A Randomized Controlled Trial To Compare The Histomorphometric And Clinical Outcomes Of Soft Tissue Augmentation At The Time Of Lateral Ridge Augmentation Procedures, Kenneth Liu

All ETDs from UAB

Guided bone regeneration (GBR) can be used to augment deficient alveolar ridges in preparation for dental implant placement. Mucogingival deformities can result from the periosteal releasing incision during GBR. This can be addressed by additional soft tissue augmentation procedures to increase the width of keratinized tissue and vertical soft tissue thickness, both of which have demonstrated clinical benefits around implants. The drawbacks of soft tissue augmentation following ridge augmentation include an additional procedure, increased patient morbidity, and less patient acceptance of treatment. In general, soft tissue augmentation can be performed at various time points throughout treatment, but literature on soft …

Midpalatal Suture Maturation Stage Evaluation In Young Adults, Anna Maria Betlej

All ETDs from UAB

Rapid palatal expansion (RPE) is a gold standard treatment for posterior unilateral and bilateral crossbites or limited buccal overjet in patients with constricted maxilla. Midpalatal suture fusion is a limitation for obtaining the skeletal results and avoiding dental side effects. It is generally believed that midpalatal suture interlock increases significantly after the pubertal growth spurt. However, in the literature there are reported cases of successful midpalatal suture split in older adults. Individual cone-beam computed tomography (CBCT) assessment of midpalatal suture maturation was proposed by Angelieri et al. Since RPE treatment approach is commonly used it is important to understand the …
