The Impact of Thread Length on Implant Stability

NCT05141851 | Completed

• 1 other identifier: The impact of thread length on
• Study Type: interventional
• Target: 23
• Locations: 1 country
• Sites: 1

Brief Summary

Some studies show that different types of threads in tapered implants result in differences in primary stability. The aim of this study is to a perform a prospective, controlled, randomized clinical trial comparing primary and secondary stability between long and standard thread implants in the treatment of partial edentulous patients.

Conditions

Implant Stability

Keywords

implant stability; implant threads

Outcome Measures

Primary Outcomes (1)

• primary dental implant stability

  measuring the ISQ value (implant stability quotient)

  On the 1 day of implants placement

Study Arms (2)

Implants with 0,7mm threads

ACTIVE COMPARATOR

Placement of Implants with 0,7mm threads

Device: Implants with 0,7 mm threads

Implants with 0,3mm threads

ACTIVE COMPARATOR

Placement of Implants with 0,3mm threads

Device: Implants with 0.3 mm threads

Interventions

Implants with 0,7 mm threads DEVICE

Implants were placed, with threads of 0.7 mm in the location of premolars and molars.

Implants with 0,7mm threads

Implants with 0.3 mm threads DEVICE

Implants were placed, with threads of 0.3 mm in the location of premolars and molars.

Implants with 0,3mm threads
