Performing this treatment for mentally disabled patients is a subject of discussion. The aim of this study was to evaluate the quality of life (QOL) after orthognathic surgery in disabled patients. Material and methods: Eight patients with mental disability who underwent orthognathic surgery between 2007 and 2017 participated in this study. Their family or guardian completed a questionnaire to assess modification in aesthetic, functional, and social abilities after orthognathic surgery. Complications, difficulties in maintaining postoperative cares were also recorded. Results: All patients had improvement in global facial aesthetic. 62.5% of the patients had improvement in self-esteem and confidence in social events. Regarding functional aspect, the main improvement was found in chewing (75%) and ability to move the jaw (75%). Two patients (25%) found that jaw noises and pain were worse after surgery. No major complication occurred. Postoperative care was hard to follow but no patient had to stop maxillomandibular fixation. Conclusion: On well selected cases, orthognathic surgery is a safe procedure which provides improvement in QOL in disabled patients.

Our aim is to describe the dental malocclusion associated with craniosynostosis, syndromic, or nonsyndromic, and also the treatment used and its stability. Material and Methods: This retrospective study included all patients who presented at our Department for facial growth monitoring and occlusal management following syndromic and nonsyndromic craniosynostosis. Inclusion began in January 1996 and ended in December 2015 to ensure sufficient follow-up. Orthognathic surgery was performed after the end of growth. Dental occlusion was evaluated clinically and radiographically. Results: Fifty-five patients were included with 18 syndromic cases. The majority of patients presented with class III malocclusion (69.1%), especially syndromic cases (94.7%) and brachycephalies (96.3%). Conversely, scaphocephalies are associated with class II malocclusions. Thirty-nine patients underwent orthodontic treatment associated with orthognathic surgery to correct their malocclusion. In 4 cases, optimal dental occlusion was achieved with orthodontic treatment alone. Forty patients achieved stable optimal final dental occlusion. Optimal dental occlusion was achieved in 76.9% of the nonsurgically treated craniosynostosis patients and 68.9% of the surgically treated craniosynostosis patients. Discussion: Sutural fusion induces a facial growth restrictions and dental malocclusions. Several mechanisms may be responsible for these malocclusions: positional anomaly of the jaws due to the cranial deformity, associated anomaly of the facial sutures, or osteocartilagenous system diseases. Early craniosynostosis management does not avoid the occurrence of malocclusion, which will require orthodontic treatment and orthognathic surgery for their management.

We present herein a retrospective study of 214 secondary cases followed over 22 years in order to assess the factors of successful management. Material and methods: The study focuses on the results of gingivoperiosteoplasty, and occlusal stability. Nine subgroups were identified, taking into account the age of the patients, the history of surgery on the alveolar region, and the presence or absence of skeletal discrepancy. Results: Results clearly demonstrate a higher rate of poor outcomes and failures in the multioperated population. The success rate of the graft is 80.82% in the multioperated population versus 100% non-multioperated population. Periodontitis problem or orthodontic difficulties affect 19.17% of the patient in the multioperated groups versus 12% in the other groups. Relapse, particularly the transversal dimension, is also found mostly in the multi...

While the use of three‐dimensional (3D) models has improved the understanding of complex craniofacial anatomy, no study has evaluated the impact of this teaching support on long‐term retention. Our randomized controlled trial was designed to compare the long‐term retention of information with 3D‐printed models of four types of craniosynostosis versus classic 3D reconstructions displayed in two‐dimensional (2D) among undergraduate students. All students benefited from the same standardized course followed by the manipulation of the learning tool associated with the group for 15 min. Long‐term retention was assessed by the capability to properly recognize different types of craniosynostosis 3 weeks after the course. Eighty‐five students were enrolled. Previous educational achievements and baseline visuospatial skills were similar between the groups. The bi...

