 All patients will be referred for limited field cone beam computer tomography to assess presence of adequate bone volume at the area of interest, according to standard clinic protocol. Alginate impressions will be obtained to fabricate diagnostic stone casts. A vacuum-formed stent will be manufactured in the laboratory to offer fixed reference points for longitudinal probing measurements, and a radiographic stent using polyvinyl siloxane interocclusal record material will allow standardized positioning of the radiographic holder to obtain periapical radiographs with the same projection geometry.
