Model Details: According to the construction technique for the maxillary complete denture and mandibular overdentures, the patients will be classified randomly and equally into two groups. Group I: patients receive maxillary complete denture opposed to four implant-assisted mandibular overdenture constructed with conventional method. Group II: patients receive maxillary complete denture opposed to four implant-assisted mandibular overdenture constructed with CAD/CAM milling.
