Resumen

FARIAS, Daniel et al. Horizontal Augmentation Using “Tent Pole” Technique in Posterior Mandible. Int. J. Odontostomat. [online]. 2020, vol.14, n.2, pp.242-248. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2020000200242.

Bone augmentation prior to implant placement, is among strategies that should be considered to reduce morbidity rates in these procedures. The objective of this research was to define bone augmentation generator using the "tent pole " technique in the posterior jaw. A longitudinal, prospective study was designed, and subjects were included with ridge width no greater than 4 mm, height no less than 9 mm from the upper margin of the inferior alveolar canal. Surgeries were performed under local anesthesia for surgical approach; 2 to 4 osteosynthesis screws over ridge with 4 mm of the extra osseous screws were installed and were then regenerated, using allogeneic biomaterial and L-PRF together with an absorbable biological membrane. Re-entry was performed after four months and cone beam computed tomography analysis was used to confirm bone gain. Fourteen subjects were operated with 27 surgical sites; in all the cases, implant installation was possible at 4 months. In the initial evaluation, bone width observed was between 1.2 and 4.0 mm (average of 2.95 ± 0.75 mm); after 4 months of the horizontal increase, width was recorded at 3.79 and 10.05 mm (average of 7.15 mm ± 1.87 mm), confirming an average bone increase of 4.2 ± 1.26 mm. The difference obtained was significant (p <0.05). It can be concluded that the “tent pole” technique applied in this analysis is predictable in bone augmentation and applicable for implant rehabilitation.
