ABSTRACT
OBJECTIVE: To investigate the effect of Straumann implant on crown appearance in the immediate implant restoration of maxillary anterior teeth. METHODS: This study was conducted among 86 patients undergoing immediate implant restoration of maxillary anterior teeth between January and December, 2018. We randomized the patients into control group for treatment with immediate implant restoration and study group receiving additional Straumann implant. The effects of restoration, bone absorption at 6 months, implant length, implant diameter, root protrusion, gingival color, far and middle gingival papilla, lip side gingival height, near and middle gingival papilla, and lip side gingival curve were compared between the two groups. RESULTS: The repair effect in the study group was better than that in the control group (P < 0.05). The implant length and implant diameter were significantly greater in the study group than in the control group. The root protrusion, gingival color, far and middle gingival papilla, lip side gingival height, near and middle gingival papilla, and lip side gingival curve were all better in the study group. The height of marginal bone in the study group was significantly higher than that in the control group (P < 0.05). CONCLUSIONS: Straumann implant can be used in immediate implant restoration of maxillary anterior teeth to achieve a better aesthetic effect.
