Filter by:The loss of a single tooth could negatively impact the physiologic occlusion because of the tipping of neighboring teeth and the super-eruption of the opposing teeth. In addition, it compromises the esthetic, especially when anterior teeth are missing, leading to psychological problems such as loss of confidence and avoidance of smiling in public with a defect in phonetics. Restoration of the missing tooth is achieved in many ways, including removable dental appliances, fixed dental prostheses and dental implants. Implant placement is classified into different protocols according to the time of placement in relation to the time of extraction. These different protocols are immediate implant placement (type 1) on the day of extraction; early implant placement (type 2) after 4-8 weeks with soft tissue healing; early implant placement (type 3) after 12-16 weeks with partial bone healing; and delayed dental implant placement (type 4) after complete bone healing at least 6 months after tooth extraction the Aim of the work: to evaluate facial bone changes after early implant placement protocols clinically and radiographically.
The goal of this clínical trial is to compare in patients needing extraction of anterior teeth the effects of leukocyte-and platelet-rich fibrin (L-PRF) for alveolar ridge preservation versus spontaneous healing. The main questions it aims to answer are: - Does L-PRF use as alveolar ridge preservation material diminish volumetric changes in the alveolar ridge produced after tooth extraction and further bone regeneration needs? - Does it have any advantage for wound healing and patient-related outcomes? Participants will undergo - Tooth extraction - Alveolar ridge preservation/ spontaneous healing - Implant placement Researchers will compare alveolar ridge preservation with L-PRF with spontaneous healing to see if there is an effect on reducing ridge dimensional changes happening after tooth extraction.
The purpose of this study is to compare ridge dimensional changes between densification and standard drilling protocols and to compare primary and secondary stability of implants placed by bone densification and standard drilling protocols
Anthogyr Axiom Tissue-Level implants and corresponding Multi-Unit abutments recently enriched the available product range for dental surgeons. This Post-Market Clinical Follow-Up study aims at confirming the safety and performance of these products. The comparison with similar Anthogyr Axiom Bone-level implants will provide additional information on the effect of platform-switching in bone level maintenance for single and two-piece design at the implant level.
The objective of this randomized and longitudinal clinical study is to compare the installation of immediate implants in the esthetic zone through computer-guided-surgery and conventional surgery. To this end, 22 patients who need implant-supported replacement on the anterior region of the maxilla will be selected and after extraction will receive: Guided surgery (GS): installation of dental implant with the aid of the virtually planned guide by means of specific software; Conventional surgery (CS): installation of dental implant performed freehand using a conventional surgical guide made by study models.
The purpose of this study is to compare the clinical success, radiographical volume maintenance and histological bone regeneration after using either a bovine bone xenograft or an autogenous platelet rich plasma enrich in growth factors, known as Endoret®-PRGF®.
The aim of this pilot study was to assess survival rates and peri-implant bone loss of two narrow-diameter titanium-zirconium implants supporting maxillary and mandibular overdentures during an observation time of 3 years. The masticatory performance, self-reported chewing ability and change of oral health impact profile (OHIP) after rehabilitation were also investigated.
The objective of this prospective, randomized, pilot study is to determine whether the Conelog® connection is suitable for splinted/non-splinted cemented crowns in the chewing centre (focus only on implant-abutment connection) and whether implants with the Conelog® connection and a length of 7mm are suitable for use in the molar region of the lower jaw.
When an implant is placed, it is assumed that there will be a loss of bone in the more coronal area around it. The placement of the implant in relation to bone level, either crestal or subcrestal and the type of connection chosen, either external connection or internal connection, have been related as one of the factors that caused this loss. The preservation of the peri-implant bone influences the shape and contour of the underlying soft tissues, which are important for the aesthetic result of the treatment and for the success of the same. Hypothesis: The hypothesis is that there are no differences between the external and internal connection with regard to marginal bone loss. In implants placed at the crestal and subcrestal level, the hypothesis is that there is greater marginal bone loss in implants placed at the subcrestal level. Objectives: Main: To evaluate the marginal bone loss around implants of internal connection and external connection. Secondary: To compare the loss of bone in implants of internal connection placed at crestal and subcrestal level. To evaluate intra and post-operative complications. Material and methods: A prospective and randomized radiological study will be performed. 150 implants will be placed in patients who must present partial edentulism and require the replacement of at least 2 crowns on implants in the same jaw. In a randomized manner, implants of external connection and internal connection will be placed. Other features such as surface treatment type of the implant will be similar in both types of implants to reduce bias. With this study the investigators will try to define if there is a procedure in when to the connection of the implant and the location of this, that is more beneficial with respect to the preservation of bone.
The aim of the present study is to test whether there is a difference in the marginal bone level change between implants with and without cantilevers.
