In these cases, the correction of class II can be hindered by molar distalization, obtained with ‘no-compliance therapy’ that involves the use of appliances which minimize the need for such co-operation and attempt to maximize the predictability of results. The aim of this review was to outline the effectiveness of no-compliance fixed orthodontic devices in the molar distalization. After selection according to the inclusion/exclusion criteria, 16 articles from 2000 to 2019 were qualified for the final analysis. The literature shows various no-compliance fixed devices whose effect is to distalize the maxillary molars. The present revision allows to conclude that there is a need to increase the number of studies, especially with regard to the most recently introduced devices in the literature. The analysed studies allow to hypothesize that these appliances act with a minimal variability of molar distalization and disto-inclination among them, although different effects among the appliances can be observed as regards to the anchorage.

Numerous countries shut-down various activities that were considered “not essential.” Dental treatment was in this category and, at the time of writing, only non-deferrable emergencies are still allowed in many countries. Therefore, follow-up visits of ongoing active therapies (e.g., orthodontic treatment) must be handled taking special precautions. This literature review aims at reducing in-office appointments by providing an overview of the technologies available and their reliability in the long-distance monitoring of patients, i.e., teledentistry.

  • 3D Lingual Treatment with Suresmile and Tads Case Report
    CASE STUDY Orthodontic technology case report: three- dimensional lingual treatment in combination with a temporary anchorage device (TAD) Dr. Edward Lin treats a case to resolve crowding, straighten teeth, and improve the smile istorically, the United States has Hlagged behind other countries in the world in regards to offering lingual orthodontics as an option for treatment to our patients. In my opinion, the reason for this discrepancy between the U.S. and other countries for lingual treatment is due to the two main challenges associated with lingual orthodontics: 1) difficult retie appointments for both patient and clinician, and 2) significantly longer appointments. However, I personally see this changing very quickly over the next several years for three main reasons: 1) esthetic orthodontic treatment is something that is highly desirable for our patients, 2) many patients are now aware of lingual treatment and are actively seeking it out, and 3) advances with technologies such as SureSmile® (OraMetrix), cone beam computed tomography (CBCT), and small lingual self- ligating brackets have made treatment with lingual orthodontics much easier for both Figure 1: Initial records 5/20/09 the clinician and the patient.

    ORIGINAL ARTICLE Dynamic smile visualization and quantification: Part 1. Evolution of the concept and dynamic records for smile capture David M. Sarver, DMD, MS,a and Marc B. Ackerman, DMDb Vestavia Hills, Ala, and Bryn Mawr, Pa The “art of the smile” lies in the clinician’s ability to recognize the positive elements of beauty in each patient and to create a strategy to enhance the attributes that fall outside the parameters of the prevailing esthetic concept. New technologies have enhanced our ability to see our patients more dynamically and facilitated the quantification and communication of newer concepts of function and appearance. In a 2-part article, we present a comprehensive methodology for recording, assessing, and planning treatment of the smile in 4 dimensions. In part 1, we discuss the evolution of smile analysis and review the dynamic records needed. In part 2, we will review smile analysis and treatment strategies and present a brief case report.
