RESUMEN

INTRODUCTION: This study aimed to evaluate the efficiency of a newly constructed computer-based decision support system (DSS) on the basis of artificial intelligence technology and designed to plan treatment for patients with a deep overbite. METHODS: With the help of information technology, a DSS was developed specifically for treatment planning of deepbite malocclusion. The program inputs were the components and the contributing factors used commonly by the orthodontic clinicians in deepbite diagnosis. The program outputs were the treatment planning options for deepbite treatment. A total of 357 decisions made by the algorithm were evaluated for accuracy by comparing them to the actual treatment changes of 51 patients with a well-treated deepbite. RESULTS: The decisions made by the algorithm were precise, with 94.4% having a very good agreement with actual treatment changes determined using Cohen's kappa coefficient. CONCLUSIONS: The constructed DSS was shown to be an efficient tool for planning treatment of deep overbite malocclusion in the permanent dentition; thus, the artificial intelligence could be used to formulate a customized plan for orthodontic clinicians.

RESUMEN

BACKGROUND: The aim of this study was to determine the retention practices following orthodontic treatment in a tertiary health institution in Nigeria. METHODS: A retrospective study conducted in the Orthodontic Clinic of the Lagos University Teaching Hospital over a 3-year-period. Data on the type of retainers used and the retention practices in the upper and lower arches were obtained from case files of patients who had completed orthodontic treatment in the institution. Statistical analysis was performed using IBM SPSS software version 23. RESULTS: The demographic variables comprised of 136 subjects; 93 females (68.4%) and 43 males (31.6%). Their ages ranged from 9-44 years with a mean age of 18.96 ± 6.75. Class I malocclusion was the most common malocclusion pattern (84.6%), followed by Class II (10.3%) and Class III (5.1%). Removable retainers were more commonly used and accounted for retention carried out in 85.3% of the study population. There was a preference for the use of removable retainers in the upper arch; the Hawley retainer being the most used (79.4%). In the lower arch however, no form of retention was carried out for majority of the patients after orthodontic treatment (86.8%). However, when done, the fixed lingual retainer was the most frequently used (13.2%). CONCLUSION: The Hawley retainer was the predominant retainer in this study. The fixed lingual retainer was the most frequently used in the lower arch. Longitudinal studies are required to determine efficacy of different types of retention following orthodontic treatment.

RESUMEN

Patients whose with facial appearance involves dental anomalies and malocclusion face an increased prevalence of various psychosocial problems such as a high level of social anxiety, social avoidance, and low quality of life. This study investigates the patients with craniofacial anomalies and their psychological adjustment concerning the facial and dental appearance. It also evaluates the expectations of this patient group from the orthodontic treatment. Two steps were done in this study. In the first step, translation and validation of the Derriford Appearance Scale (DAS59), The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), and Patient Expectation from the Orthodontic Treatment (PEOTQ) questionnaires into Maithili were done, and then the main study was conducted using these valid questionnaires. This was a cross-sectional study conducted on the patients with congenital craniofacial anomalies visiting the orthodontics department of Patna Dental College and Hospital, Patna (Bihar). All the patients received the Maithili DAS, Maithili PIDAQ and Patients' Expectation from the orthodontic treatment questionnaires. The Maithili version of DAS59, PIDAQ and PEOTQ were developed with outstanding reliability and validity. A significant difference between PIDAQ (p<0.001) and DAS59 scores (p<0.001) was found. In females, the total PIDAQ score was significantly higher as compared to males, but there was no association of DAS scores with gender. Place of residence showed no association with PIDAQ and DAS59 scores in patients. Patients and controls had significant differences between various items, and a comparison was made in terms of expectation from the orthodontic treatment. Altered facial and dental appearance in patients with craniofacial anomalies showed a significant psychological impact.

