[Immediate placement of an implant after extraction: indications and surgical requirements].

Following the extraction of a tooth, a 3 to 6 months period of healing is generally necessary before a screwed or impacted titanium implant can be placed. After what, another 3 to 6 months period is necessary before it is possible to expose the implant and put it to function. Nonetheless, in some clinical situations, and under certain surgical conditions, it has become apparent that the immediate positioning of an implant after extraction is currently possible and even recommended, thus ensuring an aesthetic and psychological advantage for the patient.

[Pre-implant esthetic study].

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.

[Panorama of prosthetic options in osseointegrated implantology].

Today, several prosthetic options can be used with osseointegrated implants. Fixed bridges may be retained by screws or cemented. Detachable bridges may be screwed on cylindrical, conical, straight or angulated abutments. In certain cases, they will be placed directly in contact with the implants. Cemented bridges may be placed over screwed, cemented or transfixed copings. They also may be cemented over transfixed metallic structures already splinting the implants. Removable prosthesis may be stabilized with bars, stud attachments or magnets. All these different options are discussed, and their advantages and disadvantages presented.

[Complete luxation with loss of the tooth: an implant case].

The purpose of this article is to report a possible use of dental implants in children. The immediate implantation of an aluminium artificial frialite root, is described in an 8 years old child following the complete avulsion with loss of her center incisor. Osteo integration and the surgical placement technique of the Frialite implant are reviewed. The selection of an implant and of the immediate implantation concept are also discussed in this article. This implant will either become functional as a prosthetic abutment or esthetic by filling the alveolus, as it avoids the formation of a concavity in the edentulous ridge.

[Choice of sectional planes and advantages of the scanner in implantology].

The future site of the implant, close anatomical obstacles and the insertion axis of single various implants, can be determined by the use of the scanner. Giving precise instructions is very important in determining the selection of sectional planes to be used the radiologist such as: axial sections, direct or reconstructed frontal sections, sagittal or reconstructed sagittal oblique sections. Precise measures can be directly realized on the scanner. When it is impossible to obtain the orthogonality of all the sectional planes, correction of the measures can be realized by using the cosinus of the angle obtained by the effective sectional plane and the ideal plane.
