Filter by: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.
Dental implants have become one of the most common treatments used for the rehabilitation of lost teeth. The success rate of dental implant treatment is quite high. One of the criteria used for long-term implant success is the evaluation of radiographic marginal bone loss. Implants are used at the bone and tissue level in implant treatment. In this study, it was planned to use 20 implants of the same brand, with a single implant in the bilateral posterior regions in 10 patients.The study will be designed as split-mouth. The implant will be placed at the bone level with the same protocol in the two edentulous areas and the flap will be closed primarily. After 3 months, the substructure of the two-piece abutment concept system will be placed in a region during the healing head placement stage, and the bone level implant will be converted to the tissue level. A conventional healing cap will be placed in the other area. Periapical radiographs will be taken from the patients who participated in our study, as in all implant patients, during the pre-surgical planning phase and after implant placement. With the 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. Clinical measurements will be taken in all patients at the prosthetic loading session and 1 year after loading.
For patients having periodontal intrabony lesions, three treatment modalities were executed to evaluate the effect of protecting Leukocyte rich -Platelet Rich Fibrin harvests (applied in the bony defects) with resorbable collagen membranes. Clinical Outcomes recorded were the Plaque index (PI), Gingival index (GI), probing depth reduction (PD), Clinical attachment level (CAL), and radiographic defect depth changes. For the biochemical evaluation: levels of PDGF-BB and VEGF obtained from crevicular fluid by Perio-Paper strips were assessed using ELIZA.
The extent of marginal bone remodeling around the neck of dental implants has been used for many years as a criterion for defining their long-term success. Apico-coronal position represents a crucial factor in this field. This study aims to establish the optimal insertion depth of a subcrestal implant, with the aim of minimizing the bone resorption.
Immediate implant placement has proven to be a successful treatment procedure that is preferred by patients because of being less traumatic, more time-efficient. Nowadays, the main goal of a successful immediate implant treatment has ceased to be gaining stability and osseointegration, but achieving long-term dimensional stability has become the optimal challenge. Various soft tissue and hard tissue augmentation techniques have been investigated in order to maintain the ridge dimensions following extraction and immediate implant placement.
early marginal bone loss around dental implants may hamper long term prognosis of implant-prosthetic rehabilitation. this study aimed to study the correlation of pico-coronal position of dental implant (from supracrestal, crystal to undergone level) measuring early marginal bone loss through periapical x-ray at surgical time and subsequent follow-ups.
The aim of the study is to evaluate the use of erythropoietin gel as an adjunct to xenograft in the surgical management of intrabony periodontal defects.
This study was conducted to clinically and radiographically evaluate locator RTx attachments for two implant-supported mandibular overdenture using two loading protocols
Completely or partially edentulous patients suffer from resorption of the alveolar bone, they always seek rehabilitation which becomes challenging. Alveolar ridge augmentation is widely done now to offer these patients functional and esthetic restoration. Many techniques have been proposed to obtain good results of ridge augmentation. Titanium Mesh (TiMe) is widely used, also digital and computer-guided surgery now plays an important role to improve the techniques and results in ridge augmentation procedures.
The aim of the present investigation will be evaluate the healing of periodontal intraosseous defects following Minimally Invasive Non Surgical Debridement (MINSD) and application of a hyaluronic acid-based gel, compared to MINSD alone. A total of 22 patients will be enrolled, selected by inclusion and exclusion criteria and randomly divided in two groups: hyaluronic acid group (HA) and no-hyaluronic acid group (No-HA).
