mini-implant-logo

The MiNi Implant is used when a standard implant is too large for the surgical site. Most commonly, the MiNi is placed in the lower anterior or congenitally missing laterals.The MiNi Implant is manufactured with XPeed® S-L-A surface treatment for faster, stronger and safer integration, and is available in 2 diameters and 5 lengths. There is an 11 degree tapered connection between the abutment and the fixture, a 1.7mm hex used to engage the system for non-rotation purposes,and 1.4 diameter abutment screws to secure the abutment to the fixture.MiNi Implants are designed to be placed sub-crestal for optimal esthetic results.

MiNi, but Mighty

MiNi was designed for convenience with better reliability. When compared with company A, MiNi Ø3.0 has similar compressive strength, but Ø3.25 showed much higher strength value on the thin wall area of the fixture.

Fixture Length and Drill Marking

rachet-connect

The platform line of the Handpiece Connector or the Ratchet Connector must be flush with the fixture platform.

When using the Ratchet Wrench, do not use an excessive torque as it can lead to a failure of internal structural damage to the fixtures. It is not recommended to exceed the maximum torque of 75N·cm.

mini-lenths

The actual lengths of MiNiTM internal fixture is 0.5mm shorter than the depth markings of a Shaping Drill.Therefore, the fixture will be placed 0.5mm under the crest naturally.

Case Study

Fig 2. Flap was elevated and two osteotomy sockets were made for 3.0mm MiNi fixtures. There was enough bone left in labio-lingual area for slim fixture.

Fig 6. Provisional restoration was made chair side. Due to the smaller diameter of fixture and abutment, the prosthetics will have a natural emergence profile.
