“…The magnitude of a moment to upright a molar varies around 1000 g.mm to 1500 g.mm. 18 Another study suggests that 1200 g mm is appropriate for molar uprighting. 19 As mentioned above, the type of uprighting spring and wire material play an important part in maintaining optimal force levels.…”

Introduction: Management of mutilated cases is challenging, and adult patients often require orthodontic correction of occlusion before prosthetic replacement of missing teeth. Objective: To highlight the novel, simple, hygienic, and efficient miniscrew-supported Beta titanium molybdenum alloy (TMA) cantilever spring for uprighting severe mesially tipped molars for interdisciplinary treatment. Diagnosis and Treatment: A 23-year-old male patient presented with skeletal Class I relation, average growth pattern, Class II Div 1 malocclusion with dentoalveolar collapse, crowding, multiple missing, supraerupted teeth, and severe mesially tipped mandibular third molars. MBT appliance with 0.022˝ slot was used to achieve the objectives. 38 and 48 were uprighted and protracted with miniscrew implant-supported TMA cantilever springs to substitute 37 and 47. Mild intrusion of maxillary posterior teeth was done with acrylic bite blocks and transpalatal arch (TPA), followed by prosthetic replacement of missing teeth. Results: The patient had a consonant smile arc and a pleasing soft tissue profile. Mandibular third molars were uprighted and protracted with good vertical control, and the mesial pockets were eliminated. The supraerupted maxillary molars were intruded, and group function occlusion was established. Class I canine relationship, normal overjet, and overbite were achieved. Conclusion: Miniscrew supported TMA cantilevers are efficient for uprighting of severely tipped third molars without extrusion, unlike the conventional mechanics. The third molars with good root forms can be protracted and substituted as second molars to minimize prosthetic rehabilitation.

“…In these cases, it is common to find infrabone defects in the mesial of the inclined molar, accompanied by a gingival recession, and a reduction of the interradicular space in the distal region [2]. Generating repercussions throughout the stomatognathic system, this unwanted movement leads to premature contact, food impaction, joint pain, and, eventually, difficulty in prosthetic rehabilitation [2]. One of the solutions for the rehabilitation of this region would be the verticalization of the "bent" molars, which would restore the parallelism of the teeth, mainly improving the incidence of occlusal forces on them [4].…”

This study investigated the effects of photobiomodulation (PBM) in acceleration of orthodontic movement of inferior molar uprighting movement. Thirty‐four individuals, with indication of molar uprighting movement for oral rehabilitation, were randomly divided in two groups: verticalization + PBM (808 nm, 100 mW, 1 J per point, 10 points and 25 J/cm2) or verticalization + PBM simulation. Elastomeric chain ligatures were changed every 30 days for 3 months. FBM was performed immediately, 24 h, 72 h, 1 and 2 months after activation. The primary outcome was the amount of uprighting movement. Secondary outcomes were pain, amount of medication, OHIP‐14 questionnaire, and cytokine IL‐1β. PBM group increase uprighting movement when compared to control after 3 months and modulate IL‐1β expression. For pain control, the amount of medication and OHIP‐14 no difference were found. This study suggests that PBM accelerates tooth movement during molar uprighting, due to modulation of IL‐1β during bone remodeling.

“…Entre los dispositivos, de titanio o sus aleaciones, para anclaje esquelético se pueden destacar tres principales: implantes oseointegrados, mini-implantes y miniplacas (Sekima et al, 2009). Los últimos 2, se encuentran dentro de los no osteointegrados, ya que se diseñan para uso temporal y/o sólo para la fijación de dos segmentos óseos, por lo que el acabado de la superficie lisa y pulida sumado a contaminantes propios de la fabricación, inhiben la oseointegración (Erverdi & Üsümez, 2010).…”

RESUMEN: En ortodoncia, las miniplacas se utilizan como dispositivo de anclaje temporal (TAD) para la realización de movimientos dentales que permiten el uso de fuerzas ortopédicas en ellos. En comparación con los mini tornillos, las miniplacas tienen la ventaja de una tasa de falla muy baja, pero la desventaja es que para la extracción se necesita el mismo acto quirúrgico que se realizó para la instalación. El objetivo de este estudio es realizar una revisión bibliográfica de las indicaciones de miniplacas en pacientes con mordidas abiertas, clase II y anomalías de clase III, y buscar cómo las miniplacas han mejorado los tratamientos de ortodoncia. La información principal se reunió buscando en PubMed con las palabras clave enumeradas a continuación. Afirmamos que las miniplacas están indicadas para la retracción en masa de la arcada, donde se observó que la fuerza de 150 g aplicada en los molares superiores es suficiente no solo para empujar los molares hacia atrás en una clase I corregida, sino también para iniciar la retracción de premolares, caninos e incisivos. En pacientes con mordida abierta, las miniplacas se definen como un método seguro, una alternativa rápida y menos costosa a la cirugía ortognática. Y en pacientes de las clases II y III se utilizan sin producir efectos dentoalveolares que sustituyan a los dispositivos extraorales como máscaras, con dispositivos intraorales y elásticos (BAMP). PALABRAS CLAVE: miniplaca de ortodoncia, minitornillo de ortodoncia, dispositivo de anclaje temporal, dispositivo de anclaje óseo, retracción maxilar de anclaje óseo (BAMP), anclaje esquelético.
