The DTR Technique-Drilling through the Roots of Posterior Teeth for Anatomically Guided Immediate Implant Placement: A Cohort Study.

Aim: The present study clinically analyzes implant survival of immediate implant placement cases using the drilling through roots (DTR) technique for anatomically-guided implant site preparation, as an aid to placing immediate dental implants in multi-radicular teeth.

Materials And Methods: This clinical analysis utilized patients' electronic dental records who underwent immediate implant surgery using the DTR technique. All immediately placed implants were followed up regularly every year, after restoration.
