Filter by: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.
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 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.
This prospective cohort study aims to investigate the relationship between mandibular canal trajectory and the duration of postoperative paresthesia in patients undergoing inferior alveolar nerve lateralization. The study will assess mandibular canal trajectory using anatomic factors and evaluate nerve sensory function using subjective and objective tests. Implant success criteria will also be assessed. The study will be conducted on patients who underwent IANL due to mandibular atrophy and were unable to receive standard or short implant placement. Data will be collected at regular follow-up visits up to 1-year post-surgery.
Patients with long span, narrow edentulous ridge in the posterior mandible underwent piezotomed ridge splitting and osseodensification with simultaneous implant placement.
The goal of this clinical trial to test the effect of periimplant soft tissue phenotype in the participants with implant placed and at least 1 year after implant loading. The main questions it aims to answer are: 1. Is keratinized mucosal thickness (KMT) important in early marginal bone loss and peri implant health? 2. Is keratinized gingival width (KGW) important in early marginal bone loss and and peri implant health? The researchers plan to include 80 implants in the study. These 80 implants will be divided into 2 groups in 2 different ways according to their KMT and KGW on their buccal surfaces: KMT ≥2 mm are included in the adequate KMT, and those with KMT<2 mm are in the insufficient KMT group. Those with KGW≥2 mm are adequate KGW, those with KGW<2 mm are adequate KGW. The researchers will assess marginal bone loss around the implant using radiographs and collect peri-implant crevicular fluid (PICF) using paper strips. Another researchers will measure the Receptor Activator Of Nuclear Factor-Kappa B Ligand (RANKL), Osteoprotegerin (OPG), Tumor Necrosis Factor Alpha (TNF-α), MicroRNA-223 (MiRNA-223), MicroRNA-27a (MiRNA-27a) levels in the collected PICF. They will compare radiographic bone loss and biomarker levels in groups.
The goal of this split-mouth clinical trial is to evaluate the effects of Manuka honey applied into periodontal pockets after initial periodontal therapy (NSPT) in the treatment of stage 3 periodontitis. The main question it aims to answer is: • does the adjunct of Manuka honey improve the outcome of the non-surgical periodontal treatment. The intervention in this study was conducted in a split-mouth design, meaning that after completing the NSPT for each subject, Manuka honey was administered as an adjunct to the periodontal treatment in two randomly selected quadrants of the oral cavity around the teeth with a specially designed cannula. This was followed by oral hygiene instructions and training. The home-performed oral hygiene procedures were focused on interdental cleaning using dental floss and toothbrushing with regular fluoride-containing toothpaste. The subjects were also instructed not to use any form of oral antiseptic (e.g., chlorhexidine) or antibiotic during the follow-up period.
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.
One of the criteria used for long-term implant success is the evaluation of radiographic bone loss. It is known that the keratinized mucosa over the alveolar crest forms a protective barrier against inflammatory infiltration. In addition, it has been reported that the vertical mucosal thickness on the crest is important in the formation of the biological width around the implant. The aim of this study was to evaluate the effect of vertical mucosal thickness on the alveolar crest on peri-implant marginal bone loss around crestal and subcrestal placed platform-switching implants. In this study, patients will be divided into 2 main groups with vertical mucosal thickness of 2 mm and less and more than 2 mm, and both groups will consist of 2 subgroups as crestally and subcrestally according to the implant level placed. A total of 80 implants will be included, 20 implants in each group. Before starting the surgery, after anesthesia is given, the width of the patient's peri-implant keratinized mucosa and the vertical mucosal thickness over the alveolar crest will be measured. Clinical and radiological measurements will be made in all patients during the prosthetic loading session (T0), at 3rd month (T1), 6th month (T2) and 1 year after loading (T3). With standardized control periapical radiographs to be taken as a result of one-year follow-up, the marginal bone loss amount in the implants will be evaluated using soft-ware.
