Filter by: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
The aim of the comparative study is to evaluate the density and amount of new bone formed (bone height gain)around dental implant placed simultaneously in posterior maxilla after closed sinus floor elevation using Osseodensification burs versus electrical mallet.
The goal of this clinical study is to investigate the effectiveness of the split-box technique in systemically healthy, non-smoking, over 18 years of age, participants with narrow crests (<5mm bone width) and adequate bone height (>12mm). The main questions it aims to answer are: - The primary objective of the present study is to investigate the effectiveness of the split-box technique by evaluating the change in width and height of the alveolar bone. - The secondary objective is to evaluate the superiority of the split-box technique and its modifications in terms of the amount of bone gain. According to the 3D topography of the alveolar ridge of the patients before augmentation, split box or one of its modifications, reverse split box or sliding split box techniques were selected and applied. (split box was applied if the bone thickness was more than 3 mm at the top of the crest and did not increase towards the lower border at the alveolar bone, reverse split box technique was applied if the bone thickness was more than 3 mm at the top of the crest and increased towards the lower border at the alveolar bone, sliding split box was applied if the bone thickness was less than 3 mm at the top of the crest but the bone thickness increases towards the lower border at the alveolar bone.)
the purposse of the study To evaluate the effect of implant supported hybrid prostheses on the bone of the supporting structure of edentulous mandible using Polyetherketoneketone (PEKK) framework versus cobalt chromium framework. fourteen female patients with lower single edentulous ridges are chosen with adequate dental hygiene, enough interarch space and free of systemic diseases and parafunctional habits. Patients who received new single dentures are randomly allocated into each group using computer software program and five intraforaminal implants were inserted parallel using surgical guide.
The loss of a tooth or change in its function is lead to a change in alveolar ridge's height and volume. Socket preservation (SP) is a procedure designed to prevent or limit alteration of the post-extraction bone ridge to achieve an optimal prosthetic implant rehabilitation. The aim of this randomized-controlled clinical trial is to suggest that platelet rich fibrin (PRF) as solely grafting material may be a valid tool in this technique.
The aim of this study is to evaluate the radiographic and the clinical outcomes of application of the alveolar ridge splitting (ARS) in combination with ATG, associated with immediate implant placement versus ARS in combination with autogenous bone graft, associated with immediate implant placement in patients with horizontal bony insufficiency of alveolar ridges.
The goal of this clinical trial is to compare in patients with atrophied anterior maxilla, bone augmentation techniques ( gold standard bone block and tent pole technique). The main question it aims to answer is : Does screw tent pole technique provides better bone gain than autogenous bone block in atrophied anterior maxilla? - primary objective to assess amount of bone gain - secondary objective assess bone quality Participants will be randomly divided into two groups study group ( tent pole technique) and control group ( bone block) - each group will be followed up monthly for soft tissue dehiscence and after 6 month to assess bone gain and bone quality and then implant placement.
Objective: The objective is to evaluate the dimensional changes of soft tissue and alveolar ridge after extraction of posterior elements with different clinical protocols of alveolar preservation.
The design is a single blinded, dual comparative study of ultrasound versus micro-CT/LASCA in one study group. Up to a total of 140 subjects registered will be recruited. Subjects who are treatment planned for extraction of a hopeless tooth and socket augmentation with bone graft and are planned for a dental implant surgery. The socket will be evaluated before the extraction and multi-time points during healing until an implant is placed with various evaluation tools, including ultrasound.
