A Simple Way to Intrude Overerupted Upper Second Molars with Miniscrews

Abstract

Various methods of using skeletal anchorage for the intrusion of overerupted maxillary molars have been reported; however, it is difficult to intrude the overerupted upper second molars because of the low bone density in the region of the tuberosity. This article illustrates a new treatment method using partial fixed edgewise appliances and miniscrews to intrude the overerupted upper second molars. The miniscrews were applied to reinforce the anchorage of the upper first molar. The intrusive force was generated by the Ni-Ti wire. The clinical results showed a significant intrusion effect without root resorption or periodontal problems. This report demonstrates that the combination of partial conventional fixed appliances with miniscrews is a simple and effective treatment option to intrude overerupted upper second molars, especially in situations where miniscrews cannot be inserted directly next to the second molar.

Intrusion of overerupted molars with temporary anchorage devices before prosthetic reconstruction: A case report

“…This is particularly beneficial because many adult patients are unwilling to undergo comprehensive orthodontic treatment. Single overerupted teeth have been successfully treated with the help of various temporary anchorage devices alone or with the help of partial fixed appliances 7,18–20 . In some instances, corticotomy might facilitate intrusion 21 …”

“…16,17 The main advantages are the ability to achieve true intrusion without any unwanted tooth movement of the surrounding teeth, precise and consistent dosing of the intrusive force and the possibility of local, problem-focused treatment. 7,[18][19][20][21] The aim of this article was to demonstrate a simple method used on two severe cases of overeruption of maxillary and mandibular posterior segments. Important clinical aspects of molar intrusion with respect to the surrounding anatomical structures are also discussed.…”

“…The use of skeletal anchorage devices has many advantages and seems to provide predictable results 16,17 . The main advantages are the ability to achieve true intrusion without any unwanted tooth movement of the surrounding teeth, precise and consistent dosing of the intrusive force and the possibility of local, problem‐focused treatment 7,18–21 …”

Miniscrews: Contemporary Applications in Orthodontics

“…Clinical results showed a significant intrusion effect without root resorbtion and periodontal problems. So it is a simple and effective way to intrude second molars especially in situations where miniscrews can not be inserted directly next to the second molar (17). according to Yanagita in 2013 and after treatment a case of severe open bite due to traumatic condylar fracture non surgically, Although there was some relapse, results suggest that implant anchorage is useful for correcting anterior open bites originating from condylar fractures (18).…”
