One had implants placed at 90° to the horizontal plane, and the other at 75°. Ten impressions were made each of stock metal tray, closed custom tray and open custom tray techniques. Photographs were taken and measure ments were made using Adobe Photoshop software. Intragroup comparisons were done using the analysis of variance (ANOVA) and one way ttest. Intergroup comparison was done using two way ttest. Results: All the techniques studied showed some distortion and the difference had no statistical significance. However, closed custom tray technique gave better results for the 90° specimen, and open custom tray technique gave better results for the 75° specimen. Conclusion: Within the limitations of this study, it can be con cluded that provided operator error is minimized and guide lines are followed, it may be possible to achieve impressions of similar accuracy regardless of technique used. However, it was impossible to achieve a level of exactness that would ensure a completely passive fitting prosthesis.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129616065","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}

Methodology: An experimental model was prepared on which three unit screw retained implant superstructure on two implant analogs (cortex system) was fabricated which was then subjected to spark erosion. Sheffield test (one screw test) was carried out to determine the passivity. Assessment of vertical discrepancy was carried out using stereomicroscopic images of the superstructure and implant analog junction pre- and post-spark erosion with the help of image J analysis software. Results: The implant superstructure fabricated with the conventional casting method were fitting actively on the implant analogs indicating a negative Sheffield test. However, following spark erosion passive fit was achieved. The marginal fit of the cast implant superstructure measured from a reference point on the superstructure to the implant analog margin was 4324.56 μm before spark erosion and 4046.57 μm after spark erosion.

Materials and methods: Ten patients with inadequate bone for implant placement were included in this study. Of these 10 patients with inadequate bone volume, five were chosen to be treated with autogenous bone grafts (AT) and rest five patients were treated with freeze dried corticocancellous allografts (AL). Three months following grafting, biopsies of the grafted area were obtained using a 3 mm trephine bur and were histologically evaluated. Results: Histological analysis revealed areas of new bone formation with thick trabeculae with lacunae containing osteo cytes in the autogenous group, whereas the allograft group showed segments of necrotic bone with empty lacunae. Although, the AL group has an inherent advantage of avoidance of a secondary surgical site, showed decreased bone remodeling as compared to the autografts. Conclusion: All the 10 patients underwent implant placement. The reports regarding the nature of bone obtained during implant placement clearly depicts a comparable histological variation at the grafted site.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131303862","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}

Background: Rehabilitation of a patient with maxillary anteriors with labially placed implant is always a challenge for a prosthodontist. If prefabricated abutments are used, labial contour would be too bulky that the implant-supported prosthesis would be out of arch. Case description: This case series describes the use of patient specific abutments which are restored with zirconia prosthesis for optimal esthetics and function. This article also discusses the problems faced while rehabilitating such cases. Conclusion: Unique surgical concepts are implemented for proper results to obtain ideal prosthetic restoration for missing teeth in esthetic regions. If surgical management is not chosen, prosthetically these cases can be managed by the use of customized abutments as described in this clinical report. Clinical significance: Use of patient specific abutments as describe in this article resulted in satisfactory restoration in terms of function and esthetics in the critical maxillary anterior region.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127222140","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}

One of the major current challenges is oral rehabilitation after tooth loss, due to fracture. Esthetic and functional results, together with periodontal health, predict success and prognosis. Implant dentistry provides the solutions for the placement of osseointegrated screw-retained implants or cemented prostheses to replace missing teeth. Careful use of provisional prostheses preserves the harmonious architecture of gingival tissues and affects final treatment results positively. This study describes series of three clinical cases of root fracture of maxillary anterior teeth, which had been previously endodontically treated. The teeth were extracted, immediate implants were placed and the provisional prostheses were fabricated and immediately loaded. The use of an immediate provisional restoration is a viable technique that has good esthetic and functional results and preserves gingival architecture and provides excellent esthetic result for the patient.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132403541","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}

These two types of implants are not only differentiated by the way they are inserted but also by the way the forces are transmitted. The purpose of this study is to compare the micromotion between two crestal and one basal implant-supported crown, when the mesiodistal space is 14 mm in mandibular 1st molar region. Materials and methods: A three-dimensional finite ele ment method was used to evaluate the micromotion in two osseointegrated crestal implants and one basally osseointe grated implant when the mesiodistal space is 14 mm in mandibular 1st molar region. The loads were applied according to cuspmarginal ridge relation. A total of 333 N and 645 N of load was applied to premolar and each molar respectively. The results were analyzed using Von Mises criteria. Results: The results of the comparison of crestal and basal implant to replace mandibular first molar demonstrated that micromotion in crestal implant (14.545) was less than basal implant (36.031). Conclusion: Thus, within the limitations of this study, it can be concluded that the use of two crestal implants to replace a missing mandibular first molar with mesiodistal edentulous space of 14 mm is a preferable option as compared to basal implant to replace a missing mandibular molar.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121438912","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}
