Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of dental implant equipment, and more specifically, it relates to a drilling guide plate. Background Technology
[0002] Personalized titanium mesh is a commonly used instrument in Guided Bone Regeneration (GBR) surgery. It protects autologous bone or artificial bone grafts placed in the bone defect area and maintains the intended space for bone regeneration. During surgery, the personalized titanium mesh needs to be secured to the alveolar bone to maintain its position and shape. This process is typically achieved using bone screws. Bone screws are small titanium alloy screws that provide sufficient mechanical support to ensure the stability of the personalized titanium mesh in the bone defect area.
[0003] Currently, doctors primarily rely on clinical experience to determine the placement of bone screws. A small ball drill is used to drill holes in the alveolar bone. After a personalized titanium mesh is placed in the appropriate area, the bone screw is passed through the mesh and screwed into the fixation hole in the alveolar bone to secure it. However, relying solely on clinical experience to determine the location of the screw hole in the alveolar bone makes it difficult to ensure that the hole is drilled in the correct position.
