title: [Point of contact and cervical-proximal margin of occlusal-proximal restorations using amalgam. A clinical evaluation].
abstract: The occluso-proximal restorations should restore a coronary morphology permitting a normal physiology. The radiological evaluation of 55 occluso-proximal restorations with the  amalgam done by 4th and 5th years students at the Odonto-Stomatology Institute, and judged clinically  acceptable, has shown 63,63% of incorrect restorations with faults: of inter-dental contact (absence of contact or large contact area) and of cervico-proximal limit (hiatus or excess. The identified iatrogenic faults  come from choice of matrixing material in accordance with the clinical situation, to use of separators or inter-dental wedges. The radiographic control of these restorations has permit an immediate correction of excesses and some big areas of contacts, by improving appreciably the success score (up to 20% without re-doing the obstrusion with the amalgam). The retro-alveolar radiography  is a clinical evaluation instrument for a better periodontal integration of occlusoproximal restorations in the biological space and inter-proximal space.
