RESUMO

BACKGROUND: Patient quality of life (QoL) during orthodontic treatment is an important consideration that requires greater academic investigation as greater focus is placed on enhancing patient experience. Quality of life (QoL) was assessed in three orthodontic appliance groups, i.e., vestibular, lingual, and aligners during the initial stages of treatment. The sample was comprised of 117 adult patient-subjects distributed into 3 groups: vestibular (n = 41), lingual (n = 37), and aligner (n = 39). A WHOQOL-BREF questionnaire surveyed four domains (physical health, psychological health, social relationships, and environment). RESULTS: Mean scores for domain 1, physical health, showed that the aligner group (28.1) had significantly greater scores than that of the vestibular (22.7) or lingual (22) groups. Domain 2, psychological health, demonstrated significant differences (P < 0.001) between all groups, with the aligner group scoring the highest (23.2), followed by the lingual (18.4) and vestibular (15.2) groups. Domain 3, social relationship, showed that aligner (10.9) and lingual (10.2) scores were significantly greater (P < 0.001) than those of the vestibular group (7.8). Domain 4, environment, displayed significant differences between all groups, with the aligner group scoring highest (32.1), followed by the lingual group (29.3), and lastly the vestibular group (26.4). Overall, the highest mean score was obtained by the aligner group (23.1) and the lowest mean score was by the vestibular group (18). The mean domain scores for all three groups were significantly different (P ≤ 0.005) from each other (Table 2). CONCLUSIONS: Overall, patients undergoing Aligner therapy reported the overall highest QoL scores, followed by lingual and vestibular groups.

RESUMO

OBJECTIVES: To compare the efficacy of orthodontic tooth movement with three aligner wear protocols: 7 day, 10 day, and 14 day. MATERIALS AND METHODS: Eighty patients were randomly allocated into three groups: group A (7-day changes), group B (10-day changes), and group C (14-day changes). The posttreatment scans were compared with the final virtual treatment simulations through digital superimposition. The differences between predicted and actual achieved treatment outcomes were computed in six angular and six linear dimensions. Differences >0.5 mm for linear measurements and >2° for angular measurements were considered clinically relevant. RESULTS: Within groups, and irrespective of wear protocol, all linear discrepancies in both jaws were deemed clinically insignificant (<0.5 mm) while nearly all angular discrepancies were considered clinically significant (>2.0°). When the three groups were compared, group C (14-day changes) showed significantly greater accuracy in the posterior segment for maxillary intrusion, distal-crown tip and buccal-crown torque, and mandibular intrusion and extrusion. The mean treatment duration in the 7-day aligner change group was nearly half that of the 14-day aligner change group (5 months vs 9 months). CONCLUSIONS: Fourteen-day changes were statistically significantly more accurate in some posterior movements. However, this difference in accuracy did not exceed the threshold for clinical significance (>0.5 mm/>2.0°). Achieving a clinically similar accuracy between the 7-day protocol and 14-day protocol in half the treatment time suggests a 7-day protocol as an acceptable treatment protocol. Clinicians may consider slowing down to a 14-day protocol if challenging posterior movements are desired.

RESUMO

Condylar resorption of temporomandibular joint findings in the panoramic radiographs is an indication of bone resorption suggesting possible degenerative joint disease that warrants early screen and subsequent referral to a dedicated specialist. This case series reports three patients that underwent the active orthodontic treatment for the duration of approximately 24-36 months. The patients were asymptomatic at the initial examination. The clinical examination was negative for clicking; the range of motion on opening, lateral excursion, and protrusion was normal. Neither of these patients had a history of rheumatic disease or bruxism. During the later stages of orthodontic treatment, two of the three patients reported mild pain and clicking during mastication, which was also confirmed chairside on clinical evaluation. Patients were referred to the orofacial pain specialist, were they were prescribed specific medication for the symptoms, along with cognitive behavioral therapy, and were further evaluated for splint therapy. Panoramic radiographs taken before the start of the treatment, during the treatment and at the completion of the orthodontic treatments indicate the progression in the resorption of mandibular condyle in all three patients suggesting possible degeneration that warrants further investigation and therapy.

RESUMO

The idea of a global orthodontic organization, the World Federation of Orthodontists (WFO), made up of national and regional orthodontic organizations, was realized in 1995 in San Francisco at the 4th International Orthodontic Congress that was held in conjunction with the 95th annual American Association of Orthodontists meeting. This umbrella organization strives to promote quality orthodontic care, practiced and delivered by orthodontic specialists in all parts of the world. In addition, it supports its member organizations with governing principles that promote appropriate membership criteria, qualified individual leadership participation, and long-term stability of the organization over time. In response to the Coronavirus Disease 2019 pandemic, the WFO has responded proactively and plans to augment its digital resources even further in the near future. This article describes the formation of the organization, the idea that germinated through the first three international orthodontic congresses, its workflow and membership criteria, the accountability and commitment it has toward its affiliates and individual members, and its plans for future years to come.

