Técnica de ortodoncia osteogénica periodontalmente acelerada: principios biológicos y etapa quirúrgica / Periodontally accelerated orthodontic and osteogenic technique: biological principles and surgical stage

La integración de la cirugía bucomaxilofacial con la ortodoncia, ya no sólo se limita al trabajo en equipo sobre pacentes con malformaciones bucomaxilofaciales (asociando ortodoncia y cirugía ortognática), sino también en otros múltiples procedimientos. El ortodoncista posee mayores opciones a la hora de planificar y el paciente mejores resultados estéticos y funcionales a mediano y largo plazo. Los pacientes adultos jóvenes demandan tratamientos funcionales y estéticos en el menor tiempo posible. La ortodoncia osteogénica periodontalmente acelerada permite: movimientos dentales acelerados, reducir el tiempo de tratamiento y mejorar el estado periodontal y biotipo gingival. En el presente trabajo analizamos las bases biológicas de la técnica y su etapa quirúrgica, junto con la presentación de un caso (AU)

The integration of oral and maxillofacial surgery with orthodontics is no longer limited to team work on patients with oral and maxillofacial malformations (associating orthodontics and orthognathic surgery), but also in other multiple procedures. The orthodontist has greater options when planning and the patient, better aesthetic and functional results in the medium and long term. Young adult patients demand functional and aesthetic treatments in the shortest possible time. Periodontally accelerated osteogenic orthodontics allow: accelerated dental movements, reduced treatment time and improve periodontal status and gingival biotype. In the present work, we analyze the biological bases of the technique and its surgical stage, together with the presentation of a case (AU)

Evaluation of the relative efficacy of an alloplast used alone and in conjunction with an osteoclast inhibitor in the treatment of human periodontal infrabony defects: A clinical and radiological study.

Background: Mucoperiosteal flap surgery stimulates varying amounts of alveolar bone loss due to accelerated osteoclastic activity [Regional Accelerated Phenomenon (RAP)]. Alendronate sodium inhibits osteoclastic activity and is thought to result in a net increase in osteoblastic activity. We undertook a preliminary study evaluating the effect of adjunctive use of topically delivered bisphosphonate alendronate (ALN) along with regenerative bone graft material in the treatment of periodontal infrabony defects. Materials and Methods: Fifteen patients with two-walled or three-walled infrabony defects were selected. In each patient, the infrabony defect of one side of arch was designated as group A (control site) and received hydroxyapatite (HA) bone graft material, while the infrabony defect on the contralateral side of same arch was designated as group B (test site) and received HA + 200 μg drug solution of ALN. Results: Both the groups exhibited a highly significant reduction in probing depth and gain in clinical attachment level and linear bone fill at the end of 24 weeks. Comparative evaluation between the study groups revealed a statistically nonsignificant reduction in probing depth (P=0.128 NS ) and mean gain in attachment level (P=0.218 NS ). However, there was a statistically significant gain in linear bone fill (P=0.040*) in group B as compared to group A. Conclusions: The results suggest that use of ALN along with graft material led to enhanced linear bone fill at the surgical site. This research provides a clue that bone-targeting properties of bisphosphonates can be harnessed along with regenerative materials to potentiate osseous regeneration.
