Filter by:The goal of this clinical trial is to assess the efficacy of chitosan as a socket preservation material after tooth extraction in compare to the standard treatment. The study will include patients who exhibit hopeless tooth without any periodontal infection. Smokers, history of allergy, patients with major medical issue and pregnant women will be excluded from the study. The main question[s] to answer is : is there a significant difference in bone density and dimension between the test and control groups after tooth extraction or not. Participants will be asked to do CBCT scan and take upper and lower impressions before extraction and after three month from extraction. Then, the patients will randomly assigned to one from these groups: There will be a total of three groups (10 patients for each), first group will be treated using mixed of chitosan and allograft, second group will be treated using allograft alone and the last group will be used as control. All patients will be treated in accordance with the 2013 Declaration of Helsinki.
This case series aimed to assess the efficacy of a novel horizontal ridge augmentation modality using histomorphometry and Raman spectroscopy. Combinations of "sticky bone" and tenting screws without autologous bone were used as augmentative materials.
Evaluation of the surgical result (augmentation volume, proportion of newly formed bone) after perforation of the bone block in the course of lateral block augmentation prior to planned implant installation.
Comparing amount of horizontal bone gain 4 months after alveolar ridge augmentation using IPRF Nano- micro Sticky Bone with perforated collagen membrane versus occlusive barrier membrane by : 1. clinical and Radiographic analysis . 2. Histomorphometric analysis .
Is the use of collagen membrane on top of particulate bone mixture covered by onlay bone block in Maxilla better than the use of mixture of particulate bone covered by onlay bone block without the use of collagen membrane, in terms of bone quality and bone quantity?
After atraumatic tooth extraction and the assessment of the feasibility of immediate implant placement, patients will be randomly assigned to one of three treatment concepts: 1. Immediate Implant Placement and Immediate Provisionalization 2. Alveolar Ridge Preservation. After 4 months of healing an implant will be placed with simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. 3. Spontaneous Healing of the socket. After 4 months of healing, an implant will be placedwith simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. In all groups, four months after implant placement, a prosthesis will be delivered. From this experimental period onward, patients will be scheduled for maintenance. Clinical, radiographic and volumetric assessment will be performed by clinicians not involved in the surgery and blind with respect to treatment assignment at 1, 3 and 5 years post loading.
- Patients will be diagnosed to determine whether they are eligible for the inclusion criteria of this study or not. Patients who are eligible will start their surgical treatment in the next visit after radiographic and surgical site evaluation. - On the day of surgery, each patient will be assigned to either intervention or control group, the patients will receive inferior alveolar nerve block and long buccal nerve anesthesia. Future implant site will be planned, an incision will be made and flap will be reflected along the defective ridge. - Implant fixture/s will be inserted in the previously planned site. Uncovered fixture threads and bone defect will be covered by MPM or autogenous bone graft. - In the control group, autogenous particulate bone graft will be used for vertical augmentation and covered with titanium reinforced membrane. In the intervention group, MPM (Mineralized plasmatic matrix) will be used. - Edges will be approximated, Sutures will be placed. - Osstell instrument will be used to measure and record fixture primary stability in ISQ units. - Patients will be referred to the fixed prosthodontics department for placement of the crowns after ensuring success of osseointegration and implant stability (after 4 months). - Patients will evaluate their overall satisfaction after fitting the final prosthesis using a questionnaire at 9 months. - After 9 months, CBCT will be performed to evaluate augmented bone height to be compared with the bone height previously recorded in CBCT. - Osstell instrument will be used to evaluate the implant stability ratio in ISQ unit to be compared to the ratio recorded before.
The purpose of this clinical study is to evaluate the safety and the efficacy of BonoFill-II as a bone filler containing the patient's own (autologous) adipose (fat) tissue-derived cells in reconstructing bone in two clinical indications: 1. Bone augmentation (e.g. sinus augmentation) 2. Bone grafting after removal of cysts from jaws
Twenty four patients with bone resorption on the anterior maxilla will be divided into two groups with different kinds of grafting: bone block associated with particulated biomaterial and particulated mixture of autogenous bone and biomaterial stabilized by collagen membrane and pins. The techniques will be compared according to volume gain, quality of graft osseointegration, implant survival and maintenance of the level of soft tissues.
Bone grafting following tooth extraction is commonly performed to preserve bony ridge dimensions adequate to support subsequent implant placement. Alveolar ridge resorption commonly occurs following tooth extraction, and the decrease in bone volume has the potential to make dental implant therapy impossible without surgery to reconstruct the ridge. The aim of ridge preservation grafting is to prevent or minimize this resorptive process, thereby preserving an adequate volume of bone for implant placement. Ridge preservation generally involves placement of a particulate bone graft material in the tooth socket, followed by use of a membrane or similar substance over the socket entrance to contain the bone graft. Various grafting materials have been recommended for these ridge preservation procedures, including demineralized freeze-dried bone allograft (DFDBA). The timing of dental implant placement following ridge preservation procedures is controversial, and few studies have examined the effects of different healing time intervals between ridge preservation and implant placement. The purpose of this project is to evaluate the formation of new bone at a site where tooth extraction has been performed followed by grafting using DFDBA. Two different study groups are included, one having the dental implant placed 8-10 weeks after tooth extraction and ridge grafting, the other having the dental implant placed 18-20 weeks after extraction and grafting.
