Expanders

Bone and sinus expanders

The BONE EXPANDER KIT ZIACOM® contains the necessary instruments to perform bone expansion procedures for the placement of both single and multiple continuous implants and sinus elevation procedures with transcrestal technique.

Bone expanders

For clinical situations where bone tissue is deficient, ZIACOM® has designed the EXPANDER KIT, which is used to increase bone volume and quality by compressing and expanding the bone cortices.

ZIACOM® EXPANDERS have a threaded morphology that will facilitate their use with maximum precision and control, producing functional stimuli that favourably modify bone density.

Features

  • Head compatible with ratchet 4×4 mm
  • Length of active part of 14.5 mm
  • Cylindrical shape, which avoids a wedge effect on the bone
  • Millimeter laser marking
  • Atraumatic tip; not harmful to neighboring anatomical structures

Bone expander for sinus elevation:

The ZIACOM® sinus lift bone expander is designed to atraumatically compress the bone tissue surrounding the sinus membrane, creating sufficient space for the placement of longer implants.

Features

  • Head compatible with a 4×4 mm ratchet
  • Length of active part of 14,5mm
  • Threaded design: facilitates instrument insertion and ensures optimal cortical compression
  • Millimeter laser marking
  • Atraumatic tip; it has a concave shape, which reduces the risk of perforation of the sinus membrane

Recommendations for use

Expanders are indicated to correct bone defects, since their use as a complementary technique to the placement of dental implants, will increase the volume and bone density allowing the correct three-dimensional placement of dental implants. Bone expanders can be used to achieve

BONE EXPANSION

From a surgical bed, the bone crest is gradually expanded, creating sufficient space for the placement of implants.

SINUS ELEVATION

Its use will compress the bone surrounding the sinus membrane, which will raise the floor of the maxillary sinus in an atraumatic way, allowing the placement of longer implants.

Advantages

  • Simple surgical protocol.
  • More conservative technique, as the bone is not removed by drilling, but compressed laterally.
  • Compaction of bone around the implant which favors osseointegration.
  • Precision and control at the moment of the insertion of the implant.
  • Reduce the use of burs.
  • When the expanders are inserted in a threaded way, a bleeding is produced that will favor the osseointegration.
  • They can be used for the placement of different dental implant systems.

Instructions for use

  • Bone expansion for the placement of single and multiple continuous implants (1)
  • Transcrestal sinus lift (2)
  • Expansion of the crests in bone type II, III and IV (3)
  • Bone expansion in bone type I in combination with conventional drill system (3)

(1) Expansion of bone ridges of minimum 3.00 mm in diameter, 8.50 mm in length and maximum 6.00 mm in width and 13 mm in length.
(2) Elevation of the sinus membrane to a maximum of 4.00 mm, having a minimum bone crest of 5.00 mm
(3) Bone density classification according to Lekholm and Zarb (1985).
