1. Re: Damon Brackets
Transbond XT by 3M was recommended for bonding the D3, since they had problems with Enlight (Ormco's light cure adhesive). I believe D3 clear has similar problems with the spirit, and all the plastic brackets. The metal D3 should be much better than the clear D3. Metal D3 is available only for the lower arch.
In my office we use self ligating brackets almost exclusively for more than six years. Initially, I tried all the products on the market, and I continue to try new products in order not to miss a good new one. After the testing phase we decided to use Speed brackets, and I would like to explain why.
Damon I and II were very bulky brackets with very small interbracket distances. In cases with severely rotated lower anteriors the size of these brackets often impeded correct placement, and furthermore, because of the small interbracket distances these brackets produce high force levels even with low diameter leveling wires. Additionally, the opening/ closing mechanism was a hassle and we observed an unacceptable rate of spontaneous openings between appointments with the consequence of delayed treatment time.
The Damon III is only minimally narrower than it's predecessors, still with relatively short interbracket distances and an only minimally improved opening/closing mechanism. I also observed a high rate of breakage and detachment of the metal slot from the plastic part, too. The Speed bracket instead is the narrowest bracket on the market, as far as I can overview, offering large interbracket distances and a very elastic, gentle force-system in the leveling phase. In children and adolescents, I can place a 019x025 steel wire normally after 3 months of leveling, and in some cases even earlier, which is obviously due to this mechanical advantage in combination with low friction and a NiTi spring clip forgiving small levelling deficiencies. Typical total treatment time for class I/ non -extraction in adolescents is 8-9 months, for extraction or class II 12-15 months. The breakage rate is very low because the bracket comes with a sand-blasted, highly retentive mesh base. The opening/closing mechanism is highly reliable, if care is taken to close the spring clips precisely, and control in all planes of space is indistinguishable from larger siamese brackets.
Finally, the Speed bracket is costs round about half the price of the Damon bracket. So I really do no not understand why so many colleagues spend more money for an inferior product - is it because of the overwhelming marketing efforts, which want to make the profession believe that all orthodontic problems could be resolved by simply switching to another bracket?
So my modest proposal for those who are searching a reliable self ligating bracket: try the Speed bracket, this will probably be the solution for the problem. (No financial interest, despite my enthusiasm!)

We are using D3 at that time in about 150 cases. According to the EU Ormco-staff there is now (since AAO in SF) a chemical binding to the mesh with blugloo. Since then the number of broken brackets decreased a bit and the glue is now on the bracket. But this is worse than before: rebonding is almost impossible. We have the same problem with the DAmon-hype in our area.
There is a swedish bracket by gestenco called oyster. It is or was sold thru GAC and/or american ortho. Has anybody any experience?
So refreshing to hear the problems others have had with D3 brackets. I echo the thousands of dollars in costs, the broken brackets, the flaking off of supposed ceramic, broken metal doors... let alone the embarrassment for a substandard product. john _________________________________________________
