“…Mild apical root resorption after molar intrusion has been reported previously 15,16 ; however, root resorption in the mesial aspect after significant molar protraction has not been a finding in clinical reports. 5,17 Interestingly, although the orthodontic movements were applied similarly between the right and left sides, the left side did not present these changes. Moreover, at the 5-month and 1-year followup appointments, resorption on the mesial aspect of the mandibular molar showed signs of repair in the periapical radiograph.…”

This case report describes the interdisciplinary management of a 58-year-old woman who was missing lower first molars and supraerupted maxillary first molars. The treatment plan included intrusion of the upper first molars and corticotomy-assisted mandibular second molar protraction with the aid of temporary anchorage devices. Miniscrews were effective in intrusion of the maxillary first molars and protraction of the lower second molars. Although good functional outcome was achieved in 41 months, the corticotomy-assisted procedure did not significantly reduce the treatment time.

“…These positive treatment outcomes can be obtained even without the patient's cooperation. [8][9][10][11] Upadhyay et al [12][13][14] and Nagaraj et al 15 reported positive treatment outcomes using screws for retraction and depression of anterior teeth, and protraction of molars.…”

“…Mesial movement of molars is taxing on anchorage, especially in the mandibular arch [3–5]. Considering that the mandibular midline was already shifted to the agenesis side, skeletal anchorage was deemed an efficient option.…”

“…Considering that the mandibular midline was already shifted to the agenesis side, skeletal anchorage was deemed an efficient option. However, instead of placing a mini-implant [3, 5, 6], we decided to use the primary molar as a biological alternative. We induced ankylosis and used the mesial root as skeletal anchorage.…”

Induced ankylosis of a primary molar for skeletal anchorage in the mandible as alternative to mini-implants

BackgroundMesial protraction of mandibular posterior teeth requires increased anchorage to avoid undesired tooth movements. Orthodontic mini-implants have become a popular and successful way to increase skeletal anchorage in such cases. However, mini-implants may cause injury to adjacent teeth or anatomical structures and may lead to tissue inflammation. Induced ankylosed primary teeth have been used in the past as abutments for the protraction of the maxilla in cases of maxillary retrognathism. However, this technique has not been described in the literature for the protraction of mandibular molars. The aim of this paper is to present, through a case report, an alternative to mini-implant devices to maximize anchorage in the mandible by inducing ankylosis on a primary molar.FindingsA 13-year-old female with class II right malocclusion, deep bite, and congenitally missing right second premolars was referred for orthodontic treatment. Treatment plan involved removal of the primary teeth and mesial protraction of the posterior. In the mandible, ankylosis was induced on the retained primary second molar by extraction, bisection, replantation of the mesial part after endodontic treatment, and bonding of a rigid splint. Ankylosis was diagnosed after 10 weeks and a closing T-loop sectional wire was inserted to move the permanent first molar mesially. At 6 months, the remaining space was closed using elastic chain on a rectangular stainless steel wire with tip-back bends, supported by class II elastics.ConclusionsInduced ankylosis of primary teeth can be an alternative to orthodontic mini-implants in selected cases, with minimal risks and maximum biocompatibility.
