Filter by:Vitamin D is important for bone health, immune function, and inflammation, along with dental implant success. The study aimed to assess bone markers and cytokine levels in patients with and without vitamin D insufficiency to better understand the effects of vitamin D levels on dental implant integration. The study included 42 patients in 2 groups; with insufficient (Group IN-S; n=21) and sufficient (Group S; n=21) levels of vitamin D. Bone remodelling, proinflammatory and antiinflammatory markers were analyzed in bone and peri-implant crevicular fluid (PICF) using enzyme-linked immunosorbent assay (ELISA) and results were reported as concentration and total amount.
This study will compare 2 methods to clean contaminated implant surfaces: air-polishing device versus titanium curette. Both of these methods will be used in the non-surgical and surgical setting, followed by implant removal. Then, in-vitro analysis to assess the efficacy of surface decontamination will be performed.
This study aimed to investigate the response to non-surgical treatment of peri-implantitis diseases during the maintenance phase. The patients underwent non-surgical implant maintenance treatment, and the success of the treatment was measured again after 30 days using the same criteria and methods.
One critical element regarded to successfully resolve peri-implantitis is to efficiently decontaminate the contaminated implant surface. Mechanical, pharmacological and chemical strategies have been proposed to eliminate bacterial plaque and remnants from the implant surface. However, evidence has not demonstrated superiority of a given detoxification agent/strategy. Recently, the electrolytic approach has been indicated for the surgical detoxification in the management of peri-implantitis. For the electrolytic approach (EA) the implant has to be loaded negatively with a voltage and a maximum current of 600 mA. This is achieved by a device (GS1000, GalvoSurge Dental AG, Widnau, Switzerland) providing the voltage and pumping a sodium formiate solution through a spray-head, which has to be pressed into the implant by finger pressure to achieve an electrical contact. Another critical aspect in the management of peri-implantitis is related to the esthetic sequelae associated with disease resolution. Sanz-Martin et al. in a systematic review demonstrated that reconstructive therapy is less prone to exhibit mucosal recession when compared to resective therapy. Nonetheless, it seems to be unavoidable no matter the surgical intervention. Aiming at attenuating these changes, Schwarz et al. noted that the adjunctive use of connective tissue grafts may enhance the height of the mucosal level, which in turn may impact upon the esthetic outcome. Therefore, the research question is the following: What is the clinical, radiographic and 3D volumetric effectiveness of dermal matrix to improve the outcome of reconstructive therapy of peri-implantitis-related bone defects? The study is to be performed in two centers: Center of Implantology, Oral and Maxillofacial in Badajoz (Spain) and Clinical PerioCentrum Ortiz-Vigon in Bilbao (Spain)
Peri-implantitis is considered a bacteria-mediated inflammatory disease that leads to a progressive loss of support. During the last decade, research has been striving to understand this entity and strategies for primary and secondary prevention of the disease; However, all of them are about the effectiveness of different therapeutic modalities for their management. In general, it was stated that surgical therapy was ineffective in resolving inflammation. Therefore, surgical strategies are usually needed to eradicate the pathology. Taking advantage of the knowledge acquired during approximately a period of time about the surgical treatment of periodontitis, if you propose several alternatives. These are mainly based on the morphology of the defect, although other factors, such as the lack of keratinized mucosa or the habit of smoking can alter the decision-making process. As such, peri-implantitis with angular defects (i.e., defects with infraosseous components) is indicated for reconstructive measurements with no barrier membranes. On the other hand, horizontal defects (i.e., defects with supra-crestal components) are more likely to resolve by resecting therapy with or without bone contouring measures. It is interesting to note that, although early data indicated that the morphology of the peri-implantitis defect often shows a well-contained circumferential defect, it has recently been shown that it often presents a 2/3 wall defect configuration, where the buccal plate is commonly missing bone wall. The reason for this characteristic may recur in the dimension of the basal alveolar bones, insufficient critical buccal bone thickness or implant positioning13 in relation to the bone envelope. In addition, it should be noted that ~ 25% of peri-implantitis diagnosed on a daily basis exhibit a combined configuration of defects (i.e., a combination of infraosseous and supra-critical components). For their reconstructive treatment, many biomaterials have been documented, among them several protocols proposed by our research group. However, the use of biological agents or growth factors has not been investigated for a long time. Platelet Derived Growth Factor (PDGF, Platelet Derived Growth Factor) is one of several Growth Factors or proteins that regulate cell growth and Cellular Division. PDGF plays a significant role, especially for Angiogenesis, which implies the growth of blood vessels from the existing vascular tissue. Uncontrolled angiogenesis is characteristic of cancer. Chemically the PDGF is a Glucoprotein chains A (-AA) or B (-BB) or composed of them (-AB). In the field of periodontics, periodontal regeneration has been shown to be successful in obtaining radiographic bone gain and tissue regeneration.
