Fragment reattachment using a technique with no preparation and an adhesive system associated with an intermediate composite with good mechanical properties can restore part of the resistance of the fractured tooth
BACKGROUND / AIMS Fragment reattachment is a procedure that offers advantages , such as preservation of tooth structure and maintenance of color , shape , and translucency of the original tooth .
The aim of this study was to analyze the reattachment techniques used to restore anterior teeth fractured by trauma .
Evaluation of the fracture resistance of reattached incisal fragments using different materials and techniques.
OBJECTIVES When coronal fracture occurs in anterior teeth , fragment reattachment can be a valid alternative to a direct restoration . The aim of this study was to evaluate the influence of the material and the technique used to reattach the fragment . MATERIAL S AND METHODS Eighty sound maxillary and m and ibular incisors were selected and r and omly divided into eight groups ( n = 10 ) . The incisal third of each tooth was removed using a saw machine . The fragments in groups 1 - 4 were reattached using resin-based material s : group 1 adhesive , group 2 flow , group 3 composite , group 4 cement ; in groups 5 - 8 , the same material s mentioned before were used but a bevel was also performed on both labial and lingual surfaces . Shear bond strength ( SBS ) was calculated by applying a load incisal to the reattachment line . A two-way Anova was used to evaluate the influence of material s and techniques on the SBS . RESULTS The technique used was statistically significant ( P < 0.001 ) , while the material was not ( P = 0.793 ) . CONCLUSIONS The choice of material seems to have no influence on the SBS , whereas a bevel performed on the labial and lingual surfaces can significantly improve the SBS of the reattached fragment
