Filter by:This study consists in a randomized controlled trial which objective is to assess the accuracy of a dynamic navigation system in zygomatic implant placement in partially or total edentulous patients in the upper jaw compared with the conventional freehand method.
The goal of this randomized clinical trial is to compare biting force and patient satisfaction in three groups. Patients in the control group number one will receive a CoCr removable partial denture, and in the other two groups, implants will be inserted to restore missed posterior teeth (second mandibular premolar and second mandibular molar) in the span area. After three months, implants will be loaded with three units of anatomical PFM-fixed partial dentures in group number two, while in group number three, implants will be loaded with three units of anatomical Zirconia-fixed partial dentures. Biting force will be measured bilaterally at the time of delivery of the removable partial denture and delivery of fixed partial dentures after two, four, and six months. Patient satisfaction will be assessed through a quality-of life questionnaire at the six-months recall appointment
The goal of this randomized controlled clinical trial is to compare implant stability between hybrid implants and fully rough implants in partially edentulous patients. The main question it aims to answer is: are hybrid implants able to achieve a sufficient level of secondary stability in comparison to fully etched implants? Participants will receive dental implants and the secondary stability will be measured using resonance frequency analysis (RFA) at the 2-month post-implant placement mark. Implants that do not attain adequate secondary stability will undergo re-evaluation at monthly intervals up to 6 months. Researchers will compare the test group (hybrid implants) or the control group (fully rough implants) to see if they present a comparable secondary stability.
The purpose of the study is to evaluate in novice surgeons the accuracy of the X-Guide® navigation system (X-Guide®, X-Nav Technologies®, Pennsylvania, USA) in implant placement compared to freehand implant placement.
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.
The aim is to clinically evaluate the effect of the alveolar sealing technique using a customised abutment on soft tissue volume changes following molar extraction and immediate dental implant placement.
Emergence profile and crown contour of implant supported rehabilitation, which is influenced by implant position, is associated with peri-implant health and esthetic outcomes. However, there is no study prospectively explore the association between implant position, emergence profile/crown contour, and dental implant outcomes. Thus, the present study aims to (1) assess the multivariate association between local factors and peri-implant soft-tissue health, inflammation, and microbiome; and (2) to identify patterns/clusters of implant characteristics significantly associated with health or inflammation.
The aim of this study will be to evaluate the non-inferiority of implants produced by additive manufacture loaded in 30 days when compared with those loaded in 90 days, in relation to marginal bone loss, after 01 (one) year of follow-up
The DS Prime Taper EV dental implant system was recently launched on the implant market by Dentsply Sirona (York, PA, USA). Dental implant systems are undergoing rapid evolution, ultimately driven by their broad therapeutic indications. As manufacturers strive to keep up with the demands of a growing market, designs are changing faster than clinical evaluation. This means that the time needed to assess medium- and long-term clinical outcomes before designs change again cannot be met. Clinicians need to have a "real" analysis of the clinical performance of implants before using them. Therefore, reporting of results is necessary to avoid use in patients without proper practical checks even before the recommended 10- and 15-year follow-up periods.
This study was designed to assess peri-implant soft tissue health, volume and marginal stability at implants sites which presented small buccal bone dehiscences (<3mm evaluated in a vertical direction) at the time of insertion. Patients will be then randomly allocated to receive grafting with connective tissue graft or volume stable collagen matrix and evaluated at 3 months after surgery and at 12 months of follow up after crown placement.
