Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The bone gain in the horizontal (buccolingual) direction clinically. Timepoint: Before intervention and 6 months after intervention. Method of measurement: The width of bone in the buccolingual direction will be measured clinically by a dental caliper.;The bone gain in the horizontal (buccolingual) direction radiologically. Timepoint: Before intervention and 6 months after intervention. Method of measurement: The width of bone in the buccolingual direction will be measured radiologically by CBCT. | — |
Secondary
| Measure | Time frame |
|---|---|
| Histomorphometric analysis. Timepoint: 6 months after intervention. Method of measurement: A trephine will be used to get a bone core from the proposed implant site and for histological evaluation. After fixation and decalcification, the samples will be stained with hematoxylin and eosin (H&E), and bone formation, bone area percentage, and blood vessel formation will be evaluated.;Implants insertion torque. Timepoint: 6 months after intervention at the time of place implants. Method of measurement: Implants insertion torque will be measured by implant ratchet.;The implant stability quotient (ISQ). Timepoint: 6 months after intervention at the time of place implants. Method of measurement: The implant stability quotient (ISQ) will be measured by the Osstell device. | — |
