Abstract
Background: Mandibular reconstruction poses challenges in achieving functional and aesthetic outcomes. Effective oral rehabilitation is crucial for restoring function and improving quality of life; however, the altered neomandibular anatomy complicates oral hygiene, increasing the risk of peri-implant complications and making successful rehabilitation more difficult. This study introduces a novel approach combining vestibuloplasty with patient-specific implant-retained splints to enhance oral health and improve rehabilitation outcomes. Methods: Three patients underwent mandibular reconstruction with a free vascularized fibula flap (FFF). After 6 months of osseointegration, vestibuloplasty and soft tissue refinement were performed, with a split-thickness skin graft placed on the FFF periosteum. An implant-retained splint was secured to the abutments for two weeks to support soft tissue healing. Implant survival, bone loss, and peri-implant health were evaluated over a 2-year follow-up. Results: A total of 12 implants were placed, primarily in the neomandible (83.3%), with a 100% survival rate. Implant survival was assessed. Implant survival was assessed based on established criteria for clinical success, including stability, presence of pain, bleeding on probing (BOP), pocketdepth, bone loss and lack of peri-implant radiolucency. Functional outcomes included normal mouth opening, laterotrusion, and protrusion. Pocket depths ranged from 3 to 4 mm, except for one implant in cases 1 and 2. The mean BOP was 51.7%. Conclusions: This case series introduces a surgical technique that combines CAD/CAM and vestibuloplasty to optimize dental rehabilitation in mandibular FFF reconstructions, demonstrating safe thinning of soft tissues for improved oral hygiene and survival.