RESUMO

Mobile applications (apps) play an increasingly important role in day to day life. With the number of orthodontic-related apps continuing to increase, and the rapid development of artificial intelligence, the potential to yield tremendous benefits to both clinicians and patients is apparent. However, if orthodontic apps are to become mainstream and obtain greater acceptance, scientific validation and investigation of these apps are to be undertaken. This scoping review aimed to determine the scope and extent of the published literature on mobile apps in orthodontics, as well as identify the types of studies published, and summarize the outcomes studied- thus also giving direction for future research in a rapidly evolving subject area.

RESUMO

In the case report showcased, we describe orthodontic treatment of a female patient with an excessive gingival display on smiling and severe dental crowding, with maxillary canines positioned excessively buccal (ectopic) to and in near transposition to the lateral incisors. The treatment involved extractions and initial use of unmitigated forces leading to excessive gingival thinning and buccal root positioning of the ectopic canines. Eventually, the root position was corrected and periodontal equilibrium was attained. On finishing the treatment, all objectives were achieved with a good esthetic outcome as well as excellent dental and occlusal relationships.

RESUMO

This case reports the retreatment of a young adult who had a previous orthodontic history of inappropriate biomechanical strategies leading to iatrogenic effects with the formation of a dual occlusal plane causing anterior dental extrusion. As a result, an already severe dento-skeletal malocclusion with a vertical growth pattern, severe gummy smile, increased overjet and a very deep bite along with procumbent and incompetent lips became exaggerated. The high smile line and heavy convex profile were changed to an average smile line and a straight profile by intruding the anterior maxillary segment with anterior miniscrew anchorage and retracting the whole maxillary arch using IZC screws posteriorly. The treatment effect was similar to an anterior surgical impaction, thereby offering patients a viable alternative. Combining intrusion and gingivectomy produced an aesthetically pleasing smile and profile without the cost, morbidity, and potential complications of orthognathic surgery.

RESUMO

Objectives: The aim of study was to evaluate skeletodental and soft tissue treatment effects and the amount of maxillary molar distalization with modified C-palatal plates vs. Greenfield molar distalizer appliances in adolescents. Study design: The samples consisted of pre- and posttreatment lateral cephalograms collected from 39 patients with Class II malocclusion. The MCPP group was comprised of 21 patients (mean age: 11.7 ± 1.3 years) treated with MCPP appliances while the GMD group included 18 patients (mean age: 11.2 ± 0.9 years) treated with GMD. Fixed orthodontic treatment started with the distalization process in both groups. From each cephalograpm, twenty-nine variables were measured for analysis and then the two groups were compared. Descriptive statistics, a paired t-test, and multivariate analysis of variance were performed to compare the treatment effects within and between the groups. Results: There was significant treatmentrelated change in the sagittal position of the maxilla and the mandible within each group. However, there were no statistically significant inter-group differences. The mean maxillary first molar distalization was 3.96 mm in the MCPP group vs. 2.85 mm in the GMD group. Both groups showed minimal distal tipping, but the maxillary incisors were significantly extruded by 3.04 ± 0.89 mm (P < .001) in GMD group. There was no significant difference in treatment duration between the groups. Conclusions: The maxillary first molars of both the MCPP and GMD groups were effectively distalized and there were significant skeletal changes in the maxilla. However, the maxillary incisors were significantly extruded in the GMD group.

RESUMO

INTRODUCTION: The purpose of this research was to provide an update on the accuracy of tooth movement with Invisalign (Align Technology, Santa Clara, Calif). METHODS: This prospective clinical study included 38 patients treated with Invisalign Full or Invisalign Teen. All teeth, from the central incisor to the second molar, were measured on digital models created from intraoral scans. Predicted values were determined by superimposing the initial and final ClinCheck models, and achieved values were determined by superimposing the initial ClinCheck models and the digital models from the posttreatment scans. Individual teeth were superimposed with a best-fit analysis and measured using Compare software (version 8.1; GeoDigm, Falcon Heights, Minn). The types of tooth movements studied were a mesial-distal crown tip, buccal-lingual crown tip, extrusion, intrusion, and mesial-distal rotation. RESULTS: The mean accuracy of Invisalign for all tooth movements was 50%. The highest overall accuracy was achieved with a buccal-lingual crown tip (56%), whereas the lowest overall accuracy occurred with rotation (46%). The accuracies for mesial rotation of the mandibular first molar (28%), distal rotation of the maxillary canine (37%), and intrusion of the mandibular incisors (35%) were particularly low. CONCLUSIONS: There was a marked improvement in the overall accuracy; however, the strengths and weaknesses of tooth movement with Invisalign remained relatively the same.

