Upper anterior intrusion with mini-implants to correct anterior deep bite in a periodontally compromised class II malocclusion. Case report

The use of mini-implants has revolutioned biomechanics in orthodontics with better results as far as anchorage is concerned. We have no limits when using these attachments depending only on our imagination. Anterior deep bites in severe class II malocclusion patients are a common problem that causes orthodontists to focus therapy in biomechanics to eliminate the problem by extrusion of posterior teeth or intrusion of the anterior. In this case, we decided to correct the anterior deep bite by intruding the incisors using as anchorage two mini-implants. The case was compromised by periodontal disease with moderated loss of alveolar bone so we had to choose biomechanics with a stable anchorage to achieve our goals. In the end, the patient exhibited collateral effects that were solved successfully and the deep bite was eliminated with great results and stable periodontal health. Key words: Mini-implants, intrusion, deep bite.
