Filter by:The observed medical device in this study were SGS P7D Dental implant. The device replaces the lost tooth root, and provides support for the dental bridges and crowns, or overdenture replacements. This medical device provides the opportunity to to replace partial or complete missing teeth. Device material: Ti-6Al-4V Device surface protection: Corundum Blasting and 1. phosphate surface treatment or 2. hydroxylapatite surface treatment
For free hand dental implant placement, a key difficulty is to accurately control the position. Improving precision of dental implant placement is considered important for safety and efficacy of tooth replacement with dental implants. The goal of this randomized controlled trial is to compare the positional implant accuracy, and patient reported outcomes comparing two methods of implant placement: the use of a robotic assisted surgery and freehand surgery. Patients requiring single tooth replacement with a dental implant will be digitally planned using a CBCT and an intraoral digital scan. Subjects will be randomized to one of the two treatment modalities based on the plan. The accuracy of placement will be assessed evaluating the difference between the planned and the actual position using a CBCT immediately after surgery. Subjects will be followed up for one year to assess both patient reported and professional outcomes.
Introduction: the repeated connection and disconnection of healing abutments during dental implants´ osseointegration has been associated with significant increased peri-implant bone loss, when compared with placing the final prosthetic abutment during implant placement surgery and non-removing it ever again. Previous data from animal studies suggests that the higher the number of removals of the healing abutments, the greater the bone resorption around implants, however the evidence in humans is scarce and heterogeneous. Furthermore, this greater bone resorption has been claimed to be associated to the inflammatory status of the peri-implant soft tissues, which would be greater as a consequence of the repeated disruption of the soft-tissues attachment to the prosthetic abutment, and the hypothetical microbial contamination of the implant-abutment interphase, induced by the repeated manipulation of the prosthetic components. Objective: to evaluate the changes in peri-implant crestal bone levels between two prosthetic protocols, the control being the conventional protocol where healing abutments are placed during surgery and removed four times before the delivery of the final abutment and prostheses, and the test protocol where definitive abutments are placed immediately after implant placement and are not removed ever again. Material and methods: 80 platform switched implants will be placed in the posterior maxilla or mandible of 40 partial edentulous patients. Immediately after implant placement, patients will be randomized to receive the definitive abutment at the moment of implant placement (one abutment-one time protocol), or 12 weeks later, after removing the healing abutment four times during the confection of the final prostheses, following the conventional protocol for implant supported restorations. The day of prostheses delivery, a mucosal biopsy from the implant surrounding tissues will be taken for histomorphometric and immunohistochemical analyses of the inflammatory response of the peri-implant soft tissues. Radiographic assessment of vertical bone level changes (primary outcome), clinical status of peri-implant tissues, changes in soft tissues margin, patient related outcomes and adverse events will be assessed at 6, 12, 24 and 36 months after loading.
A dental implant is an alloplastic material surgically inserted in a residual bone ridge, mainly with a prosthetic foundation. Nowadays the most widely used implants and with a higher degree of scientific evidence are the titanium root-form endosseous implants. In addition to the root component, the prosthodontic systems that allow the crown to be connected to the implant are very important. The aim of this project is to compare a classic anti-rotational straight esthetic multi-position attachment with the new anti-rotational straight esthetic slim multi-position abutment, both placed at the time of implant surgery. A multicenter randomized single-blind (for the patient) split-mouth randomized clinical trial will be performed to compare the composition, distribution and structure of the peri-implant tissues around the classic straight (control) and Slim (test) intermediate prosthetic abutments of the manufacturer Galimplant (Sarria; Lugo, Spain). The objective is to study which abutment design obtains a better biological seal from the clinical and histomorphometric point of view. For this purpose, 60 dental implants will be placed for the replacement of bilateral posterior absences in 30 patients attending the Master of Oral Medicine, Oral Surgery and Implantology of the University of Santiago de Compostela, Spain.
This study will compare two commonly used soft tissue grafting techniques (connective tissue graft, CTG vs Acellular Dermal Matrix, ADM) to augment the soft tissue at the time of lateral ridge augmentation procedure. Following ridge augmentation procedure, most of the times there is a need for soft tissue augmentation to change the quality of the tissue around future implant's site. To our knowledge, the influence of soft tissue augmentation at the time of ridge augmentation procedure has not been tested defects.
