Filter by:After jaw resection, free vascularized bone flaps are frequently used for repairing maxillofacial defects. Simultaneous dental implantation is more preferable to secondary implantation as it saves the patients from going through a second surgery after recovering from the first one. In this study, the aim is to preliminarily evaluate the clinical outcome of simultaneous dental implants in vascularized bone flaps in jaw reconstruction using patient-specific surgical plates and 3-in-1-PSSG. The objectives of this study were: 1) to investigate the intraoperative success rate; 2) to measure the accuracy of dental implants position; and 3) to assess implant survival rate and postoperative adverse events.
The aim of the present study is to compare the rate of new bone formation after sinus floor elevation with or without perforation of the cortical sinus floor prior to insertion of augmentation material. Twelve patients requiring bilateral sinus floor elevation will be recruited for a pilot study in split-mouth design. On both sides a lateral window will be prepared and the sinus mucosa will be elevated. After this step, the sides are assigned as test or control side. While the control side is just filled with augmentation material, an additional step is performed for the test side, i.e., prior to inserting the augmentation material, the cortical bone layer of the sinus floor is perforated several times into the trabecular bone layer to improve the blood supply to the grafting material. Thereafter, both sides are left to healing for 4-6 months until implant installation. At timepoint of implant installation, a bone biopsy will be collected to allow histological assessment of the grafted area.
Post-extraction implants are an alternative to traditional implant placement on completely healed bone, in order to reduce the number of surgical interventions, shorten treatment time, maintain bone architecture and thus provide better aesthetics. This study focuses on evaluating the results obtained by opting for different immediate placement of single dental implants protocols in a fresh alveolus, and its general objective is to compare implant stability and marginal bone loss (MBL) in implants installed post-extraction. For this, the investigators will placement Grand Morse Acqua or NeoPoros implants (Helix GM - Neodent, Curitiba, Brazil), in early loading protocols, with or without low level laser photobiomodulation (LLLT), in patients attending the Master of Oral Medicine, Oral Surgery and Implantology of the University of Santiago de Compostela for oral rehabilitation using osseointegrated single dental implants in the maxillary and/or mandibular region.
A multicenter prospective observational study aims to illustrate the clinical outcome of dental implants "Kontact MB" and the effects of its Mono Block design on the peri implant bone tissue recession and soft tissue conservation. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.
The current research aims at evaluating the outcomes of the vestibular socket therapy in immediate implants using collagen plug, demineralized freeze-dried bone allograft, and deproteinized bovine bone minerals at both radiographic and clinical levels
This study will compare two techniques to achieve increase in ridge dimensions as a preparation for dental implants using a resorbable barrier membrane and bone particulate allogenic graft hydrated with saline or a growth factor called Recombinant Human Platelet-Derived Growth Factor (rhPDGF).
The aim is to comparatively evaluate the soft tissue volume changes that occur after tooth extraction and immediate dental implant placement using two different surgical techniques. These techniques are: the Socket-Shield technique and conventional immediate placement. The null hypothesis is that the Socket-Shield technique better maintains soft tissue volume after partial tooth extraction and immediate implant placement compared to the conventional technique. From a sample of 20 patients, they will be divided into groups of 10 and will be randomized using the random.org program. The soft tissue volume will be digitally recorded by intraoral scanning before tooth extraction and 6 months later. The soft tissue dimensional changes produced will be digitally evaluated and statistically analyzed.
After atraumatic tooth extraction and the assessment of the feasibility of immediate implant placement, patients will be randomly assigned to one of three treatment concepts: 1. Immediate Implant Placement and Immediate Provisionalization 2. Alveolar Ridge Preservation. After 4 months of healing an implant will be placed with simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. 3. Spontaneous Healing of the socket. After 4 months of healing, an implant will be placedwith simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. In all groups, four months after implant placement, a prosthesis will be delivered. From this experimental period onward, patients will be scheduled for maintenance. Clinical, radiographic and volumetric assessment will be performed by clinicians not involved in the surgery and blind with respect to treatment assignment at 1, 3 and 5 years post loading.
This study consists in a double-blinded randomized controlled trial which objective is to assess the effect of the implant-abutment connection type -external hexagon, internal hexagon and conical connection- in the periimplant marginal bone loss in vertical side and the bacterial leakage 12 months after prosthesis placement.
The objective of the research project will be to compare immediate and early unitary implants for the rehabilitation of missing teeth in the upper aesthetic region. A randomized controlled trial will be conducted in parallel with 120 individuals (60 per group) who are above 18 years of age, periodontally healthy, and who need to perform only one unit implant in the upper aesthetic region between the second premolars. In the immediate implant group, the tooth will be extracted in a minimally traumatic manner and the implant will be installed immediately after the fresh alveolus. Bovine bone replacement will be inserted into the gap between implant and vestibular wall of the alveolus, and an immediate temporary will be installed immediately. The provisional will be maintained for 3 months when the definitive crown will be made. In the early implant group, the tooth will be extracted, and after 2 months the implant will be installed with the use of bovine bone substitute to restore the buccal bone contour. The implant will be submerged, and 3 months of osseointegration will be performed reopening and final crown making. In both groups, the individuals will be followed for 1 year after the installation of the definitive crown. The outcomes evaluated will be patient satisfaction (main outcome), gingival phenotype, visible plaque, depth of probing, submucosal bleeding, proximal radiographic bone level, tomographic vestibular bone volume, perimplant clinical aesthetic indexes (Esthetic Pink Score and Papillary Index), evaluation three-dimensional tissue from intra-oral scanning and 3D printing, implant-related quality of life, and early and late implantation failures. Linear and logistic models of generalized estimating equations that take into account the longitudinal character of the study will be used for data analysis.
