title: Use of Narrow-Diameter Implants in Treatment of Severely Atrophic Maxillary Anterior Region With Implant-Supported Fixed Restorations.
abstract: The edentulous anterior atrophic maxilla represents a challenge for the surgeon and restorative dentist. Soft- and hard-tissue augmentation procedures are often required prior to, or simultaneously with, implant placement. A well-planned treatment protocol, patient compliance, and collaboration between the treating clinicians and the laboratory are requirements in achieving predictable long-term outcomes that satisfy patient expectations. Avoiding transmucosal loading and movement of the graft during the healing phase are crucial factors in achieving lasting success. In this case report, a fixed provisional restoration supported by four immediately loaded narrow-diameter implants (NDIs) was used to enable function during healing and protect the grafted site. Two of the NDIs, along with three conventional-diameter implants, were subsequently used to support the final restoration. NDIs with diameters of less than 3 mm can achieve excellent long-term osseointegration and may be used together with conventional implants for definitive prosthodontic treatment as demonstrated by the 11-year follow-up reported in this case.
