title: [Pre-implant esthetic study].
abstract: The first dental prostheses used on Branemark implants were aesthetically disappointing both for the dentists and their patients. Therefore the authors will consider the various aesthetic problems encountered when treating loss of teeth with implant systems. The problems related to resorption are numerous: large bone losses are resolved by adapting removable acrylic, carrying out bone transplants immediately fixed by the implants, using filling materials, or complete dentures fixed with attachments supported by the implants. Periodontal surgery often provides a solution to the problem of gum visibility at the level of the maxillary anterior teeth. The problems related to the site where implants emerge can often be avoided by consultation between the surgeon and the prosthodontist and by flexing a surgical guide compiled from a pre-prosthetic analysis of the clinical situation. The aesthetic problems related to the actual implant systems are dependent on three factors: When the prosthesis is directly screwed onto the implant, the axis of the implant determines the axis of the dental prosthesis and can lead to the emergence of the screw on the buccal surface; With angulated cores, orientated screws provide the required solution. The implant material, when metallic leads to an unsightly border at the gingival level. Ceramic implants, or the "ceraming" of titanium, provide a solution to this problem. In case of diastema the use of an implant system gives the best choice in comparison to the more conventional treatments. In conclusion, the authors point out the importance of pre-implant analysis which must give an evaluation of the aesthetic result. The fragility of the aesthetic evaluation should encourage dentists to obtain the "clear and written consent" of their patients, accepting the risks run by treatment of this kind.
