The level of tooth wear was recorded for 100 persons using the tooth wear index of Smith and Knight. Aetiology was assessed using a history/questionnaire/examination. Erosion/attrition were postulated in 98 persons while abrasion was present in 82. All demonstrated some tooth wear and in 6.93% of 7,822 surfaces this was defined as pathological according to the threshold levels associated with the index. 84 persons had pathological wear on some surfaces but this was predominately cervical, only 12 persons showing pathological wear on the occlusal/incisal surfaces. Occlusal contact area was measured using imprints in soft opaque wax, transmitted light and a charge-coupled linear scanning array. The array is moved at 90 degrees to its axis by a linear translator to produce an image consisting of 1,600 lines, each of 2,048 pixels. This image is converted to hard copy using a DEC DDP 11/23 computer which will also give area measurements. Occlusal contact area ranged from 3.16 to 194.40 sq mm with a mean of 59.23 sq mm. Tooth wear is a significant clinical problem in this population. Wear on the occlusal/incisal surfaces is more common in older age groups and in males but could not be related to occlusal contact area or denture status by the methods used.</p>","PeriodicalId":77606,"journal":{"name":"Restorative dentistry","volume":"6 4","pages":"8-11"},"PeriodicalIF":0.0,"publicationDate":"1990-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13232598","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}

The lute thickness varied between 10 microns and 90 microns, and was found to be thinnest and most uniform in the region of occlusal cavosurface margins. Although the marginal adaptation of the inlays investigated was generally considered to be satisfactory, sections of the lute were found to exhibit porosity and to contain a number of voids. It is concluded that whilst the lute thickness and marginal adaptation of composite bonded inlays of the type investigated may be found to be acceptable, further work is desirable to investigate ways to limit porosity and voids in lutes and to form and finish the cavomarginal elements of tooth-coloured inlays in such a way that the limiting layer of luting material may be better protected from the rigors of function in the oral environment.</p>","PeriodicalId":77606,"journal":{"name":"Restorative dentistry","volume":"6 4","pages":"16-8"},"PeriodicalIF":0.0,"publicationDate":"1990-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13232697","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}

Two-part resin bonded cast metal bridges for use when abutment teeth have unequal effective root surface areas. 两部分树脂粘接铸造金属桥，用于基牙有效牙根表面积不等的情况。

{"title":"Two-part resin bonded cast metal bridges for use when abutment teeth have unequal effective root surface areas.","authors":"P M Dummer,&nbsp;J R Gidden","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Resin bonded cast metal bridges have become a popular method of replacing missing teeth. Such bridges are usually constructed as single castings following modifications to the abutment teeth in order to ensure a distinct path of insertion and to secure maximum metal to tooth contact. Unfortunately, long term retention of resin bonded bridges cannot be guaranteed and many surveys have reported substantial failure rates, particularly in the posterior segments of the mouth. It is the authors contention that many of these failures occur because clinicians are neglecting one of the fundamental principles of fixed bridge prosthodontics, namely that abutment teeth should be matched for effective root surface area (bony support). This article describes how problems created by incompatible abutment teeth can be overcome successfully by the construction of resin bonded bridges in two parts which are cemented separately, but interlock to provide a movable joint. Such an arrangement allows independent movement of the abutment teeth whilst providing sufficient retention and support for the bridge. The two-part design can also overcome problems created by malaligned abutment teeth as well as allowing conventional full crown retainers to be combined with resin bonded retainers.</p>","PeriodicalId":77606,"journal":{"name":"Restorative dentistry","volume":"6 3","pages":"9-14"},"PeriodicalIF":0.0,"publicationDate":"1990-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13435697","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}
