The treatment of teeth with posttraumatic external replacement resorption using EMD in conjunction with intentional replantation has shown a recurrence rate of ankylosis in 53% (13).
Treatment of replacement resorption by intentional replantation, resection of the ankylosed sites, and Emdogain-results of a 6-year survey.
If orthograde retreatment and endodontic microsurgery of a tooth with apical periodontitis are not feasible, intentional replantation has been considered the last means of retaining a natural tooth that would otherwise be lost to extraction [17-20].
From a total of 417 patients who were referred to the Department of Conservative Dentistry for endodontic microsurgery between March 2009 and August 2015, 42 C-shaped root canals that had undergone intentional replantation surgery were included in this study.
However, conservative treatment options such as reconstruction of the fractured fragments with adhesive resin followed by intentional replantation have been recently suggested .
However, the patient was reluctant for extraction and an alternative treatment plan was established which included bonding the fragments with a fluid resin cement without extraction and intentional replantation. The use of adhesive resin with intentional replantation has been reported in the literature for complete and incomplete vertical root fractures.
The treatment alternatives are protective sealing of the invagination area, endodontic treatment, intentional replantation
, periapical surgery, and extraction (6,7).
The other case with a horizontally displaced permanent premolar did not have a chance to erupt spontaneously; thus intentional replantation was chosen as the treatment.
Intentional replantation could also be employed in teeth which have a great strategic value for maintaining the balanced occlusion.
The role of intentional replantation
has also been reported in very complex forms of type III dens invaginatus.99,73
A combination of endodontic, intentional replantation
and Emdogain therapy was used to sucessfully treat a maxillary lateral incisor that had a palatogingival groove by Al-Hezaimi K et al (7) in 2004.
