Active clinical trials for "Jaw, Edentulous, Partially"

A total of 34 participants, who require replacement of an anterior or posterior single tooth with dental implant, will be randomly allocated to two equal sized groups. In the control group, the osteotomy site preparation will be prepared by using conventional surgical drills, while the test group site preparation will involve the use of Densah™ Burs (Versah Co., LLC., USA) as per the osseodensification protocol. In addition to evaluating implant stability, the trial will also report on implant and patient outcomes at various time points.

Dental implants may suffer from bone loss around them, particularly at the upper portion where the prosthesis starts. The connection between both parts of the tooth restoration is key for avoiding micromovement during chewing, bacterial contamination and initiation of bone loss. Thus, investigating factors related to this bone loss in different types of implant-prosthetic connections is key for promoting better use of available therapeutics devices. In this study, we will study marginal bone levels over time as well as bacterial contamination and inflammatory markers in the peri-implant sulcus around implants with connical connection and compare them with those obtained when using implants with internal hexagonal connection. The hypothesis is that bone loss will be higher in implants with hexagonal connection associated with a pathological microbiome in the sulcus that induces a higher inflammatory response.

The microthreaded and platform switched implants could control the stress in the suitable range. The splint would disturb the function. So it is necessary to know whether the splinted single-unit crowns is fit for the adjacent multi-implants. Outcome variables: Splinted single-unit crowns on one side implants and non-splinted single-unit crowns on the other side Materials and method: 80-100 consecutive implants in at least 20 patients would be included for implant- supported restorations in the posterior maxilla or mandibular. All patients would be in general good health. For every patient, the same posterior teeth had lost on both sides for more than 6 months. All patients were treated by the same qualified surgeon. Prosthetics procedure would be performed by an experienced prosthodontist. The two sides were allocated to the test or the control group according to the predefined computer-generated randomization table. Clinical evaluations and radiographic analysis were performed by an oral and maxillofacial radiologist who was not aware of the type of Prosthetics technique that was used.

In dental implant restoration, available literature demonstrates the advantage of using tall abutments, with a change of diameter with respect to the implant and a conical internal connection in the abutment-implant gap. However, for multiple restorations, the abutment-prosthesis connection has not been studied in detail. The "multi-unit" systems, both standard and brand specific, have either a flat or butt joint or an cone. In any case, both are external connection systems. Recently, an internal-type abutment-prosthesis connection system has been developed. Although it is proving its usefulness in single restorations, its use in multiple restorations compared to traditional systems has not been studied. Therefore, taking into account all of the above, the present study has the overall objective of analyzing marginal bone loss (MBL) and adaptation of soft tissues by comparing a multiple prosthesis system of the "external, flat" type versus an external system of the "internal, conical" type.

The aim of is to compare the survival rate and technical outcomes of cantilever implant-supported fixed denture prosthetics (cFDPs) made either out of monolithic zirconia bonded to a titanium base in a digital workflow, or porcelain fused-to metal using a gold abutment in a conventional workflow. In addition, biological outcomes, wear patterns, PROMs and time efficiency will be recorded. The null hypothesis is: the reconstruction type does not influence the survival rate and technical outcomes of 2-unit implant-supported cFDP.

The aim of this prospective cohort study is to compare the esthetic, clinical and patient-centered outcomes following immediate and delayed implant placement protocols.

The purpose of this study is to evaluate the outcome of prosthetic survival of the Acuris conometric concept 1 year after permanent restoration, since this is a new mode of retention using friction for seating the crown of single tooth restorations without using cement or screws.

The purpose of this study is to evaluate the clinical outcome of implant survival of the PrimeTaper EV implant in single tooth restorations 1 year after permanent restoration.

The aim of this study is to prospectively collect clinical data to confirm the safety and clinical performance of Neodent Titanium Base Abutment and Pro PEEK Abutment in daily dental practice setting, by means of a randomized clinical study of prosthetic rehabilitation using these devices. A total of 48 healed implant sites (at least 4 months post-extraction) shall be included during the sample enrollment (24 patients), which will be randomly divided into two groups, so that each patient receives one implant from each group (removal and non-removal of the abutment placed at the time of surgery). Patients will be followed for 24 months after implant loading. It is expected that there is no difference in peri-implant bone level change between the two treatment groups.

The aim of this prospective study was to evaluate the soft and hard tissue changes of immediate implant placement with buccal bone augmentation in sites with thin labial bone wall in the anterior maxillary zone.
