Transverse maxillary insufficiency is one of the many dysmorphoses present in modern man. Since masticatory function is more affected by changes in diet and lifestyle, the stimulation of growth of the alveolar processes is weaker. The constriction of the maxilla is often the cause of dentomaxillary dysharmonia which requires space to be found on the arch. Expansion or extraction? This question has always stirred up our profession through the centuries. However, the main part of these treatments is to obtain a stable occlusion in the long term and for this, management of the functional equilibrium is paramount. The neuromuscular environment participating in the morphogenesis of the dental arches, it is essential to take into account all these factors to potentiate the success of our treatments and to promote a harmonious.

By the results of an exploratory research, we were able to put forward the specificity of the request in ortho-surgical protocol. Even if many studies evaluated correlations between psychological profiles and postoperative dissatisfaction, no one asked for the link between initial request and postoperative dissatisfaction. We suggest setting up an observation and forwardlooking research's protocol: 100 patients must been followed in a longitudinal way during 3 years (medium time between the first consultation and 6 months after the surgery). The whole duration of the study is about 4 years. It's divided in three times: treatment's proposal, preoperative hospitalization's day, postoperative hospitalization's day (three psychological interviews after the auto-administration of a clinical questionnaire, the Rathus Scale, the Hamilton depression and anxiety scale and the SF-36 quality of life scale. The research's main objective is to study the correlation between initial request and the satisfaction level. The second objectives are the evaluation of self-respect, anxiety, depression, and quality of life scales at the three times of the research, and the evaluation of the psychological following's impact on the results. Thirdly, we want to set up a questionnaire upon the initial request to help the practitioners. [ABSTRACT FROM AUTHOR]

Humans have an unusual life history, with an early weaning age, long childhood, late first reproduction, short interbirth intervals, and long lifespan. In contrast, great apes wean later, reproduce earlier, and have longer intervals between births. Despite 80 y of speculation, the origins of these developmental patterns in Homo sapiens remain unknown. Because they record daily growth during formation, teeth provide important insights, revealing that australopithecines and early Homo had more rapid ontogenies than recent humans. Dental development in later Homo species has been intensely debated, most notably the issue of whether Neanderthals and H. sapiens differ. Here we apply synchrotron virtual histology to a geographically and temporally diverse sample of Middle Paleolithic juveniles, including Neanderthals, to assess tooth formation and calculate age at death from dental microstructure. We find that most Neanderthal tooth crowns grew more rapidly than modern human teeth, resulting in significantly faster dental maturation. In contrast, Middle Paleolithic H. sapiens juveniles show greater similarity to recent humans. These findings are consistent with recent cranial and molecular evidence for subtle developmental differences between Neanderthals and H. sapiens. When compared with earlier hominin taxa, both Neanderthals and H. sapiens have extended the duration of dental development. This period of dental immaturity is particularly prolonged in modern humans., Human Evolutionary Biology
