Invited Lecture:
Premolar transplantation versus orthodontic space closure in the anterior maxilla: an orthodontic perspective.
Abstract:
Patients with missing maxillary incisors often require interdisciplinary treatment planning and coordination of different specialists. In growing patients there are limited possibilities to substitute a missing tooth, because it should adapt to the dentofacial growth changes. Therefore, an orthodontist is included to evaluate these changes regarding indications for autotransplantation of premolars and orthodontic space closure. Selection of a donor premolar, pre-surgical orthodontics to open adequate space at the recipient site and achieving a stable occlusion including space closure at the donor site are important orthodontic considerations. Mesialisation of a lateral incisor is a valid alternative to premolar transplantation and it requires a comprehensive orthodontic treatment planning and biomechanics.
In the presentation, the indications for orthodontic space closure and autotransplantation of premolars following trauma to maxillary incisors in both primary and permanent dentition will be discussed. A very important aspect is orthodontic repositioning of the transplanted premolar or the lateral incisor to achieve the best match of the final restoration to the missing central incisor. It will be shown during the lecture including limitations of both options. The long-term outcomes of treatment using these methods will also be presented, based on various clinical cases and the authors’ own research. The summary of pros and cons of both treatment alternatives aiming at strengthening clinically relevant decisions including patients’ perspectives will conclude the presentation.
