Filter by:This study aims to compare the clinical outcome before and after augmentation in case series of 10 patients. The main question it aims to answer is Whether the semi-rigid shell system facilitates bone regeneration in moderate to severe alveolar bone defects after 4 months of bone augmentation. Participants with bone defects between 3 to 8 millimeters (moderate to severe bone defect) will be treated with xenograft covered with the semi-rigid shell barrier system as a stage approach technique for implant placement.
The aim of this randomized controlled trial is to evaluate the tridimensional bone stability after horizontal one-stage GBR using collagene membrane (OssMem) with a mix of Bovine Bone Substitute (A-Oss) and autogenous bone (test group) versus A-Oss and LCR-A, a synthetic bone (control group).
To address the gap of knowledge in comparing between the bone augmentation outcomes with or without tacks for membrane stabilization
clinical study with guided bone regeneration for deficient alveolar ridge to restore the defect in width and be able to place implant with two different technique
Dental implants have been on the market for several years and they are routinely used to replace single/multiple missing teeth with a high success rate. However, there is still a limited number of studies comparing hydrophilic titanium and zirconia implants. In addition, there is no data available on the signalling pathways and the expression of healing biomarkers involved in the early stages of osseointegration around zirconia surface implants placed with guided bone regeneration (GBR). This study aims 1) to describe and compare the early wound healing molecular pathways, and the 2) vascularization patterns of mucosal tissues after the placement of hydrophilic titanium or zirconia implants with simultaneous guided bone regeneration (GBR). In this study, the investigators will assess the expression of inflammatory, angiogenesis and osseous biomarkers of PICF at 3, 7, 15 and 30 days after the placement of hydrophilic titanium or zirconia dental implants with simultaneous GBR and of saliva at day 1, 3, 7, 15 and 30.
The most frequent aesthetic complication following single implant treatment seems to be a lack of buccal convexity. This 'alveolar process deficiency' is the result of buccal bone remodeling following tooth extraction. A traditional approach to treat alveolar process deficiency is guided bone regeneration (GBR), however post-operative complications such as swelling, bleeding and pain are common and the aesthetic outcome may not be optimal. An alternative to the traditional GBR approach could be soft tissue contour augmentation using a connective tissue graft (CTG) at the buccal aspect. Possible advantages over GBR include less morbidity at the implant site, a superior aesthetic outcome since there is no need for vertical releasing incisions and less costs since there are no biomaterials to be used. The primary study objective is to compare the GBR and CTG group in terms of 2 and 3 dimensional tissue alterations, focusing on the amount of tissue gain and volume stability over time. The secondary study objectives are morbidity, overall radiographic, clinical and aesthetic outcomes.
Immediate tooth replacement with immediate implants into fresh extraction sockets has become a common and promising clinical procedure in daily practice in regard of implant survival, osseointegration and esthetic outcomes . However, there are some challenges encountered in the treatment of patients with labial bone plate dehiscence. Deficiency of facial bone anatomy has a negative impact on esthetics and is a critical causative factor for esthetic implant complications and failures .. Few studies investigated the reconstitution of labial bone plate dehiscence using ice cream cone technique and their results showed adequate bone regeneration 4 to 6 months where no labial plate was present prior to grafting technique. Ice cream cone technique as a flapless grafting technique in conjunction with immediate implant placement in patients with labial bone plate dehiscence requires further studies for its clinical relevance and approval.
This is a Phase 1 study to evaluate the safety profile of autologous-derived SB cells to enhance osseointegration of GBR in patients undergoing dental implant surgery.
Guided bone regeneration (GBR) is a surgical technique that uses barrier membranes to promote osteoblast cells proliferation and exclude other cells such as epithelium and connective tissue cells. GBR is often combined with bone grafting procedures. Using Absorbable membranes like collagen membrane will reduce treatment time by decreasing need for second surgery
The main target of the study is to compare ultra-narrow diameter implants (2.75 mm) without bone regeneration versus standard diameter implants (4.3 mm) in combination with bone regeneration. To do so, patients with missing upper central incisors, canines, first or second premolars with alveolar ridges of 6 - 8 mm of thickness will be restored with dental implants. Cone beam computed tomographic examination and clinical values will be registered before and after the surgical procedure at 6 and 12 months.
