RESUMEN

BACKGROUND: To compare the efficacies of botulinum toxin-A injection and dry needling methods in the treatment of patients with myofascial pain syndrome (MPS) in the temporomandibular joint (TMJ). METHODS: In this prospective study, 40 MPS patients (29 women, 11 men) were randomly assigned to abobotulinum toxin-A injection (Group 1, n = 20) or dry needling (Group 2, n = 20) groups. Pain, crepitation, functional limitation, maximum mouth opening, jaw strength were evaluated at baseline and 6 weeks, and the results in both groups were compared. RESULTS: The average age of the authors' patients was 33.8±8.1. There was a remarkable difference between 2 groups regarding visual analog scale for TMJ pain at rest (P = 0.048). The pain at rest was relieved more effectively in Group 2 at the end of 6 weeks. Improvement in jaw protrusion angles on the right (P = 0.009) and left (P = 0.002) sides was more evident in Group 2 after 6 weeks. There were significant pain relief and functional improvement after treatment in both groups. In Group 2, recovery of the TMJ function was more obvious in 6 weeks following dry needling (P = 0.002). CONCLUSION: The authors suggest that abobotulinum toxin-A injection and dry needling yield satisfactory therapeutic outcomes regarding pain relief and restoration of function in patients with MPS involving TMJ. Further multicentric, randomized, controlled trials on larger series are warranted to obtain more accurate and reliable information.

RESUMEN

This case report introduces a treatment in mandibular prognathism correction by combining the surgery-first (SF) approach and clear aligners. An intraoral scanner (TRIOS 3, 3Shape, Copenhagen, Denmark) and a virtual setup program (OrthoAnalyzer, 3Shape) were used for treatment simulation. All clear aligners were fabricated using a 3-dimensional printer. The total treatment was completed within 3 months after surgery. An immediate improvement of the facial profile was obtained using the SF approach, and rapid and esthetic tooth movement was achieved using clear aligners. This case report demonstrated that the combination of the SF approach and clear aligners could be a patient-oriented surgical-orthodontic treatment method.

RESUMEN

An abnormal maxillomandibular ridge relationship frequently hinders oral implant treatment in patients with jaw deformities. Here, we describe a patient who was experiencing difficulty using dentures due to multiple maxillary tooth loss and mandibular prognathism. Treatment comprising sagittal splitting ramus osteotomy and alveolar ridge augmentation using bone grafts harvested from the mandibular ramus followed by implant treatment yielded good outcomes. The patient was a 47-year-old woman presenting with an unstable upper partial denture. Although prior prosthetic treatment for mandibular prognathism had resulted in normal overbite, she had since lost an increasing number of teeth due to advanced periodontal disease, impairing support for the denture. She was referred to the Department of Oral Implantology at the Tokyo Dental College Chiba Hospital in October 2008. Subsequent treatment comprised implant treatment following maxillary alveolar ridge augmentation and sagittal splitting ramus osteotomy to correct the maxillary-mandibular relationship. In January 2010, sagittal splitting ramus osteotomy and alveolar bone augmentation using a bone graft from the mandibular ramus were performed under general anesthesia. In July and August 2010, a total of 7 implants were placed in the maxilla and implant superstructure preparation started after 3 months. Taking both the patient's wishes and ease of maintenance into account, retrievable superstructures made of Auro Galvano Crown were fitted in April 2011. The jaw-to-jaw alveolar ridge relationship was improved by sagittal splitting ramus osteotomy, rendering subsequent treatment, from implant placement to superstructure preparation, feasible by conventional methods. The use of surplus bone generated during sagittal splitting ramus osteotomy for bone augmentation avoided the need to harvest bone from another area.

