[Clinical study of immediate implant].

OBJECTIVE

To evaluate the clinical result of immediate implant.

METHODS

32 cases underwent immediate implant surgery for 59 implants simultaneously when the teeth or roots extracted. 55 implants were placed with bone grafts or bone substitutes. The second stage operation were performed in the sixth month and ceramic crown were fixed in the seventh to eighth month postoperatively, the follow up were mean 39 months.

RESULTS

One implant was lost. Bone resorption of alveolar crest was observed in 4 implants. Mean resorption was 2 mm.

CONCLUSIONS

The result of immediate implant is predictable, the advantages are avoiding the alveolar bone resorption after teeth extraction, implant could be placed in an ideal position; less operation trauma, good esthetics results.
