Iris Publishers - Online Journal of Dentistry & Oral Health| A Novel Technique for Orthodontic Gap Closure with Access through the Maxillary Sinus
Authored by Brigitte Wendl*, Abstract Background: Orthodontic gap closure is an important alternative to prosthetic restorations on implants. However, the presence of bone of sufficient quality and quantity is critical to proper tooth movement in the maxilla, especially in patients with a markedly enlarged maxillary sinus. These two case reports demonstrate a new method to facilitate bodily gap closure through the maxillary sinus with the help of an interdisciplinary surgical approach (sinus lift and bone augmentation). Material and methods: Two patients requiring orthodontic gap closure in regions with a markedly enlarged maxillary sinus and an area of atrophic bone that needed augmentation were treated with pre-orthodontic sinus lifts using the fully resorbable Guidor easy-graft Classic (Sunstar) augmentation material. Superelastic tension springs and miniscrews were chosen as orthodontic appliances. Target parameters were evaluated preoperatively, directly po...
