Observations On Succession Of The Clinico-Technical Steps Of Functional Impression Of The Maxilla With Libra Crest And Accentuate Bunoid Papilla

The aging process is viewed as a complex phenomenon of anatomical, physiological, metabolic and psychological decline of the human subject. Examination of the prosthetic field in the elderly must take into account the local anatomical peculiarities of the hard and soft oral structures. To obtain a correct functional impression a thorough history and physical examination are essential for finding out the characteristics of each field prosthetic in part. To obtain a correct final impression, a wide range of impression materials and techniques is available. Most often, to obtain the desired result several materials with different consistencies are used, and impression techniques are combined. A prosthetic restoration can become “part” of the stomatognathic system being assimilated and perfectly tolerated by the body or, on the contrary, it can cause patient discomfort and iatrogenesis. The quality of restoration depends on the selected treatment plan, practitioner knowledge and skills on the one hand, and patient status and responsiveness, on the other hand

THE USE OF ZX27 BIO-GLASS ABUTMENTS IN BITERMINAL EDENTATIONS TO SOLVE PROBLEMS OF MASTICATION AND PHYSIOGNOMY

International experience shows that ZX-27 bio-glass pillar or abutment can handle more difficult cases, usually biterminal edentation when, for various reasons, skeletal and/or telescope prostheses or implants cannot be made and works very well. The authors present their experience in using this innovative material that adapts perfectly to each patient, while providing optimal functional and aesthetic results through a technique with reduced costs and execution time

The assessment of the angiogenesis in the uterine cervix carcinogenesis

The uterine carcinoma represents one of the most frequent malignant tumors in female. Great progresses were made in the understanding of the mechanisms of the appearance and evolution of the tumors, and also in the early diagnosis of them. In the present time, the discussions are centered on the angiogenesis and the neovascularisation. During the researches regarding the new factors of prognosis in cervical carcinomas, we are interesting firstly in the study of neoangiogenesis and its predictive role. The microanatomic quantitative study was made on fragments which were processed from uterine cervix dysplasias, preinvasive and invasive tumors. The sections were stained specific immunohistochemically (CD34) and examined with an interactive digital program. We have quantified the density of the microvessels/mm2 tumor stroma and the density of the microvessels/mm2 tumor. The preliminary results regarding the study of the microvessels in uterine cervix carcinomas show a positive correlation between the density and the evolution of the tumor, the angiogenetic process rises simultaneously with the risk of metastasis. This study shows a significant correlation between the density of vessels and the evolution of the uterine cervix carcinomas, the appearance of recurrences and metastasis. The quantification of the angiogenesis is an indicator with an high degree of precision, with is used for the detection of the aggressiveness and malignancy of the uterine cervix tumors
