The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

OBJECTIVE: To observe the clinical effect difference between warm acupuncture at Zusanli (ST 36) and Guanyuan (CV 4) combined with ginger moxibustion at points and western medication for premature ovarian failure (POF). METHODS: Fifty patients with POF were randomly assigned into an acupuncture-moxibustion group and a western medication group, 25 cases in each group. Warm acupuncture (30 min a time) at Zusanli (ST 36) and Guanyuan (CV 4) combined with ginger moxibustion (1.5 h a time) at points were used in the acupuncture-moxibustion group, once a day, 5 times a week. Three courses were given, one month as a course. Climen tablet was prescribed orally from the 5th day of menstruation in the western medication group, one tablet a time, once a day. The medication was given for 3 months, 7 days between the two 21-day medication. Before and after treatment, electrochemiluminescence was used to measure follicle stimulating hormone (FSH) and luteinizing hormone (LH); euzymelinked immunosorbent assay was applied to test estradiol (E); transvaginal color doppler sonography and abdomen ultrasound were applied to determine peak systolic velocity (PSV) of ovarian blood flow, resistance index (RI), pulsatility index (PI), ovarian volume and the number of sinus follicles (AFC). The clinical effect was compared between the two groups. RESULTS: After treatment, FSH and FSH/LH were lower than those before treatment in the two groups (all <0.05), and the value of FSH/LH in the acupuncture-moxibustion group as lower (<0.05). E, PSV and AFC after treatment were higher than those before treatment in the two groups (all <0.05), and PSV, AFC in the acupuncture-moxibustion group were higher (both <0.05). After treatment, RI and PI were lower and ovarian volume increased than those before treatment in the two groups (all <0.05). The total effective rate in the acupuncture-moxibustion group was 92.0% (23/25), and the total effective rate in the western medication group was 88.0% (22/25), without statistical difference between the two groups (>0.05). CONCLUSION Warm acupuncture at Zusanli (ST 36) and Guanyuan (CV 4) combined with ginger moxibustion at points are effective for POF patients, especially in improving FSH/LH, PSV and AFC.

Objective To analyze the effects of self-ligating bracket on enlarging the maxillary alveolar arch and to investigate the the non-extraction treatment programs.Methods All patients were used heat activated basic and precise theory for the orthodontist in order to make a plan fordeveloping nickel-titanium wire,then assessed by occlusalplane analysis method.The maxillary model andcephalometric radiographs were collected and measured before the treatment.The data of the resultswereanalyzed.Results After the treatment,the increase of the width of the dental arch was related to the /FMA,crowding degree and canines initial position.The increase of arch length was related to the ∠ANB,crowding degree,malocclusion classification,canines initial position andthe second molar eruption.Conclusion The essential factors include the crowding degree of arch,∠FMA,∠ANB,the angle of the anterior teeth,malocclusion classification,canines initial position andthe second molar eruptioncan affect the result of non-extraction quick self-ligating bracket appliance treatment on enlarging the maxillary alveolar.
