evaluation of the use of collagen membrane inside the socket and outside it during immediate implant placement
NCT06863051
The objective of this study will be to compare between Immediate Implant grafted with xenograft and Alb-PRF gel versus xenograft with L-PRF.
NCT05880771
This project consists of placing dental implants at extraction sites. Bone drilling and implant placement are performed using the flapless method with the use of a surgical guide allowing guided surgery. After implant placement, temporary teeth are immediately made and placed on the implants to guide the gingival contour. Bone and soft tissue retraction at the implanted sites are measured radiographically and digitally using surface scan superimposition over a 12-month period.
NCT05670067
In the study immediate implant is placed in the anterior region with autogenous bone grafting from the maxillary tuberosity in one group and in the other group immediate implant is placed with xenograft .IN both groups soft tissue grafting is done using connective tissue assessment of buccal bone thickness and soft tissue will be done 6 months post operative
NCT06728696
Tooth extraction not only alters the bony architecture of the alveolar ridge, but it also has an impact on the surrounding soft tissues. Post-extraction recovery of both hard and soft tissues occurs uneventfully, resulting in horizontal and vertical tissue loss, affecting prosthetic rehabilitation with dental implants or tooth-supported prosthesis. Aim of the study: The aim of this study is to evaluate volumetric soft tissue alterations as well as clinical, radiographic, and esthetic outcomes in dual zone technique (DZ) using CTG (Connective Tissue Graft) versus CGF (Concentrated Growth Factor) Graft following maxillary IIP (Immediate Implant Placement) in the esthetic zone. Materials and methods: 20 patients with hopeless teeth requiring extraction in maxillary esthetic zone and requiring replacement with dental implants, will be enrolled and recruited from the outpatient clinic, faculty of dentistry, Ain Shams University according to the inclusion criteria. They will be randomly allocated into two equal groups. Group I (n=17) immediate implant placement with dual zone technique using concentrated growth factor graft and group II (n=17) immediate implant placement with dual zone technique using connective tissue graft. Pink esthetic score (PES) was measured 6 months after the final crown placement. At the respective times radiographic CBCT measurements, volumetric analysis, and clinical measurements will be taken. Postoperative medication will be prescribed to the patient and postoperative instructions will be explained in detail. Follow-up will be performed. Data collected will be tabulated and statistically analyzed.
NCT06659081
The goal of this clinical trial is to Evaluate of the soft tissue profile changes and labial plate of bone in the anterior esthetic area when using socket shield technique in conjunction with immediate implant and subepithelial connective tissue graft, in comparison to using immediate implant combined by subepithelial connective tissue graft. The main questions it aims to answer is : * does the socket shield technique better preserve gingival contours and connective tissues, resulting in improved esthetic outcomes? * Researchers will compare socket shield combined with immediate implant placement and a subepithelial connective tissue graft to immediate implant placement with just a subepithelial connective tissue graft to see if more favorable soft tissue profile changes and better preservation of the labial plate of bone are obtained. participants will : . subjected to partially extracted socket with immediately placed implant and subepithelial connective tissue graft. .subjected to immediate implant with subepithelial connective tissue graft.
NCT05990283
Among the individuals who applied to the Department of Periodontology, Faculty of Dentistry, Health Sciences University between 2019 and 2021, patients with an unrestorable tooth in the maxillary esthetic region and required implant placement were included in this randomized clinical trial. Before implant surgery, patients were randomized into socket shield technique and guided bone regeneration groups. While the buccal gap was untreated in the socket shield group, a xenograft, and membrane were applied in the regeneration group. Peri-implant pocket depth, modified plaque index, modified bleeding index, keratinized mucosa width, and mucosal thickness were recorded at the permanent restoration and the postoperative first year. Horizontal bone level and vertical bone level were assessed with cone beam computed tomography images taken before the surgery and one year after prosthesis insertion. The pink esthetic score was evaluated with intraoral photographs taken before the surgical procedure and first-year follow-up.
NCT04795102
Immediate implant placement into fresh extraction sockets is gaining popularity because of fewer clinical procedures and maintenance of bone architecture compared to conventional methods, thus reducing the treatment time and increasing patient satisfaction. In addition, the survival rate of the immediate implantation is comparable to that of the healed implantation sites. Recently, ATBG made from compromised teeth was applied in bone defects and resulted in a good clinical efficacy. Moreover, it is more accepted by patients to use extracted teeth as a bone graft material, especially in the case of immediate implant placement. In 2020, Kizildağ and coworkers studied the outcome of PRF as an adjunct with ATBG on bone healing in rabbit peri-implant osseous defects. They reported that combination of ATBG with PRF contributed to significantly higher new bone formation and better bone/implant contact in rabbits with peri-implant bone defects. The main hypothesis behind this study is that using L-PRF with ATBG following immediate implant placement could promote stabilization of graft particles and enhance new bone formation with a shorter time. Therefore, the purpose of this study was to compare the clinical and radiographic outcomes of ATBG on bone formation with or without L-PRF around immediately placed dental implants in periodontally compromised teeth.

It is well known that following the loss of a single tooth, severe hard- and soft-tissue alterations may take place within the affected site, resulting in a subsequent reduction of both vertical and horizontal ridge dimensions, often not allowing neither appropiate pontic fabrication nor correct placement of endosseous implants. Over the past 20 years, various surgical procedures, grouped under the term of "alveolar ridge preservation" (ARP), have been introduced, aiming to maintain the existing soft and hard tissue envelope as well as a stable ridge volume, simplifying subsequent treatment procedures and optimizing functional and esthetic outcomes. They have been widely tested in controlled and not controlled clinical studies with various materials and approaches, and a number of recently published systematic reviews on this topic have confirmed the efficacy of ARP in preventing post-extraction dimensional changes of alveolar ridges. After these procedures a minimum of four to six months must be awaited before implant insertion can be performed, bringing the patient compromised comfort, function and aesthetics and needing of a second surgical procedure for the implant placement. Dental implant insertion at the time of tooth extraction (type I or immediate placement) reduced the number of dental appointments, of surgeries required and the overall treatment time. Nevertheless this surgical protocol does not provide predictable outcomes, since it may contribute towards a more pronounced bone resorption during healing. Different anatomical factors, as the thickness of the buccal bone wall and the dimension of the horizontal gap, may influence the dimensional changes of the alveolar crest following immediate implant placement. Such morphological changes could lead to negative esthetic complications, such as marginal soft tissues recessions, especially when affecting the buccal side of maxillary sites in patients with a high smile line. It is unknown if immediate implant placement plus grafting materials and/or barrier membranes could influence post-extraction dimensional changes of alveolar ridges. No consensus exists on the need for bone augmentation simultaneously with immediate implant placement. Furthermore, no human study has yet compared dimensional changes of both hard and soft tissues after two different treatments: an alveolar ridge preservation technique for a subsequent implant placement, and an alveolar ridge preservation technique with an immediate implant placement.
