Filter by:The purpose of this study is to assess changes in peri-implant tissues and the effectiveness of a tissue-level surgical technique. This technique will be compared with a bone-level surgical technique. This is a post-marketing clinical investigation conducted in the Endodontics Department of the Dental Clinic at the University of Bologna. Patient recruitment and study conduction will follow the principles of the Declaration of Helsinki and adhere to major international guidelines (CONSORT). Implants will be placed using either a bone-level or tissue-level surgical technique, corresponding to implants positioned at the level of the gingival mucosa or submerged implants, respectively. Randomization (1:1 ratio) will be conducted before surgery to create two treatment groups. The experimental group (Tissue Level) (n=40) consists of implants that will be placed with the exposed neck (Tissue-level surgical technique). The control group (n=40) comprises implants placed at the bone level (Bone-level surgical technique). The surgeon will be aware of patient assignment during the implant insertion procedures. The surgical procedure to uncover the implant neck (control group) will be performed 3 months after implant placement. The experimental group (Tissue Level technique) will not require a surgical intervention. he following parameters will be assessed at 1, 6, 12, and 36 months after implant placement: Peri-implant parameters: Plaque score, Bleeding on Probing (BoP), and Papilla Index Radiographic parameters: Marginal Bone Level (MBL) Patient-Reported Outcome Measure (PROM): Post-operative pain (VAS) in the experimental group (non-submerged surgical technique) and the control group (submerged surgical technique).
The purpose of this study is to demonstrate the effect of bioceramic implants on the repair of human bone defects, and to explore the application of bioceramic materials in bone defects, bone implantation, and bone fusion. The surface microstructure of β-tricalcium phosphate bioceramic implants can be effectively controlled to guide the regeneration of bones, promote the restoration of bones, accelerate the speed of recovery, and improve bone quality, which is of great clinical and social significance.
purpose: The primary purpose of this retrospective radiographic study were conducted to compare between milled bar and round bar for mini implant retained overdentures (IODs) on peri-implant bone changes and posterior mandibular ridge resorption .Study Design: A convenience sample of 18 completely edentulous participants were selected for this retrospective study from patients originally available at the start of the trial . The null hypothesis was that there were no significant difference between milled in and round bar attachment retained implant supported overdentures in posterior ridge resorption and peri-implant bone changes.
the study aims to investigate the clinical influence of different implant locations; lateral incisor, canine, and first premolar areas; supporting 2-implant retained mandibular over-dentures with locator attachment on prosthesis retention and peri-implant health.
The loss of a single tooth could negatively impact the physiologic occlusion because of the tipping of neighboring teeth and the super-eruption of the opposing teeth. In addition, it compromises the esthetic, especially when anterior teeth are missing, leading to psychological problems such as loss of confidence and avoidance of smiling in public with a defect in phonetics. Restoration of the missing tooth is achieved in many ways, including removable dental appliances, fixed dental prostheses and dental implants. Implant placement is classified into different protocols according to the time of placement in relation to the time of extraction. These different protocols are immediate implant placement (type 1) on the day of extraction; early implant placement (type 2) after 4-8 weeks with soft tissue healing; early implant placement (type 3) after 12-16 weeks with partial bone healing; and delayed dental implant placement (type 4) after complete bone healing at least 6 months after tooth extraction the Aim of the work: to evaluate facial bone changes after early implant placement protocols clinically and radiographically.
This clinical study aims to evaluate the effect of using PEKK (Pekkton) framework in mandibular implant-supported complete fixed dental prostheses with All-on-four treatment concept on peri-implant tissues health
The goal of this pilot study is to investigate the effect of an evidence-based adherence promoting intervention on exercise adherence of patients with osteoporosis. For this reason, a randomized controlled pilot trial with an intervention period of three months will be conducted. Question I: To which extent does an adherence-promoting intervention (AERO) have an effect on adherence to long-term exercise programs in patients with osteoporosis compared to conventional standard care with home-based exercise therapy? Objective II: Does the AERO Intervention influence fall risk factors such as functional lower extremity strength and fear of falling compared to conventional standard care plus home-based exercise therapy in patients with osteoporosis? Patients will be randomized to two groups: an intervention and a control group. Both groups will receive instructions for a home exercise program (HEP) during six physical therapy (PT) sessions. The intervention group will receive a HEP and additionally the so-called AERO (Adherence for Exercise Rehabilitation in Older people) intervention within 6 PT-Sessions. The AERO program is a feasible intervention for boosting the exercise adherence of older people. The AERO intervention is an evidence-based adherence promoting intervention approach to help patients adhere to an exercise program. The control group will receive six PT sessions as "standard care". In regular clinical practice in Germany "standard care" for people with osteoporosis include measures such as home exercise programs, mobilisations, soft tissue techniques, or training with gym equipment. This will be delivered based on each PT clinical reasoning with no additional motivation for adherence to the exercise program.
Through long-term dynamic monitoring of gynecologic malignant tumor patients undergoing early menopause after ovaries resection in our center, we explored the changes in menopausal symptoms and bone health status of this population, and studied the effects of platinum combined chemotherapy drugs on menopausal symptoms and bone loss in gynecologic malignant tumor patients. To find the optimal time point and effective regimen for MHT in gynecologic malignancies undergoing surgical menopause, and to provide guidance for osteoporosis screening and prevention strategies in women with gynecologic cancer.
Purpose: The aim of this study was to investigate the influence of surface characteristics and geometric design on marginal bone loss and bone quality in dental implants. Materials and Methods: A total of 378 implants from 114 patients were evaluated in this study using panoramic and periapical radiographs. Implants were categorized into 19 subgroups according to the jaw where they were placed, length, diameter, surface preparation, type of prosthetic superstructure, and neck design. Radiological evaluations were conducted based on radiographs obtained at the time of implant placement and 3 months after prosthetic loading. After obtaining measurements of marginal bone loss and fractal analysis data, the significance of differences between groups was statistically evaluated.
Nutrients important to bones. Because bones undergo continuous remodeling, an adequate supply of nutrient substrate is needed to support the formation phase of bone remodeling. In addition to their passive roles as substrate for bone formation, dietary calcium and protein play active roles in bone metabolism, as well as phosphorus and vitamin D. Other vitamins and minerals are also needed for metabolic processes related to bone, directly or indirectly.