The ideal bone harvest site and grafting procedure remains a point of contention in regards to obtaining optimal long-term results with sufficient bone quantity and density without serious complications. More recently, confronted with growing patient requests and biomaterials development, maxillofacial surgeons and dentists have been considering these issues as they relate to pre-implant surgery. This study sought to evaluate implant success rate and complications following pre-implant surgery with parietal bone grafting. Materials and methods: A retrospective study was carried out on patients who underwent maxillofacial reconstruction of different sites (symphysis, mandibular corpus, maxillary sinus and premaxilla) for the purpose of implant insertion. Results: 311 procedures in 211 patients were included. The implant osseointegration rate was around 95%. Clinical follow-up ranged from 10 months to 11 years. A secondary procedure was performed in 6.1% of cases and we noted no serious complications at the harvest site. Discussion: With good revascularization and osseointegration of the graft, the use of parietal bone leads to an implant success rate similar to that seen in the literature. Moreover, the use of this material results in few infections and low bone resorption provided there is strict immobilization of the graft and no tension on the soft tissue sutures. Conclusion: Parietal bone grafts technique possess the required qualities for the success of implant surgery, offering results at least as interesting as others using autogenous bone and with no serious complications on donor site.

However, the quality of the peri-implant soft tissues is often not optimal. The aim of this study was to evaluate and describe corrective techniques used to improve peri-implant soft tissues in patients with resected mandibles reconstructed with free fibula flaps. Methods: All patients with ablative mandibular defects reconstructed using free fibula flap who underwent endosseous implant rehabilitation from August 2011 to March 2013 in two tertiary care hospitals were included in the study. The reconstructed mandible was described based upon: site of the reconstructon, single/double barrel fibula and thickness of soft tissue. Soft tissue complications were described as soft tissue hyperplasia, inadequate attached mucosa and inadequate vestibular depth. The procedures done to improve the peri-implant soft tissue include extended vestibuloplasty, split thickness skin grafting, palatal connective tissue grafting either alone or in combination with or without prosthetic splints. Results: Eighteen patients with a total of 59 implants were included in the study. Most soft tissue complications were seen in patients with a single barrel fibula replacing the lateral segment followed by single barreled fibula in the anterior segment. Patients rehabilitated with double barrel fibula had the least amount of soft tissue problems. All patients benefited from secondary soft tissue corrective surgeries. A combination of extended vestibuloplasty with split thickness skin graft, immobilized with a prosthetic splint seemed to be the most effective strategy to improve the quality of peri-implant soft tissues. Conclusion: This paper presents a descriptive review of various methods to improve peri-implant soft tissue characteristics in reconstructed mandible. Disclosure: This project is a part of a larger study that is supported by a grant from ITI Foundation for the Promotion of Implantology, Switzerland.

Research paper thumbnail of Osseous and dental outcomes of primary gingivoperiosteoplasty with iliac bone graft: A radiological evaluation

Gingivoperiosteoplasty with bone grafting in mixed dentition has been a well-established procedure. We hypothesized that 1) performance of this surgery in deciduous dentition would provide favorable bone graft osseointegration, and 2) would improve the support of incisor teeth eruption, thereby avoiding maxillary growth disturbances. We conducted a retrospective study of clinical and tridimensional radiological data for 73 patients with alveolar clefts (with or without lip and palate clefts) who underwent gingivoperiosteoplasty with iliac bone graft in deciduous dentition. Pre-and post-operative Cone Beam Computed Tomography (CBCT) comparison allowed evaluation of the ratio between bone graft volume and initial cleft volume (BGV/ICV ratio), and measurement of central incisor teeth movements. This series of 73 patients included 44 males and 29 females, with a mean age of 5.5 years. Few complications were observed. Post-operative CBCT was performed at 7.4 months. The mean BGV/ICV ratio was 0.62. Axial rotation was significantly improved post-operatively (p=0.004). Gingivoperiosteoplasty with iliac bone graft is safe when performed in deciduous dentition and results in a sufficient bone graft volume to support lateral incisor eruption and upper central incisor tooth position improvement.

We compared the results obtained with those of standard coagulation tests in 104 patients: 20 non-pregnant women (controls) and 84 women in the first (T1, n=17), second (T2, n=9) and third (T3, n=58) trimesters of pregnancy. We measured the clotting time (CT), the maximum clot firmness (MCF), the early clot amplitude at 5 and 15 minutes (CA5, CA15) and the clot lysis index (CLI30) with four tests containing specific reagents. (a) The INTEM® test involving ellagic acid activated the intrinsic pathway and (b) the EXTEM® test using tissue factor triggered the extrinsic pathway; (c) The FIBTEM® test based on a platelet inhibitor (cytochalasin D) evaluated the contribution of fibrinogen to clot formation and (d) the APTEM® test was similar to the EXTEM but was based on inhibition in vitro of fibrinolysis by aprotinin. CT and CLI30 were not significantly...

