Filter by:The study was designed as a retrospective, parallel, two years longitudinal pilot trial. Twenty-eight patients (mean age: 48.34 ± 6.06) aged between 35 and 60 years and 66 TiUnite surfaces (Nobel Biocare Parallel Conical Connection), bone level dental implant were included in the study. The implants were divided into two different groups according to the NPIs and regular platform implants(RPIs). The mean implant lengths, plaque index(PI), gingival index(GI), periodontal pocket depth(PD), gingival recession(GR), keratinized gingival width(KGW) and bleeding on probing(BOP) values were recorded. The Student's t-test used for between-group comparison.
This study aimed to evaluate the clinical complications that might be presented with osteotome and densah burs, as well as to assess the new bone generated at 6 months post-operatively using CBCT. The study hypothesis was that densah bur would show comparable results to osteotome-mediated sinus lifting
Studies evaluating the use of customized healing screws/abutments in immediate implant placement have been performed, aiming to assess possible advantages with the use of this treatment modality. Despite the existence of these investigations, there is a lack of information regarding a digital approach to evaluate in an objective manner soft and hard tissue dimensional changes at this treatment modality.
Survival and success rates of all-ceramic implant-supported fixed reconstructions fabricated with CAD/CAM technology after at least one year in function. Survival and success rates (clinical, radiologic and esthetic) of all-ceramic implant-supported fixed reconstructions fabricated with CAD/CAM technology after 2 to 10 years in function. Establishment of a database of patients with all-ceramic implant-supported fixed reconstructions fabricated with CAD/CAM technology for future longitudinal retrospective studies.
The aim of this study was to compare the influence of the abutment height and insertion timing on early marginal bone loss (MBL) in posterior mandibular partial implant-supported restorations. Material and methods: The study was planned as a prospective, randomized, controlled parallel group including subjects in need of two implants for the restoration of an edentulous posterior mandibular area. Data were gathered on age, gender, attached gingiva height, bleeding on probing (BoP), smoking habits and previous periodontitis. The patients were allocated into three groups: Group A implants were immediately connected to 2 mm height abutments; Group B implants were immediately connected to 1 mm height abutments; Group C implants were left to heal in a sub-mucosal position and 2 mm abutments were inserted in a second stage surgery. Peri-apical radiographs were taken at the implant surgery (baseline), 4 weeks after surgery (T1), 16 weeks after implant placement at the final restoration delivery (T2) and 1-year after implant placement (T3).
The aim of this study was to evaluate the early and late implant loss rate in a sample of patients who had received implant-supportive restorative therapy in a university setting. Moreover, the study aimed to identify patient- and implant-related variables for implant failure
The convenience sample to be included in the present study will consist of all individuals who had implants installed at the Dentistry Clinic of the University Santo Amaro, between the years 2004 and 2010. The following criteria will be evaluated: age; sex; presence of systemic disease; area in which the implant was installed; implant diameter and height; type of prosthesis installed; presence of bone resorption and annual maintenance.
In this retrospective study, approximately 60 patients treated with 6mm short implants (Straumann, SLA (sandblasted, large-grit, acid-etched surface), SLActive (sandblasted, large-grit, acid-etched, hydrophilic surface), 4.1 or 4.8 mm in diameter) will be followed for 4.5-18.2 years. Clinical and radiographic parameters will be assessed in a follow-up examination.
This is a randomized, single-blind, split-mouth clinical trial to evaluate the performance of peri-implant tissues (bone and soft tissues) in conventionally loaded Galimplant implants, using a classic multi-position, anti-rotational abutment, comparing it to the new multi-abutment aesthetic slim anti-rotational placed both at the time of the implant surgery. To this end, 80 Galimplant implants with a diameter of 4 mm and 10 mm in length will be placed in areas of mature scarred post-extraction bone. Patients be divided into 2 study groups, group C: straight pillar; Group T: Slim pillar. The bone and clinical radiological stability of the peri-implant tissues will be evaluated at 6 weeks post-surgery and at 6-12 months post-prosthetic loading.
This is a randomized triple-blind clinical trial to evaluate the behavior of peri-implant tissues (bone and soft tissues) in BLX implants loaded early or delayed and with different surgical milling protocols. To this end, 40 BLX implants with a diameter of 3.75x10 will be placed in areas of mature bone scarred after extraction. They will be divided into 2 study groups, and these in turn into two subgroups. Group A: complete milling, Group B: partial milling. Each group will be assigned with code 1: early load and code 2: deferred load. Clinical and radiological parameters will be evaluated.
