title: Split pedicle roll envelope technique around implants and pontics: a prospective case series study.
abstract: Recreating a harmonious gingival contour for contiguous missing teeth in the anterior maxilla is challenging. The aim of this study was to evaluate a split pedicle roll envelope technique designed for pontics. Twelve patients presented a labial flat or concave profile at the implant and pontic sites before second-stage surgery. The contour deficiency was compensated with a palatal split pedicle flap with the implant part rolled into the labial envelope and the pontic part covering the denuded ridge. Interim restorations were screwed in to guide tissue remodelling. The labial convex profile (CPF) and facial mucosal level (FML) at the implant and pontic sites, the Jemt papilla index (PIS) in the different restorative environments, and peri-implant bone levels were recorded at baseline and at 1 week, 3 months, and 6 months postoperative. Results showed that the CPF had increased by 1.4mm at the implant site and 1.5mm at the pontic site at 6 months after surgery. PIS had increased by 2 at the implant-tooth/pontic-tooth sites and by 2.6 at the implant-pontic site. FML was coordinated with that of the contralateral teeth. All indices were favourable at 3 months and then remained stable. Within the limitations identified, this combined therapy can be considered as an alternative to achieve aesthetic success when contiguous maxillary anterior teeth are missing.
