The long-term success of dental implants is critically dependent on the availability of adequate alveolar bone volume and quality. Bone grafting is a fundamental procedure to address bone deficiencies, enabling proper implant placement and osseointegration. This systematic review analyzes the scientific evidence related to implant placement with bone grafting, evaluating the effectiveness of various techniques and materials. A comprehensive literature search was conducted in PubMed, Scopus, and the Cochrane Library using keywords such as "dental implant," "bone grafting," "guided bone regeneration," "osseointegration," and "sinus lift." Five key sources were selected for in-depth analysis: one Cochrane systematic review, one case study, one animal study, and two literature reviews. The main findings indicate that bone grafting is highly effective in improving implant success rates in patients with bone deficiency. Guided bone regeneration (GBR) and sinus lift are well-established, evidence-based techniques, with various bone graft materials, including bone substitutes such as Bio-Oss, showing good results. Animal studies have shown the potential of alternative materials such as chitosan and collagen, while advancements in GBR membrane coatings hold promises for improving the effectiveness of this technique. In conclusion, bone grafting is a crucial and effective component for implant success in patients with bone deficiency, with the selection of techniques and materials requiring careful clinical evaluation. Further research, especially high-quality clinical trials, is needed to evaluate the comparative effectiveness of different techniques and materials and the potential for new materials
