“…One of the most widely tried and trusted sites for insertion of miniscrews is the palate, [1][2][3][4] whose para-median zone has been found particularly suitable for this purpose as, among other reasons, it lacks nerves and blood vessels that could be easily damaged during miniscrew application. 5,6 Indeed, before the advent of miniscrews, this site was chosen for the positioning of onplants and subsequently osseointegrated dental implants.…”

“…Paik et al 16,25,26 introduced simple intrusion mechanics using an archwire incorporating a curve of Spee, conventional transpalatal arch, and miniscrew in the midpalatal area. Since vertical correction was achieved successfully, with an outcome similar to that observed following LeFort I maxillary impaction, they called the procedure ''slow impaction.''…”

A 20-year-old woman visited the office complaining of a gummy smile and lip protrusion. She was diagnosed with vertical maxillary excess without open bite and skeletal Class II hyperdivergent pattern. She refused the surgical-orthodontic treatment option, although she wanted to correct the gummy smile and retruded chin. Differential intrusion of anterior and posterior teeth in both arches was necessary to maximize the skeletal treatment effects. In the maxilla, one palatal temporary anchorage device (TAD), an archwire with an accentuated curve of Spee, and a transpalatal arch were applied. In the mandible, an archwire with a reverse curve of Spee and two vertically positioned TADs were used. These simple mechanics contributed to the effective intrusion of the total upper and lower arches, correction of the gummy smile, and mandibular counterclockwise rotation, offering an alternative to orthognathic surgery for this patient.

“…Parket al(2001), Xunet al (2004) and Kakuet al (2012) suggested that TADs are reasonable alternative for correction of gummy smile when surgery is unfeasible, such aswhen patient denies to be subjected to surgery. Though the benefit of TADs in treatment of gummy smile is underestimated in literature (Carrillo et al, 2007;Feldmann, Bondmark 2006;kurodaet al, 2007;Padhyayet al, 2008;Paik et al, 2007), the use of TADs for upper incisors intrusion was intensively reported during the last decades (Ohnishi et al, 2005;Deguchiet al, 2008). The reports have indicated that effective maxillary incisors intrusion was achievable; with minimal side effects and without much patient cooperation, by using TADs as a stationary anchorage mean (Carrilloet al, 2007).…”

Aim was to evaluate the usability of mini-screw (Temporary Anchorage Devices TADs), as an anchor unit (units), in the treatment of gummy smile associated with deep over-bite. The sample was made up of 15 adult gummy smile patients (2males and 13 females).Materials and Methods All patients suffered from increased anterior facial height. Pre-treatment and post-intrusion gingival smile line (GSL), which is the distance between cervical gingival margins of maxillary central incisors and the lower border of the upper lip during smiling, was measured in millimetres using a digital calliper. Four TADs were used for each patient: two anterior TADs that were inserted between the roots of lateral incisors and canines; and the other two TADs were inserted posteriorly, between the roots of 2nd premolars and 1st molars. The anterior TADs were used as anchor units for the intrusion of upper anterior teeth, while posterior TADs were used for en-mass retraction. Pre-treatment and post intrusion lateral cephalometric radiographic measurements were taken for statistical inferences. Statistical analyses were carried out using Wilcoxon signed rank test. Statistical analyses revealed significant reduction in GSL and overbite.Results Radiographically, there were significant changes in the vertical and antro-posterior positions of upper anterior teeth, but no significant changes have been noticed in the vertical position of upper or lower posterior teeth.Conclusions The findings of the present study indicate that gummy smile which is mainly due to maxillary dentoalveolar overgrowth can be treated effectively with intrusion using anterior TADs, particularly in case of divergent face. The findings also indicate that anterior and posterior TAD scan provide absolute anchorage for treatment of deep overbite, and increased overjet.
