proper occlusion had been established, fast-setting acrylic was placed into the holes and the splint was placed over the teeth and implants (Fig. 9-18). It was quickly removed and replaced every 20 seconds or so. This guaranteed that the holes exactly accommodated the implant shafts, yet prevented the acrylic from locking to the implants themselves.

After the acrylic set, all excess on the tissue-bearing surface was removed and the surface was polished with the splint outside the mouth. (When a patient has extremely soft tissue, the splint may be lined with a soft material, such as a rubber base, or with a soft tissue conditioner.) The temporary splint was then cemented into place with a temporary cement (Fig. 9-19). This cement should be used only inside

those areas of the splint intended to cover the natural tooth abutments. Otherwise, because the implant
