Filter by:the goal of this clinical trial is to learn if the new osseo-densification technique works to provide enough bone width and quality prior to implant placement in the upper jaw the main question it aims to answer is: Is the use of osseo-densification protocol better than the standard alveolar ridge widening techniques; regarding efficiency and comfort in obtaining sufficient alveolar ridge width in horizontally atrophic alveolar ridges?
The aims of the study was to correlate the extent of the dimensional alveolar bone changes after tooth extraction and contextual guided bone regeneration with serum vit D levels in 14 patients. Moreover, at 4 months, a small bone sample was collected in order to correlate histological and immunohistochemical parameters of bone with vit D serum levels.
split-mouth RCT, 25 months follow up. GBR protocol with LPRF as grafting material in the test group and autogenous bone with DBBM as grafting material in the control group.
The goal of this clinical trial is to evaluate the safety of placing TiO2 scaffolds in alveolar ridge and to evaluate if the scaffold material contributes to maintain the anatomy and the volume of the alveolar process after tooth extraction.
two groups of inserted implants: trans-gingival and under-bone level; difference in the marginal bone loss at six months from placement between the two groups of implant positioned in the posterior atrophic maxilla
The aim of this randomized prospective clinical trial was to evaluate the outcome of bone block harvesting from the retromolar region using the Conventional and Piezosurgery Method. The study was planned on 19 patients (13F,6M) on 31 donor sites. In patients with bilateral bone harvesting, the donor site and the surgical method to be used were determined by the randomization protocol, while in patients with bone harvesting from a single site, the donor site was determined by considering parameters such as proximity to the operation site and distance to the inferior alveolar nerve. Clinical parameters such as operation time, pain, swelling, trismus, nerve damage were evaluated.
The study was conducted on 20 immediate implant placement sites in the anterior maxillary region. In the study group, 10 implants were inserted using socket shield technique, while in control group, 10 implants were inserted using conventional immediate placement technique. All patients received immediate and 6 months post-operative CBCT to assess horizontal bone loss, vertical bone loss, and measurement of bone density. Implant stability quotients (ISQs) was measured immediately, 1st, 3rd and 6 months post-operatively.
this study aims to evaluate horizontal bone augmentation achieved at the anterior maxilla using computer-guided cortical shell bone technique and accuracy of fixation of the bone shell away from the atrophic ridge by a calculated distance which is always a challenging step for inexperienced surgeons to fix a cortical shell at the ideal position in the conventional protocol it was never guided to be precisely fixed at the proper position and angulation the problem is if it fixed with insufficient distance with proposed volume loss leads to totally insufficient volume gain for future implant placement also to evaluate the efficacy of the CAD/CAM surgical guide during chin harvesting procedures in reducing the risk of anatomical structure damage and patient morbidity with more accuracy compared with the standard technique. this trial versus free hand conventional cortical shell bone technique both harvested from symphysis area (chin).
According to previous scientific evidence lining on biological concept of bone regeneration into the maxillary sinus, an observational study was set up to record possible (hypothesized) difference in bone formation between different width of the maxillary sinus itself. Therefore, a multicenter study was set up that foresaw a surgical intervention of sinus lift with lateral approach, the 6 months healing phase, the implant insertion in two sites with the implant site preparation made by a trephine bur to retrieve a bone specimen for histomorphometric examination without any additive invasively for the patient.
The study evaluated the effect of local application of simvastatin around immediate implant on the amount of gap fill, ridge dimensional alterations and bone density in humans.
