The anterior sector PAR index was applied to pretreatment (T0), posttreatment (T1) and follow-up (T2) casts. Statistical analysis was performed using frequency and percentage distributions, T test, Anova I, Anova II and Manova; significance p = 0,05. <strong>Results:</strong> no association was found between upper and lower incisor inclination, alignment stability and PAR weighted score between T2-T1 (p&gt; 0,05). The PAR decreased 75,29% from T0 to T1 and 58,79% from T0 to T2, with a recurrence of 16,5%. There was no association between retainer type and PAR weighted score. From T0 to T2 there was an association between the interaction of the incisor inclination of upper (p = 0,03) and lower (p = 0,04), with the weighted total score of the PAR index. <strong>Conclusion:</strong> there was no association between the modification of the incisor inclination with the stability of the anterior sector. At the end of orthodontic treatment there was a high level of correction in the anterior-superior and inferior sector, however, there was a recurrence of 16,5%.</p> Juan Carlos Rodriguez-Ladino Sonia Patricia Plaza-Ruíz Judith Patricia Barrera-Chaparro Ivonne Liliana Barrero-Avellaneda Lizeth Meriño-Brochero Ángela Paola Ramírez-Herrera Copyright (c) 2022 Revista Facultad de Odontología Universidad de Antioquia 2022-09-13 2022-09-13 34 2 Strength of lithium disilicate ceramics bonded with two different adhesives <p><strong>Introduction:</strong> lithium disilicate ceramics are an excellent choice in rehabilitation, made with the technique of injection or machining. The aim of this study was to evaluate the influence of two adhesive systems on the values of binding resistance in injected and machined lithium disilicate ceramics. <strong>Methods:</strong> lithium disilicate disks, IPS e. were used Max CAD (Ivoclar Vivadent, Liechtenstein, Swiss), 10mm in diameter and 1mm in thickness embedded in PVC tubes. Was distributed in 4 working groups, 2 in injected lithium ceramics and 2 in machined, Palfique Bond and Tetric N-bond Universal adhesives were applied according to the group distribution, then photopolymerized for 10 seconds with led light bulb, Tygon® tubes were placed for filling with fluid resin; once the Tygon® tubes were removed. The samples were taken to a universal testing machine where the micro-spraying test was performed. <strong>Results:</strong> the most significant binding resistance values were found in lithium disisilicate ceramics adhered with the Palfique Bond and Tetric Bond adhesive having a significant difference (p= 0,001), the bond strength values of the Palfique Bond and Tetric Bond adhesive in injected ceramic did not differ significantly. <strong>Conclusion:</strong> machined lithium disilicate ceramics have better values of binding resistance to micro-spraying.</p> Karlla Elizabeth Pezo-Vargas Joyce Mariana Salinas-Francia John Alexis Domínguez Copyright (c) 2022 Revista Facultad de Odontología Universidad de Antioquia 2022-10-19 2022-10-19 34 2
