Another case shows how clean and concise the groove must be, fig. 67. A special depth guage instrument is used to check the entire depth of the groove, fig. 68. The properly designed and sized blade is bent with two titanium tipped pliers so that it will fit passively into the groove, fig. 69. It is carried with a carrying instrument, figs. 70, 71, to the groove, and tapped into position, fig. 72, and then sutured, fig. 73. The interocclusal clearance is carefully checked before sending the patient home, fig. 74. Sometimes, at the same visit plastic copings are inserted over the posts, fig. 75, to more rapidly fabricate the final prosthesis. After sufficient healing, fig. 76, the completed partial bridge is cemented in position, fig. 77, 78, and a final x-ray is taken, fig. 79.
