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.

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 24612346Chrcanovic/2014Immediately-loaded single implants: Studies - 2 patients- 73 implants- 146.Systematic review of randomized trials
Key resultsOut of two included studies, it can be suggested that a low insertion torque of immediately-loaded single implants increases the implant failure rate.
#2) 23543525Esposito/2013Immediately-loaded single implants: Studies - 2 patients- 73 implants - 146 Systematic review of randomized trials
Key resultsOut of two included studies, it is suggested that a high degree of insertion torque is a key prerequisite for successful immediate or early loading single implant procedures.
#3) 23304687Cannizzaro/2012Immediately-loaded single implants in 50 patients.Randomized Controlled Trial
Key resultsAt a 6 month follow-up, 7 implants inserted with “medium torque” (25-35Ncm) failed, whereas 0 implants inserted with “high torque” (>80Ncm) failed.

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.
