Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Radiological monitoring of peri-implant stability for 5 years performed by marginal bone loss measurement.;Clinical monitoring of peri-implant health for 5 years performed by the followings indicators: visible plaque index, presence of calculus, degree of peri-implant inflammation and probing depth.;Evolution of the masticatory function via masticatory performance and swallowing threshold tests anually performed for 5 years. | — |
Secondary
| Measure | Time frame |
|---|---|
| Primary and secondary stability of implants measured by resonance frequency analysis through the implant stability quotient (ISQ) registered by the Osstell® device.;Posterior bone loss measured on panoramic radiographs using proportional measurements of the posterior mandibular areas and a posterior area index (PAI).;Residual ridge reabsorption of the posterior and anterior residual in the maxilla measured by panoramic radiography evaluated using the proportional area measurements.;Bite strength assessed by digital gnatodinamometer .;Estimation of implant success and survival rates.;Survey of the types and frequency of prosthetic complications through the analysis of the records made in the annual periodic follow-ups after mandibular overdentures loading. | — |
