Filter by:Bone healing is affected by smoking, particularly healing of extraction sockets, showing deficiencies in vertical and horizontal bone dimensions compared to the healing of non-smokers. Several approaches have been made to stimulate. Bone wound healing, including human autologous blood-derived fractions. One of these fractions is the leukocyte platelet-rich fibrin (L-PRF). L-PRF has been evidenced as potentially beneficial in promoting bone defect filling in alveolar bone and socket preservation in non-smokers. However, scarce evidence is related to this beneficial effect in smokers. This clinical trial aims to study and compare the in vivo effects of L-PRF during bone wound healing and regeneration in smokers. The main question is: Has the L-PRF a beneficial effect during alveolar ridge preservation in smokers? After consent, participants with tooth extraction indications and implant rehabilitation treatment will be enrolled. After randomization, participants will be assigned to an experimental group treated with L-PRF plugs and membranes or a control group (physiological healing). Participants will receive two interventions: - First intervention: Tooth extraction, intraoral scan, and Cone Beam Computed Tomography in the treated zone. - Second intervention (4 months after first intervention): intraoral scan and Cone Beam Computed Tomography in the treated zone
Patients with long span, narrow edentulous ridge in the posterior mandible underwent piezotomed ridge splitting and osseodensification with simultaneous implant placement.
Evaluation of the marginal bone and soft tissue alterations after the OsseoSpeed™ EV Profile implants placement in anterior maxilla. The following parameters will be tested: - pink esthetic score - at the temporary crown delivery, at the final crown delivery, 6 months post final crown delivery - papilla index - at the temporary crown delivery, at the final crown delivery, 6 months post final crown delivery - changes in radiographic marginal bone levels and width at buccal and palatal aspects: differences between baseline (the day of surgery) and 1-year post-op measurements on CBCT will be made.
A prospective randomized controlled trial of 30 patients from the Faculty of Dentistry of the UFJF was conducted. It was included patients who presented indication of extraction of premolars, canines or incisors. All the thirty patients underwent dental extraction and were randomly divided into three groups according to the study methodology. Plaster casts and Cone-Beam Computed Tomography (CBCT) exams were performed for comparative analysis between sample groups and between study times ( imediate postoperative and four months later).
