An alternative sinus floor elevation procedure: trephine osteotomy.

Today, the sinus floor elevation procedure is not only being used on a routine basis, but clinicians are reporting high success rates. The sinus floor graft has become an important option in the treatment of the edentulous posterior maxilla, where vertical bone height is less than ideal. A review of maxillary sinus floor elevation as an integral part of restoring the posterior maxillary is discussed.

Indirect impression technique for multiple cast dowel and cores facilitated with three putty indexes.

Fabrication of multiple direct cast dowel-and-core patterns is time-consuming and difficult because the clinician must assess the adequacy of the reduction of the final restoration and the path of insertion for the patterns. This article describes a technique for making impressions of multiple endodontically treated teeth for the indirect fabrication of cast dowel and cores, which are waxed up via three putty indexes obtained from the diagnostic waxup. This enables clinicians and technicians to communicate in a manner that facilitates predictable and consistent prosthetic therapy.
