Intrusion method for a single overerupted maxillary molar using only palatal mini-implants and partial fixed appliances

●Bodily intrusion of a single overerupted maxillary molar is possible with only palatal mini-implants.●Combined use of direct and indirect anchorage increases the available insertion sites.●Bone levels around the extruded molar should be evaluated carefully before intrusion to avoid introducing vertical osseous defects.

Mandibular first molars are among the most frequently missing teeth in the adult dentition. As a result, the maxillary first molars are frequently overerupted. Conventional approaches to correct this undesirable molar position with skeletal anchorage usually include both buccal and palatal orthodontic mini-implants. Because palatal mini-implants have greater success rates than buccal ones, this article explains an intrusion method with only palatal mini-implants and limited fixed appliances to produce reliable intrusion of the overerupted molar while preventing undesirable side effects on the adjacent teeth.
