Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main outcome was the incorporation of the graft to the donor site. These outcome was assessed by computed tomography, in three different periods: pre-operative, immediately after graft placement, and 9 motnhs after healing. Clinical measurements of thickness and volume were also performed, as well as bone biopsies of grafted areas, to evaluate the microarchitectural pattern and histolgoical incorporation of graft. The bone volume was expressed in mm³; the micro architechture was assessed by bone volume ratio, trabecular number, thickness and separation, also connectivity and trabecular pattern. The histological incorporation was assessed by percentage of mineralized tissue and percentage of remnant biomaterial. ;Another primary outcome was the clinical complications after graft placement, this complications were assessed by qualitative classfication, in each post operative appointments. The researches evalauted: wound dehiscence, paresthesia, wound infection, swelling, haemathoma, and seroma formation thoughout visual evaluation and inquiring. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome was the realibility of implant placement in grafted areas. This reliability was assessed thorghout implant instalation torque. The implant torque was measured by a digital torquimeter attached to the counter angle head, and measuren in Newtons, .;Another secondary outcome was the implant stability quocient, the stability was assessed by frequncimenter Ostell, measured in a standard scale betwenn 0 and 100, being 100 the most stable condition. | — |
