Bone Changes Assessment in Screw-Retained Maxillary Complete Denture With Electric Welded Framework Versus Cast One

Bone Changes Assessment in Screw-Retained Maxillary Implant Supported Complete Denture With Electric Welded Metal Framework Versus Cast One (Randomized Control,Split Mouth Trial)

comparing bony changes around implants that will be joined by ametal framework either with electric weiling or with the conventional casting metal

joining multiple implants together in the edentulous arches is considered agood solution, using the conventional casting technique has many disadvantages due to lab errors and time and cost consuming on ,the other hand the study aims to owercome these disadvantages using electric welding metal framework.
