Filter by:The aim of this study is to clinically and radiographically evaluate the dimensional changes of hard tissue after using Partially Demineralized Dentin Block versus Xenograft in the esthetic zone. The main question: In patients with unrestorable teeth, will the use of partially demineralized Dentin Block be more effective than Xenograft in preserving vertical and horizontal ridge dimensions? After enrollment, a thorough preoperative assessment, including history taking, clinical, and radiographic examinations, will be conducted. Initial therapy includes periodontal treatment (phase 1 therapy) followed by random assignment to one of two treatment groups: ridge preservation using Partially Demineralized Dentin Block or Xenograft. Both groups will undergo atraumatic extraction. For the test group, an autogenous partially demineralized dentin graft will be prepared, involving tooth cleaning, grinding, and partial demineralization with the Tooth Transformer device, followed by Leukocyte-Platelet Rich Fibrin (L-PRF) membrane and liquid fibrinogen preparation. The L-PRF membranes will be cut, mixed with dentin particles, and combined with liquid fibrinogen to form a compact graft. The block will be placed inside the socket and covered by an L-PRF membrane and secured with a cross-suture. In the control group, Xenograft will be used, and the socket filled with deproteinized bovine bone mineral, covered with a collagen membrane, and secured with a cross-suture. After a healing period of 6 months, at the time of implant placement, a biopsy will be taken using a trephine bur.
the aim of this study is to establish if there are clinical, radio-graphical and histomorphometrical differences between using Allogenic Demineralized Dentin matrix versus Demineralized Freeze-Dried Bone Allograft (DFDBA) as a clinical application in alveolar bone regeneration procedures related to implant dentistry, including socket preservation, alveolar ridge augmentation, after tooth extraction in the esthetic zone.Will ridge preservation using Allogeneic Dentin Matrix be more effective than Demineralized Freeze-Dried Bone Allograft in managing the post extraction hard tissue alterations? The initial therapy consists of periodontal treatment (phase I therapy) including supragingival scaling, subgingival debridement if needed, adjustment of faulty restoration and polishing. The mechanical plaque control instructions for each patient include brushing and interdental cleaning techniques. alginate impression will be taken to fabricate an acrylic stent to be used as reference for measurements of width of ridge clinically. Flapless and atraumatic tooth extraction will be initiated, Then the socket will be filled either with Allogeneic Dentin Matrix or Demineralized freeze-dried bone allograft (DFDBA) up to the crestal level of then bone followed by placement of a collagen membrane to cover the socket. criss-cross horizontal mattress suturing technique Intervention group: The socket will be filled with Allogeneic Dentin Matrix Control group: The socket will be filled with Demineralized freeze-dried bone allograft (DFDBA). For both groups, All the subjects will be evaluated at pre-surgical, baseline and 6 months post surgical months for clinical parameters and baseline( immediate post-surgical and 6 months post-surgical . Outcomes: Change in ridge width clinically after 6 months, Change in the radiographic buccal vertical bone level, Change in the radiographic palatal vertical bone level,Change in the radiographic horizontal bone level,Percentage of new vital bone formation,Percentage of residual bone graft and Implant Primary Stability.
- The aim is to evaluate post extraction hard tissue changes following ridge preservation using partially demineralized dentin block versus L-PRF block in intact socket in the esthetic zone. - The main question: In patients with un restorable tooth, Will ridge preservation using partially demineralized dentin block be more effective than L-PRF block in managing the post extraction hard tissue alterations? - After enrolment, periodontal and radiographic examination and patients with badly un-restorative tooth in the esthetic zone will be identified. These patients will undergo to mesio-distal distance between adjacent teeth, corono-apical height of bone, presence of labial undercut, dehiscence, or fenestration and Relation to adjacent teeth measurements using trans gingival probing technique, and preapical radiograph or CBCT . - In both groups, the desired tooth will be extracted under local anesthesia using peritomies and surgical forceps. - In intervention group: the teeth will be cleaned and dried, and then the dentin will be ground to obtain particles of a certain size then partially demineralize dentin will obtained by using a tooth transformer machine. At the same time, blood samples are collected and processed to obtain fibrin membranes rich in platelets and leukocytes. This tissue is then mixed with partially demineralized dentin to create a solid mass called a "dentin block". During the process of preserving the alveolar bumps after extraction, this solid mass "dentin mass" is placed inside the dental pockets and covered with fibrin membranes rich in platelets and white blood cells, then 5/0 proline suture are used to fix the fibrin membranes and dentin mass in place. After the recovery period "4-6 months", a biopsy is taken for some cases from the site of the operation for histological evaluation during implant placement. - In control group: the same steps as the first group will be used, but by replacing the partially demineralized dental graft with a xenograft. - Outcomes: Radiographic vertical buccal bone changes, vertical Palatal bone changes, horizontal bone changes, Percentage of new vital bone formation, Percentage of residual bone graft, Implant Primary Stability. The results directly postoperative and 4-6 months postoperatively.
Many dentists, clinicians and researchers have conducted numerous trials, and put several materials and procedures under the test, in an attempt to preserve vertical and/or horizontal extraction sockets dimensions. The clinical consequences of post-extraction remodeling may affect the outcome of the ensuing therapies aimed at restoring the lost dentition, either by limiting the bone availability for ideal implant placement or by compromising the aesthetic result of the prosthetic restorations. In an attempt for ridge/socket preservation of a freshly extracted tooth socket/bed, this study aims to assess and compare between using autogenous tooth graft added with Hyaluronic acid, and the usage of the standardized autogenous tooth graft alone, regarding the potency, preservative feature, and quality of bone healing, density, and deposition. For a better restorative outcome using a delayed implant placement later on in the edentulous area.
The primary objective of the present study is to clinically and radiographically evaluate the efficacy of autogenous tooth graft obtained from bone mill and dental grinder to preserve alveolar ridge dimensions in extraction sockets.
The research is about socket preservation using the ice cream cone technique including collagen membrane and xenograft compared to spontaneous healing.
There is limited data regarding socket preservation in three wall defects and no enough evidence of implant placement in previously regenerated area with allograft. The aim of this randomized controlled clinical trial is to analyze and compare dimensional changes in extractions sites with buccal bone defects > 5 mm left untreated (simultaneous regeneration during implant placement) or treated using a mineralized allograft.