RESUMEN

Saethre-Chotzen syndrome (SCS) belongs to a group of rare congenital disorders connected with craniosynostosis and syndactyly. The purpose of this paper is to provide a review of the literature, to collect all reported symptoms and to describe the case of an 11-year-old female with SCS. The electronic databases PubMed and Scopus were searched to gain all symptoms of SCS described in the literature. The most common features of SCS described in the literature are synostosis of the coronal suture, syndactyly, facial asymmetry, low hairline, prominent ear crus, prominent nasal bridge, eyelid ptosis, and ocular hypertelorism. Less common symptoms include hearing loss, renal abnormalities and cardiac defects. Intraoral manifestations of SCS include maxillary hypoplasia, mandibular prognathism and high arched palate. Moreover, in some patients mental disability is observed, which may be connected with the size of the deletion in the Twist gene. There are no pathognomonic symptoms of SCS, which would indicate a diagnostic problem. Our patient displayed small dysmorphic changes within the skull and limbs and proper intellectual development. On the basis of an intraoral, extraoral examination and X-rays, she was diagnosed with relative mandibular prognathism. Currently, she is treated with a removable appliance. This report emphasizes a considerable variability of symptoms in SCS and highlights the most common features.

RESUMEN

Objective: The purpose of the present study was to investigate the improvements of facial profile and postoperative stability by single mandibular setback surgery. Materials and Methods: The study included twenty-seven patients who underwent mandibular prognathism correction by sagittal split ramus osteotomy (SSRO). Cephalometric radiograms (lateral and frontal) were collected and analyzed at three intervals: preoperatively (T1), immediately postoperatively (T2), and final follow-up postoperatively (T3). The lateral and frontal cephalometric parameters were measured. The immediate postoperative change (T21), postoperative stability (T32), and final surgical change (T31) were calculated and analyzed. The null hypothesis is that postoperative stability (T32) was not significantly correlated to amount of mandibular setback (T21). Results: The immediate postoperative change (T21) of menton (Me) was significantly backward 8.7 mm. In the final postoperative change (T31), average chin points anterior movements were approximately 0.32 mm. Investigating frontal appearance, inter ramus posterior (InterRp) and intergonion (InterGo) widths were significantly increased with 1.8 and 2.2 mm, respectively. Bilateral ramus angles were not significantly increased, about 1°. The horizontal Me (T32) had significant correlation (p = 0.028) with amount of setback (T21). Therefore, null hypothesis is rejected. Conclusion: Postoperative relapse was significantly correlated to the amount of setback. The frontal transverse changes (InterRp and InterGo) were significantly increased.

RESUMEN

This study investigated 36 patients at 10-15 years after they had undergone mandibular setback surgery by intraoral vertical ramus osteotomy (IVRO) and subsequent intermaxillary fixation for 6 weeks. The patients completed a 37-item structured questionnaire to evaluate patient satisfaction and possible long-term effects of the treatment. Visual analogue scales were used to measure self-perceived changes in seven items concerning oral function and appearance. Oral health-related quality of life was assessed using the Oral Impacts on Daily Performance (OIDP) index. The main reasons for seeking treatment were to improve chewing function and appearance. The treatment had resulted in significant improvements regarding chewing function, appearance, bullying, and self-confidence in social settings (all P<0.05). All patients were either very satisfied (61%) or reasonably satisfied (39%) with the treatment result. The mean OIDP frequency score was 8.49 on a scale from 8 to 40. Seventy-four percent of the patients reported no oral impacts on quality of life. In conclusion, 10-15 years after combined orthodontic and IVRO surgical treatment of mandibular prognathism, the patients were satisfied, and oral health-related quality of life was reported to be good.

RESUMEN

OBJECTIVES: To investigate the retromolar space available for molar distalization in patients with mandibular prognathism. MATERIALS AND METHODS: Using cone-beam computed tomography, the posterior mandibular dimensions in 110 consecutive patients with Class I or Class III malocclusion were measured (mean age, 27.0 ± 7.1 years). The shortest linear distances from the distal root of the right mandibular second molar to the inner border of the mandibular cortex were measured at the level of root furcation and 2, 4, and 6 mm apical to the furcation along the sagittal line and the posterior line of occlusion. The retromolar distances were compared between the Class I and Class III malocclusion groups using general linear mixed models. RESULTS: The retromolar space measured through the sagittal line showed no significant intergroup difference. Among the distances measured through the posterior line of occlusion, the space measured at depths 0 and 2 mm to the furcation were significantly greater in the Class III group than in the Class I group. CONCLUSIONS: Patients with Class III malocclusion have greater retromolar space for mandibular molar distalization along the posterior line of occlusion only at the level of the second molar furcation.

