Due to the lack of high-level clinical evidence on the management of peri-implant bone loss, the authors, through a literature review, attempt to suggest a decision tree or guideline, based on sound periodontal surgical principles, to aid clinicians in managing peri-implantitis associated bone loss.
Researchers are in constant search for the ideal implant surface condition in an attempt to improve osseointegration of the implant and to increase bone-to-implant contact. Although introduction of rough surfaces was able to overcome a lot of limitations that presented with machined surfaces, they are still incapable of ensuring predictable results and guaranteed success. Various techniques in implant surface modifications have been proposed, all aimed at improving bone formation around dental implants. Understanding how surface modification of dental implants can impact osseointegration might help the clinician to maximize the success rate of implants and diminish the complications that can be encountered after their placement. In view of that, this article is aimed at assessing the different surface conditioning techniques available and will present a review of the literature that focuses on the influence of microdesign of dental implants on their osseointegration.
Aim: To compare the outcomes of surgical periodontal therapy with and without initial scaling and root planing. Methods: Twenty-four patients with severe chronic periodontitis were enrolled in this pilot, randomized controlled clinical trial. Patients were equally allocated into two treatment groups: Control group was treated with scaling and root planing, re-evaluation, followed by Modified Widman Flap surgery and test group received similar surgery without scaling and root planing. Clinical attachment level, probing depth and bleeding on probing were recorded. Standardized radiographs were analysed for linear bone change from baseline to 6 months. Wound fluid inflammatory biomarkers were also assessed. Results: Both groups exhibited statistically significant improvement in clinical attachment level and probing depth at 3 and 6 months compared to baseline. A statistically significant difference in probing depth reduction was found between the two groups at 3 and 6 months in favour of the control group. No statistically significant differences in biomarkers were detected between the groups. Conclusions: Combined scaling and root planing and surgery yielded greater probing depth reduction as compared to periodontal surgery without initial scaling and root planing.
Introduction: Foreign bodies have been reported in the maxillary sinus. It has been suggested that asymptomatic foreign bodies do not require removal. The effect of such retained foreign bodies on sinus-elevation procedures is unknown.Case Presentation: This case report documents the management of an asymptomatic foreign body embedded in the Schneiderian membrane. The foreign body was left in situ while elevating the membrane for a sinus-augmentation procedure. A staged approach with delayed implant placement was used. Leaving the foreign body in situ did not seem to adversely affect the healing or clinical success of the augmentation procedure.Conclusions: From this short-term follow-up case, a retained foreign body in the maxillary sinus consistent with periapical endodontic filling material could be left in place in conjunction with maxillary sinus grafting based on a lack of symptoms. Long-term clinical success has yet to be confirmed. Clin Adv Periodontics 2014;4:135-138.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
