Implants--peri-implant (hard and soft tissue) interactions in health and disease: the impact of explosion of implant manufacturers.","authors":"Saso Ivanovski","doi":"","DOIUrl":"","url":null,"abstract":"1. The best-documented implants have a threaded solid screw-type design and are manufactured from commercially pure (grade IV) titanium. There is good evidence to support implants ≥ 6 mm in length, and ≥ 3 mm in diameter. 2. Integrity of the seal between the abutment and the implant is important for several reasons, including minimization of mechanical and biological complications and maintaining marginal bone levels. Although the ideal design features of the implant-abutment connection have not been determined, an internal connection, micro-grooves at the implant collar, and horizontal offset of the implant-abutment junction (platform switch) appear to impart favorable properties. 3. Implants with moderately rough implant surfaces provide advantages over machined surfaces in terms of the speed and extent of osseointegration. While the favorable performances of both minimally and moderately rough surfaces are supported by long-term data, moderately rough surfaces provide superior outcomes in compromised sites, such as the posterior maxilla. 4. Although plaque is critical in the progression of peri-implantitis, the disease has a multi-factorial aetiology, and may be influenced by poor integrity of the abutment/implant connection. Iatrogenic factors, such as the introduction of a foreign body. (e.g., cement) below the mucosal margin, can be important contributors. 5. Clinicians should exercise caution when using a particular implant system, ensuring that the implant design is appropriate and supported by scientific evidence. Central to this is access to and participation in quality education on the impact that implant characteristics can have on clinical outcomes. Caution should be exercised in utilizing non-genuine restorative componentry that may lead to a poor implant-abutment fit and subsequent technical and biological complications.","PeriodicalId":17281,"journal":{"name":"Journal of the International Academy of Periodontology","volume":"17 1 Suppl","pages":"57-68"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33125050","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}

A vertical force of 100 N and a 15-degree oblique force of 100 N were applied separately on the occlusal surface, and von Misses stresses were evaluated in the cortical and cancellous bone.Results: Higher stress was observed under oblique loading than under vertical loading of both tapered and cylindrical implants. Tapered implants demonstrated more stress under both vertical and oblique loading. Platform switching reduced peri-implant crestal bone stress in all models under vertical and oblique forces. The peri-implant crestal bone around tapered implants experienced 4.8% more stress under vertical loading and 35% more stress under oblique loading in comparison to bone around cylindrical implants (2.62 MPa with vertical loading, 8.11 MPa under oblique loading). Oblique loads resulted in much higher stress concentrations in the peri-implant crestal bone than vertical loads (238% in cylindrical and 308% in tapered implants). When the abutment diameter decreased, both models showed reductions of stress in the crestal bone under both types of loading.Conclusion: In this finite element analysis, tapered implants increased crestal bone stress upon loading, and platform switching minimized the stress transmitted to the crestal bone in both tapered and parallel wall implants.","PeriodicalId":17281,"journal":{"name":"Journal of the International Academy of Periodontology","volume":"17 1","pages":"2-13"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34059164","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 present study aims to assess the effect of academic stress on plaque and gingival health among dental students of Moradabad, India.Methods: Fifty eligible dental students (age 18 - 22 years) undergoing university examinations participated in the study. Students were examined for plaque index (PII) and gingival index (GI) scores during and after their examinations. Stress levels (using the DASS 21 questionnaire) and oral hygiene behavior were also assessed during and after university examinations and the data were subjected to statistical analysis.Results: The average PII and GI were 1.213 and 0.944, respectively, during examinations and 0.845 and 0.467, respectively, after examinations. The average stress scores were 15.66 and 9.94 during and after examinations, respectively. Eighty-eight percent of the students brushed once and 12% of the students brushed twice during the university examinations, whereas 76% brushed once and 24% of the students brushed twice after their examinations. Thirty-four percent of the subjects rated their thoroughness of brushing as good during university examinations whereas the percentage increased to 80% after the examinations. All the differences were found to be statistically significant.Conclusion: Students appearing for the university examinations showed increased stress levels. Moreover, under conditions of stress, the students generally neglected their oral health care and adverse effects on their plaque and gingival scores were observed. Thus, it might be concluded that academic stress has an adverse effect on plaque levels and gingival status in students.","PeriodicalId":17281,"journal":{"name":"Journal of the International Academy of Periodontology","volume":"16 4","pages":"115-20"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33031528","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}

Some studies demonstrated that patients undergoing surgery experience significant reductions in systemic vitamin C levels, presumably due to higher metabolic utilization of existing vitamin pools. However, there appear to be no studies evaluating the effect of non-surgical periodontal therapy on plasma levels of vitamin C. The aim of this study was to evaluate if non-surgical periodontal therapy is able to reduce the plasmatic level of ascorbic acid (AA) in smokers. Twenty-six systemically healthy adult (> 40 years) smokers (10 cigarettes/day for > 5 years) who needed scaling and root planing (SRP) for chronic periodontitis were recruited. The sessions of SRP (per quadrant) were scheduled 7 days apart from each other. Blood was collected by venipuncture before the first session of SRP and at the end of the periodontal treatment. The ascorbate concentrations in plasma were assessed according to a published protocol. A paired t-test (p < 0.05) evaluated the statistical significance of differences between the mean values obtained pre- and post-treatment. In general, there was no significant change in levels of AA; however, in 38% of patients, increased levels of AA in plasma were observed after SRP. In 15% of the patients, no change was noted, while 47% of patients showed a reduction in levels of AA after SRP. It can be concluded that although almost half of individuals presented with reduced levels of ascorbic acid after treatment, SRP did not significantly change the levels of AA in smokers.","PeriodicalId":17281,"journal":{"name":"Journal of the International Academy of Periodontology","volume":"16 4","pages":"109-14"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33031616","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 aim of the present study was to assess the association between metabolic syndrome and periodontal disease in an Indian population.Methods: Clinical criteria for metabolic syndrome included 1) abdominal obesity; 2) increased triglycerides; 3) decreased high-density lipoprotein cholesterol; 4) hypertension or current use of hypertension medication; and 5) high fasting plasma glucose. Serum C-reactive protein (CRP) levels were also measured. Periodontal parameters including gingival index (GI) average and deepest probing depth (PD) and clinical attachment level (CAL) were recorded on randomly selected quadrants, one maxillary and one mandibular. Based on the presence or absence of metabolic syndrome, individuals were divided into two groups.Results: The periodontal parameters PD, CAL and GI differed significantly between the two groups. The GI values in Group 1 (2.06 ± 0.57) were greater than in Group 2 (1.79 ± 0.66; p = 0.0025). Similarly PD and CAL values in Group 1 (4.58 ± 1.69 and 2.63 ± 1.61 mm) were significantly greater (p < 0.001) than in Group 2 (3.59 ± 1.61 and 1.61 ± 1.40 mm, respectively). Also, three metabolic components and serum CRP correlated with average PD, and the strength of the correlation was medium in Group 1 as compared to Group 2, in which it was weak.Conclusion: The association between metabolic syndrome and periodontal disease was significant, and abdominal obesity appeared to be the most important contributing metabolic factor to periodontal disease.","PeriodicalId":17281,"journal":{"name":"Journal of the International Academy of Periodontology","volume":"16 4","pages":"98-102"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33031614","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}
