Production of Surgical Stents

i-station α Surgical Stents

It is a surgical stent to accurately place i-station α on an appropriate location. The location is determined by overlapping CT and digital dentition data ( or plaster model data). Lingual twin brackets must be installed on the first molars. (We can design and produce them if necessary.) i-arm α is processed accordingly. i-arm α can be set on the same day of screw installation making it possible to apply force immediately.

i-platform α

Depending on the thickness of palatine bone, i-platform α II or i-platform α III is chosen.

i-platform α Ⅱ

i-platform α II is chosen when the palatine bone is thick and no complicated mechanics are required. It is consisted of 3 attachments: Front Attachment, Center Attachment, and Back Attachment.

i-platform α Ⅲ

i-platform α III is chosen when the palatine bone is thin and complicated mechanics are required. It is fixed with 3 to 4 screws. Just like i-platform α II, it is consisted of 3 attachments.

i-arm α

i-arm α is a unit that is installed on the Attachment to implement the movement.

i-arm α Wire

Used on the Front Attachment

Intrusion of the anterior teeth

Lateral movement of the anterior teeth

Mesialization of the molars

Used on the Center Attachment

Maximum Anchorage

With the first molars being fixed with ligature wires, retraction can be performed with maximum anchorage using elastics.

Intrusion of molars

Molar intrusion is achieved by placing palatal arches on the molar brackets along with the elastics.

Used on the Back Attachment

Distalization

Distalization of the first molars can be achieved by extendingthe arms backwards and using elastics.

i-arm α CS

Distilization

Effective distalization can be performed when canine and the first molar are pulled simultaneously by using elastics or other materials.

i-arm α Plate (S-Gwire)

A number of teeth movements can be achieved by using resilient G-wires on i-arm α Bracket.

Expansion

S-Gwire is an s-shaped GUMMETAL wire（Ti-Nb based beta titanium alloy wire that is very resilient）, which makes it possible to perform the expansion of molars.

Constriction

S-Gwire is an s-shaped GUMMETAL wire（Ti-Nb based beta titanium alloy wire that is very resilient）, which makes it possible to perform the constriction of molars.

Intrusion

S-Gwire is an s-shaped GUMMETAL wire, which makes it possible to perform the intrusion of molars.

Extrusion

S-Gwire is an s-shaped GUMMETAL wire（which makes it possible to perform the extrusion of molars）.

i-arm α Plate (T-Gwire)

Distalization

T-Gwire is a T-shaped G-wire that is used on the Back Attachment for distalization.

Setup Models

i-system set up
maxillary and mandibular lingual cores +G-wire

By superimposing the digital data of the upper and lower dentition and the CT data, the final occlusal state of the dentition with the root direction combined is digitally produced.
Brackets are aligned with a straight arch wire (steps can be included in some cases) that conform as closely as possible to the final occlusal model. The Carriers which can be positioned precisely at the planned bracket locations are fabricated. Optionally, lingual arch wires can be provided. The material of arch wires are GUMMETAL 0.085×0.025 inches.

The lingual brackets we use are Clippy L (.018”Slot) and the labial brackets are Clippy C (.022”Slot) from TOMY, Inc. A lingual twin bracket from JM Ortho is used on maxillary 6.
