Abstract
Guided bone regeneration (GBR) is a well-established technique for managing alveolar ridge deficiencies, particularly in the esthetic anterior maxilla region. Various graft materials, including autografts, allografts, xenografts and alloplastic materials, are used in guided bone regeneration technique. Among these, deproteinized bovine bone mineral (Bio-Oss®) provides an osteoconductive scaffold that preserves ridge volume and supports implant stability.
This report describes a 23-year-old male patient with missing maxillary incisors (12, 11 and 21) who underwent guided implant surgery followed by simultaneous GBR using Bio-Oss® and a resorbable collagen membrane (T-Gen membrane). Delayed loading protocols were employed to enhance osseointegration and long-term functional outcomes. Digital planning and surgical guides ensured precise implant placement. Clinical and radiographic evaluation demonstrated successful ridge augmentation, stable peri-implant bone levels and favorable esthetic outcomes. This case highlights the predictability of GBR combined with guided implant surgery and delayed loading in restoring both function and esthetics in the anterior maxilla region.
