Expander

Personalized objective

To reverse the process of bone loss by remodelling the architecture of bone tissue both quantitatively and qualitatively in three dimensions, to improve bone density through direct physiological functional stimuli, with the application of an atraumatic technique of maximum control and the use of ZIACOM threaded expanders.

Expander

Specific objectives

Bone expansion

Width bone gain, that allows the correct position and axial inclination of the implants and sufficient bone volume.

Bone sinus lift

Bone height gain to facilitate favourable inter-maxillary relation and normalization of intraoral relations.

Lateral bone condensation

Improvement of the density and consequent bone quality, achieving an increase in the support surface and therefore greater resistance to the load.

Technique

Minimally invasive longitudinal flaps of total thickness without tissue discharges. Lateral corticomias, without lateral bony discharges or fractures of lateral discharges. Use of Ziacom threaded expanders.

The bone expanders developed by ZIACOM limit surgical trauma and allow effective measured and progressive control of expansion.

Clinic features:

Only a lance drill is needed to start the procedure. Being able to do without in the protocol the intermediate milling using cortical drill and tap in bone type D2.
Thanks to its excess vascularisation, in bone type D3 is not necessary to use more than a lance drill and irrigate well the osteotomy .
The excess bone that is compacted in the neoalvéolo can be used for the design of the threads of the expanders.
In type D4 bone, since it has a lower percentage of bone tissue, it is possible to achieve tricortical anchorage. With Expander No. 6 we can use larger diameter implants and from 2 to 3 mm cortical crest onwards we can use instruments to insert 4.8 mm implants.
The specially designed Expander No. 7 allows for sinusual atraumatic sinus lift, preventing bone board fracture.

Benefits

Practically atraumatic use
Dilation of fine crests, increasing thickness without bone loss.
Bone compacting around the implant, favouring osseointegration.
Perfect control of the implant insertion axis during the intervention.
Reduces the use of drills, avoiding their wear and tear and extending their useful life.
Threaded progressive introduction produces bleeding, favouring osseo-integration.
The control of the manual or contra-angle hand expander minimizes the risk of lateral fenestrations in the vestibular area of the compact upper maxillary bone.
Its application is suited for different implant systems.

The ZIACOM Expander Kit contains atraumatic threaded expanders, designed to reverse the bone loss process by reshaping the tissue architecture in three dimensions: quantitatively and qualitatively. They improve bone density with an atraumatic technique of application of direct physiological functional stimuli, always controlled by the professional. With their atraumatic threaded design they limit surgical damage and allow for progressive and measured expansion. The kit includes lance drill, osteotome disc, 12 expanders, insertion keys, ratchet and a concave active apex expander with sinus elevator function.