RESUMEN

INTRODUCTION: The effects of Invisalign clear aligner treatment with and without Dental Monitoring (DM) were compared for treatment duration, number of appointments, refinements and refinement aligners, and accuracy of Invisalign in achieving predicted tooth positions (aligner tracking). The null hypothesis was that there are no differences between Invisalign with and without DM in these parameters. METHODS: A sample of 90 consecutively treated Invisalign patients (45 control, 45 DM) fitted the inclusion and exclusion criteria. Treatment duration, number of refinements, number of refinement aligners, time to first refinement, number of appointments, number of emergency visits, and accuracy of predicted tooth movement were observed for differences. RESULTS: The 2 groups were homogeneous (P >0.05) for sample size, age, gender, Angle classification, maxillary and mandibular irregularity index, and the number of initial aligners. There was a significant (P = 0.001) reduction in the number of appointments by 3.5 visits (33.1%) in the DM group. There was also a significant (P = 0.001) reduction in the time to the first refinement (1.7 months) in the DM group. Compared with Invisalign predicted tooth positions, actual tooth positions were statistically (P <0.05) more accurate for the DM group for the maxillary anterior dentition in rotational movements and mandibular anterior dentition for buccal-lingual linear movement. Invisalign therapy without DM was closer to predicted tooth positions for the maxillary posterior dentition for the tip. None of these differences surpassed the clinically significant thresholds (>0.5 mm or >2°); however, the DM group achieved this in 1.7 fewer months. CONCLUSIONS: DM with Invisalign therapy resulted in a reduced number of appointments by 3.5 visits (33.1%). The DM group also achieved a clinically similar accuracy in obtaining predicted tooth movements compared with the control group in 1.7 fewer months, indicating improved aligner tracking in the DM group.

RESUMEN

INTRODUCTION: Rapid palatal expansion is a common therapy during orthodontic treatment and could be a preliminary step for correcting different malocclusions; furthermore, this treatment could be necessary at any age. Different anchorage approaches have been proposed to obtain an effective skeletal result, although every device produces both dental and skeletal effects. This study aimed to compare the dentoskeletal effects of a bone-borne palatal expander considering 2 groups of patients of different ages. METHODS: Twenty-four patients consecutively treated were included in the study; patients were divided into 2 groups according to their age: group 1 with age ≤16 years and group 2 patients >16 years. All patients had a preexpansion cone-beam computed tomography scan; a second scan was required at the end of activations. All patients received a bone-borne appliance anchored on 4 miniscrews. RESULTS: Significant intragroup differences were found for maxillary width and dental diameters. No significant differences were found between groups with regard to longitudinal changes, except for the maxillary right plane. CONCLUSIONS: The use of bone-borne maxillary expansion was effective in generating palatal widening both in growing and young adult patients. No significant skeletal or dental differences were found between groups.

RESUMEN

BACKGROUND: The purpose of this study was to analyze the relationship between body posture and sagittal dental overjet in children before and after early orthodontic treatment with removable functional orthodontic appliances. METHODS: Angle Class II patients (mean age 8.2 ± 1.2 years; 29 males and 25 females) with a distinctly enlarged overjet (> 9 mm) were retrospectively examined regarding body posture parameters before and after early orthodontic treatment. In addition, changes in overjet were investigated with the aid of plaster models. Forms of transverse dysgnathism (crossbite, lateral malocclusions) and open bite cases were excluded. Body posture parameters kyphosis, lordosis, surface rotation, pelvic tilt, pelvic torsion and trunk imbalance were analyzed by means of rasterstereographical photogrammetry to determine, if the orthodontic overjet correction is associated with specific changes in posture patterns. RESULTS: In nearly all patients an overjet correction and an improvement regarding all body posture and back parameters could be noted after early orthodontic treatment. Overjet reduction (- 3.9 mm ± 2.1 mm) and pelvic torsion (- 1.28° ± 0,44°) were significantly (p < 0.05) and moderately correlated (R = 0.338) with no significant associations found for the other posture and back parameters (p > 0.05). CONCLUSION: Overjet reduction during early orthodontic treatment may be associated with a detectable effect on pelvic torsion.

RESUMEN

OBJECTIVES: To investigate the skeletal and dentoalveolar effects of Invisalign's G5 protocol with virtual bite ramps in the treatment of adults with skeletal deep bites. MATERIALS AND METHODS: This retrospective study was conducted on consecutively treated adults presenting with skeletal deep bites as defined by the Overbite Depth Indicator (ODI). Subjects were divided into 2 groups: Invisalign group (n = 24) treated with the Invisalign G5 protocol and a full fixed appliance (FFA) group (n = 24) treated with edgewise FFAs and matched to the Invisalign group by ODI, sex, type of malocclusion, and non-extraction treatment. Pretreatment (T1) and post-comprehensive treatment (T2) lateral cephalograms were obtained and analyzed. RESULTS: Both the Invisalign and FFA groups showed significant changes from T1 to T2 in ODI and other skeletal and dentoalveolar measurements. The mean change in ODI was -1.5° (P < .001) for the Invisalign group and -2.0° (P < .001) for the FFA group. The mean decrease in overbite was 1.3 mm (P < .001) and 2.0 mm (P < .001) for the Invisalign and FFA groups, respectively. The mean increase in mandibular plane angle (Sn-GoGn) was 0.65° (P = .003) for the Invisalign group and 1.15° (P < .001) for the FFA group. When the groups were compared with each other, both ODI (P = .03) and overbite (P = .003) were significantly different in addition to other measurements. CONCLUSIONS: Although FFA treatment had more apparent skeletal changes for deep bite adult patients when compared with Invisalign, both systems were effective in opening deep bites at dentoalveolar and skeletal levels.

