Introduction. The Herbst device is widely used for correction of class II malocclusions; however, most of the researches carried out on the Herbst appliance in literature do not take into account patients with a different mandibular divergence. The aim of this study was to investigate the effects of Herbst on dental and skeletal structures and to evaluate possible influence of vertical facial growth patterns. Methods. A retrospective study was conducted on lateral cephalograms of 75 growing patients (mean age: 9.9 ± 1.9 years) with class II malocclusion treated with Herbst. Subjects were divided into 3 groups using the mandibular divergence index (SN and GoMe angle). Cephalometric parameters were evaluated using the modified SO (sagittal occlusion) Pancherz’s analysis. A statistical analysis was conducted to evaluate differences among groups using ANOVA. Results. Our study showed differences in response to treatment depending on patient’s facial vertical growth pattern. Cranial base angle and mandibular rotation were significantly different (p<0.05) between hypodivergent patients and normodivergent patients and between hypodivergent and hyperdivergent subjects. Conclusion. Hypodivergent patients increased their mandibular divergence during treatment to a greater extent than normodivergents; moreover, hyperdivergent patients exhibited a decreased mandibular divergence at the end of the treatment.

In this case report, Authors describe the correction of a class II malocclusion using only an Herbst appliance palatally anchored with miniscrews. Before sagittal correction in the same appliance we applied a palatal screw to obtain maxillary expansion. The device were removed after 12 months of treatment. The final result included the correction of Class II malocclusion by lower dentoalveolar compensation mainly. The lip function favorite the spontaneous correction of upper frontal torque with consequent improvement of facial esthetics. After a follow up of 12 months the clinical result is satisfactory in terms of occlusion and esthetics. This clinical case showed a simple orthopedic and dentoalveolar approach to correct transversal discrepancy, dental class II malocclusion and also frontal proclination only with one appliance in a very short treatment time.

Summary Background The effects of mandibular propulsion appliances in adults have some controversial results. While some authors claim that its use in non-growing patients could produce some dentoskeletal effects, other studies indicate that Class II correction occurs only through significant dental effects. Objective To evaluate the effects in non-growing Class II patients with mandibular retrusion, promoted by the treatment with mandibular propulsion appliances and determine if they produce mandibular changes. Methods The research was carried out in nine electronic databases and additional manual searches up to July 2019. Selection criteria were no restriction was placed on date and publication language. Randomized or non-randomized clinical trials with/without control were included. They must evaluated non-growing patients with Class II malocclusion, treated with mandibular propulsion appliances; outcomes were assessed before and after treatment. Data collection and analysis Data were extracted by two independent examiners in duplicate. The ROBINS-I tool was used to assess the methodological quality of the included studies. Results Of the 2824 articles identified, 11 non-randomized clinical articles were selected for qualitative analysis and 8 for quantitative analysis. SNB (0.87°, CI 95% 0.08, 1.66), ANB (−0.82°, CI 95% −1.24 to 0.40) and Pg/OLp [2.3 to 1.2 mm (P &lt; 0.001)] presented smallest but significant mandibular changes with some differences regarding the used appliance. The Herbst appliance showed the largest mandibular changes followed by the SUS appliance when evaluated through Ar-Pg. SNA showed non-significant changes. Overbite (−2.85. CI 95% −3.06, −2.64), Overjet (−5.00.CI 95% −5.45, −4.55) showed significant changes in all devices. Class II correction occurs through a significant labial movement of the mandibular incisors, some lingual inclination of the maxillary incisors and minor skeletal changes. Conclusions All mandibular propulsion appliances examined, showed efficiency in normalizing the Class II malocclusion in adult patients; however, changes were acquired mainly through dentoalveolar changes. Some minor mandibular forward changes was noted, mainly in patients treated with the Herbst appliance. Randomized clinical trials are needed to improve scientific evidence. Registration PROSPERO (code CRD42017067384).

Abstract Objective: To evaluate the relative skeletal and dental changes produced by the crown- or banded-type Herbst appliance in growing Class II division 1 malocclusion cases. Materials and Methods: Several electronic databases were searched with the help of a health sciences librarian, without language limitation. Abstracts that appeared to fulfill the initial selection criteria (Herbst use and clinical trial) were selected by consensus, and their original articles were then retrieved. Clinical trials were selected that used lateral cephalograms to assess immediate skeletal and dental changes from the use of either crown or banded Herbst appliances. Clinical trials that employed other simultaneous potentially growth-modifying appliances or surgery were excluded. A comparable untreated Class II division 1 malocclusion control group was required to factor out normal growth changes. References from the selected articles were also hand searched. Results: Only three articles meet the selection criteria. Proclination and anterior movement of the lower incisors, overjet reduction, and improvement of first molar relationship thorough mesial movement of the first molars, reduction of ANB angle, and an increase in the mandibular plane angle were reported. There were mixed findings as to mandibular sagittal length and position and increases in lower face height, both anteriorly and posteriorly. No statistically significant changes were noted in the sagittal length or position of the skeletal maxilla. Conclusions: Dental changes have more impact than skeletal changes in the correction of Class II division 1 malocclusions with the crown or banded Herbst appliance.

ABSTRACT Objectives: To compare the prevalence of clinical complications between two different telescopic Herbst systems: the conventional telescopic system, with traditional rod and tube (RMS), and the Manni telescopic Herbst appliance (MTH). Materials and Methods: Ninety subjects treated with RMS were compared to 89 patients treated with MTH. All of the complications that occurred were reported, and percentages of prevalence were calculated. Results: MTH showed a significantly lower percentage of reversible complications (that did not require appliance removal) when compared to the reversible complications during RMS treatment (20.2% vs 51.1%). No statistically significant differences were found between RMS and MTH regarding irreversible complications (that required appliance removal and full re-make). All of the irreversible complications occurred after reversible complications in the RMS group, while most of the irreversible complications in the MTH group occurred without any previous reversible complication. Conclusions: MTH exhibited a smaller number of clinical complications during Class II skeletal malocclusion therapy.
