The clinical outcomes included implant survival rate, crestal bone level changes and implant stability. These criteria were assessed through clinical and radiographic examinations as well as resonance frequency analysis. Patient-centered outcomes included patient satisfaction and oral health-related quality of life measured using validated questionnaires. Brunner-Langer approach was used for statistical analysis. Results Implant survival rate for immediate loaded implants was 91.7% at 2-year follow-up. None of the unloaded implants failed. There was no statistically significant difference at baseline and follow-ups with regard to clinical outcomes between loaded and unloaded implants. Patient satisfaction and quality of life improved (p < 0.0001) from baseline to 2-year follow-up. Conclusion Immediate loading protocol did not negatively affect clinical outcomes, satisfaction and quality of life of patients wearing 2-unsplinted-implant mandibular overdenture for 2 years. This conclusion requires confirmation by randomized control trials. Clinical significance statement Mandibular overdenture assisted by two immediately-loaded unsplinted implants is successful treatment based on 2-year clinical and patient-based outcomes.
