Filter by:Aim of the current study is to evaluate clinically and radiographically transcrestal sinus lifting with densah burs with the use of activated plasma albumin gel associated with simultaneous implant placement.
Background- Periodontitis, an inflammatory disease of the periodontium, is one of the major causes of tooth mortality. Of all the bone destruction patterns that are present in periodontitis, horizontal bone loss is the most common. Therefore, treatment modalities that help in rebuilding horizontal defects are vital in total periodontal reconstruction. Rationale- The supracrestal bone regeneration in cases of horizontal bone loss has remained a mirage with very little recorded success. Volume stable collagen matrix(VCMX), is a porous, cross-linked collagen matrix of porcine origin designed to facilitate cell and vascular ingrowth and soft-tissue volume augmentation, may be beneficial in maintaining the supracrestal space and may overcome the limitation of bone regeneration in horizontal defects. Evidence has shown that Low level laser therapy(LLLT) based on principal of biostimulation of osteoclastic cells, can have a positive effect on the regeneration of supracrestal bone in horizontal bone destruction. So, this study will be first of its kind using combination of VCMX with LLLT to assess regenerative outcome in treatment of horizontal bone destruction in patients with periodontitis. Objectives: To assess clinical and radiographic regenerative outcome of periodontal tissues using LLLT and placing VCMX with single flap approach(SFA) in treatment of horizontal bone loss as compared to LLLT and SFA. Method: A total of 60 patients will be randomly divided into three groups: Test Group 1: VCMX +LLLT +SFA, Test Group 2:LLLT+SFA, and Control group: SFA. Periodontal parameters will be evaluated at baseline, 3, 6, and 9 months. CBCT will be evaluated at baseline and 9 months. Expected outcome: VCMX with Laser could achieve supracrestal bone regeneration in horizontal bone loss.
Utilization of collagen vs PRF membrane over the graft following sinus lift procedure and before suturing
To compare the diagnostic accuracy of extra-oral x-rays with intra-oral x-rays, in contrast to clinically observed measurements, for the detection of calculus and bone loss of either the suprabony or infrabony types in patients undergoing periodontal surgery.
The primary aim of the present study is to compare the Sub-periosteal Peri-implant Augmented Layer (SPAL) technique and soft tissue augmentation (STA), performed simultaneously to implant placement, in terms of (i) implant survival rate and (ii) health/disease condition of the peri-implant tissues at 6 and 12 months following implant loading. The secondary aim of the project will be to compare the SPAL technique and STA in terms of intra- and post-operative morbidity. The study is designed as a single-blind, parallel-arm, randomized clinical trial. Patients will be recruited and treated at the Operative Unit of Dentistry, Azienda Unità€ Sanitaria Locale (A.U.S.L.) of Ferrara, Italy, and one University center (Research Centre for the Study of Periodontal and Peri-implant Diseases, University of Ferrara, Italy). Each patient will contribute the study with one sextant ("experimental sextant"). Each eligible patient will be randomly assigned to receive SPAL technique or STA according to a computer-generated randomization list. Surgical procedures will be performed by experienced periodontal and implant surgeons. Two calibrated, blinded examiners will take care of the assessment of clinical and radiographic parameters, Case Report Form (CRF) filling, as well as data extraction from CRFs for the preparation of the study database. The proportion of patients free from peri-implantitis at 12 months following loading will be the primary outcome variable of the study. The proportion of patients with complete resolution of the bone dehiscence (BD), dimensional variations and 12-months characteristics of BD, and patient-reported outcome measures will be the secondary outcomes. The design will test two hypotheses, with a non-inferiority trial in terms of primary outcome and a superiority trial in terms of secondary outcomes.
The purpose of the study is to determine the efficacy and safety of the effects of a topical medication on bone remodeling after dental extraction, in order to establish whether such treatment can be a new therapeutic option for said pathology. The participation of 60 patients is expected, who will be divided randomly in equal proportions into two groups. Treatment groups: Group A (30 patients): medication administered topically. Group B (30 patients): placebo with characteristics equal to the drug under investigation.
Alveolar bone resorption often occurs after tooth extraction. At present, guided bone regeneration technique is widely used in clinic since it leads to less trauma and less complications. Tenting screw technology, basic on the classical GBR, implants screws into the surgical area to prevent the barrier membrane from collapsing. Moreover, advanced platelet rich fibrin and injectable platelet-rich fibrin are used to provide the osteogenic function. The investigators intend to increase vertical alveolar bone augmentation by combining tenting screws and A-PRF, I-PRF.
Tooth autotransplantation is a treatment option to replace tooth with imposible prognosis. In several cases the receipt site has a reduced bone dimension. This situation may be imposible the treatment with dental implants without bone reconstruction. Autotransplantation seem to improve the anatomic characteristic of the receipt site without any reconstruction approach. The aim of this study is to evaluate the bone dimension changes followed autotransplantation treatment.
Comparative study for evaluation of vertical bone gain after one stage ridge augmentation with advanced platelet rich fibrin (A-PRF) and xenograft versus guided bone regeneration using collagen membrane and xenograft.
This study designed as a randomized controlled split-mouth trial will be conducted at the Dental Clinic of the University of Valencia. The aim will be to assess differences in clinical, radiological and microbiological outcomes between implants with 2 different connections: internal hexagon and conical connection. Following the premises, to minimize the bias related to prosthetic phase and maximize the effect of connections on MBL changes, a 1abutment-1time protocol will be used. The study hypothesis is that there will be no statistically significant differences between both implant connections.