RESUMO

BACKGROUND: The aims of the study were to compare the effects of Invisalign® with and without Dental Monitoring® (DM) GoLive® on the following parameters: treatment duration, number of appointments, number of refinements, total number of refinement aligners, and time to initial refinement. The patients' perspectives on Dental Monitoring® were also evaluated using an online questionnaire. A sample of 155 consecutively treated Invisalign® patients (67 control, 88 DM) fit the inclusion and exclusion criteria. RESULTS: The two groups were homogeneous (P > .05) for age, gender, angle classification, Little's Irregularity Index, and number of initial aligners. The DM group had significantly fewer office visits compared to the control (7.56 vs 9.82; P < .001). There were no significant differences between the DM and control groups respectively pertaining to treatment duration (14.58 vs 13.91), number of refinements (1.00 vs 0.79), number of refinement aligners (19.91 vs 19.85), and time to first refinement (9.46 vs 9.97). Questionnaire results showed that 68.8% (44 respondents) indicate that DM scans were "easy" or "very easy" to perform while 16 responders (25%) found it "difficult" or "very difficult." 71.9% (46 responders) were "satisfied or very satisfied" with the level of communication with the orthodontist using DM and 16% (10 responders) were "dissatisfied" or "very dissatisfied." The mean duration observed by patients to take a scan was 5.16 ± 3.6 min. Eighty-eight percent (56 responders) of patients prefer few office visits as possible, while 12% (8 responders) would actually prefer additional office visits. Overall, the mean satisfaction of patients with DM was 4.25 on the 5-point Likert scale. CONCLUSION: The DM group had a significantly reduced number of appointments (7.56) compared with the control group (9.82) (a reduction of 23%) over the treatment duration. There were no significant differences between the two groups in treatment duration, number of refinements, number of refinement aligners, or time to 1st refinement. Overall, DM was well received by patients. However, there was a small percentage (usually less than 15%) that was generally unsatisfied with DM in varying aspects and preferred more frequent, traditional office visits.

RESUMO

OBJECTIVES: To investigate factors associated with spontaneous mesialization of impacted third molars after second molar protraction to close the space caused by a missing mandibular first molar (L-6) or retained deciduous mandibular second molars with a missing succedaneous premolar (L-E). MATERIALS AND METHODS: Panoramic radiographs of patients treated with mandibular second molar protraction to close the space due to missing L-6 or L-E (14 males, 36 females, mean age = 18.6 ± 4.4 years) were analyzed before treatment (T1) and after second molar protraction (T2). Factors associated with the amount of third molar mesialization were investigated using regression analyses. RESULTS: Mandibular second molars were protracted by 5.1 ± 2.1 mm and 5.8 ± 2.7 mm, measured at the crown and root furcation, respectively. After second molar protraction, third molars showed spontaneous mesialization by 4.3 ± 1.6 mm and 3.8 ± 2.6 mm, measured at the crown and root furcation, respectively. Nolla's stage of the third molar at T1 (B = 0.20, P = .026) and second molar protraction time (B = 0.04, P = .042) were significantly associated with the amount of third molar mesialization. CONCLUSIONS: Greater third molar mesialization was observed when Nolla's stage of the third molar was higher before treatment and when the second molar protraction time was longer.

RESUMO

INTRODUCTION: Our objectives were to evaluate changes in the position of maxillary third molars with cone-beam computed tomography images in adolescents after total arch distalization using a modified C-palatal plate (MCPP) and to compare them with the changes in a matched control group. METHODS: We included 68 maxillary third molars of 40 adolescent patients (mean age, 12.6 years). They were divided into MCPP and control groups. Cone-beam computed tomography images were taken before and after molar distalization (mean duration, 14.4 months) in the MCPP group and also in the control group (mean duration, 12.9 months). The changes in the position, angulation, and rotation of the third molars were assessed, and the volumes of maxillary tuberosity were measured. RESULTS: After distalization, the third molars moved backward (1.2 mm) and upward (0.5 mm) in the MCPP group with a significant difference (P <0.003), and they moved downward and forward in the control group. The changes in rotation and angulation were insignificant. The volumes of maxillary tuberosity increased in both groups. CONCLUSIONS: Maxillary total arch distalization caused unerupted third molars to move backward and upward, with an insignificant difference in the posttreatment volume of maxillary tuberosity. Therefore, it may be possible to perform maxillary total arch distalization in adolescents with unerupted third molars without a germectomy, at least in the short term.
