Filter by:The aim of this study was to characterize the host-related response of peri-implant soft tissue induced by 3 different materials: titanium, resin and PEEK (polyetheretherketone) on man. The primary endpoint is to asses the histological data available: Histological analyses are carried out with immunohistology (CD68, CD3, CD20, macrophages), non decalcified histology to appreciate the structure of the peri implant soft tissues (Sulcus depth, junctional epithelium, connective tissue adhesion). Moreover: scanning electronic microscope (SEM) of the experimental abutment is performed to juge the cell adhesion on the abutment surface. The secondary endpoint is to assess clinical data, radiological bone remodeling regarding the different material. The hypothesis is that resin abutment lead to more inflammation than PEEK or titanium.
40 patients are included in the study, 20 patients in group 1 (=closure with composite material shaper; test group) and 20 patients in group 2 (=closure with custom-made zirconia oxide abutment; control group). Randomisation envelopes will be used for randomisation. Device under study: Straumann BLX, Roxolid® , SLActive® dental implants with a diameter of 3.5, 3.75, 4, 4.5 mm are used. Allogenic bone botiss maxgraft® cortical granules are used as graft material. Inclusion criteria: 1. Males and females at least 18 years of age or older. 2. One implant per patient. 3. Prior to any study-related activity, the subject must voluntarily sign informed consent, be willing and able to attend scheduled follow-up visits, and agree to the collection and analysis of pseudonymised data. 4. Lateral individual teeth (premolars and molars). 5. Class I extraction socket (intact buccal wall) or class II (1/3 of buccal wall). 6. The gingival contour of the tooth to be extracted - without recession. 7. Adjacent anterior teeth have no periodontal loss. 8. There are no implants in the adjacent teeth. 9. Non-traumatic tooth extraction, which results in intact walls of the socket. Exclusion criteria: 1. Deep occlusion (severe, class II). 2. The patient smokes a lot (more than 10 cigarettes per day). 3. Systemic disease (osteoporosis). 4. No initial stability has been achieved after the implant insertion procedure.
One of the challenges of current implantology involves the preservation or reduction of existing bone resorption, mainly in the buccal bone plate, after tooth loss, which becomes of special importance in the anterior region of the maxilla (aesthetic region). The study evaluates the macroscopic shape of neck implant influence in the results of immediate implants, in a population comprised of individuals from the clinic of the Faculty of Dental Medicine of the University of Porto in need of replacement of a single tooth. It is intended to evaluate the morphometric (direct measures and plaster models measurements), imaging, and photographic characteristics of the V3 implant in comparison with the C1 implant of Mis® by an evaluation period of 6 months when placing an immediate implant.
The aim of this randomized clinical trial is to evaluate the clinical performance through prosthodontic, periodontal and radiographic evaluation of single screw-retained implant-supported restorations fabricated by intraoral scanning of healing abutment with scan peg in comparison to scan body
A post-market, multi-centre, prospective, open, randomized-controlled, non-inferiority clinical study to compare short-term performance and safety of the Straumann PURE 2-piece Ceramic Implant with Straumann Bone Level Implant using a fully digital workflow.
Rehabilitation of edentulous spaces with dental implants has become a routine treatment option as implants enjoy high survival rates over time. Accompanying this increase in implant use, epidemiological studies have also reported escalating incidences of peri-implant diseases. A recent meta-analysis reported that peri-implant mucositis and peri-implantitis had high estimated weighted mean prevalences of 43% and 22% respectively. It is common knowledge that gingivitis is the precursor of periodontitis. Similarly, peri-implant mucositis too precedes peri-implantitis, which is a very challenging condition to treat. Therefore, it is strongly recommended that peri-implant mucositis is managed effectively and in a timely manner. In order to reduce the inflammatory burden within the periodontium, mechanical plaque removal is of utmost importance. Mechanical debridement alone, without any adjunctive aids e.g. chlorhexidine, was found to be effective in preventing per-implant mucositis in short-term clinical trials but did not always result in complete resolution of inflammation (Heitz-Mayfield, et al. 2011, Schwarz, et al. 2015). Therefore, it can be speculated that patient administered home care may play a role in eliminating soft tissue inflammation over time. The study aims to investigate and compare the efficacy of the barrel shaped and tapered interdental brushes in reduction of soft tissue inflammation through removal of interproximal plaque at both tooth and implant sites in patients with moderately rough surface tissue level or bone level dental implants, which were restored with single screw or cement retained crowns and in function for the past 2- 5 years. The hypothesis of the study is that The barrel shaped interdental brush can remove more supra- and sub-gingival plaque and thus have more reduction in soft tissue inflammation, compared to the tapered interdental brush.
In this prospective case series study, 20 patients with an implant-borne single crown following early implant placement with simultaneous contour augmentation will be followed for 10 years. Clinical, radiologic, and esthetic parameters will be assessed. In addition, cone beam computed tomography (CBCT) will be used at 10 years to examine the facial bone wall and compared to the 6 year data.
