S E A S O N E D TADs Practitioner's Corner Dr. Terry McDonalD InTervIews Dr. MIchael chaffee on TaDs M Dr. McDonald Dr. Chaffee ost orthodontists are aware of the ability of temporary anchorage devices (TADs) to create absolute anchorage in anterioposterior (AP) tooth movement and the dramatic facial changes that can accompany these movements. Orthodontists may be less aware of the vertical control that can be achieved with TADs and the benefit that vertical control can have on the expression of anterior mandibular growth. Dr. Michael Chaffee, the interviewee for this issue of the Bulletin, shares his literaturesupported expanding wealth of knowledge on both AP anchorage management using TADs and also on how accurately placed TADs can assist in vertical control which additionally can aid in both AP and open bite corrections. Dr. Terry McDonald (TM): How and when did you begin utilizing skeletal anchorage devices in your practice? Dr. Mike Chaffee (MC): My small orthodontic study group had a meeting in Houston in 2001 and our invited speaker was Dr. Hyo-Sang Park of Daegu, Korea, who happened to be in Oklahoma for one year. My fellow study club members and I were absolutely fascinated with the added control that TADs were able to provide in the cases shown by Dr. Park. I began using them shortly thereafter, primarily in problem cases already in treatment that needed vertical control. Dr. Park became my long-distance mentor during the learning curve. At that time, insertion required a pilot hole the length of the screw, so an oral surgeon placed my TADs until they became self-drilling. I highly recommend that orthodontists place their own TADs because patient and parent acceptance is much greater when they do not need to be referred out, and because TAD insertion is less costly than with a surgeon. By placing TADs themselves, orthodontists will be more certain that they are placed in a location and at an angulation that will lead to ideal force vectors. TM: What are your preferred TAD design features? Figure 1. Simultaneous retraction and intrusion with .025" X .025" elastic thread (left) with .025" X .025" elastic thread and en-masse distalization and intrusion with .018" X .018" clear elastic thread (right). 30 MC: Like so many other choices we make regarding the devices we use in orthodontics, desired TAD features really come down to personal preference and I have used several brands over the years. I now use elastic thread almost exclusively in applying forces off of TADs, so for me a design with a hole that accepts elastic thread in size .016" X .016", up to size .025" X .025" is a must.
