Objective: To analyze the stress distribution of short dental implant with different length and diame-ter in the type Ⅳ jaw bone of maxillary posterior area, providing the theoretical basis for the clinical de-sign of short dental implant in the maxillary posterior region. Methods: Three dimensional finite element was used to simulate the stress size and distribution of implant-bone interface in 7 kinds of Bicon im-plants with different diameters and lengths under vertical loading and a 45 degree slope loading。 Results: The effect of implant diameter on bone interface was more significant than that of length, regardless of vertical load or lateral load. Under the lateral load, the von-mises stresses of group 6*6mm was mini-mum. Under the vertical load, the von-mises stresses of group 6*8mm was minimum, the second place was group 6*6mm. There were no significant difference between 5mm diameter implants with different length. Conclusion: The choice of short implant in the type Ⅳ jaw bone of maxillary posterior area: if the bone in good conditions, 6*6mm implant was suggested, if the bone in moderate conditions,5*6mm im-plant was suggested, if the width of bone was not enough, 4.5*8mm implant was suggested.

Objective: To compare the clinical effect of immediate implant and delayed implant in dental resto-ration of a single anterior tooth-missing. Methods: Thirty-six patients undergoing anterior single tooth replacement with implants in our hospital from Jan 2013 to Dec 2016 were divided into immediate im-plant group(n=18) and delayed implant group(n=18). After the treatment, soft tissue around the implant was evaluated by the pink esthetic scores(PES) and the vertical resorption of alveolar bone were measured by CBCT. Results: The success rate of the two groups were 100%(P>0.05). The PES of the immediate group were higher than that of the delayed group at the time of final restoration, 6m after final restoration and 1y after final restoration(P<0.05). The vertical bone resorption distance of immediate implant group were significantly lower than that of the delayed group at the time of final restoration and 1y after final res-toration(P<0.05). Conclusion： The success rate of immediate implant and delayed implant were high. Compare to delayed implant, the vertical bone resorption were less and the esthetic effect of soft tissue around the implant were higher by immediate implant.
