This article aims to show that the correction of mandibular retrognathia can
be carried out easily in a reduced time using minimally invasive means.

It details a procedure used for nearly twenty-five years and proven
over these years.
In addition to a few personal reflections on its mode of action, it will show that it can
also be used in adults, with convincing results.

Prospective study of 127 maxillary impacted canines: treatment duration and characterization of the population by A. Benhamou Giuly
Our prospective longitudinal multicenter study, conducted over 26 months including
12 months of inclusion, first focused on characterizing the sample, then on attempting
to establish a correlation between the initial position of a maxillary impacted canine and the duration
of treatment for its placement in the arch.
The protocol, based on the literature, involved 101 patients, i.e. 127 canines. The study begins on the day of the surgical exposure of the canine and ends when it is brought into management within a rectangular archwire.
The results show the existence of sexual dimorphism and a predominance of unilateral impaction. Measuring the alpha angle between the lateral incisor and the studied canine guides the treatment duration, which varies on average from 12 to 14 months.

Implement responsible LEAN in your practice. by F. Pourrat
In our professional life, we are increasingly confronted with regulations and increasingly restrictive notifications. The world of quality improvement allows us to integrate this into our daily routine in a smooth way. We are also increasingly faced with obligations and conflicts with our staff; it is the
“Investors in People” approach that can help us improve
as a manager. The other approach we want to propose to you is responsible LEAN, an approach that makes it possible to improve both quality improvement, human resources, and the flow management of process workflows.

The digital workflow and a CBCT cone: why do it? by P. Azoulay
3D imaging made a striking entry into dental practices in recent years. It has become an indispensable tool for diagnosis and treatment planning, as well as the best means of verifying these treatments,
particularly for endodontics, periodontology, and implantology.
In the field of orthodontics, this is obviously even more the case. This is what we will develop.

Pain psycho-physiology, aggravating circumstances by M.G. Choukroun
The article in the previous issue aimed to introduce health professionals—namely orthodontists—to the concept of managing suffering. Historically, medicine oriented itself toward contributions from anatomy and physiology to address the problem of pain. But some authors remind us that this approach is reductionist (BALINT, FREUD); for etymological reasons, we proposed to name this therapy “algotherapy.” Pain also involves a relationship to suffering that cannot be avoided by the physician. Another very interesting approach we would like to explore in this article is to identify the factors that aggravate pain, in order to deduce certain effective therapeutic actions. A classic methodology in medicine consists in exploring the pathological in order to deduce the normal. This was the approach taken by ANGLE, which enabled us to determine the keys to normal occlusion by studying malocclusions.