RESUMEN

INTRODUCTION: The study investigated which patient and orthodontic treatment factors act as predictors for the conclusion of the ongoing treatment in a dental clinic of a specialization program in Orthodontics. METHODS: Data were collected from the records of patients treated from 1997 to 2015. Potential predictors for treatment conclusion were investigated: patient-related factors (PRFs) and treatment-related factors (TRFs). PRFs were sex, age, face balance, Angle malocclusion classification, open bite, denture, facial pattern, facial profile, buccal corridor, crossbite, maxillary deficiency, and sagittal mandibular behavior; and TRFs were therapeutic approaches, treatment modality, extractions, and Bolton discrepancy. The initial and final treatment dates were collected. Descriptive data analysis, univariate, and multivariate logistic regression were performed (5% significance). RESULTS: Of the 903 records, 561 patients were included in the study. It was demonstrated that starting the treatment at a young age (PRF) and the presence of crossbite (TRF) are predictive factors for the treatment conclusion. A vertical facial pattern (dolichofacial or brachyfacial) and a greater number of extractions for orthodontic reasons may contribute positively to the conclusion of the treatment. The frequency of treatment inconclusion was higher during the first 2 years of treatment (more than 50% of the patients that initiated the treatment). CONCLUSIONS: Young age at the beginning of treatment and the presence of crossbite malocclusion can increase the chance of treatment conclusion.

RESUMEN

OBJECTIVE: To investigate the value-addition of obtaining lateral cephalometric radiographs during the treatment planning phase of orthodontic treatment. MATERIALS AND METHODS: The records of 100 orthodontic patients were presented to seven scorers during two phases that were 6 weeks apart. In the first phase, scorers completed a seven-question survey with questions regarding treatment planning. They were given various diagnostic records that did not include a lateral cephalometric radiograph. Six weeks later, the same scorers completed the same survey for the same patient cases with the same diagnostic records that additionally included a lateral cephalometric radiograph. Correlation coefficients were used to calculate intrarater agreement and inter-rater agreement within the study. RESULTS: Cohen's kappa values showed moderate to almost perfect agreement for the majority of survey questions. Intrarater agreement ranged between 0.430 and 1. Cronbach's alpha reliability statistics showed good interrater agreement for all questions in the survey. Agreement ranged from 0.710 to 0.913 across the survey questions. Diagnosing Angle classification of occlusion had the highest level of agreement and differentiating between skeletal and dental malocclusion had the lowest level of agreement. CONCLUSIONS: The lateral cephalometric radiograph is not a necessary diagnostic tool for most cases in orthodontic diagnosis and treatment planning. Weighing the usefulness of a lateral cephalometric on a case-by-case basis should be recommended to align with the principle of ALARA (as low as reasonably achievable), especially in a primarily pediatric population.

