Hiossen LODI
LODI is built for one job: making a loose denture stay put. It uses the LOCATOR attachment family, and its diameter range is broad enough to cover both narrow and standard ridges.

The problem it solves
A lower full denture is the hardest prosthesis in dentistry to keep still. There is no palate to create suction, the tongue lifts it constantly, and long-term denture wearers often have very little ridge left to grip. People stop eating certain foods, and speak carefully to avoid it moving.
An overdenture system places implants in the front of the jaw and fits attachments to them. The denture clips on. It still comes out for cleaning, and it still rests partly on your gums, but it no longer moves while you eat or talk. For many people this is the single largest quality-of-life improvement dentistry can offer them.
The diameter range is the notable part
LODI spans 2.4 mm to 4.9 mm. That breadth matters: the narrowest sizes serve patients whose ridges have resorbed severely, while the wider ones behave as conventional implants. Hiossen positions the system as making overdenture treatment available to patients who might otherwise be told they lack the bone for it.
The LOCATOR attachment
LOCATOR is an attachment system made by Zest Dental and used across many implant brands, it is not exclusive to Hiossen. R-Tx is its later generation. A stud on the implant engages a nylon insert in the denture, and the insert comes in several retention strengths so the grip can be tuned.
Because LOCATOR is an industry-wide standard, replacement inserts are widely available regardless of which implant brand you have, a genuine practical advantage.
The nylon retention inserts are wearing parts. They typically need replacing every one to two years depending on use, each time a short appointment with a modest fee. Nobody hides this, but patients are often not told it up front. Ask what replacements cost at your practice before you commit, and factor a decade of them into your comparison.
Questions worth asking your dentist
- How many implants are you placing, and why that number?
- Which diameter suits my ridge?
- Will my existing denture be adapted, or do I need a new one made?
- How often will the retention inserts need replacing, and what does each cost?
- Would fixed teeth be possible in my case, and what would that cost instead?
- Will you record the implant diameters, lengths and attachment type in writing?
