BACKGROUND The aim of the present study was to evaluate the relationship between insertion torque and stability of miniscrews in terms of resistance against dislocation, then comparing a self-tapping screw with a self-drilling one. METHODS Insertion torque was measured during placement of 30 self-drilling and 31 self-tapping stainless steel miniscrews (Leone SpA, Sesto Fiorentino, Italy) in s...

AIM To highlight one of the possible complications associated with the inter-radicular placement of orthodontic miniscrews. SUMMARY This case report describes the endodontic treatment and surgical repair of an iatrogenic root perforation involving a maxillary first molar tooth following the placement of an orthodontic miniscrew placed for anchorage purposes in the treatment of an adult patien...

Paradigms have started to shift in the orthodontic world since the introduction of mini-implants in the anchorage armamentarium. Various forms of skeletal anchorage, including miniscrews and miniplates, have been reported in the literature. Recently, great emphasis has been placed on the miniscrew type of temporary anchorage device (TAD). These devices are small, are implanted with a relatively...

Piezoelectric surgery is a novel surgical approach used in orthodontic treatment for rapid tooth movement. This paper presents a case series wherein osseous outgrowths were observed in response to piezosurgery-assisted en-masse retraction. Sixteen patients requiring upper premolar extractions were treated with miniscrew-supported en-masse retraction and received minimally invasive decortication...

Primary stability is absence of mobility in the bone bed after mini-implant placement and depends on bone quality among other factors. Bone quality is a subjective term frequently considered as bone density. The aim of this preliminary study was to evaluate bone density in two bovine pelvic regions and verify the primary stability of miniscrews inserted into them. Forty bone blocks were extract...

The introduction of digital workflows and their combination with miniscrew assisted appliances has opened new enthusiastic perspectives in modern orthodontics. However, all currently use for orthodontic tooth movement, the miniscrews are inserted first maxillary bone, often by means a surgical guide, then appliance is fabricated secured over different fixation mechanisms. By doing so, some adap...
