[Growth of the skull and bony kinetics interfering with facial morphogenesis. Conceptual bases of success in orthopedic treatments before the age of 6]. / Croissance crânienne et cinétiques osseuses interférant avec la morphogenèse faciale. Bases conceptuelles de réussite des traitements orthopédiques avant l'âge de 6 ans.

In order to perform an orthopedic treatment without relapse, one needs to identify properly the cranial patterns responsible for the malocclusion and act on them before the age of 6.

[Cranial asymmetries and their dento-facial and occlusal effects]. / Les déformations crâniennes asymétriques et leur retentissement dento-facial et occlusal.

Cases of occlusal asymmetry detected in the temporary dentition are frequently associated with skeletal asymmetries of the cranial base. They should be corrected as soon as possible. Symmetry of these dental groups is achieved with the use of mini-screws implanted in designated sectors of the hard palate. When a new occlusal plane derived from the corrected maxilla is obtained, the mandible will re-center itself in relation to it. As a result cranial bones can remodel and the possibility of induced temporo-mandibular disorders is greatly reduced.

[Cranial analysis for early treatment and the biodynamic concept of cranio-facial morphogenesis]. / Une analyse crânienne au service des traitements précoces et du concept biodynamique de la morphogenèse cranio-faciale.

The understanding of the background of a malocclusion is essential especially in the cranial field. Statistics reinforce the choice of our cranial landmarks and the main lines of our cranial biometry which is really 3D. It marks the relationships between the cranium and the face. It expresses the relevance of diagnosing and treating under 6 years of age.

[Analysis of various craniofacial architectural types using the ontogenic approach of humanization]. / Analyse des différents types architecturaux cranio-faciaux par l'approche ontogénique de l'hominisation.

A new concept of craniofacial growth and of the physiology of membranous sutures provides new insight into the different craniofacial architectural types encountered in modern Man. This is based on the hypothesis that cranial sutures reflect certain biodynamic laws pertaining to a phenomenon of craniofacial contraction that took place in the course of development over the ages. At present, craniofacial biodynamics is the sole concept capable of shedding light on matters such as the evolution of the skull, its diversification and transformation down from the primeval primates.

[Analysis of 144 spermocytograms (author's transl)]. / Analyse de 144 spermocytogrammes

PIP: Male responsibility is about 40% in all cases of marital infertility. Spermocytograms allow the researchers to isolate pure morphological syndromes, such as microcephaly, and are a valuable tool in prognosis, since the consequences of most such anomalies on the fertilizing power of the sperm are well known. 144 spermocytograms were done by the authors at the request of 144 sterile couples. The spermocytograms were classified according to the system proposed by David et al. In investigating the incidence and the importance of the various abnormalities it was noted that forms of lengthened heads were preponderant, while abnormalities in the flagella were rare. Spermocytograms were divided into pure and mixed syndromes: pure syndromes, with anomalies of a single type, permitted the prognosis of the fertilizing power of the sperm; and mixed syndromes, with anomalies of several types, permitted the identification of diseases such as varicocele.^ieng
