View clinical trials related to Alveolar Bone Loss.
Filter by:Two groups of patient with horizontally deficient anterior maxilla indicated for bone augmentation ,one will be subjected to autogenous onlay bone block from retromolar bone and the other to cortical shell from retromolar bone also.
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.
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.
Background- Periodontitis, an inflammatory disease of the periodontium, is one of the major causes of tooth mortality. Of all the bone destruction patterns that are present in periodontitis, horizontal bone loss is the most common. Therefore, treatment modalities that help in rebuilding horizontal defects are vital in total periodontal reconstruction. Rationale- The supracrestal bone regeneration in cases of horizontal bone loss has remained a mirage with very little recorded success. Volume stable collagen matrix(VCMX), is a porous, cross-linked collagen matrix of porcine origin designed to facilitate cell and vascular ingrowth and soft-tissue volume augmentation, may be beneficial in maintaining the supracrestal space and may overcome the limitation of bone regeneration in horizontal defects. Evidence has shown that Low level laser therapy(LLLT) based on principal of biostimulation of osteoclastic cells, can have a positive effect on the regeneration of supracrestal bone in horizontal bone destruction. So, this study will be first of its kind using combination of VCMX with LLLT to assess regenerative outcome in treatment of horizontal bone destruction in patients with periodontitis. Objectives: To assess clinical and radiographic regenerative outcome of periodontal tissues using LLLT and placing VCMX with single flap approach(SFA) in treatment of horizontal bone loss as compared to LLLT and SFA. Method: A total of 60 patients will be randomly divided into three groups: Test Group 1: VCMX +LLLT +SFA, Test Group 2:LLLT+SFA, and Control group: SFA. Periodontal parameters will be evaluated at baseline, 3, 6, and 9 months. CBCT will be evaluated at baseline and 9 months. Expected outcome: VCMX with Laser could achieve supracrestal bone regeneration in horizontal bone loss.
Bone healing is affected by smoking, particularly healing of extraction sockets, showing deficiencies in vertical and horizontal bone dimensions compared to the healing of non-smokers. Several approaches have been made to stimulate. Bone wound healing, including human autologous blood-derived fractions. One of these fractions is the leukocyte platelet-rich fibrin (L-PRF). L-PRF has been evidenced as potentially beneficial in promoting bone defect filling in alveolar bone and socket preservation in non-smokers. However, scarce evidence is related to this beneficial effect in smokers. This clinical trial aims to study and compare the in vivo effects of L-PRF during bone wound healing and regeneration in smokers. The main question is: Has the L-PRF a beneficial effect during alveolar ridge preservation in smokers? After consent, participants with tooth extraction indications and implant rehabilitation treatment will be enrolled. After randomization, participants will be assigned to an experimental group treated with L-PRF plugs and membranes or a control group (physiological healing). Participants will receive two interventions: - First intervention: Tooth extraction, intraoral scan, and Cone Beam Computed Tomography in the treated zone. - Second intervention (4 months after first intervention): intraoral scan and Cone Beam Computed Tomography in the treated zone
