Implant insertion torque value in immediate loading: A retrospective study. [PDF]

Med Oral Patol Oral Cir Bucal, 2019
The aim of this study is to verify if the Insertion Torque Value (ITV) of 32 Ncm for immediate loading protocol (ILP), as indicated by literature, is still, with the advance in implant research, a real significant cut-off for long-term implant survival ...

Primary stability, insertion torque, and bone density of conical implants with internal hexagon: Is there a relationship?

, 2013
Between implants and peri-implant bone, there should be a minimum gap, without micromotions over a threshold, which could cause resorption and fibrosis. The higher the implant insertion torque, the higher will be the initial stability.

Speed-torque relationship for self-tapping bone screw insertion

, 2021
Bone screws are used for fixing implants and stabilizing fractures. Correct torquing of these screws is important for positive patient outcomes. A previously proposed model-based system may increase the accuracy of bone screw insertion, but this depends ...

Biomechanics of sacroiliac joint fixation using lag screws: a cadaveric study

Journal of Orthopaedic Surgery and Research, 2023
Background Iliosacral screw placement is ubiquitous and now part of the surgeon’s pelvic trauma armamentarium. More recent evidence supports sacroiliac arthrodesis for treating sacroiliac joint (SIJ) dysfunction in select patients.

Relation between insertion torque and tactile, visual, and rescaled gray value measures of bone quality: a cross-sectional clinical study with short implants

International Journal of Implant Dentistry, 2019
Background This study assessed the relationship between insertion torque and bone quality evaluated during surgery and in preoperative computed tomographic (CT) images analyzed either visually or by rescaled mean gray values (MGVs). The study also tested
