Skeletal stability and morbidity with self-reinforced P (l/dL) LA resorbable osteosynthesis in bimaxillary orthognathic surgery

Segmental stability in orthognathic surgery: Hydroxyapatite/Poly-l-lactide osteoconductive composite versus titanium miniplate osteosyntheses

“…Consistent with other studies evaluating bioabsorbable osteosyntheses, no significant difference in this study's group's instability and case numbers were found (Haers and Sailer, 1998;Kiely et al, 2006;Landes et al, 2007;Moure et al, 2012). Therefore within the limited number of patients, F-u-HA/PLLA osteosyntheses can be counted equally stable to titanium plates regarding maxillary advancements.…”

“…The F-u-HA/ PLLA group showed less relapse yet with smaller operative movement. While anterior positioning of the mandible is a movement with high stability also in resorbable osteosyntheses (Turvey et al, 2006;Proffit et al, 2007;Stockmann et al, 2010;Moure et al, 2012), the results show no significant differences between study and control groups.…”

“…Maxillary elongations are generally susceptible to relapse and less stable than maxillary advancements and impaction regardless of method of fixation (Proffit et al, 1991;Baker et al, 1992;Louis et al, 1993;Gosain et al, 1998;Bailey et al, 2004;Ueki et al, 2006;Proffit et al, 2007;Ballon et al, 2012;Moure et al, 2012). Within the present and compared studies, no bone reinforcements i.e., transplants have been placed in the osteotomy gaps and the osteosyntheses absorbed the complete bite forces.…”

“…Therefore comparable groups using similar assessment techniques are used for comparison in Table 7 (using the facial horizontal as reference line), with an emphasis on recent resorbable/bioabsorbable osteosyntheses results. Previous studies using earlier resorbable osteosyntheses have shown relapses may occur up to 1 year postoperatively (Haers and Sailer, 1998;Kiely et al, 2006;Landes et al, 2007;Stockmann et al, 2010;Moure et al, 2012). All later changes are a result of postoperative myofunctional and orthodontic influence or growth in young patients (Proffit et al, 2007).…”

A Patient With Severe Maxillary Gingival Exposure Treated With Combined Compression Osteogenesis of the Anterior Alveolar Bone and Conventional Le Fort I Osteotomy

“…Le Fort I (L-1) osteotomy is a popular technique for treating the maxilla as an orthognathic surgical treatment in facially deformed patients and induces a great outcome 7,8 . This technique can treat a patient with a long face by moving the bone segment upward after osteotomy.…”
