Sinus floor elevation with osteotomes.

This article describes a new methodology for augmentation of the bone at the sinus floor that is less invasive than previous techniques. This procedure is called the osteotome technique. Two different applications of the osteotome technique are described. First an implant site is created in a location that previously had inadequate bone for immediate fixation of an implant. In a second surgical step additional augmentation of the bone is carried out when the implant is inserted. This case report provides details, from the original ridge defect with 1 to 2mm of bone under the low sinus to the final esthetic crown restoration on a 5 x 13-mm external-hex screw implant that is supported by newly generated bone.

The osteotome technique: Part 4--Future site development.

Previous articles in the Compendium (February 1944, April 1944, and June 1944) described the use of osteotome hand instruments for maxillary implant surgery. The osteotome procedures that were introduced compressed soft maxillary bone, widened narrow ridge segments (ridge expansion osteotomy [REO] technique), and elevated the sinus floor for immediate implant insertion (osteotome sinus floor elevation [OSFE] and bone-added osteotome sinus floor elevation [BAOSFE] surgery). This article presents an improved method of creating sites with osteotomes under a low sinus when there is insufficient bone for immediate fixation of implants. In addition, a new means of intruding the ridge crest with larger osteotomes to create broader areas of sinus floor elevation, known as the future site development (FSD) procedure, is outlined. A comparison of FSD with current types of sinus floor surgery is detailed. The advantages of combining FSD with periodontal surgery, other regenerative procedures, and tooth extraction is presented. The author concludes that FSD surgery is a suitable means of altering the ridge to create implant sites for staged implant placement.

The osteotome technique: Part 3--Less invasive methods of elevating the sinus floor.

Previous articles in The Compendium (February 1994, April 1994) described the features of the osteotome technique. In the initial article, a procedure that uses osteotomes to elevate the floor of the sinus, called the osteotome sinus floor elevation (OSFE), was mentioned. This article provides details and case reports on the OSFE. An enhanced version of the OSFE in which bone is added to the osteotomy will also be presented. The author concludes that the OSFE and the bone-added OSFE techniques are suitable means of altering the floor of the sinus so that in many patients, longer implants can be inserted in a less invasive manner.

A new concept in maxillary implant surgery: the osteotome technique.

This article reviews the limitations of drilling into soft bone to place endosseous implants. Differences among bone types and the anatomy of the maxilla are described. The osteotome technique, which is a new method of placing implants into maxillary bone without drilling, and the rationale for two other procedures, the osteotome sinus floor elevation and the ridge expansion osteotomy, are detailed. How osteotomes conserve osseous tissue and may improve bone density around the implant is also discussed. A pilot study that shows excellent results with several types of press-fit implants using the osteotome technique is provided. The author concludes that the osteotome technique is superior to drilling for many applications in soft maxillary bone. Furthermore, the osteotome technique allows more implants to be inserted in a greater variety of sites during a routine office procedure.

The osteotome technique: Part 2--The ridge expansion osteotomy (REO) procedure.

A method of performing an osteotomy in the maxilla using hand instruments was recently introduced in The Compendium (February 1994). This new procedure is called the osteotome technique. Part of this previous article described a means of placing implants in locations that are too thin to permit the use of standard implant drills. A bone enlargement technique, called the ridge expansion osteotomy (REO), that allows the surgeon to widen the ridge in a routine office procedure was also introduced. This article provides additional details about the REO, including an analysis of the advantages of the REO over other methods of ridge expansion. Clinical cases are presented that show the suitability of the REO for anterior and posterior locations, and the effects of the REO technique on implant angulation and esthetics are discussed.
