Fig. 9-78. Holes are prepared with various types of burs.

Fig. 9-79. A Vitallium spiral-shaft implant (Chercheve) is placed in the right bicuspid region.

Fig. 9-80. A titanium spiraled (Muratori) implant is placed in the first molar region.

Fig. 9-81. A, An aluminum oxide (synthetic sapphire method of Sandhaus) implant (also called CBS bone screw) is placed in the second molar area. B, All three implants (Figs. 9-79 to 9-81, A) are seen in their proper positions.

the bridge fitted over them with no interference, the implants on the left side were inserted one by one. Here a Michel Chercheve narrow ridge implant (Fig. 9-83) and two Linkow vent-plants (Fig. 9-84) were used. Once again, and in the same manner as on the right side, holes were made inside the tissue-bearing surfaces of the pontics to house the protruding implant shafts (Fig. 9-85). The jaw now had three implants in each side (Fig. 9-86). The bridge was again tried over all the implants (Fig. 9-87) .

At this point, if the implant shafts on both sides of the jaw are parallel, interchangeable gold copings are placed over them. The bridge is tried over them and then removed. Cold cure acrylic is placed inside
