ABSTRACT
Parameters such as the correct 3-dimensional positioning and the quality of peri-implant soft tissues are fundamental to the success of implant-supported restorations. Digital planning and guided surgery techniques can make the implant placement more accurate, and modifying the periodontal phenotype is often fundamental to increasing esthetics and peri-implant health, mainly in esthetic areas. This article describes a guided surgery technique that assists in the 3-dimensional positioning of implants and identifies the best anatomic area (volume and safety) for obtaining a palatal gingival graft.

Making an intraoral digital scan of the emergence profile is a clinical challenge. The peri-implant soft tissue collapses after removal of an interim prosthesis, which compromises the correct design of a definitive implant-supported prosthesis. Although techniques are available for digitally reducing such a distortion, achieving a correct alignment of scans to replicate the internal and external characteristics of the peri-implant tissue is still challenging. This article describes an alternative technique for achieving a precise alignment of the peri-implant soft tissue emergence profile generated with an interim prosthesis.

Making an intraoral digital scan for fixed mandibular implant-supported complete-arch prostheses is a clinical challenge. The absence of references in the mandibular arch for precise scan alignment may complicate the correct digital design of the prosthesis framework. This article presents a straightforward method that allows a completely digital approach to digital scanning for fixed mandibular implant-supported prostheses.
