Placement of class ii composites

I refer to Alix Furness's letter on the placement of Class II composites without the use of a matrix band (December Dent Update 2014; 41: 933). I was attracted to the article because of its heading but, as I continued to read it, I realized that the technique alluded to was unconventional to say the least.

I was intrigued since I, too, have been qualified for well over 30 years and have been to many hands-on courses for placing posterior composites, including some presented by Professor Burke. I have spent a professional lifetime trying to perfect my technique and have never attempted doing them free-hand, much less had it recommended by anyone as an evidence-based procedure.

I presume that there is a reason for this.