RESUMEN

OBJECTIVE: To assess the efficacy and efficiency of treatment in adolescents presenting with mild malocclusions, comparing outcomes using clear aligners to fixed appliances. MATERIALS AND METHODS: Patients identified retrospectively and consecutively from one private practice had been treated with either clear aligners (Invisalign, Align Technology, Santa Clara, Calif) or fixed appliances (0.022 Damon, Ormco, Orange, Calif; n = 26/group). Assessments of occlusion were made using the American Board of Orthodontics Discrepancy Index (DI) for initial records and Cast-Radiograph Evaluation (CRE) for final records. Number of appointments, number of emergency visits, and overall treatment time were determined from chart reviews. Data were analyzed using Pearson's correlation, Wilcoxon rank tests, unpaired t-tests, and Chi-square tests, with significance set to P ≤ .05. RESULTS: Pretreatment, the aligner and fixed groups showed no significant difference in overall severity (DI: 11.9 ± 5.3 vs 11.6 ± 4.8) or in any individual DI category. Posttreatment scores showed finishes for the aligner group had fewer discrepancies from ideal relative to the fixed appliance group (CRE: 30.1 ± 8.3 vs 37.0 ± 9.3; P < .01). Patients treated with aligners had fewer appointments (13.7 ± 4.4 vs 19.3 ± 3.6; P < .0001), fewer emergency visits (0.8 ± 1.0 vs 3.6 ± 2.5; P < .0001), and shorter overall treatment time (16.9 ± 5.7 vs 23.4 ± 4.4 months; P < .0001). CONCLUSIONS: Outcomes for treatment of mild malocclusions in adolescents showed equivalent effectiveness of clear aligners compared to fixed appliances, with significantly improved results for clear aligner treatment in terms of tooth alignment, occlusal relations, and overjet. Assessment of the number of appointments, number of emergency visits, and overall treatment time showed better outcomes for treatment with clear aligners.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate changes in the mandibular dental arch and incisor alignment induced by combined bonded Rapid Maxillary Expansion (RME) and Face Mask (FM) therapy in the mixed dentition stage in which leeway space was used throughout the treatment. STUDY DESIGN: This retrospective study evaluates pretreatment (T0) and posttreatment (T1) cephalometric radiographs and orthodontic models of 25 patients (mean age: 10.75±2.64), in mixed dentition, having skeletal Class 3 anomaly (ANB<0) with maxillary retrognatism (SNA=77.2±0.68) and bilateral posterior crossbite treated with bonded Hyrax RME-FM. Mean treatment duration was 10.4 months. Dental model measurements were performed using the 3Shape OrthoAnalyzerTM 2013-1 program. Changes in the mandibular incisor and first molar positions were determined on cephalometric radiographs. Statistical evaluation was done with a paired t-test. RESULTS: A significant increase of 1.2 mm was found in intermolar width (p<0.001) in the mandibular dental arch. There was a significant decrease (1.4 mm) (p<0.001) in arch depth and an increase in arch length discrepancy (1.7mm)(p<0.01). There was a significant increase (0.8mm) (p<0.05) in the incisors' irregularity score (LII). IMPA showed a significant decrease (p<0.05). CONCLUSION: Clinicians should be aware that mandibular crowding tends to increase during this type of combined therapy.

RESUMEN

BACKGROUND: Although several researchers have analyzed the dental identity of patients experience with corrective methods using fixed and removable appliances, the consequences stay debatable. This meta-analysis intended to verify whether the periodontal status of removable appliances is similar to that of the conventional fixed appliances. METHODS: Relevant literature was retrieved from the database of Cochrane library, PubMed, EMBASE, and CNKI until December 2019, without time or language restrictions. Comparative clinical studies assessing periodontal conditions between removable appliances and fixed appliances were included for analysis. The data was analyzed using the Stata 12.0 software. RESULTS: A total of 13 articles involving 598 subjects were selected for this meta-analysis. We found that the plaque index (PLI) identity of the removable appliances group was significantly lower compared to the fixed appliances group at 3 months (OR = -0.57, 95% CI: -0.98 to -0.16, P = .006) and 6 months (OR = -1.10, 95% CI: -1.60 to -0.61, P = .000). The gingival index (GI) of the removable appliances group was lower at 6 months (OR = -1.14, 95% CI: -1.95 to -0.34, P = .005), but the difference was not statistically significant at 3 months (OR = -0.20, 95% CI: -0.50 to 0.10, P = .185) when compared with that of the fixed appliances group. The sulcus probing depth (SPD) of the removable appliances group was lower compared to the fixed appliances group at 3 months (OR = -0.26, 95% CI: -0.52 to -0.01, P = .047) and 6 months (OR = -0.42, 95% CI: -0.83 to -0.01, P = .045). The shape of the funnel plot was symmetrical, indicating no obvious publication bias in the Begg test (P = .174); the Egger test also indicated no obvious publication bias (P = .1). CONCLUSION: Our meta-analysis demonstrated that malocclusion patients treated with the removable appliances demonstrated a better periodontal status as compared with those treated with fixed orthodontic appliances. However, the analyses of more numbers of clinical trials are warranted to confirm this conclusion.

