Filter by:The aim of this trial is to compare the effect of autogenous demineralized dentin graft combined with injectable PRF loaded with metronidazole (sticky demineralized tooth releasing metronidazole) versus autogenous demineralized dentin graft combined with injectable PRF (sticky demineralized tooth) versus autogenous demineralized dentin graft (ADDG) alone on alveolar ridge preservation after extraction of non restorable, infected single-rooted teeth
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.
The goal of this clinical trial is to compare implant stability, and crestal bone loss, when using minimal invasive ridge splitting versus convenient open flap technique. The main question is Does Minimal Invasive Implant ridge splitting ("transmucosal" without flap) influence the implant stability and crystal bone loss, when compared with the conventional open flap techniques? Researchers will compare Group A: Minimal Invasive Implant ridge splitting and Group B: Triangular flap technique is used to see if there is significant difference between the two groups when measuring implant stability, and crestal bone density.
To evaluate the clinical effect of site preservation after third molars extraction by using tooth extraction of third molars with site preservation using bio-oss and bio-guide in preventing the formation of deep periodontal pockets in the distal of second molars.
The aim of the current study is to compare the effect socket sealing with flowable resin composite compared to dense polytetrafluoroethylene membrane after filling the extraction site with xenograft particles in terms of soft and hard tissue changes, procedural time, post operative pain, patients' satisfaction, and cost effectiveness.
The purpose of this study was to report the clinical and radiographical outcomes of using autogenous cortical bone plates combined with sticky allogenic bone graft for augmenting maxillary anterior atrophic combined horizontal and vertical ridge defects with simultaneous versus staged implant placement.
Guided Bone Regeneration (GBR) is an invaluable and beneficial surgical technique adopted when there is the need to augment an alveolar atrophy. Strong clinical and histologic evidence exists on the effectiveness and predictability of GBR in bone augmentation of ridge deficiencies. On the other hand, it is well known that GBR remains a challenge as in the most extreme cases, it is considered a highly technique-sensitive surgical procedure. Whilst there are numerous reviews which report the average incidence of complications in GBR, there is still insufficient evidence and manuscripts reporting a direct correlation between a specific biomaterial (membrane or scaffold) and observed complications. Only one recent systematic review and meta-analysis focused on wound healing complications following GBR for ridge augmentation procedures. Authors explored the complication rate based on the membrane type and on the timing of the first sign of soft tissue complications following bone augmentation procedures. They reported a complication rate of 17% of the overall soft tissue complications, including membrane exposure, soft tissue dehiscence, and acute infection (abscess). This estimate is consistent with that reported (12%) in a more recent systematic appraisal of the evidence on all types of complications in GBR (3). However, when horizontal augmentation procedures were reviewed, a higher rate (21%) of complications was reported within the first 18 months of a GBR procedure. This estimate was inclusive of all possible biologic complications following GBR whilst the rate of membrane exposure was of 23%. Vertical bone augmentation represents one of the most challenging bone regenerative procedures in surgical dentistry. This is because of the inherent difficulties of the surgical procedure and the high risk of complications. The primary aim of this procedure is to recreate alveolar bone in a vertical direction (without the support of any pre-existing walls) and enable recreation of a more favourable anatomy for the restoration of the edentulous site. Evidence on a variety of treatment options has been produced over the last 15 years including distraction osteogenesis, onlay bone grafting, and vertical ridge augmentation (VRA). Systematic reviews evaluating the efficacy of different surgical procedures for VRA either in a staged or a simultaneous fashion, reported a range of vertical bone gain of 2-8 mm. This gain was gradually lost (1.27 to 2.0mm) between 1 to 7 years post-surgery and a wide range of complications (0- 45.5%) has been reported. The aim of this study is to assess and compare incidence of complications and percentage of vertical bone gain when using four different barrier membranes in combination with 50/50 autogenous and xenogenous bone material in VRA procedures. Secondary aims will be to evaluate and compare early and late soft tissue wound healing, gingival microvasculature and structure, patient reported outcomes and the prevalence of need for further bone augmentation and need for soft tissue grafting. Additionally, this study will also aim to assess and compare histomorphometry and histochemistry analyses of core biopsies obtained before implant placement between the four different barrier membranes.
The goal of this clinical trial is comparing the efficacy of custom-made zirconia sheet versus Polytetrafluoroethylene as a non-resorbable barrier in maxillary alveolar ridge augmentation. The main question it aims to answer are: 1. Is custom made zirconia sheets are valuable as a non-resorbable membrane in guided bone regeneration? 2. Does it have any adverse effects on the surrounding tissue? 3. the accuracy of using two software in the designing of the zircon membrane? - Participants will be selected according to the inclusion criteria of the study, having a defect in the upper jaw that prevent rehabilitation of the jaw. - Participant will undergo a surgical procedure for placement of bone graft and the non-resorbable membrane. Researchers will compare between two groups which differ only in the used membrane. a group where the researchers will place custom made zirconia sheet versus a group where the researchers will place Polytetrafluoroethylene.
The aim of study is evaluation of accuracy of completely versus partially limiting computer generated surgical three-dimensional guides during placement of zygoma implants in patients with atrophic maxillae.
In patients with missed lower posterior teeth and resorbed lower jaw, the study aimed at restoring the jaw's height and width to accommodate placing dental implants. The study was designed as a clinical trial with two arms; control group and study group. In the control group, titanium-reinforced polytetrafluoroethylene (Ti PTFE) membrane was used to secure the grafted bone mixture in the recipient site. While in the study group, bone-plate technique (Khoury technique) for bone restoration was used to secure the grafted bone mixture as well. The donor bone was the lower jaw (for bone particles and bone-plate harvesting) and bovine bone particles mixed together to form the graft mixture. Patients were monitored for six months and assessed by X-rays. The outcome variables were volume and height of gained bone in cubic millimeters and millimeters, respectively.
