Background: Implant placement on the anterior maxilla requires a comprehensive concern of adequate alveolar bone and gingival biotype. Insufficient support for hard and soft tissues becomes one of the main causes of implant complications. To avoid this problem, pre-surgical treatment with Guided Bone Regeneration (GBR) is suggested with respect to the alveolar ridge defect. Objective: In this study, we reported the predictability of a sandwich technique of GBR prior to implant placement. Case Presentation: Case: Thirty-four-year-old male was referred with a chief complaint of missing teeth on area #21 accompanied by labial bone dehiscence due to trauma. Bone thickness measurement displayed was approximately 3/4/5 mm (coronal/middle third/apical third of the alveolar ridge). This case was diagnosed as soft and hard tissue deformity on area #21 prior to implant. Case management: GBR and implant placement were performed in two stages of surgery. GBR was executed by using a combination of Biphasic Calcium Phosphate (BCP) (consisting of 40% Beta-Tri Calcium Phosphate (β-TCP) and 60% Hydroxyapatite (HA)) and Demineralized Freeze-Dried Bone Allografts (DFDBA) bone graft materials. Alveolar ridge re-measurement five months after GBR showed significant bone augmentation, 6/6/6 mm (coronal/middle third/apical third of the alveolar ridge). Furthermore, a 3.5 mm (diameter) x 10 mm (length) bone-level implant was inserted accordingly. The two-year follow-up exhibited gingival stability and no sign of either recession or bone resorption. Conclusion: Herein, we demonstrated the effectiveness of BCP and DFDBA bone substitutes to obtain proper conditions for the long-termed stability and predictability of implant.
