Abstract
 
Nowadays, there is controversy regarding the impact that the orthodontic treatment has on the periodontal tissues, particularly on those patients with a thin biotype even on health conditions. Given this, the recommendation is to keep the orthodontic movements within the range of the alveolar bone. The loss of the vestibular bone plate is a challenge to the operator since the vascularity frequently is compromised and this is fundamental for the success of treatment. This paper describes the case of a prognathic patient who was under orthodontic treatment; the subject had the lower incisors in a retroclined position, a thin biotype and generalized loss of the vestibular alveolar bone plate in the anterior region of the lower arch. The treatment consisted of a bone graft using the Subperiosteal Minimally Invasive Aesthetic Ridge Augmentation Technique (SMART) along with Plasma Rich in Growth Factors (PRGF), all this with the aim of favor regeneration and angiogenesis. Passing six months, the patient presented bone gain visible in the cone beam study; the benefits and limitations of this approach are discussed.
