Stability of Skeletal Class III Malocclusion After Combined Maxillary and Mandibular Procedures: Titanium Versus Resorbable Plates and Screws for Maxillary Fixation

Maxillary stability after Le Fort I osteotomy with self-setting α-tricalcium phosphate and an absorbable plate

“…In the study by Cheung et al 5 maxilla with bioresorbable plate fixation (2.0 compact plating system, Inion Ltd., Tampere, Finland) were confirmed to have minimal relapse compared to titanium plate fixation starting from the 6 th postoperative week, but vertical instability occurred in the early postoperative period. Costa et al 6 found that superior displacement of the maxilla occurred mainly within the first 8 postoperative weeks in the study with Lactsorb®. On the other hand, in our previous study using the PLLA plate (Fixsorb®-MX), we found that the maxilla was stable in the horizontal plane but tended to displace superiorly following Le Fort I osteotomy with SSRO or IVRO.…”

Maxillary stability after Le Fort I osteotomy using three different plate systems

“…In the study by Cheung et al 3 , maxilla with bioresorbable plate fixation (2.0 compact plating system, Inion Ltd., Tampere, Finland) were confirmed to have minimal relapse compared to titanium plate fixation starting from the 6 th postoperative week, but vertical instability occurred in the early postoperative period. Costa et al 4 found that superior displacement of the maxilla occurred mainly within the first 8 postoperative weeks in the study with Lactsorb®. On the other hand, in our previous study using the PLLA plate (Fixsorb®-MX), we found that the maxilla was stable in the horizontal plane but tended to displace superiorly following Le Fort I osteotomy with SSRO or IVRO.…”

Comparison of maxillary stability after Le Fort I osteotomy for occlusal cant correction surgery and maxillary advanced surgery

“…[13][14][15][16][17] Skeletal stability following orthognathic surgery is generally better horizontally than vertically. Simultaneous superior repositioning of the maxilla and advancement of the mandible is commonly employed to correct excessive anterior face height combined with mandibular deficiency.…”
