Abstract:

BACKGROUND: Alveolar bone plays an important role in denture stabilization and load bearing of bite force. It also has a great relationship with the treatment effect of prosthodontics. Therefore, it is particularly significant to avoid alveolar bone absorption and promote bone formation after tooth loss.
OBJECTIVE: To summarized research progress about socket preservation and to discuss the negative effect about periodontal flap surgery and immediate implantation.
METHODS: Computer-based online search of Medline database and CNKI database from 2005 to 2011 was performed. Key words were “alveolar preservation, socket preservation” in English. Duplicate articles were excluded. Finally, 34 articles were selected.
RESULTS AND CONCLUSION: It has a good result to apply growth factor, artificial bone graft, guided bone regeneration, bone tissue engineering regeneration technology to preserve alveolar bone. The periodontal flap surgery provides a broad vision when teeth extraction. But it accelerates the alveolar bone absorption. Immediate planting technology can not prevent alveolar bone absorption effectively. Therefore, it should take a consideration whether periodontal flap surgery and immediate planting technology is applied