Despite extensive research on periodontitis, little attention has been given to the symptoms and perception of peri-implant diseases and their impact on oral health-related quality of life. The study aims to assess patient perception of these diseases and their impact on quality of life through a cross-sectional observational study. Patients will be recruited from the Unit of Periodontics at "Le Scotte" University Hospital and will undergo diagnosis followed by questionnaire assessments. No follow-up visits are planned, and validated questionnaires will be administered to evaluate perception and impact on quality of life. Study procedures will include recording biometric peri-implant parameters and administering questionnaires such as the Brief Illness Perception Questionnaire (BIPQ) and Oral Health Impact Profile-14 (OHIP-14).
In 10 systemically healthy non-smokers, free of periodontitis, one newly restored implant (baseline-T0) and one corresponding tooth were followed over 12 months (T1). All implants were screw-retained, and platform-switched. Oral hygiene was closely monitored during the study. Probing pocket depth (PPD), attachment levels (CAL), bleeding and plaque indices and crevicular fluid were collected from an implant-site (PICF) and a tooth-site (GCF). Total proteomic profiles in PICF and GCF were investigated using label-free quantitative proteomics.
The aim of this study is to analyse contiguous dental implants and its peri-implant status depending on different inter-implant distances.
The current trial aim was to evaluate clinically and radiographically the changes around dental implants inserted immediately in maxillary anterior esthetic zone using a novel combination of autogenous demineralized tooth graft. with autogenous demineralized tooth plate and compared this approach to autogenous demineralized tooth graft. The present study included 63 patients, aged 20 to 45, with teeth that needed to be extracted. After Kafrelsheikh University research ethics committee approval, patients were randomized into 3 groups: group I patients underwent immediate implantation with Duo-Teck membrane, while group II patients underwent the same procedure, but the dehisced bone defect was grafted by autogenous demineralized tooth graft. finally group III was grafted by combination of autogenous demineralized tooth graft. with autogenous demineralized tooth plate.
The aim of the study is to assess which prophylaxis methods is the most suitable for peri-implant hygiene between erythritol and ultrasonic scaler with peek inserts. A randomized clinical trial will be conducted on the patient. Patients will be randomly divided into two groups: - Erythritol group: erythritol with a particle size of ~14 µm will be used for 5 seconds (AIRFLOW® PLUS EMS) - Ultrasonic scaler group: a piezoelectric handpiece with peek inserts (Mini Piezon EMS; PI EMS) will be used. Different subgroups will be defined according to the material of the dental crown of the related implant. The oral hygiene session will be carried out every 6 months (2-years follow-up; 6 sessions), after instruction and motivation of the patient, completion of the clinical chart with the recording of the Probing Depth (evaluation in mm of the peri-implant sulcus taken by a periodontal probe; 4 surfaces of the gingival margin are detected: vestibular, palatal/lingual, mesial, distal), Bleeding on Probing and Plaque Index.
