Aims: Reliable implant-supported rehabilitation of an edentulous alveolar ridge needs sufficient volume of bone. In order to achieve a prosthetic-driven positioning, bone graft techniques may be required. This clinical case report demonstrates the success of Conelog dental implants in the horizontally augmented maxillary arch. Case: The 64-year-old female patient with missing left lateral, canine, premolars and molars, had her atrophic ridge augmented with a xenogeneic bone graft and titanium membrane fixed with pins. After 6 months, three dental implants (Conelog; 3.8x11mm, 3.8x11mm and 4.3x11mm, respectively) were placed in an optimal three-dimensional position in the canine, second premolar and second molar regions into the newly formed bone. Four-months later, definitive metal-ceramic fixed dental prosthesis were constructed and cemented with a dual-curing resin cement (Rely X U-200, 3M ESPE). The patient was followed for 2 years and exhibited uneventful progress about the bone levels and periodontal health. Conclusion: This case report suggests that bone level dental implants allow proper primary stability followed by augmentation procedures performed using xenogeneic bone graft and titanium membrane in the reconstruction of the atrophic maxilla.
