[Body posture and craniofacial morphology].

The body posture has been studied according to the craniofacial morphology. A cephalometric analysis (lateral cephalometric radiographs) and a stabilometric recording of the posture with a vertical force platform have been done for 45 individuals: 17 boys and 28 girls aged 9 to 16 years. Cephalometric sagittal and transverse variables show no correlation with the sagittal position of the center of foot pressure. It seems that mild to moderate dentofacial deformities do not reflect on the posture of the body as a whole.

The applicability of osseointegrated implants in the treatment of partially edentulous patients: three-year results of a prospective multicenter study.

Nine clinical centers using the Brånemark System participated in a prospective study of 159 partially edentulous patients between 18 and 70 years of age. Clinical parameters evaluated were Plaque Index, gingivitis, pocket depth, Bleeding Index, tooth mobility, prosthesis stability, and stomatognathic function. Change in bone height around fixtures was measured radiographically. After 3 years, 460 loaded fixtures, supporting 174 prostheses in 139 patients, remain in the study. The complications, failures, and technical problems are presented. After 3 years of this 5-year study, results suggest that implant-based treatment of partially edentulous patients may achieve a success rate comparable to that obtained in edentulous patients.

Three years postgraduate programme in orthodontics. Final report Erasmus project.

A new curriculum with a common contents of 75%, leaving 25% for electives has been developed for a three year programme for specialty education in orthodontics. The result is a joint effort of the original eight participants and invited professors from Italy and Ireland as well as from five non-EEC countries (Austria, Finland, Norway, Sweden and Switzerland). Unanimity among the 15 participants was reached on all essential matters and on the contents of the final report. The main objective of the programme has been defined and the different courses have been formulated in terms of goals to be accomplished in three levels of comprehension and by the minimal hours students must devote to each subject. Furthermore, procedures that should be mastered have been specified.

Are some multiple congenital anomalies with mental retardation (MCA/MR) the clinical expression of rare autosomal fragile sites?

A boy with MCA/MR and a fragile site (FS) at 8q22 opens the discussion of a possible association between a rare autosomal FS and an abnormal phenotype. The child was born after prenatal diagnosis of ureterohydronephrosis. He had facial dysmorphia and mental retardation (IQ = 40). The karyotype showed 8q22 FS in 12% of the cells obtained after addition of FUdR to the culture medium. No other etiologic factor was shown to be responsible for the MCA/MR syndrome. Several authors have reported a variety of neurodevelopmental abnormalities and mental retardation in individuals with rare FS expressed on chromosomes 2, 9, 10, 16 and 19. If rare FS predispose to phenotypic abnormalities what are the mechanisms?

Applicability of osseointegrated oral implants in the rehabilitation of partial edentulism: a prospective multicenter study on 558 fixtures.

Nine clinical centers using the Brånemark System participated in a prospective study of 159 partially edentulous patients between 18 and 70 years of age. Clinical parameters evaluated were plaque index, gingivitis, pocket depth, bleeding index, tooth mobility, and stomatognathic function. Initially, 558 fixtures were placed and 521 remained in the study following prosthesis placement (199 prostheses in 154 patients). Fixtures were lost or unaccounted for because of nonintegration prior to prosthesis fabrication (19), patient withdrawal (11), prosthodontic reasons (6), and failure during prosthetic procedures (1). Failure was primarily attributable to unfavorable bone quality, sex (more in males), and smaller fixture size. Complications and failure related to other patient characteristics are presented. After 1 year of a 5-year study, preliminary results suggest that a success rate equal to or better than that obtained with edentulous patients may be expected.

Psychological impact of osseointegrated dental implants.

This longitudinal study of 39 patients who underwent treatment involving osseointegrated implants examined problems in oral and psychosocial functioning, expectations and experiences of difficulties with surgery, satisfaction with surgery, body image, neuroticism, self-concept, and extroversion. Patients completed six questionnaires from before phase 1 surgery to the final recall appointment for the new prosthesis (12 to 18 months after phase 1 surgery). The most common problems reported before treatment were those associated with eating; esthetics was less of a concern. Significant improvements in all problem areas were observed immediately after phase 2 surgery. Expectations of surgery-related problems were generally consistent with experiences immediately after phase 1 surgery, but more negative than experiences following phase 2 surgery. Body image before treatment was most negative vis-à-vis teeth. Significant improvements were found not only regarding teeth, but also on facial, mouth, and even overall body image. Satisfaction scores were generally high, but showed continued improvements through the final assessment. The only group experiencing negative outcomes consisted of patients scoring high on neuroticism.

[Development of the fetal mandible of rats in transplants onto the chorioallantoic membrane of chick embryos].

The evolution of mandibles of 15 to 17 days old fetal rats has been studied after transplantation on the chorio-allantoïc membrane of chicken embryos. The histological study of the samples grafts showed a remarkable adaptation of Meckel cartilage to the transplantation medium as well as the continuation of the ossification processes of membranous and endochondral origin. An important thickening of the oral epithelium, accompanied by an increased keratinization appeared in the grafts collected at 17 days "in utero". Only one tooth germ could be found in a graft collected at 17 days "in utero".
