[Loss of permanent upper incisors--orthodontic treatment].

Abstract

After loss of permanent central incisors the treatment of choice could be either orthodontic closure or maintenance of the gap for a replacement-prosthetic, autotransplantation or implant. Cases suitable for orthodontic closure are Angle C1 I space deficiency cases and some C1 II cases, all of these requiring normal size and shape of the lateral. C1 III cases, cases with completely developed ideal occlusion and cases with excess of space are unsuitable for orthodontic closure, as are small pegshaped laterals. Different treatment alternatives are presented, illustrated with treated cases. When one or two central incisors are missing, there will be no treatment alternative giving a 100% satisfactory result. Orthodontic closure, however, proves to be a favourable solution, concerning both long-term prognosis, esthetics and function.
