Factors to consider in selecting an occlusal concept for patients with implants in the edentulous mandible.
This article discusses 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. In a maxillary Kennedy class I or II situation, either group function or balanced occlusion is advocated depending on the characteristics of the opposing dentition. When a complete dentition is present in the maxilla or in the case of a Kennedy class III or IV situation, mutually protected occlusion or group function is recommended depending on the length, position, and number of implants. It is stressed that detailed preimplant placement diagnosis and treatment planning are essential to obtain a high standard of treatment with overdentures supported and retained by implants.
