For patients with agenesis of one or both maxillary lateral incisor/s the question whether orthodontic space closure with extensive recontouring of the six anterior teeth by a combination of grinding and veneering is preferable to space opening and implant-borne crowns has not been answered yet. Less favorable long-term esthetic and periodontal outcomes have been reported for implant-supported crowns and thus the pendulum has swung towards the space closure side. The authors will present the outcome of two clinical studies with consecutively treated patients of their private office and critically discuss them not only in the context of the existing orthodontic literature, but including relevant interdisciplinary scientific evidence on the topic as well.
Evaluate the pros and cons of either orthodontic space closure or implant-borne crowns replacing congenitally missing maxillary lateral incisors from different interdisciplinary standpoints.
Appreciate the impact of the latest developments in periodontics, implantology and prosthodontics on the esthetic and periodontal outcome of single-tooth implants in the anterior maxilla.
Understand the importance of mutual decision making in the treatment planning process for patients with agenesis of maxillary lateral incisors.
