Filter by:Mid-facial recession following immediate implant placement (IIP) in the place of a tooth poses a significant challenge for clinicians to treat. Emerging evidence shows that connective tissue graft (CTG) augmentation may mitigate the remodeling of the buccal bone crest (i.e., bone within the gum that supports the tooth), and lessen the soft tissue recession. A recent systemic review suggested a supplemental CTG grafting to IIP as a standard of care, especially for cases that have a high esthetic risk, specifically with a thin gingival biotype (i.e., thin gum tissue) and a thin buccal bone plate. The alternative option to augment the facial contour is the xenogeneic volume-stable collagen matrix (VCMX), which favors avoiding morbidity but hasn't been thoroughly investigated on IIP. Despite that IIP has attracted considerable scientific interest, the dynamic changes of the bone crest and soft tissue, especially during the early healing stage (<3 months following IIP), are little known. Recently, an ultrasonography protocol has been validated for its diagnostic value in dental implant research. High-frequency B-mode imaging and color flow and power Doppler are implemented to display the spatial relation of anatomic landmarks of peri-implant tissues and to visualize the flow velocity and blood volume, respectively. It provides a valuable real-time diagnostic tool to evaluate hard and soft tissue remodeling and tissue perfusion changes during the early healing stage around IIP, comparing CTG and VCMX grafting. Hence, the purpose of this three-arm RCT is to compare the clinical efficacy and longitudinal remodeling of hard and soft tissue around IIP among CTG, VCMX, and control (without soft tissue augmentation) group. This will be the first evidence of the longitudinal tissue changes around immediate implant, and the first RCT comparing the clinical efficacy and esthetic outcome of xenogenic soft tissue substitute (i.e., from the non-living bone of another species) to the gold standard approach (CTG) on the immediate implants.
Introduction: Previously published studies report a prevalence ranging from 35.9% to 58.7% of the general population with at least one impacted wisdom tooth. Surgical extraction of wisdom teeth is the procedure most often associated with postoperative complications, such as pain, swelling, trismus, and oral discomfort during the first postoperative days. These complications arise from an inflammatory response, which is a direct and immediate consequence of the surgical intervention and can limit the patients' daily functions in the recovery phase and compromise their quality of life. Several methods have been used to control postoperative morbidity related to wisdom tooth extraction, including administration of proteolytic enzymes, tube drains, cryotherapy, anti-inflammatory and analgesic drugs and low level laser therapy. Objectives: To test whether the use of low power laser can improve post-operative pain, swelling and healing of the surgical wound. Material and methods: A double-centre, randomised, split-mouth, double-centre clinical study will be carried out in 38 patients per centre, totalling 76 patients and 152 wisdom teeth, who will undergo surgery for the extraction of the lower third molars. The necessary data for the study will be taken on the days of the consultation for surgery planning, on the day of surgery, by the patient on each post-operative day and on the 7th post-operative day (at the time of suture removal ).
The study is looking to see if a new drug (remimazolam) that is used to sedate and relax adults (aged 18-59 years) having dental treatment is better than the current drug in use (midozolam). Intravenous sedation is where a drug is injected into a patient's hand or arm. The drug stops them feeling worried, and helps them relax. After sedation, patients wait in a recovery area until they are safe to walk but the side effects of the drug can last until the next day. A new drug has been developed that has the same sedation effect and safety, but the recovery is much quicker. The investigators think that the side effects from the new drug will have worn off by the time patients are ready to leave the hospital. Patients who are coming to Guy's Hospital to have their wisdom tooth extracted under sedation will be asked if they want to be included in the research. Patients will be randomised to receive either remimazolam of standard of care midazolam. The sedation and dental treatment will be carried out in the normal way. The patients will be asked to do will be some questionnaires and some tests which are as follows: 1. Patients are asked to listen to some words and repeat them back. This tests how well they can remember new information 2. Reaction test - Patients are asked to rest their fingers on a keypad and move their fingers when lights come on above them. This tests how quick their reactions are. 3. Symbol test- Patients are asked to draw small shapes that are linked to numbers. This tests how well they can process information. 4. Standing test- Patients are asked to stand on a platform that measures how much they are swaying back and forth. This tests how stable they are to walk. By testing people before and after the sedation the investigators can see how they recovered and compare the two drugs. The research will take place during the day case visit and involve 2 x 30 mins research assessments (before sedation and post sedation). After the post-sedation tests, participants will be discharged, followed by a telephone review 3-10 days post procedure.
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.
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.
This study will involve 14 patients with mandibular premolars indicated for extraction and immediate replacement. The patients will be randomly allocated into two groups and each patient will receive one implant. In Group A, a CGF membrane will be laid in the implant cavity. While in Group B, a PRF membrane will be laid in the implant cavity. Bone graft material will be applied to fill the empty parts of the socket. Resonance frequency measurement will be done using the OSTELL device intraoperatively, at the 1st week and after 3 months. Cone-beam computed tomography will be done preoperatively, immediately following surgery, and after 3 months
study proposes an alternative atraumatic tooth extraction procedure; Apically achieved exodontia, which might offer an alternative to the conventional incisal exodontia, whilst providing minimum tissue trauma and subsequently maximum marginal tissue preservation.
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
Management of the jumping gap in the Vestibular Socket Therapy. And to study what is the best technique to manage this gap for optimal esthetic result.
Our study compared two different forceps for extraction of mandibular molars, the conventional extraction forceps and the Physics forceps. We assesed the relative pain score, patient satisfaction, success of extraction, incidence of alveolar plate fracture and soft tissue healing; post extraction. Our results found statistical significance in comparison of both forceps under relative pain score, patient satisfaction and soft tissue healing post extraction.
