Indiana University-Purdue University Indianapolis (IUPUI) / This investigation examined the relationships of preparation and resin material types in the reattachment of fractured anterior tooth fragments. A total of 44 extracted maxillary central incisors were tested. Statistical analysis revealed that no-handpiece preparation was as retentive as a 45° circumferential bevel (p <.01). In addition, the light-cured resin proved as retentive as did the chemically-cured resin (p<.01).
Also examined was the effect of the initial fracture angle on
retention of the fragment after reluting. Teeth fractured with an angle sloping cervically in a lingual-to-facial direction when viewed proximally were more retentive than other types of fractures when subjected to a lingually directed force from the labial (p L.OS).
