Success Rate of the Miniscrews in the Mandibular Buccal Shelf

100 participantsStarted 2016-01

Plain-language summary

Stability of the orthodontic miniscrews placed in the mandible is still considered to bare higher risk of failure compared to other intraoral locations. The aim of our study was to determine the influence of the miniscrew size on their long-term stability, occurrence of oral mucosa inflammation and pain lasting over 48 hours after implantation.

Inclusion Criteria: * generally healthy Caucasians * mild Class III maloclussion that required an absolute anchorage for en-masse distalization in the mandible * hypodivergent or normal angle between the maxillary and mandibular planes * excellent oral hygiene Exclusion Criteria: * Hyperdivergent angle between the maxillary and mandibular planes * unfavorable anatomical conditions - e.g. presence of a strong frenulum potentially irritating the miniscrew head during chewing and/or facial movement

What they're measuring

Assessing the stability of miniscrews

Timeframe: The first evaluation was performed 2 weeks after miniscrew insertion and then every 4-6 weeks (at follow-up visits) throughout the duration of distalization (up to 2 years).

Assessing the presence of peri-implantitis

Timeframe: The first evaluation was performed 2 weeks after miniscrew insertion and then every 4-6 weeks (at follow-up visits) throughout the duration of distalization (up to 2 years).

Assessing the presence of pain lasting longer than 48 hours after implantation.

Timeframe: two weeks
