Evaluation the influence of the use of silane coupling agent application as a separate step versus application of silane or acid resistance silane containing adhesives on the clinical performance of repaired posterior resin composite restorations according to Modified United States Public Health Service (USPHS) criteria over one year.
This study compare between the vestibular socket therapy (VST) and the traditional mucoperiosteal flap reflection in immediate implant placement in type II extraction socket in the esthetic zone. The technique of vestibular socket therapy (VST), introduced by Elaskry, enables the placement of implants immediately while simultaneously rehabilitating the entire socket, resulting in excellent esthetic and functional outcomes that meet the expectations of patients. VST involves socket augmentation through a minimally invasive vestibular access incision, eliminating the need for the traditional mucoperiosteal flap reflection, regardless of the extent of socket compromise.
The study will be conducted on 30 patients with split mouth design patients will be divided into curcumin and PRF groups patients will have bilateral tooth extraction one side will receive curcumin/PRF and the other side will be control soft tissue healing and bone quality will be evaluated post-operative
Bone resorption after a tooth extraction is a generally accepted knowledge and has been demonstrated by many animal and human studies. Especially during the first three months followed by the tooth extraction, the volume of bone may change significantly without any interference. Thus, doing a ridge preservation procedure following the extraction is a common standard of care method to maintain the socket volume if implant placement is considered as a treatment option in the future. A variety of materials and methods have been used for ridge preservation. However, it's still inconclusive to determine the best material to maintain the ridge dimension, especially for membrane placement that allows for space maintenance to protect the grafting material. Furthermore, there is no evidence to show any treatment rationale is superior to any other ridge preservation method. In general, the membrane serves the function of the barrier and space protector. The periodontal surgeon use membranes to exclude the epithelium growth and to limit the collapse of the soft tissue into the healing alveolar socket. Regarding resorbable and non-resorbable membrane materials, both serve the function of protecting the graft material from the oral cavity. However, there are also many demonstrating that without membranes the extraction socket healed nicely without any interferences. The question to us is: Do we need the membrane to exclude the epithelium or any kind of surgical dressing material is sufficient enough to preserve the volume of the extracted ridge? The object of this study is to compare five popular membranes on the market that present different characteristics of the membranes.
The aim is to clinically evaluate the changes that occur in teeth that have undergone surgical extrusion treatment. Three parameters will be recorded before and 6 months after treatment: the position and the volume of the soft tissue, and the level of periodontal attachment.
Implant-supported restorations have become one of the best treatment options for patients with tooth loss, with predictable long-term success rates and clinical outcomes. Immediate implant placement means the implant is placed immediately after tooth extraction. It can significantly reduce treatment time because extraction socket healing and implant osseointegration occur simultaneously. Immediate implant placement has many benefits, reducing the overall treatment time, reducing the patient's surgical procedures, and reducing surgical trauma (no flap reversal). However, the treatment also has significant limitations, including the inability to predict the possibility of bone and soft tissue healing, and the possibility of subsequent unfavorable esthetic outcomes. However, the evidence regarding soft and hard tissue and aesthetic outcomes in patients treated with immediate implants in the aesthetic area remains inconclusive. As the aesthetic success of implant restorations is increasingly valued over implant survival, there are significant clinical benefits to addressing immediate implant bone tissue resorption and soft tissue deficiencies and improving the aesthetic outcome of immediate implant restorations. To address the potential health and aesthetic problems associated with soft and hard tissue deficiencies around dental implants, bone grafting in the jumping gap and soft tissue grafting procedures are often performed. According to literature, autologous soft tissue grafts have shown the best clinical and histological results in soft tissue regeneration techniques. However, it requires removal of tissue from the patient's donor area, which can add additional trauma. In contrast, gelatin sponges, currently commonly used as wound closure materials, are only hemostatic and rapidly absorbed postoperatively, and do not provide protection of hard and soft tissue augmentation. Collagen matrix has recently been introduced for keratinized gingival augmentation and has shown encouraging results in preclinical and clinical studies, but more information is needed to confirm its clinical efficacy. Mucograft® Seal is a porcine collagen matrix with a bilayer structure, a dense and slowly absorbing layer and a spongy layer that stabilizes blood clots and allows soft tissue cells to penetrate. Human gingival fibroblasts cultured on Mucograft® were demonstrated to have good proliferative properties and cell viability as scaffold material. In dog extraction sites, preliminary results suggest that the combination of Mucograft® and Bio-Oss Collagen may be an effective method for alveolar ridge preservation. Mucograft® Seal can be used in combination with Bio-Oss Collagen® for alveolar ridge preservation after tooth extraction. The research hypothesis is that the use of a collagen matrix to seal the wound in immediate implant placement in aesthetic area will reduce buccal bone resorption and increase the width and thickness of the soft tissue at the implant site. Therefore, we designed this comparative clinical trial in which patients accept immediate implant placement in aesthetic area. The implant is placed after tooth extraction, and bone graft material Bio-Oss Collagen® is placed in the jump gap, and the wound was closed by different means (collagen matrix or gelatin sponge randomly). The clinical examination, CBCT imaging and histological evaluations were performed to compare the differences in clinical efficacy of the two wound closure methods. The primary outcome is the buccal bone thickness change at the immediate implant site 4 months after surgery.
To evaluate a novel technique of bone regeneration and simultaneous implant placement in severely damaged sockets.
A total of 124 samples was calculated to be sufficient with G*power software ver 3.1.9.2 with effect size of 0.4 alpha probability error and power 0.95.With drop out estimate of 10% the final sample size decided was 140 samples. Patients reporting with complicated(pulp exposed or pulpally involved) horizontal crown root fracture with loss of crown structure in maxillary incisors and radiograph evidence of supra alveolar tooth structure are recruited for study. Informed consent from the patients or guardian as appropriate is obtained as suitable prior to treatment delivery. Exclusion criteria were:patients not willing for recall visits, root with evidence of cervical resorption or roor canal filling, open apices, patient with systemic ailments rendering root canal treatment, compromised periodontal health, vertical or horizontal root fracture. Pulpal condition of tooth was assessed using cold sensibility test(Neosnow, orikam health care Ltd, India.) amd confirmed upon access opening with teeth showing evidence of pulpal bleeding wad categorized as irreversible pulpitis and teeth with no evidence of pulpal bleeding categorized as necrotic pulp.
This investigation will be a clinical trial to study the performance of a newly developed high strength ceramic material for crowns. The ceramic has been approved by the FDA for patient treatment. A computer technique will be used to fabricate the crowns in a single appointment without the need for a temporary crown or second appointment. Two adhesive resin cement techniques will be used to hold the crown to the tooth and they will be evaluated for creating sensitivity to the tooth. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.
