Primary Failure of Dental Eruption Due to Variants Parathyroid Hormone Receptor 1: Retrospective Study and Proposal of Guidelines Treatment.

Objective: Primary failure of eruption is characterized by a nonsyndromic defect in tooth eruption in the absence of mechanical obstruction. It is correlated to rare heterozygous variants in the parathyroid hormone receptor 1 gene. The management of primary failure of eruption is complex because many therapies are ineffective.

AI-based diagnosis in mandibulofacial dysostosis with microcephaly using external ear shapes.

Introduction: Mandibulo-Facial Dysostosis with Microcephaly (MFDM) is a rare disease with a broad spectrum of symptoms, characterized by zygomatic and mandibular hypoplasia, microcephaly, and ear abnormalities. Here, we aimed at describing the external ear phenotype of MFDM patients, and train an Artificial Intelligence (AI)-based model to differentiate MFDM ears from non-syndromic control ears (binary classification), and from ears of the main differential diagnoses of this condition (multi-class classification): Treacher Collins (TC), Nager (NAFD) and CHARGE syndromes.

Methods: The training set contained 1,592 ear photographs, corresponding to 550 patients.

Three-dimensional Assessment of Autologous Calvarial Bone Grafting for Alveolar Clefts Reconstruction in Pediatric Population: A Retrospective Study.

Reconstruction of alveolar clefts using cancellous bone graft is associated with a high rate of resorption. The aim of this study was to evaluate the osseointegration capacity of cortical calvarial bone grafting using 3-dimensional imaging assessment for alveolar cleft reconstruction in pediatric population.All alveolar bone grafting procedures performed between January 2015 and October 2017 in the maxillofacial surgery department of Lille University Hospital were included.

Dental and maxillofacial manifestations of Steinert's myotonic dystrophy: A retrospective case series and therapeutic investigation.

This retrospective study was performed to analyse the facial features and occlusal anomalies in 18 patients with Steinert's myotonic dystrophy (MD1). Medical and surgical management issues noted in this study may contribute to clinical decision-making. This series included 18 patients with MD1 who presented for maxillofacial consultations.

Three-dimensional printing models improve long-term retention in medical education of pathoanatomy: A randomized controlled study.

Craniosynostosis is a rare and complex pathology, and visuospatial skills are necessary for a good understanding of the condition. 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.

Secondary Care of Cleft Lip and Palate: Analysis of Dentofacial Orthopedic and Orthognathic Treatments.

Introduction: Orthodontic and orthognathic management of cleft lip and/or palate (CLP) is a highly controversial subject. 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.

Orthognathic Surgery in Craniosynostosis.

Introduction: Craniosynostosis is characterized by the fusion of 1 or more sutures of the skull leading to craniofacial deformations. 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.

Temporomandibular Joint Dysplasia in Cranio-Maxillofacial Dysplasia: A Retrospective Study. Guideline Treatment Proposal.

Introduction: Cranio-Maxillofacial Dysplasias (CMD), including Craniofacial Microsomias, syndromes (such as Treacher Collins or Williams) and isolated Condylo-Mandibulo-Dysplasia, is a controversial subject with treatments as diverse as diagnostic classifications. The authors present here a retrospective study of 85 patients, with congenital condyle dysplasia arising from these 3 main types of CMD, treated with different techniques that aimed to normalize the facial skeleton and occlusion.

Methods: The authors studied retrospectively 85 patients, aged from 3 to 53 years old, affected by different types of CMD.

Implant-borne rehabilitation for alveolar dental cleft: Retrospective analysis of thirty-nine cases.

Introduction: Dental rehabilitation of patients with alveolar-dental cleft sequelae is a crucial issue in the final stages of functional and aesthetic management of these patients. The objectives of this study are to establish the success of implant-supported rehabilitations for patients with alveolar dental cleft sequelae followed in the Department of Maxillofacial Surgery and Stomatology of Lille University Hospital and the reasons for not using this type of rehabilitation for others.

Materials And Method: Patients treated between January 2009 and December 2018 with implant-supported prostheses at an alveolar dental cleft site were included.

Temporomandibular Joint Ankylosis Following Mandibular Distraction Osteogenesis: A Dreadful Complication.

Introduction: Mandibular distraction osteogenesis (MDO) is an effective treatment for severe micrognathia, as it helps to avoid tracheostomy but has some adverse effects on the temporomandibular joint (TMJ). TMJ ankylosis is a serious condition leading to feeding difficulties and growth impairment, and could result in worse consequences in cases with micrognathia who already have limited growth potential. Here, we aimed to report on cases with TMJ ankylosis-a rare but devastating complication of MDO.

Anatomic study of the arterial territories of the face depending on the external carotid artery branches.

Aim Of The Study: Blood supply of the skin of the face is mainly provided by 3 branches of the external carotid artery: facial artery (FA), superficial temporal artery (STA) and transverse facial artery (TFA) which is a branch of the STA. The aim of the study was to describe the arterial territories of the skin of the face depending on the external carotid branches.

Material And Methods: After dissection of the first two centimeters of these arteries on one side, we performed an injection of India ink of different colors in the arteries in order to describe the arterial territories (angiosomes) of the face on 24 embalmed cadavers.

Assessing Quality of Life After Orthognathic Surgery in Disabled Patients.

Introduction: Orthognathic surgery is a common procedure in facial deformities treatment but requires a high level of compliance from the patient. 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.

How to produce pre-shaped rigid arch bars using low-cost 3D printing technology - A technical note.

Numerous oral and maxillofacial procedures in dentate patients begin with the fixation of occlusions. While several techniques exist to perform mandibulo-maxillary fixation, many surgeons use arch bars in common practice. In cases of severe craniofacial traumas or jaw malformations, such as temporomandibular joint ankylosis, it may be impossible to use rigid arch bars.

[Surgical management of animal bites in children].

Children represent a population at risk, because of their short size, their naivety and their attraction to animals. The face and hands are the most specific locations in young children. Wounds are often multiple.

Retrospective evaluation of 211 patients with maxillofacial reconstruction using parietal bone graft for implants insertion.

Purpose: For a century, autologous bone grafts have been used in maxillofacial reconstruction. 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.

Osseous and dental outcomes of primary gingivoperiosteoplasty with iliac bone graft: A radiological evaluation.

Primary alveolar cleft repair has two main purposes: to restore normal morphology and normal function. 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.
