Hiossen MS System
The MS System is a mini one-piece implant for situations where there simply is not width for a standard one, most often a narrow lower ridge at the front of the mouth.

What a narrow ridge means
Bone shrinks in width as well as height after teeth are lost, and the front of the lower jaw is often the narrowest ridge in the mouth. Hiossen describes the MS narrow ridge implant as a mini unibody implant ideal for narrow spaces such as the mandibular region, with an abutment head shaped and sized to minimise the need for trimming.
At ∅ 2.5 mm there is not enough material for a separate abutment and screw, so the implant is machined as a single piece. Hiossen recommends an insertion torque of no more than 30 Ncm, a modest figure that reflects how little material there is to work with.
What a one-piece mini implant will and will not do
A one-piece mini implant is not a small standard implant. Because the head is fixed at placement, its angle cannot be corrected afterwards, and a crown must generally be cemented rather than screwed on. These implants are used principally for denture retention and for restricted spaces, not as foundations for heavily loaded fixed bridgework.
If a practice is presenting mini implants as a cheaper equivalent to standard implants for fixed teeth, that is a misrepresentation. Ask directly whether you have enough bone width for a standard implant, and what widening the ridge would involve if you do not.
The alternative worth asking about
Where a ridge is too narrow for a standard implant, the other route is to widen it, a ridge augmentation graft, followed by healing, then a conventional implant. That is more surgery, more time and more cost, but it ends with a standard two-piece implant. Whether that is worth it depends on what you want the implant to do. It is a fair question to put to your dentist.
Questions worth asking your dentist
- Do I have enough bone width for a standard implant?
- If not, what would ridge widening involve, and what would it cost?
- Is this for denture retention or for a fixed crown?
- What length are you planning, and why that one?
- Since this is one-piece, how will the crown be attached and can it be removed later?
- Will you record the diameter, length and reference number in writing?
