114 SURGICAL UNCOVERING AND STIMULATION OFPHYSIOLOGICAL ERUPTION OF PALATALLYIMPACTED MAXILLARY CANINES: CASE REPORTSMiroslava Yordanova, Svetlana Yordanova , B. Vladimirov Department of Maxillofacial Surgery,Faculty of Dental Medicine, Medical University - Plovdiv, Bulgaria Journal of IMAB - Annual Proceeding (Scientific Papers) vol. 17, book 2Introduction. The orthodontist treating patients withcase reports the potential of the open surgical technique forMaterial and methods. Three patients aged 13 to 20Results and discussion. All canines underwentConclusion. The described method of surgical palatally impacted canines, surgicalTreatment approaches are aimed at the canines correctand can be divided into preventive and surgical. Theand prevention of impaction is impossible surgical-Various surgical techniques for exposing palatallywindow; 4. tunnel extrusion, etc. Within the differentThe choice of a surgical approach still remains aquestion of personal preference for the surgeon andevidence in favor of one of the techniques (7, 8, 9). Additionalteeth are needed (10, 11).The aim of the present report was to demonstrate thepotential of the open surgical technique for stimulation ofMATERIAL AND METHODSThe teeth had different degrees of impaction in relation to thevertical and horizontal planes. Surgical exposure wasperformed before orthodontic treatment in one of the cases,treatment in the rest.

Due to the considerable tightness ofthe palatal mucosa surgical gingivectomy was planned toaccelerate the full eruption of the tooth (Fig. 4 - B, C).
