On long-term maintenance of the osseointegrated response. 关于骨整合反应的长期维持。

Look-alike implants do not necessarily show similar long-term clinical results. Osseointegration of an implant is not the same as clinical success, as secondary loss of osseointegration may be a frequent problem with respect to certain biomaterials as well as implant designs. For instance, with respect to solid cylinders, there is no published report documenting that such implants ever establish a steady state with respect to bone height. A continuous bone loss of half a millimetre or more will inevitably jeopardise the outcome of the implant over follow-up times of five to ten years. The author suggests a new way of reporting the outcome of oral implants in a four field table with Success, Survival, Unaccounted for and Failure categories. Success applies to those implants that meet with specific Success criteria. Survival are those implants that are still in the jaw of the patient but where criteria for success or failure are not met. Unaccounted for are implants in patients who dropped out from the study for one reason or the other including patient death. Failures are those implants which have been removed from the jaw or where absolute failure criteria such as implant mobility or therapy-resistant pain apply.</p>","PeriodicalId":77024,"journal":{"name":"Australian prosthodontic journal","volume":"7 Suppl ","pages":"15-24"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19048209","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}

Desirable properties would be pronounced softness and resiliency, or visco elasticity. Compression tests of Molloplast B (a silicone rubber), Kurepeet (a fluoropolymer), Visco-gel (a tissue conditioner) and Xantopren ( a silicon impression material) (as control) showed a displacement of 4% and recovery to 0.4% permanent deformation after 15s of loading for Molloplast and Xantopren, and up to 32% and 13% displacement respectively for Visco-gel and Kurepeet followed by considerable permanent deformation. Recovery of the latter showed a typical curve for visco-elasticity. The small amount of initial deformation of the elastic materials on the other hand indicated unyielding and consequently unsatisfactory properties.

{"title":"Mechanical and biomechanical guidelines for the use of Brånemark System--general principles.","authors":"B Rangert","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The understanding of biomechanical principles increases in importance as the number of potential indications for implant treatment increases. Recognising these principles as they relate to specific treatment indications helps to prevent conditions leading to overload. One consequence of recent findings shows that prosthetic loading conditions could significantly differ in the partially edentulous or single tooth cases as opposed to full arch bridges. It is reasonable to imagine that if you can make a full arch bridge on 4 to 6 fixtures, then two fixtures would be more than enough support for the traditional three-unit bridge. However, full arch restorations are based on multiple fixtures spread in an arch form which allows the masticatory forces to load the implants generally in an axial direction. Axial forces, whether compressive or tensile in nature, provide favourable loading throughout the entire cross-sectional area of the implants, and the forces are distributed through a maximum bone/implant interface. On the other hand, in partial restorations, the implants are placed more along a straight line. Any straight line arrangement increases the possibility for bending forces on the implants around an axis of rotation. Bending has much poorer stress distribution patterns on both the components and the supporting bone than axial load.</p>","PeriodicalId":77024,"journal":{"name":"Australian prosthodontic journal","volume":"7 Suppl ","pages":"39-44"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19048211","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}

Simplified surgery, where the self-tapping fixture and a new surgical kit are important products. 3. Reduced contra-indications, mainly concentrating on the upper jaw, with contra-indications caused by resorbed bone or poor bone quality. 4. Obtaining increased understanding of biomechanical aspects.

In this paper, current concepts of the chemistry of demineralisation of the mineral components of teeth are examined, with view to their providing a better understanding of some of the clinical characteristics of dental erosion of enamel.
