Orthodontic miniscrews for the correction of a severe gummy smile in a class II malocclusion case

A gummy smile (GS) has an impact on one’s appearance as well as psychological well-being because it typically lowers self-confidence, which causes one to hide or restrict their smile. The objective of this work is to highlight the importance and effectiveness of non-surgical treatment of gingival smile using miniscrews through a clinical case. A 34-year-old woman patient was referred to the orthodontic department of the Rabat Center for Dental Consultation and Treatment (CCTD-Rabat). She wanted orthodontic retreatment for excessive gummy smile in the anterior area. She was in good health, with no notable family or medical history. There was a significant deep bite, and she had already received an extraction orthodontic treatment, was not well controlled. In order to achieve a nice smile, surgical therapy is frequently used. However, sometimes patients refuse surgical intervention, in which case a different approach needs to be taken into account. Miniscrews and other skeletal anchorage systems are now commonly used to treat severe malocclusions that need to be addressed surgically. Miniscrews were used in this case to correct the gummy smile, interradicular miniscrews were placed in the upper anterior areas between incisors and canins. The gummy smile was improved and the overbite was reduced from 7.5 mm to 1.7 mm due to upper incisor intrusion. Miniscrews are a useful and practical choice, in the correction of a severe gummy smile. However, for long-term stability ; proper alignment and torque of the maxillary incisors were crucial.
