Mini-screw implants for orthodontic anchorage

shutterstock_147687233

14 studies, 7 of which were RCTs were included in this review of min-screw implants to prevent anchorage loss during orthodontic treatment. The findings suggest a small but clinically important reducing in anchorage with mini-screw use. However more high quality studies and information on adverse effects is needed.

Mini-screws for orthodontic treatment- self drilling or self-tapping?

Six studies were included in this review comparing the success rates of self-drilling and self-tapping mini-screws in orthodontic practice. The findings suggest no difference but the studies were small and of short duration and none of the included studies was a randomised trial so the findings should be interpreted cautiously.

This recent update of a Cochrane review considers the question as to whether surgical or conventional anchorage is more effective. Surgical anchorage was more effective but there is limited information on patient reported outcomes such as pain.

Yesterday (Dental Elf 13th Nov 2012) we looked at a systematic review assessing failure rates of mini-screw implants for orthodontic anchorage.  Today we are looking at a review consider whether recommended maximum insertion torque values of 5 to 10 Ncm were associated with higher success rates of orthodontic mini-implants than those inserted with torque values [read the full story…]

Review suggests a modest failure rate for orthodontic mini-screws used for anchorage reinforcement

Orthodontic mini-screw implants have become a popular method of providing anchorage reinforcement during orthodontic treatment.  The aim of this review was to assess the failure rates for mini-screw implants used for orthodontic anchorage purposes and to identify any significant risk factors possibly affecting these failure rates. A wide range of databases (19 in all) were [read the full story…]
