“…Este estudio analizo datos de ortodoncia con la poblacion objetivo (adolescentes) del Servicio Público de Salud de Chile, aunque la literaura disponible permite concluir que la edad no juega un rol critico en la duracion de los tratamientos como lo concluido por Mabreas et al (2008), Bichara et al (2016), Dyer et al (1991) y Robb et al (1998).…”

Factores que afectan la duración de los tratamientos de ortodoncia en un Servicio Público de Salud. Int. J. Odontostomat., 13(3):321-324, 2019. RESUMEN: La duración de los tratamientos de ortodoncia siempre ha sido una de las mayores preocupaciones, tanto en los pacientes como en los Ortodoncistas. El proposito de esta investigacion fue determinar la magnitud de las inasistencias a los controles por parte de los pacientes y como estas y otras variables, influyen en la duración de los tratamientos de Ortodoncia en el Centro de Salud Familiar (CESFAM) Dr. Victor Manuel Fernandez, Servicio de Salud de Concepcion, Chile. Se realizo un estudio descriptivo, de tipo transversal, retrospectivo, en el que se utilizaron las fichas clínicas de todos los pacientes que fueron dados de alta por los Ortodoncistas del CESFAM Dr. V. M. F. durante el año 2017. La tabulación se realizó en Microsoft Excel y el análisis estadístico se hizo en InfoStat 17. Se incluyeron 246 pacientes, con una edad de ingreso promedio de 13,6 años. La maloclusion predominante fue la Clase I de Angle (71 %). Estos pacientes tuvieron una duracion de tratamiento promedio de 33,9 meses. Se concluyó que a mayor cantidad de inasistencias, el tratamiento de ortodoncia tuvo una duración mayor.PALABRAS CLAVE: ortodoncia, duración de tratamiento, efectividad del tratamiento.

“…The impact of time on the treatment efficiency has been previously published. 24 A sample of 70 patients with Class I and Class II malocclusion treated by the same orthodontist during the same time period as the cases included in this study was considered. The aim was to determine whether or not there was a correlation between the year when treatment was started and the duration of orthodontic treatment.…”

Objective: The purpose of this study was to assess the efficiency of compensatory orthodontic treatment of patients with mild Class III malocclusion with two preadjusted bracket systems. Method: Fifty-six matched patients consecutively treated for mild Class III malocclusion through compensatory dentoalveolar movements were retrospectively evaluated after analysis of orthodontic records. The sample was divided into two groups according to the brackets used: Group 1 = non-Class III compensated preadjusted brackets, Roth prescription (n = 28); Group 2 = compensated Class III preadjusted brackets, Capelozza III prescription (n = 28). Cephalometric analysis, number of appointments and missed appointments, months using Class III elastics, and bond/band failures were considered. Treatment time, Peer Assessment Rating (PAR) index at the beginning (PAR T1) and end of treatment (PAR T2) were used to calculate treatment efficiency. Comparison was performed using a MANOVA at p< 0.05. Results: Missed appointments, bond or band failures, number of months using the Class III intermaxillary elastics, and cephalometric measurements showed no statistically significant difference (p> 0.05) between groups. Patients treated with Roth brackets had a treatment time 7 months longer (p= 0.01). Significant improvement in the patient’s occlusion (PAR T2-T1) was observed for both groups without difference (p= 0.22). Conclusions: Orthodontic brackets designed for compensation of mild Class III malocclusions appear to be more efficient than non-compensated straight-wire prescription brackets. Treatment time for Class III patients treated with brackets designed for compensation was shorter than with Roth prescription and no difference in the quality of the occlusal outcome was observed. A prospective randomized study is suggested to provide a deeper look into this subject.

“…19 Failures in either bonded or banded tubes are an important variable and require further investigation given their likely influence on treatment time. 9,20 Moreover, future studies on the survival rate of bonding and banding of molar attachments in adult patients should seek to assess periodontal changes and the occurrence of white spots and to perform a comparative analysis of operators with different levels of experience.…”

Survival analysis of banding and bonding molar tubes in adult patients over a 12-month period: a split-mouth randomized clinical trial

This split-mouth randomized clinical trial aimed to compare the survival rate of bonding and banding molar tubes in adult orthodontic patients. Eligibility criteria included adults (aged >18 years), no active caries, restorations, or fractures in the upper and lower molars. The main outcome was any type of first-time failure in molar tubes. A computer-generated randomization scheme was used in a 1:1 ratio. The survival rate was estimated for 32 adult patients, in whom a tube was bonded to a molar tooth using composite resin on one side and a band was cemented with glass ionomer onto the same tooth in the contralateral arch. A total of 59 banded and 59 bonded molars were followed up for 12 months. Blinding was not applicable. Survival analysis including Cox regression was used at p < 0.05. The survival rate of bonded molars was not statistically different from that of banded molars (log-rank test, p = 0.97). Hazard ratio (HR) was 0.72 (95%CI, 0.38-1.31). Bonded upper molars yielded a survival rate of 81.25% (26 out of 32) compared to 71.87% (23 out of 32) for banded upper molars. The survival rate was 66.66% (18 out of 27) for banded lower molars and 59.25% for bonded lower molars (16 out of 27). The HR for lower vs. upper arch was 2.16 (95%CI, 1.18-3.98). No serious problem was observed other than gingivitis associated with plaque accumulation. In contrast to previous studies in young patients, in adults, bonding orthodontic tubes to molars is similar to molar banding. However, both procedures had a high failure rate in the lower arch.
