[Clinical observation of the reliability of gingival contour by using temporary crown after loading 1 year]
1Department of Second Dental Center, Peking University School and Hospital of Stomatology, Beijing 100101, China.
Objective:
To observe the gingival contour and its variation following application of implant-supported temporary crowns on gingival contour in maxillary single tooth implant procedure after loading 1 year and to explore the reliability of soft tissue intervention using temporary crowns.
Methods:
In 78 (37 males and 41 females) patients with anterior maxillary single tooth loss from the Department of Second Dental Center, Peking University School and Hospital of Stomatology, the gingival contour was induced by using implant-supported temporary crowns prior to maxillary tooth implant till permanent restoration from March 2010 to November 2011. The gingival papilla height and labial gingival margin level were measured immediately after the permanent restoration and 1 year later.
Results:
In all the cases after loading 1 year, the average mesial and distal gingival papilla heights in the implant area increased by (0.16±0.58) mm and (0.10±0.53) mm, respectively. The labial gingival margin level was changed by (0.10±0.41) mm averagely. The difference in gingival contour shaped by temporary crown was not statistically significant after 1 year (P>0.05).
Conclusion:
The soft tissue shaping technique on aesthetic rehabilitation in maxillary single tooth implant is clinically feasible with a good recent aesthetic effect under the condition that the complications are controlled stringently.
