- •10. To be able and to agree to undergo treatment and follow up at least 10 times.
- •1. Maxillary complete denture must have good marginal fit and retention with acceptable esthetics.
- •2. Mandibular complete denture must have proper marginal fit and its thickness at the areas of the implants must be at least 6 mm.
- •3. Occlusal plane of denture should be parallel to interpupillary line, ala-tragus line, balanced occlusion and no severe occlusal interference.
- •The title of research that concentrate at mandibular overdenture. Because of about the occlusal concepts when making implant-supported and implant-retained mandibular overdentures. The dentate or edentulous condition of the maxilla plays a significant role in this respect. If the maxilla is edentulous, balanced occlusion is indicated. It is stressed that detailed preimplant placement diagnosis and treatment planning are essential to obtain a high standard of treatment with overdenture supported and retained by implants31.