RESUMEN

INTRODUCTION: This article evaluates and reports on the satisfaction of adult patients across the United States who received orthodontic treatment for anterior open bite malocclusion. The factors that influence satisfaction are also described. METHODS: Practitioners were recruited from the National Dental Practice-Based Research Network. On joining the Network, practitioner demographics and information on their practices were acquired. Practitioners enrolled their adult patients in active treatment for anterior open bite. Patient demographics, patient dentofacial characteristics, and details regarding previous and current treatment were collected through questionnaires at enrollment (T1). Pretreatment lateral cephalograms and intraoral frontal photographs were submitted. Treatment performed, and details related to treatment outcome were recorded through questionnaires at the end of active treatment (T2). Posttreatment lateral cephalograms and intraoral frontal photographs were submitted. Patient satisfaction at T2 was assessed using a 5-point Likert-type scale and open-ended responses. Predictive univariate models were developed to evaluate the factors that affect patient satisfaction. Open-ended responses were reviewed for general trends. RESULTS: T2 data were received for 260 patients, and 248 of these patients completed and returned the patient satisfaction questionnaires. High levels of satisfaction were found in this sample of adult patients receiving treatment for anterior open bite malocclusion. Specifically, 96% of the sample reported being very or somewhat satisfied. Only 10 patients (4%) were not satisfied with the treatment provided or an element of the final result. Successful open bite closure, treatment modality, and certain patient characteristics may affect patient satisfaction. However, there was insufficient power to demonstrate statistical significance because of the very low number of dissatisfied patients. Open-ended responses directly associated with patient satisfaction were received from 23 patients (9%). They relayed positive, neutral, and negative feelings about the treatment received and final results. Additional responses regarding the orthodontic treatment in general, but not specifically linked to patient satisfaction, were received from 119 patients (48%). These comments depict an overwhelmingly positive experience. CONCLUSIONS: Adult patients who received orthodontic treatment for anterior open bite malocclusion were generally satisfied with the treatment provided, as well as the final esthetic and functional results.

RESUMEN

BACKGROUND: The Multiloop Edgewise Archwire (MEAW) appliance is an orthodontic treatment method suitable for the therapy of severe types of malocclusions such as open bites or anterior crossbites. The cephalometric Denture Frame Analysis (DFA) provides a supportive diagnostic tool for patient-specific treatment planning concerning the rearrangement of occlusion within the "denture frame". The objective of this study is to give a comprehensive overview of the national and international scientific literature about MEAW and DFA regarding the general therapeutic effects, advantages and limitations. METHODS AND MATERIALS: A computerized literature search was performed using four principal medical databases (PubMed/Medline, Google Scholar, Web of Science and Cochrane Central Register of Controlled Trials) and supplemented by manual searching of the references listed in the retrieved articles. The results were screened and assessed following the PRISMA guidelines. RESULTS: Six hundred seventy-seven full articles were assessed for eligibility. A number of 134 articles went through qualitative analysis and 3 studies were finally involved in comparative synopsis. The findings reveal advantageous characteristics of the MEAW technique such as a high degree of three-dimensional individual tooth control and a comparatively low load deflection rate, causing mostly dentoalveolar changes without significantly influencing the skeletal structures. CONCLUSION: Based on current literature, the MEAW technique appears to have several therapeutic benefits and serves as a sufficient alternative treatment method for dentoalveolar compensation, when measures of orthognathic surgery are rejected. Concerning the deficient data basis of available literature and the low level of scientific evidence, further studies are required in order to expand on the knowledge in this subject area. Several aspects like the effectiveness or the long-term stability have to be evaluated more extensively. Moreover, the transferability of the DFA to ethnic groups other than the Asian ethnicity should be examined further.

RESUMEN

INTRODUCTION: Supervising the development of occlusion, managing problems during the transition from mixed to permanent dentition, as well as controlling environmental factors that contribute to establishing malocclusion, are important actions to achieve a Class I occlusion with facial balance. Among these problems, the malocclusions associated with dysfunctions such as mouth breathing or obstructive sleep apnea syndrome (OSAS), atypical swallowing and abnormal tongue position, open bites, crossbites and maxillomandibular discrepancies, and especially the Class III malocclusion can be listed. OBJECTIVE: The purpose of this article is to present and discuss the main aspects relevant to the benefits of performing the treatment of Class III malocclusion in patients with growth.

