This study aims to compare bone-borne (BB) surgically assisted rapid maxillary expansion (SARME) to tooth-borne (TB) SARME with regard to dentoskeletal effects. Measurements were performed on 3D scanned cast models of 34 patients preoperatively and 20.5 ± 1.34 months post-expansion. Secondary variables were pterygomaxillary disjunction or not; bimaxillary(More)
Comparison of bone-borne (BB) versus tooth-borne (TB) distraction in surgically assisted rapid maxillary expansion, secondary variables were bipartite (2S) or tripartite (3S) osteotomy, pterygomaxillary osteotomy (+PP) or not (jPP), and age (920 years old [920] and G20 years old [G20]). Fifty patients received three-dimensional computed tomography(More)
To assess whether MRI is a suitable modality for the preoperative assessment and quantification of pectus excavatum. A total of 69 patients (57 male, 12 female; median age 15 years, range 5–35 years) with pectus excavatum were evaluated preoperatively using standardized MRI sequences on 1.5- and 3-Tesla systems (T2-HASTE/inspiration and expiration, T1-VIBE,(More)
This study (50 patients; Ø25 years) compared surgically assisted rapid maxillary expansion (SARME) with (±PP) to SARME without pterygomaxillary (−PP) disjunction due to dentoskeletal effects in 3D CT preoperatively and Ø11 weeks post-expansion. In t test, SARME−PP declined in transverse width from anterior to posterior but more symmetrically than SARME+PP.(More)
PURPOSE To evaluate tripartite paramedian versus bipartite median osteotomy in surgically assisted rapid maxillary expansion. Tripartite osteotomy was performed between the lateral incisors and canines at the former premaxillary junction to avoid midline diastema, septal and columellar dislocation, and asymmetric expansion, minimizing high-distraction(More)
After two decades of the use of resorbable miniplates, new polymer compositions for resorbable osteosynthesis are still being developed to make the handling and outcome of operations even more predictable and give higher stability to the repositioned segments. This study investigates a new resorbable osteosynthesis system in orthognathic patients. 50(More)
PURPOSE To assess surgically assisted rapid maxillary expansion (SARME) with or without pterygomaxillary disjunction using a thin volume-rendering technique in variance analysis and in reliability, accuracy, and validity. MATERIALS AND METHODS Thin volume-rendered images of 68 patients were evaluated preoperatively and 2.87 ± 1.59 months after expansion(More)
BACKGROUND This study evaluated whether personal expectations and satisfaction throughout orthognathic surgery were fulfilled. In addition, patients were interrogated about their experience of resorbable osteosynthesis. METHODS A total of 50 patients were interviewed 3 times each throughout the study by a mixed questionnaire of standard psychologic tests(More)
OBJECTIVE To evaluate whether symphyseal distraction for correction of mandibular transverse deficiencies and dental crowding provokes lateral shift of the condyles, because this may have secondary influence upon temporomandibular joint function. STUDY DESIGN Nine patients' routine pre- and postoperative computerized tomography scans were evaluated for(More)
OBJECTIVE To assess clinical, aesthetic, and quality-of-life parameters of cleft lip and palate patients' implant-supported crowns with ITI Straumann nonsubmerged and loaded after 3 months implants. PATIENTS, MATERIAL, AND METHODS In 17 bone-grafted cleft patients, 24 implants were placed nonsubmerged, loaded at 3 months to support crowns in the cleft(More)
