The commonly used titanium alloy dental implants currently apply solid structures. However, issues such as stress shielding and concentration may arise due to the significant difference in elastic modulus between implant host. In order address these problems, this paper proposes five porous structures based on Gibson-Ashby theoretical model. We utilized selective laser melting technology shape a structure using Ti-6Al-4V material precisely. mechanical properties of were verified through simulation compression experiments. optimal structure, which best matched human bone, was circular ring with pillar diameter 0.6 mm layer height 2 mm. strain surrounding cortical cancellous bone under different biting conditions studied verify effectiveness alleviating both standard osteoporotic conditions. results confirm that meets requirements provides basis for clinical implantation.

A maxillary sinus lift procedure is indicated if a dental implant needs to be placed in the posterior maxilla with limited bone available accommodate implant. Both open and closed lifting procedures are reliable approaches for increasing volume needed support proper positioning. However, these methods can lead several complications. In addition general complications commonly linked oral surgery, such as swelling or hematoma, primary complication typically perforation of Schneiderian membrane during osteotomy. Detailed extensive presurgical evaluation crucial minimize The objective this study was delineate contemporary trends specific emphasis on different techniques procedure, anatomical surgical factors, evaluation, grafting, practical implications factors dentistry cases involving deficient maxilla. conclusion, while both osteotome lateral window assist clinicians addressing complexities placement maxilla, height before implantation remains critical factor determining success longevity implants.

Oral maxillofacial rehabilitation of the atrophic maxilla with or without pneumatization maxillary sinuses routinely presents limited bone availability. This indicates need for vertical and horizontal augmentation. The standard most used technique is sinus augmentation using distinct techniques. These techniques may not rupture membrane. Rupture membrane increases risk acute chronic contamination graft, implant, sinus. surgical procedure autograft involves two stages: removal preparation site graft. A third stage often added to place osseointegrated implants. because it was possible do this at same time as graft surgery. new bioactive kinetic screw (BKS) implant model presented that simplifies effectively performs autogenous grafting, augmentation, fixation in a single step. In absence minimum height 4 mm region be implanted, an additional performed harvest from retro-molar trigone mandible provide bone. feasibility simplicity proposed were demonstrated experimental studies synthetic digital torque meter measure MIT MRT during insertion removal. amount determined by weighing material collected BKS implant. here benefits limitations installation dental implants simultaneously.
