Filter by:It is necessary to evaluate the outcome of implant supported fixed prosthetic rehabilitations using peek material. To test this, the study design to be used will be a prospective single cohort to evaluate the long term outcome of fixed prosthetic implant supported rehabilitations. The cohort will be evaluated after 5 years of follow-up, regarding prosthetic survival, implant survival, marginal bone resorption, incidence of mechanical complications (loosening or fracture of prosthetic components), biological complications (peri-implant pathology, suppuration, fistulae), incidence of biological complications (peri-implant pathology, suppuration, excessive marginal bone resorption) in-mouth comfort, overall chewing feeling, framework integrity, veneer adhesion, veneer chipping, patient tissue reaction, denture staining, manufacture issues,
Introduction: Single-stage dental implant placement protocol involves the placement of healing abutments. In addition to osseointegration process, healing of peri-implant soft tissues is of a great importance too. Routinely, healing abutments made of titanium (Ti) are used. The aim is to find novel materials that would have the same mechanical properties, but less prone to plaque-adhesion and therefore showing lower local inflammatory soft tissue response. Polyetheretherketone (PEEK) is a thermoplastic polymer that has favorable mechanical characteristics, high biocompatibility and low submissiveness to microorganism adhesion. White color makes it aesthetically acceptable in the treatment of patients with thin gingival phenotype. The Aim: To compare the formation of dental plaque on PEEK and Ti healing abutments and examine the local response of peri-implant tissues. Materials and Methods: The study included 11 patients with at least two missing teeth in the posterior regions. In each patient, 2 implants were installed, with PEEK abutment (experimental group) placed on one implant, while on the other implant, Ti abutment (control group) was placed. Before prosthetic rehabilitation of patients, both abutments were replaced with new ones and a thin layer of peri-implant soft tissue was sent to histological analysis. Results: The average age of patients was 49 years. Out of 11 patients, 27% were female and 73% male. 36% of respondents were smokers. Histological immunohistochemical analysis of samples of peri-implant soft tissues showed massive inflammatory infiltration in subepithelial tissue in the experimental group (10/11), while the inflammatory infiltrate in the control group was classified as moderate (7/11) or weak (4/11). Conclusion: Both types of healing abutments have been shown to be successful in single-stage implantation protocol. However, contrary to expectations and preliminary findings from the literature, PEEK healing abutments showed a more pronounced inflammatory response of the surrounding soft tissues relative to Titanium abutments.
In this non-interventional study (NIS) a polyamide non-absorbable suture (Dafilon) will be evaluated for oral surgery (mucosal closure after e.g. wisdom teeth extraction, implant surgery, etc.) in adult patients
The aim of the present study was to evaluate the accuracy of a prefabricated digitally planned provisional restoration on a single- implant placed with a fully guided surgical protocol.
The aim of this study is to evaluate and compare two prosthetic conditioning techniques to create natural-like peri-implant emergence profile.
This research aims to evaluate the effect of anodic oxidation of implant abutment collar on the peri-implant soft tissue health.
This study compares the peri-implant soft tissue and crestal bone loss around single implants when placed macrosurgically and microsurgically.
Diabetes Mellitus (DM) is a recognized factor affecting implant complication rates, including peri-implantitis and peri-implant bone loss, and the apico-coronal position of implants seems interfere on the conditions of peri-implant tissues. However, the influence of the vertical implant position in type 2 diabetics (T2DM) is unclear. This split-mouth randomized controlled trial evaluated the impact of implants of machined-collar placed at crestal level or supracrestally in T2DM rehabilitated with implant-retained overdentures on the clinical, tomographic and immunoinflammatory peri-implant outcomes after implant loading.
This is a prospective, adaptive, parallel study with four arms, which seeks to compare the accuracy of freehand and guided dental implantation surgeries. The basis of the comparison in each case is a digital plan, and that digital plan is compared to the actual postoperative status by computerized, three dimensional analysis.
This study is designed as a retrospective, multi-center study. The study population consist of subjects who received one or more OsseoSpeed EV implants during the period January 1st 2015 to December 31st 2016. Two hundred subjects will be enrolled, approximately 25-30 subjects per site. The study includes retrospective data collection from subjects' medical records and data collection from one prospective study visit with a clinical examination.
