Abstract:

BACKGROUND: Currently, there are few clinical data about the speed of peri-implant bone resorption with different times.
OBJECTIVE: To observe the bone resorption of alveolar around after transplanting implant, and to evaluate the effect of time factor on peri-implant bone resorption.
METHODS: All the direct digital panoramic films of oral implant cases after surgery from 2003 to 2010 were collected. Panoramic films for analysis were divided into immediate pieces, 1, 3, 6, 12 months groups after implantation. All the panoramic films were measured. The speed of peri-implant bone resorption at different post-operation times was compared.
RESULTS AND CONCLUSION: There was significant difference of the peri-implant bone resorption rate at different post-operation times from 1 to 6, 3 to 6, 1 to 12, 3 to 12 months (P < 0.01). It is indicated that the maximal peri-implant bone resorption occurs at 1-3 months after implant surgeries.