RESUMEN

Background: Although the headgear appliance has been used extensively to correct anteroposterior discrepancies, its treatment effects have not yet been adequately assessed in an evidence-based manner. Objective: Aim of this systematic review was to assess the therapeutic and adverse effects of early headgear treatment from controlled clinical trials on human patients in an evidence-based manner. Search methods: An unrestricted electronic search of six databases from inception to December 2015. Selection criteria: Randomized and prospective non-randomized controlled trials assessing the effects of headgear treatment on human patients. Data collection and analysis: After duplicate study selection, data extraction, and risk of bias assessment according to the Cochrane guidelines, random-effects meta-analyses of mean differences (MDs) and relative risks (RRs), including their 95% confidence intervals (CIs) were performed, followed by subgroup and sensitivity analyses. Results: A total of 18 unique studies with a total of 930 (56% male/44% female) patients were included. Headgear treatment was associated with a posterior translation of the anterior maxilla border in the short term, as seen by the mean annualized change in the SNA angle (MD = -1.63°/year; 95% CI = -2.20 to -1.06°/year; high quality evidence) compared to untreated patients. This effect was independent of the rotation of the palatal plane and the inclination of the upper incisors, while a proportional relationship with the initial discrepancy in SNA was seen. The clinical significance of this improvement diminished in the long term, although only limited evidence existed. Additionally, early headgear treatment might decrease the risk of dental trauma during the following years (RR = 0.34; 95% CI = 0.14 to 0.80; moderate quality evidence). Low quality evidence on the effect of headgear on the rotation of the palatal plane, the nasolabial angle, the occlusal outcome, and signs of temporomandibular disorders precluded robust assessments, due to risk of bias, inconsistency, imprecision, and small-study effects. Conclusions: Based on existing trials, headgear is a viable treatment option to modify sagittal growth of the maxilla in the short term in Class II patients with maxillary prognathism.

RESUMEN

PURPOSE: To examine and compare the 3-dimensional (3D) postoperative changes of the condylar position after mandibular setback surgery using the orthodontics-first approach (OFA) and surgery-first approach (SFA). MATERIALS AND METHODS: This retrospective cohort study included patients who had undergone bilateral sagittal split ramus osteotomy for mandibular prognathism using OFA or SFA. Computed tomography images were obtained and analyzed preoperatively (T0), postoperatively (T1), and at the 6-month follow-up visit (T2). The bodily shift of the condylar center and rotational movement of the condylar head were measured using the 3D coordinate system between each time point and compared between the OFA and SFA groups. Repeated measures analysis of variance with a Bonferroni post hoc test was used to compare the time course changes of the condylar position for the 2 surgical-orthodontic approaches. RESULTS: A total of 55 patients (mean age 21.9 years; 31 males, 24 females) were evaluated. Of the 55 patients, 29 had undergone OFA and 26, SFA. In both groups, the condyle showed perioperative lateral and inferior displacement with inward rotation, followed by returning to its preoperative position during the 6 months postoperatively. No significant difference was found between the 2 groups in the time course change of the condylar position. CONCLUSIONS: Regardless of the timing of the operation (OFA vs SFA), the perioperative and postoperative changes of the condylar position after mandibular setback surgery are equivalent.

RESUMEN

This case report presents the camouflage treatment that successfully improved the facial profile of a patient with a skeletal Class III malocclusion using bone-borne rapid maxillary expansion and mandibular anterior subapical osteotomy. The patient was an 18-year-old woman with chief complaints of crooked teeth and a protruded jaw. Camouflage treatment was chosen because she rejected orthognathic surgery under general anesthesia. A hybrid type of bone-borne rapid maxillary expander with palatal mini-implants was used to correct the transverse discrepancy, and a mandibular anterior subapical osteotomy was conducted to achieve proper overjet with normal incisal inclination and to improve her lip and chin profile. As a result, a Class I occlusion with a favorable inclination of the anterior teeth and a good esthetic profile was achieved with no adverse effects. Therefore, the hybrid type of bone-borne rapid maxillary expander and a mandibular anterior subapical osteotomy can be considered effective camouflage treatment of a skeletal Class III malocclusion, providing improved inclination of the dentition and lip profile.

