Assessment of the effect of the corticotomy-assisted orthodontic treatment on the maxillary periodontal tissue in patients with malocclusions with transverse maxillary deficiency: a case series

Abstract

BackgroundThe aim of the study was to assess the effect of corticotomy–assisted orthodontic treatment on soft tissue clinical parameters in patients with malocclusions with transverse maxillary deficiency.MethodsThe study included 20 generally healthy adult individuals with malocclusion, who underwent a corticotomy-assisted orthodontic treatment in maxilla. During the corticotomy performed after full-thickness flap elevation, only the buccal cortical plate was cut with the use of OTS-7, OTS7–4, OTS7-3 ultrasound tips of the piezosurgery device (Mectron s. p. a., Italy). A clinical examination was performed prior to the corticotomy procedure, then repeated – 3, 6, 9 and 12 months after the procedure. The following parameters were assessed: FMPI (full mouth plaque index), FMBOP (full mouth bleading on probing), PD (probing depth), CAL (clinical attachment level), GR (gingival recession height), RW (recession width), PH (papilla height), PW (papilla width), BS (bone sounding), biotype and KT.ResultsThere was a statistically significant reduction in PD (mean difference: 0.06; 95% Cl: − 0.33, − 0.18), CAL (mean difference: 0.07; 95% Cl: − 0.33, − 0.19), PH (mean difference: 0.26; 95% Cl: − 0.47, 0.05) and BS (mean difference: 0.13; 95% Cl: − 0.41, − 0.14) after the treatment. Statistically significant changes were also noted in relation to KT (mean difference: 0.17; 95% Cl: − 0.07, 0.27) and biotype (mean difference: 0.07; 95% Cl: 0.26, 0.39), which thickness increased significantly after the treatment. No statistically significant differences were observed in GR, RW and PW.ConclusionsThe corticotomy–assisted orthodontic treatment did not jeopardize the periodontal clinical status in maxilla. There is a need for further studies on a larger number of patient to compare the clinical findings with a control group as well as in patients with conventional orthodontic treatment in a longer follow-up time to find out more about the post-treatment periodontal tissue changes and stability.

Periodontal soft‐ and hard‐tissue changes after augmented corticotomy in Chinese adult patients with skeletal Angle Class III malocclusion: A non‐randomized controlled trial

“…[10][11][12][13] Investigators have noted increases in the buccal bone thickness (BT) of 0.19 to 1.56 mm after combined treatment, [14][15][16] and increases in the width of the buccal keratinized gingiva (WKG) of 0.32 to 0.78 mm after multidisciplinary treatment. 17,18 However, evidence for the impact of augmented corticotomy on periodontal tissues, especially for the soft tissue, remains limited. Thus, the present non-randomized controlled trial was conducted to investigate changes in soft and hard periodontal tissues after augmented corticotomy in Chinese adult patients with skeletal Angle Class III malocclusion, with adjustment for potential confounders.…”

“…In recent years, the results of several preliminary studies have led researchers to propose the use of augmented corticotomy as a therapeutic approach to improve the limited periodontal soft and hard tissues of patients requiring orthodontic treatment 10‒13 . Investigators have noted increases in the buccal bone thickness (BT) of 0.19 to 1.56 mm after combined treatment, 14‒16 and increases in the width of the buccal keratinized gingiva (WKG) of 0.32 to 0.78 mm after multidisciplinary treatment 17,18 …”

Long-Term Assessment of Periodontal Tissues after Corticotomy-Assisted Orthodontic Arch Expansion

“…The sutures were removed 14 days post-op, and tooth brushing with a soft toothbrush and the roll technique was recommended. The detailed methodology and post-treatment results are presented in the publication from 2018 [ 25 ].…”

“…The currently available literature data do not provide a clear answer as to whether the use of corticotomy prior to orthodontic arch expansion prevents adverse bone and soft tissue changes [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. Moreover, there are no long-term data evaluating periodontal changes after this type of treatment.…”

A nomogram prediction of gingival recession in mandibular incisors of orthodontic-orthognathic treated skeletal class III malocclusion with or without PAOO: A retrospective cohort study

“…PAOO mainly causes improvements in soft and hard tissues in anterior teeth through periodontal tissue regeneration technology to avoid periodontal risks during the orthodontic treatment process. Recent research indicates that PAOO can effectively augment labio-alveolar bone thickness by an average of 0.19–1.56 mm following periodontal-orthodontic-orthognathic treatment [ [22] , [23] , [24] , [25] , [26] ] which can prevent GR after orthodontic treatment. A few studies have reported that the buccal KGW increases by about 0.32–1.28 mm 25-27 and GT by 0.19–0.43 mm after combined treatment [ 27 , 28 ].…”
