Mini-implants are increasingly popular for creating skeletal anchorage in clinical orthodontics. The aim of this article is to present and discuss the clinical uses, benefits and drawbacks of the miniscrew implants used to reorder and adjust the dento-alveolar morphology of the overerupted maxillary molars. The loss of the lower premolars and molars very often leads to overeruption of the opposing maxillary teeth, combined with insufficient space for prosthetic restorations. The available treatment options are either a significant reduction of the maxillary teeth, often associated with endodontic treatment, or a complex orthodontic treatment. In the previous years, different cases of orthodontic intrusion with mini-implants were described. In this report, the authors describe a case of a young patient who needed a maxillary molar intrusion in order to get sufficient prosthetic space for an implant supported fixed restoration in the third quadrant. This treatment type preserved maximum tooth structures and allowed a successful mandibular restoration.

[The value of studying the cervical spine in craniofacial asymmetries].

Introduction: The relationship between facial asymmetry and cervical anomaly is rarely mentioned in the diagnosis of dento-maxillo-facial orthopaedics. It is regrettable that the study of the cervical spine is often ignored in the etio-pathogenesis of these dysmorphoses, particularly in cases of facial asymmetry.
Objective: The aim is twofold: to encourage orthodontists and maxillofacial surgeons to make a systematic study of the cervical spine in craniofacial dysmorphoses and in particular craniofacial asymmetries, without claiming that they are becoming specialists in cervical spine pathology, and to introduce the necessary training in malformations of this anatomical region as part of the orthodontist specialisation curriculum.

: The long face type is associated with excessive vertical facial growth and most often with anterior open bite. In many cases of anterior open bite of high severity associated with bimaxillary dento-alveolar protrusion, lips are unable to form an adequate seal at rest. This leads to many issues, including facial dysmorphism.

Malocclusion is a global health problem, mainly affecting children and adolescents. For this reason, orthodontic treatment must be, on the one hand, safe, non-toxic, and effective and, on the other hand, it must have the best possible esthetic profile. Thus, the use of orthodontic appliances is addressed to all age groups, including young children, for a long period of time, which is why their safety profile is a matter of real interest.