RESUMEN

This case report describes the orthodontic camouflage treatment for a 16-year-old Chinese girl with a Class III malocclusion. The treatment included extractions of the mandibular second molars, fixed appliance therapy, and miniscrew-aided mandibular arch distalization. Pretreatment, posttreatment, and 2-year follow-up records are shown. The anterior negative overjet and the Class III molar and canine relationships were corrected. The patient's facial profile was greatly improved. The mandibular third molars erupted into the second molar spaces, with acceptable intercuspation with the maxillary dentition.

RESUMEN

Nonsurgical orthodontic treatment of a patient with severe skeletal Class III malocclusion, negative overjet, increased overbite and maxillary crowding is described Although the treatment options included an orthodontic-surgical approach, high cost of the surgical procedure was the main reason for extreme dental compensation to have been performed. Four-premolar extraction protocol associated with intermaxillary Class III elastics were used to correct the malocclusion at the expense of increasing the initial dental compensation without producing any noticeable skeletal change. Satisfactory and stable occlusion was achieved with dental and smile esthetics improvement, but the amount of facial changes was limited by the nonsurgical protocol. The clinical results and implications of compensatory treatment as well as its relevance within the patient context are discussed based on scientific evidences.

RESUMEN

The standards of dentistry are being elevated, with a greater emphasis being placed on esthetics along with functionality. Minimally invasive dentistry has become an essential component in creating restorations that are functional and have increased longevity. In the case discussed in this article, the patient underwent 9 months of orthodontic therapy to correct her improper overbite and overjet, and the spacing of her dentition so the teeth could be positioned for future minimally invasive restorations. Orthodontic therapy was paramount in positioning the teeth so that the future restorations would have ideal axial inclinations and be as minimally invasive as possible.

RESUMEN

Skeletal Anterior open bite abnormality in adults is probably the most difficult to correct in orthodontics just behind Skeletal Class III abnormality. Literature research shows various techniques to correct this problem, often via orthognathic surgery, but it was difficult to find in the literatures a simplified non-surgical technique. This author propose, a simplified, non-surgical technique to correct skeletal anterior open bite in adults using non-ligating, frictionless brackets and vertical elastics. Some indications and contra-indications will be discussed

RESUMEN

The objective of this article was to investigate the perception of esthetic changes in the facial profile of bilateral Class II patients treated with the Modified Thurow Appliance for extraoral treatment. Silhouettes were traced of profiles of patients who initially presented a bilateral Class II molar relationship and who, post-treatment, presented molars in a Class I relationship. Three groups were formed: the first composed of patients with maxillary protrusion (SNA >84°), the second with maxillary retrusion (SNA <80°), and the third with a well-positioned maxilla (SNA 80-84°). A panel of 200 lay evaluators judged the profile esthetics by a randomized drawing of the silhouettes. The multiple analysis results showed that the profile esthetic scores for the three positions of the maxilla were greatly influenced by significant interactions with the characteristics (like sex and age) of the evaluators: retrusive maxilla (Score *Age Group, p < 0.001), normal maxilla (Score *Sex, p = 0.024; Score *Age Group, p = 0.050) and protrusive maxilla (Score *Age Group, p < 0.001). It was observed that the profile of Class II patients with protrusion, normal relationship and retrusion of the maxilla, improved in their esthetic post-treatment result; however, the evaluators showed greater satisfaction with the groups of protrusion and normal position of the maxilla. The Modified Thurow Appliance provided significant improvements in the esthetics of the profile of patients who presented protrusion and normal position of the maxilla. However, its use was not the best treatment option for patients with maxillary retrusion.
