Venkat Ratna Nag P. Sarika T. Bhagwatkar V. Dhara <p><strong>Aim</strong> Rehabilitation of maxillary edentulous arches is a challenging task for the Dentists. Angulated implants used for implant placement which utilizes bicortical engagement of implants at the nasal cortex and pterygoid region in a flapless manner. The aim of this study was to evaluate the clinical outcome when 6 tall angulated implants were placed in a maxilla and restored with screw-retained fixed prosthesis after 3 years follow up.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Methods</strong> Total of 40 patients were considered for implant placement in the maxilla, 20 patients who underwent implant placement followed by delayed loading and 20 patients who underwent the same surgical procedure followed by immediate loading. Angulated implants were supported by Finite element analysis (FEA) comparing stress distribution on cortical, cancellous and basal bone on mesial and distal side of each implant with All-on-6 concept for maxillary arch. <span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Results </strong>Angulated implant shows 100% survival rate in implants and prosthesis, in both delayed and immediate loading protocols of maxillary rehabilitation. The FEA based on von Misses stress, shows little higher values for All-on-6 for cortical, cancellous and basal bone when compared with Angulated 6 implants design. <span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Conclusions</strong> Angulated implants a novel concept shows a good survival rate. Due to the bicortical engagement of implant the chances of marginal bone resorption around the implant, implant and prosthesis failure is minimal.</p> 2019-12-09T14:27:35+00:00 ##submission.copyrightStatement## Evaluation of implant stability and marginal bone loss in immediate implant using “nano bone” versus “autogenous bone” for the treatment of patients with unrestorable single tooth: a randomized controlled trial 2019-10-29T13:51:14+00:00 S. A. N. Adam A. E. Elarab A. R. A. Rahman D. F. Abel Rahim <p><strong>Aim</strong> A randomized controlled trial was conducted to evaluate the advantages of using nano-hydroxyapatite (nHA) bone graft compared to the "gold standard" autogenous bone graft in the jumping gap with immediate implants.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Materials and methods</strong> Immediate implant placement was performed for the treatment of patients with an unrestorable single tooth. All eligible patients, in total 18, were randomly selected and divided in two groups, controls (AG) and study group (NB), in equal proportions (9 for eah group). Six month later implants were surgically exposed and the measurements of the secondary outcomes were taken.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Results</strong> Implant stability outcomes showed no significant differences in the groups. Marginal bone level of both groups at baseline and after six months showed a significant difference, as<span class="Apple-converted-space">&nbsp; </span>bone loss occurred more in NB group than AG group.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Conclusion</strong> Within the limits of the present study the placement of NB graft in the jumping gap contributed in decreasing and reduced the morbidity of the donor site compared to autogenous bone (AB) group. Trial had been registered in both The Pan African Clinical Trials Registry (PACTR) PACTR201512001348246 and clinical NCT02613663.</p> 2019-10-28T15:32:21+00:00 ##submission.copyrightStatement## Antibacterial properties and side effects of chlorhexidine-based mouthwashes. A prospective, randomized clinical study 2019-10-29T13:51:14+00:00 E. Polizzi G. Tetè F. Bova G. Pantaleo G. Gastaldi P. Capparè E. Gherlone <p><strong>Aim</strong> Chlorhexidine (CHX) is commonly used in clinical applications, including plaque control and gingivitis treatment. The im of this study was to evaluate the clinical properties, in terms of plaque control, bleeding and discoloration levels, of six CHX mouthwashes that differ in the following characteristics: CHX concentration, presence/absence of alcohol and presence/absence of an anti-discoloration system (ADS).</p> <p><strong>Materials and methods</strong> A single-center, prospective, double-blind randomized clinical trial was carried out on 78 consecutive patients. Six mouthwashes (CHX 0.12% alcohol free; CHX 0.20% alcohol free; CHX 0.12% alcohol free with ADS; CHX 0.20% alcohol free with ADS; CHX 0.12% with alcohol; CHX 0.20% with alcohol) were tested. Plaque Index (PI) and Bleedind Index (BI) were recorded, along with tooth staining (spectrophotometry) at T0 (beginning), at T1 (after 7 days), at T2 (after 14 days), and T3 (after 21 days). Data obtained were subjected to statistical analysis.</p> <p><strong>Results</strong> All CHX mouthwashes significantly reduced PI (p&lt;0.0001), while only alcohol free CHX 0.20% significantly reduced BI (p&lt;0.0001). Only the CHX 0.12% with alcohol and CHX 0.20% with alcohol mouthwashes showed a significant presence of extrinsic tooth staining (p&lt;0.05).</p> <p><strong>Conclusions</strong> Within the limitations of the present study, the alcohol-free mouthwash CHX 0.20% allows a good control of the clinical indices, in particular the bleeding index.<span class="Apple-converted-space">&nbsp;</span></p> 2019-10-28T15:06:17+00:00 ##submission.copyrightStatement## Evaluation of the health of the peri-implant tissues around immediately placed dental implants in aggressive periodontitis patients versus periodontally healthy individuals in the maxillary esthetic zone: Controlled clinical trial 2019-09-25T11:50:11+00:00 N. M. Yussif A. R. Abdel Rahman M. Darhous <p class="p1"><span class="s1"><strong>Aim </strong>To evaluate the health condition of the immediately placed dental implants in aggressive periodontitis patients compared to periodontally healthy individuals after 12 months of follow up.</span></p> <p class="p1"><span class="s1"><strong>Materials and methods</strong> Following atraumatic tooth extraction, 70 implants were placed in two study groups: Thirty-five implants replaced hopeless teeth in aggressive periodontitis patients (test group) and thirty-five implants replaced periodontally healthy unrestrorable teeth (control group).&nbsp;</span></p> <p class="p1"><span class="s1"><strong>Results </strong>After 12 months, there were no dropouts in both groups. The criteria of the health scale showed 97.17% success in the test group versus 100% in the control group. Due to peri-implant mucosistis, only 2.85% implants in the test group showed satisfactory survival rate. It was also found that 20% of the inserted implants in both groups were covered with bone during the second stage surgery. Lack of pain, mobility, exudate and suppuration with no incidence of peri-implant diseases were clearly detected in both groups indicating the success rate. There was no statistical significant difference between the results in both groups. </span></p> <p class="p1"><span class="s1"><strong>Conclusions</strong><span class="Apple-converted-space">&nbsp; </span>The current study highlights that immediate placement did not affect health and survival of the implants in aggressive periodontitis patients. Nearly equal results were reported between periodontally healthy and periodontally affected patients. Long- term follow up studies are recommended to examine the failure rate that could not be reported in the current short-term study. </span></p> 2019-09-25T09:56:08+00:00 ##submission.copyrightStatement##
