Filter by:A patient with a tumor lesion of the chest wall undergoes CT scan with a step width of less than 1 mm, then engineers design an individual model to replace the defect. Using a 3D printer, a model is made based on titanium alloy powder. Preoperative preparation takes an average of 14-21 days. The next stage is surgical treatment in the amount of resection of the chest wall with plastic defect with an individual titanium implant. In some cases, the titanium framework is separated from the pleural cavity by a polytetrafluoroethylene plate in order to seal and prevent the development of pulmonary hernias. The advantages of titanium individual prostheses include accurate matching of the implant to the size and characteristics of the defect, individual modeling allows you to repeat the anatomical features of the patient. This method helps to recreate the original shape of the chest, and most importantly, symmetrical, relatively healthy half. With the help of titanium, individualized prostheses are made based on 3D modeling, which will reduce the incidence of complications, accelerate rehabilitation and improve the quality of life of patients with tumor lesions of the chest wall. The postoperative period takes 15-30 days.
The digital workflow in dental implantology has been used for planning the cases with the intraoral scanners and computer tomography, together helping clinicians to be more accurate and precise. Today, thanks to digital technology clinicians can plan from surgical to the final prosthesis using 3D models and cad-cam machines. The aim of this research is to validate the full digital workflow for the single-tooth implant rehabilitation. A total of 19 patients (22 implants) were included in the present study with mean follow-up time of 2 years. A full-digital workflow was performed on each patient through the design and printing of a surgical guide, the taking of the impression with an intraoral scanner and the CAD-CAM design of the crowns.
this study was to compare the bone height changes around three implant telescopic, locator, and ball retained mandibular overdentures. radiographic changes in peri-implant tissue in three groups were evaluated
Twenty compromised post-extraction sockets were managed by VST and IMP. After tooth extraction and IMP, a vestibular incision was cut and a cortical bone shield was stabilized. The jumping gap was then filled with particulate bone graft, which was protected by a healing abutment. After 2 years labial plate thickness was evaluated at 3 levels (crestal, middle and apical) using cone beam computed tomography (CBCT). Pink esthetic core (PES), and probing depth (PD) were also measured. 2 year following implant placement, the mean differences (µ) and standard deviations (SD) were calculated. Paired t-test was used for detecting significant results at P≤.05.
The aim of the present study was to evaluate the peri-implant crestal bone level around implants placed 1.5 mm subcrestally, with a 1 mm or 3 mm definitive abutment height at the time of implant placement after 1 year. Patients were selected from the Department of Periodontology at Universitat Internacional de Catalunya. X-rays were taken at the time of implant placement, 8-12 weeks after placement, after screwing the provisional rehabilitation and at 12 months. An examiner indicated the crestal marginal bone level, the marginal bone level of the implant, and the marginal bone level of the abutment . The examiner, independent to the study, carried out the radiographic analysis using the Image J software on periapical radiographs.
Commercially available implant surfaces are moderately roughened surfaces and they are obtained by acid-etching following alumina or titanium oxide grit-blasting. Although the micro-rough implants can be successful in compromised clinical scenarios, the bioinert nature of titanium surfaces cannot stimulate a more rapid bone regeneration and mechanical fixation of dental implants. Laser surface treatment is used to produce an implant surface modification on the nano-scale with controlled and reproducible patterns in addition to exhibiting a sterilizing effect and achieving efficient oxidation .
