Effectiveness of Invisalign^® aligners in the treatment of severe gingival recession: A case report

Abstract

In this report, we demonstrate the effectiveness of the Invisalign ® system in the treatment of severe gingival recession and bone dehiscence through torque, translation, and intrusion movements in a young woman. Cone-beam computed tomography was used to assess bone parameters and check the teeth during treatment. The root of the mandibular right central incisor, which was buccally positioned and exhibited bone dehiscence of 9.4 mm, was moved toward the center of the alveolar process by using the Invisalign ® system and SmartForce ® features. The patient was monitored by a periodontist throughout the orthodontic treatment period. Her gingival recession reduced, while the bone dehiscence reduced from 9.40 mm to 3.14 mm. Thus, movement of the root into the alveolus promoted bone neoformation and treated the gingival recession. The findings from this case suggest that orthodontic treatment using the Invisalign ® system, along with periodontal monitoring, can aid in the treatment of gingival recession and alveolar defects.

Maxillary alveolar bone evaluation following dentoalveolar expansion with clear aligners in adults: A cone-beam computed tomography study

“… 14 , 30 , 32 , 33 In the present study, we used tomographic images acquired with a 0.25 mm voxel size, which is in accordance with the literature. 5 , 8 , 11 , 14 , 18 , 25 - 28 , 34 - 36 However, smaller voxel sizes would ideally be more appropriate for interpreting the obtained bone results with greater reliability.…”

Spontaneous Recession Repair after Orthodontic Treatment: Case Report with the Use of Digital Approach for Quantification of Soft Tissue Changes

“…Antanavičienė et al reported about improvement of 58.7% recession cases, while 36% of the analyzed recessions were stable, and 5.3% demonstrated progression after performed orthodontic interventions [ 1 ]. The case report of de Figueiredo et al demonstrated significant gingival recession and bone dehiscence reduction after the usage of clear aligner system, which helped to move the tooth root into the proper position within the alveolus [ 6 ]. Analogical positive recession repair outcomes were also reported during orthodontic treatment of anterior cross-bite [ 7 ] and Class II (division 1) malocclusion [ 8 ].…”

“…In the present case report, it was possible to provide prosthetic treatment without any orthodontic correction and change in patient's dentogingival appearance with the newly formed esthetic profile of crowns and bridges. Nevertheless, several previous studies demonstrated a positive effect of orthodontic correction on the gingival contour changes, while also on the optimization of occlusal relationship [5][6][7][8][9][10]. Considering available evidences, it was chosen to provide pre-prosthetic orthodontic treatment to improve complex treatment outcomes [5][6][7][8][9][10].…”

“…Meanwhile, anecdotic case reports available in the literature represent outcomes opposite to such mentioned above and are associated with the recessions' improvement after provided orthodontic treatment [5][6][7][8][9]. Some clinical cases also have shown spontaneous gingival recession closure after orthodontic treatment combined with some recessionoriented grafting procedures, but in presented reports, it was difficult to distinguish if the gingival margins improvements were caused by the periodontal surgery or foremost due to the orthodontic treatment itself [10].…”

Reference standard thickness for bone plates of upper teeth: an ultra-high-resolution study using tomographic mapping

“…However, the torque expression is still a challenge in the use of these appliances [15,46,47] and should also be considered as a part of the digital planning. The Invisalign ® system introduced the use of power ridges, which are pressure lines close to the gingival margin for increasing the contact pressure on the tooth surface, to control the movement of the tooth around its centre of resistance [16,48]. For the upper central and lateral incisors and canines, the results between dental inclination and palatal bone thickness were significantly negative in the middle and apical thirds, which reflects a reduction of bone tissue in these areas when inclination increases, and vice-versa.…”
