Virtual surgical planning in orthognathic surgery: A prospective evaluation of postoperative accuracy.

Objectives: The development of 3D computer-assisted technologies over the past years has led to vast improvements in orthognathic surgery. The aim of the present study was to evaluate differences in maxillary position between 3D virtual surgical planning (VSP) and surgical results.

Materials And Methods: We assessed data from 25 patients who underwent bimaxillary non-segmented orthognathic surgery with 3D VSP.

Dental anomalies in craniofacial microsomia and condylo-mandibular dysplasia: A retrospective study of 103 patients.

Introduction: Craniofacial microsomia (CFM) and camel-hump condylo-mandibular dysplasia (CMD) are developmental disorders affecting the mandible that share common clinical features. This study aimed to investigate and compare the dental anomalies (DA) between the two entities for differential diagnosis and to propose appropriate treatment.

Methods: This retrospective cross-sectional study was based on panoramic radiographs of patients diagnosed with CFM or CMD.

3D analysis of condylar and mandibular remodeling one year after intra-oral ramus vertical lengthening osteotomy.

Objectives: Among the existing techniques for the correction of mandibular posterior vertical insufficiency (PVI), the intra-oral ramus vertical lengthening osteotomy (IORVLO) can be proposed as it allows simultaneous correction of mandibular height and retrusion. This study assessed the 3D morpho-anatomical changes of the ramus-condyle unit and occlusal stability after IORVLO.

Materials And Methods: This retrospective analysis compared immediate and 1-year post-operative 3D CBCT reconstructions.

Stability of Le Fort 1 osteotomy in patients with bilateral cleft lip and palate: A retrospective study of 71 patients.

The aim of this study was to evaluate the sagittal and vertical relapses after Le Fort 1 osteotomy in bilateral cleft lip and palate (BCLP) patients. Lateral cephalograms before surgery, immediately after the procedure, at one year, and at least two years (when available) after surgery were superimposed. The positions of five landmarks were studied in a coordinate system.

Alveolar bone changes in the mandibular incisors after genioplasty, a three-dimensional study.

Introduction: Functional genioplasty aims to achieve lip competence at rest and reduces lip pressure against the mandibular incisors. The purpose of this study was to describe the radiographic changes in alveolar bone of the mandibular incisors after functional genioplasty.

Materials And Methods: Cone beam CT images from 36 patients were compared between immediate (T0) and delayed postoperative period (T1).

Long-term vertical stability of horseshoe osteotomy for the correction of large vertical excess of the maxilla, a retrospective assessment in 15 patients.

Introduction: Vertical stability after a Le Fort I (LF1) osteotomy with substantial upward movement can be compromised by the position and the volume of the inferior turbinate. A horseshoe (HS) osteotomy represents then an alternative as it preserves the hard palate and the intranasal volume. The aim of this study was to assess the vertical stability of the maxilla after HS osteotomy.

Alveolar bone changes after tooth-borne surgically assisted rapid maxillary expansion: A three-dimensional study.

Introduction: Surgically assisted rapid maxillary expansion (SARME) with a dental-anchorage appliance can induce dental and skeletal complications adjacent to the teeth supporting the device. The purpose of this study was to quantify the dentoskeletal changes observed after SARME using a tooth-borne device.

Materials And Methods: Cone beam CT images from 39 patients were compared between the preoperative (T1) and the postoperative period (T2).

Impact of Orthodontic Gap Closure versus Prosthetic Replacement of Missing Maxillary Lateral Incisor on Dental Arch Relationships and Symmetry in 212 Patients with Cleft Palate: Retrospective Study.

Background: Maxillary lateral incisors are frequently missing in patients with cleft lip and/or palate. The aim of this study was to assess how orthodontic gap closure or prosthetic rehabilitation of the missing maxillary lateral incisor affected dental arch relationships and symmetry at the end of treatment. The authors also aimed to determine the effect of the level of oral hygiene on the decision made to manage the missing maxillary lateral incisor gap.

Surgical Repositioning of the Premaxilla: Incidence, Indications and Growth Study About a 189 Bilateral Cleft Lip ± Palate Population.

Objective: We aimed to evaluate the rate of patient requiring Surgical Repositioning of the Premaxilla in a population carrying BCL  ±  P, retrieve age and operative indication. Our secondary objective was to present further facial growth characteristics.

Settings: This was a retrospective, single-center cohort study conducted in Nantes University Hospital, Oral and Maxillofacial Surgery department, tertiary cleft center.

Outcomes of functional treatment of condylar mandibular fractures with an articular impact: a retrospective study of 108 children.

Introduction: The treatment of fractures of the mandibular condylar process remains controversial, especially in children. The aim of this study was to assess the long-term clinical and radiographic outcomes of functional treatments for mandibular condylar fractures with an articular impact.

Materials And Methods: Young patients (< 15 years of age) presenting with either a unilateral or a bilateral mandibular fracture of the condylar process were included in this retrospective study.

Evaluation of vertical ramus osteotomy for the surgical correction of unilateral mandibular posterior vertical insufficiency: Long-term follow-up results.

Purpose: Unilateral posterior vertical insufficiency (PVI) is a growth defect of the mandibular condyle that results in a facial asymmetry. Various surgical procedures can be used to elongate the hypoplastic ramus. The aim of this study was to evaluate long-term aesthetic and architectural outcomes of vertical ramus osteotomy (VRO) in patients with unilateral PVI.

Familial autosomal dominant severe ankyloglossia with tooth abnormalities.

Ankyloglossia is a congenital oral anomaly characterized by the presence of a hypertrophic and short lingual frenulum. Mutations in the gene encoding the transcription factor TBX22 have been involved in isolated ankyloglossia and X-linked cleft palate. The knockout of Lgr5 in mice results in ankyloglossia.

Progressive Atrial Conduction Defects Associated With Bone Malformation Caused by a Connexin-45 Mutation.

Background: Inherited cardiac conduction disease is a rare bradyarrhythmia associated with mutations in various genes that affect action potential propagation. It is often characterized by isolated conduction disturbance of the His-Purkinje system, but it is rarely described as a syndromic form.

Objectives: The authors sought to identify the genetic defect in families with a novel bradyarrhythmia syndrome associated with bone malformation.

Efficacy of proportional condylectomy in a treatment protocol for unilateral condylar hyperplasia: A review of 73 cases.

Introduction: Unilateral condylar hyperplasia (UCH) is characterized by an excessive growth of a mandibular condyle, resulting in facial, and occlusal deformities. Scintigraphic hyperactivity usually triggers the need of condylectomy. Delaire has presented a protocol for the treatment of active or non-active UCH using systematically a proportional condylectomy, which could solve both aetiology and adaptive deformities.
