What is a contraindication for performing an apically positioned flap?

The primary reason esthetics is a contraindication for performing an apically positioned flap is that this surgical technique can potentially result in a less favorable appearance in the gingival tissue. When the flap is repositioned apically, it may leave an area of exposed root surface, which can lead to not only sensitivity but also a compromise in the aesthetic appearance, particularly in the anterior regions of the mouth where smiles are more visible.

In contrast, factors such as patient age, gingival recession, and bone density do not inherently disqualify a patient from undergoing this procedure. For example, while younger patients may heal faster positively influencing surgical outcomes, age in itself is not a sole hindrance to the use of an apically positioned flap. Similarly, gingival recession may actually be an underlying reason for considering this type of flap to cover exposed root surfaces. While bone density considerations are important in implant procedures and overall treatment planning, they do not pertain directly to the decision-making process regarding whether to perform an apically positioned flap. Thus, the concern for maintaining a pleasing aesthetic outcome makes esthetics the correct contraindication in this context.
