Filter by:The aim of the present prospective study was to investigate after a 2-year of follow-up any influence of the surgical technique, manual or digitally guided, on peri-implant marginal bone levels stability in implants placed 1 mm sub-crestally. Patients were treated by means of platform-switched implants provided with a 5 degrees internal conical connection and supporting single screw-retained fixed crowns. Marginal bone level (MBL) measured at prosthesis installation (t0) at 1 (t1), 2 (t2) and at 3 years of follow-up visit (t3) were considered. MBL change from t0 to t3 was investigated. The distance between the implant neck and the first radiographically detected bone to implant contact was considered to evaluate the bone loss. Two groups were considered: Test Group (GD) for implant sites treated with a digitally guided surgery procedure. Control Group (FH) for implants surgically placed without digitally guided surgery, respectively. All the procedures were performed by an experienced operator. Additionally, for both groups MBL changes were correlated to different supra-crestal soft tissue height (STH) amounts: less than 3 and ≥ 3 millimeters, respectively. Peri-implant soft tissue parameters such as probing depth (PPD), modified Sulcus Bleeding Index (mBI) and modified Plaque Index (mPI), were assessed for all the restorations included.
The biggest challenge of oral rehabilitation is the replacement of lost structures and the restoration of their function and esthetics, focusing on matching a healthy tooth. Traditional complete dentures, implant (retained, supported) overdentures, and complete implant-supported fixed prostheses are all alternatives to the rehabilitation of the mandibular arch. The aim of this study was to compare BioHPP used as a skeletal substructure for hybrid (implant fixed, detachable) prostheses versus BioHPP bar supporting and retaining by using radiographic tracing to the marginal bone height changes around the implants, patient satisfaction can be improved.
The impact of smoking on dental implant failure has been a constant topic of discussion for the past decade and the current literature confronts the inconclusive evidence of tobacco for a marginal bone loss risk factor. The aim of the present investigation is to determine the association between tobacco and marginal bone loss or implant failure in a sample of patients who had received implant-supported restorative therapy in the Dentistry Hospital of the University of Barcelona (Campus of Bellvitge). Considering that peri-implant marginal bone is essential for dental implant success, in this study we would like to establish the relationship between marginal bone loss around implants and smoking, in our own population study, in order to improve the prognosis of implant success in smoking patients. On the other hand, knowing the negative effect tobacco has on marginal bone loss in dental implants, we will be able to better predict peri-implant bone loss and reveal the probability of implant failure in short and long-term in smokers. By informing the patient correctly, we can raise awareness and create an additional reason for them to stop smoking, or at least reduce the number of cigarettes they smoke per day.
The aim of the study is to evaluate in patients with history of periodontitis the clinical, microbiological and radiological outcomes of implants with a modified implant design consisting on a machined surface in the coronal third of the implant. In this 12-month, parallel-arm, randomized controlled trial, patients with history of treated periodontitis and in need of dental implants for single-unit or short edentulous spaces (i.e. two implants) will be randomly assigned to a test group (implants with a hybrid surface, presenting a machined coronal third; HS) or a control group (conventional moderately rough implants; RS). Implants will be restored 3 months later with fixed implant supported reconstructions. Radiological, clinical, microbiological and patient-related outcome measures (PROMs) will be assessed 3, 6 and 12 months after the prosthetic installation.
The goal is to evaluate, after 5 to 8 years, the marginal bone loss around tissue-level implants and bone-level implants in patients who have not followed the maintenance program. Medical records of patients who have been implanted for at least 5 to 8 years and who have been lost during this period are collected from three private clinics in Beirut,Lebanon and the Saint Joseph University Health Center in Beirut,Lebanon. On an individual sheet, the patient as well as the implants data will be noted. Patients will be called for reevaluation after 5-8 years. After signing the informed consent, the measurements by a PCP-15 probe of the plaque index (FMPS) and the bleeding index (FMBS) as well as the height of the keratinized tissue are indicated on the sheet. If the smoking status has changed, this will be mentioned too. The marginal bone loss will be measured on the X-rays taken immediately after the implant placement, after 1 year of loading and then at the reevaluation session.
This clinical report describes a technique for ridge splitting, and gradual expansion in the maxilla with simultaneous implant placement with in the split ridge, with the preservation of the thin buccal plate of bone for proper blood supply.
Assessment the need for sinus floor elevation when restoring atrophic posterior maxilla or it will be enough to use of short implant
Assess the long term stability of short dental implants in comparison to standard implants inserted simultaneously with inferior alveolar nerve lateralization.
