There are lots of systems out there, and most of them work well. However, mini implants have limitations and certain indications, and my real question is what are you using the mini implant for? What I mean is, do you plan on restoring that implant with a tooth, is it helping keep a denture in place, is it by itself or are there multiple implants being placed?Originally, mini implants were designed to be temporary implants to be used while healing took place with the final restorative plan using conventional sized implants. Nowadays, some companies have changed their implant surface coating with the design that they will be permanent -- Zest implants just released a study showing 10 year success rates that were quite high. However, mini implants should be reserved for certain indications, and in my opinion are best used for retaining a denture when conventional sized implants are cost prohibitive, there is inadequate bone, and/or when there is inadequate bone and the patient is trying to avoid bone grafting to allow for a large implant to be used.Mini implants used to restore a tooth is generally a poor decision -- the only teeth I'd ever consider restoring on a mini implant are the smallest teeth we have that are in the least amount of function: lower incisors or upper lateral incisors (the small teeth just next to your two front teeth). Mini's just aren't design to take much biting force, so they won't last if you ask them to do too much work. Investing in a bone graft and a larger implant is a much more predictable long term solution. There are companies like Biohorizons, Nobel Biocare, and Straumann that have come out with 3.0mm implants that are very strong and can withstand long term use. These are just slightly larger than minis, but they will be a better long term choice by far. If you are using a mini to retain a denture, then you can be successful in a variety of ways, but my personal favorite are the Zest minis which allow for a locator ("snap") attachment to be used. This snap is the same one we place on regular sized implants so you can often get the same end result while saving money and avoiding grafting. Plus, these snaps can be changed out over time as they wear out or tissue height changes where most other mini implants are a single piece meaning nothing can be changed once they're in place. Also, I would recommend using more implants if you go the mini route. So in summary, if you're thinking minis, evaluate why you're thinking minis. If it's cost and you're looking for teeth, you may want to consider saving for the better more permanent option of a larger implant. If it's a denture retention issue, ask your dentist or surgeon about the system before you commit to make sure you're getting the best design for your situation.
