| Popis: | Buccal orthodontic tooth movement (OTM) of the anterior teeth out of the osseous envelope of the alveolar process incase of front teeth crowding may be associated with a higher tendency for developing gingival recessions. The aim ofthis case report is to present the effectiveness of a minimally invasive preorthodontic corticotomy combined with a buccalbone augmentation according to the rules of periodontally accelerated osteogenic orthodontics (PAOO). The maingoal of our therapy is to increase or maintain the buccal bone thickness, which could prevent the development of gingivalrecessions. Corticotomy possibly have an additional benefit throughout regional acceleratory phenomenon, reducingthe duration of OTM in the early treatment phases. A generally and periodontally healthy individual at the age of17 presenting crowding and thin bone morphotype in the mandibular y front area, who requiresting OTM with incisorproclination, was treated. Surgery was performed under local anesthesia. Three vertical incisions were performed onthe midline and on both sides between lateral incisors and canines, with preservation of the papilla integrity. Incisionswere connected by tunneling knifes in 2 layers, subperiosteally in the whole length and supraperiosteally apically fromthe mucogingival junction. Corticocisions were utilized by ultrasonic instrument penetrating through the cortical bone.“Sticky bone” plates, a combinations of platelet rich fibrin (PRF) and xenograft, were used subperiosteally for bone, andPRF membranes supraperiosteally for soft tissue augmentation. Initiation of OTM started 1 week postoperatively, andactivation of the multibond appliance was performed activated in 2 weeks. The extent of tooth movement measuredon the central incisor was compared followed-up on cephalometric radiographs made taken at the different treatmenttime appointments, while buccal bone thickness on the 6 front teeth was evaluated in CBCT before and after OTM. Thealignment phase ended up at the 20th week due to an initial arch wire sequence using light forces. The buccal bony wallthicknesses showed similar values compared to the initial ones, and there was no radiologically proven substantial verticalbone loss. The presented comprehensive treatment approach promised a good option in the prevention of the periodontalside effects during orthodontic treatment. |
