It is interesting to me that the treatment goals for esthetic dentistry and for orthodontics appear to converge. In restorative dentistry and prosthodontics, much attention is presently being paid to the vertical dimension of tooth display, ie, the amount of maxillary incisors that is showing when a patient is engaged in normal conversation. Dr Zachrisson, having listened to your lectures on esthetics of tooth display in orthodontic patients, I realize that you have changed your treatment strategies for corrections of deep overbite situations in recent years. Thus, you apparently have stopped using active mechanical intrusion of maxillary incisors in your deep overbite cases, and instead intrude the mandibular incisors. Does this mean that you consider the intrusion of maxillary incisors by mechanical means to be an undesirable orthodontic treatment strategy for handling deep overbite cases?
