This article presents a case of a Class II division 2 patient, with a short face and increased overbite, treated with second upper premolars extractions. For this treatment, multibracket fixed appliance with MBT .022 prescription was used. To control the anchorage during retraction, interradicular micro-screws were placed vestibular over first molars in first and second quadrant. Final results were satisfactory, achieving a bilateral molar class II and canine class I occlusion, correcting the overbite and overjet as well as obtaining a correct torque of the upper incisors. We also improve the facial aesthetics of the patient with a harmonized profile with the retrusion of the upper lip. Restoration of the anatomy of the upper lateral incisors was achieved with aesthetic composite restorations. [ABSTRACT FROM AUTHOR]

Since bracketing cemented directly into the enamel was introduced into orthodontic practice, the problem has always existed to determine and achieve the exact and precise place to determine the position of the bracket. It has been recognized for many years that the exact positioning of the bracket is of utmost importance in the efficient application of biomechanical force1. A new bracket positioning guide has been developed with the Nemotec NemoCast Software. Some problems are always present when cementing brackets directly analogously and traditionally. In this article, the development and use of this bracket positioning guide for direct bonding and its advantages over the convensional technique will be presented and explained.

The case of a 43-year-old adult patient with a severe skeletal class III malocclusion (Wits -9.1mm), anterior crossbite and skeletal compression of the maxilla of 6mm by WALA is presented. The performed treatment in this patient consists of a skeletal maxilla disjunction without SARPE with the aid of a pure bone-borne supported expander (MICRO4-expander™) following a specific and personalized very slow disjunction protocol for adult patients. We call this the activation protocol with polycyclic force control (CFPC protocol, explained in a 2 PART). Once the disjunction of the maxilla has been completed and its desired width is achieved, the case is finalized with an orthognathic surgery that consists of an advancement of the maxilla followed by a reduction mentoplasty. In the edentulous areas, conventional dental implants were placed that served as anchors to solve the lower dental crowding with a discrete distalization of the lower premolars.

Dental problems and malocclusions in children should be diagnosed with multidisciplinary approach which should include appropriate prevention, diagnosis and eruption controls. A case of a 13-year-old female with anterior and left posterior crossbite, 1.5 and 2.5 included and 3.7 and 4.7 impacted is shown. In order to achieve good function, aesthetics and stability, a maxillary rapid expansion, extractions and finally restorations on the anterior front were proposed. The treatment was completed in 35 months, obtaining a molar and canine class I with a correct overjet and overbite. [ABSTRACT FROM AUTHOR]

A 12-year-old skeletal class III patient with open bite and compression is presented. To obtain a good occlusal and facial result, it was proposed to treat the case by means of maxillary protraction with a facial mask anchored on micro-screws and the Alt-RAMEC protocol. [ABSTRACT FROM AUTHOR]

Currently, orthodontic treatment in adults is becoming very frequent. The treatment plan approach always has an interdisciplinary consideration. Achieving excellent coordination between dental specialties will be a key factor for success and guarantee periodontal and temporomandibular joint health, improve aesthetics, stability and function. A case of a 39-year-old woman with dental class II malocclusion, anterior open bite, compression and temporomandibular dysfunction is presented. Her chief complaint was lack of aesthetics in her smile and pain in the area of the masticatory musculature. After six months with a superior occlusal splint, condylar stabilization was achieved, making muscle pain disappear and discovering a different occlusal scheme from the usual occlusion. Under these circumstances an orthodontic treatment plan was designed in both arches to correct the malocclusion. This included the extraction of the upper and lower premolars and the vertical control of the posterior sectors by temporary skeletal anchorage device. The treatment was completed in 32 months with fixed appliances (MBT slot 0.22 technique), achieving a class I sagittal relationship with correct overjet and overbite. The final upper incisor exposure was correct, closing the anterior open bite and aesthetically improving the smile. [ABSTRACT FROM AUTHOR]
