1. Soldering info for Rob
Regarding the comments on electrosoldering - you can take a Rocky Mountain 660 spot welder and using the two white receptacles on top - insert a carbon tip electrode in one receptacle and insert a soldering turret (Ormco used to make these) into the other receptacle. Heat setting is "S" or #1. Then you can put premeasured soldering electrodes (ormco) in the turret . The problem now is that Ormco no longer make the turret.
Electrosoldering has so many advantages over other techniques in my opinion: premeasured electrode means you get exactly the correct amount of solder each time; heat application is fine adjusted so that overheating is not a problem; solder joints are not carbon covered and require very little finishing. I teach a segment on this subject to junior dental students and they consider it a revelation to find electrosoldering after using the "torch".
There is a new ortho lab call Blue Star Dental (866-231-7336) that has created a new soldering turret at my request using the services of a machine shop. The genius of the turret is the fact that the solder is held in the correct position, in the correct amount so that your full attention can be devoted to the carbon tip heat application. The turret is pricey due to custom fabrication but it makes soldering downright simple. Hope this info will be helpful . Don't forget to spot weld all joints prior to solder & use plenty of flux.
Do you know of any way of filling the bracket slots to it maximum? I have an adult patient whom I have placed an temporary acrylic prosthetic tooth in an anterior edentolous area. I have fully bonded the patient and have also bonded the prosthetic tooth. I use a .022 slot bracket, and have placed a .021 x .025 wire. However, the patient does not like the "jiggling" of the prosthetic tooth. I have also ligated the prosthetic tooth to the adjacent teeth, yet there is still some minor movement. I have also attempted to make the slot smaller by squeezing the bracket wings together. I am not sure if a .022 x .025 wire is made, and if it is, what type of fit would we get in the slot. Any suggestions will be greatly appreciated.
It must be my year for families to relocate overseas. I have a former patient, now married with 7 children, ages 3 to 14, moving to Medan , Sumatra , Indonesia after the first of the year. They are missionaries and will be over there at least 3 years. They have been spending a few months here with family before they leave and have brought a couple of the kids in to be checked, none of the children are in treatment. The oldest has a high angle, moderate dental, severe skeletal Cl. II malocclusion with anterior open bite, cross bite and severe crowding. A very difficult case. The 7 year old is developing severe crowding. I get to see a couple more in the next week or two. Would anyone know of an orthodontist with university training living on Sumatra ? Mom thought that there were one or two orthodontists in Medan but none are listed in the 2004 Orthodontic Directory.

My son is in Cub Scouts, and his buddy's dad is the group leader. The other day, I offered to do a field trip of sorts at my office for his ?pack. I did this, of course, before really thinking about what I would do with them.
I have heard about having kids mix up some alginate in a cup, making an impression of their finger, then pouring it up in stone, which could be fun/interesting. That aside, I would be grateful for suggestions about how to entertain and possibly educate a group of 10 year olds for an hour. We had some really good seminars on bone metabolism back in my residency, but I'm not sure how that would go overů
My deadline is not until the New Year, so I'm not panicking yet, but would still appreciate your thoughts.
Dear ESCO Members,
I write this e-mail very reluctantly, as I believe this forum should be a platform for debate of issues, and not a vehicle for selling products. As one of the owners and founder of Oasys, I could certainly inform you of all the virtues of our multi office technology as well as our data conversions, but will leave that to others with "no ax to grind". I do invite anyone who is interested to contact me for a discussion of these and other topics @ email@example.com or 800-528-2978 ext. 226.
