Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The success rates of implants, that will be evaluate by clinical analyzis, of the short implants installed in the posterior maxillary region will be similar or superior (around 5%) to the success rates of conventional implants installed in the same area, but where the grafting procedure was previously performed. | — |
Secondary
| Measure | Time frame |
|---|---|
| The bone level to be evaluated by radiographic analyzes of the short implants installed in the posterior maxilla will be similar or superior (less than 2 mm of bone loss) than in the conventional implants installed in the same area, but where the grafting procedure was previously performed.;The stability of the implants to be analyzed by frequency of resonance in short implants installed in the posterior region of the maxilla will be similar or inferior (about 10%) than in conventional implants installed in the same area, but where the grafting procedure was performed previously . | — |
