Clinical Trial Summary

Clinical Trial Description

Periodontal intrabony defect is a specific osseous defect with definite morphology. Numerous therapeutic modalities for restoring such defects have been investigated. Nanocomposites and nanostructured materials are thought to have a key function in hard tissue research, since natural bone tissue is a distinctive model of a nanocomposite. Collagen has been potentially used in periodontal tissue engineering. The integration of collagen as a structural protein, serving as an essential component of connective tissue into three-dimensional scaffolds implanted after periodontal injury, necrosis or inflammation has attracted much attention in tissue regeneration. If a collagen matrix collapses after implantation, host cell migration and blood vessel penetration may be impaired, which in turn negatively influences tissue degradation and integration as well as extracellular matrix production in the interior of the biomaterial. Thus, volume stability is an important parameter for tissue augmentation. Volume stable collagen matrix (VCMX) is able to overcome the volume stability limitation of most commercially available grafts. It is one of the most biocompatible, novel material to be used in this study. While mechanical stability is achieved by chemical crosslinking, mechanical testing demonstrated preserved elasticity of the material over 14 days. It has shown quite impressive results in resolving the intrabony defects in animal studies with an average of 58.56% of new bone formation . Sustained release of growth factors with preserved biological activity is one of its important properties. It will be the first time that VCMX is to be used to regenerate the periodontal tissues in intrabony defects in humans. MATERIAL AND METHODS: Systemically healthy forty chronic periodontitis (stage II and III periodontitis) patients having 40 intrabony defects will be randomly assigned into test group (intrabony defect filled with VCMX after open flap debridement [OFD+VCMX]) and control group (OFD only). Patients fulfilling the eligibility criteria will be enrolled in the trial after obtaining informed consent. Primary outcome measures include probing pocket depth, clinical attachment level, and percentage bone fill (%BF). All parameters will be recorded at baseline,3,6 and 9 months postsurgical follow-up. This study will be conducted at Department of Periodontics and Oral Implantology, PGIDS, Rohtak, Haryana. It is a Randomized controlled clinical trial which is to be carried out with a follow up period of 9 months. It has been approved by the institutional review board and institutional ethical committee. Parameters recorded for experimental and adjacent teeth will include: PIaque index (PI) and Gingival Index (GI), bleeding on probing (BOP, %), PPD, CAL, and gingival recession (REC). Parameters that will be assessed using CBCT will include defect fill (DF), alveolar crest changes (ACC), and defect resolution (DR). Each patient will receive the initial phase of the therapy, which will include oral hygiene instructions, supragingival and subgingival debridement. Periodontal re-evaluation will be done to confirm the sites that required surgical therapy. A full-thickness mucoperiosteal flap will be raised, no bone recontouring would be performed, Thorough debridement of the surgical site would be performed. For the test group, VCMX would be placed according to the dimensions of the intrabony defect after open flap debridement (OFD). For the control group, OFD will be done and After this, flaps would be approximated and sutured at the original position with a monofilament suture material using interrupted sutures. Periodontal dressing (Coe-Pak, GC) will be used to cover and protect the surgical area. All study participants will be prescribed amoxycillin 500 mg (Mankind Pharmaceuticals) three times daily for 5 days and ibuprofen 400 mg (Abbott India) three times daily for 3 days. Patients will be instructed to rinse twice daily with 0.12% chlorhexidine. Patients will not be advised to use mechanical means of plaque control in the surgical area until sutures were removed. Sutures and periodontal dressing will be removed after a 1-week postoperative interval. Instructions for maintenance of proper oral hygiene will be reinforced. ;
