Tooth number 17 (Figure 5) was extracted with associated soft tissue due to extension of the lesion to the cemento-enamel junction.
In experimental groups (C, Z and T) the anatomic crowns of the teeth were sectioned perpendicular to the long axis, 2mm above the cemento-enamel junction, under continuous water cooling, and then the root canals were prepared for the posts placement.
Clinical loss of attachment measurement were made from the cemento-enamel junction to bottom of the sulcus.
After remnant soft tissue was removed, all teeth were sectioned (Minitom, Struers, Copenhagen, Denmark) perpendicular to the cemento-enamel junction and the roots were discarded.
Occurrence of root caries was assessed and root length, distance between cemento-enamel junction and root tip, was measured (mm).
As the implant patient demand for esthetic results continues to grow, this new material is especially ideal for patients with thin facial gingival tissue, when soft tissue migration occurs during healing process, or when the cemento-enamel junction is visible on adjacent natural teeth.