RESUMEN

The objective of this comparative retrospective cohort performed on 202 patients was to evaluate the influence of instrumental extraction (forceps, suction cup, spatula) during delivery on the need for orthodontic treatment. Questionnaires on the type of delivery were distributed in three different structures. The need for treatment was assessed using the IOTN indicator (Index of Orthodontic Treatment Need). The groups were compared by statistical tests at the significance level of 5 %. 202 patients were included (51 in the group « instrumental delivery ¼, 151 in the control group). With an average IOTN of 3.3 in the « instrumental delivery ¼ group versus 2.5 in the « non-instrumental delivery ¼ group, the difference between the two groups is statistically significant (p = 0.00015). Since the need for orthodontic treatment is significantly higher in patients born by instrumental delivery compared to patients born without instrumental support, instrumental extraction is therefore a risk factor in orthodontics, diagnosis and orthodontic treatment may be indicated in these patients. In addition, provided that it is proven effective, early osteopathic management may be recommended.

RESUMEN

This study is aimed at evaluating the Oral Health Related Quality of Life (OHRQoL) in adolescents aged 11-14 years-old during orthodontic therapy and 18 months after the start of treatment and the possible role of psychological parameters. Sixty patients were recruited, and data were collected using self-administrated questionnaires and intraoral clinical examinations. The questionnaires included sociodemographic characteristics (age, gender), the Lebanese version of the Child Perception Questionnaire between 11 and 14 years CPQ11-14 to assess the OHRQoL, the Discrepancy Aesthetic Index (DAI) for malocclusion, and the Child Health Questionnaire « CHQ-CF87 ¼ to appraise Self-Esteem (SE) and Psychological Well-Being (PWB). The mean scores of CPQ11-14 and its four subdomains were significantly better for participants with high SE /PWB compared to those with low SE / PWB at baseline. These same scores improved significantly during orthodontic treatment (p < 0.001). However, DAI was significantly better in patients with low self-esteem and psychological well-being. Our findings showed improvement in oral health perception and psychologic parameters during orthodontic treatment. Investigators should consider the need to control the psychological parameters of patients when assessing orthodontic treatment need and improvement in OHRQoL during orthodontic treatment.

RESUMEN

Since 1907, the international community has used Angle's classification to assess the mesio-distal relationships of the dental arches. It is the basis of the diagnosis of malocclusion in the sagittal dimension and indicates or not an orthodontic correction treatment. This work was aimed to inventory the classification methods of malocclusions used today. Indices of treatment need were also presented because they are based on one or more occlusal anomalies to indicate treatment. The classifications were criticized and the contribution of a functional analysis based on the use of the trilogy setting, centering and guiding was detailed. The type of anomalies (skeletal and dental) must be completed by the analysis of the occlusal anomaly of setting (centering or guiding) and of the category of occlusion (functional occlusion, functional malocclusion or pathogenic malocclusion), ie its possible pathogenic impact on orofacial structures. A consensus on the classification of occlusal anomalies is necessary in order to better identify the anomalies and their global repercussions, and to better define the needs for orthodontic treatment.

RESUMEN

PURPOSE: The purpose of this study was to investigate the periodontal status in adult periodontal disease patients with malocclusion treated with digital clear aligners. METHODS: Thirty-three patients with periodontal disease who needed orthodontic treatment were selected. The patients were randomly divided into 2 groups, digital clear aligners group (experimental group, 16 patients) and fixed appliances group (control group, 17 patients). Bleeding index (BI), probing depth(PD), plaque index(PLI) and gingival index(GI) were recorded at baseline and 1, 3, 6 and 9 months during orthodontic treatment. SPSS 17.0 software package was used to analyze and compare the data of periodontal status between two groups. RESULTS: 1, 3, 6, and 9 months after orthodontic treatment, clinical parameters of the control group were significantly higher than baseline(P<0.05). The same measurements of the experimental group showed no significant differences at 1, 3, 6, and 9 months of treatment (P>0.05). After 1, 3, 6, and 9 months of treatment, the clinical parameters of BI, PLI and GI in the experimental group were significantly lower than the control group(P<0.05); PD in the experimental group was smaller than the control group, but there was no significant difference(P>0.05). CONCLUSIONS: Compared with conventional fixed appliance, clear aligner of digitalization can more effectively maintain periodontal heath in adult periodontal disease patients with malocclusion.
