| Title |
Higher Insertion Torque Values Result in Better Success for Immediately-Loaded Single Dental Implants |
| Clinical Question |
For immediately-loaded single dental implants, does high insertion torque (>50Ncm) lead to better success rates compared to conventional insertion torque values? |
| Clinical Bottom Line |
For immediately-loaded single implants, high insertion torque is recommended for more predictable success. |

Comments on
The Evidence |
Both systematic reviews only had the same 2 Randomized Controlled Trials upon which to reach a conclusion. Therefore, the validity would be equal to having a single systematic review. With a low number of RCT’s available that answer the direct question and a lack of long-term follow-up, more investigations need to be done to ascertain a more confident conclusion. |
| Applicability |
The results of this investigation can be applied to any patient receiving a single implant. As the only difference in intervention is a higher insertion torque, the only limiting factor for single implants would be the inability to achieve primary stability. |
