Abstract

|
|
Purpose: The aim of this study is to investigate changes in the marginal bone level where a scalloped implant was placed as well as to evaluate the influencing factors, such as time of placement or area of placement.
Materials and Methods: The participants of this study included patients who received a scalloped implant fromApril 2011 to October 2012 and visited the Department of Prosthodontics, Gangnam Severance Dental Hospital after over 12 months. The survival rate and changes of mesial and distal marginal bone levels were calculated. In addition, the factors influencing the marginal bone level were evaluated according to the time of placement, area of placement and time. Subsequently, a statistic analysis was performed using an independent t-test and a linear mixed model. The significant level was 95%.
Results: Thirty-five patients with 43 scalloped implants were included in this retrospective study. Changes of marginal bone level were 0.34 mm mesially and 0.29 mm distally. There were no statistically significant differences among all of the influencing factors, except for time.
Conclusion: In conclusion, the present study suggests that the use of scalloped implant can be a predictable treatment option even in areas where mild dehiscence exists on the buccal plate.
