Despite these advancements, challenges such as peri-implant tissue recession, sinus complications, and aesthetic concerns persist. Bone augmentation and soft tissue enhancement techniques, including sinus lifts, connective tissue grafts, and buccal fat pad utilization, have been employed to address these issues with varying degrees of success. However, the need for predictable and stable bone regeneration and soft tissue contouring remains critical for long-term implant success.\n\nThe following study aims to assess bone gain, soft tissue contour, and stability after using bone lamina shell, providing a potential solution to enhance peri-implant tissue integrity and optimize functional and aesthetic outcomes in zygomatic implant rehabilitation",[75],"Zygomatic Implants",[77,78,79],"Zygomatic implants","Grafting","Tunnel and channel","NOT_YET_RECRUITING","2026-02-01",{"date":83,"type":84},"2026-02-06","ACTUAL",{"date":81,"type":69},{"date":87,"type":69},"2027-01-01",{"name":5,"class":6},1]
