However, compared with labial
orthodontics, excessive lingual inclination of the maxillary anterior teeth and vertical and horizontal "arched effect" of dental arch easily appeared in the space closure stage during lingual orthodontics, because of large variability of anterior tooth lingual surface, small effect of bracket spacing on the rigidity and friction of the arch wire, and small bracket span between the orthodontic force point and the tooth impedance center (Lombardo et al., 2012; Long et al., 2013; Antoszewska-Smith et al, 2017).
The exact etiology is unknown, but a review of literature suggests that abnormally labially positioned tooth, very thin labial
plates, high frenal pull, and sometimes long-standing trauma may cause the dehiscence and fenestration defects.
between individuals), intra-individual variation, after Hanken and Wake (1993), and ontogenetic variation and to test whether variation in the number of anterior labial
tooth rows shows an ontogenetic pattern.
Upon gynecological examination, a thick and fibrous labial
adhesion was detected (Fig.1).
Se presento a consulta una paciente de 30 anos con gingivitis marginal generalizada, perdida de insercion localizada en incisivo central inferior derecho (diente 41) e insercion anomala del frenillo labial
The highest mean lesion measurement of 0.067 [+ or -] 0.020 was observed for ear pinna of UPM 1/14 followed by dorsal mean lesion of 0.052 [+ or -]0.017 for UPM 2/14 and the least measurement of 0.019 [+ or -]0.008 was observed at the labial
commissure of UPM 2/14.

These results confirm that not only intra-oral pressure is different in the inefficient labial
sealing, as well as the behavior of the perioral muscles (5).
The referring dentist reported the occasion of an accidental cervical labial
The force induced by the mandible, which opposes the construction bite, has considerable influence on the labial
direction of the lower incisors and the lingual direction of the upper incisors.
The following measurements were made in the sagittal section of the tomographic image: labial
alveolar bone thickness, lingual alveolar bone thickness, total alveolar bone thickness, total mandibular symphysis thickness, and total mandibular symphysis height on the labial
and lingual sides of the lower incisors (Figure 1).
We mobilised the swelling from labial
region until deep ring.
