The Congress will take place in Iasi, 8 - 10, December, 2011, and is organised in collaboration with Romanian Dental Association for Education (ADRE) and the Faculty of Dental Medicine of the "Gr. T. Popa" University of Medicine and Pharmacy, Iasi, under the aegis of CMDR Iasi. The field of oral rehabilitation is the result of some experiences accumulation and competences in dental medicine that assumes access to new concepts and technologies which makes it one of the most dynamic brunches of medicine. The Romanian Society for Oral Rehabilitation supports progress in this field and offers to all interested parties its own means of promotion but also education in dental medicine. The Romanian Journal of Oral Rehabilitation, the post-graduate courses, the European Programmes and the Centre for Specialisation and Resource Formation in Oral Rehabilitation, all come to support and prepare for obtaining competences in different fields of dental medicine. At its V-th edition, this Congress organised by ASRRO already demonstrated a level of maturity, supported by the subject which is a call for rigour, competence, in one word, excellence. We hope that the new and pleasant opportunity to meet again on Moldavian ground will contribute to a fruitful experience and knowledge exchange among high level specialists and practitioners attending this event. We warmly invite you to our congress with the conviction and with the firm believe that we can actively contribute to enhancement of communication and cooperation in this area of common interest.

T. Popa" University of Medicine and Pharmacy, Iași, Romania ABSTRACT If you don’t replace a lateral missing tooth, you will be looking at a series of changes in the entire mouth. You may have the migration if adiacent teeth and of the antagonist tooth, changing the occlusion, also periodontal problems and cavities. In every one of these cases the prosthetic treatment becomes more difficult. In today’s literature we don’t have depicted all the consequences of alveolar bone loss. The purpose of this study was to determine the negative modifications registered after the tooth removal. Using radiographic investigations, we calculate the distance between the edentulous’s space and adiacent teeth to estimate the changes in the teeth position. Key words: alveolar bone loss INTRODUCTION result we have in all the cases an average of Loss of space was significantly associated 6.9 months. The Rx analysis has shown no with alveolar bone loss for the pre-molar but significant difference (0.05) on all parameters. not the molar.

Correlations in TL Thus, changes in tooth position in these sample showed the same patterns, but the cases were examined separately. Finally, we small sample size prevented any coefficient compared change in the cases in which from being statistically significant.
