High Water Hybrid

Dr. C. asks:

I am restoring an edentulous mandible. Originally I treatment planned for five 4.0×10 mm dental implants between the mental foramens. Because of bone quality, I could only place five 3.25×10 dental implants.

I plan to insert an FP3 (crowns with pink gingival) and use a UCLA type
attachment where I could screw the bridge directly into the dental implant
fixtures. I plan to use acrylic teeth and acrylic gingival on a metal
framework. I am wondering if a fixed detachable (high water hybrid) might be a better fit for these circumstances? I would appreciate any
comments. Thanks.
