[The implant denture in the laboratory]. [实验室中的种植义齿]。

{"title":"[The implant denture in the laboratory].","authors":"G M Scortecci,&nbsp;J Crousillat,&nbsp;P Foesser,&nbsp;B Bourbon","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The authors analyzed the numerous devices and prosthetic kits currently available for implant prosthodontics. Existing systems can be classified into two fundamentally different categories: the gold ring cylinder (or its equivalent in resin for casting) and the prosthetic abutment core or post concept. The former is based on connection of two nearly flat, horizontal surfaces by means of a screw, which avoids problems of parallelism; the latter can be likened to insertion of one part into another, like a crown that slides along the vertical axis of an abutment, with connection being obtained by cementation and/or screwing. Prosthetic abutment core or post: Whether monoblock or multiblock, the implant core or post is very similar to a conventional metallic abutment. Construction of the implant prosthesis is generally no problem when parallelism has been respected during surgery; if problems are encountered with parallelism, options include: 1. Adjustment of the abutment core by grinding, 2. Use of a telescope to achieve parallelism, 3. Use of a bendable prosthetic abutment core, 4. Use of a prosthetic abutment core preangulated 10 degrees-20 degrees, 5. A combination of the above solutions. The implant prostheses may be screwed, cemented or clipped in position. Gold ring cylinder concept The gold ring cylinder (or its equivalent in resin for casting) theoretically eliminates problems of parallelism, but at the same time restricts the implant prosthesis to screw techniques. A special protocol is required for the impression and construction of the prosthesis. Impression with plaster is often the best method for total edentulism whereas \"open\" impression trays are advisable for partial prostheses. In the laboratory, use of a machined gold ring cylinder provides optimum precision, but intra-oral verification remains necessary. Implant prosthodontics unquestionably represent a new type of \"know how\": both the dentist and the dental lab technician must acquire the necessary training and adapt their work routines.</p>","PeriodicalId":76114,"journal":{"name":"Les Cahiers de prothese","volume":" 67","pages":"88-103"},"PeriodicalIF":0.0,"publicationDate":"1989-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13841239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their own devices, increasingly ingenious, all display certain advantages and shortcomings. The need for a device more appropriate to the needs of day-to-day odontological use has been felt for some time. By giving a broad explanation of how it works, we have tried to assess the possibilities of the proposed prototype, the Cinetic. It measures movement of the dentalium in all three dimensions simultaneously. Since its reliability, when tested by a study concerning a sample of 40 patients, proved entirely satisfactory, a more sophisticated version was promptly devised. This latest Cinetic allows the ROZENCWEIG dyskinesia index, to be calculated, the FARRAR diagram to be drawn, and the mastication movements to be analysed by giving a visual display of the mandibular opening and closing trajectories, the speed diagram, the duration of the cycle, mandibular velocity and acceleration, and a breakdown of the cycles for each respective side. In order to be fully competitive, the Cinetic lacks the capacity to record and analyse condylar movement. Work on incorporating these features is currently at an experimental stage.</p>","PeriodicalId":76114,"journal":{"name":"Les Cahiers de prothese","volume":" 66","pages":"90-100"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13771769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is possible to consider a functional integration of the corrections, by addition or subtraction to the occlusal surfaces of the teeth. For this purpose, we have established the conditions of a physiological concept of occlusion taking into account the efficiency of the masticatory apparatus through a velocity analysis. This is the N.M.C. concept or concept of Neuro-Muscular Compatibility. This concept has led us to define the ISCA (Intra-Cuspid Spatial Angle), represented by the angle defined in the three spatial planes, by the trajectory of the occlusal contact point of a cusp liding over its opposite, in any excursive opportunity. We have shortly reported the studies by Levin on the SIROGNATOGRAPH and the prospects resulting from these studies. Then, we have studied in greater details the Saphon VISI TRAINER III developed by HOBO and described the various potentials of its use in the GBM Laboratory in Vienna (France), with François DURET. We have also analyzed the specific points which seem to represent the weaknesses of this device and have outlined some solutions to this problem. This approach, within a clinical context, may at term give rise to a complex analyser-expert-system intends to facilitate the establishment of a reliable diagnosis and to control the physiological integration of our procedures. The establishment, at term, of parameters and constants of this function, will guide this progression towards success.</p>","PeriodicalId":76114,"journal":{"name":"Les Cahiers de prothese","volume":" 66","pages":"42-53"},"PeriodicalIF":0.0,"publicationDate":"1989-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13837600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