Discussion: With good revascularization and osseointegration of the graft, the use of parietal bone leads to an implant success rate similar to that seen in the literature. Moreover, the use of this material results in few infections and low bone resorption provided there is strict immobilization of the graft and no tension on the soft tissue sutures. Conclusion: Parietal bone grafts technique possess the required qualities for the success of implant surgery, offering results at least as interesting as others using autogenous bone and with no serious complications on donor site.

However, the quality of the peri-implant soft tissues is often not optimal. The aim of this study was to evaluate and describe corrective techniques used to improve peri-implant soft tissues in patients with resected mandibles reconstructed with free fibula flaps. Methods: All patients with ablative mandibular defects reconstructed using free fibula flap who underwent endosseous implant rehabilitation from August 2011 to March 2013 in two tertiary care hospitals were included in the study. The reconstructed mandible was described based upon: site of the reconstructon, single/double barrel fibula and thickness of soft tissue. Soft tissue complications were described as soft tissue hyperplasia, inadequate attached mucosa and inadequate vestibular depth. The procedures done to improve the peri-implant soft tissue include extended vestibuloplasty, split thickness skin grafting, palatal connective tissue grafting either alone or in combination with or without prosthetic splints. Results: Eighteen patients with a total of 59 implants were included in the study. Most soft tissue complications were seen in patients with a single barrel fibula replacing the lateral segment followed by single barreled fibula in the anterior segment. Patients rehabilitated with double barrel fibula had the least amount of soft tissue problems. All patients benefited from secondary soft tissue corrective surgeries. A combination of extended vestibuloplasty with split thickness skin graft, immobilized with a prosthetic splint seemed to be the most effective strategy to improve the quality of peri-implant soft tissues. Conclusion: This paper presents a descriptive review of various methods to improve peri-implant soft tissue characteristics in reconstructed mandible. Disclosure: This project is a part of a larger study that is supported by a grant from ITI Foundation for the Promotion of Implantology, Switzerland.

Gingivoperiosteoplasty with bone grafting in mixed dentition has been a well-established procedure. We hypothesized that 1) performance of this surgery in deciduous dentition would provide favorable bone graft osseointegration, and 2) would improve the support of incisor teeth eruption, thereby avoiding maxillary growth disturbances. We conducted a retrospective study of clinical and tridimensional radiological data for 73 patients with alveolar clefts (with or without lip and palate clefts) who underwent gingivoperiosteoplasty with iliac bone graft in deciduous dentition. Pre-and post-operative Cone Beam Computed Tomography (CBCT) comparison allowed evaluation of the ratio between bone graft volume and initial cleft volume (BGV/ICV ratio), and measurement of central incisor teeth movements. This series of 73 patients included 44 males and 29 females, with a mean age of 5.5 years. Few complications were observed. Post-operative CBCT was performed at 7.4 months. The mean BGV/ICV ratio was 0.62. Axial rotation was significantly improved post-operatively (p=0.004). Gingivoperiosteoplasty with iliac bone graft is safe when performed in deciduous dentition and results in a sufficient bone graft volume to support lateral incisor eruption and upper central incisor tooth position improvement.

We compared the results obtained with those of standard coagulation tests in 104 patients: 20 non-pregnant women (controls) and 84 women in the first (T1, n=17), second (T2, n=9) and third (T3, n=58) trimesters of pregnancy. We measured the clotting time (CT), the maximum clot firmness (MCF), the early clot amplitude at 5 and 15 minutes (CA5, CA15) and the clot lysis index (CLI30) with four tests containing specific reagents. (a) The INTEM® test involving ellagic acid activated the intrinsic pathway and (b) the EXTEM® test using tissue factor triggered the extrinsic pathway; (c) The FIBTEM® test based on a platelet inhibitor (cytochalasin D) evaluated the contribution of fibrinogen to clot formation and (d) the APTEM® test was similar to the EXTEM but was based on inhibition in vitro of fibrinolysis by aprotinin. CT and CLI30 were not significantly...
