Noninvasive palatal implant removal


Hänggi, Michael; Kuhn, Mirjam; Göllner, Peter; Schätzle, Marc (2015). Noninvasive palatal implant removal. Clinical Oral Implants Research, 26(12):1503-1505.

Abstract

OBJECTIVE
Orthodontic palatal implants are commonly used and do provide reliable absolute anchorage to assist orthodontic treatment. However, once treatment is completed, removal of these temporary implants is not considered easy or risk free. This short communication presents a clinical case in which a novel noninvasive procedure was applied to remove an osseointegrated palatal implant.

MATERIAL AND METHODS
A customized explantation tool, tightly fixed to the implant and precisely grasping the implant's head, was used in combination with a ratchet to unscrew the implant instead of the traditional removal by trephine.

RESULTS
Only a topical anesthetic was necessary before the implant-bone contact was broken by turning the ratchet counterclockwise. The implant was retrieved without any local anesthesia. The explanted palatal implant had no bone appending to it, except in its apical anti-rotational grooves, and the healing process thereafter was unproblematic.

CONCLUSIONS
Noninvasive palatal implant removal offers a simple and fast approach for explantation. Moreover, it might reduce the risk of adverse patient reactions, iatrogenic tooth and nerve injuries, and possible oro-antral communications.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
